    Shrimp Pill Machine ·
    The inventor's son relates to one of the island pylons, which comprise cylindrical rollers, the longitudinal axis of which cylindrical rollers are parallel running and comprise first rollers of diameter D1 and second rollers of diameter D2 and third rollers of diameter D3 smaller than both D1 and D2, and at least first and the second rollers are adapted to rotate by an actuating element, which also comprises a motor assembly driving the actuating element.
    From US 8777701, a shrimp pellet machine of the kind mentioned in the introduction is known where the rollers sit on chain links and the jaw joints together form a closed chain as the shrimp is peeled during the forward movement of the chain. US 7811157 discloses a shaving pellet machine with parallel sized rollers of varying sizes having contact surfaces so that rotation of one of the rollers is at least transferred to a neighboring roll. The rollers are sloped with their axes at a common angle to the horizontal, so that during shelling, shrimps move from a high-lying area to a lower-lying area.
    Thus, it is the object of the present invention to provide a shaving pellet machine which does not have the disadvantages of the prior art, or which at least provides a useful alternative to the prior art.
    This is achieved in a first aspect of the invention in that the third rollers are spaced from both the first and second rollers, so that the surfaces of the third rollers do not touch either the surfaces of the first rollers or the second rollers.
    This makes it possible to drive one or more sets of the third rollers individually in a preselected direction of rotation and speed, so that the rotation of the third rollers can be controlled and controlled independently of the rotation of the first and second rollers. This provides a much more flexible shaving pellet machine. It is also possible to allow the third rollers to be freely rotatable, so that they are only rotated when pinching parts are clamped between their surface and an adjacent second or first roll.
    According to an embodiment of the invention, the distance between the surfaces of the first rollers and the third rollers and the distance between the surfaces of the second rolls and the third rolls is small, for example between 10/1000 mm and 1 mm or between 10/1000 mm and 1/4 mm, or preferably between 10/1000 mm and 100/1000 mm. In this way, the third rollers can be guaranteed independence from the first and second rolls even if there are variations in the manufacturing accuracy on the surfaces of the rollers.
    During operation of the rollers, the distance between the rollers may vary due to inaccuracies in the surface, or due to variations in the distance between a given surface portion and the axis of rotation of a given roll, or due to varying wear on the rollers' bearings. A roll may also be barrel-shaped or oval in cross-section or have longitudinal waves in the surface or other structures in the surface which give variations in distance within the specified ranges. In another aspect of the invention, additional advantages are obtained with a shaving pellet machine of the kind set forth in the introduction and wherein in the pellet area two or more predefined sets of rollers are rotated for rotation in preselected but changing directions of rotation by connection to one or more actuating elements. By operating multiple sets of rollers, a more active squeeze is achieved and grip of the shrimp shell in the gap between rollers whose surfaces move actively either toward the gap or away from the gap between two successive rolls or alternate between the two movements. It will now also be possible to arrange rollers which on one side are adjacent to a roll with the same direction of rotation where both rollers rotate either counterclockwise or clockwise so that the shrimp is not pulled down into the slot and on the other side is adjacent to a roll. roll, which is opposite to the direction of rotation, so that the upwardly facing surface of the rollers both moves toward the slot, so that the legs of the shrimp, tentacles and shell parts are pulled down into the gap between the driven rollers, or both upwardly moving away from the slot so that shrimps are thrown away from the slot. In one embodiment, it is also preferred that the activating element comprises at least one toothed belt comprising a first face and a second face, which first face with first means engages with the first roll and which second face with second means engages with the second roll. and the second rollers have the same or opposite directions of rotation. The first and second rollers, which are engaged with their respective surface of the toothed belt, will thus belong to each set of driven rollers.
    If a given roller rotates clockwise, a neighboring roller can rotate either counterclockwise or clockwise. This gives you four different ways to influence the shrimp, which lands in the gap between two neighboring rolls. Turning both rolls clockwise, the shrimp will tend to move across the crack from left to right. Turning both rolls counterclockwise, the shrimp will tend to move across the crack from right to left. Turning the roller to the left clockwise, and the roller to the right counterclockwise, the tent tentacles and other tends to move down the gap between the rollers. Turning the roller to the left counterclockwise and the roller to the right clockwise, the shrimp will tend to move up out of the crack and follow the surface of either the roller to the right or the roller to the left.
    The shrimp pellet machine may comprise a closed chain consisting of a plurality of joints containing cylindrical rollers, the longitudinal axis of the cylindrical rollers being angled 90 degrees relative to the shrimp pellet direction. The first and second rollers are rotated by actuation of first means in the form of, for example, gears or friction wheels driven by at least one toothed belt / friction belt connected to a motor assembly. The gears are mounted on a shaft which extends along the axis of rotation of the associated cylindrical roller.
    The gears are actuated by at least one toothed belt driven by an activator such as a servo motor. In this context, a toothed belt is also understood to mean drive belts which have such good contact / friction to the first and second means that the movement of the belt causes rotation of the means and thus the rollers, and that the belt does not slip, but that the whole translational movement is transferred to the rotation. In one embodiment of the shrimp pellet machine, the third rollers in the pellet area are rotated by a further actuating element arranged to operate a first set of the third rollers in a first direction of rotation, and the actuating element being further adapted to operate a second set of the third rollers. A set of rollers comprises one or more predefined rollers which are operated in the same orbital direction. Thus, it is also a given that the sets are always disjointed, so that a roll cannot belong to more than one set of driven rolls in the shrimp pellet area.
    For the three sets of rollers defined here, namely the first rolls, the second rolls and the third rolls, there are then a total of 8 different operating options, where the first and second rolls can be operated in four different ways and each of these four ways can the two sets of third rollers are operated either clockwise or clockwise. However, since the third rolls are divided into two disjoint sets, which are always operated in opposite directions, however, the number of choices is not increased beyond 8. In one embodiment, it is preferred that the following sequence of rolls be repeated in a pellet area: one of the first rolls, one of the first set. of the third rolls, one of the second rolls and one of the second set of the third rolls. Hereby it is obtained that two consecutive of the third rollers in the shrimp pellet area are always driven by the additional actuating element in opposite directions of rotation. In one embodiment of the shaving pellet machine, the additional actuating element comprises a drive wheel, which operates a closed drive belt with external and internal drive surfaces where the movement of the two drive surfaces is transmitted to the first and second sets of the third rollers, respectively, via a drive wheel directly coupled to each third roller. For example, since, for example, the first set of the third rollers is coupled via their drive wheels to the inner drive surface of the closed drive belt, and the second set is coupled to the outer drive surface of the closed drive belt, the two sets of rollers will run in opposite directions of rotation. The coupling between the drive surfaces of the closed drive belt and the drive wheels drive wheels can be direct or via intermediate drive belts. In a further embodiment, it is preferred that the drive wheels coupled to the third rollers are mounted directly on extensions of the longitudinal axes of the third rollers exterior to the bearing of the roll, whereby the first and second sets of the extended longitudinal axes each have their respective lengths on which the drive wheels are mounted, thus that the first and second sets of the third wheel drive wheels sit along two straight parallel lines along the third roller bearings. This arrangement makes it exceptionally easy to select the sets of third rollers to be driven synchronously and to attach propellants, such as toothed belts to the drive wheels, which may thus be suitably constituted by gears.
    The further embodiment comprises precisely that the drive wheels of the third rollers consist of gears, the first set and the second set of the mounted gears of the third rollers being driven by each toothed belt, one toothed belt being in driving communication with the outside of the closed driving belt and the other toothed belt is in drive relationship with the inner side of the closed drive belt. This results in the two sets of third rollers being driven synchronously by the same drive mechanism, but in different directions of rotation.
    The sprockets of the rollers do not touch each other so the wear of the gears is minimal. It also has the effect that it is only in the pellet area that the rollers rotate, which is why the wear on them is also small. When installing the shrimp pellet machine in shrimp trawlers, the shrimp pellet process can be optimized by the speed adjustment of the motor driving the chain, as well as by the speed adjustment of the toothed belt (s) driving the cylindrical rollers.
    The shrimp pellet machine of claim 9 comprises a closed chain consisting of a plurality of joints comprising the cylindrical rollers, the longitudinal axes of the cylindrical rollers being oriented 90 degrees with respect to a shrimp pellet process direction in which an engine assembly drives the closed chain forward in the shrimp pellet direction. Hereby a machine is obtained which ensures the shrimp a fixed residence time in the area where the shrimp piling takes place, it is the propulsion of the rollers by the movement of the chain, which ensures the shrimp's way through the pellet area and not a more or less random slip.
    The shrimp pellet process itself is accomplished by the chain being driven in a shrimp pellet process in which shrimp to be peeled are applied to the chain at one end at an inlet to the horizontal course of the chain. The shrimp are subsequently peeled off by friction through contact with the rollers driven by activating the toothed belt (s). When the chain with associated rollers reaches the end of a horizontal course and begins a return movement opposite the shrimp pellet process, the now peeled shrimp falls off the rollers and can be intercepted by a suitable conveyor belt. The return cycle for the chain with all the rollers takes place below the horizontal pillar area.
    The released shrimp shells are collected under the chain between the pellet area and the chain's underlying return path. By using toothed belts / friction belts to rotate the gears / friction wheels and thus the first, second and third rollers, it is possible to make any rotation of the rollers, noting that the first rollers rotate in the opposite direction of rotation of the second rollers, and thus, the first and second rollers have the same orbital directions. Thus, they can rotate in one direction any number of times and then the opposite direction any number of times. This makes it possible to perform an optimal shrimp pellet process, since rotational speed and number can adjust the size of the shrimp and their degree of maturation.
    Shrimp in the known processes often mature artificially to facilitate peel. The artificial maturation can be reduced to a minimum here, in that the flexible setting of the rollers / rollers can regulate the residence time of the shrimp in the pellet area, and also how much friction they are subjected to, as the circulation speed can also be controlled.
    A long toothed belt can be used which, at a suitable abutment, has abutment surface against the gears of the first rollers, and with an abutment surface at the same time abuts against the gears of the second agitator and thus drives them synchronously. Two separate toothed belts can also be used, with one toothed belt driving gears belonging to the first rollers, while the other toothed belt driving gears belonging to the second rollers. The two toothed belts are driven so that the rollers / rollers run synchronously.
    The shrimp arrow machine can be mounted and operated in maritime vessels such as shrimp trawlers. It is achieved that shrimp in a continuous process can be landed in a shrimp trawler and subsequently cooked, peeled and packaged on the vessel and thus ready for sale to consumers as soon as the trawler is in port. The quality of the ready-to-eat peeled prawns will thereby be significantly higher than has hitherto been possible, and the production process will be optimized and thereby cheapened, partly because the entire shrimp processing process is assembled on the fishing vessel landing the prawns and because the ripening process and processing time are minimized. This also provides a better quality of the peeled shrimp.
    The shrimp pellet machine can of course also be used for shrimp piling on land. In a further convenient embodiment, the actuating element comprises two toothed belts - a first toothed belt and a second toothed belt - which toothed belts are driven by a first motor assembly and the first toothed belt drives the first rollers and the second toothed belt drives the second rollers.
    By having two separate toothed belts to drive the first rollers and the second rollers respectively, wear on the toothed belt surfaces is distributed on two separate toothed belts. In addition, it may be easier to mount two belts instead of just one toothed belt, simply passing each one over a pair of drive rollers in the two end regions, and moreover being driven by the servo motor, which in a separate toothed belt drive drives the drive rollers. The rollers are driven synchronously and thus have the same surface / peripheral speed via the different gear sizes and diameters on the rollers.
    Each first roller has a first gear having a tooth with a plurality of teeth t1, and every second roller has a second gear having a tooth with a plurality of teeth t2, which teeth on the gears and diameters of the rollers are arranged so that the peripheral speed of rotation of the rollers are the same when the gears are engaged with the toothed belt (s). It is assumed here that the teeth of the two teeth are uniform.
    Hereby the optimum mutual rotational relationship of the first rollers and the second rollers is obtained so that one of the third rollers can be operated by simultaneous contact via shrimp shell parts with the surface of one of the first rollers and one of the second rollers. In a further convenient embodiment, the diameter D1 is smaller than the diameter D2 and the number of teeth t1 is less than the number of teeth t2. A suitable value for D1 is 63.5 mm and for t1 20 teeth; while a suitable value for D2 is 76mm and for t2 24 teeth. The small roller / cylindrical roller or third roller has a diameter D3 of 12 mm. In a further convenient embodiment, the gears are engaged with the toothed belt (s) in the pillar region and the gears are arranged so as not to touch each other. The gears do not touch each other at any point during the entire shrimp pellet process.
    Since the gears that lie next to the rollers are not rotatably connected to the first, second and third rollers, respectively, the rollers rotate as the gears rotate. Since the gears are not engaged with each other at all during the entire chain propulsion and also in the pellet area, limited wear on the rollers is obtained, since the first, second and third rollers are thus only moving relative to each other in the pellet area, as a result of the gears. is driven round the pillar area by the toothed belt (s). In a further convenient embodiment, the first motor assembly is a servo drive which can be programmed for any propulsion of the toothed belt (s) at which the first and second rollers rotate to move the surfaces opposite to each other in the range of 10 degrees to infinity in one direction and in the interval 10. degrees to infinity in the opposite direction, preferably in the range of 20 degrees to 30,000 degrees, and more preferably in the range of 180 to 20,000 30 degrees. The third roller can be operated synchronously or asynchronously with the first and second rollers. The degrees indicated must be understood as continuous revolutions, with 360 degrees being a full revolution. Thus, for example, 30,000 degrees will be the same as 83 1/3 full turns in the same direction. An infinite number of degrees thus corresponds to continuous operation in the same orbital direction.
    Hereby the processing of the shrimp can be regulated and the machine can be set to the optimum in terms of rotation of the rollers as a function of the size and degree of ripening of the shrimp. In a further convenient embodiment, the rollers have a metallic or polymeric surface and the first and second rollers have a polymeric surface and the third rollers have a metallic surface. The shrimp are peeled by friction between the activated rollers and the released shells are collected under the chain in the space between the pellet area of the chain and the return flow. In a further convenient embodiment, the chain is arranged to move continuously and the first and second rollers in the pellet area are arranged to rotate in changing directions. In a further convenient embodiment, the third rollers are positioned between the first rollers and the second rollers and are at a spring or the like which pushes the third rollers towards the first and second rollers and so that the upwardly facing surfaces of the first rollers are tangents to a first common plane and the upwardly facing surfaces of the second rollers are tangents. to a second common plane, and that the first plane in the pillar area is vertically above the second plane. If the third rollers do not have their own drive, it is assumed that the gap is filled with peel and shell parts from shrimp during shelling, so that a torque is nevertheless transferred to the third rolls from the rotation of the first and second rolls. In a further convenient embodiment, the shaving pellet machine comprises a cleaning station, which cleaning station is located below the pellet area. In a further convenient embodiment, the first face of the attack and the second face of attack is the same face.
    This is the case when there is only one toothed belt, where a particular surface of the toothed belt will be the one having abutment against both the first gear and the second gear for operating the first rollers and the second rollers. Of course, it will only be a time shift from the time when the first surface engages with the first rollers gear and the time when the same surface engages with the second rollers tooth and thus goes into the second surface. In a further convenient embodiment, the first attack surface is different from the second attack surface. This is the case when the machine comprises separate toothed belts for driving the first gears and the second gears respectively. In a further convenient embodiment, the toothed belts / toothed belt are driven by toothed belt gears. In a further convenient embodiment, the gears which drive the cylindrical rollers are mounted on a shaft which extends along the axis of rotation of a cylindrical roller.
    Generally, it should be stated about the invention that it uses less water, namely about 75% less than the known machines.
    The quality of the shrimp is better by using the present invention compared to the machines on the market, since there is less dilution of the shrimp since they do not mature artificially to the extent of the use of the known machines.
    The variable speed on the chain and on the rotation of the rollers means accurate pellet grade and greater yield of 1.5-2% compared to the traditional shrimp piling.
    Wear of the rollers is more even as wear occurs on the entire surface. The toothed belt system is very easy to clean.
    The rollers are cleaned in the area during the pellet process, which is why the rollers are always clean and no downtime is needed.
    The invention will now be explained in more detail with reference to the drawing, in which:

    FIG. 9 is a sectional view through the rollers of the shrimp pellet machine of FIG. 7 with an enlarged section of the rollers.
    FIG. 1 shows a section of a shaving pellet machine 1 according to the invention. It comprises a closed chain 3 consisting of a plurality of joints comprising cylindrical rollers 4,5,6. The 4.5.6 longitudinal axis of the cylindrical rollers is 90 degrees relative to a shaving pellet direction 7. The rollers comprise first rollers 4 of diameter D1 and second rollers 5 of diameter D2 as well as third rollers 6 of diameter D3. The rollers have a metallic or polymeric surface, the first 4 and the second rollers 5 having a polymeric surface and the third rollers 6 having a metallic surface. The rollers 4, 5, 6 are positioned relative to each other such that the third rollers 6 are positioned between the first rollers 4 and the second rollers 5. In a spring (not shown), the third rollers 6 are pressed against the first 4 and the second rollers 5, however, the third rollers 6 are mounted thus that they do not come into contact with the first and second rollers, but maintain a clearance relative to each of the other two adjacent rollers. Thus, when rotating the first 4 and the second rollers 5, the third roll 6 spins around if shrimp parts are clamped between the rollers. The first rollers 4 form a first plane and the second rollers 5 form a second plane and the first plane in a pellet area 8 - ie. the area of the machine where the shrimp is peeled - is located vertically above the second plane. The first 4 and the second rollers 5 rotate in the pellet area 8 by means of an actuating element 9 driven by a first programmable motor assembly 10 in the form of a programmable servomotor. Another motor assembly 11 drives the closed chain 3 in the shrimp pellet direction 7.
    The actuating element 9 comprises a toothed belt 12 and in the example shown two toothed belts: a first toothed belt 17 and a second toothed belt 18. The first toothed belt 17 has a first attacking surface 13 and the second toothed belt 18 has a second attacking surface 14. First attacking surface 13 is with first means 15 in the form of a first gear 19 in engagement with the first roller 4, the first contact surface 13 being grooved and by friction driving the gears around. Thus, the gears are not pivotally connected to the rollers, so the rotation of the gears is transferred directly to the roller. Second attack surface 14 is engaged by second means 16 in the form of a second gear 20 with the second roll 5. The power transfer is the same as for the first rollers 4. The first 4 and the second rolls 5 have a peripheral velocity vector which is opposite to each other where the roll surfaces are closest. on eachother. The gears are mounted on the same axis around which the rollers rotate, but a gear and the roller to which it is connected are firmly connected to each other. The first gear 19 has a tooth with a number of teeth t1 and the second gear 20 has a tooth with a number of teeth t2. of the second gear 20 is connected to a second roller 5. The number and diameter of the teeth of the rollers are arranged such that the peripheral speed of the rollers 4,5 is the same when the gears 19,20 are engaged with the gears / gears 12,17. 18th
    The first motor unit 10 shown is a servo drive which can be programmed for any propulsion of the toothed belt (s) 12,17,18, at which the first 4 and the second rollers 5 rotate, and thus have opposite peripheral speeds where they are closest to each other, but the same direction of rotation, so that they are all clockwise or all clockwise.
    The toothed belts are each tensioned out between two drive rollers 27 located at each end of the shrimp pellet area.
    The rotation of the rollers can be anything in the range of 10 degrees to infinity in one direction and in the range of 10 degrees to infinity in the opposite direction. Preferably, the rotation is in the range of 20 degrees to 10,000 degrees. At the rotations, the third roll 6 rotates in the shrimp pellet area 8. The changing direction of rotation is indicated by the arrow I.
    Since the third rollers 6 are driven by both the first and second rollers 5, they ideally have the same circumferential velocity as the first and second rollers, each of them contacts, but in the opposite direction of rotation. The third rollers 6 are raised so that their surfaces do not touch the surfaces of the first or second rollers, but they are driven indirectly when shrimp shell parts are squeezed between the third rollers and adjacent first or second rolls. The chain 3 is arranged to move forward continuously and the first 4 and the second rollers 5 in the pile region 8 are arranged to rotate in alternating directions. As mentioned, during the rotations, the third rollers 6 spin around if there is material between the rollers to transmit the movement.
    FIG. 2 shows a section of the chain used to peel or peel shrimp. It shows the first rollers 4 lying in one plane and the second roll lying in a vertically displaced plane relative to the first rollers. In between, the third roller is disposed, the third rollers spinning round when there are traveling parts between the rollers and in this case the third roller 6 or roller will run up against the large rollers 4,5 or rollers, so that surface speed is the same. Since the three rollers / rollers have different diameters (preferably: ø76.5; ø63.5; ø12) the number of revolutions is not the same. The small ø12 roller with ø12 thus runs ø76.5 / ø12 = 6.37 times more turns than the first roll 4.
    The described combination of alternating diameters and surfaces of the incoming rollers 4,5,6 has been found to be optimal in terms of peeling or peel shrimp effectively. A shrimp pellet process is followed by the chain 3 being driven in a direction of rotation, as indicated by arrow 7, where shrimp to be peeled, the chain 3 is applied at the top at the inlet to the horizontal inlet. The shrimps are subsequently peeled off by friction through contact with rollers 4,5,6 driven by the actuating element 9.
    The released shrimp shells are collected under the chain 3 and the shelled shrimp can be collected at the end of the chain 3 at the horizontal outlet.
    When installing the shrimp pellet machine in shrimp trawlers, the shrimp pellet process can be optimized by speed adjustment of the second motor assembly 11 driving the chain 3 back and forth as well as by the speed adjustment of the first motor assembly 10 (and thus the toothed belt (s)) driving the cylindrical rollers 4,5.
    The further embodiment of the shrimp pellet machine shown in Figures 3, 4, 5 and 6 will then be explained in detail. FIG. 3 shows that the third rollers 6 in the pellet area 8 are rotated by a further activating element 30; 30.1; 30.2 arranged for operating a first set 6.1 of the third rollers 6 in a first direction of rotation, and wherein the actuating element 30; 30.1; 30.2; is also arranged for operating a second set 6.2 of the third rollers 6 in a different and opposite direction of rotation.
    As also seen in FIG. 3 is repeated in the closed chain 3 the following sequence of rolls 4,5,6 all the way around the chain: one of the first rolls 4, one of the first set 6.1 of the third rollers 6, one of the second rolls 5, one of the second set 6.2 of the third rolls 6, such that two consecutive of the third rollers 6 along the chain in the shrimp pellet area are always of the additional actuating element 30.1; 30.2 is operated in opposite directions. Driving directions for the toothed belts are indicated by arrows 30.4 in FIG. 3. At the far right of FIG. 3 is a side view from the left where all the drive wheels 6.3 on the third rollers 6 outside the single link 3.1 of the chain are shown, and as can be seen, the drive wheels 6.3 connected to the third rollers 6 are mounted directly on extensions of the longitudinal axes of the third rollers 6 with respect to the closed chain 3 joints. The first set 6.1 and the second set 6.2 of the extended axes of the third rollers 6 each have their own extension on which the drive wheels 6.3 are mounted, so that the first and second sets of the third wheels drive wheels 6.3 sit along two straight parallel lines along the closed chain 3 in the pillar area. Hereby, the actuating element can be designed as two parallel running belts 30.1; 30.2 in the same plane, each operating its set 6.1; 6.2 of the third rollers 6.
    As seen in FIG. 4 and FIG. 6, the additional actuating element comprises a drive wheel 31 which drives a closed drive belt 30 with external and internal drive surfaces, the movement of the two drive surfaces being transmitted to the first and second sets of the third rollers 6, respectively, via a drive wheel coupled to each third roller 6.3. The drive wheels 6.3 of the third rollers 6 are made up of gears, the first set 6.1 and the second set 6.2 of the mounted gears of the third rollers being driven by their respective toothed belt 30.1,30.2, the one toothed belt 30.1 being in driving communication with the outside of the closed driving belt 30 via gear wheel 35, and simple belt drive coupled thereto 36, and the second timing belt 30.2 is in driving communication with the inner side of the closed drive belt via gear 37.
    The drive wheel 31 grips your internal tooth on the closed tooth or drive belt 30 and runs counterclockwise as shown by the arrow mark in FIG. Similarly, the gear 37, which is also in driving engagement with the internal tooth of the closed drive belt 30, runs counterclockwise, and this direction of rotation is retained on the tooth belt 30.2 driven by a gear which sits on the same axis as the wheel 37.
    The outer tooth of the closed tooth or drive belt 30 contacts the gear 35 and this wheel then runs clockwise. Likewise, the belt drive 36 connected to the gear wheel 35 runs clockwise and this movement is transmitted to the gear belt 30.1, which consequently runs clockwise at the direction of rotation of the drive wheel 31.
    The drive belt 30 is driven by a servo pull 38 so that its speed and direction of rotation are controllable.
    As shown in FIG. 5, a brush roll 50 is arranged at the area 41 just before the shrimp is supplied, which can, by rotation, help to clean the first, second and third rollers.
    It is part of the invention that the shrimp pellet machine 1 is mounted and operated in maritime vessels such as shrimp trawlers.
    The invention provides that shrimp in a continuous process can be landed in a shrimp trawler and subsequently cooked, peeled and packaged on the vessel and thus ready for sale to consumers as soon as the trawler is in port. The quality of the ready-to-eat peeled prawns will thereby be significantly higher than previously possible, and the production process will be optimized and thereby cheapened, partly because the entire shrimp processing process is assembled on the fishing vessel landing the prawns.
    The shrimp pellet machine can of course also be used on land and installed in buildings. In FIG. 7 and an alternative arrangement of the rolls 4,5,6 which is shown here with inclined center axes. Here, the idea is that the shrimp are fed to the rollers' surfaces at the high side 42, and the pre-peeled shrimps leave the plant at the low side 43, as the shrimp progressively descends along the sloping rollers. The first, second and third rollers may have drives as shown in FIG. 8, and the drives may be independent of each other as explained above.
    The rollers are illustrated in FIG. 9, and here it is seen in the enlarged section that they are arranged in the usual manner, with first rollers 4 at the top, second rollers 5 in a lower plane and the third rollers 6 between the first and second rollers. Here, too, the third rollers 6 are slightly raised so that there is clearance between the surfaces of the third rollers 6 against both the first rollers 4 and the second rollers 5.
    The propellants shown for the rollers are suitable, but of course it is possible to drive the rollers individually with, for example, stepper motors. For rollers mounted on a chain arrangement as described above, power supply becomes a challenge, but for rollers that are sloped and fixed in a frame, stepper motors are an option.
