    (54) INSTALLATION FOR STERILIZATION OF FOOD PRODUCTS CONTAINED IN PACKAGING.
    FIG. one; in fig. 3 is the same general view in the direction of the arrow P in FIG. 4; FIG. 4 is a top view of the cover of the sealed chamber; Fig, 5 - part of Fig, 2 with a different position of the working bodies; FIG. 6 is a section 111-111 of FIG. 2 (enlarged);
    An installation for sterilizing food products (FIGS. 1 and 2) consists of a hermetic sterilization chamber 1, an additional chamber 2 connected to the sterilization chamber 1 with the help of the shutter 3, a belt conveyor 4 with a web 5 feeding the can 6, filled with the product, to be sterilized, and a second conveyor belt 7 serving to unload the sealed cans 8 after sterilizing the product with which they are filled.
    The hermetic sterilization chamber 1 includes a housing 9 mounted on legs 10 and a hermetic cover 1I, it is made of steel capable of withstanding pressures up to 3 kg / cm, as well as a vacuum. On the cover there are two windows 12, pressure sensor 13, temperature sensor 14, pressure gauge 15, decompression. a manually operated valve 16 and an automatic safety valve 17,
    Inside the housing 9 there is a circular feed plate 18, driven by a vertical shaft 19 mounted in a sealed bearing 20 mounted in the bottom of the camera body just under the center of the plate 18, the fixed guide 21 serving to accumulate the cans to be sterilized and having a spiral shape, angled 22, 23 and 24 on the ledges 25, 26, 27, 28 and 29 inside the chamber. Plate 18 can be brought into slow motion by a motor with gear 30 via a chain drive 31, linking gear 32 mounted on shaft 33 at the output of the motor gearbox, and gear 34 mounted on the bottom surface of a vertical shaft 19 that passes through the bottom of the chamber sealed bearing 20
    A side tube 35 is mounted on the housing 9 of the chamber, extending in a horizontal direction and having a flange 36. Inside the coarse there is a small horizontal plate 37,
    serving to feed the cans and driven by the vertical shaft 38, B1} being in a sealed bearing 39, the chain drive chain 31 passes
    also through gear 40, which it leads to movement simultaneously with plate 18,
    The shutter 3 is one of its flanges 41 attached to the flange 36 of the pipe 35
    a sealed chamber using a plate 42 having an opening 43 of the same cross section as the gate opening so as to pass the cans, the shutter 44, 44 is rigidly connected to the screw 45, the flywheel 46 is necessary for manually operating the peak, to the other flange 47 of the shutter 3 is attached the end face of the tunnel 2, the guide 21 of the plate 18 has an extension 48 over the plate 37, an extension 49 in the gate 3, an extension 50 along the conveyor 4, an extension 51 in d; an additional chamber 2 and an extension 52 along the conveyor 7, inside the additional chamber 2
    there is an endless conveyor 53 which can move either in the direction fg or in the opposite direction f with the aid of a motor with a gearbox (rte shown) for feeding the ba
    It is to be sterilized from the feeding conveyor belt 4 to the distribution plate 37 and, conversely, from this plate to the output conveyor belt 7. The upper part of the conveyor 53 is horizontally at the same level as the distribution plate and the feeding and output conveyors. In Fig, 1 and 2, the conveyor 53 is shown in the working position, that is, e. it connects the distribution plate area and the area of the inlet and outlet conveyors. However, at the time of processing the cans, it is necessary to temporarily isolate the chamber, for which the shutter 3 is closed. In this connection, the conveyor 53 is designed so that it can be removed from the shutter 3 (Fig. 5). For this purpose, the upper active conveyor belt is supported by two gears 54 and 55, the axes of which 56 and 57 are mounted on the sections of the ends of the two plates 58 and 59, and the proximal ends of these plates are connected by pins 60 and 61 to the ends of two intermediate plates 62 and 63, the other two ends of which are connected by common the studs 64. The plate 59 is fixed, while the plate 58 {equipped with a control knob, not shown in the drawing) can move along the additional chamber 2y carried along by the conveyor 53, which as a result of this takes either a working position (FIG. 2) j or the inoperative position (Fig. 5) due to the presence of a hinge joint, formed by two intermediate plates 62 and 63, connecting the movable plate 58 and the fixed plate -59. In the unfolded position, this traction is held by means of a pin 65 (Fig. 6), which is pulled out directly under the Intermediate plate 63 from the fixed guide 66 and is held in the extended position with the help of the spring 67. With the help of a button-68 fixed on the pin 65 , you can pull the pin overcoming the spring resistance and release the intermediate plate 63, which under the action of its own weight and the weight of the other intermediate plate 62 deflects down the pin 60, resulting in a fracture of the thrust formed by the pl astinas 62 and 63. A plate 69 welded to the lower surface of the intermediate plate extends beyond the hinge 64 and abuts the lower surface of the intermediate plate 62 so as to prevent the extension of the thrust above the horizontal position. Dp provide tensioning of the conveyor 53 even in the case when its upper belt has a small length corresponding to the non-working position of the conveyor (Fig. 5), the conveyor passes through two fixed rollers 70 and 71 and a movable roller 72 fixed to the end of the lever 73, which can move downward on a fixed horizontal axis 74. The amplitude of the movement of the lever in the upper direction of the fire. It is trimmed with the help of an adjusting screw 75. The axis of the roller 70 is at the same time the driving shaft of the conveyor and is connected to the output shaft of the motor with a gearbox (not shown). One end of the conveyor 53 is located in the additional chamber 2 exactly opposite the feed belt conveyor 4, where there is also a concave plate 76, which can occupy either the position indicated by a solid line for feeding the cans to be sterilized from the feed belt conveyor 4 to the conveyor 53, or the position shown by dotted line 76a for passing sterilized cans from the conveyor 53 on the belt conveyor 4, which delivers them to the can sealing machine. This device includes a device 77 for removing sterilized cans, attachment tool 78 for overlaying a canister, device 79 for rolling in a can, and device 80 for feeding sealed cans to an output conveyor belt 7. These four tools are serviced by a rotating disk 81 driven in a rotational direction in the direction indicated by the arrow f, with the help of a motor with a gearbox 82 through a transmission device (not shown). Fig. 3 shows a vacuum unit 83 driven by an electric motor 84 and communicating with the internal volume of the chamber 1 by means of a nozzle. 85, two valves 86, 87, the inlets of which are connected to the tube 88, respectively, are associated with the device for supplying pressurized water and the tube 89 / associated with the device for supplying steam, and the outlet ports are connected by means of a socket 90 that communicates with the internal volume of chamber 1 through a circular pipe 91, (FIG. 2), valve C (FIG. 3) isolating DOG during sterilization to avoid damage by steam, and valve O feeding the pump with cold water. FIG. Figure 2 also shows the cuttings 92, associated with the tube 93 serving as a hot steam supply in the additional chamber 2, a check valve 94 and two drain valves A and B. The installation works as follows. After the cans 6 are filled with the product. (For example, carrots without adding water), the cans arrive at the feeding conveyor belt 4 (Fig. 1), which is constantly moving in the direction indicated by the continuous path. arrow f. The concave plate 76 guides the conveyor plate to the conveyor 53, which in this case moves in the direction indicated by the continuous arrow fj and is fully fold, in the reversed position, the passage is inside. open gate 3 and reaching the distribution plate 37, on which the cans arrive. The cans then go to a large plate 18, where, due to the spiral guide 21, they accumulate. During this cycle phase, the rotating plates 37 and 18 rotate in the directions indicated by the continuous arrows f and fj, respectively, while through the openings of the valve 94 (figure 2) and valve 87 (figure 3) into the tunnel and the sealed chamber 1, steam is supplied at a low pressure in order to prevent the penetration of bacteria into the tunnel and the chamber.
    As soon as the large plate 18 is filled with cans, the conveyor 53 extends out of the shutter 3, which closes. The valve 87 of the steam inlet to the chamber 1 is then closed, and the valve 86 is opened to introduce some water into the chamber so as to condense the steam therein. Vacuum pump 83 (FIG. 3) is operated to provide about 700 mm Hg inside the vacuum chamber. Depending on the nature of the product to be sterilized, the vacuum is maintained from 2 to 10 minutes, after which the vacuum is broken by opening the valve 16 located on the chamber flap (Fig. 4) and through the valve 87 (Fig. 3, steam is supplied to the chamber. for a certain time, the temperature in the chamber rises to the level required for sterilization. Then, the steam inlet valve 87 closes and the pressure in the chamber decreases during the time determined in a practical way, which is most often 5 minutes. As soon as the pressure in the chamber decreases to the atmospheric level, heated steam is introduced into the chamber through valve 87 in order to create a slight overpressure as in the case of cans feeding into the chamber.Then, the shutter 3 opens, the conveyor 53 unfolds and the plates 18 and 37 are opened begin to rotate in the opposite direction, i.e. in the direction indicated by the intermittent arrows ff and f. The conveyor 53 also moves in the opposite direction
    those. the direction indicated by the broken arrow fj. . Sterilized jars are made on the plates 18 and 37 and on the additional chamber 2 the same way, only in the opposite direction. Since the swivel plate is now in position 76a, the cans from conveyor 53 enter the output conveyor belt 4, pass between the guides 51 and enter the device for sealing and rolling the lid, from where they are fed to the output conveyor belt 7 in the direction indicated by the arrow fg . In addition, in the additional chamber 2, a slight excess pressure is increasingly maintained by means of heated steam, so that the banks are in an aseptic atmosphere until they are sealed.
    The pressure sensor 13 is not an absolutely necessary instrument and can be used, if necessary, to attach laboratory instruments to it.
    The advantages of the proposed installation include the fact that it makes it possible to fill the packaging with product without adding juice or brine there, as a result of which the product does not liquefy. The sterilization process takes place with open packaging, into which heat can directly penetrate, which makes it possible to reduce the sterilization time compared to classical methods by about eight tenths. Packing is sealed in a heated steam atmosphere that is completely aseptic.
    If it is necessary to replace the air in the cans with some neutral gas (for example, nitrogen oxide, at the end of the sterilization process, after decompression of the chamber, a vacuum is created again, using a vacuum pump. Then gas is introduced into the chamber until the pressure in the chamber reaches atmospheric pressure. Thereafter, a slight overpressure of the heated vapor is created in the installation and the cans are removed from the installation, as described above.
