     EXTRACTOR FOR THE PRODUCTION OF FRUIT PULP DESCRIPTION Field of the Invention This invention relates to the processing of fruit and, more especially, to a system and method for processing fruit to control the quality of the pulp.  5 State of the invention Citrus pulp is a type of fruit pulp.  Citrus pulp is typically separated from juice by processing citrus pulp in a juice extractor, which filters most seeds and membrane through a filter tube to produce citrus pulp and juice.  In addition, this juice produced is typically processed in a juice finishing machine to separate citrus pulp from juice.  It may be desirable in some cases to produce a larger pulp bag in an improved pulp system by recovering the pulp bags that are more intact.  For example, this citrus pulp can be added back to the juice to form a final product, that is, a pulpy orange juice, or the citrus pulp can be collected separately, cleaned and pasteurized, and sent to customers who pack their own juice or a juice-based product, or sell citrus pulp wholesale.  FMC, the predecessor of the assignee of the present invention, John Bean, Technologies 20 Corporation, offers a citrus juice and a pulp extractor that includes a first and second cuvettes that can be moved relatively to compress a fruit in between during extraction.  The extractor includes a first blade associated with the first bowl, and a second blade associated with the second bowl.  In addition, the extractor includes a filter tube that is coupled to the second cuvette to receive in it the pulp and juice.  As described in patent U. S No. 4. 376 409 the filter tube includes two sets of round holes of different sizes in the filter tube.  The holes closest to the upper end of the filter tube are smaller than the holes closest to the lower end of the tube.  The larger holes are typically of a size of 0.15 cm (0.060 inches) but are described as if they were as large as 0.32 cm (0.125 inches).   In some commercially used FMC extractors, the filter tube has a plurality of relatively large slotted openings.  In particular, the filter tube has an overall length of 26.34 cm (10.37 inches) and includes four groups of slotted openings that extend longitudinally in a smooth-walled tube having an external diameter of 2.99 cm (1.176 cm) inches).  Each group includes ten 5 slotted openings evenly separated.  Also, each slotted opening has a width of 0.32 cm (0.125 inches).  The slotted openings closest to the upper end have a length of 1.91 cm (0.75 inches).  The other three groups of slotted openings have a length of 3.02 cm (1,188 inches).  Although pulp of a larger size is produced, this filter tube also produces a relatively large amount of defects, especially with the membrane and core material, which requires additional disposal processing, and which causes the juice to be More bitter than desired.  A typical current extractor includes a filter tube with a plurality of round openings.  Each round opening actually has two diameters, the smallest diameter being the innermost radially.  This diameter is 0.16 cm (0.062 inches).  Attempts have been made to reduce defects downstream of the extractor.  For example, the U. S No. 6. 727 452 assigned to the assignee of the present invention, discloses a system and method that eliminates citrus pulp defects.  A feed mechanism advances the citrus pulp along a predetermined path of displacement within an inspection zone.  A camera for citrus pulp is located in the inspection area and acquires images of citrus pulp.  A processor connects to the chamber for citrus pulp and receives the images, and processes the images to determine the defects within the citrus pulp.  A rejection mechanism rejects the flow of citrus pulp that is determined to be defective.  However, there is a desire to produce larger pieces of pulp with a reduced amount of pulp defects.  Description of the invention In view of the foregoing background, it is therefore an object of the invention to provide an extractor and associated methods that improve the quality of the pulp in terms of a larger pulp size and / or a reduction in the number of defects   These and other objects, features and advantages are provided by an extractor comprising a first and second cuvettes that can be moved relatively together to compress a fruit in between.  The extractor has a first blade attached to the first bucket.  This first blade is cylindrical, and has a base with at least one peripheral opening disposed between adjacent peripheral portions 5 consisting of L-shaped support plates, and a first cutting blade extending externally to the base, following said base and coaxial with it.  The first blade comprises an inner core to said first and coaxial blade to it that extends from the base to the first cutting blade, being coaxially separated from said first cutting blade by an inner passage in communication with the peripheral opening of the base.  The first blade can also be called a blade with windows.  In addition, the extractor may also include a filter tube that engages in the second cuvette and has a plurality of grooved openings for the output of fruit and juice pulp.  The combination of the first blade with the slotted openings of the filter tube can considerably improve the quality of the pulp extracted.  15 For example, slotted openings can extend longitudinally.  Each of the slotted openings may have a width in a range of 0.76 to 1.27 mm (0.03 to 0.05 inches), and more preferably between 0.89 to 1.14 mm (0.035 to 0.045 inches).  Each of the slotted openings may have a length in a range of 1.78 to 3.81 cm (0.7 to 1.5 inches) in some embodiments.  Furthermore, the slotted openings 20 can be arranged in a plurality of longitudinally separated groups.  The filter tube may comprise a tubular body and a plurality of separate reinforcing rings that are coupled to the tubular body.  The reinforcement rings serve to reinforce the tubular body in strength and durability.  In some embodiments, the second cuvette may comprise an annular base that defines an inner wall, and a second plurality of fingers extending externally to the annular base, following it.  In addition, the second tray comprises a second blade which in turn includes a second cutting blade sized to be inserted into the inner passage of the first blade, and a flange that extends externally to the second cutting blade and mounts the second blade in the inner wall of the second bucket.  The flange may be aligned or above the adjacent inner portions of the annular base.  This arrangement also helps reduce pulp defects.   In some embodiments of the extractor, the filter tube as described may be used alone, without the first blades, or with the second blade and the second modified bowl.  The extractor can also include at least one juice finishing machine downstream of the filter tube.  Of course, other storage tanks, etc., can also be coupled downstream of the filter tube.  BRIEF DESCRIPTION OF THE FIGURES Figure 1 is a partial schematic and cross-sectional view of the portions of a juice extractor before compressing the fruit including downstream processing

embodiments of the invention are shown.  However, this invention can be carried out in different ways, and should not be construed as limited to the embodiments set forth herein.  Rather, these embodiments are provided so that this disclosure is thorough and complete, and conveys in detail the scope of the invention to those skilled in the art.  The same numbers always refer to the same elements, and premium notation is used to indicate similar elements in alternative embodiments.  Referring initially to Figures 1-2 and 5-6, a juice extractor system 15 according to the present invention is described.  Illustratively, the juice extractor system 15 includes a juice extractor 20 which, in turn, includes a first and second cuvettes 22, 24 between which a fruit 21 (for example, orange or grapefruit) can be introduced.  20 With the fruit in between, the first and second cuvettes 22, 24 make a relative displacement with each other, approaching each other, illustratively, along, for example, a basically linear reciprocal path of the displacement.  The fruit peel is separated and the inner portions of the fruit are removed when the first and second cuvettes 22, 24 approach so as to compress the fruit 21 25 as will be readily understood by those skilled in the art.  Illustratively, the fruit is maintained in the second cuvette 24 with the first cuvette 22 descending into said second cuvette 24 and compressing said fruit 21.  Illustratively, a cam drive 31 connected to the first cuvette 22 via a drive connection 29 directs the first cuvette 22 linearly towards the second cuvette 24.  As will be readily appreciated by those skilled in the art, other orientations of the first and second cuvettes 22 may alternatively be used, 24, as well as other mechanisms to move them in relation to each other.  For example, the first and second cuvettes 22, 24 can be oriented in the same horizontal plane, and each of them can move towards the other in a horizontal direction directed by one or several driving mechanisms known to those skilled in the art.  5 As further illustrated, the first cuvette 22 comprises a first plurality of fingers 23, and the second cuvette 24 comprises a second plurality of fingers 25.  Both pluralities of fingers 23, 25 house and compress the fruit 21 when the respective cuvettes 22, 24 come together.  Illustratively, the first plurality of fingers 23 extends radially to define within it a first inner wall of the cuvette 10 26.  A first blade 28 of the extractor - is housed inside the first cuvette 22, in the first inner wall of the cuvette 26, so that it is located within the upper part of the first cuvette 22.  The first blade 28 cuts a portion at the top of the fruit to allow separation of the fruit peel from the inside of the fruit.  15 As will be readily understood by those skilled in the art, this helps prevent fruit breakage 21 when squeezed between the respective pluralities of fingers 23, 25 of the first and second cuvettes 22, 24.  As can be seen in Figure 5, the first blade 28 is cylindrical and comprises a base 30 having three peripheral openings 32 arranged between 20 adjacent peripheral portions 40 of said base 30.  As will be readily appreciated by those skilled in the art, the first blade 28 may alternatively have more than three peripheral openings 32 in the base 30 or may have only one.  In addition, the first blade 28 has a first cutting blade 34 that extends externally to said base 30, following said base 30 and coaxial therewith.  Illustratively, the first cutting blade 25 has a cylindrical shape and a beveled cutting edge.  The first blade 28 includes an inner and coaxial core 38 to said first blade 28 extending from the base 30 to the first cutting blade 34, being coaxially separated from the first cutting blade 34 by an inner passage 36.  The inner passage 36, as shown, is in communication with the peripheral openings 32 of the base 30 and thus allows the release of fruit remains 21 therethrough.  The inner passage 36, through which the remains of fruit 21 are expelled or released as the skin of the fruit, it gives the first blade 28 distinct advantages over other blades that are typically used, which either have no openings or only have lateral openings.  In contrast to conventional blades, when the first blade 28 cuts the fruit 21, it is much less likely that the skin of the fruit 21 and other remains will be trapped or stuck in it.  On the contrary, under the pressure made by the first and second 5 cuvettes 22, 24 squeezing the fruit 21 between them, the remains of the fruit 21 are pushed along and out of the inner passage 36.  Specifically, if the first cuvette 22 is disposed on top of the second cuvette 24 and descends on the fruit 21, the resulting pressure forces the remains 27 up and out of the first blade 28 (as indicated by the arrows 27 in the Figure 2).  10 Illustratively, each of the peripheral openings 32 of the base 30 of the first blade 28 is disposed between adjacent peripheral portions 40 of the base 30, which consist of L-shaped support plates, so that said support plates in L-shape connect the base of the first blade 30 and the first cutting blade 34 together.  This consequently improves the release of debris through the inner passage 15.  Additionally, the first cutting blade 34 has three openings 42 arranged between the L-shaped support plates.  In addition, illustratively, each opening in the sheet 42 is in communication with one of the three peripheral openings 32 of the respective base, thus further improving the release of the remains through the inner passage 36.  20 Additionally, the first blade 28 may optionally include residue deflectors 44 adjacent to the base 30.  As illustrated, each debris deflector 44 has a pointed edge 46 that is directed towards the inner passage 36.  Debris deflector 44 as shown illustratively, is adjacent to the inner portion of the L-shaped support plate.  Fruit 21 is squeezed when the cam drive 31 directs the first tray 22 towards the second bowl 24.  The first blade 28 cuts a portion at the top of the fruit 21 when the first bowl 22 moves against the fruit 21.  The fruit 21 is also forced against a second cutting blade 56 disposed in the second tray 24, which cuts a lower portion in the lower part of fruit 21.  As a result of the increase in pressure during the extraction process, the inner portions of the fruit 21 are forced through the lower portion and into a tube filter 64 (or pre-finishing machine).  The separated fruit peel is discharged between the first bucket 22 and the first blade 28.  As detailed above, any fruit peel or debris from within the first blade 28 is released through the inner passage 36.  Illustratively, an axis 60 extends from the base of the first blade 30 opposite 5 to the first cutting blade 34.  The shaft 60 can secure the first blade 28 to the drive connection 29 which is connected to the drive mechanism of the cam 31 which illustratively directs the first bowl 22 down onto the fruit 21 during juice extraction.  This first blade 28 can be called a knife with windows in that it has windows that allow the remains of fruit 21 to be ejected through them.  When the inner portions of the fruit 21 are removed, they move into the filter tube 64.  When the extraction is completed, a tube with holes 66 moves upwards from below the filter tube 64 inside it, creating pressure on the contents thereof, which causes the juice extracted and the pulp to flow through slotted openings 64a, 64b of the tubular body 65 of the filter tube 64 and towards a juice collector 68.  The slotted openings 64a, 64b extend longitudinally, as shown in the illustrated embodiment.  This longitudinal arrangement is in contrast to the slotted openings disclosed in the U patent. S No. 6. 293 189 that reveals grooved openings that extend circumferentially.  The 20 circumferentially grooved openings are designed to fulfill a grid function and cause more defects while probably also damaging the pulp.  Each of the slotted openings 64a, 64b may have a width in a range of 0.76 mm (0.03 inches) to 1.27 mm (0.05 inches), and more preferably between 0.89 mm to 1.14 mm (0.035 to 0.045 inches).  For example, the width can be 1.02 mm (0.040 inches).  In some embodiments each of the slotted openings 64a, 64b may have a length in a range of 1.78 to 3.81 cm (0.7 to 1.5 inches).  For example, the length can be 2.80 cm (1.102 inches).  The slotted openings 64a, 64b can be arranged in a plurality of longitudinally spaced groups 30 as shown in the illustrated embodiment of Figures 1 and 2.  As shown with specific reference to Figure 1, the illustrated embodiment of the extraction system 15 includes a sorting finishing machine 80 that engages to collector 68 and generates waste 85, as well as fruit juice and a jet of pulp.  The fruit pulp and juice are pumped, by means of a pump 81, into a cyclone separator 82.  The upper outlet of the cyclone separator 82 is carried to a first finishing machine 84 which, in turn, generates useful or valid fruit pulp 87, as well as fruit juice 86, as will be appreciated by those skilled in the art. matter.  In addition, a second finishing machine 83 processes the material from the bottom outlet of the cyclone separator 82 to generate a stream of juice 86 as well as the waste pulp 88.  With further reference to Figures 3 and 4, another embodiment of the filter tube 64 'is now described.  The filter tube 64 'includes a tubular body 65' and a plurality of separate reinforcing rings 10 66a ', 66b' that are coupled to the upper end of the adjacent tubular body.  The rings 66a ', 66b' serve to reinforce the tubular body against probably higher pressures that can be experienced at the upper end, thereby providing greater longevity and durability.  Of course, in other embodiments, more than two reinforcing rings 66a ', 66b' 15 could be provided as will be appreciated by those skilled in the art.  The slotted openings 64a ', 64b', 64c ', 64d' may have the dimensions described above with respect to the filter tube 64 shown in Figures 1 and 2.  In this embodiment, there are 30 slotted openings in each group, and the successive groups are compensated through rotation with each other.  The outer diameter of the tubular body 20 'can be 2.99 cm (1.176 inches).  In addition, the higher slotted openings 64a 'may have a slightly shorter length, for example, 2.54 cm (1,000 inches), compared to the other slotted openings 64b', 64c ', 64d' which may have a length of 2.80 cm (1.102 inches) as noted above.  The combination of the first blade 28 with the slotted openings of the filter tube 64, 64 'can considerably improve the quality of the pulp extracted in terms of reducing effects, and increase the size of the pulp extracted.  In some embodiments, the extractor 20 may include only the slotted opening of the filter tube 64, 64 ', and yet it may achieve an acceptable increase in the quality of the pulp 30 as will be appreciated by those skilled in the art.  Referring now further to Figures 7-10, another aspect of the juice extractor 20 in relation to quality and production is now described.  Illustratively, the Second cuvette 24 comprises an annular base 50 defining an inner wall 52 and a second plurality of fingers 25 extending externally to the annular base 50, following it.  Illustratively, the second tray 24 also mounts a second blade 54 within the inner wall of the second bowl 52.  Illustratively, the second blade 54 includes a second cutting blade 56.  As perhaps best shown in Figure 10, the second cutting blade 56 is sized so that it can be inserted into the inner passage 36 of the first blade 28 during the extraction of the pulp from the fruit 21.  As also illustrated in Figure 8, the second blade 54 has a flange 58 that extends externally to the second cutting blade 56 to position the second blade 54 on the inner wall 52 of the second bowl 24.  In this regard, as shown in Figure 8, the flange 58 includes a first diagonal portion 58a and a vertical portion 58b that fits into the inner wall 52 of the second cuvette 24.  Illustratively, tab 58 is at an aligned level or above adjacent portions of the annular base 50.  As will be readily understood by those 15 skilled in the art, the tab 58 may also be arranged above the annular base 50.  The flange 58 serves to avoid cutting and separating the peel of the fruit 21, including the ring of the peel resulting from the cutting of portions of the fruit 21, of the mixture that remains of the inner portions that are squeezed from the fruit by the first and second cuvettes 22, 24.  Consequently, without reducing juice production, tab 20 58 improves the quality of the juice by decreasing the amount of peel oil that could otherwise be added to the juice during pressing.  The deflectors of the remains 44 that are optionally included in the first blade 28, which illustratively have pointed edges 46, can cooperate with the flange 58 by additional segmentation of the fruit peel 21 and its deflection away from the first cuvettes. and second 22, 24 and, therefore, far from the inner portions of fruit 21.  Again, the deviation of the peel ring away from the inner portions that are squeezed from the fruit 21, reduces the amount of peel oil in the juice that is ultimately produced, thereby improving the quality of juice without reduce juice production.  30 The release of the fruit peel and other remains through the inner passage 36 of the first blade 28 and its deflection by the flange 58 prevents the remains from mixing with the inner portions of the fruit 21.  Consequently, the quality of the juice extracted is superior.   The first cylindrical cutting blade 34 of the first blade 28 may have an internal diameter ID1, an external diameter OD1, and a wall thickness T1.  The second cylindrical cutting blade 56 of the second blade 54 may have an external diameter OD2 configured to be inserted into the internal diameter ID1 of the first cylindrical cutting blade 34, an internal diameter ID2 and a wall thickness T2.  The size of the particular component can be selected to produce a juice quality and a relatively high desired production.  The removal of the PC shell thickness measurement, for example, can be found in a convenient range for oranges.  This measurement of the shell thickness PC coincides with the gap between the outer diameter of the first cutting blade 34 and the inner diameter of the first cup 22.  Of course, other shell removal values may also be used as will be appreciated by those skilled in the art. .  In addition, the filter tube 64 and the tube with holes 66 as described above can also be appropriately sized for the second blade 54 as will be readily appreciated by those skilled in the art.  Applicants have now recognized unexpected improvements in pulp size and 15 in reducing defects by the use of slotted openings of filter tube 64, 64 ', either alone, or in combination with the first blade 28 , and the modifications in the second blade 54 and in the second tray 24.  It is noted that the first blade 28 and the modifications in the second blade 54 and in the second tray 24 are disclosed in the U patents. S Nos 6. 805 043 and 6. 923 112, assigned to this assignee and whose 20 contents are incorporated by reference in this document in its entirety.  The '043 and' 112 patents refer to improving the quality of the juice while maintaining a relatively high juice production by reducing fruit peel pieces that, in turn, introduce peel oil into the juice.  The use of the slotted openings of the filter tube 64, 64 'in combination with the first blade 28 and other modifications described herein, advantageously result in fewer shell defects, provide an increase in the size of the pulp, provide a production of finished juice equal or better, provide a production of pulp equal or better, and provide a quality of finished juice equal or better.  30 Turning now to the bar chart graph of Figure 11, a comparison of the pulp size distribution between a conventional puller (STD 062) and the puller as described herein (Option B), illustrates that a upper percentage of pulp is in a size range greater than 9 mm for an example in which oranges from Valencia are used.  The STD 062 extractor includes a typical filter as described in the background that has round openings of a diameter of 1.58 mm (0.062 inches), without a knife with windows, and slotted openings or modifications of the second bowl and the second blade as in the embodiment labeled Option B.  5 In particular, the percentage of pulp having a general dimension greater than 9 mm of the Option B extractor is 20%, while the STD 062 extractor produces only 13% of said desirable pulp sizes.  The percentage of pulp in the range of 5-9 mm is 39% for the Option B extractor and 33% for the STD 062 extractor; the percentage of pulp size of 2-5 mm is 33% for the 10 extractor of Option B and 43% for the extractor STD 062; and the percentage of pulp less than 2 mm is 8% for extractor B and 11% for extractor STD 062.  Consequently, it can be seen that for the most desirable pulp size, that is, larger than 9 mm, the Option B extractor provides a significant 20% advantage of the pulp that falls within that desirable range compared to only 13 % of the pulp of the STD 062 extractor.  Turning now to Figure 12, a pair of data points is represented that pertains to the percentage of relative pulp production and the relative defects in the pulp for Valencia oranges.  The origin or reference is for the prior art extractor STD 062 labeled as 391 3 "as described above, and in which the defect count is 191.  The data point for the Option B extractor shows a decrease in defects (84% reduction), and in relation, it also shows a reduction in the overall amount of finished pulp.  Accordingly, it can be seen that the advances disclosed in this document, especially, the slotted openings of the filter tube, alone or in combination with other features disclosed herein, provide a significant reduction in the number of defects ( Figure 12), and also provide an increase in the percentage of pulp that has a larger, more desirable size (Figure 11).  A person skilled in the art who benefits from the teachings presented in the previous 30 descriptions and in the associated figures will have many modifications and other embodiments of the invention.  Therefore, it should be understood that the invention is not limited to the specific embodiments disclosed, and that other modifications and embodiments are intended to be included within the scope of the attached claims.
