Definitions

  • the present invention relates to screw presses for extracting liquid from fruits or vegetables or the like, and more particularly to a screw press for extracting the remainder of the liquids in such fruits and vegetables after predraining or pre pressing.
  • Screw presses have been widely used for the extraction of liquids from solids or semi-solids in the food industry, A primary application of such presses is in the grape and wine industry.
  • Our copending International Patent Application Serial NO. PCT 4581-00613 is for a screw press which may be utilized as a predrainer for removing free run juice from destemmed grapes.
  • the disclosed predrainer press will advantageously remove about 80% of the available juice from the grape must. Thus, the must from the predrainer is relatively dry.
  • Prior art screw presses have difficulty in handling, very dry materials. Most such screw presses utilize a large forward pitch feed and pressing screw extending for approximately half the length of the press barrel. The remainder of the barrel is open with a closed door disposed at its outer end.
  • the door construction disclosed in this patent has the disadvantage of not being readily adjustable.
  • the operator of a press must be able to control the back pressure of the door if various types of fruit and materials are to be completely dewatered.
  • the barrel and the feed screw must be cleaned.
  • the feed screw, feed screw drive shaft, and the door are mounted on a carriage such that the feed screw may be completely withdrawn from the barrel for cleaning. This arrangement is relatively complex and expensive.
  • the present invention is a screw press type liquid extractor especially adapted for final pressing of predrained grapes, and similar fruit
  • the screw press represents an improvement over the screw press section of the Hunt U.S. Patent No, 4,117,776.
  • the press utilizes an elongate cylindrical barrel or cage divided into a feed and pressure section and a pressing chamber section.
  • the walls of the pressing chamber section and of a portion of the feed and pressure section are formed from a filter screen or the like through, which extracted liquids can pass.
  • the feed and compression screw is formed from a cylindrical body having large pitch spiral threads attached thereto and disposed in the feed and pressure seotion of the press barrel, A. concentric drive shaft through the screw body is utilized to turn the feed screw via a hydraulic drive unit.
  • the front portion of the feed and pressure section is an enclosed inlet region with an inlet opening at the top thereof to allow gravity feed of materials into the press.
  • a circular door is disposed at the end of the pressing chamber, having tapered edges mating with an opening in the chamber and bulkhead.
  • the circular door is slidably engaged with the feed and pressure screw drive shaft which extends through the door and is supported at its outer end by a bearing frame or pillow block. External inward pressure on the door will therefore maintain the door tightly closed until outward pressure from inside the chamber overcomes the external pressure and forces the door to slide rearward along the drive shaft.
  • a novel hydraulic pressure system is utilized having hydraulic actuators attached to the rear frame of the press with their actuating rods applying pressure to the rear door through, a throw-out type bearing assembly. Hydraulic pressure is applied to the hydraulic actuator pistons in a direction to force the rods outward.
  • An adjustable pressure relief valve is connected between the inlet and outlet lines of the hydraulic actuators settable to relieve at a selected pressure above that applied to the actuators.
  • the door also includes a plurality of cutter bars attached and projecting from its inside surface. As the door is opened by the internal pressure, a clutch switch is mechanically closed causing an electric clutch anchored to the drive shaft and to the door to engage, rotating the door at the speed of the drive shaft. The cutters then pare away the compressed plug or log which, builds up in the pressing section during operation, allowing the chips to be collected and carried away.
  • the material to be dewatered is introduced into the inlet opening of the press and into the first flight of the feed screw.
  • the incoming material is quickly carried along the feed screw, which, may be rotating at 5 to 60 rpm, and into the pressing chamber.
  • the inlet is designed to prevent slippage of the incoming materials and the feed screw can quickly fill the pressing chamber.
  • additional material forced rearward will begin compressing the material forming a plug or cake in the pressing section.
  • the pressure squeezes the liquid from the material which liquid passes through the screens and is collected in pans beneath, the screw press.
  • the pressure produced by the feed screw continues to build up with liquids being squeezed from the cake by both, the wiping action of the face of the screw threads against the cake and the compression of the material within the cake.
  • the pressure increases to the point that the rear door is forced rearward against the hydraulic pressure, engaging the clutch, the rotation of the rear door with its cutter blades turning at the same rotational speed as the screw feed will continuously pare away the cake, allowing incoming material to replace the ejected portion. This action will be continuous as long as the inlet is maintained with a sufficient head of material.
  • the dryness of the ejected cake which is indicative of the percentage of remaining liquid removed from the incoming material, is controlled by the pressure at which the rear door opens, and is thus controllable by the operator through adjustment of the hydraulic pressure.
  • Such pressures can be predetermined for various types of materials to be pressed.
  • the pressure may also be controlled by the rate of rotation of the feed screw, providing an additional variable to optimize the throughput for specific material.
  • the rate of rotation is also adjusted to maintain a desired head of material in a hopper above the inlet opening.
  • the screen of the mesh may be selected to provide some filtering action with respect to solids, however, a tendency of solids to clog the screens must be avoided. It is also important after a run to be able to easily and efficiently clean the filter screens. Additionally, it is desirable to be able to change filter screens for the optimum filter mesh design for the variety of grape or the type of fruit being processed.
  • the filter screens of the invention comprise a pair of semi-circular sections of a cylindrical cage having a screen frame consisting of a plurality of circumferential ribs arranged to support the screens,
  • the screen frames thus represent halves of a cylinder with attachment strips along the outer edges.
  • a pivot shaft is disposed parallel with the drive shaft of the feed screw having a series of interleaved hinge blocks. pivoted thereto.
  • the two cage sections are attached at the bottom to the interleaved hinge blocks which form offset hinges such that opening of the two screen cage sections causes the sections to move downward and outward, completely clear of the feed screw.
  • the screen halves are normally secured at the top when the unit is in operation. When cleaning is required, the bolts holding the top edges of the screen sections together are removed and the two halves opened.
  • the preferred drive system for the invention utilizes a hydraulic system powered from an electric motor.
  • the drive motor for the feed screw is therefore a hydraulic unit with control of the hydraulic pressure utilized to provide speed control.
  • the electric motor serves only to operate the hydraulic pump to provide hydraulic pressure.
  • the hydraulic motor transfers this energy at constant torque regardless of the speed.
  • the hydraulic system also furnishes pressure for the end door pressure assembly.
  • Figure 1 is a cross-sectional view of the frame of the invention showing the feed and pressure screw and the pressing chamber, with details of the clutch and hydraulic pressure assembly omitted;
  • Figure 2 is a partial perspective view of the screw press showing one filter screen cage section in its normal operating position via a cutaway view and another cage section in its open position for cleaning or changing of screens;
  • Figure 3 is a lateral cross-sectional view of the filter screen cage showing its open position in phantom view and the rear door with projecting cutters;
  • Figure 4 is a top view of the door pressure system with the pressing chamber shown in cross- sectional view;
  • Figure 5 is a schematic diagram of the hydraulic door pressure system and clutch system; and Figure 6 is a greatly simplified schematic diagram of the power system of the invention,
  • the framework of the screw press consists of four transverse bulkheads mounted on a bed or base 5: front bulkhead 10 having a front bearing 11 mounted therethrough for shaft 26; rear bulkhead 14 having a tapered opening 13; inlet bulkhead 17 utilized to support inlet housing 32 between front bulkhead 10 and inlet bulkhead 17; and intermediate bulkhead 12 provided between inlet bulkhead 17 and rear bulkhead 14 serving to divide a cage section shown generally at 40 into a front feed section 51 and a rear pressing chamber 45, Cage section 40 is formed by screen frames 41 Csee Figure 2). consisting of a series of circumferential ribs 49 supporting stainless steel screens 42 which form the inner walls of cage 40, Details of the.
  • the essentially cylindrical inlet housing 32 and cage section 40. form an elongated cylinder housing a feed and,pressure screw shown generally at 20,
  • Screw 20 consists of a cylindrical base or body portion 22 mounted to and concentric with, drive shaft 26 as may be noted in Figure 3.
  • Spiral threads 24 are affixed to the surface of body portion 22 and have an outside diameter with sufficient clearance to turn within the walls of the cage 40 and inlet housing 32 without interference therewith.
  • the pitch and diameter of spiral threads 24, the diameter of body portion 22, and the length of the press are parameters which may be selected in accordance with the material to be pressed, the characteristics of the liquids to be expressed, the volumes of material to be handled, and the throughput required.
  • a 30 centimeters pitch feed screw for final pressing of grapes and similar fruit and an overall length of 2.4384 meters for the press barrel.
  • about 3-1/2 threads are present in the feed portion of the cage with, about the same length of cage for the pressing chamber portion.
  • This ratio of feed length to pressing chamber length particularly effective.
  • a rear circular door 16 having tapered edges fits tapered opening 13 of rear bulkhead 14. As described in more detail below, external pressure is utilized to hold door 16 closed against the pressure created by feed and pressure screw 20.
  • stainless steel covers 56 are used over bulkheads 17, 12 and 14, extending down and connecting to base 5 to prevent loss of liquids and to direct such liquids into pan 54, As the liquid is removed from the material and the pressure increases, door 16 will open as indicated by arrows D, causing the remainder to be extruded through the opening 13 in rear bulkhead 14 and ultimately into collector 52 for disposal as shown by solid arrows F in Figure 5.
  • Feed and pressure screw 20 is driven via shaft 26 from a hydraulic drive unit 60 which includes a manually variable speed conrrol indicated at 62.
  • rotational speed of feed screw 20 is a design parameter and may be selected in accordance with, the materials to be pressed and the desired throughput, we prefer to utilize a range of 5 to 60 rpm which is eminently suitable for extracting juice from grapes.
  • inlet section 32 and inlet throat 30 In accordance with our invention, the longitudinal length of the opening of inlet throat 30 is limited to not more than 1,5 times the pitch of spiral screw threads 24, and it is also necessary that inlet housing 32 enclose the lower portion of threads 24 to at least half of their circumference. For most applications, however, we prefer about 75% of the circumference enclosed.
  • shaft 26 projects through bushing 19. extending rearward and supported in bearing 13 in rear frame 25. Thus, shaft 26 can rotate with respect to door 16. With no material present in the press, door 16 is maintained in the closed position by a hydraulic system 70 omitted from Figure 1 but shown in top view of Figure 4.
  • Door 16 includes a rearward projecting drive tube 84 having a coupling to throw-out bearing assembly 80 and slots 85 engaged with, clutch tube 82 by pins 83.
  • Throw-out bearing assembly may include thrust roller bearings and ball bearings 81 (best seen in the cross-sectional view of Figure 11, As shown in Figure 4, hydraulic actuators 72 are mounted on rear frame 25 with their actuator rods 71 attached to throw-out bearing 80.

  • Fig-ure 5 a simplified schematic diagram of the hydraulic pressure and clutch system is shown with door 16 in its open position.
  • Cake pressure P C has exceeded hydraulic pressure P H , valve 94 has relieved, allowing door 16 to move outward, and switch arm 87 has closed switch 86, Magnet coils 92 in electrical clutch 90 are energized causing door 16 to rotate in the direction of A as indicated by the arrows.
  • Cake 100 is extruded out and its face chipped away by cutters 18 as shown by solid arrows F.
  • This speed is predetermined for particular varieties of grapes such that the ejected must at F ( Figure 5) has been pressed to achieve a practical dryness representing essentially all of the usable juice.
  • the required speed of rotation is also affected by the must head in hopper 50. If insufficient head is present, difficulty is encountered in maintaining positive feed. Therefore, it is desirable to have a flow rate from the predrainer sufficient to mainta.in an optimum head. If the velocity is too high such that the head is lost, only partial feed ing occurs, and the flights are not completely filled. Thus, the must will travel rapidly through the press, will be only partially pressed, and will be ejected with excessive juice remaining. As may be seen, the operator can readily maintain the predrainer at its optimum throughput by observing the head in hopper 50 and adjusting speed control 62 to compensate for variations in the head.
  • the operator may run feed and pressure screw 20 at high, speed to more quickly fill the pressing chamber and produce the required cake.
  • a feed screw pitch of 30 centimeters and a press length of about 2.4384 meters we have been able to build the cake in about five minutes.
  • the chamber is full, continuing feed compresses the must into a hard, firm cake forcing the remaining juices outward through, screens 42 between ribs 49. which. is then connected in pan 54.
  • all of the interior of the feed and pressure screw 20 region of the press is effective in dejuicing the must.
  • the must after leaving the first feed flight is pressed or squeezed as it is being forced by the screw 20 against the screens and the cake.
  • New must is being fed from the inlet throuch the relatively small volume of the screw flights to replace the slower moving cake material.
  • the cake is forced out of the rear door 16 mainly by the wipe or thrust of the pitch of the last screw flight. As the must in the screw thread flights also becomes packed, a wiping action between the screw faces and the cake occurs, greatly assisting in expression of the juice.
  • the projection of blades 18 may be 3.81 centimeters or less depending on the material to be pressed with 1.27 centimeters being preferred for pressing of most grapes.
  • clutch 90 engages causing door 16 to rotate with shaft 26.
  • Cutter blades 18 therefore act against the extruding cake to pare or crumble away the dry material which is allowed to drop into collector 52 as waste material.
  • additional cake is extruded and more must enters inlet 30..
  • the cperation is essentially continuous.
  • the operator may vary the feed screw drive speed within limits to assure a head is maintained in the inlet hopper 50. Periodically, the ejected must may be tested for dryness. As may be recognized, an optimum throughput versus remaining liquid may be determined experimentally for various types or varieties of grapes, the optimum pressures and feed rates noted for future use.

Abstract

Presse hélicoïdale pour l'extraction de liquides à partir de matériaux tels que fruits, végétaux ou analogues, possédant un corps cylindrique (51, 45) possédant une vis hélicoïdale concentrique à vitesse variable d'alimentation et de compression (20). La partie postérieure du corps cylindrique comprend une section de cage possédant des écrans de filtres perforés (40) pour le passage des liquides extraits et le filtrage des solides superflus du matériau pressé, ces écrans étant formés par au moins une paire de cadres (41) ouverts semi-circulaires possédant une pluralité de nervures (49) qui supportent des écrans de filtres remplaçables (42). La paire de cadres est fixée à un ensemble de blocs inférieurs de charnières (46) et est reliée de manière démontable le long des bords supérieurs des cadres (43). Les cadres peuvent être séparés aux bords supérieurs pour s'ouvrir comme un livre et se dégager totalement de la vis d'alimentation et de compression, de manière à permettre le nettoyage des écrans et de la vis ou le remplacement des écrans. Une partie du corps vers l'arrière de la vis d'alimentation et de compression forme une chambre cylindrique de presse (45) possédant des parois d'écrans pour le passage au travers de celles-ci des liquides extraits. L'extrémité de sortie de la chambre cylindrique de presse est fermée par une porte circulaire (16) possédant des barres de couteaux en saillie vers l'intérieur et montées de manière coulissante sur l'arbre d'entraînement (26) de la vis d'alimentation et de compression. Des dispositifs hydrauliques d'actionnement (72) appliquent une pression réglable à la surface extérieure de la porte. La pression interne du matériau provoque l'ouverture de la porte pour l'éjection du matériau séché. Un embrayage (90) est automatiquement en prise lorsque la porte s'ouvre pour tourner la porte et les barres de couteaux afin d'enlever un gâteau du matériau séché.
