  • Patent number: 10721872
    Abstract: A baling apparatus includes a housing having a fixed portion and a hinged door to release a bale, a series of rollers and belts for compressing and rotating baling material into a bale, a wrap feed mechanism for feeding a wrap around a bale, and means for compressing the bale during the baling operation. The instant baling apparatus may be used for materials that have traditionally been difficult to bale successfully, including small particulate such as mulch, and other materials such as common household trash. The baling apparatus may be utilized as a separate unit, or may be combined with a brush cutter/mulcher, or incorporated into trash removal equipment. A touch screen display and computer may be used in combination with sensors to monitor and control the baling operation, and a hydraulic system is used to drive the components.

  • Patent number: 10624369
    Abstract: A meat dewatering assembly (10) includes a support frame (12), a twin screw dewatering unit (14), a drive assembly (16) coupled with the unit (14), and a perforated housing (60). The unit (14) has a pair of tapered, non-parallel, intermeshed, helically flighted screws (52, 54) presenting nip clearances (59) between the fighting (55). The drive assembly (16) serves to counter-rotate the screws (52, 54). In use, emulsified meat is passed into the housing (60) during counter-rotation of the screws (52, 54), in order to compress the meat within the clearances (59) and thereby express water from the meat. Adjustment collars (38) permit selective size alteration of the nip clearances (59).

  • Publication number: 20020174780
    Abstract: A compressed gas, e.g. carbon dioxide, is injected under pressure into a press to increase the yield of oil from a natural material. The effect is brought about by the gas dissolving in the oil. The mass of gas required is typically less, often much less, than the mass of natural product.

  • Patent number: 6397739
    Abstract: A calendering method and calender in which a web material is passed through a calender, the calender nip being defined between a heatable hard roll and an endless, flexible and substantially non-compressible calendering belt. The heatable roll is heated in order to plasticize the surface layer of the web and the web is brought into contact with the heatable roll before the calendering of the web. After the preliminary contact of the web with the heatable roll a press treatment proper is applied to the web to be calendered in two stages. First a deformation is produced in the web in a press stage, after that the deformation that was produced is allowed to be reversed partially in a reversing stage and then a new deformation is produced in the web by pressing the web again in a finishing stage.

  • Patent number: 6264792
    Abstract: A method and apparatus for producing calendered paper by an on-line manufacturing system comprising at least a paper machine and a multi-nip calender. The method comprises following steps: removing water from a formed paper web by pressing, drying the pressed paper web by at least one dryer, calendering the dried web by the multi-nip calender, measuring a cross-machine moisture profile or a variable relative thereto, and altering the moisture of the web so that the moisture profile of the web in the cross-direction is even when the web enters the first nip of the calender.

  • Patent number: 6260481
    Abstract: A process and device for increasing the gloss and/or smoothness of a web of material are described, whereby a web of material (5) is passed through a roller gap where it is exposed to pressure. A steam dispensing device (7) is provided upstream of the roller gap relative to the direction of travel (9) of the web of material (5). The increase in gloss and/or smoothness is to be accomplished without consuming much energy. To do so, the steam is condensed on the web of material and the web of material (5) is guided through the roller gap before the increase in moisture content of the surface due to the steam treatment has dropped below a predetermined value.

    Abstract: A method for the treatment of a material web and a press arrangement with a plurality of press gaps. A roll has a flexible press jacket supported from an inside, and forms a respective press gap with each of at least two further driven rolls. The drive power, or speed of one of the driven rolls, is regulated in accordance with a predetermined desired value, to ensure a common speed of the driven roll. A maximum line force and/or drive power of a front press gap, considered in a web running direction, is controlled and/or regulated, at least within a certain range, in accordance with a maximum line force, or drive power, of a rear press gap, considered in the web running direction.

  • Patent number: 6070522
    Abstract: A transportable apparatus includes a housing with a door which opens to facilitate placement of trash within a trash receiving chamber of the apparatus. A sweep within the trash receiving chamber is actuated upon closing the door, forcing the deposited trash into a first compaction chamber, wherein the trash is mixed and compressed into a condensed mass by converging chamber walls and a downwardly directed spray of water released from high pressure nozzles at the top of the chamber. A reciprocating horizontal plate at the lower end of the first compaction chamber slices off a bottom layer of the mass of trash with each cycle of forward and rearward movement. The sliced layers of trash are pushed and compacted into a second compaction chamber until the second chamber is full. The trash is then compressed to form a composite unit of predetermined size and configuration.

  • Patent number: 5938895
    Abstract: A calender is provided for calendering a fibrous web wherein the moisture profile of the web can be controlled. The calender includes a plurality of rolls wherein at least one of the rolls comprises a profiling roll. The profiling roll has a plurality of profiling zones extending in a cross-machine direction to define a profiling nip. The roll is independently expandable in each of the zones, such as by an internal pressurized shoe arrangement, so that the pressure in the profiling nip can be varied in the cross-machine direction. A waterbox is positioned adjacent to the profiling nip and water is carried directly into the profiling nip where at least a portion of the water is transferred to the web such that the moisture profile of the web can be varied in the cross-machine direction by varying the nip pressure in the respective profiling zones.

  • Patent number: 5927188
    Abstract: A method and an apparatus for compressing hay such that the hay is suitable for long distance shipping. The hay is texturized by passing the hay through a shredder with an added fog or mist of water. The shredder separates, cuts and bends hay fibers rather than shattering the fibers. Compression of the hay is achieved by feeding the hay through an open ended compression conduit in a peristaltic manner through the use of a hydraulically actuated ram. Increased compression of the hay is achieved by applying transverse pressure to the hay as the hay travels longitudinally through the compression conduit.
