Patent number: 4524139Abstract: This invention relates to a process and apparatus for the compressive regeneration of flexible, porous materials used as filter particles, oil-separating particles or carrier particles in a reactor. These materials are loaded in a reactor with a liquid containing substances to be removed. The liquid is, for example, water, and the substances are, for example, deposited solids, oil droplets or bacteria. After the flexible, porous materials become loaded with the substances, they are conducted to a press chamber equipped with a press means. The transporting, squeezing out, and separation of the water and substances from the flexible porous materials, as well as the recycling of the regenerated material into the reactor are achieved by either a one-time, or a repetitive to and fro movement, of the press means. This regeneration is accomplished with a single device which operates simultaneously as both a regenerating press and as a conveying installation.Type: GrantFiled: February 16, 1983Date of Patent: June 18, 1985Assignee: Linde AktiengesellschaftInventor: Uwe Fuchs

Patent number: 4509413Abstract: The present invention concerns a procedure for treating curd particles (10) produced in a cheese kettle, and a cheese mould (2) for applying the procedure, made of strainer sheet and provided with a separate cover part (4). The cheese mould (2) is placed in a tapping vat (1), where it separates the curd particles (10) tapped from the cheese kettle from the whey (9) accompanying them. It is essential in the invention that on the mould (2) is used a strainer-like cover part with which the mould is closed for the duration of curd particle tapping. By this expedient the necessity to level the curd particle surface before the subsequent pre-pressing step is avoided. In the pre-pressing, the strainer-like cover part (4) of the mould can be used, and the object of the pre-pressing step is to compact the particles into a cheese block that can be conveyed to further treatment.Type: GrantFiled: May 27, 1983Date of Patent: April 9, 1985Assignee: MKT-tehtaat OyInventors: Carl-Gustav Granberg, Heikki Kauppi

Patent number: 4125070Abstract: A press comprises a pressure roller of relatively large diameter cooperating with a plurality of satellite rollers, the material to be pressed passing between the pressure roller on the one hand and the plurality of satellite rollers on the other hand, each satellite roller having a lateral surface presenting a series of circular grooves, the bottom of the grooves being partially or completely empty to allow the squeezed-out liquid to pass.Type: GrantFiled: April 26, 1977Date of Patent: November 14, 1978Inventor: Rene J. Besnard

Patent number: 4121512Abstract: A water cylinder compacting and squeezing apparatus has a control valve requiring a connection of only one tube to the water cylinder for driving and retracting the piston in the cylinder. A water cylinder is mounted to a frame having a removable container and a compacting or squeezing portion connected to a piston rod so that the water cylinder can be connected to the household water supply for squeezing or compacting foods or other materials. A water flow control system includes a first valve for turning on the flow of water which is directed into the water cylinder for driving a piston. A second valve allows the water to flow to the drain and create a suction to draw the water from the cylinder to return the piston. Once the piston is returned, the first valve shuts off the flow of water.Type: GrantFiled: June 13, 1977Date of Patent: October 24, 1978Inventor: Joseph M. Valdespino

Patent number: 4113620Abstract: A press for removing liquid continuously from aqueous pulp comprises a cylindrical housing divided into an upper annular press chamber and a lower working chamber which are separated by a perforated de-watering disk. The press chamber is enclosed on its upper end by a varying height squeeze plate for varying the cross sectional area of the press chamber. The de-watering disk is carried on a rotatably driven shaft which is mounted centrally in the housing. The de-watering disk is configured for passing extensible blades, having a width equal to the width of the press chamber and slidably carried in holders which are joined to the de-watering disk and shaft. A cam which engages the blades is configured for varying the amount of extension of the blades continuously in a manner such that they extend into the press chamber into adjacency with the squeeze plate, substantially filling the press chamber at all times.Type: GrantFiled: October 26, 1976Date of Patent: September 12, 1978Inventor: Eigild S. Thomsen

Patent number: 4111110Abstract: A portable assembly for supporting stacks of cheese hoops in an inclined position from the vertical and including means for pressing the stacked hoops so as to press the whey therefrom and permit it to drain downwardly from one hoop to the other where it is collected by means of an inclined floor. The frame includes support members for removably but firmly holding the stacks of hoops as they are being pressed by cylinder and piston units located at the top of the assembly. Control means are provided for actuating the units in extending or contracting directions.Type: GrantFiled: June 6, 1977Date of Patent: September 5, 1978Assignee: Kusel Equipment CompanyInventor: Gary R. Smith

Patent number: 4111115Abstract: A continuous filter press of the type having wheels provided with conical screens and carried by pivoted side structures, the arrangement being such that material (e.g., a slurry) fed into the space between the wheels is carried through a pinch zone and then discharged. The claimed improvements to such presses include special means for journalling the wheels which employs a sleeve instead of a stud shaft, and material diverting means or plow which has portions on its inner end that are accommodated in central openings of the wheels.Type: GrantFiled: May 23, 1977Date of Patent: September 5, 1978Assignee: Bepex CorporationInventor: Charles E. Cory

Patent number: 4101285Abstract: Apparatus and methods for extracting juice from juice-laden material are disclosed. A tank system defines a row of material treating stations. A plurality of perforated baskets are swingably mounted at respective stations, each basket being operable to receive a charge of material. A flow of liquid is conducted through the stations in juice-extracting contact with the material. A basket actuating mechanism swings each basket from its associated station into a generally inverted position above the basket of a successive station to transfer the charge of material. In one preferred embodiment of the invention the basket is articulated intermediate its ends about a floating hinge. The basket actuating mechanism collapses the basket about the floating hinge to squeeze juice from the material before the material is delivered to the basket of a successive station.Type: GrantFiled: September 27, 1976Date of Patent: July 18, 1978Inventor: Sydney E. Tilby

Patent number: 4099458Abstract: A press, including a frame, a pair of rigid side structures, means for pivotally connecting the side structures to said frame, a pair of rotor assemblies having confronting faces arranged at an angle to each other and defining a pressing zone, each of the rotor assemblies being mounted for rotation in a respective side member, means interconnecting the side structures to one another and serving to apply yieldable force to urge the side structures toward one another, the improvements basically comprising means for adjusting the pivotal connecting means to vary the pressing action of the rotor assemblies, and a hydrostatic bearing means, which may be used in association with an annular thrust bearing, for minimizing the friction between the rotor assemblies and the side structures.Type: GrantFiled: April 5, 1976Date of Patent: July 11, 1978Assignee: The Black Clawson CompanyInventor: Peter Seifert
