Patent number: 5082681Abstract: A curd and whey mixture is drained of loose whey on a conveyor and the dry curd fed into the top of a tubular perforated column (48,49) maintained under sub-atmospheric pressure to form a pillar of curd. A mass of curd severed from the lower end of the pillar is deposited in a mould (14) mounted on a turntable (13) rotatable to index the mould in succession at six pressing stations at each of which the curd is compressed for 45-120 seconds at a pressure of at least 4 bar in order to form a block of cheese with a rind firm enough to permit handling of the cheese block after ejection from the mould. At the first pressing station the curd is subjected to a sub-atmospheric pressure of -0.9 to -1.0 bar prior to compression. After the cheese block is ejected from the mould, the turntable returns the empty mould to the column for reception of another mass of curd.Type: GrantFiled: October 1, 1990Date of Patent: January 21, 1992Assignee: Alfa-Laval Cheese Systems LimitedInventors: Peter B.

Patent number: 4842869Abstract: A yeast trap device for use in making fermented beverages includes a trap container having a tapered neck portion through which a fluid conduit is inserted. A closure seal on the container neck provides an airtight seal around the fluid conduit. In use, a lower end of the fluid conduit is inserted into a container filled with a fermentable beverage mixture. The upper end of the conduit has a circumferential array of drain apertures spaced slightly below the upper open end of the conduit. The trap container has an open top portion which may be covered with cheesecloth or with a rigid airtight cover provided with a labyrinth airlock. During fermentation, yeast and contaminants are transmitted in a fluid suspension through the conduit and into the trap container. The carbon dioxide produced during fermentation exits through the open upper end of the conduit. Yeast and contaminant material are retained within the trap container and prevented from returning to the beverage mixture.Type: GrantFiled: June 10, 1988Date of Patent: June 27, 1989Inventor: Vincent Forino

Patent number: 4828865Abstract: A method for producing citrus juices with low final percentages of pulp. A centrifuge is used, with the space in the drum that receives the heavier phase, the phase with a high concentration of pulp, discontinusously emptied of at least some of the pulp through slide-activated extraction openings in the jacket of the drum. The light phase, the clarified juice, is continuously extracted. To ensure that the juice will be clarified considerably more effectively in the centrifuge at low energy and equipment costs, with the throughput increased incrementally, juice with a high concentration of pulp is continuously extracted from the centrifuge through channels or through an annular space that is demarcated on the inside by a large separating disk and that has an inflow opening at the largest inside diameter of the drum.Type: GrantFiled: June 12, 1987Date of Patent: May 9, 1989Assignee: Westfalia Separator AGInventors: Werner Kohlstette, Peter Schottler, Friedhelm Siegmann

Patent number: 4820540Abstract: Appparatus and method for continuously manufacturing cheese from cheese curd via mechanical means in which the curd is drained, matted and cheddared while carried upon a pair of conveyors running in opposite directions; milled and discharged upon a third conveyor, and sprayed while on the third conveyor at periodic intervals over a period of 12-20 minutes with a saturated water-based brine having a temperature of 80.degree. F. and pH of 5.1, the curd being permitted to rest undisturbed initially upon the third conveyor for a period of several minutes and being therafter agitated to distribute the brine more uniformly therethrough and being maintained throughout the process at a temperature of substantially 98.degree. F. Approximately eighteen (18) gallons of said brine is being uniformly sprayed upon each 1000 lbs. of curd.Type: GrantFiled: November 30, 1987Date of Patent: April 11, 1989Inventor: Burnell E. Budahn

Patent number: 4794013Abstract: A process and apparatus for extracting a liquid from a filtered residual substance, such as retentate resulting from an ultrafiltration during fining or clarification of raw juice from agricultural products. The residues are mixed with the expressed pomace in a separate processing and the mixture is subjected to a further juice extraction.Type: GrantFiled: July 9, 1987Date of Patent: December 27, 1988Assignee: Bucher-Guyer AGInventor: Walter Gresch

Patent number: 4774097Abstract: A centrifugal finisher and method of its operation are disclosed for separating finished juice from an initial juice including substantial solids or for separating finished fluid from any slurry including substantial solids, the slurry being introduced into one end of a cylindrical screen driven in rotation for centrifugally urging the slurry against the screen and causing a fluid component to pass through the screen. Wiper paddles are arranged on a support drum for rotation in wiping contact with the screen and for limited movement relative to the screen for continuously moving solid material from the slurry toward an outlet axial end of the screen.Type: GrantFiled: July 24, 1987Date of Patent: September 27, 1988Assignee: Brown International CorporationInventors: Ronald C. Bushman, William E. Harris, Jr.
