  • Patent number: 4418616
    Abstract: An apparatus for pressing and draining whey from cheese curd particles in manufacturing large sized blocks of cheese. Cheese curd is placed into a pressing container mold which has a removable internal draining means having dimple-like projections maintaining a space between the plates of the screen. In one embodiment of the invention, pressure is applied in a vertical direction on the curd particles uniformly draining the whey. The drain means is extracted, and a second application of pressure closes remaining interstitial voids. In a second embodiment of the invention, a first application of pressure is applied to the curd particles in two separate directions at the same time. A spreading spade is inserted between substantially vertical parallel foraminous plates thereby moving these plates further apart exerting a relatively horizontal force on the curd particles and, in conjunction, a press plate pushes down on the curd particles exerting a relatively vertical force on the curd particles.

  • Patent number: 4334465
    Abstract: A method and apparatus for processing and packaging cheese in which cheese curd which has been milled and salted is fed into four columns mounted on an upright tubular trunk fitted at the lower end with a guillotine blade movable between a closed position in which it closes the bottom of the trunk and an open position in which the blade is wholly clear of the trunk. The columns are maintained at a sub-atmospheric pressure so that air in the curd is flashed off immediately the curd enters the columns. The curd in the columns flows into the trunk and merges with the curd from the other columns to form a pillar of curd supported on the guillotine blade. The walls of the columns are perforated for drainage of whey pressed out from the curd by the weight of superimposed curd. An elevator below the trunk lowers the pillar of curd when the guillotine blade is withdrawn, the blade being subsequently returned to cut off a block of cheese from the lower end of the pillar.

  • Patent number: 4300445
    Abstract: An apparatus for separating curd fines from whey including a closed housing having an inlet to receive whey that contains a substantial portion of curd fines. The whey is introduced onto an inclined delivery trough and is discharged from the lower end of the trough onto a stationary inclined screen which is inclined in the opposite direction from the delivery trough. In passing from the delivery trough to the screen the whey passes through a slot which distributes the whey in a thin layer over the screen. In flowing down the screen a portion of the whey drains through the screen and is collected in a whey bin, while the remaining portion of the whey and fines, in the form of a slurry, is collected in a separate bin and can be returned to the cheese making vat.

  • Patent number: 4291064
    Abstract: A method of pressing and draining whey from cheese curd. In particular, this method is made suitable for producing large blocks of cheese. A container mold having an internal drain screen is filled with cheese curd particles. Pressure is then applied to the cheese curd draining whey into the drain screen and out of the container mold. The container mold is then inverted and the internal drain screen is removed and another application of pressure is used to close any remaining voids within the cheese curd. The container mold is then sealed and prepared for shipping.

  • Patent number: 4289793
    Abstract: Large blocks of cheese are formed in a container having a removable bottom, side walls, and an essentially open top. A plurality of upstanding perforated tapered posts extend from the removable bottom to essentially the desired final height of the cheese block. The posts are longitudinally and laterally spaced from one another so that the curd surrounds each post when the container is filled with curd. Pressure is then applied downward to the curd in the container which compacts the curd and causes draining of whey through the upstanding perforated posts. After the curd has been compacted to the desired height, and the whey has been drained through the upstanding perforated posts, the container is inverted and the tapered posts are withdrawn. Pressure is again applied to cause the curd surrounding each perforated post to knit together and aid in removal of any additional whey, thereby providing a cheese block of uniform texture.

  • Patent number: 4237781
    Abstract: Crumbled cheese curd is fed into the top of a hollow perforated column in a chamber maintained at a sub-atmospheric pressure so as to form in the column a pillar of curd devoid of air pockets, the curd in the lower portion of the pillar being compressed by the weight of superimposed curd to press out whey therefrom and consolidate the curd, the whey passing through the perforations in the wall of the column, and the pillar of curd is repeatedly lowered, the bottom end of the pillar severed to form a block of cheese, and fresh curd added to the top of the pillar. During the lowering of the pillar of curd, the gaseous pressure in the space between the column and the wall of the chamber is increased so as to effect a transverse compression of the pillar of curd and thereby reduce the frictional sliding resistance between the pillar of curd and the column.

  • Patent number: 4224865
    Abstract: A process and apparatus for the continuous manufacture of cheese starting with the ultrafiltration retentate of milk or a milk product until the solids content is approximately that of the desired cheese. Additional constituents such as fat are added so that the resulting cheese precursor or precheese has solids content and fat to solids ratio substantially the same as the desired cheese. The cheese precursor is heated and mixed with rennet. The rate of flow of this mixture into a coagulation cylinder is controlled so that the flow in the coagulation cylinder is laminar throughout. The temperature of the cylinder wall is maintained slightly below that of entering mixture so as to obtain, in equilibrium, the formation of a coagulation front which is substantially plane and at right angles to the axis of the coagulation cylinder, thereby homogenizing the texture of the resulting curd. The cylinder cross section is approximately that of the desired cheese.

  • Patent number: 4217818
    Abstract: An apparatus for the continuous matting and milling of cheese curd. The apparatus includes a housing which houses an upper, water-permeable, endless conveyor belt and a lower endless conveyor belt which operates in the opposite direction to that of the first belt. A mixture of cheese curd and whey is deposited as a layer on the upper belt and the whey is drained through the belt and is discharged through the lower end of the housing. The matted curd is transferred from the upper belt to the lower belt and as a result is inverted, and is subsequently discharged to a curd milling unit which acts to cut the mat of curd into cube-like chunks.

  • Patent number: 4157680
    Abstract: A perforated drainage plate for use as a lining in a cheese mould has parallel strips punched out of the plane of the plate to one side thereof to form two narrow slots on each side of each strip with the ends of the strips merging smoothly into the undeformed part of the plate. The plate is arranged with the strips abutting against the wall of the mould so that a narrow passageway is formed between the undeformed portion of the plate and the wall of the mould for draining away when forced through the slots. The strips are aligned in the direction in which a cheese block slides out of the mould after removal therefrom. The angle of inclination of the ends of the strips relative to the adjacent portion of the plate does not exceed 30 degrees, the width of the slots does not exceed 0.6 mm, and the radius of curvature of the recessed surfaces of each strip is not less than 1 mm.

  • Patent number: 4018145
    Abstract: An apparatus for draining whey from cheese curd. The cheese curd to be treated is contained within an open ended box or container and the lower end of the box is enclosed by a support plate while the upper end of the box is enclosed by a perforated lid. The support plate is provided with a plurality of drain holes and is also formed with a series of downwardly extending grooves which extend from the interior of the plate to the peripheral edge. The grooves are generally V-shaped in cross section and have a greater depth than width. During vacuum draining of the cheese curd, the whey is drained through the holes in the support plate as well as along the grooves to thereby provide improved drainage characteristics for the mass of cheese curd.
