  • Patent number: 6942888
    Abstract: A cheese extruding machine and process for producing pieces of cheese of an exact weight directly from unaged or semi-aged cheese curds of semi-hard and hard cheeses. The cheese extruding machine includes a standard screw-type vacuum filler which receives large blocks of compressed curds, grinds the blocks into pieces, and compresses the curds into an airless, homogenous cheese flow without significantly damaging the curds. The cheese flow is forced through an elongate cheese forming tube of a desired cross-sectional shape for the cheese. A water jacket disposed about a second half of the cheese forming tube chills the periphery of the cheese flow to increase the firmness and maintain the shape of the cheese flow upon extrusion from the cheese forming tube. Frictional engagement between the cheese flow and the cheese forming tube produces back-pressure against the vacuum filler to maintain the cheese flow at a predetermined extrusion pressure and consistent density.

  • Patent number: 4510856
    Abstract: A method and apparatus for use in the manufacture of cheeses which proceed through a cheddaring stage. The method comprises treating a pre-drained and stirred cheese curd with a compressive and shear force so as to simultaneously expel the residual whey and permit fibrous development to occur in the fused curd. The apparatus for achieving this comprises a weighted shear assembly, such as a continuous belt overlying a portion of the conveyor belt upon which the cheese curd is conveyed in the direction indicated by the arrows. The cheese curd is subjected to compressive and shear forces as it passes beneath the continuous belt. The apparatus for prestirring the curd prior to passing under the continuous belt may comprise a plurality of adjustable position stirrers which move above the conveyor belt in the forward and reverse direction of the conveyor belt.

  • Patent number: 4509413
    Abstract: 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.

  • Patent number: 4485731
    Abstract: Buttermilk curd is continuously manufactured by heating whey in a tank to a temperature below that at which curd will form, preferably 75.degree. C., and pumping the heated whey to a treatment channel through a heating chamber in proximity thereto. The whey is further heated in the heating chamber to a temperature suitable for curd formation, preferably 85.degree. C., and is sprayed in the treatment chamber with a coagulant liquid, the resulting curd being swept along the channel by an endless blade conveyor to an endless band conveyor which conveys the curd to a discharge station. The apparatus disclosed includes two tanks to which whey is alternately supplied and in which the whey is heated to ensure a continuous supply of heated whey to the heating chamber. The whey from the heating chamber enters the treatment channel through a perforated partition in proximity to which are located spray nozzles for the coagulant liquid.

  • Patent number: 4393759
    Abstract: A cheese making apparatus comprises a rectangular vat, a pressing plate, a filtering sheet supported on the bottom wall of the vat for displacement in a longitudinal direction, and a transverse partition affixed to an end of the filter sheet adjacent a fixed end wall of the vat for simultaneous displacement with the filtering sheet in this direction. The partition defines with the side walls, the bottom wall and a mobile end wall opposite the fixed end wall an operating volume of the vat determining the amount of curds to be held in the vat for producing cheese from a pressed mass of the curds wherefrom the whey has been drained. Displacement of the partition changes the operating volume and the transverse partition is elastically compressible in a vertical direction whereby lowering of the pressing plate into the vat compresses the partition and permits the plate to apply pressure to the curds held in the vat.

    Abstract: A whey filter for removing fine curd particles from a stream of cheese whey includes a mesh screen (30) suspended in a cylindrical portion (17) of a tank (18) with cheese whey being introduced above the screen (30) through inlet ports (36) arranged to direct the cheese whey in a path tangential to the periphery of the circle of the screen (30). A plurality of scraper blades (38) rest on the screen (30) and are rotated by the flow of the cheese whey so as to urge the curd particles resting on top of the screen (30) toward a hole (44) in the center of the screen (30) so that the curd falls into an outlet chute (46) while the whey is removed from the bottom of the tank (18).

    Abstract: An apparatus for pressing and draining whey from cheese curd. In particular, this apparatus and method are 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: 4332831
    Abstract: A method and apparatus is disclosed for continuously producing salted cheese curd loaves by separating cheese curd from whey, blending salt with the separated curd in essentially the amount of salt desired in the final cheese being produced, forming the salted curd into a compacted outwardly tapered column and further separating whey from the curd, sequentially severing and discharging cheese curd loaves from the column, pressing the cheese curd loaves while in forms, immersing the pressed loaves into a brine solution for a time sufficient to form a rind on the loaves but insufficient to substantially alter the salt content of the loaves, and curing the rinded cheese curd loaves for a period of time required for the type of cheese being produced. This method shortens the brine curing time for hard cured cheese, and the method and apparatus enable semi-automated and continuous production of cheese curd loaves.

  • 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: 4232051
    Abstract: Liquid such as water or whey is removed from soft particulate food solids such as Cottage cheese curd utilizing a pressing belt for high speed gradual compression without significant damage to the food solids. This is accomplished by compressing the food solids in a variable cross-sectional area separation zone between a belt and a support surface such as a foraminous drum and regulating the cross-sectional area of the zone in response to changes in thickness of food solids in the zone to maintain substantially constant pressure of the belt on the food solids to avoid damaging pressure on the food solids. When the food is Cottage cheese curd, accelerated absorption of cream dressing can be obtained by adding the dressing to the curd after discharge from the separation zone before the curd completely expands from the compressed state so that the expanding curd sucks up the cream dressing as it expands.
