  • Patent number: 9011953
    Abstract: The invention concerns a process for the treatment of heat-sensative fluid food products (P) in a UHT system (1), particularly dairy such as milk, cream, milk protein concentrate. The invention has the task, in a UHT system whose basic structure using an infusion chamber is described in [4], of ensuring an equal and constant dwell time as well as an equal and constant temperature trend for the entire treated food product downstream of an outlet of a mechanism in which the food product is subjected to direct heating by the introduction of steam, and to minimize fouling during heat maintenance of the food product in this area. This is achieved using process technology in that: The heated food product (P*) upstream of its heat main undergoes a predetermined pressure increase (?p) at a predetermined, unchanging location, and The pressure level upstream of the location before the relief lies above the pressure upstream of the location before the pressure increase (?p) (FIG. 1).

  • 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: 6474225
    Abstract: A number of cheese block forming towers are fed curds from a central vat. Curd accumulates in each tower and its weight causes whey to be expressed. Individual blocks are severed from the bottoms of the columns of curd by guillotine blades. A controller monitors both the output of each severing device (rate of discharge of blocks and their weight) and the rate of use of curd in each tower. The latter is determined by the same time that the level of curd takes to drop from sensor to sensor. These factors may then be used to adjust the output of severing devices or the charge rate of curd to balance the outputs of the multiple tower.

  • Patent number: 5655440
    Abstract: An apparatus and method for manufacturing mozzarella cheese. Cheese curd is cooked and stretched in a heated water bath (2), augers (3) mounted therein transporting the curd therethrough to an outlet (8). The outlet (8) conjoins with a conduit (7), controlled by valves (9), to provide a pressurized supply of curd to a bank of fill-heads (10). Each fill-head (10) includes two volumetric metering compartments (13) which provide a dual discharge at an outlet (12) thereof. Hoops (14) are placed at the outlets (12) to be charged from the fill-heads (10). A hoop (14) can have a divider (19) inserted therein to divide the hoop (14) into two compartments (20 and 21) corresponding to those of the fill-heads (10). Before charging plastic liner bags (50) are placed in each hoop (14) or hoop compartment (20 and 21) as appropriate. The liners (50) are subsequently vacuum sealed and then immersed while in their loops (14) in a cooling bath (32).

  • Patent number: 5630361
    Abstract: The present invention provides a plurality of two piece wear buttons that insert into the blade of a guillotine and protect the surface of the guillotine as it slide in U-shaped channels within a cheese block forming unit. Each wear button comprises a male portion and a female portion, each portion configured to fit into opposite sides of a through bore drilled in the surface of the guillotine blade. The male portion is provided with an outwardly tapered extension or neck which snaps into an inwardly tapered recess defined within a cylindrical member on the female portion of the button. Each portion is also provided with a lip such that when the male portion and the female portion are joined together within the through bore, the lips overlay the through bore and inhibits product from seeping into the through bore.

  • Patent number: 5572925
    Abstract: Multiple columns of cheese curd are simultaneously compressed and cut into blocks of cheese by feeding curd into the top perforated tubular linings hanging freely within hollow towers, all towers positioned on a single, enclosed sanitary housing. A negative pressure is maintained in each tower to draw curd into the tower. Each pillar of curd is supported by a single guillotine blade closing off the bottom of all the towers and located within the sanitary housing. Each perforated, freely hanging lining is spaced apart from the wall of its tower to form a drainage passage for whey pressed out from the curd by the weight of the superimposed pillar. The guillotine blade is then withdrawn and each pillar of curd is lowered by an elevator into a cheese form positioned below each tower and within the housing. The guillotine blade is then returned to its closed position, so as to cut off a block of curd from each pillar.

  • Patent number: 5544571
    Abstract: Sterilizing apparatus and a method including a stepped transition heat exchange bank is used to raise the temperature of an incoming fluent food product before introducing the fluent food product to a sterilizing chamber in which the fluent food product is discharged in the form of a free-falling film; sterilizing steam is injected into the sterilizing chamber, all of which is absorbed by the fluent food product; from the sterilizing chamber, the food product with absorbed steam is passed to a vacuum chamber where part of the water in the fluent food product flashes to steam again and is removed for subsequent processing through heat exchangers and recirculation back to a steam generator upstream of the sterilizing chamber. The food product from the vacuum chamber is passed to a stepped heat exchange bank before passing to storage or packaging facilities.

  • Patent number: 5443857
    Abstract: A method of sterilizing a liquid milk based product comprises indirect preheating of the product and final heating to a sterilization temperature 140.degree.-150.degree. C. by direct steam injection. The product is cooled by so called flash-cooling at which steam corresponding to the added amount of steam is evaporated. The product is cooled by indirect cooling. It is now proposed that the product prior to the flash-cooling is cooled from the sterilization temperature 140.degree.-150.degree. C. to a temperature in the interval 90.degree.-120.degree. C. in an indirect, first cooling step after which the product is cooled by flash-cooling to a temperature of 70.degree.-85.degree. C. The apparatus for sterilization comprises a balance vessel (1) connected to an indirectly working first heat exchanger (4) for heating of the milk based product. A steam injection nozzle (6) is arranged in a pipe line out from the heat exchanger (4).

  • Patent number: 5404802
    Abstract: A cheese formation tower wherein cheese curds and attendant whey are introduced into the upper portion of a vertical, low friction material lined, tower and the whey is extracted through gravitational, differential pressure/relative vacuum and vibration techniques. As the material reaches the lower portion of the tower the whey has been substantially extracted to provide the formed cheese product. A guillotine or cutting arrangement is provided to cut the formed cheese to suitable lengths which are then extracted from the tower. The invention is particularly directed to cheese units of various shapes and sizes but preferably smaller than the standard, 11".times.14", 40# block. The unit includes cleaning means for cleansing of the entire unit following complete batch formation. The tower ensures satisfactory whey removal and the delivery of properly formed cheeses.

  • Patent number: 5209943
    Abstract: A method of making bulk cheese utilizes a vertical tower wherein the curd and whey mixture is introduced at the top of the tower and the cheese is withdrawn from the bottom of the tower. The tower is placed under negative pressure by drawing a vacuum through the center of the tower along its central axis and along the periphery of the tower to draw whey from the curd and whey mixture toward the center of the tower and toward the perimeter of the tower to remove it from the curd as the cheese is formed.
