摘要:
An enclosed food processing device is provided having one or more conveyor belts and vertical agitators positioned above the belt. The agitators have forward and backward prongs that stir the food being processed without causing physical damage to it. The food enters the device through an inlet and is evenly distributed across a draining screen by an inlet deflector plate, which is adjustable to account for the different rates at which the food may flow into the device. Ramps are positioned under the device to collect liquid drained from the food, and the ramps have independent segments that separate the liquid based on the stage of the process at which it is drained from the food. A salting apparatus is provided for conveying salt to the food to be processed. The salt is dispensed in proportion to the amount of food to be salted. Salt is moved from a salt hopper into a chamber by a rotating dispensing wheel. The salting apparatus has a pump that moves a fluid, such as filtered air, through a Venturi pickup tee, where it creates a partial vacuum that pulls salt into the airstream from the chamber. The salt then is pushed through stationary salt distribution tubes and applied to the food to be salted.

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.
摘要:
Method and apparatus for separating liquids from soft particulate food solids, especially for cottage cheese. A tensioned belt is partially wrapped around a foraminous drum to compress a layer or bed of food particles advancing on the exterior of the drum wall through a separation zone beneath the belt. The belt run opposite the drum wall is free to flex and yield and to expand and contract the cross-sectional area of the separating zone, depending upon the thickness of the bed of food particles in said zone. Accordingly, delicate such particles will not be damaged or broken up into small particles, as would happen if a thick bed is forced through a zone of fixed cross-sectional area. Moreover, pressure is maintained on the bed when it is thin. A belt tightener is provided which will maintain a desired tension on the belt so that the belt will always exert a predetermined desired pressure on the bed. The input of the soft particulate food solids to the separating zone is optionally provided with a settling chamber so that large particles will settle to the bottom and function as a filter to intercept and inhibit loss of small particles through the drum perforations. Where used to dewater cottage cheese, the cheese curd is desirably creamed immediately after the dewatered curd leaves the separating zone and immediately after pressure has been removed from the curd. Accordingly, the curd is expanding while exposed to the cream, thus to facilitate and speed absorption of the cream by the expanding curd.

1,145,135. Separating curds and whey. McKENZIE & RIDLEY Ltd. 11 July, 1967 [11 July, 1966], No. 31953/67. Heading A2B. [Also in Division B1] A drainage filter for separating curds and whey in cheese-making comprises an endless moving filter band 5, made up of perforate stainless steel slats 7, and two fixed side walls 8 making sliding seals with the inclined upper run of band 5 to form a trough into whose lower end mixture is delivered (Fig. 1, not shown). The two runs of the band enclose a tray 4 which receives filtrate from the upwardly moving upper run, and another tray 3 is located below the lower run. Mixture on the upper run is stirred by radial arms 22 of electric beaters (20). Each slat 7 has an imperforate margin, and its long edges are bent over and slats joined by split pins. Slat ends are screwed to the links of endless chains (6) (Figs. 4-7, not shown), whose pivots incorporate rollers 6b bearing on tracks 12. Metal shoes 19 on slats 7 bear on polytetrafluoroethylene runners 17 to support the upper run. Band 5 is driven by electric motor (14) through a variable speed gear, and emergency stop buttons are distributed over the machine. Tube system (25) delivers hot water for cleaning the machine. Legs 2 are adjustable to vary the inclination of the band, which could be horizontal.
