Abstract: A self-dumping separator having a vertical axis of rotation and having a drum (1) into which a disc stack (3) made up of a plurality of conical discs (4) is inserted, a centrifuge feed being introducible via an inlet pipe (6) and a distributor (7) into the centrifuge space (2), which is enclosed by the drum (1), at least two or more fins (17) being arranged in an annular solids space (15) that is arranged radially outside the disc stack (3), the clearance between the fins (17) and the inner wall of the drum (1) being at least three millimeters.

Abstract: 1. Method and Apparatus for the production of stearin from fat of animal or plant origin. 2.1 A method is carried out such that during the duration of a production run, a sharp separation between the stearin phase and the oil phase is maintained at a constant rate, to achieve an optimum quality of stearin and stearin yield. 2.2. Crystallized oil of a temperature from 10 C to 40 C is fed into inlet (12) of a nozzle-type centrifuge (11) which is not self-emptying and is equipped with a stack of plates (15) and a stationary gripping device (16) for the oil phase. The solid phase is guided through flow chambers tapering towards the nozzles (20) and discharged through these nozzles. To realize a high degree of separation between the stearin phase and the oil phase, the ratio between the feed rate in I/h and the nozzle capacity in I/h is adjusted in the range between 2:1 and 4:1. 2.3 The method is used for stearin production from animal or plant fats. 3.

Abstract: A method of and equipment for controlling the content of fat in milk. Whole milk is separated into skim milk. Some of the cream is returned to the skim milk to create a standardized milk. The standardized milk is employed to derive a parameter that dictates how much cream is to be added. The fat contents detected in the standardized milk are exploited to vary the amount of added cream. The density of the skim milk is measured at intervals and the results are stored. The density of the standardized milk is measured and more or less cream is added until a prescribed difference between the skim milk and the standardized milk, corresponding to the desired fat content in the standardized milk, is obtained. The density of the skim milk and that of the standardized milk are measured in the same sensor. The result of each measurement of the density of the skim milk is compared with the stored result.
