Title: Method and device for obtaining stearin from animal or vegetable fats

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. FIG. 2.
