Verfahren zum Behandeln von Sojabohnen.

摘要

A process for converting raw soybean materials into soybean oil and soybean meal without flaking the soybeans during the process is disclosed. The soybeans are cracked into a plurality of kernal portions and hull portions. The cracked kernal portions are then pulverized in a hammerhill (3) and are conveyed to a screw-type conveyor (10) wherein steam is injected through the screw conveyor housing. Breaker pins extend radially inwardly from the screw housing and are located between rotating screw flights so as to provide a working, sheering action on the steam-treated particles as they are conveyed by the screw conveyor. A die plate with apertures therein is disposed at the downstream portion of the screw conveyor and in fluid-tight relationship therewith to form back pressure. The steam-treated particles exit the die plate through the apertures in the form of pellets.
