There are various methods for the processing of soybeans. The most effective soya processing method consists of a combination of heat treatment and crushing. This method removes the anti-nutritional factor and makes the oil more accessible. See below for an overview of the steps in soybean processing:
Jaw crushing is a mechanical size reduction process for large chunks of friable material such as rocks or ceramics. The crushing is achieved by using compressive forces between two plates (jaws) to break the substrates. One plate is typically fixed in a "V" alignment while the other plate reciprocates resulting in the crushing action.
