Patent ID: 8105639

Claim:
A process for precooking grains or soybeans in a reactor, comprising the steps of: a) charging a monitored amount of grains or soybeans from a feeder into the reactor; b) applying a first negative pressure to reduce the internal pressure within the reactor so that the internal pressure ranges from a relative pressure of 4 kg/cm 2 to an absolute pressure of 6 mmHg; c) heating the grains or soybeans contained in the reactor up to a temperature range from 100° C. to 125° C. and maintaining the grains or soybeans at said temperature for a determined period of time; d) applying a second negative pressure to the reactor to obtain a pressure differential of from 1.4 to 2.5 kg/cm 2 while dragging off water, toxins, mycotoxins and pesticides from the grains or soybeans; and e) vacuum cooling the grains or soybeans in the reactor to obtain a cooled humid or dry grain or soybean product.
