Abstract
A system for treating oilseeds prior to solvent extraction in which the oilseeds are treated in a microwave dryer to raise their temperature to 140.degree. F., passed hot through two-high rolls to crack the hulls and beans, the hulls are removed in an air sorter while at 140.degree. F., and while still heated, the beans are sent to a flaking roll. The stream from the process to the solvent extractor has less than 5% fines.
Claims2
A process for treating hulled oilseeds comprising the steps of
- (a) heating hulled seeds with microwave energy to a temperature of about 135.degree. to about 160.degree. F. and removing about 0.5-1% moisture,
- (b) moving the heated seeds to a cracking station and immediately cracking the heated oilseeds on a two-high cracking rolls at a temperature of about 135.degree. to 160.degree. F. to form a mix of hulls, fines and meats with no more than about 5% fines on a dry solids basis with respect to the meats,
- (c) moving the mix directly from the cracking station to a separating station and immediately separating and removing the hulls and fines from the meats at a temperature of about 135.degree. to 160.degree. F. by an air stream separator without passing through a primary vibrating screen, the air stream at the separating station being heated by air heated by magnetron cooling fluid from the microwave heating of step (a), and
- (d) moving the meats at said temperature directly to a flaking station without passing through a conditioner and flaking the meats at a temperature of about 135.degree. to 160.degree. F., and returning the fines from step (c) to the flakes means to recover a product having no more than about 5% fines.
