Claims
- 1. A system for processing oilseeds including
- (a) a microwave dryer in which oilseeds are heated to about 160.degree. F. and about 0.5 to 1.0% moisture is removed,
- (b) a two-high cracking roll which receives the heated oilseeds directly from the microwave dryer at the temperature of about 135.degree. to about 160.degree. F. and where the heated oilseeds are crushed to remove the hulls without the production of large quantities of fines,
- (c) a primary aspirator and primary cyclone system which receives separating air and which directly receives the crushed, heated oilseeds and where the hulls and fines are separated from the seed meats,
- (d) means for heating the separating air for the aspirator to maintain the temperature of the seed meats at about 135.degree. to about 160.degree. F. during separation,
- (e) a secondary aspirator and secondary cyclone system where the hulls are separated from the fines,
- (f) a flaking roll where the seed meats are flaked,
- (g) means for moving the seed meats directly from the primary aspirator in heated condition at the temperature of about 135.degree. to about 160.degree. F. to the flaking roll, and
- (h) means for combining the fines with the flaked oilseed meats to form a feed for an oil extraction system.
- 2. The system of claim 1 wherein the means for heating the air is the magnetron cooling water from the microwave heater.
- 3. The system of claim 1 including a hull roaster where the hulls and any entrained fines are toasted.
- 4. The system of claim 1 wherein the oil extraction feed has less than about 5% fines.
- 5. A system for processing oilseeds including
- (a) microwave dryer means for heating the oilseeds to about 135.degree. to about 160.degree. F.,
- (b) a cracking, hull removal and flaking arrangement in which the heated beans are passed, while in heated condition, directly from the dryer to two-high cracking rolls, from the rolls directly through air stream sorting means to separate the hulls and fines from seed meats and the seed meats are directly passed, while still heated, to flaking rolls, and
- (c) secondary means for separating the fines from the hulls and passing the fines directly into the feed to an oil extraction system.
- 6. The system of claim 5 wherein the magnetron cooling water from the microwave dryer is used to heat air for the air sorting means to maintain the temperature of the seed meats.
- 7. The system of claim 5 wherein the feed to the oil extraction system has less than about 5% fines.
- 8. A system for processing oilseeds including
- (a) a microwave dryer in which oilseeds are heated to about 135.degree. to about 160.degree. F.,
- (b) two-high cracking rolls for cracking the oilseeds from the dryer at said temperature of about 135.degree. to about 160.degree. F. whereby the oilseeds are crushed to remove the hulls without the production of large quantities of fines,
- (c) means for directly transferring the heated seeds from the microwave dryer to the two-high cracking rolls,
- (d) primary means for air separating the hulls and fines from the seed meats,
- (e) means for directly transferring the crushed oilseeds from the cracking rolls to the primary air separating means,
- (f) means for heating the air to the air separation means to maintain the temperature of the seed meats during separation,
- (g) secondary air separating means where the hulls are separated from the fines,
- (h) a flaking roll where the seed meats are flaked,
- (i) means for moving the heated seed meats from the primary air separator in heated condition to the flaking roll, and
- (j) means for combining the fines with the oilseed meats to form a feed for an oil extraction system.
- 9. The system of claim 8 wherein the means for heating the air for the air separator means is the magnetron cooling water from the microwave heater.
- 10. The system of claim 8 including a hull roaster where the hulls and any entrained fines are toasted
- 11. The system of claim 8 wherein the oil extraction feed has less than about 5% fines.
