Example Embodiment
[0029] The present invention will be further described below in conjunction with specific embodiments, so that those skilled in the art can better understand the present invention, but the present invention is not limited thereto. Example 1
[0030] Mix corn germ meal and corn oil soapstock in a ratio of 1:3, and stir evenly. Send the well-stirred mixture of corn oil soapstock and corn germ into the granulator. The shaped material has a diameter of 3 mm and a moisture content of 40%.
[0031] The molded material is dried by a roaster, the drying temperature is 120℃, and the moisture content after drying is 0.3%. The mass ratio of solvent to material is 1:1. The scraper and sealing screw enter the extractor for leaching. The materials are sprayed and immersed in the solvent cycle to form a mixed oil. The spray was sprayed for 6 times, the first 5 times were leached with mixed oil, the gradient oil concentration of the mixed oil was 30%, 25%, 20%, 15%, 10%, and the 6th time was l...
Example Embodiment
[0035] Example 2
[0036] Mix corn germ meal and corn oil soapstock in a ratio of 1:4, and stir evenly. Send the well-stirred mixture of corn oil soapstock and corn germ into the granulator. The shaped material has a diameter of 4 mm and a moisture content of 45%.
[0037] The molded material is dried by a roaster, the drying temperature is 130℃, and the moisture content after drying is 3%. The mass ratio of solvent to material is 0.5:1. The scraper and sealing screw enter the extractor for leaching. The materials are sprayed and immersed in the solvent cycle to form a mixed oil. The spray was sprayed for 6 times, the first 5 times were leached with mixed oil, the gradient oil concentration of the mixed oil was 30%, 25%, 20%, 15%, 10%, and the 6th time was leached with fresh acetone. Spray for 5 minutes each time. The drained materials are then passed through a scraper, the feed auger is sealed, and then enters the steaming machine for desolvation, and then is sent to the meal...
Example Embodiment
[0041] Example 3
[0042] Mix corn germ meal and corn oil soapstock in a ratio of 1:6, and stir evenly. Send the well-stirred mixture of corn oil soapstock and corn germ into the granulator. The shaped material has a diameter of 6 mm and a moisture content of 50%.
[0043] The molded material is dried by a roasting meal machine. The drying temperature is 150℃, the moisture content after drying is 6%, and the mass ratio of the solvent to the material is 1.2:1. It enters the extractor through a scraper and a sealed auger for leaching. The materials are sprayed and immersed in the solvent cycle to form a mixed oil. The spray was sprayed for 6 times, the first 5 times were leached with mixed oil, the gradient oil concentration of the mixed oil was 30%, 25%, 20%, 15%, 10%, and the 6th time was leached with fresh acetone. Spray for 5 minutes each time. The drained materials are then passed through a scraper, the feed auger is sealed, and then enters the steaming machine for desolvatio...
