Thick aroma rapeseed oil cold smelting technological method

The invention discloses a method of treating water and sediments in crude rapeseed oil by utilizing a cold filtering process technology and relates to a method of carrying out freezing crystallization by adding water to the squeezed crude rapeseed oil and removing the water and the sediments by segmented multistage filtering. The method comprises the following steps: (1) selecting rapeseeds, and removing the water and the sediments; (2) carrying out flaking by virtue of a flaking mill; (3) carrying out frying by virtue of a roller seed frying machine; (4) squeezing to obtain thick aroma crude rapeseed oil; (5) removing large impurities by virtue of an oil clarification tank; (6) carrying out primary filtration; (7) carrying out freezing crystallization by adding water; (8) filtering in a blade; (9) fine filtration by virtue of pressure; and (10) filling. By adopting the method, any chemical component such as acid, base and the like is not added, the nutritional ingredients of the rapeseed ...
