Method of using traditional oil pressing set to produce linseed oil in low temperature

Abstract

The invention discloses a method for producing low temperature pressing linseed oil with the conventional oil press, which comprises the following steps: placing the well selected linseed raw material into a flaker for flaking; placing the linseed embryo into a steam cooker and cooking in a temperature of 40-50 DEG C; and then stir-frying the linseed embryo in a temperature of 58-60 DEG C; putting the well fried embryo material into a common oil press to press for one minute in normal temperature and acquiring low temperature crude oil and oil cake; then repetitively stir-frying and the first pressing to the oil cake to acquire low temperature crude oil and oil cake. The invention is characterized in that adopting the common oil press to press in low temperature can damage less nutrition and produce oil product with high quality and can not destroy other components of linseed.

Description

technical field [0001] The invention belongs to the technical field of edible oil processing and production methods, and in particular relates to a method for producing low-temperature pressed linseed oil by using traditional oil pressing equipment. Background technique [0002] Flaxseed is one of the top ten oil crops in the world. Its main components are 30-40% fat, 10-30% protein, more than 12% linseed gum, lignans, vitamins and other natural nutrients that are beneficial to the human body. For a long time, in order to obtain linseed oil, people have used high-temperature steaming, frying and pressing to make oil or solvent leaching and high-temperature refining to make oil, so that the beneficial substances other than oil will change properties due to high temperature, and can only become fertilizer or feed. The use of a large number of natural nutrients Reduced value. The production of flaxseed oil by low-temperature pressing is of great significance for the comprehens...

Problems solved by technology

[0004] The process steps of low-temperature pressing are similar to the traditional high-temperature process, but as far as the current domestic and foreign situations are concerned, it is difficult for traditional high-temperature oil pressing equipment to produce low-temperature pressed vegetable oil, such as the LYZX low-temperature screw press in my country and the rapeseed cold press in Germany. , are all special-purpose equipment, which are difficult to apply to the production of low-temperature linseed oil. At the same time, the production efficiency of these equipment is only 25 tons per day, which cannot meet the needs of large-scale oil production enterprises (more than 1,000 tons of oil per day).
