Because of different yield, nutritional value and value of various oils, so there is a big difference in price. There are many varieties of edible oil, a common soybean oil, corn oil, sesame oil, peanut oil, rapeseed oil and the like. Hengtong machinery technician to tell you why sesame peanut oil crops choose hot virgin cold-pressed process rather than reason
1), sesame oil and fragrant peanut flavor, it must go through to get hot pressing process. After the high temperature treatment by oil squeeze color darker hair oil, acid value increased. At the same temperature so that the oil in the oil extraction of bioactive substances (vitamin E, sterols, classes vegetarian carrots, etc.) in the press during the great loss, resulting in a waste of resources.
2) In recent years, with the improvement of people's living standards, more and more people of all ages in terms of cold edible oil extraction. Cold press is in front of the press without heating fuel or low state, squeezing into the small press. Squeeze lower oil temperature, acid value is low, generally do not need refining, after precipitation and filtration to obtain refined petroleum products. Cold oil extraction has natural properties, to avoid the adverse effects of conventional oil extraction process produces a high temperature. Cold-pressed oil refined oil retained in natural flavor and color, complete preservation of the oil physiologically active substances (vitamin E has anti-aging functions, sterols have healthy skin function and enhance the body's metabolic functions), cold oil extraction authentic, is to choose a healthy life.
3) FIRST hydraulic press equipment of a machine, regardless of differences in climatic conditions across the country, the real effect of the boot to the oil, the machine uses a forced feeding device, feeding the average rate, press speed, can be widely press peanuts, soybeans, rapeseed, sesame, sunflower, linseed, mountain tea seed, cotton seed, pepper seed, walnut, tung...
