Which oil raw materials are not suitable for the cold pressing method of oil press machine? As we all know, the pressing method of oil press machine is generally divided into two ways: cold pressing and hot pressing. The choice of cold pressing method and hot pressing method is not arbitrary, need to choose according to some characteristics of the oil raw materials. The hot pressing method is generally applicable to more oil raw materials, but the cold pressing method is applicable to fewer raw materials. Below we will have a look at the cold pressing method of the oil press machine is not suitable for which oil raw materials.
Which oil raw materials are not suitable for the cold pressing method of oil press machine? Soybean, high erucic acid rapeseed, cottonseed, peanuts, sesame, for example, soybean oil contains a very strong soy flavor, high erucic acid rapeseed oil in the pungent, cottonseed oil in the flour toxins and spoiled oil aflatoxins, etc., the oil press is only through the simple cold press can not be directly consumed, to be refined by the refining equipment after the refinery to remove its defects. The flavor of sesame oil and peanut oil, before pressing and through the steaming and stir-frying, pressing the hot press process can be obtained.
The cold pressing method of oil press machine will have a great influence on the quality of cold pressed oil due to the different maturity of raw materials and the influence of harmful substances contained in the raw materials, so the raw materials for cold pressed oil should be carefully selected before pressing, and the raw materials have to be crushed before pressing, and sometimes it is necessary to carry out the second and third pressing and so on, in order to improve the oil yield up.
Why do people still use the cold pressing method of oil press when it has so many defects? This is because cold pressed cooking oil does not go through the frying pan for steaming and stir-frying, and the temperature is relatively low, so there is almost no damage to the nutrients of the oil and fat, and the physiologically active substances in the oil and fat can be preserved intact, to ensure that the original flavor, which is a choice for a healthy life. And now the cold press oil press has been updated and upgraded, we Zhengzhou Zhongrui oil press manufacturer produces cold press oil press with three sections of the screw and three presses, basically the feed embryo one time over can have a very good oil yield, can greatly improve its efficiency, is your investment in small, medium and large-scale oil presses are a good choice.
