Definition&Advantage of Cold Press by Cold Oil Press Machine

Cold oil press machine is popular in some countries with the raw materials coconut or olive and so on.
What are the benefits of a cold press and a cold press? In recent years, with the continuous improvement of people 's living standards in the cooking oil, people are increasingly popular cold press oil press.... Cold oil press is in the oil before pressing without heating or low temperature of the state, give the press press. Compression of the oil temperature is low, acid prices are lower, generally do not need refining, after precipitation and filtration to be refined oil. Cold oil has a pure natural characteristics, to avoid the traditional high-temperature oil extraction processing adverse effects. Cold pressed oil retains the natural flavor and color of the oil, the complete preservation of the oil in the physiologically active substances (vitamin E has anti-aging function, sterol has a skin effect and enhance the body's metabolic function), cold pressed juice authentic, Is the choice of healthy living. However, most of the oil is not suitable for cold pressing, soybeans, high erucic acid, rapeseed, peanut, sesame, for example, soybean oil contains bean flavor, high erucic acid rapeseed oil in the spicy, cottonseed oil Gossypol toxin and metamorphic oil in aflatoxin, etc., must be refined to remove. And sesame oil and fragrant peanut oil flavor, but also must be hot pressing process can be. The raw materials of cold oil must be selected, otherwise the raw materials of different maturity and raw materials contained in harmful substances (such as moldy oil in the aflatoxin and cottonseed gossypol toxin), will be cold The quality of oil extraction seriously affected. General mining, cold pressing the low smoke, moisture content is not stable, is not conducive to long-term storage. Cold pressing generally need to crush the oil out to go after, and sometimes have two press, three press. Hot pressing is generally used for large-scale machine pre-pressing, which is the first oil extraction, but there are some manufacturers improved models directly after the oil extraction, do not need other equipment, such as Guangzhou Institute of Machinery is used three sections Spirals composed of three, basically a material embryo will be able to have a good oil rate. Cold pressing generally need to crush the oil out to go after, and sometimes have two press, three press. Hot pressing is generally used for large-scale machine pre-pressing, which is the first oil extraction, but there are also some manufacturers improved models used directly after the oil extraction, do not need.
