What's the difference of oil press machine between a cold press and a hot press?

Oil press machine as crimping machinery oil crops, then the type of press can be divided into: hot press and cold press two, then what is the difference between between them and the advantages and disadvantages?Cold pressed oil mill: as the name implies, is in the oil without heating, after screening clean directly into the oil press press, way of squeezing squeeze very hard clean, once out of cake and oil content, also some need this type of a press cake, less oil content, but is not entirely without oil.So the advantage of the cold pressed is that the color is lighter, the oil is not bubbling, and the silt is not present, the color is better.The disadvantage is that the oil is not very fragrant, and it takes more than two times to squeeze clean.Oil mill of hot pressing, hot pressing is contrary to cold pressed oils after heated to squeeze, the squeeze mode is one-time can squeeze a clean, is almost no oil content of cake, the cake is completely deoiling cake, can use when making materials without oil cake.Hot press is the advantages of squeeze oil is very sweet, after hot with the oil is cold pressed more than oil, but because it is hot press all can appear sometimes silting the phenomenon of pot, this needs to be noted at the time of pressing, squeezing in don't feeding too anxious, according to squeeze out the oil under the right amount of material.
It takes more than two or three times to get the material cleaned up from the squeeze, but the hot press just needs to be done.Of course, the cold press is not as stressed as the heat press, so you squeeze the head less, and the cold press is usually two pressing heads, and the heat squeeze is usually at least two or more than four.Has grown two millimeters to squeeze pressure on both difference is very big, hot pressing pressure is cold pressed 4-6 times more, so the oil materials only once extrusion so thoroughly and the above situation is inseparable.
Followed by rotational speed is not the same, say first hot oil mill speed in 36 turn around, and cold pressing is in 75 turn above, such a high speed, of course, the pressure is much smaller.So hot and cold press difference is not just squeeze head number and pressure difference, in terms of parameter and design are difference is very big, need to know these things for customers we buy small oil mill is a very important reference standard, which is cold pressed and hot pressed key factors and the difference.
