Can wet material be pressed by hydraulic oil press?
Soybean water is not handled well, our hydraulic oil press will have a series of problems, and this is an important factor directly affecting the oil yield, often there will be no feed or feed less phenomenon.
Steaming and frying is one of the important processes in the process of oil production. Steamed frying can make great changes in the internal structure of oil with the help of water and temperature, such as further destruction of cells, solidification denaturation of proteins, segregation and combination of phospholipid and gossypol, etc. These changes are not only conducive to the easy separation of oil from oil, but also conducive to the improvement of the quality of crude oil. The pressing moisture and temperature of main oil embryos were as follows: the pressing moisture of soybean was 1.5-2.8%, and the pressing temperature was about 128℃. The pressed water of peanut kernel is 1.0-2.0% and the pressed temperature is about 130℃. The pressed water of cottonseed is 1.5-2.5% and the pressed temperature is 125-128℃.
The pressing water of rapeseed is 1.0-1.5%, and the pressing temperature is about 130℃. The pressing water of sesame is 1.2-2.0%, and the pressing temperature is 125-130℃. The pressing water of rice bran is 2.5-3.6%, and the pressing temperature is 120-125℃. Oil press raw material moisture is too low will also affect the oil yield, the cake is not tile block and become broken; The motor load is high, the main oil outlet position moves to the cake outlet end, the oil outlet is reduced, the oil color is dark brown.
