BTMA-How To Solve The Black Oil From The Oil Press？
First of all, you must understand that the black oil produced by the oil press is not due to the problem of the oil press machine itself.
There are many reasons for the high output of black oil from oil press. Today I will explain to you how to solve the problem of black oil coming out of a oil press, and the reasons for the black oil coming out of a oil press.
The main reasons for the black out of the oil press
1. The raw materials must be cleaned before the oil is pressed by the oil press. The uncleaned oil is more or less mixed with impurities such as crop stems and leaves, soil, stones, silt, and iron filings. These impurities not only affect the oil yield, but also affect the color of the oil.
2. For the blackening of the oil produced by the oil press, the frying step is also very important. When frying, if the heat is too high, the temperature is too high, or the speed is too fast, it will affect the oil color.
3. If it is not filtered properly, the oil will turn black.
Effective methods to solve the blackening of the oil output of the hydraulic machine
1. In the cleaning step, the oil needs to be finely cleaned. Generally speaking, the commonly used equipment to help oil pollution is cleaning screens, stone removers, magnetic separators, etc. After the filtered oil enters the oil press, the oil yield and oil color are improved.
2. In the heating pretreatment or cooking process, try to use a low fire, lower the temperature, and appropriately extend the frying time.
3 、After the oil is pressed by the oil press, the crude oil must be filtered immediately, and the oil residue in the oil must be filtered out, otherwise it will be difficult to remove the oil color in any treatment. It is recommended to use an oil filter.
4、The extrusion equipment uses a fully automatic oil press, that is, a circular row oil press, because the circular row machine can provide the largest unit part of the maximum pressure, ensuring that the oil is squeezed out according to the crop and then sent to the cake. . No need to squeeze twice at high temperature. You know, high temperature has a great influence on oil color.
