The black oil output of the oil press is not due to the problem of the oil press itself. There are many reasons for the black oil output of the oil press. Today, I will explain to you how to solve the black oil output of the oil press and the reasons for the black oil output of the oil press.

The main reasons for the black oil output 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 crop stems and leaves, soil, stones, silt, iron filings and other impurities. These impurities will not only affect the oil yield, but also affect

The color of oil sounds.

2. Regarding the blackening of the oil output from the oil press, this step of frying is also very important. If the heat is too high, the temperature is too high, and the speed is too fast during frying, it will affect the oil color of the oil.

3. If the filtration is not done properly, the oil color will turn black.

Effective ways to solve the blackening of the oil output of the oil press:

1. In the cleaning step, the oil needs to be finely cleaned. Generally, the commonly used equipment to help the oil cleaning includes a cleaning screen, a stone removal machine, a magnetic separator, etc. The filtered oil will increase in both the oil yield and the oil color when it enters the oil press.

2. In the process of heating pretreatment or frying, try to use a small fire, lower the temperature, and appropriately extend the frying time.

3. The crude oil needs to be filtered immediately after the oil is pressed by the oil press, and the oil residue in the oil must be filtered out, otherwise it will be difficult to clear the oil color no matter how it is processed. It is recommended to use Shuangxiang vacuum oil filter.

4. The squeezing equipment uses a fully automatic oil press, that is, a round row oil press, because the round row machine can provide the maximum pressure of the frying chamber in the largest unit section to ensure that the oil is squeezed out after the crop is fed, and the oil is squeezed into a cake. . No need to squeeze at high temperature twice. It is important to know that high temperature has a great influence on oil color.
