How To Solve The Black Oil Output Of The Oil Press

     First of all, you must understand that the black oil output from 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 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 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, the frying step is also very important. If the heat is too high, the temperature is too high, or 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 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 improve in terms of oil yield and oil color when entering the oil press.

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

      3. The crude oil must 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  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 in the largest unit section to ensure that the oil is squeezed out by one press after the crop is fed into a cake. . No need to squeeze at high temperature twice. It should be known that high temperature has a great influence on oil color.
