AI Technical Summary
When the traditional spiral oil press is working, the vegetable oil is continuously pressed in the press chamber for a long time, which causes the press chamber to heat up too high, which is not conducive to the quality of the pressed oil. The existing spray cooling methods cannot effectively cool down, the cooling oil cannot enter the press chamber, and can only cool down outside, and the cooling effect is not good.
An oil press with a thermally conductive type press cage cooling structure of a press cage is designed. The press cage is equipped with a parallel annular bracket and a press strip arranged in the circumferential direction. A cooling channel is provided in the press strip. The cooling oil is introduced into the press strip through the cooling inlet and outlet to achieve effective cooling of the press strip and the press chamber.
By opening a cooling channel in the press strip, the cooling oil can effectively cool the press strip, improve the cooling effect on the press chamber and improve the quality of the oil.

It has the advantages of large continuous processing capacity, short dynamic pressing time, high oil yield and low labor intensity. However, when this traditional screw oil press is working, the temperature of the pressing chamber is too high because the vegetable oil is continuously pressed in the pressing chamber of the oil press for a long time, which is not conducive to the quality of the pressed oil. If the oil is sprayed and cooled directly on the pressing chamber, it can play a certain cooling effect on the pressing chamber, but due to the high pressure in the pressing chamber, the cooling oil cannot enter the pressing chamber and can only be cooled outside the pressing chamber, that is, the cooling oil can only flow through the outer surface of the pressing bar to cool it down, and the cooling effect on the pressing bar still needs to be improved.
