The requirements of the oil press for raw materials

First we need to know what kind of raw materials can be pressed by the oil press.

For the screw oil press or hydraulic press, as long as the granular, oil-bearing plant seeds or pulp, or even chemical raw materials, such as cashew nuts shells can be processed.

However, in order not to affect the oil yield and output, and the useful life of machine parts, the crop into the oil expeller should meet some relevant conditions.

1. Control the moisture and temperature of the material , the temperature of the frying chamber 。

2. Raw materials with shell, such as peanuts, tea seeds, sunflower seeds, etc. should be deshelled.

3.Raw materials with hard shell , such as palm kernel, must be deshelled, otherwise the oil press can not work properly.

4. With soft shell materials, such as rapeseed, sesame seeds do not need to be dehulled.

Of course, if the material into the crusher before processing, can improve the oil yield and output. If the material is uncommon, how to determine whether it can be pressed? 

The answer is that granular materials with an oil content of 8% or more ,and without hard shells are fine.
