Cold Pressing Vs. Hot Pressing

by Anne Green Sales Manager

Bacially, there are two methods in oil extracting oil, cold pressing and hot pressing. How do they work in the process of oil extracting?

The cold pressing do not need to heat oil bearing materials, low oil yield, light-colored crude oil, less impurity, retain the more nutrition of oil. Cold pressing is a kind of method which suit for that some not proper heating small breed oil seeds and health care oil.

The hot pressing need to heat oil bearing seeds (steaming and frying), high yield, which is the common method.

A feature of hot pressing is high oil yield, but the oil is less bright than the oil through cold pressing. The oil raw material through cold press which was pressed directly not use frying, the oil temperature is also very high when pressing, the same as hot pressing. Because the oil material was pressed directly, the oil was very clear.

Whirlston oil pressing machines are suitable for both methods during oil extracting. Welcome your coming.
