Cold pressing and hot pressing are two methods in oil extracting oil. How do they work in the process of oil extracting?

Cold pressing do not need to heat oil bearing materials, so it may have relatively low oil yield, light-colored crude oil, less impurity. But it will retain more nutrition of oil. Under this oil producing method, oil will not have bubbles when cooking and will not lead to lit in people. So it is healthier.

Hot pressing need to heat oil bearing seeds (steaming and frying) and it provides higher 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.

Under cold pressing, oilseeds will be pressed directly without frying. Due to this, the oil will be very clear. While the oil temperature is also very high in the pressing process, the same as hot pressing.

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