Hot Oil Press Machine
Most of the vegetable oils we eat in daily life are hot pressed oil, that is, the oil is cleaned and broken before being processed by high-temperature heating which causes a series of changes inside the oil: damaging oil cells, promoting protein denaturation, reducing oil viscosity, etc. Oil yield can be increased in this way. But the color of the hot pressed oil is darker and the price of acid is higher. At the same time, high-temperature oil extraction results in great loss of bioactive substances (vitamin E, sterol, Carotenoids, etc.) in the crushing process, which is a great waste of resources.
Take cottonseed, peanut, and sesame as examples, gossypol toxins in cottonseed oil and aflatoxins in deteriorated oil must be refined before they can be removed. The fragrance of sesame oil and peanut oil can only be obtained by hot pressing. So all of these materials need to be extracted with a hot oil press machine.
The advantage of hot oil press machine over cold oil press
- ℃; And cold pressed oil press need 30 ~ 40 minutes to reach about 90 ℃ by its material friction.
