There are three main differences between the sterilization of palm oil pressing pretreatment and the steaming and frying of ordinary edible oil:
1. Different processing raw materials:
Palm oil pressing and sterilization treatment, the raw material is palm fruit or palm fruit bunch
The raw materials for steaming and frying with common cooking oil are soybeans, peanuts, sunflower seeds, etc.
2. Different processing tools:
Palm fruit sterilization uses a sterilization tank;
Ordinary edible oil steaming and frying uses a steaming wok.
3. Different functions:
Palm sterilization: Use steam to cook palm fruit at high temperature to destroy the lipase in the pulp to prevent the free fatty acid content in the oil from increasing. In addition, high-temperature sterilization can make the fruit soft and easy for mechanical threshing.
Steaming and frying: the processing equipment for making mature embryos by moistening, steaming and frying the raw embryos after flaking, so as to meet the technological requirements of subsequent pressing or leaching, and can also be used as a softening pot. The softening of oil can improve the quality of flaking, In turn, it can improve the oil yield and improve the quality of crude oil. It is an essential equipment for vegetable oil pretreatment in vegetable oil factories.
