Raw materials of vegetable oil processing : soybean, sunflower seeds, rapeseed, cotton seeds, corn germ, peanut, rice bran, sesame seeds, flaxseed and so on.
Raw materials of Animal oil processing: pig fat, sheep fat, fish fat, chicken fat and so on.
Oil plants pre-treatment is a series of treatments including cleaning, peeling, crushing, softening, rolling embryo, puffing, damp heat treatment and drying after which the oil is extracted. The purpose is to remove the impurities and make the raw materials into a certain structural property to meet the requirements of different technology.
Vegetable oil production process: pre-treatment, pressing, leaching, crude oil refining, oil filling.
Small production without shelling can save costs while big scale with shelling can raise the protein content of the meal, and therefore improve the quality of oil.
According to the different requirements of customers, we can do projects from 10 tons to 2000 tons.
Generally there are two ways in making Edible vegetable oil: press and leaching. Press can be divided into hot pressing and cold pressing.
Characteristics of cold pressing are following: need relatively low temperature, low oil yield, pale oil, less impurities, retain more nutrients, suitable for high-grade health oil and some s mall variety of oil which is not suitable for heating.
Raw materials suitable for hot pressing: sesame seeds, peanuts, sunflower, rapeseed, soybean, corn germ, wheat germ and so on.
Expanded leaching process
Pressing squeezes as much as possible oil out from the oil materials with cake residue for about 7%, while the pre-pressing only squeeze 80% of the oil with cake residue of 8% to 16% which means the cakes need to be leached then.
