How does pretreatment help in the processing of edible oil?

In the edible oil processing industry, pretreatment mainly includes two steps: cleaning and embryo making, but there are many specific operation processes, covering the cleaning, shelling, crushing, flaking, roasting, and puffing of oil. The pretreatment machines involved mainly include shelling machine, cleaning machine, crushing machine, flaking machine, roasting machine, etc. The pretreatment help in the processing of edible oil, which can improve the oil yield of oil seeds, and maximize the benefit of the factory. That is to say it is indispensable for large and medium-sized cooking oil manufacturers.

So how does this series of oil pretreatment help in the processing of edible oil?

1. Get embryos with good structure and high oil yield

The primary purpose of pretreatment is to put the oil seeds in a state more suitable for pressing and increasing the oil yield. Pretreatment can clean up mechanical impurities in raw materials, improve the shape of oil, increase oil contact area, destroy the internal cell structure, and remove the non-oil part in oil, creating conditions for processing into embryos that can shorten the oil path, and have high oil yield.

2. Get good quality oil and cake

After pretreatment, the oil has less impurities and the final oil extraction rate is high. There are no impurities in the oil, it is easier to filter, and the oil quality is good. The cake size, structure, and state are suitable, not agglomerated or scattered, and can be used for the feed, protein and other by-products.

3. Reduce machine loss and extend machine life

The pretreatment help in the processing of edible oil, which can prevent mechanical impurities such as soil, stones, iron and other impurities from entering the press machine, causing blockage and wear to the machine. In addition, crushing, softening and rolling of some oils with larger particles such as soybeans and peanuts can reduce the pressure of press machine, thus extending the service life of the machine.

Pretreatment help in the processing of edible oil and is an indispensable part of edible oil production. Through the steps of cleaning, crushing, shelling and flaking, not only can the oil yield be greatly improved, but it also helps to ensure the quality and nutritional value of edible oil, obtain high-quality by-products such as cakes and meal, and increase profits.
