The rapeseed oil press is a purely physical squeezer, and the rapeseed is squeezed by the internal pressure of the press chamber to let the oil in the rapeseed come out. For the equipment, the core component is snail pressing, which is a normal wear part.
Some customers will experience low oil yield or slag after using for a period of time. Many customers will consider what the problem is. In fact, this It may be because the snails are worn out and need to be replaced. The main function of the snails is to promote the feeding of rapeseed for squeezing. The rapeseed oil press is a three-stage press, that is, three pressure heads.
The material of the snails is very critical. There are many types of rapeseed oil press on the market, and the quality of the core components of the snail press is also uneven.
The snails are made of No. 45 steel. No. 45 steel is a relatively cheap material. This usually needs to be replaced for 100,000 kg. This type is usually used for older oil presses
There are also 20-column, which is better than 45-grade steel. A slightly better material, this is generally squeezed from 100,000 to 200,000 kg and needs to be replaced.
The third type is C12 die steel material. The price of Cr12 die steel material is much more expensive, and this is heat-treated, this can squeeze 600-800,000 kg.
Some customers do not need to replace it after a year or two. The pros and cons of the snails directly affect the service life of the machine. A good material can be abrasion-resistant, high-temperature resistant, and hard. This is because the prices of rapeseed oil presses on the market are different, some are a little higher, and some are lower.
What you pay for what you pay for, customers can judge the quality of the equipment from the details, and buy a good-quality machine that has a long service life and is not prone to failure.
