A soybean trader surnamed Wang in Northeast China used this kind of oil press before. He said that this kind of domestic oil press can be divided into two types: one is hydraulic oil press, the other is screw oil press; Family oil press is generally screw oil press, not only the cost is high, but also the cost of screw.
Some netizens said that the household oil press actually imitates the model of soybean milk machine to operate and sell, but the household oil press is not as simple as soybean milk machine.
The oil press is small, the pressure is small, the oil yield is low, and the pressed oil is very turbid, so it must be precipitated for many days to eat.
It is difficult to form a climate
Many people in the grain and oil industry believe that the household oil press industry may be just a flash in the pan industry.
According to the above-mentioned manager Xu, from the perspective of the development trend of edible oil processing industry, we should seek benefits from large-scale development. Small scale, workshop type processing is not only unprofessional, but also unsafe. Obviously, it goes against the trend and will not achieve great development.
"This kind of machine, the oil rate is too low, is a waste of raw materials." Some people in the industry said that it is difficult for household oil press to form an industry.
The above manager Wang said that the people around him who used to do business with such oil presses have already discarded these oil presses, so these machines can not bring profits, only bring losses.
In the view of many professionals in the grain and oil processing industry, the short-term revival of family oil press is similar to the popular practice of "purchasing raw materials by oneself and pressing oil by oneself in rural workshops" in big cities in recent years.
"No matter from the control of raw materials or the control of the pressing process, these workshops or families are not safe and healthy, let alone green. It's just a lack of consumer expertise. " Manager Xu said.
Experts say that the oil produced by household presses, without deodorization, decolorization and other processes, can only be equivalent to crude oil, which is even more harmful.
