Shanyouteng refiner is very good. Its advantage lies in that it is not only a fully automatic refiner, but also an automatic refiner with one key, and there is no need for special supervision during the refining process. High grinding speed, automatic separation of pulp and residue and efficient extraction of protein can improve the yield of bean products. Secondly, according to the different needs of different customers' production and output, the configuration of automatic refiner is also quite different, and the grinding speed and automation degree are also different. The refiner can automatically feed beans according to customers' production needs, without manual feeding. Among them, two refiners and three refiners can automatically control the flow of water, so as to adjust the concentration of soybean milk and better ensure the yield of soybean products.
