Shanyouteng refiner is very good. Its advantage lies in that it is not only a fully automatic refiner, but also a one-button automatic refiner, and there is no need for special supervision in the refining process. High grinding speed, automatic separation of slurry and residue, and efficient extraction by protein, which improves the yield of bean products. Secondly, according to the different requirements of different customers' production 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 the production needs of customers, 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 output of soybean products.
