Using the working principle of the jack, the hydraulic pressure tonnage can be selected from 30 tons, 50 tons, 60 tons, 80 tons, and 100 tons, which can be matched with different specifications and models of presses. The press machine is mainly composed of a frame, hydraulic station, oil well, pressure plate, motor, oil tank, and barrel combination. The base, cover, and material bucket are wrapped in 304 stainless steel and stainless steel plates. Operating method of the press: The material is manually loaded into the barrel of the press. The bottom of the barrel is equipped with pulleys, which push the bottom of the press plate through the track for pressing. The material of the barrel is food grade SUS304 stainless steel. Turn on the power and start the equipment. According to the dehydration status of the product, perform a step press (in layman's terms, it can allow the water squeezed out of the barrel to flow out of time, achieving the ideal dehydration state), so that the liquid or water contained in the material is squeezed out, and the squeezed liquid flows out from the barrel wall hole. The hydraulic disc is wrapped in full 304 stainless steel to meet the hygiene and safety requirements of the contact area with the material. After the product pressing is completed, reset the hydraulic disc. After the squeezing is completed, pour out the material and take turns for the next squeezing.
