Pump machine is mainly used with multifunctional molding machine and various hot pot material molding machine, mainly play a filling, grouting, coloring and other auxiliary functions. Reasonable gear pump cavity design makes the flow pressure, grouting stable, double insulation cooling device, so that the hopper slurry long time production to maintain a fresh low temperature, the use of dual speed control device, adjustable flow, operation user-friendly, is the production of frozen seasoned food necessary equipment. When changing to different molds, it can make various patterns and shapes of products, so that the variety of products can be blossomed.
