Vacuum filling mixer is the main equipment used for mixing materials. Under vacuum conditions, the material is stirred evenly, fully expanded, without bubbles, and has good elasticity, which is an excellent equipment for improving product quality. The whole machine is made of stainless steel, which is sturdy, durable, and easy to clean. Adopting a parallel double axis spiral structure, equipped with inclined plate blades and spiral driven mixing rings, the mixing is uniform. The vacuum degree can be arbitrarily set to enable the material to be stirred in a good vacuum state.
