Advanced design:The vacuum feeding machine adopts advanced design, consisting of a vacuum pump (oil-free, waterless), a multi option filter (including polyester film, PE, 316L stainless steel or titanium metal filters), a compressed air blowback device, a pneumatic discharge door, a material level automatic control device, a stainless steel suction nozzle and a conveying hose, etc. The device generates negative pressure through a vacuum pump, creating a vacuum airflow that sucks in materials and transfers them to the silo through a suction tube. The filter effectively separates materials from air. When the silo is full, the controller automatically stops the vacuum generator and opens the silo door to smoothly unload the materials to downstream equipment. This system provides an efficient, hygienic, and automated material handling solution.
