Shick Esteve’s bag dump facilitates the addition of dry ingredients into a pneumatic convey line. The design includes a hopper with a gas spring assisted door that makes hand adding easier. An air-actuated cartridge filter sealing mechanism that is not exposed to the material contact area makes cartridge replacement fast, simple and tool free. The bag dump comes with an integral dust collection system with a fan that can be activated upon opening the door. The filter cleaning cycle directs captured material into the hopper for introduction into the transfer system. A removable air curtain directs air flow so dust is pulled away from the operator.
