Hygienic bag dump station

A Hygienic Bag Dump Station for pneumatic conveying systems collects dust created during manual dumping of bulk materials from bags, boxes, drums and other containers, and allows rapid, tool-free washdown.

Optional rocker arms support the hood assembly above the hopper rim, eliminating the need for operators to lift and remove the hood during cleaning and inspection.

Similarly, a stainless rotary airlock valve at the hopper discharge is equipped with integral support rails that allow the rotor assembly to separate from the valve body for cleaning of all material contact surfaces, and to close securely in seconds, also without tools.

A high-velocity vacuum fan draws airborne dust from the operator’s atmosphere onto two cartridge filters. Automatic reverse-pulse filter cleaning allows continuous, efficient operation; timer-activated solenoid valves release short blasts of compressed plant air inside cartridge filters causing dust build-up on the outer filter surfaces to fall into the hopper.

Filters are accessed easily by removing the interior baffle and replaced rapidly using quick-disconnect fittings.

The all-stainless unit is also offered with an integral flexible screw conveyor, or with universal hopper discharge flange for connection to downstream process equipment, and is available mounted on frames with castors for in-plant mobility.
