Sanitary high lift drum dumper loads at floor level

December 2, 2009
The sanitary high lift dumper allows drums to be loaded at floor level, sealed against a discharge cone, elevated and tipped, mating the cone to a gasketted receiving ring on downstream process equipment. The dumper accommodates drums from 30 to 55 gallons and can discharge bulk material into process vessels and equipment inlets 5 to 10 feet above the plant floor. The drum platform is raised by a single hydraulic cylinder, creating a dust-tight seal between the rim of a drum and the underside of the discharge cone. A second hydraulic cylinder raises the platform-hood assembly vertically before tipping it to a dump angle of 90 degrees, causing the vertically-oriented cone to mate with a gasketted receiving ring. The ring can be fitted to the lid of an optional hopper with integral flexible screw conveyor or pneumatic pick-up adapter, or to existing process equipment. A pneumatically-actuated slide gate valve prevents material flow until the discharge cone has been properly seated in the gasketted receiving ring. The all-stainless unit can be finished to sanitary or industrial standards.
