Controlling receiving pit dust adds money to business. By keeping dust with the grain, shrinkage is reduced and grain mass is maintained. The ABC Dustmaster uses a simple, common-sense patented design that keeps the dust with the grain. It offers an efficient and economical solution to controlling up to 96% of receiving pit grain dust emissions. Louvers covering the receiving pit suppress grain dust, reducing shrinkage and eliminating the need to dispose of collected dust.
Rows of heavy steel louvers, installed 15 to 20 centimeters below the pit grate, cover and seal the entire pit. When a wagon or truck is unloaded, pneumatically operated cylinders open only the louvers directly beneath the unloading area; the remaining louvers over the pit remain in the closed position. The louvers blanket the pit during unloading, physically keeping grain dust in the pit.
Dustmaster-fitted pits will not slow down unloading operations. Grain is handled at the same capacity rate as pits without the Dustmaster. While louvers cover the entire pit, automatic sensors open the appropriate number of louvers to handle grain flow during unloading. Pit capacity is not negatively affected.
Open and close functions, which allow grain to flow into the pit, are controlled by a small air compressor, triggered by sensor switches installed on the louvers. The Dustmaster automatically senses how many louvers to open to control dust and allow grain to flow.
The system works with all size pits because it is custom built and installed. When compared with vacuum operated dust control systems, the Dustmaster is much quieter and is 50% less expensive in capital and installation costs. Operational energy needs and associated costs are a fraction of air-based control systems.
