The new recirculating spreader-feeder from Flexicon Corporation enables even distribution of powder and bulk coatings onto food products as they pass between the unit's longitudinal discharge hopper and its lower collection hopper.
The recirculating spreader-feeder is a fully mobile unit and is positioned so that a wire conveyor belt carrying items to be coated, passes immediately above the unit's lower collection hopper, as a uniform curtain of the coating material descends from the upper discharge hopper.
A centreless auger along the bottom of the longitudinal collection hopper feeds material into the intake adapter of a side-mounted flexible screw conveyor. This moves the material at a 75 degree incline into a horizontally-oriented conveyor that is positioned above a longitudinal discharge hopper.
Used with the recirculating spreader-feeder, the horizontal conveyor has multiple discharge ports to apportion material across the length of the discharge hopper, and automatically starts and stops to maintain a preset fill level in the hopper. A small-diameter rotating agitator along the bottom of the hopper promotes uniform discharge through an adjustable screen that spans a gap along the hopper bottom.
The conveyors employed are able to move both free-flowing and non-free-flowing materials, including products that pack, cake, smear or degrade. This is carried out with no separation of blended products such as seed mixes and spice blends, regardless of disparities in bulk density or particle size.
The recirculating spreader-feeder is suitable for food and other hygienic applications and features all-stainless construction including motors and vibrators, and quick-disconnect fittings for thorough, rapid wash down.
