InLine Dryer/Roaster

The Inline Dryer/Roaster is designed to enhance the drying and roasting process for various oilseeds and other products.

Product is fed onto the conveyor at the infeed section and distributed across the band by means of a Ramshorn Spreader, Scarf-edge Vibratory Feeder, Oscillating Belt Spreader or a Rake Spreader. The spreader evenly spreads the product out to the required uniform depth across the entire width of the conveyor.

The conveyor transports the product through the heating zone(s), where a re-circulation process air impeller draws air up through the product layer in the first length of the heating zone then downwards through the product layer in the second length of the heating zone.
The product can then travel through a cooling section where cool air is drawn through filters mounted in the roof of the cooler, down through the product, then back up through the duct by the cooling fan, before being exhausted.

The conveyor belt speed is controlled by a variable speed drive to allow the dryer retention time to be altered as required. The set point temperature is input via a touch screen control panel. The operating temperature is measured by sensors mounted in the roof and controlled by a modulating valve on the burner.
