Driers

Contact Drier

The Rendertech Contact Drier (CD) is an indirect steam heated, continuous drier for drying a variety of granular and fluid materials including sticky and difficult to handle materials including concentrate from evaporators. The drier consists of a horizontal shaft carrying a number of steam heated hollow discs that rotate in the product. Fitted to the edge of the discs are agitator paddles to transport the material along the drier.

Materials of construction are selected to suit the application and extensive use of stainless steel is typical to ensure a long life. The CD is simple to operate and maintain. The exhaust from the drier is predominantly water vapour with a small amount of air. Volumes to condense and deodorize are consequently small.

Applications include  bone/meatmeal, fishmeal, feathermeal, bloodmeal, biosolids, brewer’s grain. The drier is also used as a continuous cooker in the Continuous Dry Rendering Process.
