Batch Dryer

Batch Type Dryers uses a perforated belt to transfer feed materials through the dryer. Heated air is either passed under and through, or over and through the belt and product bed before being reheated and re-circulated. Units are normally multi zoned and may have differing airflow's in successive zones. Additionally each zone may use a different temperature profile and control. Saturated or close to saturated air is exhausted from the dryer via a central exhaust duct.
Batch Type Dryers may be multi pass units, in which the feed is transferred from one belt to another belt below it by gravity. These dryers are usually two or three pass machines. Additionally certain conveyor dryers, such as those used in vegetable dehydration have multiple belts in line, and the feed is transferred from one belt to another.
