The tray dryers are heated by means of electrical, steam or oil/ gas fired burners. Promas TM dryers are specially designed to have better efficiency than any other dryers available from other tray dryer manufacturers.

Construction

The dryer cabinet is designed in such a way that the airflow inside the dryer has minimum resistance. Internal surfaces of the dryer are made with well-rounded corners with maximum angle so as to offer least resistance to airflow, resulting in less pressure drop across the corners. The outer body is also fabricated with rounded edges without steps from outside to have smooth finish. The inside fan & radiator / heaters are covered with SS / GI mesh to have safety in operation. The drying oven model having MS body from outside & SS body inside is provided with 150 mm SS collar around the door.

Sealing

The shafts of circulation fan, the inlets & outlets of the radiator coil are sealed by food grade sealing pads which stops the leakage of hot air from the drying cabinet.

Leakages increase drying time of the product inside the trays of the dryer & in some cases causel the air contamination of air inside the dryer. Thus sealing helps to save the energy of drying process.

The outer body is also polished to 180-220 grit finish with step-less body for GMP model tray dryers.
