Construction:
The dryer cabinet is designed in such a way that air inside the dryer has minimum resistance at all the corners of the dryer. All the sides of the dryer from inside are made with rounded corners with maximum angle so as to have more slippage to air, resulting into less pressure drop across the corners. The outer body is also fabricated with rounded edges without steps from outside to have smooth finish.
Sealing:
The shafts of circulation fans, the inlets & outlets of the radiator coils are sealed by the food grade sealing pads which stops the leakage of the hot air from the drying cabinet.
The leakage of the hot air from such small gaps around the fan shaft or the pipes of radiator coil results into the short circuit of the air circulation. Also they spoil the paint around the shaft and outside the dryer for the dryers in M. S. from outside.
These leakages increase drying time of the product inside the trays of the dryer & some cases the air contamination of air inside the dryer. Thus this helps to save the energy of drying process.

The inlet (suction) of the dryer is provided with 10 micron filter to avoid air contamination. The exhaust of the dryer is provided with either manual or motorized operated damper and can be operated precisely for various positions of the damper from the main control panel board.

The main body of the drying oven is either angled frame with CRCA sheets welded or step less S.S. body with 3 mm thickness from outside as required in GMP models. Two coats of red oxide & one coat of synthetic enamel or epoxy paint are used for the dryer in M. S. from outside. The outer body is also polished to 180-220 grit finish with step-less body for GMP model tray dryers.
