Cabinet Tray Dryer

A cabinet tray dryer is an enclosed insulated chamber in which trays are placed on top of each other in trolleys. Tray Dryer are used where heating and drying are essential parts of manufacturing process in industries such as Chemicals, Dye stuff, Pharmaceutical, Food Products, Colors etc. The material to be dried either wet or solids are placed in the trays. Heat transfer is by circulation of hot air by electric heaters or steam in radiator coils. Blower fans are installed inside to ensure proper circulation and transfer of heat. A control panel to control the temperature and other parameters is fixed outside the dryer. These dryers are available in Mild Steel, Stainless Steel or construction. Tray dryer is used for drying of pigments, food, bakery, and electrodes, chemical and plastic powders.

CONSTRUCTION:

The dryer is of robust construction built on formed angles of 3mm thick sheet and suitably reinforced with angles and sections. The dryer’s external walls are manufactured from 1.6mm thick Stainless Steel sheets of 304 qualities. The internal of the dryer is built of 1.6 mm thick S.S 304 quality sheets. The internal structure is fully TIG welded and all the internals have ground smooth surfaces. It is insulated with minimum 50 mm thick glass wool insulation and Cladded with S,S, Polished sheets. The dryer is having a fresh air inlet through 20 Micron PP cloth filters and a adjustable air outlet flap and a door at the front. The door is explosion proof and is locked with the help of spring loaded ball latches with suitable pressure. Door lips are having Neoprene rubber Gasket to prevent leakages.

Finishing

The design and manufacture of the dryer is of high standard of GMP and has an aesthetic look. It is buffed externally to 150 grit matt finish and internally buffed to 220 grit mirror finish.

Electrical Heating:

The Air inside the Tray Dryer is heated by "U" tube S.S.304 air heaters each of 1 KW. The heaters are fitted on the sides of the dryer to facilitate uniform heating. Maximum temperature attained inside the dryer is 100' C and will be indicated and controlled by a Digital Temperature indicator cum controller over full range of heating load.

Total heating load for it will be

The heaters will be inserted inside tubular pipe to prevent it from becoming RED HOT. The terminals of the heaters will be brought outside the dryer to make it safer for operations for solvent based products.

Air Circulation:

Air inside the dryer is circulated by one heavy duty axial flow S.S.304 or aluminum blower fitted on a shaft of and driven by l H.P. through belt. The special design of the Blower ensures uniform air circulation so that there is uniform air current over the entire charge loaded in the Trolley inside the dryer.   The working of the motor is indicated by lamps in the control panel.

Trays :

Trays will be manufactured from 1.6 mm SS 304 sheets. Its dimensions are 32" x 16" x 1 l/4". The Trays have rounded corners with' mirror finish from inside and outside. SS 316 quality is available on demand.
