Tray Dryer is of robust construction built on formed angles of 3mm thick sheet and suitably reinforced with angles and sections. The dryers external walls are manufactured from 1.6mm thick Stainless Steel sheets of 304 quality. 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 glasswool 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.
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.
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.
24 Trays Dryer – 6 KW
48 Trays Dryer – 12 KW
96 Trays Dryer – 24 KW
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 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.
Racks And Trolleys
Racks are provided for trays inside the Dryer. They are of fixed type for 12 and 24 Tarys Models. For 48 and 96 Trays Models. Racks are provided with wheels to slide them in and out of the Dryer. An additional S.S, trolley for Racks for outside movement can be provided on request

A tray dryer is a convectional drying equipment with enclosed insulated chambers and trays placed on top of each other in a trolley. The driers are used in processes where drying and heating are a crucial part of the industrial manufacturing process such as in the food products, pharmaceutical, dye stuff, and chemicals manufacturing among others. The materials to be dried are either solid or wet and are placed on the trays.
The heat through the trays is transferred via hot air circulation by a stream in a radiator coil or electric heater. The transfer of heat, as well as the proper circulation of the heat, is facilitated by the installed blower fans. Additionally, the equipment has a control panel for temperature control as well as other parameters fixed outside the equipment and assist in its functioning.
The basic working principle of this incredible machine is the continuous circulation of hot air. In the tray dryer, moisture is removed from the solids that are placed in the tray by a forced convectional heating. The moist air is removal is conducted partially but in a simultaneous fashion.
Initially, the wet solids are loaded into the trays and the trays placed in the dryer chambers. There is then the introduction of fresh air through the inlet, the air passes through the heaters where it is heated up.
The objective of the heating is to ensure that the heated air reaches the wet solids on the tray, therefore, the fans in the tray dryer are used to circulate the hot air at a speed of two to five meters per second. The turbulent air flow reduces atmospheric partial vapor pressure and the thickness of the layers of the air boundary.
The heated air picks up water. During water evaporation from the surface, there is diffusion of the water from the interior of the solids by a capillary action. All the above-mentioned events happen in a single pass of air. There is a short contact time and only a small amount of water is picked in a single pass and as a result, the discharge air to the rate of 80 to 90 percent is circulated back through the fans and only a maximum of 20 percent of fresh air is introduced.
The moisture discharge occurs through the outlet. Therefore, uniform air flow and constant temperature over the solid materials can be maintained for achieving uniform drying. In the event the materials to be dried are wet granules such as in capsule or tablet drying, drying is continued until the desired moisture content is attained. At the completion of the drying process, the drying trucks or trays are pulled out of the chamber and taken to the tray dumping station.
In totality, the large working space, sturdy construction, controlled temperature, uniform air circulation are the basic principles for the functionality of the tray dryer. it is an equipment with an admirable and exquisite ability to assist in the drying of plastic and chemical powder, electrodes, bakery, food, among other equipment.
