Tray dryer working principle
A trader is a conventional drying in equipment with enclosed insulated chambers and trees placed on top of each other in a trolley the trials are used in processes were drawing in heating are crucial part of the industrial manufacturing process such as in food products girls dyestuff and chemical manufacturing among others the material to be dried are either solid or wet and are placed on the trays.
The heats the trace is transferred via hot air circulation by a steam in a radiator coil or electric heater the transfer of heat as well as the proper circulation of heat is facilitated by the installed low of fans additional the equipment has a control panel for temperature control as well as the parameter of its outside equipment and assist in the functioning.
The basic working principle of this incredible machine is container circulation of hot air in the tray dryer moisture is removed from the solids that are placed in the tray by forced convectional heating the most a is removal in conducted partially but in a simultaneous fashion.
Initially the wet solids are loaded into tray and the trays placed in the dryer chamber there is then the introduction of fresh air through the inlet the air passes through heater where it is heated up.
The objective of heating is to ensure that the heated is 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 2 to 5 metres per second the turbulent flow reduces atmospheric partial vapour pressure in thickness of the layer of the air boundary.
The heated at pics of water during water evaporation from the surface there is a definition of water from the interior of the solids by a capillary action all the above mentioned event happens in a single pass of air this is a short contact time and only a small amount of water is present in a single pass and as a result this charge air into the rate of 80 to 90% is circulated back through the fans and only a maximum of 20% off fresh air is introduced.
The moisture discharge occurs through the outlet therefore uniform airflow and constant temperature over the solid material can be maintained for achieving uniform drive in the event the material to be dried are wet granules such as in capsules or tablet drying. drying in drawing is continued until the desired moisture content is attend the completion of drying process the drying trucks entrees are pulled out on the chambers and taken to the trade dumping station
Tray dryer offered by vmi includes Tray Dryers with Steam systems, Tray Dryer with Electrical Hot Air Heater base, Tray Drier suitable for Chemicals, Dye stuff, Pharmaceutical, Food Products, Colours with Mild Steel, Stainless Steel Tray Dryer is used for the best drying results in conventional process. Tray dryer with Hot air and Steam base supply with double walled cabinet with Single or Two doors as per customer demand. Hot Air Dryers two walls is filled with high density fibre glass wool insulation material to avoid heat transfer. Tray dryer Doors are provided with gaskets. Stainless steel trays are placed on the movable trolleys. Tray Dryer with Operating control panel board, process timer, Digital temperature controller cum indicator etc. the model is available with different ranging from 6, 12, 24, 48, 96, 192 trays.
Tray Drying Ovens are used for drying of pharmaceutical powders, granules, Pigments, Food, Bakery, Electrodes, Chemical, and Plastic etc in an effective and economical way by hot air re-circulation.
Tray dryer is an enclosed insulated chamber in which trays are placed on top of each other. Heat transfer is done by circulation of hot air by electric heaters or any other heating media. Blower fans are installed inside to ensure proper circulation and transfer of heat.
