We supply Tray Dryer that is adequately designed by our designers and adroit personnel who take every care in the fabrication of a durable and highly efficient range of machines. Available in various models such as 12 trays, 24 trays, 48 trays, 96trays, these are high in performance and low on maintenance. The major problem in calculations on real dryers is that conditions change as the drying air and the drying solids move along the dryer in a continuous dryer, or change with time in the batch dryer. Such implications take them beyond the scope of the present book, but the principles of mass and heat balances are the basis and the analysis is not difficult once the fundamental principles of drying are understood. Obtaining adequate data may be the difficult part. In tray dryers, the food is spread out, generally quite thinly, on trays in which the drying takes place. Heating may be by an air current sweeping across the trays, by conduction from heated trays or heated shelves on which the trays lie, or by radiation from heated surfaces. Most tray dryers are heated by air, which also removes the moist vapours.

• 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 insulated with minimum 50 mm thick glass wool insulation and caddied with s, s, polished sheets
• Fresh air inlet through 20 micron pp cloth filters and a adjustable air outlet flap and a door at the front
• Explosion proof door is locked with the help of spring loaded ball latches with suitable pressure.
• To prevent leakages door lips are having neoprene rubber gasket

Finishing-

• Designed and manufactured as per GMP standard
• Aesthetic look
• Buffed externally to 150 grit matt finish
• 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
• The temperature is indicated and controlled by a Digital Temperature indicator cum controller over full range of heating load
• The total heating load for it will be 12 Trays Dryer - 4 KW 24 Trays Dryer - 6 KW 48 Trays Dryer - 12 KW 96 Trays Dryer - 24 KW
• To prevent the heaters from becoming red hot these are inserted inside tubular pipe
• The terminals of the heaters are brought outside the dryer to make it safer for operations for solvent based products

Vacuum Tray dryer is the most commonly used batch dryer. They are box-shaped and loaded and unloaded via a door (two doors on the larger models). Inside are several heating plates mounted one above the other on which the product is placed in trays. The bottoms of both heating plates and trays should be as smooth as possible to permit optimal heat transfer between plates and product. The medium flowing through the heating plates is water, steam or thermal oil. The distance between the heating plates is determined primarily by the surface loading and the foaming of the product. To void retrograde condensation the cabinet walls are indirectly preheated by the heating plates. Next, the product is introduced and heated at atmospheric pressure. Only after all individual product trays reach the same temperature the cabinet is evacuated and drying can start. The preheating phase is very important in order that the drying curve and the foaming of the product is identical throughout the cabinet. During the main drying phase the vacuum is in the range of 40 to 80 mbar abs and in the final drying phase vacuums of only few mbar abs are reached. Heating temperatures are normally in the range between 800C and 1100C. Depending on product and surface load, drying takes from a few hours to 1 to 2 days. For some products the vacuum and temperature profiles are automatically controlled in order to prevent a pass over of the critical product temperature.

The dimensioning of the vacuum system is an important factor in the design of drying cabinet systems. If for example vigorous foaming of the product is desired, evacuation to the operational vacuum level must take place very quickly. Vapors produced during drying are taken out direct, or via a steam jet compressor to a surface condenser in which the vapors condensate. The non-condensable vapors are extracted by the vacuum system.

On completion of the drying, the product can be cooled by circulating of cooling water through the heating plates.

Features:

• Dedicated fluid heating and circulating systems. These can be steam or electrically heated. Fluid heating systems are available for water as well as thermic fluid (for temperature requirements above 95 oC)
• Validation ports and nitrogen purge nozzles
• Can be designed to customers specification requirements
• Steam sterilisable models available
• Double door loading available for large models
• Halar lined internals for corrosive applications

Our fluid bed dryer consists of a simple drying unit and helps in the conversion to a granulation or coater when optional packages are incorporated. These dryers are available in standard pneumatic logic and sophisticated computerized controls and are also offered in Steam heated Model. Our dryers provide simple solution to dry products and are high in performance as compared to the conventional drying method in tray dryers, which is rather inadequate & troublesome.
