Vasai East, Mumbai, Maharashtra

The complete drying plant compromises Rotary Cascade Dryer, Air Heater, Dryer Inlet Hood, Exhaust Hood, Exhaust Air Fan & Ducting and all necessary Controls.

• Duty : To Dry about 750 Kg/hr. of Chilly Flakes from approximately 20% initial moisture to 8-10 % final moisture.
• Dryer Drum : 3 Ft Diameter X 28 Ft. long dryer drum fabricated in Stainless Steel plate SS-304 , with internal flights and lifters fabricated and bolted to Stainless steel angle sections welded to the shell plates to ensure adequate contact between the drying air and the material being processed. The drum is fitted with two cast or forged steel tyres, mounted on carbon steel spacer blocks fitted to a reinforcing band. The tyres run on four cast or forged steel support rollers shrunk fit on steel shafts with shaft mounted spherical roller bearing plummer blocks. A segmental cast steel chain ring is fitted around the periphery of the dryer drum.
• Support Frames: The complete dryer drum assembly is supported on two fabricated carbon steel roller support frames, the feed end support frame carrying the locating roller assemblies. Both roller support frames are fitter with safety guards.
• Drum Drive: The dryer drum is driven by a T.E.F.C. electric motor through V-belt drive, gearbox, pinion and chain to the drum drive chain wheel. Motor, gearbox and V-belt, etc. are mounted on a fabricated carbon steel baseplate. All drives are completely enclosed in suitable safety guards.
• Air Heater : The drying air is provided by means of Electrical Operated, firing into a refractory lined carbon steel combustion chamber connected to the dryer inlet end hood. It can also be operated with Electrical Heater of 30 KiloWatts rating.
• Inlet End Hood :The inlet end of the drum is totally enclosed with a Stainless steel fabricated enclosure, complete with labyrinth seal. and stainless steel material inlet chute. The inlet hood is supported by a suitable rolled steel section support structure.
• Outer End Hood : The outer end of the drum is totally enclosed with a carbon steel fabricated hood complete with inspection access door, exhaust air outlet chute. A labyrinth type flexible seal is fitted to the rear hood plates around the drum opening. The outlet end is supported by a suitable rolled steel section support structure.
• Exhaust Air Fan : The exhaust air is drawn from the dryer by a centrifugal fan, complete with electric motor, V-belt drive and drive guard.
• Exhaust Air Ducting : The exhaust air from the dryer is conveyed via a Stainless steel duct from the outlet end hood to the cyclone and from the cyclone to the exhaust fan. A manually operated butterfly type valve damper is fitted in the exhaust duct between the cyclone and exhaust fan.
• Control System : Inlet air temperature is measured by means of a thermocouple located in the inlet end hood connected to a temperature indicator/recorder. Exhaust air temperature is measured by a thermocouple located in the exhaust air duct connected to a temperature indicator/recorder. The Electrical output is controlled by means of a suitable Thermostat via a suitable transmitter from either of the two temperature indicator controllers. All necessary motor control gear, relays, overloads, etc. and temperature indicators/recorders are housed in a carbon steel control cabinet which will be prewired for correct sequential star-up and operation of the plant.

We are a preferable exporter, manufacturer of Tray Dryer in Vasai, Maharashtra, India. Tray dryer is an Insulated Chamber within which hot air is on continuously circulated. Forced convection heating takes place to remove moisture from the solids placed in trays.Trolleys containing trays are dragged inside the dryer. Electrical heating elements are used to generate heat inside the dryer. Tray drier is an Insulated Chamber within which hot air is connuously circulated.
