1 piece (MOQ)
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.

FEATURES • HIGH AUTOMATION • LOW MAINTENANCE • CONTINUOUS OPERATION • LOW OPERATING COST OPERATING TEMPERATURE :- 60°C to 1OOO°C. CAPACITY :- 5 TPD TO 150 TPD SIZE & MOISTURE :- Capable of Handling different product particle size & moisturecontent. SYSTEM Drying / cooling is achieved by passing the material to be processed through a rotating cylinder through which also passes a current of tempered air. Lifters/flights or louvres in the case of rotary louvre dryer, are fitted to the Internal surface of the cylinder to give intimate contact between product and drying or cooling air stream. In Rotary Louvre dryers the material IS not lifted and dropped through the drying air stream, therefore less product breakdown occurs. Rotary Louvre dryers can also be arranged for multi-stage drying, or drying and cooling in one Unit. DRYER PRINCIPLE Co-current Flow Rotary Cascade Dryers, sticky and heat sensitive materials, since the wet material IS exposed to the highest temperature gases, the initial heat transfer rate is very high, rapidly evaporating surface moisture. The Immediate and dramatic fall in gas temperature prevents a sudden Increase in the matenal and shell temperatures. The final product is in contact with the lower temperature gases enabling the moisture content to be readily controlled thereby avoidrnq over-drying. Counter-Current Flow drying in a Rotary Cascade Dryer gives lower product moisture than co-current flow for a given inlet temperature. However, its use with heatsensitive rnatenals IS limited since the dryed product comes into contact with the heating medium at its highest temperature. It is suitable for application where an extremely low moisture content is required or where a higher product temperature is anadvantage. HEATING MEDIUM Gas. Diesel, oil, electric, stream. The drying gas are provided from either a direct fired furnace or an indirect heat exchanger within the range 100 to 1000 C using solid, gaseous or liquid fuel. Only products of combustion or indirectly heated gases enter the Rotary Cascade Dryer. This prevents surface contamination while reducing the risk of damage or fire when handeling more sensitive materials. A two fan balanced draught system IS used to provide the maximum degree of control & flexibility. In arrangements and the drying gases are provided by a locally mounted burner projecting the flame down the centre of the dryer through which the material cascades. This design gives even greater thermal efficiency due to the higher temperature differential, the direct flame contact and the radiation effect, when processing materials which can withstand high gas temperatures without deterioration. CONSTRUCTION Carbon, Stainless or custom alloy steel plate, with external reinforcing bands for fitting of tyres and drive rings. Flights and lifters or louvres are welded or bolted internally. Confifuration is determined by application. DRIVE Drum is rotated by an electric motor through V-belts, gearbox, pinion and either heavy duty chain to a chainwheel or spur gear drive ring bolted around the dryer drum. For high temperature operation, tangent plates are utilized to allow for differential expansion. CLOSURES & SEALS Ends of drum may be enclosed by carbon or alloy steel fabricated end plates or hood With Inlet/outlet chutes and suitable seals Note : Dimensions and the other data of the Rotary Dryers depend on the material properties, water content. dryness, drying capacity, etc. The values of motor horsepower given in the table are those required to rotate the rotary dryer alone. The figures do not Include the horsepower requirements to operate the exhaust, burner material feeder etc.
