New AVM Systech Private Limited

In Tube Bundle dryer, tube bundle is rotating inside a stationary housing. Heating Media is passed through the tubes of Tube Bundle. Material to be dried is fed into the stationary dryer housing at a suitable location at one end. The material gets lifted up showered on tubes with help of specially designed lifters provided on tube bundle periphery. The material gets dried by conduction heat transfer discharged from the other end. AVM offers customized configurations of Tube Bundle Dryers.

AVM offers customized configurations of Agitated Rotor tyep Paddle Dryers. When used as Dryer / Heater, Heat is supplied to a jacket of the stationary cylindrical housing. The material to be dried is kept in agitation by means of a specially designed rotor. Rotor is specifically configured depending on material characteristics can be Screw / Ribbon / Paddle / Plough / Anchor / Special Type etc. Heating Media can be Steam / Hot Oil / Hot Water / Thermic Fluid etc. Solvent Recovery option is also possible. For using as cooler, suitable Cooling Media can be circulated in the jacket.

The material to be dried does not come in direct contact with the drying media. The Indirect Rotary Dryers comprises of an assembly of two concentric rotating shells supported on rollers/tyres and driven by means of suitable drive arrangement. Feed is admitted through suitable feeding mechanism like Screw feeder/Flap Valve into the dryer through stationary feed hood. The drying media is admitted through the inner shell travel towards discharge end again returns towards feed end through specially designed return gas passages on the inside of an outer shell. The inner shell is also provided with suitable radial lifters. These lifters along with return passages geometry is designed for the showering of feed material. Shell inclination rotating speed facilitate forward movement of the material towards discharge end providing required residence time. Drying takes place by heat transfer to the showering material by direct contact with inner shell return passages. Product is discharged from the stationary hood through suitable equipment.
