Fluid Bed Dryers / Cooler are widely used in the Industry for gentle drying / cooling of free flowing solids.
Perforated plate is used to fluidize the material with the help of air stream. the fluidizer can also be made vibratory to assist the fluidization by imparting mechanical energy. Drying / Cooling media (air / gas) is admitted in the plenum below the perforated plate. Fluidized state enables intensive interaction & of the material & drying / cooling media (air / gas) takes place; hence high rates of heat transfer are achieved. Product residence time can be adjusted through adjustable discharge weir. Product Drying and cooling is possible in single unit .

Rotary Dryers / Coolers are widely used in the Industry for drying / cooling of reasonably free flowing materials. AVM offers Customized Rotary Drying Systems with variety of Configurations.
The rotary dryers comprise of a rotating shell which is supported on tyres or rollers. Suitable drive management is made to rotate the dryers. There are two stationary hood at both the ends, one for letting the air or gas and the other to collect the cooling media. Suitable feeding mechanism is used to admit the feed. The feeding mechanism is governed by screw feeder or chute. The rotating shell in these rotary drying systems is provided with specially designed material showering mechanism like Lifters / Garland Chains etc. The forward movement of the material towards discharge end is provided by the shell inclination & rotating speed. The heat transfer within the shell is responsible for drying of the showering material.Product is discharged from the stationary hood through suitable equipment like Flap Valve / Rotary Valve / Screw Conveyor / Chute.

Direct contact is avoided for the material to be dried in the drying media. Two concentric rotating shells are used to comprise the rotary dryers. The rollers or tyres on which the shells rest are driven by suitable drive management. Suitable feeding mechanism is resorted to let the feed admitted. The feeding mechanism is governed by screw feeder or flap valve. The inner shell lets the drying media to enter and travel toward the discharge end and again it move back to the point of origin. Suitable radial lifters are provided to the inner shell. This special construct is used to shower the feed material. Shell inclination & rotating speed facilitate forward movement of the material towards discharge end providing required residence time. Heat transfer makes the feed material to dry owing to the special construct of the passage. The stationary hood is used to discharge the product through suitable equipment.

Rotary Calciners are used to calcine materials at high temperature. The rotary calciner comprises of rotating shell, rollers or tyres, combustion chamber, stationary hood, screw conveyor and many more tools. The rotating shell is supported on rollers and a suitable drive arrangement is provided. The internals are suitably refractory lined to minimize the heat losses. The combustion chamber produces hot gases which are required for calcination. This combustion chamber is connected to stationary hood and the feed material is fed at the controlled rate. The calcined material flow in counter current fashion within the calciner and gets discharged through discharge hood.

A variety of machines(industrial conduction dryers) like tube bundle dryers, rotatory speed dryers, rotor type dryers are used in diverse industries and can be tailored to meet the client's requirement.
In this dryer, tube bundle is rotating inside stationary housing. In tube bundle dryers, the tube bundle rotates inside stationary housing. The material to be heated is passed through the tubes of tube bundle. The heated material is then fed into the stationary dryer housing at suitable location at one end. Conduction as a means of heat transfer takes place when the material is lifted up by the lifters. The lifters are provided on the periphery of the tube bundle.
AVM offers customized configurations of Tube Bundle Dryers.
In this dryer, the outer shell housing is the fixing point of the tubes and is rotated along with the shell. The circumference of the internal periphery of rotary shell contains the single/multiple rows. Tyres or rollers support the rotary shell and a suitable drive arrangement unit is provided. The feed screw feeds the feed material through the center of one end of the dryer. The circumferential tubes accumulate the steam from a rotating manifold installed towards material discharge end of the shell through Rotary Joint. Condensate is also collected through the same Rotary Joint. The accumulated material gets dried up and is discharged through the other end. The openings serve the dual purpose. It lets fresh air to get into. The vapors are disposed from the feed end. Spiral flight lifters showered the feed material on tubes.
AVM offers customized configurations of Rotary Steam Tube Dryers.
AVM offers custom tailored Agitated rotor dryers. Heat is supplied to jacket of stationary cylindrical housing when used as dryer/ heater. Specially designed rotor is used to put the material to be dried in agitation. Rotor is specifically configured depending on material characteristics and can be Screw / Ribbon / Paddle / Plough / Anchor / Special Type etc. The heating media can be steam, hot oil, hot water or thermic fluid. Provision for solvent recovery option is also provided. Suitable cooling media can be circulated in the jacket when used as a cooler.
Vacuum dryers find extensive usage in the industry for drying a variety of products. These vacuum dryers are perfect to dry heat sensitive products, drying of products in solvents, drying requirements necessitating achievement of very low moisture or low oxygen drying environment in order to optimize oxidation or for explosion prone products. AVM offers custom tailored vacuum drying systems with variety of configurations.
