Dryers:

The dryers, fluid bed dryer, drum dryer, tray dryer are normally used for products with a moderate viscosity. The products that can be processed on dryers includes food products, chemicals, yeast, different types of glues, pigments etc. We manufactured following types of dryers,-
 
 
Special Features:

• Rapid exchange of granules
• Low drying temperature
• Electric or steam heated
• Little space required
• 15 kg. to 250kg batch capacities                                                     
 
 
 
 
 
 
 
 
 
   
Special Features :

• Single piece construction- without flange joints.
• Complete dryer have stainless steel construction with mirror polished   product contact surfaces.
• Edges of all the parts rounded off and only butt welding carried out (by argon arc process).
• Filters bag sealing arrangement by means of inflatable tube.
• Interlocking between filter bag sealing tube and blower motor, and exhaust butterfly valve.
• Product container lifting platform and air cylinder replaced by
pneumatically operated gasket.
• Rapid change of filter bag.
• Built to suit GMP regulations
 
 
 
The feed stock is introduced into a single
or twin steam heated drum dryer in a uniform film by use of variety of feeding devices and arrangements depending upon the material to be dried. The moisture is dried off in less than one revolution and the dried solid is removed usually in the form of a thin sheet/powder by doctor blade.

Advantages:

• Minimum Thermal degradation
• High thermal efficiency
• Fine and spheroidal product
• Minimum labor requirements
• High output
• Continuous process
• Accomplishment of drying in single step,eliminating need for any intermediate concentration processes.

The feed stock is introduced into a single
or twin steam heated double drums in a uniform film by use of variety of feeding devices and arrangements depending upon the material to be dried. The moisture is dried off in less than one revolution and the dried solid is removed usually in the form of a thin sheet/powder by doctor blade.

Air Circulation:

 High Efficiency Axial Flow Fans mounted at most appropriated places in the dryer plays an important part in faster drying and provides uniform air circulation within
the dryer. Axial flow fans are mounted externally on ball bearing pedestals and each fan is driven by independent
1 HP TEFC motor. Air inlet and exhaust outlet dampers are provided on the top roof of the dryer.

Insulation :

The cavity formed in between double wall is heavily insulated with glass wool on all the sides to prevent heat losses from the Dryer.

Control Panel :

Pre-wired control panel consists of digital temperature controller, over current relays, fuses, indicating lamps, push buttons, main isolator switch etc.
