Energy Saving/Thermal Facility

MAIN Business Energy Saving/Thermal Facility

Indirect Heating Dryer

Dryer operated by indirect heating span. by contacting the outer surface of steam tube inside drier

Features
  • · Less energy consumption due to high heat insulation effect from drying by conductive and radiant heat
  • · due to the characteristics of direct heating dryier, can minimize the size of air pollution prevention facility
  • · Less thermal denaturation by contacting heat source of relatively low temperature
  • · Dry various products and volumes according to application of diverse supplementary equipment

Direct Heating Dryer

Dryer operated in direct contact of heated air and wet product

Features
  • · Products are dried by momentary contact while being transported within heat source (air flow) for several seconds
  • · Fast heat delivery rate from heat source (air flow) and effective in evaporation of moisture in solid particles
  • · Suitable for products with low heat denaturalization
  • · Can save energy by recycling waste heat
