Pneumatic Dryers

The Pneumatic Dryersare one of the most widely used Dryers in recent times. It is also known as Flash Dryers.


The large surface area for heat and mass transfer and the high convective heat and mass transfer coefficients, which take place at these units, result in high drying rates and as a result, high drying capacity. The size of particulates to be dried is usually in the range of 10–500 mm. One of the features of these types of dryers is the relatively short contact time between the hot air and the particulate materials (0.5–60 s) at the drying section. Because of this the material temperature stays always low in the drying process.


The simple flash drying system includes seven basic components: the heater, the wet material feeder, the dryer and crusher, the cyclone, the jet filter and a exhaust fan.


Components

  • Screw: Diameter is determined by capacity. Spiral stainless steel drying of food products.
  • Feeder Motor: Specially selected by the size of the machine.
  • Speed Control Device: To control the feeding capacity by using control board.
  • Function: The product mixing and more rapid drying process was made by crushers. Crushers and crushing on the mixing blades are specially designed product.
  • Mixing Blades: carbon steel sheet laser will be produced as predicted. Food products can be manufactured in stainless steel material.
  • Shaft: I can be can be made for the stainless steel material for food products.

Rotary Motor: specially selected by the size of the machine.

  • Extras: The Crusher adjustment system will be balanced.
  • Burner: Needed Energy of the drying is prepared at the burner unit.
  • Function: Cyclone is used to separated product from air.
  • Air lock engine: Engine power and speed are selected according to the product.
  • Bag filter: Bag filter is used to seperate fine powder from air. usualy below the th product size of 200 micron.
  • Control Panel: It is used to control all of system.


Application

It is used to get needed air for drying operation. Air pressure and flow are chosen according to dried product, inlet moisture, outlet moisture and etc.
