Drying

Vapco engineers supplies engineering services and complete process plants and components for drying of products to customers in the industries of distillery, food and dairy, chemicals, pharmaceuticals and environmental protection. Drying is one of the most widely used unit operation in the processing industries. Vapco offer a range of dryers for handling fluid, paste, and moist powder, particulate and granulate feeds.

1. Steam tube dryer:

        a) Rotating shell
        b) Fixed shell

2. Flash dryer

3. Rotary cascade dryer

4. Spray dryer

5. Belt dryer

6. Rotary vacuum dryer

7. Paddle dryer


1. STEAM TUBE DRYER

Principle of Operation:

  • The material is fed continuously at uniform rate and is tumbled & showered by rotation of cylinder.
  • In a stream of hot air, when moisture gets transferred to the air, rendering the product progressively dry as it travels the length of the dryer
  • The humid air is exhausted into atmosphere via a dust collection system to trap fines escaping with the exhaust air.

  • Advantages:

  • Low temperature, indirect drying
  • Suitable for free flowing granular feeds.
  • High thermal efficiency
  • Minimal process air flow
  • Relatively low emissions
  • Adaptability to fluctuating feed rates & moisture contents of products

  • Applications:

  • Germ/ Fiber
  • DDGS / Spent Grain
  • Fly ash
  • Agro products



































  • 7. PADDLE DRYER:

    Principle of Operation:

  • Paddle Dryer are highly efficient, mechanically agitated, indirect heat transfer devices that add or remove heat from a process mass.
  • Dual counter-rotating shafts with unique intermeshing wedge shape paddles produce intimate mixing and optimize heat transfer.
  • The use of hollow paddles for heat transfer results in a compact machine. The heat transfer medium: steam, oil, thermal fluid, water, or glycol is isolated from the process mass.

  • Advantages:

  • Dryer size is minimized, due to the large heat transfer area per volume.
  • Slurry with high viscosities can be treated.
  • The wedge shaped paddles goes into the powder to enhance contact to the heat transfer area.
  • Heat transfer coefficient is relatively high due to the good mixing.
  • Residence time distribution is sharp and the powder is uniformly dried.
  • Available under the vacuumed condition as well, for materials which are sensitive to high temperatures.

  • Applications:

  • ETP sludge
  • Magnesium carbonate
  • Magnesium sulphate
  • PHBA
