Moving Bed Continuous Dryers

The low temperature continuous dryer is a highly efficient drying system that can be used in different industry segments and product lines. The products include for example wood chips/ Blocks , Cotton Stalks , Baggasse, etc. of size from 15 mm to 45 mm . No need to fine-grind the material to be dried. Drying time is sufficiently long for also coarse particles to dry.

It is a counter flow design dryer in which Air is pushed from the bottom of the dryer, which drives the moisture from the bottom of the material to the top.As the material moves through the dryer, large volumes of steam escape through the top , leaving the dried materials behind.

Drying system is a self-contained unit, including the in feed and out feed, completed with automation.Material inside the dryer is moving with gravity, so operation does not need much mechanical power.Different heat sources can be used for heating the drying air, such as ”waste energy” of power plant, smoke, etc.

Space usage is optimal due to vertical construction, which makes it easier to place the device in existing process environment.Construction will be easily scaled and dimensioned for different capacity ranges. Biomass flow from few to many hundreds of cubic-meters per hour can be handled.

Working with low temperature (drying temperature 60 – 120°C), the dryer dries the product gently and homogeneously. Low drying temperatures (120°C maximum) keep volatile organic compound and particle emissions to a minimum, making it possible to meet even the most stringent environmental permit limits without having to treat the exhaust air.

Another decisive advantage are the low emission. Besides, the risk of fire and explosion is excluded. The temperature of the low temperature dryer generated by waste heat from power plants, which leads to significant energy savings.

Silent feature of Continious dryer

  1. Drying is completed at low outlet drying temperatures, giving high energy utilization efficiencies.
  2. High drying efficiency and low energy costs.
  3. Continuous processing .
  4. Low operator overheads and minimum maintenance costs.
  5. Capable of processing high capacities in a relatively small amount of space.
  6. Ease of installation.
