Drying biomass

biomassa-trocknungdrying-biomass

Through a drying process, moisture can be largely removed from biomass. The result is a reduction in the weight of the biomass.

This leads to a reduction of the processing costs, as well as of the costs for storage and transport. The dried end product is frequently used as a plant nutrient or it can be used as a fuel. This, however, depends on the properties of the biomass that needs to be dried.

Dorset has a lot of experience with drying other biomass materials than the variants found in the menu. Some examples are grass, compost, fats and food residues.

The warm air required for the use of a conveyor belt dryer, can be supplied by the use of either warm stable air or air heated in another way.

The advantages of drying

  • Making good use of residual heat during the entire year;
  • Lower treatment, storage and transport costs;
  • New sales and utilization possibilities.

Advantages of the Dorset Dryer

  • Low energy consumption;
  • Highly compact and flexible;
  • Requires little maintenance;
  • Fully automatic operation without supervision is possible;
  • Remixing frequently makes a pre-treatment of biomass unnecessary;
  • Low dust generation through low air speed;
  • Simple to combine with Dorset air washers.
