Dried chicken manure

Dried and pelletized manure


With the help of the Dorset Dryer, poultry manure can be dried and converted either into organic fertilizer or fuel.

With the help of the Dorset Dryer, poultry manure can be dried throughout the year and converted either into organic fertilizer or fuel. The required warm air for the drying process can for instance be derived from farmhouse air, or it can be residual heat from the generation of electricity. Dried poultry manure is an excellent and frequently used plant nutrient, both in a dried form and as a pellet.

Dorset dryers are frequently used for drying chicken manure with the help of warm air from the farmhouse. Most of these installations do not use pre-drying in the farmhouse, which leads to substantial savings in electricity costs. The air from the farmhouse that is utilized usually has a temperature of approximately 20°C. This is sufficient for drying the produced manure. Still, the higher the temperature and the lower the air humidity, the better the drying process will be. Poultry manure, either in a dried form or as a pellet, is an excellent and very popular plant nutrient.

The Dorset drying system has been certified by the government of the Netherlands as a technology that limits fine particle and ammonia emissions. The particulate content of farmhouse air is reduced (approx. by 70 – 80%). It is possible for poultry farms to receive a subsidy for this.

Why dry poultry manure?

  • Making good use of residual heat during the entire year
  • Lower storage and transport costs
  • New sales and utilization possibilities
  • Dust filtering
  • hygienization and reduced emissions/odours
