Our company manufactures aerodynamic dryers relating to the type of dryers with "fluidized bed". They are very effective and are designed for continuous drying of fine moist materials. The fraction of drying raw material should be 0-5mm. Best of all they are used for drying raw materials of organic origin. This can be sawdust, wood chips, bark, shavings, straw, other comminuted vegetable waste, and also lignin, peat, and other materials. Such materials are commonly used in the production of pellets and briquettes. This is because they are cheap enough energy source and are often the waste of other production. Therefore, the drying goal is to increase their heat of combustion and preparation of raw materials with optimum moisture to produce quality pellets and briquettes, in their manufacture. Also aerodynamic dryers have been successfully used in other industries which needs to dry wet materials quickly and efficiently.

Our aerodynamic dryers allow to reduce initial moisture content of 60% in raw materials at the inlet to the outlet of 10-12%, giving 400-800 kg of dry product per hour, depending on the capacity and size of the equipment structure. In larger initial humidity performance decreases.

The very process is quite simple. The raw material falling into the drying chamber from the hopper is is picked up by a stream of hot air, preheated in a heat exchanger, and turned in a so-called "fluidized bed". The drying of the product to the desired humidity occurs by creating the required height of "fluidized bed". The material is circulating in the chamber as long as the lighter dried particles are carried into the cyclone by gases. There dried material is removed through the bottom. Drying air is heated to 120-150 ° C in the heat exchanger, which operates on the same raw materials as wood chips, shavings and other wood waste, firewood, at a rate of 60-80 kg/h.

Thus, due to the low temperature of the drying agent, aerodynamic dryers are fire safe but very effective.
