Drying Technology

Wood Pellets

Astec uses its own design of hot-oil tube dryers instead of the traditional air-swept rotary dryers which have inherent direct hot gas exposure to highly flammable wood dust and chips. All of the off-gases from the drying process are conveyed to the combustion chamber of the hot oil heater where any volatile organic compounds (VOCs) and fugitive wood dust are consumed, not released. This means that even very large Astec pellet plants may be operated without Regenerative Thermal Oxidizers (RTOs).

Astec uses rotary hot oil tube dryers that prevent material damage and assures even drying. This method keeps the drying chips in an almost oxygen-free environment. Very little oxygen means very little chance of fire or explosion.
