Abstract
Provided are a continuous drying apparatus and method. The apparatus includes a combustion chamber, a heat exchange chamber, a filter, a mixing chamber, and a drying chamber. Biomass to be dried is loaded into an upper end of the drying chamber and falls on a rotating plate at a bottom of the drying chamber. Heated gas from the combustion chamber is mixed with recycled gas output from the drying chamber, and with recycled gas output from the heat exchange chamber, is filtered and is directed to the mixing chamber. Gas circulates within the mixing chamber and is directed into a lower end of the drying chamber at a drying temperature. The biomass loaded into the drying chamber is dried by the gas, and is extracted off the rotating plate.
Claims8
A continuous drying apparatus, comprising:
- a drying chamber, a filter, a combustion chamber, a heat exchange chamber, a mixing chamber, and a chimney, wherein:
- the drying chamber comprises an opening through which biomass is loadable and an extractor which extracts biomass therefrom;
- the drying chamber receives gas at a drying temperature from the mixing chamber and outputs recycled gas, which is directed to the filter, and exhaust gas;
- the filter filters the recycled gas from the drying chamber, the heat exchange chamber and the combustion chamber and outputs filtered gas to the drying chamber;
- the combustion chamber heats gas and outputs heated gas to the heat exchange chamber;
- the heat exchange chamber enables an exchange of heat between filtered gas from the filter and heated gas from the combustion chamber and outputs gas to the mixing chamber;
- the mixing chamber comprises at least one fan which directs the gas at a drying temperature into the drying chamber.
