Abstract
The present invention provides a filtering device for a food waste treatment apparatus. The filtering device includes a hygroscopic filter unit (240) which is connected to a drying furnace (202) of the food waste treatment apparatus and removes water from gas generated by the treatment of food waste, and a deodorization filter unit (230) which is connected to the hygroscopic filter unit to filter the gas supplied from the hygroscopic filter unit. The hygroscopic filter unit may be integrated with the deodorization filter unit. The present invention can remove water from gas generated from the food waste treatment apparatus and thus prevent pollution of the surroundings of the apparatus and corrosion of the apparatus. Furthermore, by the virtue of the dehumidifying function, the present invention can enhance the efficiency of a deodorization filter and reduce the frequency of replacement of the deodorization filter, thus reducing the maintenance cost.
