<p>The present invention relates to an apparatus for processing food waste capable of effectively improving drying efficiency, reducing operating cost, and achieving environmental friendliness on the whole by applying a low-temperature drying technique in which food waste is dried under low-temperature conditions. The apparatus for processing food waste according to the present invention comprises: a pulverizing unit for pulverizing food waste; a drying furnace for drying the food waste which has been pulverized by the pulverizing unit; a microwave unit for irradiating microwaves inside the drying furnace; a case to which a waste pulverizing and drying device is coupled; and a water vapor condensing unit for condensing and discharging water vapor having a high temperature generated from the drying unit, wherein the drying furnace comprises a drying casing and a mixing unit for mixing the food waste introduced into the drying casing, wherein on the inside of the drying furnace a heat medium heating portion and a heat medium circulation unit for circulating a heat medium with the heat medium heating portion are installed, the microwaves generated by the microwave are irradiated on one side of the upper surface of the drying casing for heating while the heat medium drying portion installed on the inside of a lower portion of the drying casing heats the food waste, and wherein the heat medium heating portion comprises an external insulation layer installed in a U-shape on the lower portion of the drying casing, an inner wall separated away from the inner side of the external insulation layer, and a heat medium accommodating space which is formed between the external insulation layer and the inner wall for accommodating the heat medium.</p> |
