The present invention relates to a device for processing food waste, and more particularly, to a food waste processing apparatus that can be stored refrigerated after pressing the food waste to prevent corruption.

Food waste is an essential part of human life. Especially, food waste generated in a culture zone where soup or steam is developed, such as Korea, contains a large amount of water, so when left at room temperature, it will rot.

Such conventional food waste is treated by landfilling, but when landfilling, leachate is generated, which contaminates soil and groundwater of landfill, and wastes resources that can be recycled and used as compost or fertilizer. Therefore, various efforts are being made to treat food waste and recycle it into compost or fertilizer. As a part of this effort, a device for treating food waste has been proposed primarily in homes or food retailers that produce food waste.

In the conventional food waste treatment apparatus, the food waste is separately stored by crushing or dehydrating, and then dried to be regenerated or reclaimed as compost or fertilizer.

However, the conventional food waste treatment apparatus has a problem in that, even if dehydration is performed well, the food waste is decayed while temporarily storing the food waste indoors by moisture remaining in the food waste.

In addition, the conventional food waste disposal apparatus has a passage for discharging when washing dishes because a passage for discharging the water to wash dishes and a passage for discharging water generated when crushing and squeezing the food waste are integrated. There is a risk that the water will overflow into the food waste storage space. In addition, there is a problem that the odor generated from the food storage space is discharged during dishwashing to cause discomfort. In addition, the conventional food waste treatment apparatus does not have a means for sealing the crushing unit when crushing the food waste, there is a fear that the user may be injured hand.
