The present invention relates to a treatment apparatus for treating food waste generated in a home or a restaurant, more specifically, it is installed under a kitchen sink and shredded while dehydrating moisture contained in food waste by a compression process. And it relates to a food waste processing apparatus for crushing and storing the crushed food waste while drying again while purifying the dewatered sewage.

In general, food waste generated in homes and large food establishments contain a large amount of water, so when landfilled with general waste, the food waste decays, leachates and odors become contaminated, contaminates groundwater and breeds pests. This causes environmental pollution.

Because of this, in recent years, to improve the problems caused by food waste, general household waste, food waste, and recyclable waste are separately collected and collected, where food waste is dehydrated to some extent in the home or restaurant. It is placed in a food waste bin so that food collection vehicles can be collected.

In the conventional case, the food waste is collected from the food holder installed in the drain of the sink in the process of washing dishes or cooking food, and when food waste is collected to some extent in the food holder, the food waste is transferred to the food waste bin and processed.

However, the food waste collected in the food holder of the sink causes decay as time passes, thereby causing a bad odor, and the food waste that is transferred to the food waste bin also decays over time, causing severe odor. On the other hand, there were problems creating conditions for pests to multiply.

Therefore, in order to improve such problems, a technology for reducing the volume of food waste and reducing corruption and odor by dehydrating and crushing food waste introduced into the storage space provided under the kitchen sink through the drain hole of the kitchen is registered in Korea. Utility Model Nos. 20-0317179 (Household Food Waste Disposal Devices) and 20-0384872 (Food Waste Disposers) have been proposed.

The prior art is a housing assembly is installed in the storage space under the sink in communication with the drain of the sink, a screw is rotated by the drive of the motor is installed inside the housing assembly while drainage to drain the sewage dewatered from the housing assembly to the sewer The line is connected and installed, the food waste dehydrated and crushed through the compression process by the rotation of the screw inside the housing assembly consists of a structure placed in the collection box installed on one side.

However, the prior art reduces the volume by dehydrating and crushing food waste in the compression process by the rotation of the screw, while reducing the occurrence of decay and odor, but a small amount of moisture even in the dehydrated food waste Because of the high temperature, such as summer, corruption occurs easily. In particular, sewage dehydrated from food waste contains a large amount of salt and oil, which contaminates sewage, making it difficult to purify sewage. It is happening.

The present invention is a technology devised to solve the problems according to the existing food waste treatment apparatus as described above, is installed in the storage space under the sink and crushed while dehydrating the water contained in the food waste by the compression process, the dehydration and shredded It is a main object of the present invention to provide a food waste treatment apparatus for crushing and storing food waste while drying it again while purifying dehydrated sewage to be discharged to sewage.
