Description

Food waste disposal device {APPARATUS FOR DISPOSING FOOD WASTE}

The present invention relates to a food waste processing apparatus, and more particularly, to a food waste processing apparatus for decomposing food waste generated at home using microorganisms and regenerating and using as needed.

Recently, as the problem of environmental preservation or protection has emerged, interest in the disposal of food waste generated in homes, restaurants, and the like has increased.

These food wastes are collected in a separate processing container and collected and disposed of in a separate processing container, and when the food is stored at home or in a restaurant, and collected in a separate processing container, a distinctive smell of food waste occurs. There is a problem that is leaked to make the surrounding dirty or polluted.

On the other hand, in order to process the food waste collected as described above, conventionally a method of embedding or incineration in the ground was used.

The landfill method causes severe odors, and leachate is generated, causing serious environmental pollution such as polluting ground water as well as surrounding soil.

The incineration method requires a lot of incineration energy due to the nature of the food waste with a lot of costs, and there is a problem of generating toxic gases to the human body when incinerated.

In addition, both the landfill method and the incineration method are difficult to secure and establish a new site due to the above-mentioned problems, and it is difficult to maintain the existing facility.

Accordingly, in recent years, a crushing method for crushing food waste to discharge to the sewage, a drying method forcibly dried by a drier, a fermentation method for recycling to fertilizer or feed using a fermenter, food waste using microorganisms An extinction method for extinguishing is proposed.

In the case of the grinding method, there is a problem that a separate sewage treatment facility must be installed, and the drying method and the fermentation method also require an enlarged facility, as well as an unsanitary problem in the collection and transportation process, There is a problem of having to reprocess the finished secondary product.

Therefore, without the need for a separate collection process, it is recommended and used to extinguish and dissipate by using microorganisms in the home or business where food waste is generated by itself.

However, the conventional food waste treatment apparatus using microorganisms is not suitable for home use because the structure is complicated and the size is large because the shredding apparatus for shredding food and the stirring apparatus for activating microorganisms are required, respectively. By discharging the contaminated water generated as it is through the sewer, there is a problem that adversely affects water pollution, as well as the generation of odor.

The present invention has been made to solve the above-mentioned problems of the prior art, the object of which is to separately remove the water and odor from the food waste, while decomposing, extinction or fermentation of the food waste from which water is removed to some extent, It is to provide a food waste processing apparatus capable of moving and discharging the processed food waste processed materials as necessary.

In order to achieve the above object, the present invention provides a food waste treatment apparatus using microorganisms, the device is a housing having a storage space therein, the connection port and the connection port is installed on the housing so as to communicate with the storage space side A food waste inlet having an automatic opening / closing discharge door located at a lower portion thereof, a water detection sensor disposed at a predetermined position of the upper portion of the discharge door to detect the water contained in the input food waste, and adjacent to the discharge door to the outside of the housing; A stirring drum formed in the storage space and communicating with the drainage port, which is discharged to the outside after being decomposed, fermented, or extinguished by using microorganisms while loading and stirring the water-removed food waste dropped through the discharge door. And, a control unit for controlling the opening and closing of the discharge door according to the signal of the water detection sensor Characterized in that it also.

In one embodiment, the inlet is characterized in that the canter lever type of rotating material.

In one embodiment, the stirring drum is characterized in that the sliding in and out inside the storage space.

In one embodiment, the stirring drum is characterized in that it comprises a drive shaft connected to the drive source, and a stirring screw arranged in the longitudinal direction of the drive shaft.
