With the development of culinary culture and industry, the amount of food waste (food waste) corresponding to organic waste has increased exponentially. It is emerging as a serious social problem due to its fast decomposition rate, severe odor, high processing cost, and high moisture content.

As a conventional food waste treatment method, a landfill method and a method using a volume-based system were used. However, the landfill method removes various contaminants when the watery food waste along with protein, carbohydrate, fat, and fiber is landfilled. In addition, serious environmental pollution such as air pollution due to generation of harmful gases as well as groundwater pollution due to leachate from landfills is caused, and it has a disadvantage that it is difficult to secure a site. It has a bad odor, a cumbersome treatment and collection process, and a high manpower consumption and work time due to laborious work.

In order to solve this problem, various studies on food waste treatment devices such as drying, pulverizing, and microbial utilization methods for self-disposing of food waste installed in homes and restaurants have been conducted and widely used.

The dry food waste treatment apparatus has disadvantages such as high power consumption, high maintenance cost, severe odor, and high accident risk because it is configured in a manner that the food waste is dried using a heating means to lower the moisture content.

In addition, since the pulverized food waste treatment apparatus is configured to pulverize and crush food waste to a predetermined size using a rotary blade and discharge it through a sewer system, space consumption and installation cost are high, and 80% of the food waste after pulverization is reduced It has the disadvantage of having to collect it again and dispose of it separately.

Recently, various studies have been conducted on a food waste treatment apparatus using microorganisms that can improve the treatment efficiency while solving the problems of the conventional food waste treatment apparatus described above by fermenting the food waste by stirring the food waste with microorganisms. there is.

Manual operation of the opening/closing unit 900 and a function of displaying the current state are further included, and the control of the power transmission unit 600 is controlled by the reprocessing supply mode 701 , the reprocessing repeat mode 702 , and the sequence mode 703 . ) and the solid material transfer mode 704 is controlled to be automatically operated during execution.

Specifically, the reprocessing supply mode 701 receives the storage amount detection value of the storage amount detection sensor 810 and opens the closed discharge valve 112 for a predetermined time when it is higher than a preset storage amount reference value, and the display It is a mode in which text and voice notifying the reprocessing supply to the unit 720 are output.

In addition, the reprocessing repeat mode 702 receives the odor detection value of the odor sensor 820 and closes the reprocessing opening/closing unit 900 when the odor detection value is higher than a preset odor reference value. This is the audio output mode. The reason for configuring the reprocessing repeat mode 702 is to stay in the reprocessing space until the odor of solids and discharged water injected into the reprocessing space 120 is removed. When it is lower than the odor reference value, the reprocessing opening/closing unit is opened.

In addition, in the sequence mode 703, when the discharge valve 112 is opened during the reprocessing supply mode and the reprocessing repeat mode, the reprocessing opening/closing unit 900 located at the uppermost stage is closed for a certain period of time, and the uppermost When the reprocessing opening/closing unit located is opened, the reprocessing opening/closing unit located in the lower reprocessing space is closed for a certain period of time while receiving the opening operation of the reprocessing opening/closing unit located above and sequentially closing the reprocessing opening/closing unit located below. This mode is controlled by That is, in the sequence mode 703, the reprocessing opening/closing unit is closed for a certain period of time so that the solids and discharged water respectively input to the reprocessing space units arranged in the vertical direction are sufficiently reprocessed, and then the opening operation is performed.

In addition, the solids transfer mode 704 receives the sedimentation amount detection value of the sedimentation amount detection sensor 830 and operates the solids suction pump 510 of the solids transfer unit 500 when it is higher than a preset sedimentation amount reference value, It is a mode in which text and voice notifying the transfer are output.

Here, the solids transport mode 704 is connected to the reprocessing storage unit 110 among a plurality of solids suction pumps when it is selected to transport the solids deposited according to the operation of the operation unit to the reprocessing storage unit 110 . When the storage transfer mode 705 for operating the solids suction pump and the transfer of the settled solids to the recycling bin 520 according to the operation of the operation unit are selected, among a plurality of solids suction pumps connected to the recycling bin 520 and a recycling transfer mode 706 for operating the solids suction pump.
