Generally, food waste is generated in homes and restaurants, and the discharge of such food waste is inevitable. The food garbage is usually stored immediately in a storage container or collected by a sieve filter installed in a drain port of a sink and stored in a storage container, and the food garbage filled in the storage container is discarded into a food garbage collection box.

When these food wastes are stored in a storage container, the food wastes contain a large amount of water, which causes spoilage even in a relatively short time, which causes the offending odor and harmful bacteria to propagate.

In order to solve such a problem, various types of food garbage disposers have been used. As an example, there is a processor for drying food waste by heat of a heater and converting it into general waste, which takes a lot of time and power to dry the food waste, and is not suitable for treating a large amount of food waste, . As another example, there is a food waste disposal system in which food waste is crushed and disassembled by using microorganisms. This is because a separate crusher is installed below a sink ball drain of a sink, and a separate microorganism The feeder is installed inside the sink. However, the installation of the feeder is complicated according to the size and structure of the sink, and the use thereof is inconvenient.

In order to solve such a problem, Korean Patent No. 10-1074349 entitled " Integrated food garbage disposer for disposing a fermented microorganism inoculation decomposition type sink "has a protruding molding part having an upper opening and a plurality of engaging projections on the outer circumferential surface, A crushing water receiving portion communicating with the engaging portion and having a trash receiving space; a crushing water receiving portion formed at a lower portion of the crushing portion and having an outlet communicating with the outside at one side; A driving motor having a shaft portion that is partitioned and mounted; a body made of a sound absorbing material that surrounds the interior; A microbial feeder formed on an outer circumferential surface of the body, the microbial feeder comprising a spraying hose connected to the inside of the waste accommodation space of the crushing unit, a supply hose supplied with the microorganism, and a control valve for regulating a supply amount of the microorganism; A microorganism reservoir to which the end of the supply hose of the microorganism feeder is connected to supply microorganisms to the microorganism feeder; A vertical penetrating attachment portion coupled to the upper engagement portion of the body by a coupling ring and for mounting the body to the drain hole of the sinkball; A cover plate covering the mounting portion and having a plurality of through holes, a packing being formed around the packing plate and being inserted into the mounting portion, And the shaft is connected to the lower end of the water bottle by a predetermined length, And a control unit for controlling the operation of the processor.
