Description

Food Disposer {FOOD WASTE DISPOSER}

The present invention relates to a food processor.

In general, as soil reclamation or marine dumping of food waste generated after cooking various kinds of food in the kitchen sink is prohibited, the government and each local government have implemented a volume-rate system to reduce the amount of food waste collected and collected food waste. Various methods are being tried, such as processing and making fertilizer or feed, or using it as an energy source.

A facility for processing food waste is considered to be economical to maintain only when the amount of treatment is at least several tens of tons. In the case of local governments with poor finances, they are unable to build large-scale food processing facilities.

In consideration of this reality, a method of disposing of food waste at home or at a restaurant by itself while reducing the amount of food waste generated at home or at a restaurant has been proposed. Accordingly, a food waste disposer that is attached to the lower part of the sink to crush food as a device for directly installing and disposing of a food waste disposal device under the sink of a home or restaurant, and a food waste disposer that uses microorganisms to process food Microbial treatment equipment and the like are used.

However, in the case of a product in which the food waste grinder and the microorganism processor are separated, the food waste grinder and the microorganism processor are connected through a connection pipe. For this reason, if the connection pipe is disconnected and directly connected to the sewer for use, the pulverized product is discharged directly into the sewer.

On the other hand, in order to reduce the decomposition time of microorganisms through the microbial processor, an effective pulverization technology for food waste is required.
