Description

Food processor with prefab cutter

The present invention relates to a food processor including a prefab cutter, and more particularly, to a food processor having a spiral prefab cutter structure by disposing a space washer between a plurality of unit cutters.

In general, a certain amount of residue (waste food) is discharged from each home or restaurant every day, and the residue is used as a livestock feed or filtered through a simple strainer and then discarded. This residue treatment method increases the quantity of waste, and if the waste is not thrown away frequently, it causes odor and pollutes the surrounding air.

Recently, efforts have been made to reduce food waste in general households and restaurants, but it is difficult to control the amount of garbage that is gradually increasing, and when it is reclaimed, the place of landfill is limited, as well as the environment caused by odor and leachate. The damage was very serious.

Therefore, in recent years, the waste-based system has been implemented, and the government stipulates that a treatment device capable of inducing fermentation, drying, or extinction of food is required to be installed at the time of the construction of a cafeteria or apartment complex.

On the other hand, food waste generated at home or restaurant is separated and collected and placed in a collecting container for batch processing at a food processing plant or by installing a grinder in a sink drain to transfer, compress, grind, and dry the filtered food waste from the filtering network. This is done by reducing the throughput.

In general households or entertainment establishments, a device has been developed that is connected to the sink, that is, the sink's drain, so that food waste discarded through the drain can be processed by grinding and dehydrating. It is installed in the sewage pipe to the food waste flowing into the stream without filtering it to provide a device that can be separately collected and processed through the crushing and dehydration process.

On the other hand, a method of removing odor by mixing an odor remover, a fermentation mold, or the like in a grinder may be used. In addition, there may be a method of separating and discharging with the water as one of the separate collection method of food waste generated at home or restaurant.

While reducing the overall size of the food added in the process of crushing food waste, the conventional literature suggesting a method that can effectively treat the input food waste, see Publication No. 10-2011-0080601 (2011.07.13) Can be. In this document, an independent driven dual screw structure enables food waste to be circulated in the housing, and processes such as pressing, dehydrating, crushing and drying the food can be repeatedly performed in one housing. Start the food waste disposal device,
