The pulverizer is installed at the lower side of the sink to pulverize the food waste.

Here, the food waste introduced into the drain hole of the sink is pulverized to a small size by a pulverizing blade mounted on the pulverizer, and then discharged through a sewer pipe.

However, there is convenience when using the grinder configured as described above, but the following problems may occur in the prior art as described above.

In order to solve these problems, [Ministry of Environment] can cause problems due to clogging of sewage pipes due to food waste and overloading of capacity treatment at the sewage treatment plant when food waste (remnants) is processed in the sink using the conventional crusher for the sink. of October 22, 2012] to prohibit the use of crushers, except that food waste sludge treated in the crusher flows to the sewer within 20% of the wastewater and 80% is recovered or liquefied by microorganisms. However, it is said that it will be allowed only for rescue devices that are connected to the crusher in a unified way to prevent the user from dismantling the weight reduction device arbitrarily.
