In recent years, the discharge of household waste has increased due to the improvement of living standards, and the disposal of such waste has become a big social problem.

In particular, the food waste left in each home or restaurant contains a lot of moisture, so the decay proceeds quickly, and not only a bad odor, but also very difficult to transport and handle.

When such food waste is buried in a landfill, water contained therein is leached to pollute the surrounding soil and rivers, and when decayed, methane gas is generated to cause problems such as fire and explosion.

Therefore, in recent years, various methods have been disclosed for removing water from food waste to reduce the volume and to recycle it as a raw material for livestock feed and fertilizer.

There are three types of food waste treatment: incineration, fermentation and drying.

Incineration is a method in which food is directly heated and incinerated, which has a high treatment cost due to water content and is not widely distributed by secondary pollutants due to smoke and odor generated during incineration.

Fermentation is a way to reduce the volume of food waste by the fermentation of food waste by microorganisms. However, the fermentation formula requires a fermentation time, and thus requires a treatment period of more than one day, and the processing speed varies depending on the components of food waste, the type of microorganism, the temperature and humidity of the reaction tank, and there is a problem such that severe odor is generated during the reaction. .
