The present invention relates to a food waste treatment device effective for eliminating odor pollution around a food waste treatment plant as a food waste treatment device by minimizing the volume, convenience of collection waste, and a perfect deodorizer.

Leftovers and residues left after cooking and cooking at homes, restaurants, and various workplaces, food waste is unsanitary due to bleeding of filth, dirty surroundings, and aggression of pests such as flies and mosquitoes.

These food wastes are ideal for landfilling, but nowadays, when the landfills have reached a serious level, they have become increasingly interested in incineration, fertilization and livestock feed.

However, incineration caused high energy costs and cancer-causing dioxin, odor fumes, and dust, which caused secondary environmental pollution problems. have.

In recent years, it has been proposed to reduce the volume of food waste by compressing the food waste and to discharge the sewage through the sewage pipe or through a separate purification process.

This method suggests various methods of drying compressed food wastes by incineration, disposal and organic fertilization.

As is well known, food waste is bulky, watery, decaying, and badly odorous.

In the case of a restaurant or a large kitchen where a lot of food waste occurs, the problem is more. The food waste can not be completely squeezed out, and the bulk of the food waste is inevitably squeezed out as it is, so there is a limit to the volume reduction and insufficient odor measures.

On the other hand, steamed food waste is steamed, and steam in the steaming process is forced out into the draft fan to be discharged to the drain hose, and the steam required for steaming is automatically supplied by the suction power of the draft fan, and after steaming, It is to dispose of steamed food wastes in garbage bags or collect them and use them as a comparison between livestock feed and organic matter.

However, this method has a high steaming energy cost and a long processing time, so it is practical to spend a lot of time on food waste disposal, and it is not only annoying and cumbersome, but also has to suffer odors until the garbage to be treated once is collected. I failed.

The present invention is to provide a food waste treatment apparatus by minimizing the volume by crushing and dehydrating food waste and hot air drying, and thus convenience of collection waste and perfect deodorization.

The present invention is finely crushed food waste that is added with the washing water to the hopper in the crusher and transported to the dehydrator, in the dehydrator to drain the water of the crushed waste sent to the dryer, in the dryer to quickly dry the dehydrated waste with hot air in the volume to minimize Sewage from the dry waste is reduced to feed and compost, and the sewage from the dehydration process is separated into a separate pipeline, and the odor generated from the drying process using hot air is mixed. Provided is a food waste disposal apparatus configured to remove odors by using a deodorizing device combined with air.
