The present invention relates to a food waste processing apparatus for processing various food waste discharged from food factories, restaurants, and homes, and more specifically, to physically crush various food wastes introduced and biologically decompose by enzymes. It is to enable the feed and fertilization treatment of the molecular fine particles of the enzyme substrate complex is decomposed to moisture content of 3 ~ 6%.

Food waste discharged from food factories, restaurants, and homes is a situation in which most landfills are buried, or environmental pollution due to leachate from landfills and landfills is a serious social problem. The plan is being researched and developed.

As a representative method for recycling resources, food waste is recycled as compost through forced drying and fermentation using microorganisms. However, microorganisms use sawdust, rice husk, rice straw, and other swelling materials (膨化 材). It takes up a lot of space because it has to go through hassle, rot and sterilization process.

In recent years, a food waste processor having a compact size and improved processing capacity has been disclosed.In the case of such a food waste processor, a rotating shaft driven by a motor is installed inside a synthetic resin processing tank that can be stirred and fermented, and several stirrings are carried out on the rotating shaft. It is attached to the wing to allow the food waste introduced into the stirring tank to be fermented by stirring with the fermentation bacteria. In the case of the conventional food waste processor configured as described above, in the case of food waste having a high moisture content introduced into the treatment tank, In addition, since the stirring blade was formed in a straight shape, there was a problem such that the stirring of food waste in the treatment tank was not smoothly performed.

Accordingly, the present invention has been developed and researched to solve the problems of the conventional food waste processor as described above.

In order to solve the above technical problem, the present invention provides a differentiation function of the first tribology (tribology) theory. By frictional rotation (zero touch) with the inner wall of the tank and the finishing tank, the food waste (hereinafter referred to as "the object to be treated") without the blind spot is physically crushed by friction and abrasion mutual collision.

Second, the band heater is installed outside the digestion tank and the filament tank, and the aerobic redox hydrolysis mixed enzyme (liquid) is added to the object to be treated, and the enzyme is stirred while warming to the optimum temperature of 40 ~ 70 ℃. Due to the catalytic function of cleavage hydrolysis of water, moisture is evaporated and discharged at low temperature, while treated material with 30 to 90% water content is recycled material which is an enzymatic substrate complex in the form of molecular fine particles having 3 to 6% water content. I would have to.
