Description

Food waste carbonization

The present invention relates to a carbonization treatment device for food waste, and more particularly, to improve the reduction rate of food waste by carbonizing the food waste to minimize the volume and to sterilize the harmful food generated at the same time as the food waste decay. The present invention relates to a carbonization processing apparatus for food waste which minimizes environmental pollution by efficiently removing steam and odor generated during garbage disposal.

In general, food wastes discharged from homes and restaurants contain a lot of water, so if you throw them in plastic bags as they are, they are bulky and weighty. Since landfills are made in landfills, there are no suitable landfill sites that can steadily increase the amount of garbage.In addition, there are severe odors in the state before the collection of garbage and landfills. There was a problem such as wasted.

Therefore, as a device designed to treat conventional food waste relatively simply, there were a dehydration device, a drying device, a fermentation device, a fermentation annihilation device, and an incineration device.

However, the dehydration device and the drying device have a disadvantage in that the weight loss effect is reduced by removing only the moisture of food waste, and the volume of the final by-product is increased. In addition, there is a disadvantage that the size of the treatment tank is larger than the food treatment capacity due to the large volume of moisture control material supplied, and there is a concern that harmful bacteria are generated according to the composition of the optimum environment in which the fermentation microorganism is most active.

In addition, the incinerator requires the installation of additional equipment such as a burner for incineration and pollution prevention device for environmental pollution, this device has a disadvantage that it is difficult to install in a narrow space, such as home or food.

The present invention has been made in view of these points, by carbonizing the food waste to improve the reduction rate of food waste by minimizing the volume of the final food waste, sterilization of harmful bacteria produced by the decay of food waste At the same time, it effectively removes the steam and odor generated during the food waste disposal process, freeing it from the environmental pollution caused by food waste.Carbonated powder is recycled as compost to use resources and provide a pleasant environment. Its purpose is to provide a treatment device.

Another object of the present invention is to provide a food waste carbonization apparatus that is simple in structure, easy to operate by a user, and can be used even in a narrow indoor space without any additional equipment or installation.

The object of the present invention as described above, by heating the carbonized cylinder by the indirect heating method by the heat generated in the heat transfer to maintain the temperature inside the cylinder at 100 ~ 350 ℃, by maintaining the temperature for 3 to 8 hours It is achieved by carbonizing the introduced food waste and pulverizing the carbonized food waste and then discharging it in a dry steam state in which suspended matter is removed.

That is, a carbonization processor for carbonizing powdered food waste by indirect heating, a primary filter for filtering fine dust, steam, and odor components introduced through the first pipe from the carbonization processor, and a second filter from the primary filter. Secondary filter that collects excess steam and odor components introduced through pipes and discharges them to the outside in dry steam state, and injects carbonized powder, steam and odor components generated from carbonization processor into primary filter and simultaneously It is characterized by consisting of the inlet means for forced discharge to the outside by introducing the steam and odor components generated from the secondary filter.
