To form a drying path.

[0003]

A part of the steam generated in the tank is sucked and exhausted from the intake port by the drying path of the processing machine described above, but a large amount of steam adheres to the back surface of the lid and condenses. . At this time, the water droplets that have aggregated on the back surface of the lid grow and drop into the food waste in the processing tank, so that the drying efficiency of the food waste in the processing tank decreases.

An object of the present invention is to provide a food waste disposer having a high efficiency of drying food waste.

[0005]

According to the food waste processing machine of the present invention, a processing tank for storing and agitating food waste, a heater for heating the inside of the processing tank, and steam generated in the processing tank are included. There is provided a food waste disposer having an exhaust means for guiding air to the outside of the tank and a lid for covering the treatment tank, and the lid has an inclined surface for guiding condensed water droplets to the exhaust means on the back surface.

The garbage in the present invention includes not only garbage but also garbage having a relatively high water content generated in various facilities. The treatment tank in the present invention is a sealable container having a capacity capable of storing raw garbage, and the raw garbage stored in the tank is easily dried by a stirring means such as a stirring blade that is rotated by power. It is a processing tank in which the amount can be reduced by pulverizing, stirring, and drying. The heater in the present invention is a heat source that generates a quantity of heat capable of producing dehydrated and dried food waste that is stirred in a treatment tank to produce solidified compost, and may be an electric heater, a gas or petroleum heater. Or high frequency heating means.

The exhaust means in the present invention means an exhaust air blowing system for guiding the air containing the vapor generated in the processing tank from the inside of the processing tank to the drain tank arranged outside or inside the processing tank, and is at least electrically driven.

The lid in the present invention means one which can seal the inside of the processing tank and guide the vapor generated in the tank to the exhaust means.

The inclined surface in the present invention means that the adhesive force generated between the condensed water droplets on the back surface of the lid slightly exceeds gravity, and the water droplets fall along the surface without falling vertically to the lid. It means a surface with a slope that leads to the outer periphery of the body,
The surface is preferably composed of a uniform smooth surface. The inclined surface may be formed in a dome shape, or may be formed in a linear shape at a constant inclination angle. Further, it is preferable to set it on a surface having a predetermined wettability by resin coating or the like.

[0010]

In the food waste processing machine of the present invention, the food waste is stored in the processing tank, covered with the lid, and stirred and heated. The air containing the vapor generated in the treatment tank is guided to the outside of the tank by driving the exhaust means. Since the lid covers the processing tank, steam or odor generated from the processing tank does not leak out of the machine.

Here, the water droplets condensed on the back surface of the lid body are guided to the exhaust means through the inclined surface formed on the lid body.
Therefore, water drops are prevented from falling into the processing tank, and the food waste is efficiently dried. The raw garbage that has been dried for a predetermined period can be used as a compost.

As a result, water drops are prevented from falling into the processing tank 3, and the food waste is efficiently dried. Since the deodorizing platinum catalyst 21 and the preheater 22 are installed at the fan discharge port 7b, it is possible to prevent odor from leaking out of the machine.

6 to 8 below show an embodiment of a preferable method for treating food waste using a food waste treatment machine. Here, when the above-mentioned food waste disposer is used, the porous biodegradable polymer mass 31 is put into the processing tank 3 (FIG. 6), mixed with the food waste, and both are stirred simultaneously (FIGS. 7 and 7). 8).

The biodegradable polymer refers to a polymer material which is decomposed by contact with microorganisms and is finally converted into water and carbon dioxide gas. When it is buried in soil, it simply has a shape. Not only disintegrates, but refers to those that are completely assimilated and metabolized by microorganisms. Examples of biodegradable polymers include polypeptides, polysaccharides, nucleic acids, and aliphatic polyesters.

The polymer block 31 is formed by melt-spinning a biodegradable polymer into a spherical shape, and is formed into not only a spherical body but also a nodule having a predetermined shape, for example, a polyhedron, a columnar body, or a tubular body. Good. The polymer block 31 is preferably made of an aliphatic polyester. Examples of the aliphatic polyester include polycaprolactone, polyethylene succinate, and microbial polyester. Aliphatic polyester can be molded into a predetermined shape by melt spinning, does not decompose or deteriorate due to moisture in the air during storage and use, and is a natural environment with many microorganisms in soil or water. When placed in an environment, an enzyme-degradable polymer mass can be formed in which the microorganism begins to degrade only by the enzyme secreted outside the microbial cell.

The polymer block 31 is preferably porous and composed of spheres or polyhedra. What is this porosity?
It is a substance having pores on its surface for taking in moisture and / or odorous components inside, and the pores may be independent pores or continuous pores. When the polymer mass 31 is porous, the water content can be adjusted when it is buried in the soil, and the decomposition by microorganisms can be promoted. When the polymer mass 31 is a sphere or a polyhedron, the wet strength at the time of stirring is increased, and rapid disintegration in the presence of water can be prevented.

When treating garbage, biodegradable polymer block 3
1 is put in the processing tank of the food waste processing machine 1, mixed with the food waste, and both are stirred at the same time. At this time, the biodegradable polymer block 31 is stirred together with the food waste, and the food waste is crushed and uniformly disentangled, so that the drying efficiency is increased.

If the biodegradable polymer block 31 is made of an aliphatic polyester, it is a material having a relatively high wet strength and a hydrophobic property, so that it does not decompose or deteriorate due to moisture, etc. When placed in a natural environment in which a large number of microorganisms such as the above exist, an enzyme-degradable polymer mass that begins to decompose by an enzyme secreted outside the bacterial cells is obtained. Furthermore, biodegradable polymer mass 31
However, if it is porous and formed of spheres or polyhedra, it becomes easier to control the water content when it is buried in the soil, and it is possible to accelerate the decomposition by microorganisms, and the wet strength at the time of stirring increases, and the presence of water Can prevent rapid collapse in.

The food waste that has been dried for a predetermined period is buried in the soil as a compost in which the biodegradable polymer mass 31 is mixed and decomposed by microorganisms. The biodegradable polymer 31 is
The enzyme secreted outside the microbial cell starts to decompose it, and then it decomposes and is completely assimilated, metabolized, and finally converted into water and carbon dioxide. Since the polymer mass 31 is porous and has a spherical shape, when it is buried in soil, it becomes easy to control the water content and promote decomposition by microorganisms.
