SUMMARY OF THE INVENTION The present invention provides an outer container and a fermenter that is rotatably supported in the outer container by using a breathable nonwoven fabric or a breathable heat insulating material without using a heater or a fan. In addition to imparting heat retention and moderate air permeability to the inner container, which prevents wasteful escape of fermentation heat generated during microbial decomposition in the inner container, the air (oxygen) necessary for aerobic decomposition and This problem has been solved by allowing the carbon dioxide gas and water vapor generated during the decomposition of garbage to naturally pass to the outside.

That is, according to the method for treating garbage of the present invention, an outer container is formed by attaching an air-permeable heat insulating material to the inner surface of an outer container body having a large number of through holes and the opening / closing lid body. The inner container body having a large number of through holes in the container and the opening / closing lid body are manually rotatably supported by the handle operation from the outside of the outer container, and the inner opening / closing lid body and the inner container body are A garbage surrounded by a breathable nonwoven fabric is formed by bonding a breathable heat insulating material to the outer side surface, further arranging a breathable nonwoven fabric on the inner surface of the inner container body and the opening / closing lid body, and forming an inner container. A processing space is formed, and the air required for aerobic decomposition of the garbage and carbon dioxide gas and water vapor generated by the decomposition of the garbage are removed from the garbage processing space while maintaining the inside of the garbage processing space with the air-permeable heat insulating material or the permeable nonwoven fabric. To In which is characterized by natural passed to process raw garbage.

Further, the garbage disposal apparatus of the present invention comprises an outer container provided with an opening / closing lid on the upper surface, an inner container rotatably accommodated in the outer container and provided with an opening / closing lid on a part of the peripheral surface, and A handle for manually rotating the inner container from the outside of the outer container is provided.The main body of the outer container and its opening / closing lid main body are provided with a number of through-holes, and a breathable heat insulating material is attached to the inner surface thereof. The main body of the inner container and the body of the opening / closing lid are provided with a large number of through-holes, and a breathable heat insulating material is attached to the outer surface of the inner container body and the inner and outer surfaces of the opening / closing lid body.

In order to impart air permeability to the processing apparatus, a large number of holes are provided in the outer container body, its opening / closing lid body, the inner container body and its opening / closing lid body constituting the processing apparatus.
The shape and size of the through-hole are not particularly limited. For example, when the through-hole is circular, the diameter is 5 to 10 mm,
In the case of a square, one side is about 5 to 10 mm, and a hole having an opening area of 20 to 100 mm ² by one through hole is formed at regular intervals, and an opening area ratio of a large number of through holes is 20 to 40
% . If the individual through-holes are enlarged to make the opening area ratio larger than 40%, not only does the strength of the device itself decrease, but also the heat retention and air permeability become unbalanced. Also, if the through hole is small, the air resistance will increase,
When the opening area ratio is set to 20% or less, the flow of the air is not smooth.

As the air-permeable heat insulating material to be attached to the inner surface side of the outer container body and the outer surface of the inner container body, a heavy woven fabric such as a breathable nonwoven fabric or a blanket, or an open-cell sponge sheet can be used.

In the case of a non-woven fabric having a ventilation rate of 15 cc / cm ² or less which is larger than m ² , sufficient heat insulation can be obtained, but the flow of air between the processing tank and the outside is reduced, and air supply and processing into the processing tank are performed. Discharge of carbon dioxide gas and water vapor from the tank is not smooth, and it is difficult to achieve a desired aerobic decomposition. Also, in order to improve the natural passage of water vapor and carbon dioxide from the garbage disposal space to the outside due to the rise in temperature when the garbage is decomposed by microorganisms, the inside of the outer opening / closing lid body and the outer The basis weight of the nonwoven fabric to be stuck on the side is 2
00-400 g / m ² , air permeability 70-90 cc / cm

The breathable nonwoven fabric forming the garbage disposal space of the inner container of the treatment apparatus has a basis weight of 400 to 600 g / m ² and a ventilation rate of 15 to 30 cc in consideration of abrasion resistance.
Needle-punched nonwoven fabric having a thickness of 1.5 to 2.0 mm / cm ² / sec. This garbage disposal space may be formed by laminating the needle-punched non-woven fabric on the inner surface of the inner container body and the opening / closing lid body, or the needle-punched non-woven fabric may be formed in a bag of the same size as the inner shape of the inner container body. Alternatively, after the bag is placed in the inner container body, the opening of the bag may be detachably attached to the opening of the inner container with a clip or the like. In addition, the garbage disposal space in the inner container is made of a breathable non-woven fabric bonded to the inner surface of the opening / closing lid body of the inner container, and a vent that can be inserted and removed from the opening / closing lid and can be attached along the inner surface of the inner container. When formed by a non-woven fabric bag, a non-woven fabric with a smaller basis weight than the above-mentioned non-woven fabric and a slightly larger air permeability is attached to the inner surface side of the inner container body, and the attachable breathable non-woven bag is made flexible to increase the strength.
