A method and an apparatus have been developed as disclosed in JP-A-8-57458 and JP-A-8-57458.

[0004] Here, garbage is generally decomposed by a microorganism (aerobic bacterium "Bacillus") (aerobic decomposition treatment).
To do so, it is necessary to have an optimal location, temperature, oxygen content and moisture content for microorganisms. The cedar chips (hereinafter referred to as carriers) developed by the present inventor are the most effective as a material that effectively secures the four conditions (optimum housing, temperature, oxygen content and moisture content) necessary for this microorganism. is there. This one carrier is constituted by countless honeycomb-shaped vessels (cavities). The vein is a passage for transferring water absorbed by the plant from the roots to the leaves of the tree, and is most suitable for a place where microorganisms live, and has excellent water retention and breathability, which are important for the growth of microorganisms.

[0005] The same person as the present inventor has previously developed a garbage processing machine that effectively treats garbage using this carrier.

The garbage and the carrier brought to the center are dropped forward.

[0007] The garbage thus introduced is stirred in a garbage disposer for a predetermined time, so that aerobic microorganisms (hereinafter referred to as "cells") inhabiting the carrier favor carbon dioxide and water. It is subjected to temperative decomposition.

[0008]

However, there are various kinds of garbage, especially when the fats and the like of fish are thrown in as garbage, while the fats and the like are added to the carrier while being stirred in the garbage processing machine. And it becomes a dumpling-like mass. This lump was not crushed by the garbage disposer having the above-mentioned structure, but was only turned around the center of the garbage disposer.

At this time, the carrier in the mass blocks the vessel by fat or the like, so that fresh air or water is not supplied to the cells living in the vessel, and the cells are killed. Had been lost. As a result, the anaerobic microorganisms propagate and perform anaerobic decomposition treatment of the garbage, which makes it impossible to effectively aerobicly decompose all of the input garbage, and generates odors due to the anaerobic decomposition treatment. Problem.

[0010] The present invention has been developed in view of the above-mentioned points, and an object of the present invention is to be able to break crushed input garbage even if the garbage solidifies together with the carrier during stirring. Another object of the present invention is to provide a garbage disposer capable of efficiently performing aerobic decomposition treatment of all kinds of garbage and preventing the generation of odor.

[0011]

The garbage disposer 1 having the above configuration
In this case, first, a carrier is put into the stirring tank 3, and garbage is put into the stirring tank 3 through the opening 11 therein. The lid 12 of the opening 11 is controlled so that the rotation of the stirring blade 4 is stopped by opening the lid 12 when the garbage is charged, and the stirring blade 4 is rotated when the lid 12 is closed.

After the garbage is introduced as described above, the heater (not shown) is automatically operated, and the temperature is raised to 40 ° C. at which the activity of the cells attached to the vessel of the carrier becomes active. It is like that. When the temperature in the stirring tank 3 reaches 40 ° C., the operation of the heater (not shown) is automatically stopped. By raising the temperature of the stirring tank 3 to 40 ° C., the activity temperature of the cells is artificially created in a short time. The temperature increase of 40 ° C. or more is left to the activation temperature of the cells.

In this way, the garbage is stirred by the stirring blades 4 together with the carrier in which the cells live, whereby the input garbage is decomposed into water and carbon dioxide by the cells with the lapse of time, and the water is removed from the cells. The carbon dioxide gas is released into the atmosphere by the exhaust fan 32.

The stirring blade 4 having the above-described structure has a structure in which the carrier is softly stirred, and can supply oxygen required by the cells to all the carriers in the stirring tank 3. In other words, the stirring blades 4 are rotated by the driving means 5 so that the carrier filled in the stirring tank 3 is moved from both left and right sides of the stirring tank 3 to the near side of the center (front side 3 b side) and the lower part of the stirring tank 3.

It falls naturally from above the near side (front side 3b side) of the center of the stirring tank 3 downward. Therefore, the respective carriers are not stirred as kneaded, but are stirred with the soft feeling as described above without being damaged. Further, the amount of oxygen required by the cells can be uniformly supplied to all the carriers. Therefore, the activity of the anaerobic microorganisms can be suppressed, and the generation of offensive odor can be suppressed.

Further, when the garbage is fish fat or the like, the garbage is agitated with the carrier to form a dumpling mass. However, since the stirring tank 3 is provided with the protruding portion 41, the mass moved to the center of the stirring tank 3 by the stirring blades 4 is moved from the upper side to the lower side of the stirring tank 3 (the front side 3 b side). When it falls naturally, it hits the protruding portion 41 (short and small in FIG. 6) and is crushed by combing at the ridge 41a. Therefore, even if garbage such as fat is introduced, the mixing tank 3
It is possible to prevent anaerobic decomposition due to agglomeration inside.

FIGS. 7 and 8 show another example of the garbage processing machine 1. In this garbage processing machine 1, a projection 41 (see FIGS. 7 and 8) is different from that of the above-described example. The other configuration is the same as in the above-described example, and the description is omitted.

The projecting portion 41 of the garbage disposer 1 is generally rhombic or crescent-shaped as shown in the figure, and has a ridgeline portion 41.
a (top) is located between the tip portions 21 a and 22 a of the stirring blades 21 and 22 of the stirring blade 4. This projection 41
In the same manner as in the above example, a lump formed by stirring the carrier and the fat and the like of the fish can be crushed by combing at the ridge 41a (top). The design of the projecting portion 41 may be changed so as to be provided on the rear surface of the stirring tank 3.

The garbage processing machine according to the present invention can also be used as a processing machine for sewage sludge, swamp lake sludge, animal and plant food residue, and the like.
