PROBLEM TO BE SOLVED: To prevent the excessive accumulation of crushed fine particles in the bottom parts of a discharge chamber and a discharge chamber by forming drop openings through which treated substances can be dropped in the bottom part of the treatment chamber or the bottom parts of the treatment chamber and the discharge chamber. SOLUTION: Chutes 22, 23 through which treated substances accumulating in the treatment chamber A2 and discharge chamber A3 of a fermentation tank A can be dropped are formed in the bottom parts which are arc-shaped lower surface parts of the chambers A2, A3, and the chutes 22, 23 are positioned in the receiving area of a recovery tray 12. The chute 22 of the treatment chamber A2 is formed at a position corresponding to the lower side arc-shaped part of the tip rotation locus of an agitating claw 16b which is located in the treatment chamber A2 and rotates, and the opening lateral width of the chute is made to coincide approximately with the action width Z of the claw 16b. In this way, crushed fine articles are prevented from being deposited excessively in the bottom parts of the treatment chamber A2 and the discharge chamber A3.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fermenter for a garbage disposer for fermenting and decomposing organic substances such as garbage.

[0002]

2. Description of the Related Art A garbage disposal machine is known which composts organic matter such as garbage generated in ordinary households by utilizing decomposition by fermentation bacteria and uses the compost as a fertilizer for reduction. Generally, a stirring rotor for horizontally supporting garbage and fermentation bacteria put into a fermentation tank in the same tank is used.
To promote fermentation and decomposition of garbage and the like, and to take out compost from the tank.

[0003]

If the fermenter of the garbage disposer as described above is a single chamber, the garbage mixed with the fermented garbage is mixed in the entire room. The separation is not performed well, the processing efficiency is poor, and the product is not finished well. Therefore, the inside of the fermentation tank is partitioned into a plurality of chambers of an input chamber, a processing chamber, and a discharge chamber by a partition wall in a direction orthogonal to the axis of a stirring rotor supported in a horizontal direction in the fermentation tank. Are charged into the charging chamber, and those which have been agitated and pulverized in the charging chamber and decomposed by fermentation bacteria to a certain extent are allowed to flow out of the overflow portion of the partition wall into the processing chamber to further proceed with the fermentation processing. It is preferable that the processed material overflowing from the processing chamber to the discharge chamber is caused to flow out of the discharge port formed on the side wall of the discharge chamber and collected in a tray or the like. When partitioned into a plurality of chambers, those that have been agitated and pulverized by the stirring rotor and made into fine particles are difficult to move and stay in the lower bottom portion of the processing chamber or the discharge chamber, and the remaining matter is caused by the rotation of the stirring rotor. Excessive load is applied, and in extreme cases, stirring rotor
A situation arises in which is locked so that it cannot rotate.

According to the present invention, the inside of a fermentation tank is divided into a plurality of chambers by a partition plate so that garbage and fermented food can be separated well, while being stirred and pulverized into fine particles. This does not excessively stay at the bottom of the processing chamber or the discharge chamber, and does not apply a large rotational load to the stirring rotor.

[0005]

That is, according to the present invention, a stirring rotor provided with a plurality of stirring claws is horizontally laid horizontally in a fermentation tank and turned into the same tank. In the garbage disposer capable of performing fermentation decomposition while stirring the garbage thus produced and discharging the processed material outside the tank, the inside of the tank of the fermentation tank is moved with respect to the axis of the stirring rotor. Pulverization is performed by partitioning the charging chamber, the processing chamber, and the discharge chamber by a partition wall in a direction orthogonal to the processing chamber, and opening a dropout through which the processed material can drop out at the bottom of the processing chamber or the bottom of the processing chamber and the bottom of the discharge chamber. The fines are prevented from excessively accumulating on the bottom of the processing chamber or the discharge chamber.

Further, the inside of the fermentation tank is partitioned into a charging chamber, a processing chamber, and a discharge chamber by a partition wall, and the processed material can fall off to the bottoms of the processing chamber and the discharge chamber located on the lower side of the charging chamber. A simple structure for collecting fallen objects is provided by setting up a large number of falling ports and locating these falling ports together in the collection area of the collection tray.

In addition, a drop opening formed at the bottom of the processing chamber is provided so as to correspond to a lower circular arc portion of a tip turning trajectory of a rotating stirring claw located in the processing chamber. By making the width of the opening substantially equal to the working width of the stirring claw, it is possible to effectively remove the processed material from the falling port.

Further, a drop opening formed at the bottom of the processing chamber is formed by a plurality of holes scattered along the rotation direction of the stirring rotor, and is attached to the lower outer surface of the charging chamber. The sheet heater is extended to the lower outer surface side of the processing chamber while avoiding a drop opening formed at the bottom of the processing chamber.

The left and right partition walls (C2) and (C1) have substantially the same shape, and each partition wall has a dividing surface located at substantially the same height as the axis of the stirring rotor (B). The upper partition wall is divided into a lower partition wall and an upper partition wall. By removing the upper partition wall, the stirring rotor (B) can be easily attached and detached.

Each of the upper partition walls of the partition walls (C2) and (C1) has an overflow port (20) at a predetermined height.
