DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fermentation drying method for fertilizing fertilizer by, for example, cutting grass, manure, garbage and the like.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG.
A stirring blade (3) mounted in the fermenter (2), a motor (4) for rotating the stirring blade (3), and a planar heating element fixed to the outer periphery of the fermenter (2) (5), an exhaust path (7) communicating with the fermenter (2) and interposed by a blower (6);
The fermenter (2) has a raw material inlet (2A, 2A) and a processed material outlet (2B, 2B). And a fermentation apparatus (1) provided with the above.

[0003] In the fermentation apparatus (1), the inlet (2A,
Raw material M such as cut grass, manure, garbage, etc. is put into fermenter (2) from 2A), fermentation bacteria are added, and the mixture is heated and stirred, and the raw material is aerobically fermented to produce fertilizer. In the above fermentation process, the gas in the fermenter (2) is exhausted from the exhaust path (7) by the blower (6), and the air is opened by opening the valve (8).
Replenished from (9). After the completion of the fermentation process, the obtained fertilizer is taken out of the fermenter (1), transferred to a dryer and dried.

[0004]

Since the fermentation apparatus (1) and the dryer are installed on the ground, there is a problem that if the capacity is large, the space must be secured accordingly.

[0005]

According to the present invention, as a means for solving the above-mentioned conventional problems, there is provided a fermenter in which a screw type agitator (13) rotatable in forward and reverse directions is mounted in a tank installed underground. (12) and a drying tank (19) installed underground adjacent to the feed direction of the stirrer (13) of the fermentation tank (12), and the fermentation tank (12) and the drying tank (19) In a fermentation drying apparatus (11) in which a partition (21) having a communication hole (21A) between
Charge the raw materials into the fermenter (12), and rotate the stirrer (13) forward and reverse
To ferment the raw material M, and then turn the stirrer (13) forward
And the fermented product is transferred to the drying tank (19) through the communication hole (21A).
The present invention provides a fermentation drying method for transferring and drying .

[0006]

The raw material M is put into the fermenter (12), and the screw-type stirrer (13) is rotated in a forward / reverse direction to ferment the raw material M.
When the fermentation process is completed and the raw material M becomes fertilizer, the fertilizer obtained by rotating the stirrer (13) forward is sent to the drying tank (19) through the communication hole (21A) of the partition (21). . The fertilizer is placed in a drying tank (1
It is dried in 9) and taken out on the ground.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to an embodiment shown in FIG. 1. In the fermentation drying apparatus (11) shown in the figure, (12) is a fermentation tank, which is installed underground and has a cover on the surface GL. An attachment port (12A, 12A) is provided, and the peripheral wall of the fermenter (12) is made of glass fiber reinforced plastic (FRP), concrete or the like. A screw type stirrer (13) is mounted in the fermenter (12) in the lateral direction, and the stirrer (13) is driven from a ground motor (14) by a pulley (14A), a belt (14B),
It is rotated via a pulley (14C) and the stirrer (13)
The rotary shaft (13A) is made hollow and hot air is sent from a hot air blower (15) on the ground.

A blower (16) is provided in the fermenter (12) from the ground.
An exhaust path (17) interposed communicates therewith, and a deodorizing tank (18) is further interposed in the exhaust path (17). A drying tank (19) is installed underground adjacent to the fermenter (12), and the drying tank (19)
Is made of FRP, concrete, etc., and an outlet (19A) with a lid is arranged on the surface of the ground GL.
A screw conveyor (20) is arranged immediately below A). The drying tank (19) is disposed in the feed direction of the stirrer (13) of the fermentation tank (12), and has a communication hole (21A) between the fermentation tank (12) and the drying tank (19). (21) is interposed.

[0009] In the above configuration, the charging port is provided in the fermenter (12).
(12A, 12A), feed the raw material M such as grass and garbage, further add fermentation bacteria, and rotate the stirrer (13) forward and reverse by the motor (14) to stir the raw material M and use the hot air blower (15 )
Then, hot air is sent through a rotating shaft (13A) of a stirrer (13) to heat the mixture to usually 60 ° C. or less. In the above fermentation process, the raw material M
Is moved forward and backward by the alternating rotation of the stirrer (13), and is stirred while not moving to the drying tank (19) side. The above fermentation process is usually 2
It is carried out for 4 to 72 hours, and the gas in the fermenter (12) is blower (1
It is taken out to the exhaust path (17) by 6), deodorized by the deodorization tank (18), and discharged. Activated carbon in the deodorization tank (18),
It is filled with water, chlorine dioxide water, etc.

[0010] The fertilizer above fermentation process is obtained after the completion of (outgoing
The fermentation product is rotated by the motor (14) to rotate the stirrer (13) forward, so that the drying tank passes through the communication hole (21A) of the partition (21).
Move to (19). In the drying tank (19), the fertilizer is naturally dried or dried by heating at a temperature of usually not more than 80 ° C. After drying, the opening (19A) is opened and the fertilizer is taken out to the ground by the screw conveyor (20).

[0011]

Therefore, in the fermentation drying apparatus of the present invention, both the fermentation tank and the drying tank can be installed underground, and it is not necessary to secure an installation space on the ground even for a large-capacity apparatus.
