【Example】

 Embodiments shown in the drawings will be described below. First, the entire conventional food waste processing machine will be described with reference to FIGS. The fermentor 2 is constructed by blow molding of synthetic resin, etc., and has an inlet 2a covered with the lid 3 at the upper end and a water outlet 2e also serving as a vent at the lower end. A lower net 4 is inserted inside the fermentation tank 2 at the water outlet 2e. Further, on the left and right side surfaces of the upper part, an upper opening 2d is opened at a portion provided with a recess, and a mesh plate 5 is attached to the upper opening 2d. Further, bearing support openings 2b and 2c for penetrating the support shaft 6 and for fixing the bearing support portion of the support shaft 6 are formed in the central portions of the left and right side surfaces of the fermentation tank 2.

A stirring device 7 is fixed to the support shaft 6, and the support shaft 6 does not rotate when the fermentation tank 2 is rotated by the rotating handle 8. Therefore, the stirring device 7 also rotates the fermentation tank 2. It doesn't rotate. When the food waste is rotated by the rotation of the fermentation tank 2 by the rotating handle 8, the food waste is caught by the agitator 7 and agitated. A plurality of aeration pipes 1, 1, 1 are arranged below the stirring device 7 provided on the supporting shaft 6 and at a position where the contents are easily mixed and stirred when the fermentation tank 2 is rotated. .

Next, when the lid 3 is closed, a lid bottom ventilation hole 3b is opened at the bottom of the portion fitted into the input port 2a of the fermentation tank 2, and this is the upper net 9 Is covered by. The inside of the lid 3 is configured like a double container, the inside of the lid 3 communicates with the inside of the fermentation tank 2, and the inside of the fermentation tank 2 also has an air inside the lid bottom vent hole 3b. It is possible to pass through the inside of the lid body 3 via the and to go out to the atmosphere from the lid opening portion 3a. The lid body 3 is pivotally supported by a lid body pivot portion 2f of the fermentation tank 2 and pivoted to an open state and a closed state with the lid body pivot portion 2f serving as a fulcrum. The fixing member 11 attached to the fermentation tank 2 is locked and fixed.

Further, the fermentation tank 2 is made of a semi-transparent synthetic resin, and the amount of food waste can be judged from the outside. If the amount of food waste is excessive, the fermentation will not be promoted. Therefore, as shown in FIG. 2h is engraved. Next, the upper end of the rotary handle 8 is fixed to the sprocket shaft 12, and the chain 14 is wound around the sprocket 13 fixed to the sprocket shaft 12, and the chain 14 also supports the support shaft. It is wound around the sprocket 15 that also serves as the support boss of 6. Therefore, when the fixed sprocket 15 is rotated by the rotary handle 8 via the sprocket 13 and the chain 14, the fermentation tank 2 is decelerated and rotated around the support shaft 6 with a light force. Reference numeral 16 denotes a support stand attached to the shaft support 17.

According to the above conventional method, the fermentation of the fermentation tank 2 is performed by the stirring device 7 fixed to the supporting shaft 6 supporting the fermentation tank 2, and the garbage is circulated. Since it is not agitated, the whole does not have a uniform water content, and aerobic fermentation is not uniformly performed, so good fermentation cannot be performed. The present invention is an improvement of the above points.

In FIG. 1, a processing machine 18 is an outer fermentation tank, and an inner fermentation tank 19 is arranged in the outer fermentation tank to form two fermentation tanks inside and outside. A spiral blade 20 is provided on the outer wall of the inner fermentation tank 19, and an air supply cylinder 21 covered with a non-woven fabric or the like is erected at the center of a bottom opening 22 of the inner fermentation tank 19. A downward facing plate body 23 is fixed to a bottom opening 22 of the inner fermentation tank 19, and a hollow box 24 is attached to the center of the plate body 23. The bottom opening 22 of the inner fermentation tank 19 and the downward-facing dish 23 are fixed by, for example, a connection rod (not shown) in the radiation direction between the downward-facing plate body 23 and the inner fermentation tank 19. As shown in FIG. 4, the dish 23 has a vent hole 25 connected to the air supply cylinder 21, and the box 24 has a vent hole 26 on the peripheral wall thereof. The protrusion 27a of the protrusion 27 provided on the bottom wall of the box 24 is fitted into the groove 29a of the receiver 29 attached to the shaft of the motor 28, and the inner fermentation is performed by the motor 28 via the downward facing plate 23. While the tank 19 is rotated, the inner fermentation tank 19 can be attached to and detached from the motor shaft. The flap 23a of the dish 23 is adapted to overlap with the pot-shaped guide 18b of the bottom wall 18a of the outer fermentation tank 18.

At the center of the empty space 30 between the bottom wall 18a and the outer wall 18c of the outer fermentation tank 18, there is an outer wall 31a of the blower chamber 31 connected to the pot-shaped guide 18b. A blower fan 33 rotated by a motor 32 is provided in the blower chamber 31, and a vent hole 34 is provided in the outer wall 31a. To the right of the vacant room 30 is an air vent 35. A lid 36 having a double structure is pivotally supported 37 above the outer fermentation tank 18 and can be opened and closed. A sensor 38 is provided at the tip of the lid 36 so as to stop the rotation of the inner fermentation tank 19 when the lid is opened. The outer lid 36a of the lid 36 has a control box for operating the motor. A net 40 with a deodorant is stretched on the inner lid 36b of the lid 36. An exhaust chamber 41 is provided on the side of the pivot 37 of the lid 36, an exhaust fan 43 driven by a motor 42 is provided inside, a ventilation net 44 is provided on the inner wall of the exhaust chamber 41, and an opening 45 is provided on the outer wall. There is. Others 46 are tires provided at the bottom of the outer fermentation tank 18, and 47 is a stand.

Now, the lid 36 is opened with the pivot 37 as the center, and the garbage is put into the inner fermentation tank 19. When the lid 36 is closed after insertion, it is detected that the sensor 38 is closed.Therefore, when the switch of the control box 39 is pressed, the motors 28, 32 and 42 are driven and the inner fermentation tank 19 is rotated. At the same time, the blower / motor cooling fan 33 and the exhaust fan 43 rotate. Therefore, the garbage put in the inner fermentation tank 19 is circulated and stirred by the spiral blade 20 from the inner fermentation tank 19 to the outer fermentation tank 18 and from the outer fermentation tank 18 to the inner fermentation tank 19. On the other hand, air is sucked in from the air port 35 by the air blower / motor cooling fan 33, passes through the vent hole 26 of the box 24, is sent to the air supply tube 21 through the vent hole 25 of the pan 23, and the inner lid 36b is closed. It is discharged from the deodorant-equipped net 40 to the outside by the exhaust fan 43. The deodorized moist air is discharged from the exhaust opening 45.

According to the present invention, the rotation of the inner fermentation tank 19 circulates and stirs the food waste with the spiral blade 20, so that the water content becomes uniform throughout, and the motor 28 is blown and the motor cooling fan 33 is used to control the motor 28. The passed air is heated by the heat of the motor and sent into the fermentation tank, so that aerobic fermentation is uniformly performed. Further, the air passing through the fermentation tank is deodorized by the deodorant-equipped net 40, so that the odor is not released to the outside. While the lid is open, the inner fermenter 19 does not rotate because it sends a signal to the control box 39 that the sensor 38 is open. Therefore, it is dangerous. Further, the inner fermenter 19 can be taken out of the outer fermentor 18 with the garbage contained in the shaft of the motor 28, and the fermented product can be discharged. Since the air supply cylinder 21 is stretched with a non-woven fabric or the like, clogging is prevented. The structure for constructing the fermentation tank of the present invention into two tanks inside and outside is not limited to the one shown in the drawings.
