Next, the heating means 70 of this embodiment will be described in detail.
The heating means 70 includes a heater 71 that contacts the lower surface of the bottom plate 14 of the treatment tank 101 and a warm air feeding device 72 that feeds warm air into the treatment tank 101. In addition, the microbial decomposition treatment medium is maintained at a temperature suitable for microbial decomposition, and the water contained in the organic waste is evaporated, thereby preventing a decrease in the microbial decomposition processing capability due to excessive water.
The heater 71 works particularly effectively to maintain the organic waste and the microbial decomposition treatment medium at a temperature suitable for microbial decomposition.
Further, the hot air feeding device 72 is effective particularly for evaporating the water contained in the organic waste, and is suitable for processing livestock excreta having a large amount of water.
And these heater 71 and the said warm air inflow apparatus 72 can also operate any one or both according to the environment of the place where the said decomposition processing apparatus A is used, such as atmospheric temperature and humidity. .

A plurality of the heaters 71 are fixed to the lower surface of the bottom plate 14 in the processing tank 101, and the voltage is controlled so that the temperature in the processing tank 101 falls within a temperature range (60 to 80 degrees) suitable for microbial decomposition.
The hot air feeding device 72 includes a hot air generating source 72a placed on the upper surface of the upper plate 101A of the processing tank 101, and a discharge section 72b detachably connected to the hot air generating source 72a.

The discharge section 72b is a long discharge pipe 72b1 that is horizontally installed and fixed in parallel to the rotation shaft 20 in the processing tank 101.
The discharge pipe 72b1 has a distal end surface closed and a plurality of discharge holes 72c arranged in the longitudinal direction and arranged in two rows in the circumferential direction.
And these discharge holes 72c are arrange | positioned so that a warm air may be sprayed uniformly to the organic waste in the processing tank 101 and the microbial decomposition processing medium.
Further, the discharge pipe 72b1 is configured so that the total opening area of all the discharge holes 72c is equal to the flow area (discharge) of the discharge pipe 72b1 in order to equalize the flow rate of the warm air ejected from each of the plurality of discharge holes 72c. The area calculated from the inner diameter of the pipe 72b1 is ½.
That is, when the sum of the opening areas of all the discharge holes 72c is larger than one half of the distribution area of the discharge pipe 72b1, the distribution resistance in the pipe causes the tip of the discharge pipe 72b1 (the right end in FIG. 1) to When the ejection hole 72c is smaller than one-half of the flow area of the discharge pipe 72b1, a sufficient ejection amount cannot be secured at each of the discharge holes 72c.

Further, the decomposition processing apparatus A of the present embodiment is provided with a control circuit (not shown). The control circuit controls the driving unit 113 so that the stirring unit 1 repeats the stirring operation and the stop, and the heating means. 70 is operated at least during the stirring operation of the stirring unit 103, and is controlled to be stopped for all or part of the time during which the stirring unit 103 is stopped.
The drive unit 113 is controlled so that the stirring unit 103 repeats forward rotation and reverse rotation with a stop time interposed therebetween.

The control circuit will be described in detail. Contact means (not shown) that is turned on each time the disassembly processing apparatus A is used is provided, and a timer means is provided in a control panel (not shown).
The timer means is a control circuit constituted by a relay circuit, a sequencer or the like, and starts counting a set time every time the contact means is turned ON, and during the counting, heating in the decomposition processing apparatus A When the energization of the means 70 is continued and the contact means is not turned ON within the set time, the energization to the heating means 70 is cut off after the set time elapses.
Specifically, when the contact means is turned on, the rotation shaft 20 in the decomposition processing apparatus A is rotated by the drive unit 113 for a predetermined time, and at the same time, counting of the timer means and energization to the heating means 70 are started. Is done.
If the contact means is turned on again during the counting, the timer means starts counting again from zero seconds and the energization of the heating means 70 is continued.
If the contact means is never turned ON during the counting, the energization to the heating means 70 is cut off after a set time has elapsed.
When the contact means is turned on after the set time has elapsed, the timer means starts counting again from zero seconds, and the energization of the heating means 70 is resumed. The operation is repeated.

According to the decomposition processing apparatus A having the above configuration, as shown in the figure, the organic waste and the microbial decomposition processing medium in the processing tank 101 conflict with each other inside and outside in the radial direction by the outer conveyance blade 30 and the inner conveyance blade 40. In addition to being conveyed in the direction, it is conveyed and circulated in opposite directions on both sides of the substantially central portion of the rotating shaft 20 as a boundary.
At that time, the organic waste and the microbial decomposition treatment medium are circumferentially arranged so as not to adhere to the inner surface of the processing tank 101 by the circumferential stirring unit 50 between the end of the outer conveying blade 30 and the inner surface of the processing tank 101. Therefore, it is smoothly conveyed inward and outward in the radial direction.
Moreover, since the support with respect to the spiral belt | band | zone body 31 is the both-ends support which supports in a sandwiching form from the thickness direction both sides of the spiral belt | band | zone body 31, the support strength improves greatly compared with a cantilever support.
That is, since the support strength can be improved without using means for increasing the thickness of the spiral band 31 and the support rod 32, an increase in cost can be suppressed.
Therefore, microbial decomposition treatment can be performed with high efficiency, cost increase can be suppressed, and high resistance against the movement resistance of organic waste can be provided.
The transport direction of the organic waste and the microbial decomposition treatment medium is changed to the direction opposite to the arrow shown in FIG. 4 when the driving unit 113 is reversely controlled at regular intervals.
Furthermore, since the heating means 70 is controlled by the timer means, it is possible to prevent the degradation of the microbial decomposition efficiency due to excessive drying in the treatment tank 101 and to prevent a fire.
Then, as shown in the drawings and the drawing (the input portion on the right side of the drawing), during the manure decomposition process, the shooter 106 is housed in the opening 104, and the opening is closed by the outer lid 105 that closes the opening 104. Hidden with 104.
In addition, when dropping manure, as shown in the drawings and the drawing (the left side of the drawing), the outer lid 105 is opened, and the shooter 106 inclined upward in the loading direction side Appears immediately above the upper surface 101A of the processing layer 101 located on the input side.
That is, the front-rear width for receiving manure poured from above is the width obtained by adding the front-rear width of the shooter 106 to the front-rear width of the opening 104 in a plan view, which is substantially the same as increasing the front-rear width of the opening 104. Become.
Therefore, at the time of decomposition processing of manure, the shooter 106 is housed in the opening 104, and the shooter 106 that is soiled with manure is not exposed. Freezing of manure is prevented by the heat of the generated water vapor.
And when manure is thrown in, the manure can be reliably put into the processing tank 101 without expanding the front-rear width of the opening 104.
Therefore, it is possible to suppress the enlargement of the size of the opening 104 to the minimum or to maintain the surrounding environment satisfactorily and reduce the cleaning work without increasing the size.
