The air supply port 61 and the exhaust port 37 are positioned higher than the axis of the fermentation drying drum 2 and are arranged in front of the vertical plane 62 extending vertically upward from the axis in the rotational direction. In the embodiment, the air supply port 61 has the vertical surface 62.
And extending from the axis of the fermentation and drying drum 2 and the vertical plane 6

The dolly 11 is open to the upper side and the right side, is arranged below the main body frame 13 of the gantry 1, and is located below the fermentation and drying drum 2.

Next, the operation of the fermentation / drying apparatus configured as described above will be described. As the organic matter to be fermented and dried, for example, head, boned fish ara or leftover rice etc. are used,
Their water content is about 65 to 75%. Dried okara or sawdust having a water content of about 10% is added as a water content adjusting agent to such an organic material to adjust the water content to a range of 40 to 60% to form a treated product. The soil bacteria to be used together have a suitable activity range of 60 to 75 ° C and a moisture content of about 50%. For example, commercially available MU bacteria (8961 Iriyamabe, Nagano Prefecture Matsumoto City, Uchijo Agricultural Research Institute) Manufactured) is preferable.

When the treatment is carried out by a fermentation dryer,
First, the fermentation drying drum 2 is stopped with the opening 24 on the upper side, and the attachment / detachment lid 17 is removed, so that the treated matter and the soil fungus are adjusted to a weight ratio of 1: 1/1.
It is blended at a ratio of 0000 and put into the fermentation drying drum 2 through the opening 24. In this case, the air supply port 6
1 and the exhaust port 37 are positioned higher than the shaft center which is the rotation center of the fermentation drying drum 2, the fermentation drying drum 2
The processed product can be charged into the vicinity of the axial center position where good stirring and mixing can be performed, and the work efficiency can be improved. Next, both gear motors 6 and 46 are driven to rotationally drive the fermentation drying drum 2 and the drive shaft 44 of the crushing device 7, and hot air is supplied from the burner 9 into the fermentation drying drum 2.

As a result, the treated material and soil fungi put into the fermentation and drying drum 2 are stirred by the rotation of the fermentation and drying drum 2 while being rotated with the inner surface of the fermentation and drying drum 2 and being totally inverted. While being mixed, the crushing device 7
The crushing claw 45 of crushes the lump of the processed material and soil fungus in the fermentation and drying drum 2 and stirs and mixes them. Further, the temperature in the fermentation and drying drum 2 rapidly rises due to the hot air of 250 to 350 ° C. supplied from the burner 9, whereby the upper layer portion in the drum 2 reaches 300 to 350 ° C. As a result, the temperature of the treated product is heated to about 60 ° C. in about 20 minutes after the start of operation, and the moisture content of the treated product is reduced by 2 to 3% from the time of the addition.

By the way, the fermentation and drying drum 2 as described above is used.
By the rotation drive of No. 1 and the supply of hot air from the burner 9 into the fermentation drying drum 2, the fermentation process proceeds, the processed product is continuously heated by further receiving hot air, and the fermentation process speed increases. .. After about 30 minutes have passed in this state, the temperature of the processed product becomes about 75 ° C., and the moisture content is lowered by 5 to 7% from the time of the introduction, and the processed product is in a semi-ripe state. The semi-ripened intermediate processed product is further dried by hot air from the burner 9. When this drying treatment is performed for about 30 minutes, the temperature of the treated product rises to about 85 ° C and the water content is 10%.
It decreases to below, and it becomes a blackish brown, finely powdered finished product, that is, a fertilizer or feed that has been converted to corrosive soil.

As described above, the treated product consisting of the organic waste or the like is fermented and dried in the fermentation and drying drum 2 by the action of the soil bacteria and the hot air to accelerate the fermentation and drying. It is used as a finely processed finished product, that is, as a fertilizer or feed that has been converted to corrosive soil. That is, by supplying high-temperature hot air into the fermentation drying drum 2, it is possible to heat the soil bacteria to the optimum activity temperature range in an extremely short period of time and to perform high-temperature treatment of the treated matter including organic waste. The processing time can be remarkably shortened, and further, the drying process can be performed continuously with the fermentation process with one fermentation drying drum 2, and the structure is simple. Then, when dried as described above, the supply of hot air into the fermentation drying drum 2 by the burner 9 is stopped,
The temperature in the fermentation and drying drum 2 decreases, and the dried processed product is allowed to cool.

As described above, during the processing of the organic waste, the entire fermentation and drying drum 2 is rotationally driven, so that the processed products and soil fungi put in the fermentation and drying drum 2 rotate in the fermentation and drying drum 2. As a result, the inner surface of the fermentation and drying drum 2 is rotated, and while being totally inverted, the mixture is stirred and mixed, and the temperature of the entire fermentation and drying drum 2 becomes high, and the inner surface of the fermentation and drying drum 2 and the processed product are rotated together. Therefore, the processed product is dried well. In the fermentation and drying tank,
When compared with an example in which a screw for stirring and rotating is provided, in the above example, unlike the invention of the present application, while stirring and mixing is partially retained, the processed product is
Unlike the invention of the present application, since it does not follow the inner surface of the fermentation and drying drum 2 that has reached a high temperature, the processed product cannot be dried as well as the invention of the present application.

Further, in the present invention, the crushing device 7 is further driven to rotate, and the crushing claw 45 crushes the mass of the processed material and soil fungus in the fermentation drying drum 2, so that the fermentation drying drum 2 is crushed. Even when a large processed product is charged, the processed product can be easily crushed, and in the process of drying the processed product,
On the surface of the processed product in the fermentation and drying drum 2, a processed product called lump and a lump of soil bacteria are easily formed, and this lump can be easily crushed by the crushing claw 45. Further, even when the processed material is caught between the crushing claw 45 and the inner surface of the fermentation / drying drum 2 during the crushing, the drive shaft 44 of the crushing device 7 is displaced from the axis of the fermentation / drying drum 2, and the fermentation / drying is performed. Since the rotation direction A of the drum 2 and the rotation direction B of the crushing device 7 are the same, the above-mentioned bite state is easily released.

Further, since the crushing claw 45 also cooperates with the rotation of the fermentation and drying drum 2 to stir and mix the treated material and soil bacteria in the fermentation and drying drum 2, the treated material and soil bacteria in the fermentation and drying drum 2 are agitated and mixed. Can be mixed with stirring even better. In particular, at the time of processing, the fermented and dried drum 2 is rotated so that the treated material and soil fungus are pushed in the rotational direction A of the fermented and dried drum 2 with respect to the circumferential direction, and as shown by the phantom line in FIG. Although the position is shifted to A, in the embodiment, the axis of the drive shaft 44 extends from the vertical plane 48 and the axis of the fermentation and drying drum 2 and is 90 degrees from the vertical plane 48 of the fermentation and drying drum 2. The crushing claw 45 is located at the center position or the substantially center position in the circumferential direction with respect to the horizontal plane 49 located forward in the rotation direction.
Most of the rotating area 67 of the above overlaps with the existing area 68 of the processed material and soil fungus in the fermentation and drying drum 2, so that the crushing and stirring and mixing by the crushing claw 45 can be performed more effectively.

Further, in the above case, since both ends in the axial direction of the fermentation and drying drum 2 are tapered parts 20 and 21 which are tapered toward the central part in the axial direction, the above-mentioned tapered parts 20 and 21 are formed. The processed product will be sent to the central portion side in the axial direction as the fermentation and drying drum 2 rotates, and
The tips of the crushing claws 45 on the left and right sides of the crushing device 7 are bent so as to be directed to the opposite sides in the left-right direction, so that the organic waste and soil fungus are at the central portion in the axial center of the fermentation drying drum. Since the processed products in the fermentation and drying drum 2 are closer to the central portion of the fermentation and drying drum 2 in the axial direction, the processed products can be stirred and mixed more favorably, and Does not easily reach the air supply port 61 and the air exhaust port 37, and the air supply port 61 and the air exhaust port 37 are less likely to be blocked by the processed material.

In particular, at the time of processing, as described above, by the rotation of the fermentation drying drum 2, the area 68 in which the treated material and the soil fungus are present is pushed in the rotational direction A of the fermentation drying drum 2 with respect to the circumferential direction. As shown by the phantom line in FIG. 5, the position is deviated in the rotation direction A, but the air supply port 61 and the exhaust port 37.
Is higher than the axis of the fermentation and drying drum 2,
Since the fermentation drying drum 2 is located in front of the vertical plane 62 extending vertically upward from the axis of the fermentation drying drum 2 in the rotation direction of the fermentation drying drum 2, the air supply port 61 and the exhaust port 37 are disposed in the fermentation drying drum 2. The soil bacteria existing region 68 and the fermentation drying drum 2 are in a state of facing each other in the radial direction.
The treated material and soil fungus do not easily reach the air supply port 61 and the air exhaust port 37, and the air supply port 61 and the air exhaust port 37 are less likely to be clogged.

As described above, when the temperature of the finished processed product is lowered, the driving of the gear motors 6 and 46 is once stopped, the attachment / detachment lid 17 is removed, and the opening 24 is opened. In this state, the carriage 11 is arranged below the fermentation / drying drum 2, and the gear / motor 6 drives the fermentation / drying drum 2 to rotate. As a result, as the fermentation and drying drum 2 rotates, the finished products inside the fermentation and drying drum 2 are sequentially transferred from the opening 24 to the carriage 1.
It falls into 1. During the above period, evaporated water in the fermentation drying drum 2 and dust that has dried and floated in the fermentation drying drum 2 enter the exhaust duct 10 through the exhaust port 37 and the exhaust opening 65. And dust is exhaust duct 10
The gas component is accumulated below the gas and is discharged to the outside.

The dust collected in the lower portion of the exhaust duct 10 can be easily taken out from the exhaust duct 10 by removing a cap (not shown). In addition, between the ring portions 22 and 23 of the fermentation drying drum 2 and the lids 4 and 5,
There is a gap, but this gap is filled with finished products,
Since it is sealed, the organic waste does not leak from the above-mentioned gap from the second treatment. In addition, in the crushing device of the above embodiment, the drive shaft is provided with the crushing pawl, but the drive shaft may be provided with the rotary cutter, or, instead of the drive shaft and the crushing pawl, an auger screw may be provided.

[0027]

As described above, according to the present invention,
By supplying hot hot air into the fermentation and drying drum,
Since it can be heated to the optimum activity temperature range of soil bacteria in an extremely short time and high-temperature treatment of organic waste can be performed, the fermentation drying treatment time can be significantly shortened, and furthermore, the fermentation treatment can be performed with one fermentation drying drum. Can be continuously dried.
The structure is simple. In particular, since the waste in the fermentation drying drum is agitated and mixed by rotating the fermentation drying drum itself, the waste and soil bacteria put in the fermentation drying drum are not mixed by the rotation of the fermentation drying drum. While being mixed with the inner surface of the fermentation and drying drum while being totally inverted, the mixture is agitated and mixed, and the entire temperature of the fermentation and drying drum 2 becomes high, and the inner surface of the fermentation and drying drum 2 and the waste material are mixed. Since it rotates, the waste is dried well.

When this is compared with an example in which a stirring and mixing screw that is driven to rotate is provided in the fermentation drying tank, in the above example, unlike the present invention, the stirring and mixing is partially stopped and Unlike the present invention, the waste does not circulate along with the inner surface of the fermentation and drying drum that has reached a high temperature, so that the waste cannot be dried as well as the present invention.
Further, in the present invention, by being driven to rotate about the horizontal axis, the organic waste and the soil fungus in the fermentation drying drum are crushed, and a crushing device for stirring and mixing is provided. Even if a large amount of waste is added to the waste, the waste can be easily crushed, and even if waste or soil fungus clumps are formed during fermentation or drying, it can be easily crushed and the fermentation drying process is good. Moreover, since not only stirring and mixing of waste and soil fungi by rotating the fermentation drying drum, but also stirring and mixing of waste and soil fungi can be performed by a pulverizer, the stirring and mixing of waste and soil fungi can be further improved. You can do well.

Further, as described in claim 2, the fermentation and drying drum is provided with air supply ports and exhaust ports on both sides in the axial direction, and both sides in the axial direction of the fermentation and drying drum are located outward in the axial direction. If it is a tapered taper section toward the end, waste and soil fungus on the tapered section of the fermentation and drying drum will be sent to the central portion in the axial direction of the fermentation and drying drum as the fermentation and drying drum rotates. Stirring and mixing of the substance and the soil bacterium are more favorably performed, and the waste and the soil bacterium are less likely to reach the air supply port and the exhaust port, and the air supply port and the air outlet are less likely to be blocked by the waste and the soil bacterium. Further, as in claim 3, the air supply port and the exhaust port are arranged above the axis of the fermentation drying drum, and are arranged in the rotational direction forward of the vertical plane extending vertically upward from the axis. Then, further, the air supply port and the exhaust port are less likely to be clogged, and as described above, if the air supply port and the exhaust port are positioned higher than the axis of the fermentation drying drum, they are discarded in the fermentation drying drum. Material and soil fungi can be added up to the vicinity of the axial center position where good stirring and mixing can be performed, and work efficiency can be improved.

Further, when the driving shaft is provided with the crushing claw so that the organic waste and the soil fungus are near the central portion in the axial center of the fermentation drying drum as in claim 5, the inside of the fermentation drying drum is The waste and soil fungi can be brought closer to the central portion in the axial direction, and the waste and soil fungi can be mixed and mixed more satisfactorily. If the exhaust port is provided, it is difficult for waste and soil bacteria to reach the air supply port and exhaust port, and it is difficult for the waste product and soil bacteria to block the air supply port and exhaust port. Also, claim 6
As described above, the axis of the crusher is lower than the axis of the fermentation drying drum, and if it is arranged in the rotation direction forward of the vertical plane extending vertically downward from the axis, the In addition, the waste and soil fungus in the fermentation and drying drum can be pulverized, and the waste and soil fungus can be mixed with stirring.
