Description

  The present invention relates to a fermentation treatment apparatus, and particularly to a fermentation treatment apparatus capable of fermenting and drying a processing raw material containing organic matter such as okara by the action of microorganisms and converting it into fertilizer and the like.

  Conventionally, in food manufacturing plants that process fisheries, meat, and vegetables, and produce food, waste containing a large amount of organic matter such as fish scraps, meat scraps, and vegetable scraps generated during the work process has been generated. Yes. In addition, at the manufacturing plant that manufactures tofu, one of the traditional processed foods in Japan, the “okara” that remains after squeezing soymilk is produced. This “okara” is used as an ingredient in various dishes, and has been rarely discarded. However, due to changes in dietary habits in recent years, the consumption of okara has been decreasing year by year, and the number of cases where it is used for livestock feed or certified as industrial waste and incinerated or landfilled is increasing.

  Therefore, in order to effectively use okara, a useful resource rich in organic matter, without discarding it as industrial waste, it is converted to useful substances such as compost using fermentative action by microorganisms. It is being used.

  The above technique is naturally carried out by those skilled in the art, and the applicant has no particular knowledge of the document describing the above technique at the time of filing this application.

  However, when trying to convert to fertilizer etc. using microorganisms, the following problems may occur. That is, the okara left after squeezing soy milk contained a lot of water. Therefore, since the odor (bad odor) from the surroundings diffuses in such a state, there are cases where it cannot be stored in a densely populated area such as a residential area. Furthermore, when left outside, okara comes to contain moisture again due to rain, and the above-mentioned odor may be emitted again. Therefore, it was necessary to reduce the moisture content contained in okara. In particular, when a large amount of moisture is contained, there is a problem that the bulk volume and weight increase and the transportation cost increases.

  Therefore, there has been a demand for an apparatus for drying organic matter (including garbage) containing a lot of moisture such as okara. However, there are few conventional drying apparatuses that are specially constructed, and the drying method is also exposed to high-temperature hot air using a heating burner or the like to evaporate moisture. As a result, it is necessary to continue heating with a heating burner until the drying is completely completed, and the amount of fuel such as heavy oil required for the operation of the heating burner becomes enormous, which greatly increases the cost of drying. There was an increase. Therefore, the processing cost of the tofu dealer etc. which must process these became a big burden.

  Therefore, in view of the above circumstances, the present invention can suppress the amount of fuel such as heavy oil required for drying as much as possible, and can efficiently ferment and treat raw materials for processing such as using the action of microorganisms. An object of the present invention is to provide a fermentation treatment apparatus that can be dried and converted to fertilizer and the like.

To solve the above problems, fermentation treatment apparatus of the present invention, the "cradle, has a substantially cylindrical shape, the micro organisms and storable storage space inside the processing material fermentation and drying process is performed by the microorganism A rotating drum horizontally disposed on the gantry, a rotation support means interposed between the gantry and the rotating drum, and rotatably supporting the rotating drum in a circumferential direction, and the rotation supported. A rotating agitation means for rotating the drum and agitating the stored processing material in the storage space; and an air supply pipe at least partially inserted in the storage space of the rotating drum, the heated air is sent through the trachea, with drying the treated material, a heating burner for raising the temperature of the storage space to the activity temperature you act actively said microorganism, said storage space of said rotary drum An exhaust part that has at least a part of the exhaust pipe inserted therein and exhausts the treated exhaust gas from the storage space through the exhaust pipe, wherein the exhaust part is exhausted from the storage space. An exhaust temperature measuring means for measuring the exhaust temperature of the exhaust gas, and the exhaust temperature of the treated exhaust gas, which is connected to the heating burner, is measured by the exhaust temperature measuring means and is affected by the heat of fermentation generated by the fermentation action of the microorganisms And a heating air adjustment control means for intermittently adjusting the delivery of the heating air by the heating burner, the heating burner,
In accordance with the heating air adjustment control means, the heating air supply means is provided mainly with intermittent heating means for intermittently delivering the heating air.

  Here, the rotation support means includes, for example, a rotation roller that is formed so as to be able to contact a drum outer peripheral surface of a horizontal rotation drum and rotates following the rotation of the rotation drum. As a result, the rotary drum installed horizontally can be rotated on the spot in the circumferential direction with the cylindrical axis direction as the rotation axis. Further, the rotation agitation means includes a drive motor that generates a driving force for rotating the supported rotating drum, a driving transmission unit that transmits the driving force by the driving motor to the rotating drum through a gear or the like. As a result, by operating the drive motor, the drive force is transmitted to the rotary drum supported by the rotation support means. More specifically, the drive gear portion attached to the tip of the drive shaft that is pivotally supported by the drive motor can mesh with the rotary gear portion that is fitted along one end of the drum outer peripheral surface of the rotary drum. And the rotation of the drive motor is transmitted to the rotation gear portion through the drive gear portion.

In addition, the heating burner sends high-temperature heated air to the storage space through a hot air tube, evaporates the moisture contained in the processing raw material introduced into the storage space together with the microorganisms, and dries it. Here, the heating burner can use a conventionally well-known configuration and apparatus, and is operated by burning petroleum fuel such as heavy oil. Further, the heating burner is provided with intermittent delivery means for intermittently delivering heated air. Thus, when the heated air is sent to the storage space and reaches an activation temperature ( for example, 80 ° C. to 90 ° C. ) at which the microorganisms actively act (activate), the delivery of the heated air by the heating burner is stopped. After that, when the exhaust temperature of the treated exhaust gas falls below the activation temperature (for example, 70 ° C.) by an exhaust temperature measuring means such as an exhaust temperature sensor for detecting the exhaust gas temperature of the treated exhaust gas, the heating burner is turned on again. Operate and send heated air to the storage space. Thereby, the combustion amount of heavy oil can be suppressed compared with the conventional drying apparatus which operates a heating burner continuously. In particular, the microorganisms that are put into the storage space generate their own fermentation heat during the fermentation process. As a result, the temperature of the storage space does not drop significantly. Therefore, the operation time of the heating burner can be shortened.

  Therefore, according to the fermentation treatment apparatus of the present invention, the substantially cylindrical rotary drum that is rotatably supported by the rotation support means and is provided horizontally on the gantry is rotated by the rotation drive means. At this time, the processing raw material to be processed is stored together with the microorganisms in the internal storage space, and the processing raw material is vigorously stirred in the storage space by the rotation of the rotating drum. At this time, since high-temperature heated air is sent from the heating burner through the hot air tube, the moisture contained in the processing raw material evaporates in the storage space, and is discharged from the discharge portion to the outside of the rotating drum together with the processed exhaust. Thereby, the processing raw material is dried. Furthermore, microorganisms are put into the storage space. By introducing a microorganism having the property of being activated at a relatively high temperature, the fermentation and decomposition action of the microorganism is activated along with drying by sending heated air.

Here, the microorganisms introduced into the storage space are not particularly limited as long as the raw material for treatment is decomposed by the action of microorganisms, fermented and dried. However, since the storage space is temporarily heated to a high temperature by the above-described heated air, it needs to have a certain degree of heat resistance (for example, resistance to a high temperature of about 80 ° C. to about 100 ° C.) . The microorganism used in the present invention may be a kind of photosynthetic bacteria group called “NB bacteria”. This NB bacterium is an indigenous bacterium originally present in the soil, and a NB bacterium collected from the soil is propagated under moderate environmental conditions.

  Thereby, a process raw material is fermented and dried by the effect | action by microorganisms, and is converted into compost etc. At this time, by rotating the rotating drum, the agitation with the microorganisms and the contact with the heated air to be sent out become good, and the progress of the processing becomes quick. Furthermore, since the activity of the microorganisms is maintained at a certain temperature, the heated air by the heating burner can be intermittent. That is, when the storage space is placed in an environment where the activity of the target microorganism at around 80 to 100 ° C. is activated, the operation of the heating burner is stopped, while the temperature in the storage space falls below the above temperature range. In this case, the operation of operating the heating burner can be repeated again. Thereby, the fuel consumption required for the operation of the heating burner can be reduced as compared with the conventional case. In addition, since the temperature around 80 to 100 ° C. is a temperature at which existing bacteria such as EM bacteria are almost killed, a situation where only NB bacteria not mixed with other bacteria are active is created. Is possible.

  In addition, the amount of heated air delivered by the heating burner can be adjusted in conjunction with the exhaust temperature of the processed exhaust discharged from the exhaust pipe. That is, the fermentation treatment apparatus of the present invention can ferment and dry the treated raw material by the action of microorganisms introduced into the storage space, in addition to simple drying of the treated raw material by heated air. Therefore, if the exhaust temperature is monitored and the temperature is such that the activity of the microorganisms is activated, the heated air is stopped, the agitation by the rotation of the rotating drum, and the microorganisms activated by the high-temperature air in the storage space It becomes possible to perform a fermentation and a drying process by this activity. That is, as in the past, fuel such as heavy oil that has been wasted can be reduced by continuously using a heating burner or the like until the processing raw material is dried. Thereby, it becomes possible to suppress the energy concerning fermentation and drying of a processing raw material to resource saving.

Furthermore, in addition to the above-described configuration, the fermentation treatment apparatus of the present invention is “opened on the side peripheral surface of the rotating drum, and stores the treatment raw material introduced from above in the storage space, and also performs fermentation and drying. A throwing / discharging part that drops the treated fermented product downward from the storage space and discharges it to the outside, an opening / closing lid part that can open and close the throwing / discharging port of the throwing / discharging part of the rotating drum, A hopper provided at a position facing the loading / discharging portion from above, and having a feeding portion for feeding the processing raw material into the storage space of the rotating drum, wherein the feeding portion extends from the main body of the hopper to the rotating drum Hopper displacement means having an outer tube portion extending in the direction of the inner tube, an inner tube portion inscribed in the outer tube portion, and a telescopic portion for sliding the inner tube portion while maintaining contact with the outer tube portion And when the processing raw material is charged, Enters the storage space of the drum, said during rotation of the rotary drum is assumed to be displaced "at a position spaced apart from the rotating drum.

  Therefore, according to the fermentation treatment apparatus of the present invention, the throwing / discharging part provided with the throwing / discharging part opened to the drum side peripheral surface of the rotating drum, and the opening / closing lid part capable of closing the throwing / discharging part. Therefore, it is possible to input raw materials for treatment and discharge fermented products. Here, at least one of the throwing / discharging part and the opening / closing lid part may be provided on the rotating drum, but it is easy to input the processing raw material into the storage space and discharge the fermented material from the storage space. Therefore, for example, a pair (one set) provided along the longitudinal direction is particularly suitable. Thereby, by opening the throwing / discharging part by the opening / closing lid part, it is possible to store the processing raw material introduced from the hopper inside, and to drop the fermentation processed product downward, from the storage space It is possible to discharge. In such a case, by rotating the rotating drum, the throwing / discharging portion is opened upward so as to face the hopper loading port of the hopper when being loaded, while the throwing / discharging port is directed downward when discharging. At this time, a collection bag or the like is installed in advance below the throwing and discharging port for collecting the fermented material.

Furthermore, hopper displacement means for displacing the hopper loading portion between the loading position and the separation position is provided. Here, the hopper displacement hand stage, those from the body of the hopper and an outer tube portion that extends in the direction of the rotary drum, and the inner pipe section inscribed in the outer tube portion, the outer tube portion and the inner tube portion It has an expansion / contraction part that is attached to the contact surface and slides the inner pipe part while maintaining contact with the outer pipe part. As the expansion / contraction section, one that displaces the hopper insertion section opening using an expansion / contraction means utilizing a conventionally known rack and pinion mechanism and a drive motor is used. This ensures that at the time of introduction of the treatment material, is advanced inside to the hopper inlet of the storage space can be dropped processing material from the hopper from, without external processing raw material of the rotating drum is scattered, reliably turned can do. On the other hand, at the time of rotation of the rotating drum, the rotation of the rotating drum is not hindered by displacing the hopper insertion port to the separation position.

  Furthermore, in addition to the above-described configuration, the fermentation treatment apparatus according to the present invention may include: “The rotating drum includes a stirring blade that protrudes from an inner peripheral surface of the drum that is in contact with the storage space with one end inclined toward the rotating circumferential direction. It may be provided.

  Therefore, according to the fermentation treatment apparatus of the present invention, by having the stirring blade on the inner circumferential surface of the circle, the storage space is maintained in a state where the processing raw material stirred by rotation is held between the stirring blade and the inner circumferential surface of the circle. It will be conveyed to the upper position. At this time, since the tip of the stirring blade is formed to be inclined in the rotation direction, the space volume generated between the stirring blade and the inner circumferential surface of the circle becomes large, and more processing raw materials are conveyed to the upper position of the storage space. can do. As a result, the stirring motion of the treated raw material becomes intense, the probability of coming into contact with the heated air that is sent out increases, and the chance of contact with microorganisms also increases. Thereby, the efficiency of drying and fermentation by the fermentation treatment apparatus of the present invention is improved.

  Furthermore, in addition to the above-described configuration, the fermentation treatment apparatus according to the present invention is “fermented and dried by the microorganisms using okara left after squeezing soymilk as the treatment raw material”.

  Therefore, according to the fermentation processing apparatus of the present invention, “okara” is used as a processing raw material, and processing is performed by causing microorganisms to act on the okara. Thereby, it becomes possible to manufacture fertilizer etc. using okara as a processing raw material. The obtained fermented product is not only used as a fertilizer as described above, but also, for example, by spraying it on malodorous substances such as chicken manure, to eliminate the deodorizing action by the action of microorganisms, or to soil suitable for crops. It can also be used as a soil modifier for conversion. Moreover, the smell of excrement can also be suppressed by using as it is as feed for livestock. As a result, it becomes possible to dry the okara and further use the fermented product obtained by the fermenting process for various useful applications, such as a tofu manufacturing plant that has conventionally required a cost for disposal. The processor can reduce the burden of such costs and can reuse okara as a more useful resource.

As an effect of the present invention, the fermentation processing apparatus can ferment and dry processing raw materials such as okara with the heated air sent out while rotating the rotating drum. Furthermore, okara etc. can be converted into useful substances such as compost by the action of microorganisms. At this time, by effectively using the heat of fermentation of the microorganism occurs, the delivery of the heated air by heating burners as being intermittent, microbial activity becomes possible to maintain the temperature range you activated heavy oil The consumption of petroleum fuel such as can be reduced as compared with the conventional drying apparatus.

Here, FIG. 1 is explanatory drawing which shows schematic structure of the fermentation processing apparatus 1 of this embodiment, FIG. 2 is explanatory drawing which shows schematic structure of the fermentation processing apparatus 1, and FIG. FIG. 4 is a perspective view showing the configuration of the drum 2, FIG. 4 is an explanatory diagram showing the configuration inside the rotary drum 2, and FIG. 5 is an explanatory diagram showing the telescopic mechanism 4 of the hopper 3. Here, in order to simplify the description, in FIG. 2, a partial configuration of the rotation driving unit 10 and a configuration of the gantry 5 on which the rotary drum 2 is horizontally supported are omitted in FIG. 4. .

  As shown in FIG. 1 to FIG. 5, the fermentation treatment apparatus 1 of the present embodiment has a frame 5 having a substantially rectangular parallelepiped shape arranged on the installation surface F, and a property in which activity is active in the vicinity of 80 ° C. to 100 ° C. Of the rotary drum 2 having a cylindrical shape like a drum can, and the gantry 5 and the rotary drum 2. Rotation support portions 9a and 9b that are interposed between them and support the rotary drum 2 horizontally with respect to the gantry 5 so as to be rotatable in the circumferential direction (corresponding to the direction of arrow A in FIGS. 2 and 4). A rotary drive unit 10 for rotating the rotary drum 2, a heating burner 13 for sending high-temperature (for example, about 200 ° C.) heated air 12 to the storage space 8 of the rotary drum 2 through the hot air tube 11, and an exhaust pipe 14 through the storage space 8 And a discharge portion 16 for discharging 15 is configured mainly provided.

  Here, the configuration of each part will be described in more detail. The gantry 5 is connected to the six vertical frames 17 erected on the installation surface F so as to bridge the vicinity of the upper and lower ends of the vertical frame 17. The horizontal frames 18a and 18b thus formed and the reinforcing frame 19 for reinforcement that is connected by bridging the vicinity of the center of the horizontal frame 18a on the longitudinal side adjacent to each other are formed in a rectangular parallelepiped shape as a whole. Here, each of the frames 18 and the like is made of a metal material, and the connecting portions connected orthogonally to each other are fixed by a conventionally known fixing means such as welding or a bolt and nut structure (illustrated). Is omitted). And it has the intensity | strength which can fully endure the weight of the rotating drum 2 etc. which are mounted in the mount frame 5.

  On the other hand, a first rotation support portion 9 a is provided in the vicinity of the approximate center of the horizontal frame 18 b on the short side of the gantry 5 and the reinforcing frame 19 positioned on the upper surface side of the gantry 5. As shown in FIG. 4 and the like, the first rotation support portions 9a are arranged in parallel with each other, and the roller outer peripheral surface 20 comes into contact with the reinforcing portion 2a protruding from the drum outer peripheral surface 27 of the rotary drum 2. A rotation support roller 21 that supports the rotary drum 2 from below, and a guide portion 23 that supports the roller shaft 22 of the rotation support roller 21 and supports the rotation support roller 21 so as to follow the rotation of the rotation drum 2. It has. On the other hand, on the other horizontal frame 18b (corresponding to the left end side in FIG. 1), the above-mentioned rotation support roller 21 is provided with a drum side gear 24 (details will be described later) mounted on the rotary drum 2. A second rotation support portion 9b replaced by a support gear 26 having meshable gear teeth 25a is provided. Here, since the other structure of the 2nd rotation support part 9b is substantially the same as the structure of the above-mentioned 1st rotation support part 9a, the description is abbreviate | omitted here. Here, the 1st rotation support part 9a and the 2nd rotation support part 9b are equivalent to the rotation support means in this invention.

  As a result, a state in which the rotary drum 2 is rotatably supported from below by the pair of rotation support rollers 21 and the pair of support gears 26 is created. In particular, since the support gear 26 is formed so as to be able to mesh with the drum-side gear 24, the rotation of the rotary drum 2 is stabilized.

  On the other hand, the rotating drum 2 has a cylindrical shape and is made of a metal material in which a storage space 8 in which the carp 7 is stored is formed. A drum-side gear 24 is fitted at one end of the drum outer peripheral surface 27 and at a location facing the support gear 26 of the second rotation support portion 9b. Here, the drum side gear 24 is formed with a plurality of gear teeth 25b projecting radially from the center. Further, the rotary drum 2 has two throwing / discharging portions 29 formed so as to penetrate the storage space 8 from the drum outer peripheral surface 27 and an opening / closing lid portion 30 that allows the throwing / discharging portion 29 to be opened and closed. ing. Here, when throwing 7 into the storage space 8, the throwing / discharging unit 29 is rotated so as to be positioned on the upper surface side of the rotary drum 2, and then opens the opening / closing lid 30, and the storage space 8 and the outside And communicate with each other. On the other hand, when discharging the compost 31 that has been processed from the rotating drum 2, the throwing / discharging unit 29 is rotated so as to be positioned on the lower surface side of the rotating drum 2, and then the opening / closing lid 30 is opened. As a result, the compost 31 stored in the storage space 8 falls downward. At this time, a collection bag 32 (see FIG. 1) made of vinyl or the like for collecting the compost 31 is attached to the gantry 5 that faces the throwing / discharging unit 29, and the collection bag 32 is filled with the compost 31 for bagging. It can be in the state. Here, the compost 31 corresponds to the fermented product in the present invention.

  Further, a stirring blade 34 is attached to the drum inner circumferential surface 33 of the rotary drum 2 so that the tip thereof is inclined in the rotational direction of the rotary drum 2. Thereby, when the rotating drum 2 rotates, the microorganisms 6 and okara 7 stored therein are lifted up to the vicinity of the upper surface of the rotating drum 2 by the stirring blades 34 and dropped from the position toward the bottom surface side. As a result, the stirring efficiency is improved. Moreover, the timing and contact area of the heated air 12 delivered from the heating burner 13 will increase, and the fermentation and drying processes will be efficient.

  Further, the heating burner 13 for sending the heated air 12 through the hot air tube 11 is not particularly limited, but an existing burner using heavy oil or the like can be used. On the other hand, the discharge unit 16 includes a temperature sensor 16a that detects the exhaust temperature of the processed exhaust 15 sent from the storage space 8 through the exhaust pipe 14, and is heated by the heating burner 13 according to the exhaust temperature detected by the temperature sensor 16a. A heated air control unit 35 that controls ON / OFF of the delivery of the air 12 is provided. The heating burner 13 includes the intermittent delivery mechanism 36 that adjusts the delivery of the heated air 12 based on the control signal of the heated air control unit 35. Here, the temperature sensor 16a corresponds to the exhaust temperature measuring means in the present invention, the heated air control unit 35 corresponds to the heated air adjustment control means in the present invention, and the intermittent feed mechanism 36 of the heating burner 13 in the intermittent feed in the present invention. Corresponds to means.

Furthermore, the fermentation treatment apparatus 1 according to the present embodiment includes a hopper 3 for putting Kara 7 into the storage space 8 of the rotary drum 2. Here, a specific configuration of the hopper 3 will be described. A hopper having an opening 37 that opens upward and into which Okara 7 is placed and a hopper holding portion 38 that is formed so that the side surface expands upward. A main body 39 and a hopper input portion 40 extending in the direction of the rotary drum 2 for supplying okara 7 to the rotary drum 2 are provided. Further, the hopper charging unit 40 enters the storage space 8 and can be expanded and contracted in the vertical direction between a charging position FP for loading okara 7 and a separating position SP for separating the hopper charging unit 40 from the rotating rotary drum 2. A flexible telescopic mechanism 4 (see FIG. 5). The telescopic mechanism 4 has a connected outer tube portion 42 fixed to the hopper body 39 and an inner tube portion 43 formed so that the inner tube surface 43 a is inscribed in the outer tube surface 42 a of the outer tube portion 42. In addition, it has an expansion / contraction part that slides and expands / contracts while maintaining the contact of the inner pipe part 43 with the outer pipe part 42. Here, the extendable part is realized by using an existing rack and pinion mechanism or a drive mechanism such as an actuator. Thereby, the hopper throwing-in part 40 can change the full length as needed, and can displace between throwing position FP and separation position SP. As a result, when throwing Okara 7 from the hopper 3 into the storage space 8, the fermentation mechanism 1 is extended by extending the hopper loading portion 40 to the maximum length by the telescopic mechanism 4 and allowing the loading end 40 a to enter the storage space 8. The possibility that the okara 7 scatters to the outside is reduced. On the other hand, the contraction of the hopper insertion portion 40 to the minimum length by the expansion / contraction mechanism 4 prevents the rotation of the rotary drum 2 from being hindered. Here, the telescopic mechanism 4 corresponds to the hopper displacement means in the present invention.

  Further, the rotation drive unit 10 of the fermentation treatment apparatus 1 of the present embodiment has a drive gear 45 having gear teeth 25c formed so as to be able to mesh with the drum side gear 24 of the rotary drum 2 described above, and a drive connected to the drive gear 45. A shaft 46 and a drive motor 47 for rotating the drive shaft 46 are provided. Note that a control device, a power source, and the like for controlling the operation of the drive motor 47 are not shown in order to simplify the description. Here, the rotation drive part 10 is equivalent to the rotation stirring means in this invention. Thereby, the rotational force generated by the drive motor 47 is transmitted to the drum-side gear 24 of the rotary drum 2 through the drive shaft 46 and the drive gear 45, and the rotary drum 2 can be rotated with the cylindrical axis direction as the rotation axis.

  Next, an example of use of the fermentation treatment apparatus 1 of the present embodiment will be described. First, okara 7 corresponding to the processing raw material temporarily stored in the hopper body 39 of the hopper 3 is put into the storage space 8 of the rotary drum 2. At this time, the extension mechanism 4 of the hopper 3 is used to extend the hopper input part 40 to the input position FP. On the other hand, the rotating drum 2 is rotated so that the throwing / discharging portion 29 is positioned on the upper surface, and further the opening / closing lid portion 30 is opened. Thereby, the extended hopper throwing-in part 40 can enter the storage space 8 through the throwing / discharging part 29. Then, Okara 7 is dropped from the hopper 3 into the storage space 8. At this time, the microorganism 6 is stored in the storage space 8 in advance. That is, the compost 31 is not completely discharged from the throwing and discharging unit 29 when the fermentation treatment apparatus 1 is used last time, but a predetermined amount is left in the storage space 8. The compost 31 is rich in microorganisms 6 used when fermenting the okara 7. Therefore, it is not necessary to mix the microorganism 6 every time Okara 7 is charged. Okara 7 has a very high water content and may show about 85%. Then, after the okara 7 is completely charged, the hopper loading portion 40 is contracted using the telescopic mechanism 4, and the loading end 40a is separated from the drum outer peripheral surface 27 and displaced to the separation position SP. Thereby, the hopper throwing-in part 40 does not inhibit rotation of the rotating drum 2. Then, the throwing / discharging portion 29 is closed by the opening / closing lid portion 30. Thereby, it will be in the state where a part of compost 31 containing the kara 7 and the microorganisms 6 existed in the internal storage space 8.

  Thereafter, the rotation drive unit 10 is operated, and the rotation of the drive motor 47 is transmitted to the rotary drum 2 through the drive gear 45. At this time, since the drive gear 45 is formed so as to be able to mesh with the drum-side gear 24 of the rotary drum 2, the gear teeth 25 b and 25 c mesh with each other to transmit the rotational force. Furthermore, since the rotary drum 2 is supported by the rotation support portions 9a and 9b, the rotary drum 2 rotates in the circumferential direction with the cylindrical axis direction as the rotation axis. At this time, in the storage space 8 inside the rotary drum 2, the stirring of 7 is performed according to the rotation. Here, on the drum inner peripheral surface 33 of the rotating drum 2, several stirring blades 34 are provided so as to project the tip in the rotational direction. As a result, a holding space 48 is formed between the drum inner circumferential surface 33 and the stirring blade 34 in which Kara 7 and the like are held. Then, the okara 7 stored in the holding space 48 moves to the upper position of the rotary drum 2 along the rotation while being held. Here, since the tip is inclined in the circumferential direction, the holding amount of the forehead 7 held in the holding space 48 can be increased as much as possible. Then, the okara 7 that has reached the upper position of the rotary drum 2 falls downward according to gravity. At this time, the fall distance substantially matches the diameter length of the rotating drum 2. Therefore, the efficiency of stirring in the rotating drum 2 is increased.

  On the other hand, simultaneously with the operation of the rotary drive unit 10, the heating air 12 is started to be sent out by the heating burner 13. Here, the heated air 12 is sent to activate the movement of the microorganisms 6 stored in the storage space 8 and to efficiently perform fermentation and drying of the okara 7. As described above, the microorganism 6 used in the present embodiment is one that works in a relatively high temperature region among the activities of microorganisms near 80 to 100 ° C. Then, the inside of the storage space 8 is warmed (or heated) by the sent heated air 12, and the storage space 8 becomes a temperature suitable for the activity of the microorganism 6. Here, the heated air 12 is supplied to the storage space 8 through the hot air tube 11 connected to the heating burner 13. On the other hand, the exhaust pipe 14 is inserted into the storage space 8 from the side opposite to the side through which the hot air pipe 11 is inserted. And the heating air 12 sent out from the heating burner 13 loses thermal energy in the storage space 8, and is discharged at a temperature lower than the temperature at the time of sending. The exhaust gas temperature is detected by a temperature sensor 16 a provided in the discharge unit 16.

  Here, when the temperature sensor 16a detects that the exhaust gas temperature has reached a preset temperature or higher (for example, 90 ° C. or higher), the heating air control unit 35 of the discharge unit 16 operates. Then, the intermittent delivery mechanism 36 of the heating burner 13 stops the delivery of the heated air 12. At this time, the rotation of the rotary drum 2 is continued. Thereafter, the temperature sensor 16a monitors the exhaust temperature of the processed exhaust 15 after the operation of the heating burner 13 is stopped. When it is detected that the exhaust temperature has dropped below a preset temperature (for example, 75 ° C. or lower), the heated air control unit 35 and the intermittent delivery mechanism 36 are acted again, and the heated air 12 is delivered by the heating burner 13. To start. Here, the temperature for determining ON / OFF of the operation of the heating burner 13 is not particularly limited, but it is preferable to determine the temperature based on the temperature at which the input microorganism 6 actively operates. Thereby, since the operation of the heating burner 13 is performed intermittently, it is not necessary to always burn the heating burner as in the conventional case. And when the fermentation process of the microorganism 6 is performed, since the heat of fermentation is generated, the exhaust temperature does not drop rapidly. Thereby, the quantity of the heavy oil used for combustion of the heating burner 13 can be suppressed to the necessary minimum.

  Then, by continuing the rotation of the rotary drum 2 and the intermittent operation of the heating burner 13 described above, it is possible to dry the inner side 7 in the storage space 8. Furthermore, from the Okara 7 rich in organic matter by the action of the microorganism 6 introduced at the same time, it can be converted to a useful compost 31 that can be fertilized on a field and the like to grow farm products. That is, the okara 7 that has conventionally been incinerated or disposed of as industrial waste can be utilized as a resource. Here, in the fermentation treatment apparatus 1 of the present embodiment, the fermentation and drying treatment of Okara 7 described above is performed in one cycle for 24 hours. Then, after 24 hours have passed since the okara 7 was charged, the throwing / discharging portion 29 of the rotating drum 2 is rotated so as to come to the lower surface, and the opening / closing lid portion 30 is opened. Thereby, the compost 31 in the storage space 8 falls downward and is discharged from the rotating drum 2. At this time, as described above, the collection bag 32 is provided so as to face the throwing / discharging portion 29. Furthermore, also in this case, a part of the generated compost 31 is left in the storage space 8 for the next fermentation and drying of the okara 7.

  As described above, by using the fermentation treatment apparatus 1 of the present embodiment, the okara 7 that has conventionally been subjected to incineration or the like can be converted into a useful compost 31. At this time, the moisture of 7 can be efficiently dried after using the heat of the heated air 12 and the fermentation heat of the microorganism 6. In particular, by using a bacterial species that activates the microorganism 6 to be used at about 80 ° C. to 100 ° C., the heating burner 13 is acted intermittently, and the temperature in the storage space 8 is easily activated by the microorganism 6. Can be maintained at temperature. As a result, the usage amount of heavy oil or the like can be suppressed, and the operating cost can be greatly reduced as compared with those using a conventional microorganism or a fermentation apparatus or drying apparatus using only a heating burner.

  In addition, since the hopper loading portion 40 of the hopper 3 for loading the kara 7 into the rotary drum 2 is formed to be displaceable, there is no possibility of scattering outside when the kara 7 is loaded.

  The present invention has been described with reference to preferred embodiments. However, the present invention is not limited to these embodiments, and various modifications can be made without departing from the spirit of the present invention as described below. And design changes are possible.

  That is, in the present embodiment, "Okara 7" after squeezing soy milk as a processing raw material has been shown to produce the compost 31, but not limited to this, and contains abundant organic matter, Any material that can be fermented and dried by the microorganism 6 may be used. Furthermore, although it illustrated about what is used as the compost 31 as a fermented processed material, it is not limited to this, As mentioned above, the deodorant using the deodorizing action of microorganisms, livestock feed, soil improvement It can be used as a raw material for chemicals and fertilizers.
