Description

Technical Field

[0001] The present invention relates to a portable mobile charcoal smoking device.

Background Art

[0002] In our country, rice husks are an important resource, but farmers are troubled by the disposal of 2 million tons of rice husks every year, and most of them are currently incinerated. However, in the past, rice husks could be incinerated by so-called open burning, but in recent years, regulations have become stricter, and open burning tends to be prohibited. Also, even when incinerating rice husks at an incineration plant or the like, a large amount of carbon dioxide is generated, which hinders measures against global warming.

[0003] Therefore, in recent years, research and development have been underway to reduce carbon dioxide emissions from rice husk incineration and to effectively utilize rice husks. For example, Patent Document 1 discloses a device that uses the heat generated by incinerating rice husks for heating an agricultural greenhouse. Also, Patent Documents 2 and 3 disclose devices for producing rice husk charcoal by steaming rice husks (see FIG. 11).

[0004] Rice husk charcoal has the effects of improving the drainage of soil, neutralizing soil, and repelling pests, and is used as a soil improvement material for agricultural land. Also, mineral components such as silica, silicic acid, copper, manganese, iron, and potassium contained in rice husks are more easily separated by making them into charcoal, and are expected to be used in various fields of agriculture and industry.

[0005] The charcoal smoking devices according to Patent Documents 2 and 3 have a configuration of "an inlet for charging a charcoal smoking material, a cylindrical member having one end side communicating with the inlet, extending in a substantially horizontal direction, and having an outlet provided on the other end side, a screw conveyor provided inside the cylindrical member for sending the charcoal smoking material charged from the inlet to the outlet, and provided between the inlet and the outlet for firing the charcoal smoking material". The configuration according to Patent Document 3 further provides a firing unit, and provides a charcoal smoking device that can fire charcoal smoking materials such as rice husks uniformly and efficiently (see FIG. 11).

[0006] In charcoal production, the location of the rice husk delivery site, the location of the charcoal production equipment, and the location of the charcoal storage facility are crucial. If these locations are far apart, labor costs increase during production, raising cost-effectiveness issues. Furthermore, because the specific gravity of rice husks is low (approximately 0.1), a full 10-ton truck only amounts to about 1 ton, making it unsuitable for transportation from a cost-effectiveness standpoint.

[0007] Therefore, one of the inventors of the present invention invented a high-performance kiln-type charcoal production apparatus, etc., for producing charcoal on-site, such as in farmland where rice husks are generated (Patent Document 4). The invention described in Patent Document 4 provides a charcoal production apparatus, a charcoal production method, and a charcoal production system that do not generate soot, toxic gases, or foul odors in the process of producing charcoal from charcoal materials, and that reduce the cost of producing charcoal.

[0008] However, as mentioned above, it is preferable to install the charcoal production equipment in the same location as the rice husk delivery area and the charcoal storage area, and it is not suitable for sharing. Therefore, individual farmers, or a small number of neighboring farmers, need to purchase or otherwise acquire the equipment and install it on their respective farms.

[0009] However, this type of charcoal production equipment is not mass-produced, and is currently too expensive for individual farmers to purchase. Furthermore, it is difficult for individual farmers to install rice husk storage facilities, charcoal storage facilities, and the charcoal production equipment on their respective farms.

[Effects of the Invention]

[0040] (1) Mobile charcoal manufacturing equipment The mobile charcoal production apparatus according to the present invention includes at least a rotary kiln and an external combustion chamber, which can be fixed to a fixed transport body such as a container or trailer, and other components of a charcoal production system can be loaded onto it. Therefore, the mobile charcoal production apparatus of the present invention can be loaded and unloaded onto means of transport such as automobiles, trains, ships, and airplanes, like cargo loaded onto these fixed transport bodies, and the charcoal production apparatus together with the fixed transport body can be transported to a destination by these means of transport.

[0041] Thus, the mobile charcoal production apparatus of the present invention can be transported to farms or other locations where charcoal materials are stored, unloaded from the transport vehicle at the site, and the charcoal production apparatus, along with its fixed transport body, can be installed there. Therefore, farmers with limited financial resources can jointly own or lease the mobile charcoal production apparatus of the present invention and produce charcoal at low cost.

[0042] To produce charcoal, in addition to the charcoal production equipment, devices necessary for the charcoal production system, such as an automatic charcoal material supply machine, a charcoal suction device, and a cyclone separator, are required. However, the mobile charcoal production equipment of the present invention allows these charcoal production system devices to be loaded onto a fixed transporter along with the fixed charcoal production equipment. Therefore, the fixed transporter can be loaded or stored on a means of transportation such as a freight car, or towed, to a site such as farmland where charcoal materials such as rice husks are stored.

[0043] Furthermore, the mobile charcoal production apparatus of the present invention, once transported to a site such as farmland, can be unloaded from the means of transport along with its fixed transport body, or detached from the means of transport and installed at the site along with its fixed transport body. Since other charcoal production system equipment can also be unloaded and installed at the site, charcoal can be produced using charcoal materials such as rice husks stored at that site. (2) Embodiment of a mobile charcoal production apparatus

[0044] The rotary kiln type charcoal production apparatus according to the present invention involves loading a considerable amount of charcoal material into a rotary kiln and stacking the charcoal material inside the rotary kiln to fire the charcoal. As a result, the air barrier effect of the upper layer of stacked charcoal material creates a low-oxygen state in the lower layer, resulting in firing conditions suitable for steaming.

[0045] In other words, conventional charcoal production processes require the entire kiln to be kept in a low-oxygen state, which causes large amounts of soot and toxic gases to be generated. However, the rotary kiln type charcoal production apparatus of the present invention does not require the entire rotary kiln to be kept in a low-oxygen state. In the upper layer of the stacked charcoal material, the charcoal material can be burned at high temperature in a smokeless state under sufficient oxygen concentration. As a result, the soot generated in the lower layer during the baking process can also be burned together with the charcoal material in the upper layer, significantly reducing the generation of soot and toxic gases.

[0046] Furthermore, as described above, the upper layer of the stacked charcoal material undergoes high-temperature, smokeless combustion under sufficient oxygen concentration, which acts as a heat source, eliminating the need for a heating device that was required in conventional charcoal production equipment. As a result, the manufacturing cost of the charcoal production equipment can be reduced, and since fuel costs for heating are also eliminated, the cost of producing charcoal can also be reduced.

[0047] Furthermore, as the rotary kiln rotates, the charcoal material is lifted along the inner surface of the kiln, and by adjusting the rotation speed, the upper and lower layers of the charcoal material can be replaced as needed. This allows the charcoal material to burn evenly, eliminating uneven burning and ensuring uniform quality of the fired charcoal.

[0048] The rotary kiln type charcoal production apparatus according to the present invention is equipped with an air supply means and configured to supply air with a sufficient oxygen concentration into the rotary kiln. Therefore, while conventional charcoal production apparatuses restrict the airflow for steaming, in the rotary kiln of the present invention, the temperature of smokeless combustion of the stacked charcoal material rises, significantly reducing the generation of soot and toxic gases. Furthermore, this heat source raises the firing temperature of the charcoal material, improving the efficiency of charcoal production.

[0049] Furthermore, a flow of air is created from the chimney installed in the external combustion chamber, drawing air in from inside the rotary kiln. This reduces the pressure inside the rotary kiln, allowing air to be drawn in from the outside. As a result, an airflow is created from the discharge side of the rotary kiln, passing through the inside of the rotary kiln and being exhausted from the chimney in the external combustion chamber. This air cools the charred coal, eliminating the need for the conventional cooling process and improving the efficiency of charred coal production.

[0050] The rotary kiln type charcoal production apparatus of the present invention is configured such that the rotary kiln is tilted at a predetermined angle relative to the floor of the fixed transport body, from its connection point toward the discharge point. As a result, the charcoal material is automatically pushed toward the discharge point while being burned and can be accumulated in a charcoal storage container placed below the discharge point.

[0051] One or more axial partition plates are installed on the inner surface of the rotary kiln to divide the charcoal material along its central axis, thereby dividing the inside of the rotary kiln into one or more internal combustion chambers. As a result, the thickness of the charcoal material layer can be maintained above a certain level, and the upper layer blocks air, maintaining the stability of the steaming process in the lower layer. This improves the efficiency of charcoal production and also makes it easier to adjust the firing time of the charcoal material.

[0052] Furthermore, multiple stirring plates were installed on the inner surface of the rotating kiln to agitate the charcoal material in the direction of its rotation. This allows for easy and reliable exchange between the upper layer of charcoal material, which is burning at high temperature without smoke, and the lower layer, which is in a steaming state. This eliminates uneven burning of the charcoal and ensures uniform quality.

[0053] In conventional charcoal production equipment, once the calcined charcoal is deposited in the charcoal tank, it needs to be cooled. In contrast, the rotary kiln type charcoal production system of the present invention transfers the calcined charcoal from the charcoal storage container to the cyclone separator and charcoal intake container via the charcoal transfer pipe. As a result, low-temperature outside air acts on the charcoal transfer pipe, cooling the mixed charcoal as it is being transferred through the pipe. (3) Charcoal production system

[0054] (Charcoal production system using a rotary kiln type charcoal production apparatus) The charcoal production system according to the present invention comprises a rotary kiln-type mobile charcoal production apparatus, an automatic charcoal material supply machine that supplies charcoal material moved from a charcoal material container into the charcoal production apparatus, a charcoal storage container positioned below the discharge section of the charcoal production apparatus to accumulate charcoal, a charcoal suction device that sucks up the accumulated charcoal, a charcoal transfer pipe that transports the sucked-up charcoal, a cyclone separator that separates the charcoal and air transported from the charcoal transfer pipe in a mixed state, and a charcoal intake container that takes in the charcoal from the cyclone separator. In the charcoal production system of the present invention, low-temperature outside air acts on the charcoal transfer pipe connecting the charcoal storage container and the charcoal intake container, so that the mixed charcoal being transported in the charcoal transfer pipe can be cooled. (4) Charcoal production management system

[0055] (Microcontroller B) The charcoal production management system according to the present invention is equipped with various measuring instruments that measure biochar production-related data, including at least firing temperature, amount of charcoal material supplied, amount of charcoal produced, firing time, and charcoal production location, on the mobile charcoal production apparatus, and a microcomputer B that can receive the biochar production-related data from these various measuring instruments. Therefore, the microcomputer B, which is equipped with a transceiver and memory, can receive the biochar production-related data measured by the various measuring instruments of the mobile charcoal production apparatus via the transceiver and store it in its memory.

[0056] (Communication network) The present invention relates to a biochar production management system in which a microcontroller B, a management server A, and a device C registered with and accessible by the management server A are connected via a communication network. The microcontroller B registered with the management server A transmits biochar production-related data to the management server A, which stores this data, and the device C registered with the management server A can access the management server A and view the biochar production-related data.

[0057] (Blockchain) Furthermore, in the charcoal production management system according to the present invention, the management server A can receive signed data from the microcontroller B, with message z being the hash value of the biochar production-related data. The management server A then verifies the authenticity of the signed data, and if its authenticity is confirmed, it records message z, i.e., the hash value of the biochar production-related data, on the public blockchain. Therefore, the charcoal production management system according to the present invention can prevent tampering with the biochar production-related data received from the registered charcoal production equipment.

However, the charcoal production apparatus 101 that constitutes the mobile charcoal production apparatus 1 according to the present invention may be a conventional charcoal production apparatus as shown in Figure 11, for example, and is not limited to the rotary kiln type charcoal production apparatus illustrated below. (2) Embodiment of a mobile charcoal production apparatus (2-1) Rotary kiln type mobile charcoal production apparatus

[0066] (Configuration of a mobile charcoal production device) As shown in Figures 1 to 5, the mobile charcoal production apparatus 1 according to this embodiment is as follows: (Component 1) A rotary kiln 110 burns rice husks 2 that are fed in from the connection part 110c side in the internal combustion chamber 113, and discharges the resulting charred coal 3 from the discharge part 110d. (Component 2) External combustion chamber 120 connected to the connection part 110c of the rotary kiln 110 The charcoal production apparatus 101, which includes the charcoal production apparatus, is fixed to the floor portion 11 of the fixed transport body 10 using fixing means, and the fixed transport body 10 to which the charcoal production apparatus 101 is fixed can be transported by the transport means 500 (see Figures 8 and 6(a) to (c)).

[0067] (Fixed transport vehicle) The fixed transport body 10 is a structure having a floor section 11, and in this embodiment it is either a container 10B (see Figures 1, 3, and 4) or a trailer 10A (see Figures 2 and 5).

[0068] (Rotating kiln mounting stand) The fixed transport body 10 fixes the external combustion chamber 120 of the charcoal production apparatus 101 to its floor 11, and also fixes a rotary kiln mounting stand 16 for installing the rotary kiln 110. As shown in Figure 3, the rotary kiln mounting stand 16 allows the rotary kiln 110 to be installed such that the connection part 110c of the rotary kiln 110 is connected to the external combustion chamber 120, and the rotary kiln 110 is tilted at a predetermined angle relative to the floor 11 from the connection part 110c toward the discharge part 110d.

(2-2) Configuration of the charcoal production apparatus

[0070] (Smoky charcoal manufacturing equipment) The charcoal production apparatus 101 according to the present invention includes (component 1) a rotary kiln 110 and (component 2) an external combustion chamber 120. (Component 1) A cylindrical hollow tube extending from the connection part 110c to the discharge part 110d, which is a rotary kiln 110 that burns rice husks 2 (charring material 2) fed in from the connection part 110c in the internal combustion chamber 113 and discharges the calcined charred 3 from the discharge part 110d. (Component 2) External combustion chamber 120 connected to the connection part 110c of the rotary kiln 110 and equipped with an exhaust means 122

[0071] Furthermore, the charcoal production apparatus 101 of the present invention is composed of the following (component 3) to (component 6). (Component 3) Air supply means 130 for supplying air into the rotating kiln 110 (Component 4) A charcoal material input pipe (charcoal material input means) 140 for introducing rice husks 2 into the rotating kiln 110. (Component 5) One or more rotating support members 114 that rotatably support the rotating kiln 110 and can be fixed to the floor of the fixed transport body. (Component 6) Rotary drive device 150 for rotating the rotary kiln 110 (2-2a) Regarding component 5 (rotating support)

[0072] (Component 5: Rotating support; roller) The charcoal production apparatus 101, comprising the above-mentioned (component 1) to (component 6), has a rotary kiln 110 fixed at a predetermined angle inclined with respect to the floor 11 of the fixed transport body 10, from the connection part 110c side into which the rice husks 2 are fed towards the discharge part 110d. The rotary support 114 that rotatably supports the rotary kiln 110 is, for example, one or more rollers 114 (see Figure 7(a)), and can be provided on a rotary kiln mounting base 16 fixed to the floor 11 of the fixed transport body 10.

[0073] (Partition plate, stirring plate, and internal combustion chamber) Furthermore, the inner surface of the rotating kiln 110 is equipped with one or more axial partition plates 112a, 112b (see Figure 7(a)) that partition the introduced rice husks 2 in the direction of its central axis 111c, and one or more stirring plates 111p that agitate the rice husks 2 in the direction of its rotation (see Figure 7(b)). The internal combustion chambers 113 (113a, 113b) are formed by being demarcated by these axial partition plates 112a, 112b, as shown in Figure 7(a). (2-2b) Regarding component 3 (air supply means)

[0074] (Component 3: Air supply means) As shown in Figure 7(a), the charcoal production apparatus 101 of the present invention is equipped with an air supply means 130 for introducing air into the rotary kiln 110. This air supply means 130 includes, for example, an air supply pipe 132 with many air holes inserted into the rotary kiln 110, and an air blower 134 connected thereto. The air blower 134 sends air into the internal combustion chambers 113a and 113b of the rotary kiln 110 via the air supply pipe 132 (see Figures 8 and 7(a)).

[0075] (Exhaust means) Furthermore, it is preferable to provide a chimney 122 as an exhaust means 122 in the external combustion chamber 120 connected to the connection part 110c side of the rotary kiln 110. When the internal combustion chamber 113 of the charcoal production apparatus 101 reaches a certain high temperature due to the combustion of rice husks 2, a flow of air is created from the chimney 122 provided in the external combustion chamber 120, drawing air in from inside the rotary kiln 110, reducing the pressure inside the rotary kiln 110, and drawing in outside air from the discharge part 110d side. As a result, a flow of air is created from the discharge part 110d side of the rotary kiln 110, passing through the inside of the rotary kiln 110 and being exhausted from the chimney 122 of the external combustion chamber 120, and this air can cool the charcoal 3 that has been burned. (2-2c) Regarding component 4 (means for inputting charcoal material)

[0076] (Component 4: Charcoal material input means) Furthermore, as shown in Figures 7 to 9, the charcoal material input means 140 is a charcoal material input pipe 140, with one end inserted into the internal combustion chamber 113 of the rotary kiln 110 and the other end connected to the automatic charcoal material supply machine 170. The charcoal material input pipe 140 supplies the charcoal material 2 supplied from the automatic charcoal material supply machine 170 by an air blower 174 to the internal combustion chamber 113 via a charcoal material transfer pipe (rice husk transfer pipe) 175. (2-2d) Regarding component 6 (rotary drive device)

[0077] (Component 6: Rotary drive device) Furthermore, as shown in Figure 9, the rotary drive device 150 includes an inverter 151 capable of modulating the voltage from the power supply 202, a motor 152 connected to the inverter 151, and an interlocking means 153 that interlocks the motor 152 with the rotary kiln 110, and the rotary kiln 110 rotates circumferentially in conjunction with the rotation of the motor 152 via the interlocking means 153.

[0078] Here, the interlocking means 153 may consist of a chain fixed in the circumferential direction of the rotating kiln 110 and a sprocket connected to the motor 152 and meshing with the chain. Alternatively, it may consist of a ring gear fixed in the circumferential direction of the rotating kiln 110 and a smooth wheel connected to the motor and meshing with the ring gear, and its configuration is not particularly limited.

[0079] Such a rotary drive device 150 can adjust the rotation speed of the rotary kiln 110, which is linked to the rotation of the motor 152, via the interlocking means 153 by adjusting the rotation speed of the motor 152 with the inverter 151. The charcoal production apparatus 101 according to the present invention can adjust the rotation speed of the rotary kiln 110, which is linked to the rotation of the motor 152, via the interlocking means 153 by adjusting the rotation speed of the motor 152 with the inverter 151. (2-3) Fixed transport body for rotary kiln type mobile charcoal production apparatus

[0080] Next, the fixed transport body 10 of the mobile charcoal production apparatus 1 of the present invention will be explained with reference to the diagram.

[0081] (Fixed transport vehicle) As described above, the fixed transport body 10 is a structure having a rectangular floor section 11, and is either a container 10B (see Figures 1, 3, and 4) or a trailer 10A (see Figures 2 and 5). These fixed transport bodies 10 can be moved together with the charcoal production device 101 by being housed in or connected to the means of transport 500 with the charcoal production device 101 fixed to the floor section 11.

[0082] As shown in Figure 3, or Figures 4 and 5, the external combustion chamber 120 of the charcoal production apparatus 101 is fixed to the floor 11 of the fixed transport body 10, and a rotary kiln mounting base 16 for installing the rotary kiln 110 of the charcoal production apparatus 101 is also fixed. Furthermore, as described above, the rotary kiln mounting base 16 allows the rotary kiln 110 to be installed such that the rotary kiln 110 connected to the external combustion chamber 120 is inclined at a predetermined angle relative to the floor 11 from its connection part 110c toward the discharge part 110d.

[0083] Thus, the mobile charcoal production apparatus 1 of the present invention has a rotating kiln 110 fixed to at least a rotating kiln mounting base 16 and an external combustion chamber 120 fixed above the floor 11, and allows rice husks 2 fed in from the connection part 110c of the rotating kiln 110 to be burned in the internal combustion chamber 113, and the resulting charcoal 3 to be discharged from its discharge part 110d. [Examples]

[0084] (trailer) In this embodiment, the fixed transport body 10 is a trailer 10A having a rectangular floor 11 with multiple wheels 42 below it, as shown in Figure 2. The trailer 10A may have a frame 13 that constitutes a container 10B loaded on top of the floor 11, or it may be fixed by welding, bolting, etc., but it is not necessarily required to load or fix the frame 13 (see Figure 5). The trailer 10A has a connector 40 at the front end of the floor 11, and with the charcoal production device 101 fixed to the floor 11, the connector 40 can be connected to a trailer head (transportation means 500) and moved. [Examples]

[0085] (container) In this embodiment, the fixed transport body 10 may be a container 10B in which a floor section 11 is formed on a rectangular frame 13, which is formed by connecting the four corners of a rectangular top frame 13u and a floor frame 13d, respectively, with column frames 13c, as shown in Figure 3. In Figure 3, the floor section 11 consists of a plurality of plate pieces that connect the opposing frame sides of the floor frame 13d.

[0086] As shown in Figure 1, the container 10B can be moved by loading the charcoal production device 101 onto the floor 11 and loading it onto a truck (means of transport) 500. Alternatively, as in Example 1, it can be loaded onto or fixed to the floor 11 of the trailer 10A, and the trailer 10A can be moved by connecting it to a trailer head (means of transport) 500.

[0087] As shown in Figure 6(a), container 10B may have a front panel 14f and a rear panel 14b, and left and right side panels 14l and 14r attached to the front, rear, left, and right sides of the frame 13, respectively. Alternatively, a top panel 14u and a floor panel 14d may be attached to the top frame 13u and floor frame 13d. It is desirable that the attached front panel 14f and rear panel 14b, and left and right side panels 14l and 14r be openable and closable.

[0088] Then, as shown in Figure 6(c), it is preferable to fix the charcoal production device 101 to the floor 11 or floorboard 14d, and to pass a chimney (exhaust means) 122, which extends above the external combustion chamber 120 of the charcoal production device 101, through a hole 15 provided in the attached top plate 14u. A mobile charcoal production device 1 with the charcoal production device 101 fixed to such a container 10B can be loaded onto a truck 500 and transported, as shown in Figure 6(b). (2-4) Smoky charcoal manufacturing method

[0089] (Smoky charcoal manufacturing method) The mobile charcoal production method according to the present invention is a method of producing charcoal by burning rice husks (charcoal material) 2 using a rotary kiln type charcoal production apparatus 101 as shown in Figures 1 to 5.

[0090] In the mobile charcoal production method according to this embodiment, the rotary kiln type charcoal production apparatus 101, as shown in Figure 7(a), has a chimney 122 extending above the external combustion chamber 120 as an exhaust means, a charcoal material input pipe (charcoal material input means) 140 fixed to the external combustion chamber 120 for inputting rice husks 2 into the connection part 110c of the rotary kiln 110 as a charcoal material input means, and an air supply means 130 consisting of an air blower 134 and an air supply pipe 132 with a plurality of air holes. The inner circumferential surface of the rotary kiln 110 is provided with hollow disc-shaped axial partition plates 112a and 112b as shown in Figure 7(a), and a stirring plate 111p as shown in Figure 7(b). Furthermore, the rotary kiln 110 is rotatably installed on top of a plurality of rollers 114 which are rotating supports (Figure 7(a)).

[0091] The mobile charcoal production method of this embodiment is a method for producing charcoal 3 by burning rice husks 2 using a charcoal production apparatus 101, as shown in Figure 4 or Figure 5, and involves sequentially performing the following steps: high temperature state formation step (S1), charcoal material input step (S2), mixed state combustion step (S3), combustion charcoal material accumulation step (S4), stirring step (S5), combustion completion step (S6), steaming step (S7), charcoal production step (S8), cooling step (S9), and charcoal discharge step (S10) (see Figure 8).

[0092] (High-temperature state formation step (S1)) The high-temperature state formation step (S1) is a step in which rice husks 2 are introduced into the rotating kiln 110 (internal combustion chamber 113), and the rice husks 2 are burned to form a high-temperature state inside the rotating kiln 110. In this step, first, rice husks 2 are introduced into the internal combustion chamber 113, kerosene or the like is sprayed on them and ignited to bring the inside of the internal combustion chamber 113 to a high-temperature state.

[0093] (Charcoal material input step (S2)) Step S2 involves introducing new rice husks 2 into the internal combustion chambers 113a and 113b, which are separated by axial partition plates 112a and 112b installed inside the rotary kiln 110, using a charcoal material introduction pipe (charcoal material introduction means) 140, as shown in Figure 7(a). At the same time, air is supplied using an air supply pipe 132 to mix the air with the rice husks 2. Since the rotary kiln 110 is configured to receive air with a sufficient oxygen concentration via the air supply pipe 132 and an air blower 134 (hereinafter referred to as the air supply means 130), the temperature of the smokeless combustion of the stacked rice husks 2 inside the rotary kiln 110 rises, and the generation of soot and toxic gases can be significantly reduced. Furthermore, this acts as a heat source, raising the firing temperature of the charcoal material and improving the efficiency of charcoal production.

[0094] (Mixed state combustion step (S3)) The mixed state combustion step (S3) is a step in which air and newly introduced rice husks 2 are burned in a scattered state in the internal combustion chambers 113a and 113b of the heated rotary kiln 110, and further burned in a mixed state including the burning rice husks 2 that were introduced in the high-temperature state formation step (S1). Since axial partition plates 112a and 112b are attached to the inner circumferential surface of the rotary kiln 110 to divide the rice husks 2 in the direction of their central axis, the combustion chambers inside the rotary kiln 110 can be divided into 113a and 113b. As a result, the thickness of the rice husk layer 2 can be maintained above a certain level, and the upper layer can block the air, maintaining the stability of the steaming state in the lower layer. This improves the efficiency of charcoal production and also makes it easier to adjust the burning time of the rice husks 2.

[0095] (Combustion char material accumulation step (S4)) The combustion charcoal material accumulation step (S4) is a step in which the rice husks 2, which are burned in a mixed state, are accumulated at the bottom of the rotary kiln 110.

[0096] (Agitation step (S5)) The stirring step (S5) is performed simultaneously with the combustion charcoal material accumulation step (S4) by rotating the rotary kiln 110, raising the burning rice husks 2 by stirring plates 111p provided on the inner surface of the rotary kiln 110, and then allowing them to free fall from a certain position to perform an upward and downward movement (see Figure 7(b)). In this embodiment, the mobile charcoal production 1 has multiple stirring plates 111p attached to the inner surface of the rotary kiln 110 to stir the rice husks 2 in the direction of its rotation. As a result, the upper layer of rice husks 2, which is burning at high temperature and smokeless, and the lower layer of rice husks 2, which is in a steaming state, can be easily and reliably replaced, eliminating uneven burning of the charcoal and ensuring uniform quality.

[0097] (Combustion termination step (S6)) The combustion termination step (S6) is the step in which the burning rice husks 2 cease combustion while moving up and down.

[0098] (Steaming step (S7)) In the steaming step (S7), the rice husks 2 move up and down while simultaneously blocking oxygen. As other rice husks 2 fall from above the burning rice husks 2, oxygen is blocked, resulting in a steaming process.

[0099] (Charcoal production step (S8)) The charcoal production step (S8) is a step in which charcoal 3 is produced by performing steps (S6) and (S7) in succession.

[0100] (Cooling step (S9)) The cooling step (S9) is performed simultaneously with the charcoal production step (S8) and utilizes the airflow generated by the chimney 122 to cool the charcoal 3 immediately after its production.

[0101] (Charcoal discharge step (S10)) The charcoal discharge step (S10) is the step of discharging the cooled charcoal 3 immediately after production from the discharge section 110d of the rotary kiln 110. In this embodiment, the mobile charcoal production system 1 is set up so that the rotary kiln 110 is tilted at a predetermined angle relative to the floor section 11 of the fixed transport body 10, from the connection section 110c toward the discharge section 110d. As a result, the rice husks 2 are automatically pushed toward the discharge section 110d while being burned and can be accumulated in the charcoal storage container 180 placed below the discharge section 110d. (3) Charcoal production system

[0102] Hereinafter, the charcoal production system 100 according to the present invention will be described in the following Embodiment 3 with reference to Figure 8, with the fixed transport body 10 constituting the mobile charcoal production apparatus 1 being a container 10B and the charcoal production apparatus 101 being a kiln-type charcoal production apparatus 101. In Figure 8, the container 10B is movable with wheels, but it is preferable to lock the wheels when producing charcoal. In this embodiment as well, the charcoal material 2 is rice husks 2. [Examples]

[0103] (Transportation of charcoal materials) The charcoal production system 100 according to this embodiment includes a mobile charcoal production device 1 on which a charcoal production device 101 is installed, a rice husk moving device 162 for moving rice husks 2 from a charcoal material container 160, and a hopper (charcoal material input container) 164 into which the rice husks 2 moved from the rice husk moving device 162 are fed. The charcoal production system 100 also includes an automatic rice husk feeder (automatic charcoal material feeder) 170 for supplying the rice husks 2 fed into the hopper 164 into the charcoal production device 101 via a charcoal material transfer pipe 175 after being mixed with air using an air blower 174. The charcoal material container 160 is not particularly limited, and may be a container for rice husks, for example, that is provided at a farm or other location where the mobile charcoal production device 1 is transported, or the rice husks 2 may be moved directly from a rice husk storage area without using a container. Furthermore, a spring-type moving device (commonly known as a spring conveyor) 163 or the like can be used for the rice husk moving device 162.

[0104] (Manufacturing of smoked charcoal) As described above, the charcoal production apparatus 101 is equipped with an air supply pipe 132 (air supply means 130) that uses an air blower 134 to supply air over a wide area into the external combustion chamber 120 and the rotary kiln 110 of the charcoal production apparatus 101, and produces charcoal 3 by mixing air with the charcoal material 2 supplied into the rotary kiln 110 from the rice husk automatic feeder (charcoal material automatic feeder) 170 via the charcoal material input pipe (charcoal material input means) 140.

[0105] Furthermore, the charcoal production system 100 of this embodiment includes a charcoal storage container 180 positioned below the discharge section 110d of the rotary kiln 110 to accumulate the charcoal 3 discharged from the discharge section 110d. The charcoal storage container 180 is not particularly limited and may be procured locally from a farm or other location at the destination.

[0106] (Transportation of charcoal) The charcoal production system 100 of this embodiment includes a charcoal suction device 182 that sucks up the charcoal 3 accumulated in the charcoal storage container 180, a charcoal transfer pipe 184 that transfers the charcoal 3 sucked into the charcoal suction device 182, a cyclone separator 186 that transfers the charcoal 3 in a mixed state from the charcoal transfer pipe 184 and separates the charcoal 3 in this mixed state from the air, and a flexible container (charcoal intake container) 188 that takes in the charcoal 3 in the cyclone separator 186.

[0107] (Operation of the charcoal production system) Next, the operation of the charcoal production system 100 according to this embodiment will be described. First, the rice husks 2 in the charcoal material container 160 are inserted into the automatic rice husk feeder 170 by a spring conveyor (spring-type moving device) 163. The rice husks 2 inserted into this automatic rice husk feeder (automatic charcoal material feeder) 170 are mixed with air by the air blower 174 of the automatic rice husk feeder 170 and supplied to the external combustion chamber 120 and rotary kiln 110 of the charcoal production apparatus 101 via the rice husk transfer pipe (charcoal material transfer pipe) 175. At the same time, air is supplied over a wide area into the external combustion chamber 120 and rotary kiln 110 from the air blower 134 via the air supply pipe 132, and the rice husks 2 are burned in these charcoal production apparatus 1 to produce charcoal 3.

[0108] The calcined charcoal 3 is pushed out from the discharge section 110d of the rotary kiln 110 and accumulated in the charcoal storage tank 180 located below it. The charcoal 3 accumulated in this charcoal storage tank 180 is sucked up by the charcoal suction device 182 and transferred to the cyclone separator 186 via the charcoal transfer pipe 184, in a mixture with air. In the cyclone separator 186, the air is discharged from the exhaust port at the top due to the cyclone effect, and the charcoal 3 falls and is stored in the flexible container 188.

[0109] In conventional charcoal production equipment, once the calcined charcoal is deposited in the charcoal tank, it needs to be cooled. In contrast, the rotary kiln type charcoal production system 100 of this embodiment transfers the calcined charcoal 3 from the charcoal storage tank 180 to the cyclone separator 186 and then to the flexible container (charcoal intake container) 188 via the charcoal transfer pipe 184. As a result, low-temperature outside air acts on the charcoal transfer pipe 184, allowing the mixed charcoal 3 to be cooled during transfer. The charcoal intake container 188 is not limited to a flexible container, and any container, bag, etc., made of appropriate material and shape can be used. (4) Charcoal production management system

[0110] (General charcoal production management system) As shown in Figure 9, the charcoal production management system 200 according to the present invention is a management system for the charcoal production process, in which various measuring instruments 210 that measure biochar production-related data, including at least firing temperature, amount of charcoal material supplied, amount of charcoal produced, firing time, and charcoal production location, are installed on a mobile charcoal production apparatus 1, and a microcomputer B connected to the various measuring instruments 210 by wire or wireless means and capable of receiving each of the biochar production-related data from the various measuring instruments 210 is installed.

[0111] Therefore, the various measuring instruments 210 include a temperature measuring instrument 213, a supply amount measuring instrument 214, a production amount measuring instrument 215, a clock 212, and a GPS 211. These various measuring instruments 210 are preferably kept permanently in the mobile charcoal production apparatus 1 or the charcoal production apparatus 101, but may also be added to the charcoal production system 100 at the destination of transport of the mobile charcoal production apparatus 1. Furthermore, among the various measuring instruments 210, small devices such as the GPS 211 can be housed in the control panel 201 together with the microcomputer B. (4-1) Measurement of biochar production-related data (4-1a) Measurement of charcoal production volume, firing time, and charcoal production location

[0112] (Amount of charcoal produced, firing time, location of charcoal production) As shown in Figure 9, the charcoal production management system 200 of the present invention includes a GPS 211, which allows the location of the mobile charcoal production device 1 to be confirmed, and therefore the charcoal production location to be measured. In addition, a clock 212 is usually provided with the GPS 211, and the charcoal production management system 200 can measure the firing time of the charcoal production device 101 (mobile charcoal production device 1). Furthermore, the charcoal production management system 200 can measure the amount of charcoal produced by, for example, equipping the charcoal intake container (flexible container) 188 shown in Figure 8 with a weighing scale (production amount measuring device) 215. (4-1b) Measurement of the amount of charcoal material supplied

[0113] (Charcoal material supply amount) Furthermore, in the charcoal production management system 200 according to the present invention, the amount of charcoal material supplied is measured, for example, using the automatic charcoal material supply machine 170 as shown in the following Example 4. [Examples]

[0114] (Configuration of the automatic charcoal material feeder) As shown in Figure 9, the automatic charcoal material feeder 170 includes an inverter 171 capable of modulating the voltage from the power supply 202, a motor 172 connected to the power supply 202 via the inverter 171, a screw 173 connected to the motor 172 for transporting the charcoal material, and an air blower 174 that supplies the charcoal material 2 transported by the screw 173 to the charcoal manufacturing apparatus 101 via a charcoal material input means (charcoal material input pipe) 140 (see Figures 5 and 8).

[0115] The automatic charcoal material feeder 170 transports the charcoal material that descends from the hopper (charcoal material input container) 164 toward the air blower 174 using a screw 173 (see Figure 5).

[0116] (supply amount measuring device) Therefore, the supply amount measuring device 214 can calculate the amount of charcoal material 2 transported per unit of time by the rotational speed of the screw 173 (motor 172) adjusted by the inverter 171, and determine the amount of charcoal material supplied (see Figure 9). (4-1c) Measurement of firing temperature

Example 5 describes the measurement of the firing temperature in the kiln-type charcoal production apparatus 101. [Examples]

[0118] (Firing temperature) In the kiln-type charcoal production apparatus 101, the firing temperature can be measured using, for example, a thermocouple 213. That is, in the charcoal production management system 200 according to the present invention, the temperature measuring instrument 213 can be measured by attaching the thermocouple 213 to the tip of the charcoal material input means (charcoal material input pipe) 140 inserted into the internal combustion chamber 113 of the kiln-type charcoal production apparatus 101, as shown in Figure 9, for example, to measure the temperature inside the internal combustion chamber 113. (4-2) Communication Networks

[0119] The charcoal production management system 200 according to the present invention, as shown in Figure 10 for example, is a charcoal production management system 200 in which a management server A having a database and managing a mobile charcoal production apparatus 1 and related biochar production data, a microcontroller B having a transceiver B3 and memory B4 and being able to receive biochar production related data measured by various measuring instruments 210 of the mobile charcoal production apparatus 1 via the transceiver B3 and store it in memory B4, and a device C that is registered with and accessible by the management server A are connected via a communication network 300. In Figure 10, the central processing unit (CPU) of the microcontroller B is explicitly shown as CPUB1. The communication network 300 may be the Internet 300.

[0120] The biochar production management system 200 works as follows: the microcontroller B of the mobile biochar production device 1, whose MAC address is registered with the management server A, transmits biochar production-related data received from various measuring instruments 210 of the mobile biochar production device 1 to the management server A via its transceiver B3. The management server A can then store the biochar production-related data received from the microcontroller B in its database. Furthermore, a device C registered with the management server A can access the management server A and view the biochar production-related data stored in its database if certain conditions are met. (4-3) Blockchain

[0121] As described above, the charcoal production management system 200 can store biochar production-related data received from the microcontroller B in the database of the management server A. Furthermore, the charcoal production management system 200 according to the present invention can guarantee the authenticity of the biochar production-related data by recording the hash value of this biochar production-related data on the public blockchain 310. The configuration of the charcoal production management system 200 according to the present invention that utilizes the public blockchain 310 and the method of recording biochar production-related data on the public blockchain 310 will be described below with reference to Figure 10.

[0122] (Private key, public key, and ID address) The charcoal production management system 200 according to the present invention includes a microcontroller B of a mobile charcoal production apparatus 1 equipped with a secure element B2, which can generate a random secret key and store it in the secure element B2. The microcontroller B generates a public key from the secret key using a predetermined program and hashes it using a predetermined hash function. Then, it generates an ID address from this hashed public key according to a predetermined rule and records and registers it in the database of the management server A along with the MAC address of the microcontroller B.

[0123] Here, the specified program is, for example, secp256k1, and the specified hash function is, for example, Keccak256. The specified rule for generating the ID address is, for example, an Ethereum-style rule that prefixes the last 20 bytes of the hash value of the public key with 0x.

[0124] (Message Z, signature) Next, microcontroller B hashs the biochar production-related data received from the various measuring instruments 210 of the mobile charcoal production device 1 and stored in its memory B4 to generate message z. Then, using the public key generated from the private key, it generates a signature for message z in a predetermined signature format and sends the signed data consisting of this signature and the generated message z to management server A. The predetermined signature format is, for example, the Ethereum signature format.

[0125] (Verification of signature data) In this manner, the management server A, which receives signature data from the microcontroller B of the mobile charcoal production device 1, recovers the public key from the received signature data in the predetermined signature format and hashes it using the predetermined hash function. Then, it can generate a verification ID address from this hashed public key according to the predetermined rules.

[0126] Management server A compares this verification ID address with the ID address of microcontroller B, which is recorded and registered in its database along with the MAC address, to check if they match. If they match, it can be confirmed that the signature data received from microcontroller B of the mobile charcoal production device 1 was generated using the same public key that generated the previously registered ID address.

[0127] (Public blockchain) As described above, in the charcoal production management system 200 according to the present invention, the management server A compares the verification ID address received from the microcontroller B of the mobile charcoal production device 1 with the ID address of the microcontroller B, and if they match, records the signature data message z received from the microcontroller B on the public blockchain 310.

[0128] Furthermore, the present invention can be implemented in various forms with improvements, modifications, and changes based on the knowledge of those skilled in the art, without departing from its spirit. [Industrial applicability]
