Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to organic processing in which raw materials containing organic fibers such as agricultural residues, food residues and organic waste produced in industrial production are processed by physicochemical reaction and biological or biochemical reaction. The present invention relates to a method and an apparatus for manufacturing a product .

[0002]

2. Description of the Related Art Agricultural residues, food residues, and organic waste produced by industrial production have been conventionally treated by incineration, landfill, marine dumping, etc., but these methods are preferable as they cause environmental pollution. Absent. The above-mentioned organic waste contains components such as nitrogen, carbohydrates, minerals, organic fibers, etc., but these components are organic processed products such as food materials, pharmaceutical materials, feed raw materials, industrial raw materials, and soil conditioners. In order to reuse it as a raw material or the like, it is necessary to convert it into physical properties and chemical compositions suitable for the purpose and to remove bacterial contamination such as pathogenic Escherichia coli, Salmonella, Cryptosporidium and the like. In order to convert nitrogen, carbohydrates, minerals, organic fiber, etc. in the ingredients into materials with balanced nutritional ingredients suitable for foods, feeds, etc., organisms that utilize useful microorganisms or biochemical reactions are suitable However, it is difficult to remove harmful microorganisms only by the antagonistic action between microorganisms.

With respect to the removal of harmful microorganisms, it is difficult to remove microbial contamination inside the organic waste because it is difficult to decompose solid matter such as fibers by using an ordinary antibacterial agent or pasteur sterilization. When heat sterilization is carried out by autoclave, dry heat sterilization, etc., useful components such as vitamins are often thermally decomposed due to high temperature.

[0004] Insoluble components such as fibers contained in organic waste can be utilized as nutrients having a tertiary function, but since waste is often woody, it has a bad texture and is a food material. It is difficult to obtain dietary fiber having physicochemical properties suitable for feed and the like by ordinary techniques.

The final residue of insoluble polymer such as aromatic polymer or fibrous polymer obtained by extracting useful components from organic waste is obtained by ordinary treatment in a high density state such as powder or pellets. Therefore, it is difficult to use for soil improvement etc. because the air permeability and water retention are low and the microorganisms in the soil do not easily grow. Therefore, chemical treatment with sodium sulfite or incineration is usually performed.

On the other hand, in order to recover the soil such as cultivated land, desertification zone, salt damage zone, pest-contaminated zone, etc. where surface soil has run away, and improve agricultural productivity, healthy soil microorganisms rich in organic matter are required. It is ideal to use the non-polluted soil inhabited by, but it is difficult to obtain a large amount of humus-rich good soil in the hardwood region, so it is difficult to remove soil such as clay and gravel. Often used. However, since these soils have a low content of organic matter, it is difficult for microorganisms to proliferate in the soil and has poor air permeability and water retention, and they are easily solidified by the treading of agricultural vehicles to form an impermeable layer. , The germination rate, root growth are poor, the soil ecosystem is simplified, and the resistance to harmful microorganisms is low, resulting in poor agricultural productivity.

When the same crop is cultivated for several years, pests such as nematodes, pathogenic bacteria, viruses and insects grow. Rotation and the use of pesticides are effective for preventing damages from these organisms, but pesticide-free or pesticide-reduction is required for the prevention of chemical damage, and the use thereof is difficult. In addition, major crops such as cabbage, Chinese cabbage, and broccoli belong to the same Brassicaceae family, which makes rotation difficult. Traditionally, stalks, leaves, roots, etc. of crops were incinerated, but it is difficult to incinerate because of environmental pollution.
There is a need for innovative techniques to remove pests.

[0008] Organic compost has been applied to improve soils that are poor in organic components, but it is difficult to stabilize the components, and nitrogen and excessive phosphoric acid are likely to fall. If the ripening is insufficient, microorganisms such as pathogenic Escherichia coli, Salmonella, and pathogenic parasites may grow and cause food poisoning or the like throughout the crop. As a method for preparing organic fertilizer, there is a compost prepared by naturally fermenting excrement of livestock and poultry, but it is difficult to ripen and adjust the components, and if the complete heat is insufficient, it decomposes after fertilization and ammonia, Hydrogen sulfide may be generated, damaging seedlings, and the balance of soil microorganisms may be lost, resulting in contamination with pathogenic microorganisms. In addition, the composting method, in which useful microorganisms such as actinomycetes, nitrogen-fixing bacteria, and filamentous fungi are allowed to act on the residue of foods, is simple, but as with compost, it is difficult to adjust the maturity and components, and pathogenic bacteria propagate. There is a risk.

In order to apply a biological reaction or a biochemical reaction to an organic material by utilizing microorganisms, enzymes, etc., a plurality of screws having fins of the same pitch inclined in opposite directions are arranged side by side in a reaction tank. A bioreactor has been proposed in which the contents of the reaction tank are sandwiched and rotated by rotating the screws in opposite directions to move vertically, vertically splitting the organic material, and performing the reaction while breaking and stirring. (Japanese Patent Laid-Open No. 8-228762). However, in this bioreactor, since the contents are moved in the same direction by using the screw with the same pitch, the fibrous tissue moves as it is, and there are cases where vertical tearing and breaking are difficult.

[0010]

The object of the present invention is to loosen, defibrate and break the fibrous tissue of an organic material, and to partially or shortly cut it biologically or biochemically. Therefore, it is possible to supply raw materials containing long organic fibers such as plants as they are to carry out physicochemical and biological or biochemical reactions, remove harmful microorganisms by these reactions, and have excellent nutritional balance. includes organics, and water retention, is to provide a manufacturing method and equipment of organic workpiece can be manufactured organic workpiece having air permeability.

In the present invention, the raw material for the reaction is a raw material containing an organic fiber, particularly a raw material containing a biodegradable organic fiber. Examples of the organic fiber include fibrous polymers such as cellulose, and fibrous organic substances such as aromatic polymerized polymers such as lignin. Examples of such raw materials include tissues such as plant stems, leaves, branches, roots, and shells; unused parts of food, food residues such as leftover food; organic waste such as disposable chopsticks, paper products, beet pulp, chips, etc. Can be given. These may be cut into short lengths for easy work, but may be left long. Further, it may be one in which pathogenic bacteria and pests are still attached. In addition to such a raw material containing an organic fiber, an organic raw material containing no organic fiber and an inorganic raw material can also be used as a reaction raw material.

The reactor for carrying out such a biological reaction of the raw materials may be any reactor as long as it forms a reaction chamber therein, but it is preferable that the tubular body is arranged in an inclined or horizontal state. The reactor is provided with a raw material supply section, a treated product extraction section, a gas extraction section, a drain, and the like. The raw material supply part and the gas extraction part are provided in the upper part of the reactor, the treated product extraction part is provided so as to communicate with the delivery part of the main screw, and the drain is provided in the lower part of the reactor. For these, a feeding or adjusting member such as a conveyor, a pump, a valve, or a stopping member is adopted according to the material to be transferred.

The reactor is preferably provided with a substance having voids for holding micro-organisms along the inner wall. The material having voids is preferably a porous material such as ceramics, but a material in which fibers are aggregated or a material in which nets are stacked can also be used. It is preferable that the voids or pores have a diameter of 2 to 10 mm and have continuous pores. Further, the reactor is preferably provided with a stirring device and a heating device in order to promote a biological or biochemical reaction, and a gas generated in the reactor may be used as an energy source in addition to a solar cell. The produced gas taken out from the gas take-out section has a gas refining device that removes vaporized components such as aroma components, hydrogen sulfide gas, etc., and recovers incombustible carbon dioxide as liquefied gas or dry ice, thereby reducing the energy value. It can be used for heating and gas power generation by increasing the concentration of high methane and hydrogen gas. In addition, the reactor is preferably provided with a medium supply means in order to efficiently carry out biological or biochemical reactions.

As the main screw, a plurality of screws are arranged side by side in the reactor so that the protrusions face each other, and the main screw is arranged so as to send out the object to be treated at different speeds. The delivery direction of the article to be treated may be the same direction or the opposite direction, but it is preferable to arrange the article to be delivered substantially in the direction of the article removal portion. Such a main screw may be arranged at any position in the reactor, but is preferably arranged along the lower surface of the reactor which is arranged in an inclined or horizontal state. If it is placed on a slant, the object to be treated is sent out obliquely upward of the reactor, and if a treated object take-out part is provided on the delivery side, the object to be treated that is settling up is scraped and ruptured to react. The defibrated and broken reaction product can be taken out as a treated product. Adjacent to the main screw, preferably when the reactor is gently tilted and when the reactor is installed horizontally and gravity does not cause convection of the object to be treated,
It is preferable to install an auxiliary screw in the space between the adjacent main screws to forcibly convect the contents to the opposite side of the treated product outlet.

By rotating the adjacent main screws having opposite spiral-shaped protrusions in opposite directions, the object to be processed can be sent out in the same direction.
In this case, it is preferable that the feeding speed can be changed by changing the shape, pitch and / or number of revolutions of the protrusions, whereby vertical tearing, breaking and stirring of the object to be processed can be performed with a simple mechanism. The main screw is not limited to one in which helical protrusions (fins) are continuous, and may have another shape such as a bevel gear having a groove stacked. If a combination of spur teeth and other stirring means are provided on the lower side of these main screws, it is possible to prevent the sedimentation of solid matter and to carry out the reaction. When the spiral-shaped protrusions of the adjacent main screws are in the same direction and rotate in opposite directions, the object to be processed is partially fed in the moving direction of each screw, but as a whole, It is sent out in a large direction. By installing an auxiliary screw that sends the object to be processed in the opposite direction between the main screws, the object to be settled can be efficiently convected.

When a sub-screw for feeding in the opposite direction is provided on the sending side of each main screw and a treated product take-out section is provided at both sending-out sections, microorganisms contained in the reaction solution are collected in the reaction chamber and useful microorganisms are provided at high density. Is preferable because the biological reaction can be continued while maintaining the temperature, and the object to be treated can be sent out from both sides and squeezed to extract the solid matter to be compressed. By providing a dehydration unit for dehydrating the processed product in the processed product extraction unit, the dehydrated processed product can be taken out. A combination of a screw conveyor and a cutter is preferable as the dehydrating section. If a dryer for drying the dehydrated processed product is provided, the dried solid organic processed product can be taken out. The product gas of the reactor can be used as the heat source of the dryer.

In the method for producing an organic processed product using the above apparatus, first, a raw material containing organic fiber is supplied from a raw material supply section to a reactor, a culture medium is supplied from a culture medium supply section if necessary, and a heating device is used to treat an object to be treated. Is heated and the main screw is driven to perform a biological or biochemical reaction. The biological or biochemical reaction performed here may be an aerobic reaction or an anaerobic reaction, but in general, a facultative or obligate anaerobic reaction is performed to digest organic matter containing fibers to obtain a useful organic processed product. It is possible because it is possible. In the apparatus, the digestion of cellulose-containing fibrous material increases with the shift to starvation culture accompanied by the reduction of easily digestible nutrients in the medium. In the case of aerobic reaction, a large amount of carbon dioxide gas is generated when the organic raw material disappears, but there is an advantage that the device can be downsized. Although organisms or microorganisms involved in biochemical reactions can proliferate spontaneously by continuing the reaction, they are collected from other reaction systems, the rumen of the cow, sheep, etc., the lower digestive tract, etc. and introduced with the medium. The reaction can be carried out.

In the biological or biochemical reaction in the reactor, the raw material is immersed in the reaction liquid (medium), the organic fiber and other solid matter are defibrated and broken by the main screw, stirred, and mixed with the microorganism. React in the state. The plurality of main screws arranged adjacent to each other feed the object to be treated containing the fibrous material at different speeds, but since the protruding portions are provided facing each other, defibration and breaking are performed at this portion. In this case, since the feeding speed of each main screw is different, the fiber material is stressed not only in the rotational direction but also in the axial direction, whereby the fiber material is loosened, and at the same time, the fiber material is longitudinally split and broken.

The defibrated and broken fibers are suspended in the reaction solution and are subjected to biological digestion. The object to be processed sent out by the main screw is taken out from the processed object taking-out part in a state in which the fibrous material has undergone defibration and breakage by the opposing protruding parts of the main screw rotating in opposite directions. At this time, if a sub-screw that sends out in the opposite direction is provided on the delivery side of the main screw, the objects to be processed sent out by the main and auxiliary screws are pressed against each other to be dehydrated, and the compressed solid processed object is taken out. The reaction solution in the reactor is taken out from the treated product take-out part or drain, and the bacterial cells, bacterial proteins and metabolites are separated by centrifugation or the like, industrial materials as organic processed products, food materials, It is used as a raw material for pharmaceuticals and feed.

The biota of the reactor varies depending on the raw material, medium, reaction conditions, etc., but in general, protozoa, cellulolytic bacteria, methanogens, fungi, or yeast are predominant. The organic raw materials are decomposed by these microorganisms, and pathogenic microorganisms and harmful insects attached to the organic raw materials are predated by these and rendered harmless.

Solid treated products produced by such biological reactions include low molecular weight organic substances produced by decomposition of sugars, lipids, proteins and the like in organic raw materials, microorganisms and metabolites thereof, and fibrous substances such as lignin and cellulose. It is a substance that consists of decomposition products that are broken down and broken. Since such an organic processed product contains an organic substance having an excellent nutritional balance with respect to human, animal or soil microorganisms and also contains a hydrolyzate of a polysaccharide such as cellulose, it has high water retention and air permeability.

Therefore, the above organic processed products are industrial raw materials,
It can be used as a food material, pharmaceutical material, feed material, and organic processed products containing a large amount of fiber such as lignin and cellulose can be used for soil improvement of agricultural land where surface soil has been washed away, desert areas, salt damage areas and other land. .

The treated product taken out of the reactor is sterilized by itself or in a dehydrated state, or by drying.
It can be used as an organic processed product in the dried state. Organic processed products containing a large amount of fibrous materials such as lignin and cellulose can be further mixed with earthworms, soil microorganisms such as rhizosphere microorganisms, fertilizer or soil to balance soil organisms and improve soil. It can be a suitable organic processed product.

In the lower part of 1 is a screw 3 driven by a motor 21b.
2, a dehydrator 35 including a cutter 33 and a perforated plate 34 is formed. Drains 36 and 37 are connected to the lower portion of the reactor 1 and the lower portion of the dehydrator 35, respectively.

A dryer 38 is provided adjacent to the dehydrator 35, and is constructed so that hot air is sent from a heating furnace 39 to dry and sterilize the solid processed material 40. 41 is a product take-out path, and 42 is an exhaust path.

A gas outlet 43 is connected to the upper part of the reactor 1, and the produced gas is a gas controller 44 and a gas purifier 4.
It is stored in the gas tank 46 via 5 and communicated so as to be sent to the heating furnace 39. Reference numeral 47 is a solar battery, which is connected to the storage battery 49 via the charge controller 48 so as to store electricity and supply power to the heater 5, the motors 21, 21a, 21b and the solenoid valve 27.

In the method for producing an organic processed product by the above-mentioned apparatus, first, the raw material 26 containing the organic fiber, which is put into the hopper 25, is fed from the raw material feeding section 22 to the reaction chamber 2 of the reactor 1 by the screw conveyor 24. Also, the medium supply unit 23
To open the solenoid valve 27 to supply the medium 29 and, if necessary, the microorganisms to the reaction chamber 2. These supplies are performed continuously or intermittently. On the other hand, power is supplied from the storage battery 49 to the heater 5 to heat the reactor 1, and the motor 21 is driven to rotate the main screws 6 and 7 to perform a biological reaction in an aerobic, facultative or obligate anaerobic state.

The shaft 13 is rotated by the rotation of the motor 21,
The rotational force is transmitted to the shaft 14 by the gears 19 and 20, and the shaft 1
3, 14 rotate in the opposite direction at a rotation speed of 3: 2. The main screws 6 and 7 are respectively helical protrusions 6a in the opposite directions,
7a, the main screw 6 is rotated by the arrow a due to the rotation.
Direction, the main screw 7 sends out the object to be treated in the direction of the arrow b and stirs the reaction liquid 3. The delivery speed of the object to be processed by the main screws 6 and 7 has a difference corresponding to the difference in the shape, rotation speed and pitch of these screws.

On the other hand, since the sub-screws 8 and 9 have the spiral projections 8a and 9a in the opposite directions to the main screws 6 and 7, the object to be processed is fed in the directions of arrows c and d. Also gear 1
1, 12 are protrusions 11a, 12a parallel to the axes 13, 14
Since it has a radial direction, the object to be processed is stirred so as to form a vortex flow around the shafts 13 and 14, and when solid matter in the object to be processed, particularly fiber material, passes between the gears 11 and 12, These are ground. As a result, the solid matter settled in the lower part of the reaction chamber 2 is scraped up, and a part thereof is defibrated and broken.

When the object to be treated is fed out by the rotation of the main screws 6 and 7, the fiber material moves while being caught in the projecting portions 6a and 7b, but the fiber material is defibrated because the feeding speeds of both are different, and The portions where the protrusions 6a and 7a face each other are broken by crushing together with defibration. This loosens the fiber quality and shortens the fiber. Such a tendency also appears due to one of the difference in the delivery speed due to only the difference in pitch or the difference in the delivery speed due to only the difference in the number of revolutions, but it becomes larger when the both are combined.

A part of the fibrous material and other solid matter broken by the main screws 6 and 7 is dispersed in the reaction liquid 3 by the stirring action of the main screws 6 and 7 and is digested by a biological or biochemical reaction. The fibers raised by the main screws 6 and 7 are also pushed back in the directions of arrows c and d by the auxiliary screws 8 and 9 to be dispersed in the reaction liquid 3 and undergo a biological or biochemical reaction.

Protozoa, bacteria, yeasts and the like grow in high density in the reaction solution, harmful microorganisms such as pathogenic bacteria and pests are predated and harmless, and digestion of plant tissues by protozoa and microorganisms occurs. Organic processed products with high water retention and air permeability are produced. In addition, the metabolites of the above microorganisms accumulate as useful substances.

A part of the solid matter sent upward by the main screws 6 and 7 is compressed and dewatered by sending out the auxiliary screws 8 and 9 in the opposite direction, and taken out from the processed product take-out section 31 as a processed product in a compressed state. . As for the reaction liquid, the increased amount is taken out to the processed product taking-out section 31 by overflow. The solid and liquid processed products taken out to the processed product take-out section 31 are further dehydrated by the dehydrator 35.

In the dehydrator 35, the solid matter is compressed and dehydrated by the rotation of the screw 32. The separated liquid is taken out from the drain 37 as a liquid treated product, and the bacterial cells, bacterial protein and metabolites are recovered as useful organic processed products by a separating means such as centrifugation. The solid matter squeezed by the screw 32 is cut by the cutter 33, extruded from the perforated plate 34, and enters the dryer 38.

The produced gas containing methane, hydrogen and carbon dioxide generated in the reaction chamber 2 is taken out from the gas taking-out passage 43 while the pressure is adjusted by the gas controller 44, the impurities are removed by the gas purifier 45 and stored in the gas tank 46. To do. The gas in the gas tank 46 is supplied to the heating furnace 39 for combustion, and hot air is sent to the dryer 38 to dry the solid processed material 40,

When a solid organic processed product is used as a raw material for a soil conditioner, microorganisms such as rhizosphere bacteria, earthworms and the like can be blended in the final step to obtain a final product.

The porous body 4 of the reaction chamber 2 is used to retain the microorganisms involved in the biological reaction, and when the microorganisms in the reaction solution decrease, the microorganisms retained here move to the reaction solution side. It migrates and proliferates. Further, even when the reaction liquid is discharged from the drain 36 for repair of the reactor 1 or the like, the microorganisms are retained, so that the microorganisms can grow after the reaction is restarted.

By slanting the cylindrical reactor 1 and the screws 6 and 7 as described above, the object to be treated can be efficiently delivered and stirred without depositing solid matter in the reaction chamber 2. It is possible to take out the processed material easily.
When adjusting the particle size of the solid processed product, a sieving means such as a screen may be provided above the processed product take-out section.

The reactor 1 may be heated mainly by the heat source of the generated gas. Further, the configurations of the screws 6, 7, 8, 9 and the like are not limited to those shown in the drawings, and can be changed. For example, a spiral miter gear having a shape in which spiral bevel gears are stacked, a paddle screw, a screw with a blade, or the like can be used. . Further, the raw material supply means, the processed material dehydration means, and the like may have other configurations.

According to the above apparatus and manufacturing method, a plurality of main screws for feeding the object to be treated at different speeds in substantially the same direction are arranged side by side so that the projecting portions face each other, and the organic fiber material is placed in the reactor. It is possible to loosen the fiber and longitudinally split it, as well as to cut it shortly because it is possible to perform the biological or biochemical reaction while defibrating and breaking the organic fiber with the main screw by supplying the raw material containing , Therefore, it is possible to directly feed raw materials containing long organic fibers such as plants to carry out physicochemical and biological or biochemical reactions, thereby removing harmful microorganisms and industrial raw materials, It is possible to produce an organic processed product that contains an organic matter having an excellent nutritional balance and has water retention and air permeability as a food material, a feed material, a soil conditioner, and the like.

FIG. 3 is a vertical sectional view showing an organic processed product manufacturing apparatus of another embodiment, and FIG. 4 is a BB sectional view thereof, and the same reference numerals as those in FIGS. 1 and 2 denote the same or corresponding portions.
The apparatus of FIGS. 3 and 4 has almost the same configuration as that of FIGS. 1 and 2, but since the main screws 6 and 7 have a spiral inclined in the same direction, the respective raw materials are reversed. A force for sending in the direction (arrows a, e) is applied. Further, in the above apparatus, the raw material is substantially sent out in the direction of arrow a due to the difference in the number of rotations and the pitch. An auxiliary screw 51 is provided adjacent to the lower side between the main screws 6 and 7 in parallel with the main screws 6 and 7, and is provided so as to send out the object to be processed in the direction opposite to the main screw 6. In this case, the auxiliary screw 51 has a spiral inclined in the same direction as the main screw 6, and the gear 53 attached to the end of the shaft 52 of the auxiliary screw 51 is

In the above apparatus, an organic processed product is manufactured in the same manner as in FIGS. 1 and 2, but the auxiliary screw 5 is used.
1 sends out the object to be processed in the direction opposite to the main screw 6 (direction of arrow c). As a result, the object to be settled on the lower surface of the reactor 1 moves downward in the reaction chamber, and the gear 11,
12 and 55, 56 are crushed, crushed and convected. Therefore, even if a large solid substance or a heavy solid substance is present, it is pulverized and circulated. The carbon dioxide in the gas discharged from the gas purifying device 45 is stored in the gas tank 46 and then liquefied by the carbon dioxide liquefying device 57.
The liquefied carbon dioxide is used by the dry ice production device 58 to produce dry ice. The obtained dry ice is used for destroying cells obtained as an organically processed product, sterilizing solid matter, and the like. A part of the generated gas is sent to the gas power generator 60, converted into electric energy, stored in the storage battery 49, and used as a power source for the motors 21, 21a, 21b and the like. The exhaust heat of the power generator may be used to heat the reactor 1. The liquid treatment products obtained from the drains 36 and 37 are sent to the compost tank 59, and the organisms such as earthworms, microorganisms and plants are propagated in the soil composed of porous ceramics. Propagated earthworms, microorganisms, plants, etc. are used as feed after being separated and collected from the soil using the difference in specific gravity and volume. A part of the plant is reused as a raw material.

FIG. 5 is a vertical sectional view showing an organic processed product manufacturing apparatus according to another embodiment. FIG. 6 is a sectional view taken along the line CC. The apparatus of FIGS. 5 and 6 is constructed much like that of FIGS. 3 and 4, but with the reactor 1 arranged horizontally.
Along with that, the screws 6, 7, 8, 9, 51, etc. are arranged horizontally, and the main screw 7 is the main screw 6
With opposite spiral and main screw 6
The difference is that the hook-shaped portion 6c is formed by the notch 6b in the spiral protrusion 6a. The arrangement of each component of the reactor 1 is almost the same as in FIGS. The treated product take-out part 31 has a height for holding the liquid surface of the reaction liquid 3 at a predetermined position, and the reactor 1 between the main screws 6 and 7 and the auxiliary screws 8 and 9.
Although it is open to the side surface and communicates with the dryer 38, the dehydrator 35 is not shown. The method for manufacturing an organic processed product by the above apparatus is performed in the same manner as in FIGS. 3 and 4. In this case, since the reactor 1 is arranged horizontally, it is easy to support and the apparatus is downsized, but the reaction itself can be performed with substantially the same efficiency as in the cases of FIGS.
