  If these organic wastes also have moving substances and plant matter and can be used as useful resources, there is an advantage that the amount of incineration and landfill can be reduced. The processing for recycling does not consume energy such as a heat source, and therefore, wet processing is preferable.

  From this point, the present invention is a fermentation which can liquefy animal and vegetable waste that has been discarded and incinerated so far by wet treatment, and can reuse organic waste to a useful form by wet treatment and fermentation. It is intended to provide a processing method. The present invention further provides a fermentation treatment apparatus that can wet-treat organic waste.

  In order to solve the above-mentioned problems, the present invention further includes a step of crushing a raw material organic material, which is a moving substance or plant waste, with a crusher, and a slurry containing the crushed organic material crushed with a crusher in an annular flow to further crush the organic material An organic substance is fermented, including a step of atomizing and a step of fermenting the atomized slurry. Thereby, organic waste can be taken out from the slurry which refined | miniaturized organic matter as a fermented liquid, and can be supplied for a useful use.

  The organic matter fermentation treatment method preferably includes a step of adding a fermenting bacterium-containing base material to any one of the raw material organic matter, the crushed organic matter, and the slurry. In the process of processing these raw organic matter, crushed organic matter or slurry, the fermentation is advanced, the decay is prevented, the fermentation is promoted while the generation of malodor is suppressed, and finally the slurry is supplied as a fermentation liquid It is to be fermented. In the fermentation process, the solid organic matter can be made substantially liquid by storing the slurry from the atomization apparatus in the fermenter and fermenting the atomized organic matter in the fermenter.

  Since the fermented liquid contains a fertilizer component and an organic component necessary for plant growth, it can be used as a liquid fertilizer and as a soil conditioner for agricultural land.

The present invention further includes equipment suitable for the organic matter processing method. The equipment comprises a crusher for crushing the organic material of the moving material or plant material, and the crushed organic matter crushed by the crusher in a slurry. Comprising a micronizer for further atomizing the organic matter in an annular flow, and a fermenter for storing the slurry from the atomizer and fermenting the micronized organic matter,
The organic matter treatment facility preferably includes a fermenter addition device for spraying and adding the fermenter-containing substrate to any of the raw organic matter, the crushed organic matter, and the slurry.

  The organic matter processing method of the present invention treats moving substances or plant waste as raw organic matter, and these organic wastes are garbage from households, expired waste foods from grocery stores, restaurants, etc. Waste food, seafood residues after processing and cooking from food processing plants, and compressed residues from fermented food manufacturing processes such as beans, rice, and potatoes, etc. and so on.

  These wastes contain moving substances or moving substances, which are first crushed as raw organic substances to an appropriate size. In this crushing step, the organic matter is finely pulverized, chopped, or ground by a crusher. As an example of the pulverizer, a rotary hammer crusher described later can be used.

  The waste to be sent to this crushing step may be in a dry state depending on the waste acceptance mode, but is usually wet or wet. In this case, the crushed organic matter contains water. In a slurry form.

  Between the crushing step and the atomization step, a step of separating a coarse product from the crushed organic matter may be provided, and it is usually preferable to pass through a vibrating screen having an appropriate mesh. By removing coarse objects that could not be crushed in the crushing step, the burden of atomization operation in the atomizer can be reduced, or troubles such as clogging can be avoided.

In the next step, the crushed organic matter crushed by the crusher in the crushing step is held in a slurry state and atomized. In this step, the present invention is to further atomize the crushed organic matter by flowing a slurry containing the crushed organic matter in a ring at a high speed.

  The atomization step is intended to further refine the particles in the crushed organic matter slurry in order to promote fermentation in the fermentation step described later. In this step, pressure is applied by a pump and discharged into an annular flow path between an inner cylinder and an outer cylinder arranged approximately coaxially through a nozzle to form a high-speed flow of slurry in the annular flow path. A method is used in which the organic particles contained in are refined by high-speed flow.

  This annular flow is made very fast, thereby further atomizing the organic particles using the impact force of the slurry flow, the shear force, or the breaking force caused by bubbles. The circulation flow rate is preferably 8 m / s or more, and preferably in the range of 10 to 30 m / s.

  Since the atomization step uses the flow rate of the slurry, it is preferable to prepare the crushed organic matter in the form of a slurry before feeding into this step. If the raw organic material is originally wet or wet, the ground organic material is a slurry. Further, it is preferable to add an appropriate amount of water so that the concentration is appropriate so that it can be supplied to the annular flow path through the nozzle.

  In this refining step, it is preferable that an organic substance having a particle size of about 1 to 30 mm on the inlet side can be reduced to a size of 100 μm or less, particularly about 10 to 0.1 μm from the outlet side. This atomization step has the advantage that the organic matter contained can be refined in the state of the slurry, and the atomized slurry can be further post-treated in a liquid state.

  A preferred embodiment includes the step of adding the fermenting bacterium-containing base material to any one of the raw organic material, the crushed organic material, and the slurry in the above method. In this step, the organic matter is added together with the fermentation base material, and fermented bacteria are included, so that the organic matter is sequentially fermented in the above-described crushing and atomization processing steps or in the fermentation step described later to obtain solid organic matter. Is preferably less, preferably finally extinguished. It is convenient to add the fermentation base material at an early stage of a series of treatment steps in order to prevent the generation of a strange odor due to decay and the attraction of harmful insects such as flies during the treatment. The fermenting bacteria-containing substrate may be added to the raw material organic material before crushing, which is preferable in that the fermentation proceeds in the subsequent crushing step and atomization step.

  The fermentative bacteria used here are selected from fungi that have the ability to efficiently decompose without causing off-flavors and toxic substances against the moving substances and plant-based organic substances resulting from the above-mentioned organic waste. Examples of fungi that can be used include lactic acid bacteria, actinomycetes, acetic acid bacteria, and yeasts. These fungi are added together with the base material for culturing, either in the raw material organic matter, the crushed organic matter, or the atomized slurry, or in two or more stages, but finally in the atomized slurry in the fermentation process. The finely divided organic particles having a very small size are decomposed directly or indirectly in a short time to eliminate organic solids.

  For this reason, in this fermentation process, since the slurry which came out of the atomization apparatus already contains fermentation bacteria in the fermentation process, the slurry is stored in a fermenter to ferment the atomized organic matter. The slurry containing the finely divided organic substance is sequentially retained in the fermentation sent to the fermenter to advance biochemical decomposition of the organic fine particles by the fermenting bacteria.

  In this fermentation process, the fermenter may be a vertical cylindrical tank or a horizontal tank, and by connecting a plurality of tanks by piping in two or two stages in series or in parallel, the residence time can be secured. It is preferable in terms of ensuring separation. At the final stage of fermentation in the fermenter, the supernatant liquid in the fermenter is almost completely lost of organic solids, forms a translucent aqueous solution, hardly feels a strange odor, and dissolves in water. An issuing solution containing organic components and bacteria is obtained.

  In the organic matter fermentation treatment facility of the present invention, a crusher is used for crushing moving materials or plant-based raw organic materials. In the atomization apparatus, the crushed organic matter crushed by a crusher is made into a slurry, and the organic matter in the slurry is further atomized in an annular water flow, and the atomized slurry is then fermented in a fermenter.

  The crusher is a crusher for roughly crushing organic waste to prepare particles having an appropriate size, and a mechanical crusher can be usually used. Since the material to be crushed is waste from animals and plants, a rotary hammer type crusher can be preferably used as the crusher. One example of a hammer crusher is a substantially cylindrical casing having an entrance at the top and an exit at the bottom, and a pivoting support with one end supported around a drive rotation shaft supported along the axis inside the casing. A hammer rotating body including a plurality of hammers provided, and a fixed blade that projects from the inside of the casing and crushes the object to be crushed in a cooperative relationship with the hammer. A rotary hammer type crusher uses a rotary hammer and a fixed blade to break and cut flexible meat, crush hard bone tissue such as fish bones and animal bones with a hammer, and long fibers such as rice straw and fiber The quality can be easily cut into pieces and made fine.

In the present invention, the atomization device is characterized in that the crushed organic matter crushed by the crusher in the crushing step is held in a slurry state and further atomized in an annular water flow.

  A preferable example of the atomization apparatus is a cylindrical container composed of an inner cylinder and an outer cylinder arranged substantially coaxially, and an annular flow path between the inner cylinder and the outer cylinder, and slurry to the annular flow path. The slurry discharge device has a discharge nozzle fixed to an outer cylinder and a pump connected to the slurry discharge device. The slurry of the crushed organic matter is circulated in an annular flow path to atomize organic particles.

  Further, as the atomization device, a device in which devices having the same annular flow path are arranged in series in two to three or more stages can be used. In the above example, the multistage atomization apparatus further includes a second outer cylinder outside the outer cylinder, and the second annular channel is formed between the outer cylinder and the second outer cylinder. A second pump for pressurizing the slurry discharged from the annular flow path, and a second slurry discharge device including a nozzle fixed to the second outer cylinder so as to discharge the second annular flow path, A slurry in which the slurry from the second pump is circulated through the second annular channel to refine the organic particles can be employed.

  The slurry atomized by the atomizer is held in a fermenter, for example, a suitable fixed container or moving container, and fermented with fermenting bacteria to reduce or eliminate organic solids. Usually, fermentation period can be set and fermentation conditions can be set to promote fermentation.

  Furthermore, the raw material organic matter, the crushed organic matter, or the atomized slurry includes a fermenting bacterium adding means for spraying and adding the fermenting bacterium-containing base material to any of them. Usually, in order to add as a liquid containing fermenting bacteria, it can be directly added or sprayed into the raw organic material, the crushed organic material, or the atomized slurry using a spray equipped with appropriate piping.

  In the present invention, the fermenting bacterium-containing substrate may be selected from available fungi and liquefied and added, but preferably, it may include a fermentation bacterium culture step for preparing the fermenting bacterium-containing substrate. In this step, the fermenting bacteria are cultured under predetermined culture conditions, and the fermenting bacteria-containing substrate is added to any one of the raw organic material, the crushed organic material, and the slurry in the step of adding the fermentation bacteria. In this case, the fermenting fungus may collect the soil or the native plant in the vicinity of the facility and cultivate the fungus attached to the soil or the plant.

  In the fermenting bacterium adding means, preferably, a spray nozzle is used, and the slurry containing the fermenting bacterium is formed into a water droplet or spray, and sprayed and mixed on the raw material organic matter, crushed organic matter or atomized slurry. For fermentation bacteria culture, it is preferable to prepare the fermentation bacteria-containing substrate, including a fermentation bacteria culture apparatus. The culture apparatus of the addition means includes a culture tank, and in the culture tank, the fermented bacterial strain is added to the culture solution and grown under culture conditions. Thus, it is added to the raw material organic matter, crushed organic matter or atomized slurry.

  Furthermore, the culture apparatus preferably includes a separate atomization apparatus for culturing, and the atomization apparatus for culture creates a high-speed water stream that flows in an annular shape by the water discharged from the nozzle, and an appropriate culture medium is formed in this annular high-speed water stream Preferably, a slurry containing animal and plant organic matter particles suitable for the above is added, and finely divided into fine particles of 10 μm or less, preferably using the impact force and shear force of the water flow. The organic slurry containing the refined particles is transferred to a culture tank, and the fermented bacterial strain obtained from the slurry in the tank or the collected soil and plant tissue are added to grow. The slurry containing the fermenting bacteria is added to the raw material organic matter, the crushed organic matter or the atomized slurry in the same manner as described above as the fermenting fungus-containing substrate.

  On the other hand, the fermented liquor obtained from the fermenter by the treatment facility of the above embodiment contains nitrogen, phosphorus, potassium and other fertilizer components important for plant cultivation in the liquor. Thus, it can be used as a liquid fertilizer. The liquid contains a large amount of fermenting bacteria and can be applied to the soil to improve the soil, which has a favorable effect on the growth of the crop.

  Moreover, in the field of livestock farmers, the fermented liquor may be supplied by being sprayed on the floor as a fermenting fungus that ferments the wooden chips in livestock such as pigs that use wooden chips as a flooring material. It is possible to ferment the flooring with urine and prevent its off-flavor and improve the breeding environment. Furthermore, a part of the crushed organic matter from the crusher can be used as a main useful feed, and can also be used for raising livestock, particularly pigs.

  In such a fermented liquid, a large amount of fermenting bacteria are present, so that a part of the liquid is contained in any one of the raw material organic material, the crushed organic material, or the atomized slurry in the above crushing step or atomization step. It can also be added as a base material, whereby fermenting bacteria can be circulated and used.

  FIG. 1 shows a system diagram of a processing facility according to an embodiment of the present invention. The waste to be processed here is a waste of food or a processing residue of food processing. Foods 1a sealed and stored in containers, for example, milk in containers, expired foods, and other unwrapped packaged foods, etc., are put on a packaging crusher 22 by a hopper 21 and a screw conveyor 211 that conveys the packaged foods. The waste 11a is sent to the next sorter 24 together with the container fragments from the crusher 22 for solving the problem.

  In this embodiment, the sorter 24 further includes food waste that has not been packaged or removed, and waste 1b that can be easily separated by other simple packaging, by a hopper 23 and a screw conveyor 231. The waste material 11a is sent to the crusher 4 as the raw material organic material 11 after the fragments such as the packaging material, the plastic container, and the metal are separated.

  Further, unprocessed waste, for example, food processing residue 1c including bone cut from an edible portion at a food processing plant or the like, is also input into the crusher 4 as the raw material organic material 11.

  The crusher 4 crushes to the size of a solid necessary for processing in the subsequent atomization step. Usually, the size of the organic material is reduced to 30 mm or less, particularly preferably 10 mm or less. As will be described later, this example uses a vertical hammer turning type crusher, and the raw material organic material 11 charged from above is finely crushed by a hammer piece turning inside the container, To fall as crushed organic matter 12. The crushed organic matter 12 is held in a suitable slurry tank 28. In the example of FIG. 1, the second sorter 27 for removing unsuitable matters such as coarse substances and metal pieces from the crushed organic matter 12 is used. And the sorted crushed organic matter 13 is supplied to the slurry tank 28 by a screw conveyor. As the sorter 27, a wet sieve device can be used.

  As described above, the crushed organic matter 13 crushed and sorted by the crusher 4 has fluidity when the raw material waste 11 is in a wet state with some or sometimes a large amount of moisture. Obtained in a slurry state. However, water is appropriately added to the slurry tank 28 to adjust the slurry concentration and fluidity, and the fluidity necessary for the subsequent atomization step is adjusted.

  The slurry tank 28 is provided with a stirrer 281 of a stirring device 282 so as to stir the slurry and keep the organic components in the slurry at a uniform concentration.

  The slurry tank 28 is connected to the atomization device 6, which will be described in detail later, and the organic solid content in the organic-containing slurry is further refined by the atomization device 6. As will be described in detail later, the atomization apparatus 6 generally discharges the above slurry through a nozzle into a circularly arranged flow path to create a high-speed water flow, which is fine by the impact force, shear force, and cavitation in the water flow. Then, the slurry is returned again to the slurry tank 28. Thus, the slurry circulates between the slurry tank 28 and the atomizer 6, and in this circulation step, the organic particles in the slurry are removed by the atomizer 6. Refinement gradually.

  2 and 3 show the atomization device 6, which is a bottomed, cylindrical container with a top plate 602 at the top, and is coaxially connected to the inner cylinder 61. A first annular flow path 64 is formed between the intermediate cylinder 62 disposed on the outer side, and a second annular flow path 66 is formed between the outermost outer cylinder 63 and the intermediate cylinder 62. . The upper end of the inner cylinder is opened to allow overflow near the top plate, and the first annular channel and the inner side of the inner cylinder 61 communicate with each other.

  With respect to the first annular flow path 64, a first injection pipe 71 including a first nozzle 72 at the tip is provided at the lower portion of the intermediate cylinder 62, and a discharge port 720 thereof is connected to the first first annular flow path 64. Is oriented along. A first pump 73 (in this example, a centrifugal pump) is connected to the rear of the injection pipe 71, and the inlet side of the pump 73 is connected to the slurry tank 28 through a pipe 70.

With respect to the second annular flow channel 66, a second injection pipe 76 including a second nozzle 77 at the tip is connected to the outlet of the second pump 78, and a discharge port 770 at the tip of the second nozzle 77 is connected to the second annular channel 66. Oriented along two annular channels 66. On the other hand, the inlet of the second pump 78 is connected to the lower bottom portion of the inner cylinder by a pipe 74. The second annular channel 66 is connected so as to return to the slurry tank 28 by a pipe 79 connected to a discharge port provided on the top plate.

During operation, the first pump 73 sucks the slurry 131 from the slurry tank 28 through the pipe 70, and the slurry is discharged from the discharge port 720 of the nozzle 72 to the first annular flow path 64. A high-speed water stream of slurry circulates in the annular flow path 64 between the intermediate cylinder 62 and the intermediate cylinder 62. The organic particles are further atomized by the impact force, shear force or cavitation in the circulating water stream. A part of the circulating water flow overflows from the upper end of the inner cylinder to the inside, and the slurry is sucked by the second pump 78 through the pipe 74 from the lower bottom thereof, and is discharged through the nozzle 77 of the second injection pipe 76. 770 is discharged into the second annular channel 66, and a high-speed water flow is formed in the second annular channel 66. In the second annular flow channel 66, the organic particles are further atomized and returned to the slurry tank 28 through the pipe 79.

  By continuing the circulation of the slurry between the slurry tank 28 and the atomizer, the average particle size of the organic matter in the slurry is gradually reduced.

  In this atomization step, when the organic particles are reduced to 100 μm or less, usually 10 μm or less, the slurry is transferred from the slurry tank 28 to the fermentation tank 30 by a pump 29 and piping. Since the organic particles have an average solid content size of 10 microns or less on average, they promote fermentation decomposition by fermenting bacteria in a later step.

  Fermentative bacteria can be blended in the raw material organic matter 11, the crushed organic matter 12, or the atomized slurry 14. In this embodiment, a spray 86 for spraying the fermenting bacteria-containing base material is appropriately provided. In this example, spray 86a is applied to the packaging crusher 22, spray 86b is applied to the sorter 24, spray 86c is applied to the crusher 4, or spray 86d is applied to the sorter 27, and spray 86e is further applied to the slurry tank 28. Has been placed. An aqueous solution containing each fermenting bacterium is added as droplets or spray. However, it is not necessary to provide all of these sprays. As the fermentation bacteria-containing base material, a fermented bacteria culture solution 84 cultured in a culture tank 82 of the culture apparatus 8 described later is supplied to the spray 86 as the fermentation bacteria-containing base material.

  The slurry containing the organic matter atomized by the atomization device 6, that is, the atomization slurry 14 is sent to the fermenter 30 via the pipe 140 and fermented for a predetermined number of days, and the organic particles are almost completely decomposed. In this example, the fermenter 30 uses a plurality of bowl-shaped containers, and the pump supplies the atomized slurry 14, stores the fermentation period, and discharges the fermentation liquid 15 according to the degree of fermentation.

  The fermentation layer 30 is a substantially confidential container, and a bowl-shaped cylindrical container whose upper mouth is closed by a movable lid is used. A plurality of fermenters 30 in this example are connected in parallel in this example, the supply timing of the atomized slurry 14 from the atomized slurry tank 28, and the discharge liquid The time lag between the fermentation maturity and the discharge and transport of the issued liquid 16 can be adjusted.

  Lactic acid bacteria, actinomycetes, yeast, etc. can be used as the fermenting bacteria used in this example. In this example, a structure is shown in which soil 87 containing fermented bacteria collected from soil is added to the culture tank 82, and the attached fungi are selectively cultured and used. The culture tank 82 is a bowl-shaped container equipped with a stirrer, and is supplied with a moving substance or vegetable organic matter 80 (for example, food waste) as a nutrient source. For the atomization, a separate atomization device 9 for culturing is provided, the organic matter 80 is atomized by the atomization device, the slurry 81 is fed into the culture tank 82, and the fermentation fungus soil 87 is added, Growing fermenting bacteria under specific culture conditions. In this case, the fermenting bacteria base material 83 containing the fermenting bacteria sufficiently grown in the culture tank 82 is a culture solution containing the above-mentioned finely divided organic matter supporting the fermenting bacteria. And is added to the pulverized organic matter 12 or the sorted crushed organic matter 13 such as the raw material organic matter 11 and food wastes 1a and 1b thereof from the nozzles 86a to 86e.

  On the other hand, the fermented liquid 16 from the fermenter 30 in the fermentation process described above contains fertilizer components and still active fermentative bacteria due to the decomposition of organic matter, and thus is used as a liquid fertilizer and as a soil conditioner by spraying it on cultivated soil. It can be used to grow cultivated plants.

  In the example of FIG. 1, a tank of a liquid transport truck 31 such as a tank truck or a vacuum car is filled from a fermenter 30 by an appropriate pipe 160 and is transported to a required farmland and sprayed.

  Further, the fermented liquid 16 can be applied to the livestock breeding field 33, for example, by spreading it on a breeding floor laid with wooden chips, thereby facilitating the fermentation of the wooden chips and effectively preventing the generation of off-flavors and attracting potatoes. There are advantages such as ease of maintenance of the health of domesticated livestock. Furthermore, although not shown, the crushed organic matter 12 and 13 crushed by the crusher 4 can be supplied as feed to the breeding ground 33 and used for feeding livestock, particularly pigs.

  In addition, the fermented liquid 16 is stored in a storage tank through an appropriate pipe, further fermented, and has a property of being highly transparent and sufficiently drained, so that it can be discharged into sewers and rivers. In the example shown in FIG. 1, a rotary type fermentation promoting storage tank 32, a horizontal storage tank 34, and a vertical storage tank 35 are shown. Fermentation liquid from the storage tank is discharged into the sewer or river.

  As for the above-described crusher 4 demonstrated in this embodiment, FIG. 5 shows a vertical rotary hammer crusher, which is driven in a cylindrical casing 40 that is generally opened up and down. A rotary crushing member fixed around the vertical shaft 50 is supported by upper and lower bearings 42 and 451, and has an inlet 421 at the upper part of the casing 40 and an outlet at the lower part. The rotary crushing member is rotationally driven by a motor M via an upper end portion. The rotary crushing member includes a vertical rotary shaft 50, and a rotary cutting blade 51 fixed around the upper side of the rotary shaft 50, and at the lower part thereof, a multi-layer rotary disk member fixed around the drive vertical shaft 50; It is composed of a large number of hammer pieces 54 arranged between the layers of the rotating disk member 53. The raw material organic material 11 supplied from the loading port 421 is crushed by the rotary cutting blade 51 and the rotary crushing member 54 while descending the casing, and is crushed organic matter through the space between the spokes 45 from below. It falls as 12 and is collected.

A plurality of shaft holes through which the shaft passes are formed at equal intervals in the circumferential direction. In many of these disks, the drive vertical shaft 50 is fitted into the center hole thereof, and the disks are fixed to the drive rotation shaft in a stacked state. An appropriate gap is formed between the peripheral edges of the stacked disks adjacent to each other, and a portion of the hammer piece is inserted into the gap so that the hammer support shaft 55 is connected to the hammer piece 54. The shaft hole 550 and each shaft hole of the large number of disks 53 are passed through and fixed at both ends with bolts. The hammer piece can be freely rotated around its axial hole, and the hammer piece 54 is arranged so that a part of the hammer piece 54 protrudes outward from the peripheral edge of the disk 53 with the rotation.

  Due to the rotation of the rotary disk member 53, the hammer piece is preferably provided with a shaft hole for the hammer support shaft at a position eccentric from the center of gravity of the hammer piece, and the hammer can be eccentrically rotated around the shaft hole.

  Corresponding to the hammer piece of the rotating disk member, a plurality of rod-shaped fixed blades that are long in the vertical direction are fixed on the inner peripheral surface of the cylindrical casing with appropriate intervals around the inner peripheral surface. The tip of the hammer piece extending from the disk member and the fixed blade are close to each other, and the organic particles are crushed therebetween.

  As an example of the hammer piece, in FIG. 6A, a rod-shaped hammer 542 having a substantially rectangular cross section is eccentric to one end side and the shaft hole 550 is measured. FIG. 6B shows a substantially circular hammer having an appropriate thickness, in which an unevenness 541 is formed on the peripheral end face, and a shaft hole 550 is provided at a position eccentric from the circular center. In either case, when the hammer support shaft 55 is inserted into the shaft hole 550 and fixed and rotated on the disk 53 of the rotating disk member, both the rod-shaped hammer and the circular hammer rotate eccentrically around the hammer support shaft 55, and a part of them. The rotating disk member protrudes outward from the peripheral edge of the disk 53 and can be brought close to the fixed blade. In the meantime, the organic matter is destroyed and broken into pieces by the hammer effect.
