It is explanatory drawing which shows schematic structure of the waste-waste culture processing apparatus for obtaining a suitable waste-waste culture medium used as a raw material of livestock feed in this embodiment.

  Hereinafter, livestock feed according to the present invention will be described with reference to the drawings. FIG. 1 is an explanatory diagram showing a schematic configuration of a waste medium processing apparatus for obtaining a suitable waste medium used as a raw material for livestock feed in the present embodiment. The waste spent medium processing apparatus shown in FIG. 1 adjusts the particle size of the dried waste spent culture medium, and then circulates and uses a portion of the coarse particles as fuel and collects the fine particles as raw materials for livestock feed. Is. The feed for livestock according to the present embodiment is mainly composed of a waste culture medium mainly composed of corn cob produced after artificial cultivation of enoki mushrooms.

  The waste medium treatment apparatus 100 shown in FIG. 1 supplies combustion gas generated by burning heavy oil using the heavy oil burner 10 to the hot air generator 20 as hot air at the start of operation. The hot air supplied to the hot air generator 20 is supplied to the vertical dryer 30 via the hot air supply path 22. The hot air supply path 22 is connected to a hot air intake portion 32 disposed at the bottom of the vertical dryer 30. As shown in FIG. 1, the vertical dryer 30 is formed in a vertically long shape, and the hot air taken in from the hot air intake unit 32 rises in the internal space of the vertical dryer 30 and is located above the vertical dryer. The product is discharged from the provided discharge port 34 to the outside of the vertical dryer 30.

  In the vertical dryer 30, a rotary crusher 33 is disposed at a position below the hot air intake unit 32, and a drying processing object supply port is provided at a position above the hot air intake unit 32. A waste medium supply port 36 is provided. The drying medium supply port 42 is connected to the waste medium supply port 36. Here, a feed screw is used as the drying object supply path 42. A mixer 44 having a material inlet 40 for introducing the waste medium is disposed upstream of the drying object supply path 42. Here, a paddle mixer was adopted as a mixer.

  The waste medium supplied from the material input port 40 is supplied to the waste medium supply port 36 via the mixer 44 and the drying process target supply path 42 and is input to the internal space of the vertical dryer 30. . At start-up, the waste medium passing through the mixer 44 is simply transported.

  The waste medium introduced into the internal space of the vertical dryer 30 is pulverized by the rotary crusher 33 disposed at the bottom of the vertical dryer 30 and discharged to the hot air intake unit 32 side (scraping up). In other words, the hot air from the hot air intake unit 32 is subjected to a drying process. As described above, since an upward flow due to hot air is generated in the internal space of the vertical dryer 30, the waste waste medium (dried waste waste medium) dried by the hot air is combined with the hot air in the vertical dryer. The interior space 30 is raised to the upper position and discharged from the discharge port 34 to the outside of the vertical dryer 30.

A transport path 38 is connected to the discharge port 34 of the vertical dryer 30. The downstream end of the conveyance path 38 is connected to a cyclone furnace 50 for separating the mixture of hot air and dry waste waste medium, which is a dried body, into hot air and dry waste waste medium.
The hot air separated by the cyclone furnace 50 is exhausted by a bag filter 52 typified by a water scrubber and then discharged into the atmosphere.

  On the other hand, the dried waste waste medium separated from the hot air by the cyclone furnace 50 is divided into approximately two parts by passing through the dividing portion 60 formed in the inverted Y-shaped tube. One branching destination 62 in the dividing unit 60 opens toward the return conveyor 66, and about half of the dry waste waste medium is discharged to the return conveyor 66. At the end position of the return conveyor 66, a second input section 46 of a paddle mixer which is a mixer 44 is installed in a positioned state.

  Since the dry waste waste medium supplied from the return conveyor 66 to the mixer 44 has passed through the vertical dryer 30 at least once, the waste waste medium (as a dry processing object to be fed from the material inlet 40) ( The water content is significantly lower than the water content (50%) (water content 10 to 20%). In this way, the dry waste waste medium having a low water content is mixed with the waste waste medium introduced from the material input port 40 by the mixer 44, whereby the dry waste waste medium is supplied to the vertical dryer 30 from the drying object supply path 42. A so-called pre-drying treatment can be performed in which the moisture content of the waste medium is about 30%, which is about half of the initial moisture content. By using the waste medium that has been pre-dried in this way as an object to be dried, the processing time of the vertical dryer 30 can be shortened, and the temperature of hot air to be supplied into the vertical dryer 30 can be reduced. For example, the load on the vertical dryer 30 can be reduced.

In addition, a vibration sieve 70 that is a classification unit is disposed at the other branch destination 64 of the dividing unit 60. The vibrating sieve 70 is for separating the corn cob, which is the main component of the waste medium, into a coarse particle and a fine particle based on a predetermined particle size by a drying process using hot air (vertical dryer 30). is there.
The coarse grain in the waste medium contains almost no nutrients but is rich in caloric components. On the other hand, the fine-grained portion of the waste culture medium is not suitable as a combustion material because there are few components that become calorie and ash is defective, but it is rich in so-called nutrients. As described above, the waste medium can be divided into a coarse fraction for fuel (component having a particle size larger than 2 mm) and a fine granule for livestock feed (component having a particle size of 2 mm or less). .

  The fine granule fraction of the dried koji waste medium containing a high concentration of nutrients that has passed through the vibrating sieve 70 is recovered by the recovery unit 80 as a raw material for livestock feed. An appropriate amount of Animase Aiwa containing a plurality of types of natural plant digestive enzymes provided by Aiwa Co., Ltd. is mixed with the fine granule fraction of the dried koji waste medium collected in the collection unit 80. In this way, a livestock feed excellent in nutritional components can be obtained by mixing Animase Aiwa with the fine particles of the waste medium from which water has been sufficiently removed. In addition, although the moisture content of the dry waste liquid culture medium immediately after collect | recovering by the collection | recovery part 80 is about 10 to 20%, when mixing animase and Aiwa, the moisture content is about 5 to 15% by natural drying etc. It is preferable to use the dried waste waste medium.

  In this embodiment, an appropriate amount of rice bran and bran represented by rice bran and bran and so-called concentrated feed is mixed into the mixture of the fine granule of the dried koji waste medium and the animase and aiwa to make the feed for livestock with higher nutritional value. . The mixing ratio is not particularly limited, but the dry waste medium is 80 to 90%, the animase aiwa is 5%, and the mixture of bran and concentrated feed is 5 to 15% (both are mass ratios). It is preferable to do this.

  The livestock feed obtained as described above may be supplied to a pelletizer and processed into a pellet shape as necessary. The moisture content of the material to be pelletized is 5 to 15%, which is a favorable moisture content for the pelletizer. Livestock feed processed into pellets by a pelletizer is advantageous in that it is easier to transport and store compared to the state before pelletization.

  For the effective use of the fine particles as described above, the dry waste waste medium remaining on the vibrating sieve 70 is supplied to the circulation supply path 90. The downstream end of the circulation supply path 90 is connected to the hot air generator 20. The circulation supply path 90 is transported by the air supplied by the blower fan 92.

  In the present embodiment, as shown in FIG. 1, the circulation supply path 90 is connected to the fuel supply port 24 provided at the same height as the combustion gas supply port of the heavy oil burner 10 in the upper position of the hot air generator 20. It is connected. If dry waste waste medium as fuel is supplied from the fuel supply port 24, hot air can be generated only from the dry waste waste medium. As described above, once the dry waste waste medium as the fuel for continuous operation is supplied from the circulation supply path 90 to the hot air generator 20, the dry waste is discarded as long as the new waste waste medium is continuously supplied from the material input port 40. Only the culture medium can be burned in the hot air generator 20 to obtain hot air. As a result, the amount of heavy oil used can be greatly reduced as compared with the drying apparatus for waste waste medium according to the prior art.

  In addition, in the dried soot waste medium for coarse particles supplied to the circulation supply path 90 as a fuel for continuous operation, components that become solidified bodies after combustion are greatly reduced. By using the dry waste waste medium in which such components are reduced (removed) as a fuel for the hot air generator 20, adhesion of solidified components to the inner wall surface of the hot air generator 20 is greatly suppressed (prevented). This is advantageous in that the maintenance frequency of the hot air generator 20 can be reduced.

Although the animal feed using the waste medium according to the present invention has been described in detail above based on the embodiment, the present invention is not limited to the above embodiment.
For example, in the above embodiment, the heavy oil burner 10 is used as a heat source supply unit at the time of starting the waste waste medium processing apparatus 100. It is also possible to adopt a burner. Moreover, the pellets manufactured in advance can be supplied to the circulation supply path 90 or the hot air generator 20 as a fuel for continuous operation.

Moreover, the supply operation of the waste culture medium from the material input port 40 is controlled by an operation control unit (not shown) so that the supply amount per hour of the waste culture medium supplied to the material input port 40 is constant. A form may be adopted.
Furthermore, the moisture content measuring means for measuring the moisture content of the waste medium supplied from the material input port 40 is provided with one or more of the material input port 40, the drying object supply path 42, and the mixer 44. In addition, an operation control unit (not shown) that adjusts the amount of the waste culture medium input to the material input port 40 in accordance with the water content of the waste culture medium measured by the moisture content measuring means may be provided.

  Although not shown, a hot air temperature adjusting unit that adjusts the temperature of hot air supplied to the vertical dryer 30 may be disposed in the hot air supply path 22. As the hot air temperature adjusting unit, it is preferable to employ an outside air intake port or a heat exchanger that takes in outside air. The hot air temperature adjusting unit may be configured to control the operation by the second control unit based on the temperature measured by the thermometer disposed in the hot air supply path 22 or the vertical dryer 30. . In particular, when a heat exchanger is employed in the hot air temperature adjustment unit, if a power generation device (not shown) using thermal energy obtained by the heat exchanger is further added, the waste medium treatment apparatus 100 can be operated independently. It is possible and preferable.

  Moreover, in this embodiment, although the reuse method of the waste culture medium including the manufacturing method of the livestock feed using the waste culture medium processing apparatus 100 shown in FIG. 1 is illustrated, it is limited to this manufacturing method. Is not to be done. As a waste culture medium mainly composed of corn cob which is a main constituent of livestock feed according to the present invention, it is also possible to use one obtained by purchase or the like.

  Furthermore, in this embodiment, the roughage in the livestock feed is composed of a waste waste medium, but is not limited thereto. In the livestock feed according to the present invention, in addition to the waste medium and the mixture of straw, the rough feed is mixed with the waste medium and the mixture of green grass or silage, and further, the waste medium and the mixture of straw and green grass or silage. It can also be configured.
