For example, in supermarkets and convenience stores, fresh foods and processed foods are placed on plastic trays and packaged in plastic wrap, and vegetables are sold in plastic bags or plastic wraps. Discarded. On the other hand, in restaurants and the like, most foods such as leftover food and unsold food are discarded in an unpackaged state.
[0007]
However, even if the food is unpackaged, for example, if vegetables and the like are put into the decomposition device as it is, it takes a long time to decompose the food because the area in contact with microorganisms (the area per volume) is small. . Conversely, in order to process the food in a short time, it is necessary to make the food as fine as possible and increase the area in contact with microorganisms (the area per volume). Since there is no means for crushing, the food must be finely crushed manually, which is inefficient.

[0038]
According to the food decomposition processing apparatus 1 of the present example having the above-described configuration, when the waste food is the food to be packaged, the waste food is put into the separation processing mechanism unit 40 and separated into the food as the content and the package. Then, the separated food is automatically fed into the decomposition processing mechanism unit 10. Further, in the case of food such as vegetables, which have a small area per volume in contact with microorganisms, the food is introduced into the crushing mechanism 60, finely crushed, and then automatically introduced into the decomposition mechanism 10. On the other hand, foods having a large area per volume, such as liquid foods (soups, uncles, etc.), rice, noodles, etc., are directly introduced into the decomposition treatment mechanism unit 10. Then, when the waste food is put into the decomposition treatment mechanism section 10, it is decomposed by microorganisms, and a liquid fertilizer is generated by this decomposition action. Hereinafter, a specific process in each mechanism unit will be described.
[0039]
<Separation processing mechanism>
In the separation processing mechanism 40, first, the lid 54 is opened to open the input port 43, and the food to be packaged is input from the input port 43. After the input, the input port 43 is closed by the lid 54. Then, the food to be packaged introduced from the introduction port 43 slides down the chute portion 42a, is introduced into the separation tank 12, and comes into contact with the second blade bodies 47, 49 which are driven to rotate in the direction of arrow B. As a result, the package is broken, and subsequently, the first blades 46 and 48 agitate the rotary shaft 44 around the axis. As a result, the package of the packaged food is unwrapped, and the package and the food as its contents are separated.
[0040]
Then, when the separated package and food are stirred by the first blades 46 and 48, they are pushed in the axial direction of the rotating shaft 44 by the stirring main surface (surface) and move in the coaxial direction. Then, during the movement process, the food is discharged from the food discharge port, and then is introduced into the decomposition processing mechanism unit 10 through the guide duct 58. On the other hand, the package is discharged out of the tank from a package discharge port 42c formed in the direction in which the axis of rotation of the rotating shaft 44 extends, and is collected in the collection box 57 through the discharge duct 56.
[0041]
In addition, when the lid 54 is opened to open the input port 43, the rotten odor (unusual odor) in the separation tank 42 may leak to the outside. In this example, when the lid 54 is opened, Since the water or the deodorant is configured to be automatically injected from the nozzle 55, the injection prevents the rotten odor from leaking to the outside.
[0042]
<Crushing process mechanism>
In the crushing processing mechanism section 60, first, the lid 87 is opened to open the upper opening of the crushing tank 63, and a food with a small area per volume such as vegetables is introduced from this opening. The opening is closed by 87. Then, the introduced food comes into contact with the baffle plate 84, and the baffle plate 84 rotates together with the support shaft 85, so that it falls downward and is placed on the holding plate 71.
[0043]
Next, the food placed on the holding plate 71 is pushed (punched) in the rotating direction of the movable blade 67 by the concave curved surface portion 68 of the movable blade 67 driven to rotate in the direction of arrow C by the drive motor 83, The movable blade 67 and the fixed blade 73 cooperate to cut and crush the thin pieces, and the crushed pieces fall down through the notches 72 of the holding plate 71.
[0044]
When the food on the holding plate 71 is hit by the moving blade 67, the food may jump upward due to the reaction. In this case, the bounce plate prevents the food from moving upward more than necessary by the jump. This prevents the food from jumping out of the upper opening of the crushing tank 63.
[0045]
The crushed pieces that have fallen downward from the notch 72 of the holding plate 71 are pushed below the holding plate 71 in the direction of rotation by a delivery body 75 that rotates in a state where the phase is inverted by 180 degrees with respect to the moving blade 67 ( It is moved in the same direction by being hit, and is discharged to the outside through the discharge port 80 by the centrifugal force generated at that time, and is introduced into the disassembling mechanism 10 through the guide duct 81.
[0046]
<Disassembly mechanism>
In the decomposition processing mechanism 10, the food separated by the separation processing mechanism 40 is put into the decomposition tank 12 from the first receiving port 27, and the food crushed by the crushing processing mechanism 60 is transferred to the second receiving port 28. From the decomposition tank 12. When the food is put into the decomposition tank 12, the main stirring blade 18 and the auxiliary stirring blade 20 which are driven to rotate in the direction of arrow A by the rotating shaft 14 are stirred together with the bacterial bed and air is supplied inside. . In addition, the temperature in the decomposition tank 12 is adjusted to an appropriate temperature by temperature adjusting means.
[0047]
In this way, air is supplied to the sediment composed of the waste food and the bacterial bed, and when the air is maintained at an appropriate temperature, the microorganisms carried on the bacterial bed are activated, and the waste microorganism is decomposed by the activated microorganism. As a result, a liquid fertilizer, that is, a liquid fertilizer is produced.
[0048]
At this time, the main stirring blades 18 and the auxiliary stirring blades 20 are provided so that the main stirring surfaces of the main stirring blades 18 and the auxiliary stirring blades 20 are inclined with respect to the axis of the rotating shaft 14, and the main stirring blade 18 and the auxiliary stirring blades adjacent to each other in the axial direction of the rotating shaft 14. Since the blades 20 are arranged such that the stirring action directions of the stirring main surfaces thereof are opposite to each other in the axial direction, the waste food and the bacterial bed to be stirred are in the axial direction of the rotating shaft 14. It moves so as to undulate in the axial direction by receiving the acting force in the direction along, and the movement makes it easier for air to enter the inside, thereby activating microorganisms and promoting the decomposition of food.
[0049]
In addition, liquid foods such as soups and uncles, foods having a large area per volume such as rice and noodles, are introduced into the decomposition processing mechanism 10 without passing through the separation processing mechanism 40 or the crushing processing mechanism 60. In this case, the lid 30 is opened to open the charging port 13, and the charging port 13 is directly charged into the decomposition tank 12.
[0050]
At that time, the putrefaction odor (offensive odor) in the decomposition tank 12 may leak to the outside from the opened inlet 13, but in this example, when the lid 30 is opened, water or water disappears from the nozzle 29. Since the odorant is configured to be automatically injected, the injection prevents the putrefaction odor from leaking to the outside.
[0051]
Then, the liquid fertilizer generated in the decomposition tank 12 is discharged from the discharge port to the drain pipe 22, and what overflows over the weir plate 23 is discharged from the pipe 24 to the outside of the system. Water is supplied from the water supply pipes 25 and 26 into the drain pipe 22, and the water is discharged from the outlet to the drain pipe 22 to dilute the concentration of the liquid fertilizer.
[0052]
As described above in detail, according to the food decomposition treatment apparatus 1, the food to be packaged can be automatically separated into the food and the package as contents without requiring any manpower. Since small-area food can be automatically and finely crushed, waste food can be efficiently decomposed as compared with the related art.
[0053]
As mentioned above, although one Embodiment of this invention was described, the specific aspect which this invention can take is not limited to this at all.
[0054]
For example, in the above example, the main stirring surfaces of the main stirring blades 18 and the auxiliary stirring blades 20 are flat, but may be curved surfaces like screws.
[0055]
A nozzle similar to the nozzles 29 and 55 is provided near the opening of the crushing tank 63, and when the lid 87 is opened, water or a deodorant is automatically injected from the nozzle into the crushing tank 63. May be configured to be performed.
