  The present invention relates to a crushing treatment apparatus and system for crushing raw materials into granular products of a predetermined size.

  Currently, when producing granular products such as so-called instant coffee, the powder is granulated, the granules are formed into plate-shaped raw materials, and the raw materials are granulated to a predetermined size by a crushing treatment device. Crushing into products.

As such a crushing processing apparatus, for example, there is an apparatus that strikes and crushes a raw material with a plurality of hammers rotatably supported (see, for example, Patent Document 1).
JP 2005-334866 A

  However, in a conventional crushing treatment apparatus that crushes raw materials by hitting them, many powders are generated from the product due to the impact. Such a powder cannot be used as a product of the desired size. For this reason, conventionally, it was necessary to exclude the generated powder from the product, which hindered the productivity of the product.

  The present invention has been made in view of the above-described problems, and provides a pulverization processing apparatus and system having a structure capable of maximally producing a product of a desired size while minimizing the generation of wasteful powder and the like. It is to provide.

  The pulverization processing apparatus of the present invention is a pulverization processing apparatus for pulverizing a raw material into a granular product of a predetermined size, which is relatively small in diameter with respect to a plurality of pulverization disk parts having irregularities formed on the outer peripheral surface. A plurality of spacer disc portions alternately arranged in a substantially horizontal axial direction, a plurality of crushing disc portions having irregularities formed on the outer peripheral surface, and a plurality of relatively small diameters The second crushed body, in which the spacer disk portions are alternately positioned in the substantially horizontal axial direction, the first crushed body and the second crushed body, and the outer peripheral surface of one crushed disk portion is the other. A crushing shaft support mechanism that is opposed to the outer peripheral surface of the spacer disk part and is supported in parallel substantially horizontally at a position where the outer peripheral parts of both crushing disk parts overlap in the axial direction, and Rotate the first crushed body and the second crushed body in the direction of moving downward at the position where the outer peripheral parts overlap each other. A crushing drive mechanism for driving and a number of through-holes through which a product of a predetermined size passes are formed, and the outer peripheral surface of the crushing disc portion of the first crushed body and the second crushed body is spaced at a predetermined interval from below. A predetermined distance on the outer peripheral surface of the crushing disc portion and the spacer disc portion from one end of the product separating member to the upper side of the first crushing body on the side opposite to the product crushing member facing the second crushing body On the outer surface of the crushing disc portion and the spacer disc portion from the one end of the product separating member to the upper side of the second crushing body on the side opposite to the first crushing body And a second return member facing each other at a predetermined interval.

  Therefore, in the crushing processing apparatus of the present invention, the first crushing body and the second crushing body are rotationally driven in a direction in which the outer peripheral portions of the crushing disc portions move downward at a position where they overlap each other. Therefore, the raw material thrown into the overlapping position from above is crushed into particles by being caught in the gap between one crushing disk part and the other spacer disk part. Since the crushed product moves on the surface of the product separating member by the rotation of the first crushed body and the second crushed body, the product crushed to a predetermined size falls downward from the through hole. On the other hand, the product that has not yet been crushed to a predetermined size moves from the surface of the product separating member to the surface of the first return member and the second return member by the rotation of the first crushed body and the second crushed body. . The first return member and the second return member face not only the crushing disc portion but also the outer peripheral surface of the spacer disc portion at a predetermined interval. For this reason, the product which has not yet been crushed to a predetermined size is guided by the first return member and the second return member to above the rotating first crushed body and second crushed body. And the product induced | guided | derived to the upper direction in this way is moved again to the position where the 1st crushing body and 2nd crushing body which rotate are overlapped. For this reason, a product that has not been crushed to a predetermined size is repeatedly crushed until it reaches a predetermined size.

  The pulverization processing system of the present invention is a pulverization processing system for pulverizing a raw material into a granular product of a predetermined size, and includes the pulverization processing apparatus of the present invention. There are a plurality of types of discs having different disc thicknesses as a crushing disc portion and a spacer disc portion with the crushing body. Therefore, in the crushing processing system of this invention, the disc thickness of the crushing disc part of a 1st crushing body and a 2nd crushing body, and a spacer disc part can be changed in several steps.

  In the crushing processing apparatus of the present invention, the raw material is introduced from above into a position where the first and second crushing bodies that are rotationally driven overlap with each other, so that The raw material can be crushed in the form of a gap with the spacer disk portion. For this reason, it can be crushed into granular form without hitting the raw material. For this reason, it is possible to produce products of a desired size to the maximum while minimizing the generation of wasteful powders. In addition, only products that have been crushed to a predetermined size fall downward from the through holes of the product separation member, and products that have not been crushed to a predetermined size are separated by the product separation member, the first return member, and the second return member. It moves again to the position where the 1st crushing object and the 2nd crushing object overlap. For this reason, a raw material can be reliably crushed to a desired size.

  In the crushing processing system of the present invention, the disc thickness of the crushing disc portion and the spacer disc portion of the first crushing body and the second crushing body can be changed in a plurality of stages. For this reason, the particle size of the product to be crushed can be adjusted in a plurality of stages.

For this reason, the 1st crushed object 110 and the 2nd crushed object 120 can be formed by mass production of the same components, and the productivity of the whole system can be improved.

  The inventor actually made a prototype of the crushing treatment apparatus 100 as described above, and performed a comparative experiment with a conventional hammer type apparatus (not shown) as shown below. In this experiment, the prototype device (not shown) was not equipped with a product separation member. On the other hand, the crushing treatment apparatus of the conventional apparatus is a product having a product separation member having a pore size.

  As is clear from the above experimental results, it was confirmed that the prototype device can disintegrate the raw material to the target particle size than the conventional device. In the prototype device, +4.75 mm over is 8.2%. This seems to be because most of the products are crushed depending on the disc thickness of the crushed disc part.

  Further, in the prototype device, the products are crushed by concentrating on a small diameter slightly smaller than the disc thickness of the crushing disc portion. This means that the desired particle size can be easily set and that most products are crushed to the set particle size.

  Furthermore, the present inventor also performed an experiment to change the disc thickness of the crushing disc portion with a prototype device as follows. In this case, a product separation member having a predetermined hole diameter was attached. Furthermore, the presence or absence of a return member was also compared.

  As is clear from the above experimental results, it was confirmed that the crushing particle size can be controlled by changing the disc thickness of the crushing disc portion. Furthermore, it was confirmed that the yield of a product of a desired size is improved by attaching a return member. This seems to be because the product is repeatedly crushed until it reaches the desired size.

  The present invention is not limited to the present embodiment, and various modifications are allowed without departing from the scope of the present invention. For example, in the said form, it illustrated that the unevenness | corrugation was formed in the outer peripheral surface only in the crushing disc part 210. FIG.

  However, as shown in FIG. 3, irregularities may also be formed on the outer peripheral surface of the spacer disk portion 220. In this case, since the raw material can be better bitten into the gap between the crushing disc portion 210 and the spacer disc portion 220, the crushing efficiency can be improved.

  Moreover, the said form illustrated that the crushing disc part 210 and the spacer disc part 220 of the 1st crushing body 110 and the 2nd crushing body 120 were separate bodies. However, the first crushing body 110 has a plurality of crushing units (not shown) including one crushing disk part 210 and one spacer disk part 220, and the plurality of crushing units are separated from each other. The second crushing body 120 has a plurality of crushing units (not shown) including one crushing disk part 210 and one spacer disk part 220, and the plurality of crushing units are provided.
