Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a crushing apparatus for crushing food plants such as tea leaves or medicinal plants such as medicinal plants into fine powder having a fine particle size.

[0002]

2. Description of the Related Art Conventionally, a crushing device using a stone mill or a sealed container has been known as a device for producing a fine powder having a particle size like matcha. Stone mortar has been used since ancient times and can produce the best quality powder (for example, matcha), but its production efficiency is poor, and it is not preferable for safety and hygiene because the powder comes out like spilling from the stone mortar. Especially in the case of tea leaves, Chinese herbs, etc., perform thorough management from the viewpoint of health and safety,
Its production requires a great deal of nerve, and there is also an environmental problem that the working environment is damaged by dust.

Further, a typical conventional crushing device is provided with a hermetically-sealed container rotatably supported and a driving means for rotating the hermetically-sealed container. In this crushing device, when crushing, a suitable ball-shaped member such as a ball-shaped mineral (alumina, steatite, zirconium, etc.) is put in the sealed container together with the object to be ground, and the sealed container is moved in a predetermined direction by the driving means. It is rotated. When such a crusher is used, sealing work is possible, so safety and health problems and dust problems are solved, but strong and long-term stirring is required to make fine powder. Therefore, the device generates heat, and the generated heat may change the quality of the material to be crushed. Also, the size of the powder is not uniform, and it is necessary to sort through a filter or the like. Therefore, it is not so problematic in the production of tea leaf powder used for confectionery and cooking, but it is difficult to apply it to the production of high-grade matcha used for tea ceremony known as "Ousu".

Under these circumstances, a crushing device using a special cooling device has also been proposed in order to prevent deterioration due to heat. However, even if a cooling device is used, its cooling effect is limited, and not only the quality but also the device itself becomes large, and the manufacturing cost thereof is high, and further the energy efficiency is poor.

In order to solve these problems mentioned above,
A crushing device has been proposed in which an object to be crushed and a ball-shaped member are put together in a hermetically sealed container, and the hermetically sealed container is revolved about a first axis and is rotated about a second axis (for example, See Patent Document 1). In this crushing device, due to the interaction between the ball-shaped member and the object to be crushed, a large shearing force acts on the object to be crushed. Can be shaped.

Then, the first rotation shaft 32 is rotationally driven in a predetermined direction by the electric motor 64. When the first rotary shaft 32 rotates in this manner, the pair of rotary plates 34 and 36 rotate integrally with the first rotary shaft 32, and the cylindrical sealed container 38 rotates (revolves) around the first rotary shaft 32 at the first angular velocity. It At this time, since the rotation of the main pulley 44 and the sub-pulleys 46a to 46d is restricted by the first and second belts 50 and 58, each cylindrical sealed container 38, as described above, corresponds to the corresponding second rotation. It is rotated (rotated) about the axis at a second angular velocity. When the above-described first and second angular velocities at the time of rotation are appropriate, the contents (the object to be crushed 84 and the ball-shaped member 86) in the cylindrical closed container 38 are rotated by the centrifugal force to revolve the cylindrical closed container 38. Is pressed against the inner peripheral surface (the surface defining the crushing space 80) of the outer cylinder member 74, and at the same time, the contents (the crushed object 84 and the ball-shaped member 86 are crushed by centrifugal force, Coriolis force, and gravity due to rotation. 2) rub against each other, drop while colliding with each other, and repeat mixing, and such a complicated circulating motion acts on the contents in the crushing space 80. Therefore, during this circulation movement, the crushed object 84 has a ball-shaped member 86 and a cylindrical closed container 3 between the ball-shaped members 86.
8 between the inner cylinder member 72 and the outer cylinder member 74 and between the pin-shaped member 82 and the inner cylinder member 72, a frictional action, a pressing action, a collision action, and the like are performed. The crushed object 86 is crushed into a fine powder.

The crushing by this crushing device is carried out by using tea leaves, herbs,
It can be used for processing dried products of various plants (dried stems, dried roots, dried fruits) and the like into powder, and can be conveniently applied particularly to the processing of high-grade green tea.

The above-mentioned crushing device has the following features. Conventionally, a crushing device called a ball mill has been known, but this ball mill merely rotates a closed container, and a crushing medium simply circulates so as to roll in the closed container. Although such a ball mill can be expected to have a certain degree of crushing effect, the time required for crushing is long, and the temperature of the object to be ground rises. On the other hand, in the above-described crushing device, a state of being sandwiched between the crushing media (ball-shaped members 86) or between the crushing medium and the inner cylinder member 72 and the outer cylinder member 74 of the cylindrical closed container 38. At this point, they are slightly rubbed with each other due to the pressure (a squeaky feeling), whereby the contents are efficiently mixed without the heavy grinding medium moving in the cylindrical closed container 38 unnecessarily. In addition, a large pressure can be applied between the grinding media. As a result, the temperature rise of the object to be crushed 84 is small, and it becomes possible to efficiently crush the object to be crushed 84 into a fine powder in a short time.
For this reason, as the ball-shaped member 86, one having a specific gravity as large as possible is used, and the cylindrical closed container 38 is not simply rotated, but is also centrifugally utilized between the grinding media and between the grinding media and the cylinder. It is desirable to rotate the airtight container 38 with a relatively large radius of gyration and angular velocity so that a pressure is generated between the inner cylinder member 72 and the outer cylinder member 74.

Further, in the above-mentioned crushing device, since the cylindrical hermetically sealed container 38 revolves around the first rotating shaft 32 and rotates about the second rotating shaft 32, the contents in the crushing space 80 ( Object to be crushed 84 and ball-shaped member 86)
Is less likely to cling to the inner peripheral surface of the outer cylindrical member 74 of the cylindrical hermetically sealed container 38, and is agitated by rolling in the crushing space 80. It is preferable that the crushing space 80 of the cylindrical closed container 38 is not so large. If the crushing space 80 is large,
As the cylindrical sealed container 38 rotates, the contents are crushed into a crushing space 80.
The rolling distance in the inside becomes long, frictional heat is generated by this rolling movement, and the problem of thermal deterioration occurs, and therefore it is desirable that the size thereof is not so large.

Further, in the above-mentioned crushing apparatus, the cylindrical sealed container 38 revolves around the first rotating shaft 32 and rotates about the second rotating shaft 32. Therefore, the outer peripheral surface of the cylindrical sealed container 38 ( The outer cylinder member 74) is effectively cooled by the ambient air, and its temperature rise is suppressed. In addition, as in the embodiment, the inner tubular member 72 is formed into a tubular shape,
A space is created inside the inner tubular member 72, and this space is communicated with the outside (although not shown, a plurality of spaces are provided in the end walls 76, 78 of the tubular sealed container 38 corresponding to the space of the inner tubular member 72. By providing a communication hole), the cylindrical sealed container 38
The inner peripheral surface (inner tubular member 72) of the above is also effectively cooled, and the temperature rise of the tubular sealed container 38 can be further suppressed.

In such a crushing device, the cylindrical closed container 3
The revolution speed and the revolution speed of No. 8 are appropriately set depending on the type of the crushed object 84 and the like.
Is determined to generate sufficient pressure by centrifugal force,
The rotation speed is determined so that the crushed object 84 and the ball-shaped member 86 are agitated and mixed as required. The revolution speed and the revolution speed depend on the ball-shaped member 86 to be used. However, if the revolution direction and the revolution direction are opposite to each other as described above, the absolute value of the revolution speed is different from the absolute value of the revolution speed. The speed can be set to a fraction of a fraction, and by setting in this way, it is possible to improve the crushing efficiency while maintaining the quality of the object 30 to be crushed.

In this crushing apparatus, it is desirable to use a ball-shaped member 86 having a surface which is not glossy and has an appropriately rough surface state. When the crushed object 84 such as tea leaves is crushed using a crushing medium having a smooth surface, when the particles of the crushed object 84 become fine to some extent, the powdery crushed object 84 causes the inner surface of the cylindrical hermetically sealed container 38 to fall. It sticks to cover, resulting in a decrease in grinding efficiency and uneven particle size during grinding. On the other hand, when the object 84 to be crushed is crushed by using a crushing medium having an appropriately rough surface state with no gloss, a pressing force with a shearing force generated when the surfaces of the ball-shaped member 86 collide with each other. And the collision force effectively act on the object to be crushed 84, so that the cylindrical sealed container 3 is not only efficiently crushed but also has a file-like effect.
The phenomenon of sticking to the inner surface of 8 is also reduced, and the crushed object 84 is efficiently crushed. In consideration of such a fact, the surface roughness of the grinding medium, that is, the ball-shaped member 86 is set. If the surface condition is too fine, the desired particle size cannot be obtained even if it takes a long time, and the gloss is The same phenomenon occurs as when the ball-shaped member 86 is used, and the grinding efficiency is reduced.

The diameter of the ball-shaped member 86 is preferably 2 to 10 mm. When the diameter is less than 2 mm, the energy per collision is small and the pulverization efficiency is low. On the other hand, if this diameter exceeds 10 mm, the number of points that come into contact with each other with collision or friction will decrease,
Therefore, even in this case, the grinding efficiency is reduced. It is desirable that the diameter of the ball-shaped member 86 be smaller than that of a grinding medium used in a ball mill or the like.

In the crushing apparatus described above, the crushing space 80 is defined between the inner cylinder member 72 and the outer cylinder member 74. By providing the inner cylinder member 72 in this way, the crushing efficiency can be further enhanced. When the object to be crushed 84 is put together with the ball-shaped member 86 in an ordinary cylindrical closed container (which does not have an inner cylindrical member) and the rotary motion is performed (revolution and rotation) as described above, With the progress, the powdery pulverized object 84 comes to float in the portion near the center of the cylindrical closed container, and it floats as if it floated on the ball-shaped member 86 forever despite stirring by rotation. Due to this, the crushing effect is reduced. On the other hand, when the inner cylinder member 72 is provided inside the outer cylinder member 74 in the radial direction like the above-described crushing device to make the crushing space 80 annular, there is almost no space in which the object to be crushed 84 floats and the object to be crushed The object 84 is positively involved in the movement of the ball-shaped member 86, and is pressed so as to be sandwiched between the inner cylindrical member 72 and the ball-shaped member 86, so that the object 84 to be crushed is effectively ball-shaped. As a result of being agitated and mixed with the member 86, the object 84 to be ground can be ground more efficiently and substantially uniformly into a fine powder.

In this crushing device, since a plurality of protrusions (pin-shaped members 82) are provided on the outer peripheral surface (the surface defining the crushing space 80) of the inner cylindrical member 72, the object to be crushed 84 is further crushed. It can be pulverized more efficiently. By providing the inner tubular member 72 with a plurality of protrusions, the tubular sealing member 3
When 8 rotates, these protrusions act on the contents (the object to be crushed 84 and the ball-shaped member 86) in the lower part of the crushing space 80 to stir and mix, and this stirring and mixing action is promoted to mix more efficiently. Thus, the crushing effect by friction, pressing, collision, etc. accompanied by shearing force acting between the ball-shaped members 86 and between the ball-shaped members 86 and the inner surface of the cylindrical hermetically sealed container 38 is further enhanced, and a shorter time is obtained. In time, high quality fine powders such as matcha powder can be made.

In the above-mentioned crushing device, since four cylindrical closed containers 38 can be used, the crushing device can be used once (with the device operating time of 20 minutes) for 2 times.
It is possible to obtain 0 kg of matcha powder. In addition, since the type of tea leaves to be charged can be changed for each hermetically sealed container 38, it is possible to obtain a large variety of tea leaf powders at one time, and the energy required for processing is small. Further, since the object to be crushed 84 is not exposed to the outside during crushing, there is no problem in hygiene and there is no problem of dust. Therefore, it is also environmentally friendly to the worker.
