Embodiments of the present invention will be described with reference to the drawings.

Reference numeral 1 denotes a main body containing a motor (not shown).
The rotating shaft of the electric motor protrudes from the upper surface of the main body 1, and a joint member 2 is attached to the rotating shaft.

Reference numeral 3 denotes a container table which is removably mounted on the main body 1. A shaft 11 of a cutter 10 to be described later is fixedly inserted through an insertion hole 4 formed in the center of the container table 3. I have.

Reference numeral 5 denotes an annular groove formed on the upper surface of the container base 3, and a packing 6 is disposed in the annular groove 5,
A glass container 7 which is detachably attached to the container is hermetically held. Numeral 8 is a rib formed in the annular groove 5 so as to protrude in the radial direction. The rib 6 locks the packing 6 and drops the packing 6 when the container 3 is turned upside down, for example, when the container 3 is mounted on the container 7. Has been prevented. Numeral 9 is a concave portion formed on the inner peripheral side of the annular groove 5 so that when packing the container base 3 and the packing 6, etc., the packing 6 can be removed by inserting a toothpick or the like.

In general, the tip of the cutter has the highest peripheral speed and good cutting workability. Therefore, it is better to be long in the radial direction as much as possible. Material is not cut,
The recess 9 must be reduced. For this reason, by forming the rib 8 in the vicinity of the concave portion 9 as described above, even if the concave portion 9 is small, a hole for inserting a toothpick or the like can be sufficiently provided, and the packing 6 can be easily removed. In addition, the cutting efficiency is not reduced.

A cutter 10 is attached to the container base 3. A shaft 11 of the cutter 10 is inserted into the insertion hole 4 of the container base 3, and a joint member 12 attached to the lower end of the shaft 11 rotates the electric motor. The cutter 10 is driven by engaging with a joint member 2 attached to a shaft (neither is shown).

The cutter 10 has a pair of first blades 13 and 14.
And a second blade formed in a direction orthogonal to the first blades 13 and 14
One of the first blades 13 and 14
Is a horizontal portion 17 connected to the shaft 11 mounting base 16 of the cutter 10.
The other of the first blades 13 and 14 has a low step portion 18 which is bent downward from the mounting base 16 and is located parallel to the upper surface of the container base 3 and below the horizontal portion 17. ing.

The second blades 15, 15 are bent upward to promote convection in the container 7 when the cutter 10 rotates, thereby improving the efficiency of material pulverization.

In general, in order to grind a material with a cutter, the cutting edge is made flat, and the greater the area of contact with the material, the greater the crushing force. After pulverization, it is difficult to pulverize and the grains become coarse. Therefore, the first blades 13, 14
As shown in FIG. 7, a flat portion 21 is provided at the cutting edge of the second blades 15, 15 so that the area of contact with the material is increased to shorten the pulverization time. By setting C to an acute angle of 45 degrees or less, after the material is crushed to a size about the blade thickness of the cutter, the cutting edge is cut into crushed grains and further crushed. In addition, by setting the cutting angle C of the cutter 10 to 45 degrees or less, the material is guided to the lower surface of the cutter 10, the material is sent to the outer peripheral side by centrifugal force due to the rotation of the cutter 10, and the tip of the bent portion 19 is Part and container stand 3
It is further crushed between the upper surface.

Next, based on the data summarized in the table of FIG.
The distance A between the horizontal portion 17 of the first blade 13 of the cutter 10 and the upper surface of the container base 3 will be described. This data was obtained by crushing 50 g of soybeans, passing them through JIS sieve # 32, and measuring the amount remaining in the sieve.

When the gap A between the first blade 13 having the horizontal portion 17 and the upper surface of the container base 3 is set to 5.5 to 8.5 mm, the remaining amount is 3.0 to 2.2% and the crushing efficiency is increased. Is good and the gap A is 6.
When set from 5 to 8.5 mm, the remaining amount is 2.2 to 2.3%
In addition, the crushing efficiency is better. Further, when the gap A is set to 7.5 mm, the remaining power is 2.2% and the power consumption is 250 W, so that the pulverization efficiency is the highest.

The gap A is less than 6.5 mm or 8.
If it is larger than 5 mm, the remaining amount of soybean increases, and the input (power consumption) to the electric motor increases, so that the crushing efficiency deteriorates. This is because if the gap A is set to be larger than 8.5 mm, the soybeans fall under the blade 13 and cannot be crushed, and if the gap A is set to less than 6.5 mm, the blade 13 hits near the lower end of the soybean. This is because it is difficult to grind.

Then, the material pulverized in the horizontal portion 17 and the low step portion 18 is blown outward by centrifugal force, and further guided downward along the bent portion 19 at the tip. In the following, based on the data shown in FIG. 9, the distance between the tip of the bent portion 19 bent downward from the horizontal portion 17 and the upper surface of the container base 3 will be described. B
Will be described. This data is, as described above,
The measurement was performed with the gap A between the horizontal portion 17 and the upper surface of the container base 3 set to 7.5 mm.

When the gap B between the bent portion 19 and the upper surface of the container base 3 is set to 2.0 to 1.0 mm, the remaining amount becomes 2.0% or less, and the powder is efficiently crushed. Also, the gap B is set to 1.5
When set to mm to 1.0 mm, the remaining amount is 1.6% to 1.4%
And the crushing efficiency is good. If the gap B is less than 1.0 mm, the powder is further finely crushed. However, if the dimensions at the time of assembling vary, it hits the container base 3 and the upper surface of the container base 3 is cut off.

With the above structure, the material can be efficiently pulverized, and the low step portion 18 is formed on one of the pair of blades. The raw material is crushed in the gap between the low step portion 18 and the upper surface of the container base 3 to provide a smooth mouthfeel.

[0024]

According to the first aspect of the present invention, a material such as soybean is crushed at the horizontal portion of one blade, and finely crushed at a low step portion formed on the other blade. The material pulverized in the low step portion and blown off by centrifugal force can be further finely pulverized between the bent blade formed downward from the horizontal portion and the container base, and the pulverization efficiency can be improved. Further, the bent blade formed upward from the low step portion maintains the balance with respect to the rotation axis of the cutter, thereby preventing noise and vibration during rotation of the cutter.

According to the second aspect of the present invention, the material such as soybeans is pulverized in the horizontal portion of one blade, and finely pulverized in the low step portion formed in the other blade. The material crushed by the centrifugal force by the centrifugal force can be further finely crushed between the bent blade formed downward from the horizontal portion and the container base, and the crushing efficiency can be improved. Also,
By the bent blade formed upward from the low step portion, the balance with respect to the rotation axis of the cutter is maintained, and noise and vibration during rotation of the cutter can be prevented. Further, by forming the second bent blade bent upward at a position substantially orthogonal to the pair of blades, convection of the material in the container can be promoted during rotation of the cutter, and the pulverization efficiency can be further improved.
