BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a food crusher,
For example, soft ones such as walnuts and eggshells
It is possible to finely crush even a hard material such as

[0002]

2. Description of the Related Art In the processed food industry, social needs of health-oriented foods are increasing. Among them, as a material for health-oriented foods, an egg shell containing a large amount of calcium, which is said to be more likely to satisfy the required intake amount, has been attracting attention at present. Then, in order to make the calcium contained in the egg shell absorbable in the body, it was necessary to grind the egg shell into fine powder.

[0003] Among other health foods, walnuts are attracting attention as high energy foods. This walnut contains vegetable protein, and linoleic acid , a vegetable fat, normalizes energy metabolism and helps to prevent obesity. In addition, walnut fat contains a lot of unsaturated fatty acids, so it removes waste products in the blood,
It has the effect of strengthening blood vessels, preventing arteriosclerosis and lowering cholesterol. In addition, it is said to be effective for tonicity, stamina enhancement, cough, constipation, nervous breakdown, insomnia, beauty, and beautiful skin.

[0004] Processed foods have been developed in which this walnut is crushed and processed into a paste so that it can be easily mixed with other foods and eaten easily. Conventionally, as a food crushing device for health food materials as described above, at least one end has a blade, a rotary crushing unit that crushes the crushing object by rotating this blade, a rotational force to the rotary crushing unit There has been known a rotary drive source to be provided, and a storage container that covers the rotary crushing unit and hermetically seals water and a crushing target.

[0005] The rotary crushing section uses a rotary blade made of a thick rigid body. For example, when using an egg shell, which is attracting attention in health food materials, as the object to be crushed by this rotating blade made of a rigid body, it is crushed to a particle size of about 0.05 to 0.06 mm in about 5 minutes of crushing time. I was

[0006]

However, eggshells having the above-mentioned particle size are so large that it is difficult to ingest calcium in the body, and the particle size is at least about 0.03 mm or less. Unless crushed, the effect as a health food could not be expected. And even if the rotating speed of the rotary blade is increased to increase the grinding efficiency, the conventional food crushing device rotates the same position in a table shape at the same position because the rotary blade is formed from a thick rigid body. However, there is a problem in that it does not contribute to the refinement of the object to be crushed.

In view of the above, the invention according to claim 1 has been made in view of the above-mentioned problems of the prior art, and an object of the invention is to make it possible to vibrate the cutting edge in a vertical direction. An object of the present invention is to provide a food pulverizing device capable of fine pulverization.

As shown in FIG. 4, the container main body 43 has a substantially bottomed cylindrical bottom 47 having a thread groove formed on the outer peripheral surface of the upper end and having a lower portion whose diameter is larger than that of the upper portion, The cylindrical part 44 is screwed into the upper end of the bottom part 47 and formed vertically in a hollow cylindrical shape, and has a bottomed cylindrical lid 45 fitted into the upper end of the cylindrical part 44.

As shown in FIG. 1, the container body 43 has a lid 47 with a bottom 47 facing upward when crushing an object to be crushed.
The cover 45 is set on the rotary drive source 30 so that the cover 45 can be used with the cover 45 facing downward. As shown in FIG. 4, the cylindrical portion 44 opens upward, and has an outlet 46 into which the inner peripheral surface of the lid 45 can be fitted into the outer peripheral surface thereof.

As shown in FIG. 4, the annular partition wall 41 is
A conical partition 412 extending from the inner peripheral surface of the upper end of the bottom 47 toward the bottom wall 471 and gradually decreasing in diameter toward the bottom wall 471, and formed in a substantially conical shape, is connected to the conical partition 412. And a cylindrical partition 411 formed in a cylindrical shape vertically downward from the lower end of the conical partition 412.

As shown in FIG. 4, the cylindrical partition 411 has its lower end opened at a position upwardly away from the bottom wall 471 of the bottom 47. In addition, FIG.
As shown in FIG. 4, the cross-sectional shape is semicircular, and a total of four vent holes 42 for venting air are formed at 90 ° intervals in the circumferential direction.

As shown in FIG. 4, the bottom portion 47 has a storage portion 472 formed of a space sandwiched between the outer peripheral surface of the annular partition wall 41 and the inner peripheral surface of the bottom portion 47. Next, a procedure for using the food crushing apparatus 10 configured as described above and using an egg shell, which is one of health foods, as a crushing target will be described. First, from the state where the storage container 40 is mounted on the rotary drive source 30 and the rotary crushing unit 20 as shown in FIG. 1, the bottom 47 at the top of the storage container 40 is removed, and the top of the storage container 40 is opened. Assemble the object to be pulverized from above.

Next, from the upper part of the storage container 40, a predetermined amount of the egg shell and water to be crushed ,
Put white together. Next, as shown in FIG. 1, the dial 32 disposed at the lower front is rotated to a predetermined scale position. Thereby, the motor 31 rotates the drive shaft 33 of the motor 31 at a predetermined rotation speed in accordance with the numerical value of the scale,
The drive joint 222 of the coupling device 22 fixed to the upper end of the drive shaft 33 is rotated.

Then, in the coupling device 22,
The rotational force is transmitted to the driven joint 221 that meshes with the driving joint 222, and the rotating shaft 24 fixed to the upper end of the driven joint 221 also rotates, and the rotating shaft 24 is fixed at the upper end of the rotating shaft 24 by the nut 23 or the like. The blade 21 rotates. Accordingly, the rotary blade 21 rotates below the storage container 40 into which the egg shell and the water are charged, and the egg shell is crushed while being stirred inside the storage container 40.

At this time, as shown in FIG. 2, the rotary blade 21 is formed so that the cutting edge 213 of the rotary blade 21 can easily swing up and down by elastic deformation. When a force is applied from above or below the rotary blade 21, the cutting edge 213 of the rotary blade 21 is easily elastically deformed upward or downward. For this reason, the rotary blade 21
Does not rotate at the same position in the form of a table even when rotating at high speed, but rotates up and down. Thereby, the rotation range of the rotary blade 21 is widened, and the eggshell, which is the object to be crushed, is stirred, so that the eggshell can be finely crushed. For example, in 5 minutes of grinding time, the egg shell is 0.03 m
m, so that the calcium in the egg shell can be easily absorbed in the body.

Next, after the eggshell is crushed at a predetermined rotation speed for a predetermined time, the lid 45 of the storage container 40 is supported by the rotation driving source 30 in order to remove the storage container 40 from the rotation drive source 30. Department
Pull up from 34 and remove. At this time, the coupling device 22 can easily remove the driven coupling 221 from the driving coupling 222 simply by pulling up and down since the driven coupling 221 and the driving coupling 222 simply mesh with the irregularities.

Next, as shown in FIG. 4, the storage container 40 is repeatedly turned upside down, and the lid 45 of the storage container 40 is moved upward and downward.
When 47 is turned downward, the water containing the crushed egg shell is filled up to the inside water surface B of the lower part of the storage container 40. Then, if the egg shell is placed as it is for a predetermined period of time, the egg shell
Since the specific gravity of water is generally higher than the specific gravity of water, the bottom of the bottom 47 of the container body 43
Settles on wall 471. At this time, finely crushed egg shell
Does not sediment in the state of being suspended in water. to this
On the other hand, unmilled large egg shells
Settles in between. In addition, egg shell and egg yolk and egg white
Even when they are put together, the finely ground egg shell
It does not settle in the stirred egg yolk or egg white and is finely ground.
Only the large egg shells that did not settle out.

Thereafter, as shown in FIG. 4, the lid 45 is removed from the container body 43, and the container body 43 is gradually tilted.
Finely pulverized in the upper layer inside the container body 43 from the discharge port 46
Egg shells are mixed and white turbid water is gradually discharged. At that time, the large egg shell that was not pulverized
This large egg shell settles on the bottom wall 471 of the bottom 47 and is finely ground
Because the egg shells mixed are separated into white and cloudy water in two layers, the finely ground egg in the upper layer of the container body 43
Only water that is white and turbid due to the mixing of the shells is discharged from the discharge port 46 to the outside.

Further, the container body 43 is gradually inclined,
The crushed egg shell is mixed from the discharge port 46 to discharge the cloudy white water, and when the water surface descends, at the upper end of the bottom 47, the outer peripheral surface of the annular partition wall 41 and the inside of the bottom 47 A gap having a pressure lower than the atmospheric pressure is generated in a portion surrounded between the peripheral surface and the water surface. When external air enters the low-pressure gap, a ventilation hole 42 is formed in the middle of the cylindrical partition wall of the annular partition wall 41 so as to penetrate the front and back surfaces thereof.
The outside air gently enters the low-pressure gap formed between the annular partition wall 41 and the bottom portion 47 with “Sue”. For this reason,
Outside air enters from the lower end of the cylindrical partition part 411 as a large lump with the sound of “gob-go-bob”, and large particles settled between the lower end of the annular partition wall 41 and the bottom part 47.
Stir the egg shell and pulverize the large egg shell into finely ground egg shell
To prevent water from being mixed into white turbid water.
Can be.

This resulted in a large egg shell and finely ground
Egg shells are mixed and white turbid water can be kept in two layers, so that finely ground egg shells are mixed.
When the white turbid water is discharged from the discharge port 46,
With finely crushed egg shell mixed with white turbid water
Can prevent large egg shells from being discharged
You. Thereafter, as shown in FIG. 4, the storage container 40 is tilted in the horizontal direction, and the finely crushed egg shell is mixed through the outlet 46.
Even if the white turbid water continues to be drained and the horizon is further lowered at the time of discharge, the crushed large egg shell will be a circular partition wall
Enters between the outer peripheral surface of 41 and the inner peripheral surface of bottom 47, and finely pulverizes
Outlet 46 with white muddy water mixed with the egg shells
Will not be discharged outside.

Then, from the bottom portion 47 to the cylindrical portion 44 and the annular partition wall
41 and remove the large egg attached to the inner peripheral surface of the bottom 47 .
Only the shell can be removed. Also, in this embodiment,
A hard egg shell was used as the target, but the fibrous
Ri or tangerines may be put in with the skin.

In this embodiment, the ventilation holes 42 are formed on the outer periphery of the cylindrical partition 411 of the annular partition 41 at intervals of 90 degrees.
When the position for discharging water is fixed to a specific position of the discharge port 46, only one vent hole 42 corresponding to the discharge port 46 is required.
