Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to an electric food grinding device for grinding foodstuffs such as coffee beans, pepper beans, etc. or seasonings into particles of a required size.

[Prior art] Conventionally, in the electric food grinding device described above, a cutter is connected to the rotating shaft of an electric motor built into the main body case, and the cutter rotates in a desired direction as the electric motor is driven, thereby causing the inside of the main body case to be crushed. Food products or seasonings put into the machine are ground into particles of the required size.

[Problems to be solved by the invention] However, the above-mentioned conventional electric food grinding device
Since the food to be crushed is crushed into the required grain size by rotation of the cutter, the grain size of the food to be crushed was determined according to the rotation time of the cutter and the like.
For this reason, even if the rotation time of the cutter is constant, if there is a large amount of food to be crushed, it is difficult to crush the food to the desired grain size, and it is difficult to ensure that the grains are crushed to the same size. It was difficult. For this reason, the food to be crushed must be crushed while checking the particle size each time, resulting in poor workability.

[Purpose of the invention] The purpose of the invention is to
To provide an electric food pulverizer capable of pulverizing input food to be pulverized into a desired grain size and having excellent operability.

[Means for Solving the Problems] For this reason, the present invention provides a rotary bowl fixed to the upper part of a rotary shaft rotatably supported by the main body case, and a rotary bowl fixed to the rotary shaft located above the rotary bowl. A cutter blade, an electric motor that rotationally drives the rotating shaft, a fixed plate that is supported movably in the axial direction and circumferential direction of the rotating shaft in opposition to the rotating plate, and a fixed plate are attached to the main body case. a space adjustment screw that is fixed to the fixing plate by passing through a long hole formed in the circumferential surface of the main body case in an inclined state from below to upward; It is characterized by being equipped with a hopper case.

[Operation of the device] Since the present device is constructed as described above, the cutter blade rotated by the drive of an electric motor crushes the food to be crushed that has been input first into a certain size, and then cuts it into a fixed bowl. It is possible to grind the particles to a uniform size using a rotating mill. In addition, the distance between the stationary bowl and the rotary bowl can be adjusted by the spacing setting means according to the size of the grains of the pulverized food, allowing the food to be pulverized into different grain sizes.

[Example] An example of the present invention will be described below with reference to the drawings.

9 and 21.

The rotation shaft 1 is located at the center of the upper part of the main body case 3.
A boss 23 supporting 5 is integrally molded. A recess 27 surrounded by an upright wall 25 is formed in the upper part of the main body case 3 corresponding to the circumference of the boss 23. Engagement protrusions 25a are integrally formed on the outer peripheral surface of this standing wall 25 at required intervals. Further, a recess 29 is formed on the outer circumferential surface of the main body case 3, and a storage case 31 for storing crushed powder is removably inserted into the recess 29. An opening 33 is provided at the bottom of the recess 27.
is formed to communicate with the housing case 31, and the pulverized powder is introduced into the housing case 31 through the opening 33.

At the upper part of the main body case 3, there is a support case 7 that supports a fixing plate 35 that constitutes a part of the crushing section 9.
is removably attached. A hanging wall 7a is integrally formed in the support case 7 in accordance with the upright wall 25, and an engagement hole 7b is formed in the hanging wall 7a in accordance with the engagement protrusion 25a. The support case 7 is attached to the main body case 3 by engaging the engagement protrusion 25a with the engagement hole 7b. A long hole 7d is formed in the upright wall 7c of the support case 7 along its circumferential surface and inclined in the vertical direction. Inside the support case 7 is the fixing plate 3.
5 is supported so as to be slidable in the vertical direction. This fixed foot 35 is composed of a fixed holder 35a and female teeth 35b fixed to the fixed holder 35a. A nut portion 3 is attached to the fixed holder 35a.
5c is formed integrally with the nut portion 35c, and a fixing screw 37 as a spacing setting means that enters from the outside of the support case 7 through the elongated hole 7d is screwed to the nut portion 35c. The fixing plate 35 is attached to the support case 7 so that its attachment position can be adjusted in the vertical direction by a fixing screw 37.

A pair of upper and lower cutter blades 41 are attached to the upper part of the rotating shaft 15 at a required angle.
Further, a truncated conical rotary head 43 is fixed to the lower part of the rotary shaft 15 so as to face the fixed foot 35 . This rotary head 43 is composed of a rotary holder 43a and a toothed tooth 43b fixed to the rotary holder 43a.

A hopper case 1 is mounted on the upper part of the support case 7.
1 is removably attached to the hopper case 1.
A food to be crushed (not shown) such as foodstuffs or seasonings to be crushed is input into the container 1. In addition, 47 in the figure is a lid that closes the upper end opening of the hopper case 11;
9 is a power switch, 51 is a battery housed in the battery housing section 53, and 55 is a battery housing lid detachably attached to the lower end of the main body case 3.

Next, the operation of the electric food grinding device constructed as described above will be explained with reference to FIGS. 2 and 4.

First, to explain how to set the distance between the stationary foot 35 and the rotary foot 43, in FIG. 2 and FIG. 3
After loosening the screws 7, the fixing screws 37 are moved in the circumferential direction of the support case 7 along the elongated holes 7d depending on the size of the required particles to be crushed. As a result, the fixed foot 35 to which the fixed screw 37 is screwed moves upward while rotating along the inner peripheral surface of the support case 7, and the distance between the fixed foot 35 and the rotating foot 43 is widened. When the distance between the fixed foot 35 and the rotating foot 43 reaches the required distance, the nut portion 35c
Fixing screw 37 is screwed to support case 7.
The attached state of the fixing plate 35 to the fixed plate 35 is maintained.
In addition, FIG. 2 shows a state where the fixed foot 35 and the rotating foot 43 are maximally close together, and FIG. 4 shows a state where the stationary foot 35 and the rotating foot 43 are maximally separated. The distance between the fixed foot 35 and the rotating foot 43 is set within the range of the conditions shown in the figures and FIG.

When the power switch 9 is turned on after putting the food to be crushed into the hopper case 11 in the above state, the put-in food to be crushed is first crushed into a certain size by the rotating cutter blade 41. Then, the crushed food to be crushed to a certain size passes between the stationary bowl 35 and the rotating bowl 43, and is crushed into a particle size corresponding to the distance between the stationary bowl 35 and the rotating bowl 43. The crushed food ground to a required size is once stored in the recess 27 and then stored in the storage case 31 through the opening 33 as the rotary bowl 43 rotates.

In this way, in this embodiment, the food to be crushed put into the hopper case 11 is first crushed into a certain size by the cutter blade 41, and then the food is crushed into a fixed thin plate 3.
5 and the rotary mill 43, it is possible to grind the grains to a uniform size. The distance between the stationary bowl 35 and the rotary bowl 43 can be adjusted by moving the fixed bowl 35 up and down with respect to the support case 7, and it is possible to grind grains of different sizes depending on the food to be crushed. I can do it.

[Effects of the invention] As described above, the present invention can provide an electric food grinding device that is capable of grinding input food to be ground to the required particle size and has excellent operability. It is possible.
