Abstract

The present invention has a basic structure of millstone, a traditional grain mill, and relates to a mill mill using electric power with greatly improved grinding performance.

The present invention is a basic structure of millstone, which is our own traditional grain grinder, and is transformed so that it can be conveniently mass-produced using electric power. 8,10), grains and water (not used for the production of dry flour) will be processed in the impact chamber → adjustment chamber → grinding chamber.

In the shock chamber, the fixed mill 14 and the rotating mill 16 are each vertically (perpendicular to the axis of rotation) and are recessed in a gear shape at regular intervals with an obliquely inclined groove {cross section: right triangle (Fig. 3)}. When the grain flows in between the grooves, it goes down and hits the edges of the protrusions of the opposite millstones 14 and 16, which are broken by impact. The process is repeated so that the grains are broken down to the same size as the gap between the two millstones. You lose. The broken grains are collected in the control chamber (ⓑ) and immediately transferred to the grinding chamber (ⓒ). In the grinding chamber ⓒ is pushed down, crushed, ground and crushed into smaller and smaller particles while being pushed down along the rotational direction between the gap between the fixed mill 14 and the rotating mill 16. At this time, the gap between the stationary mill 14 and the rotary mill 16 is in close contact with each other, and since the inclination (tilt angle) of the entire friction surface stays for a long time, the grains of the grain become very small.

Description

Electric millstone {ELECTRIC METDOL}

The present invention is a basic structure of millstone, our own grain grinder, which has been modified to add functionality and make use of mass production and electric power for convenient use.

Conventional millstones used by our ancestors have a concave circle with two millstones in the form of a fixed millstone, a rotating millstone on top of them, and an A-shaped wooden handle that can be turned by hand on the edge of the mill. Needed.

In addition, by using electric motors such as electric motors and V-belts and by giving a plane or arbitrary inclination angle to the machining surface, the machining performance was improved.

The purpose of the present invention is to modify the structure and function of the conventional millstone to significantly improve the grinding performance to enable the production of high quality powder (solution) in large quantities .

According to the present invention, the electric mill is composed of three parts according to the functional characteristics of each part, such as the impact chamber, the control chamber, and the grinding chamber.

First, the grain to be crushed (two or more kinds can be mixed) is put into the grain storage container (2) and the grain is supplied to the control valve (8). {The water reservoir (6) and the control valve (10) are not used in the production of dry flour) The impact chamber (ⓐ) is inclined at an angle to the stationary mill (14) and the rotating mill (16) vertically (perpendicular to the axis of rotation). The groove {section: right triangle (Fig. 3)} is dug into gears at regular intervals. Grain flows between the grooves, moves along an oblique side down by gravity, and is exposed out of the groove. Since (16) is turning, it encounters the edge of the protrusion of the opposing millstone (fixed and rotated). The impact breaks the grain, and the process is repeated over and over, eventually breaking into two millstones.

Grain collected in the adjusting chamber (ⓑ) by gravity moves to the grinding chamber (ⓒ). In the grinding chamber (ⓒ), the machining surface tilted obliquely between the fixed millstone 14 and the rotating millstone 16 along the direction of rotation is lowered. It is pushed into the mill, crushed and crushed by up and down millstones, and then grinds into smaller and smaller particles. At this time, the gap between the stationary mill and the rotating mill is in close contact with each other, and since the inclination (tilt angle) of the entire friction surface is gentle and stays for a certain time, the grains of the grain become very small.

As described above, according to the present invention, the fixed mill 14 and the rotating mill 16 of the impact chamber are each inclined at an angle to the vertical (right angle with the rotating shaft) {cross section: right triangle (Fig. 3)} at regular intervals. Since it is geared into a gear, the grain introduced between the grooves moves along an oblique plane downwards and then encounters and collides with the edge of the protrusion of the opposite millstone (fixed and rotated). The particles are crushed in successive collisions until they are in the form of grains. Thus, the grains are broken into small particles in the impact chamber before they even reach the grinding chamber, which greatly improves the grinding capacity in the grinding chamber. It will be possible to mass-produce using electric power such as shortening and processing of high quality grain.

Claims (1)

Electric mills for the purpose of crushing grains are divided into functions such as impact chamber (ⓐ), adjustment chamber (ⓑ) and grinding chamber (ⓒ).
