In general, a one-stage roll mill is a type of mill in which a pair of rollers are arranged side by side, and solid foods to be crushed are supplied between the pair of rollers, and the two rollers are rotated at a ratio of 2: 1. Compressive stress, shear stress, etc. are applied to the solid foodstuff to grind the solid foodstuff.

The grain size of the solid edible crushed by the conventional single-stage roll mill does not become the desired particle size, until the solid edible milled by the conventional single-stage roll mill reaches the desired particle size. The solid mill is fed again to the roll mill several times. Thus, the conventional single-stage roll mill took considerable time for the solid food to be crushed to the desired size.

In addition, in order to solve the disadvantages of the conventional single-stage roll mill, by installing a plurality of the conventional single-stage roll mill continuously, the solid edible to continuously pass through the plurality of single-stage roll mill to reduce the grinding time will be. However, such an automation method requires a large installation space for several conventional single-stage roll mills.

Therefore, such an automated method has been difficult to introduce in small mills (eg mills).

Accordingly, the present invention provides a method and apparatus for reducing the required power while increasing the crushing efficiency to the extent that the solid foods can be supplied to the roll mill to obtain the desired particle size of the solid foods without increasing the installation space. The main purpose is to.

As shown in Fig. 1, the three rollers 9, 12, 14 have the same diameter, and the two rollers 9, 12 are arranged in parallel at regular intervals with respect to the horizontal plane. One first roller 9 rotates clockwise by a driving means such as a motor, and the other second roller 12 rotates counterclockwise by a transmission means. At this time, the rotation speed of the second roller 12 is smaller than the rotation speed of the first roller 9. The third roller 14 is positioned below the middle between the first and second rollers and is arranged in parallel with the first and second rollers at regular intervals. The third roller 14 is rotated clockwise by another transmission means, and has the same rotational speed as the rotational speed of the first roller 9.

In the state in which the rollers 9, 12 and 14 of the same diameter are arranged and rotated as described above, the solid food is first introduced between the first and second rollers. When the solid food is introduced between the first and second rollers 9 and 12, the solid food is first crushed and passed between the first and second rollers so that the first, second and third The rollers flow into the space A, which is defined.

The first crushed solid edible introduced into the space A passes through the second mill 12 and the third roller 14 while being crushed secondly and is discharged out. The first crushed solid food product introduced into the space A does not pass between the first roller 9 and the third roller 14, and the second roller 12 and the third roller 14 do not pass. The reasons for passing through are as follows.

The third roller 14 is rotated in the same speed and in the same direction as the first roller 9, and rotates in the opposite direction to the second roller 12 to a speed greater than the rotational speed of the second roller 12 Have. Therefore, the third roller 14 has a speed greater than the rotation speed of the second roller 12.

As described above, since the first roller 9 and the third roller 14 rotate in the same direction, the solid foodstuff introduced into the space A is formed between the first roller 9 and the third roller 14. I can't pass. Therefore, the solid foodstuff introduced into the space A passes between the second roller 12 and the third roller 14 which rotate in opposite directions.

As described above, the solid foods introduced into the space A are forcibly prevented from passing through the first roller 9 and the third roller 14 which are rotating in the same direction. The capacity is several times higher than the grinding capacity of the conventional two-stage roll mill.
