Description

  The present invention relates to an apparatus for crushing or crushing an object into powder.

  There are several methods for pulverizing an object. Especially in the case of food, among objects, a ball mill pulverizer (for example, Patent Document 1), a pulverizer using two upper and lower mortars (for example, Patent Documents 2 and 3), There were an airflow type pulverizer, a roll crusher, and a pulverizer that combined an airflow type and a die (for example, Patent Document 4).

  The present invention relates to a pulverizer using the above-mentioned mortar. The pulverizer using a mortar includes an old-fashioned stone mortar and a recent metal mortar. Many old-fashioned millstones are pulverized by manually or automatically rotating the upper millstone at a low speed, and recent metal mills are often pulverized by automatically rotating the lower millstone.

  Recent pulverizers rotate faster to increase the efficiency of pulverization. However, if the rotation is faster, the temperature of the mortar and the object to be pulverized increases, and the possibility of degeneration increases. Therefore, many have a mortar cooling mechanism.

  The present applicant has also filed patent documents 5, 6 and the like.

  The introduction part of the metal mortar has a flat surface and is smooth. When the object to be crushed was thrown there, the object to be crushed was pressed between the introduction part of the flat upper mortar and the introduction part of the lower mortar, stuck and solidified. Once solidified, the lump became an obstacle, and the material to be continuously fed was clogged, and the material to be ground overflowed in the charging part. In this case, the crushing could not be resumed unless the space between the upper die and the lower die was opened and the operator removed the lump of the object to be crushed. Further, depending on the pulverized material, static electricity or surface tension was generated, and the material to be crushed stuck even in the charging portion, and the material to be pulverized did not enter the introduction portion and overflowed. Again, pulverization could not be resumed unless the object to be crushed was removed from the charging section. Furthermore, in both cases, even when the object to be crushed was removed and pulverization was resumed, the object to be crushed was immediately clogged again, and the pulverization could not be continued.

  An object of the present invention is to provide a pulverizer that can continue to operate smoothly without being clogged with continuously pulverized materials.
