Description

Technical Field

[0001] The utility model relates to the technical field of pulverizer equipment, in particular to a device for automatically detecting and adjusting the spacing between pulverizer rollers of a full-automatic pulverizer. Background Art

[0002] In the beer production process, first of all, select rice and malt of qualified quality for crushing, and the crushing degree should be moderate to facilitate the leaching and dissolution of the materials, which is conducive to the freeing of enzymes and improving the saccharification effect. Before crushing, it is necessary to add an appropriate amount of water to wet the surface of the barley malt 5-10 minutes in advance to form a good filter layer for subsequent wort filtration. The quality of wort has a vital impact on the quality of the final product. As a part of malt, the degree of damage of the bran does need to be controlled to ensure the quality of the wort. When carrying out the crushing process, it is necessary to ensure the integrity of the bran and avoid excessive damage. The reason is that the bran not only contains the main insoluble component-cellulose, but also contains a series of other soluble substances that may penetrate into the wort. These include malt polyphenols, bitter substances, silicates, and proteins. Once these substances are eluted into the wort in large quantities, they may have an adverse effect on the color and taste of the beer. Since cellulose itself is insoluble in water and is not easily decomposed by enzymes during the brewing process, its impact on the wort is relatively small. In order to ensure the quality of beer, we should minimize the damage of the bran to control these potential adverse factors.

[0003] In the beer production process, the grinding accuracy is usually controlled by controlling the spacing of the grinding rollers. The existing grinders usually adjust the spacing of the grinding rollers through manual debugging, which has a long debugging cycle, difficult operation, and reduces production efficiency.
