Description

Technical Field

[0001] The utility model relates to the technical field of dryers, in particular to a feed crushing device for dryers. Background Art

[0002] As we all know, a dryer is a mechanical device that uses heat energy to reduce the moisture content of materials and is used to dry objects. The dryer vaporizes the moisture in the material (generally refers to water or other volatile liquid components) by heating to obtain solid materials with a specified moisture content. The purpose of drying is to meet the needs of material use or further processing. According to the operating pressure, dryers are divided into two categories: atmospheric pressure dryers and vacuum dryers. According to the operating pressure, they can be divided into atmospheric pressure and reduced pressure (reduced pressure dryers are also called vacuum dryers);

[0003] In the production process of chicken essence, a drying device is often required. When the drying device is fed, if the material agglomerates and does not meet the drying standards, the material is prone to being dried thoroughly, resulting in poor overall material product quality. In addition, when the material is crushed and filtered, the filter device needs to be cleaned regularly. Traditional filter devices are mostly fixed on the inner wall of the discharge pipe, which is not convenient for disassembly and cleaning, and is inconvenient to use. Utility Model Content
