[0034] The working principle of this utility model is as follows: In use, beer malt is first added to the feed inlet of the feeding box 13. The drive motor 21 rotates the actuating rod 22, guiding and dispersing the malt. Water is added inside the water pipe 23 to moisten the malt. After a brief soaking, the drive end control sealing switch 24 opens, allowing the soaked malt to drain into the wet pulverizer box 1. Two feeding boxes 13 are located at the top of the wet pulverizer box 1 for storage, enabling continuous malt pulverization. The drive motor 3 rotates the main stirring frame 4. Through the linkage of the main gear 14 and the driven gear 15, the main stirring frame 4 rotates in the opposite direction, causing the driven stirring frame 5 to rotate in the opposite direction. The spiral cutter bar guides the malt upwards during crushing, utilizing the staggered cutting blades 18 for crushing. The impact cutting and crushing of malt enhances the uniform crushing effect. At the same time, the operation of the drive motor 29 drives the rotating disk 10 to rotate, which in turn drives the swing rod 11 to swing. The swing rod 11 can lift and move the settled malt up and down, preventing the malt at the bottom from not being crushed. To ensure that the malt is not completely crushed in a single crushing process, the crushed malt can be taken out and placed inside the water filter frame 25 for water filtration. The crushed malt is then screened. After water filtration, the malt can be poured into the secondary grinding box 8 for grinding. After being crushed by the crushing wheel rod 16, the malt can be put back into the wet crusher box 1 for secondary crushing. Based on the previous data on the dryness and wetness of the crushed malt, the water supply tank 6 can be operated to periodically spray water downwards into the spray head rod 7 to humidify the malt during the crushing process, achieving a moisture-controlled, multi-crushing and screening effect for malt.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
