Abstract

Maltcrusher is an equipment for crushing ingredients in manufacture of beer, having a direct impact on the quality of beer. With the growth of beer consumption in China, demand for malt crushing in beer manufacturing is getting higher and higher. By analyzing the pros and cons of the existing grinding technology, I proposed the program of wet malt crushing. 

What I have completed in my papers including: 1) setting an overall program design and some major issues that need to address, including crushing rates problems, filtering problems and excessive maceration issues;2)going to design for feed rollers, crushing roller, and some mechanical parts of transmission and regulation mechanism, doing a finite element analysis of shafts and housings ; 3)for a motion simulation of machine ; 4)      optimizing further through failure analysis. 

The malt mill designed in this article is full of advanced technology , which have strong production capacity, convenient operation and high degree of automation. There are manual and automatic regulation modes, which is easy maintenance, having broad application prospects.
