Abstract: Malt quality is one of the main factors influencing wort filtration performance. This research adopted the small simulation filtering equipment to conduct wort filtration of malt samples. Meanwhile,a series of wort filtration performance parameters including 200 m L filtration time,total filtration weight and filter cake weight,20 s filtration performance,total filtration performance,and main impact indicators including the solubility and viscosity of malt,had been evaluated in filtering test. Laser diffraction particle size analyzer( Beckman Coulter LS 13 320) and coulter counting and particle analyzer( Beckman Multisizer 3) had been used in granularity analysis of wort before and after filtering. The particle size distribution of wort before and after filtering had been determined.,The relation of particle size distribution and the performance of wort filtration was evaluated.
