Millet bran, rice bran, wheat bran, brown rice,
sticky rice were wet pulverized by the high-pressure microchannel fludizer.The
effects of raw material, pressure and cycle times on particle sizes of the
samples were investigated.Effects of the high-pressure microchannel fludizer on
the microbial reduction were also studied. The experimental results showed that
the particle sizes of millet bran, rice bran, wheat bran, brown rice and sticky
rice were reduced significantly after the high-pressure microchannel fludizer
treatments.Especially, the particle size was remarkably reducedafter the first
cycle. The average particle diameter D50of brown rice and sticky
rice was reduced to less than 10 μm after the high-pressure microchannel fludizer
treatments. The results showed that the total number of microbialdecreased by
20 times, and the high-pressure microchannel fludizer played a role in
bacteria-reducing. Therefore, the shelf-life of liquid products can be extended.
