Fractionation processes based on physical separation are a good strategy to produce enriched cereal flours. Therefore, the aim of this work is to evaluate the suitability of sieving of buckwheat flours to produce protein and phenolic (especially rutin) enriched fractions. Because of that, dehulled whole buckwheat flour (GSTQ) was sieved obtaining fractions with a particle size of 215 µm, 160 µm, 85 µm, and 45 µm (GS215, GS160, GS85, and GS45). For that purpose, the determination of protein, ash, and total starch content and free and bound phenolic compounds was carried out. The highest content of total phenolic compounds was obtained in GS215 (3118.84 mg kg−1 d.w.), followed by GS160 (2499.11 mg kg−1 d.w.), GS85 (989.46 mg kg−1 d.w.), GSTQ (983.15 mg kg−1 d.w.), and GS45 (481.31 mg kg−1 d.w.). Therefore, the phenolic content decreased with the particle size decrease from 215 µm to 45 µm. Besides, there were no significant differences between the total phenolic content in GS85 and GSTQ. The fraction with 215 µm reported the highest protein and mineral salt content and presented rutin amounts four times higher than GSTQ.

Classification Efficiency

Hydraulic classifier is widely used in the mill plant，But the design of traditional hydraulic classifier is simple，less controllable factors, cause the inaccuracy of Classifying product particle size，low classification efficiency. In order to solve these problems, the paper puts forward a new hydraulic classifier, we can improve the efficiency of classification by improving the appearance structure of hydraulic classifier and taking two pieces of top water. In the lab，the classification test was conducted with the coarse slime (0.9~0.3 mm, 0.3~0.074 mm) from Yanma coal preparation plant under the two phase of water supplying. The results of test show that by using two phase of water supplying, the new hydraulic classifier Can improve the classification effect of coarse coal slime.

Recently, a novel biomass pulverization technology was proposed by our group. In this paper, further detailed studies of this technology were carried out. The effects of feed moisture and crusher operational parameters (rotor speed and blades gap) on product particle size distribution and energy consumption were investigated. The results showed that higher rotor speed and smaller blades gap could improve the hit probability between blades and materials and enhance the impacting and grinding effects to generate finer products, however, resulting in the increase of energy consumption. Under dry conditions finer particles were much more easily achieved, and there was a tendency for the specific energy to increase with increasing feed moisture. Therefore, it is necessary for the raw biomass material to be dried before pulverization.
