Determination on mixing homogeneity of wheat flour;

A V-mixer is most used in a premix mill and a pharmaceutical factory,in order to study the effects of different load factors and mixing times on the mixing homogeneity of premixes,to find out the rational load factor and the optimum mixing time of a V-mixer in production of additive premixes.

The quadratic regression orthogonal rotary method was adopted to study the offect of three different mixing homogeneity: mixing time, block coefficient and rotary speed of the paddle shaft, also study the dominant effect, the single effect and interactive effect.

The concept on the accuracy of measuring the mixing uniformity of feeds is stated.

In the experiments, iron powder was used as the tracer to evaluate the mixing uniformity.

Taking mixing uniformity as assessment index,the mixing performance and mechanism of adjustable head fall mixer with grids were studied in a plant scale experiment.

Study on mixed degree of uniformity of enzymes in bread additive;

This study focused on some key techniques in the industrialized manufacturing of edible fungus culture medium,including automatic weighing,uniform mixture of raw materials and rapid water infiltration.

The uniform mixing action and hooked fiber hook problem of a carding machine are discussed.
