The flow state of fried capsicum sauce, as solid-liquid two-phase flow, inside of stirred tank was studied by numerical simulation analysis. Helical ribbon paddles was selected to analyze the fluid velocity field, density field and the distribution of volume fraction of each phase in stirred tank under the condition of different band width. The simulation results showed that: helical ribbon bandwidth had a great impact on fluid flow distribution in stirred tank. It was known by comparing different bandwidths that the agitation axial velocity on solid-liquid mixture could be increased by adding the bandwidth properly; and the turbulent area was increased, the solid-liquid mixture was mixed evenly with better effection. The results provided theoretical basis for design of horizontal stirred tank of fried capsicum sauce, which had a certain practical significance.
