Abstract
With the transformation of China’s agricultural development direction and the vigorous promotion of healthy green condiments, the demand for drying materials such as pepper powder, grain and fruit is increasing, while the traditional drying method is low in efficiency, long drying time, and materials are easy to be contaminated by sediment and various microorganisms. So this article use numerical method to simulate the heat pump drying room air distribution, by changing the internal disturbance conditions, different drying stage and the different initial conditions, characteristics of flow field inside the drying room changes, buoyant jet is analyzed in different initial velocity, initial temperature and the effect of flow field characteristics of Chinese prickly ash drying room; The purpose is to provide theoretical support and design guidance for the design of the hot pump-type pepper drying room.
