Optimization of air supply parameters in drying room of pig transport trucks

 Presents the structural characteristics and drying principle of type Ⅰ and type Ⅱ drying rooms. According to the actual air supply parameters of type Ⅰ drying room, optimizes the air supply process parameters of type Ⅱ drying room by theoretical analysis and CFD numerical simulation calculation. The results show that when the air supply temperature of type Ⅱ drying room is 80 ℃ and the air supply velocity on the side room is 2.0 m/s, the temperature and velocity of drying area can meet the requirements of drying, the uniformity of flow field is good, and the cost of energy consumption is 71.41 yuan in the time of temperature rise. Compared with the worst air supply scheme in the research range, the cost of energy consumption is reduced by 8.3%.
