摘　　要：螺旋式速冻机是速冻食品厂家的主力冻结设备之一。国内螺旋吹风式速冻机与国外相比效率低下 ,其中料口严重跑冷是主要原因之一。对螺旋式速冻装置的异侧同高度料口的运行工况进行了实验研究 ,建立了包括料口在内的螺旋吹风式速冻装置三维数学模型 ,并进行了数值模拟 ,求解使用PHOENICS软件。进行了流场分析并给出此料口布置工况下的最佳改进方案。The spiral quick-freezer is one of the main freezing equipments used in the quick-freezing industry. Compared with foreign equipments, those of our domestic are more inefficient, the mess and heat transfer at the entrance and exit is one of the main causes of the energy loss. In this paper, aiming at the air flow organization at entrance and exit set at the same height, but the different sides, experimental investigation was carried out, and a 3-dimension mathematical model was set up, numerical simulation is given,solved with PHOENICS software. Finally, advanced plan was given according to the analysis on flow field.
