摘　　要：随着速冻食品行业的迅速发展,高效节能的速冻设备成为研究热点。对撞式速冻机具有冻结速度快,自动化程度高等优势。为了使对撞式速冻机内部气流组织更加合理,达到降低能耗的目的,需要对速冻机进行结构优化。本文通过归纳影响对撞式速冻机内部流场的因素,总结出喷嘴形状及尺寸、喷嘴距离网带的距离、静压腔尺寸和导流设备等因素对速冻机流场的影响。提出了进一步优化速冻机内部流场的设想,为后续对撞式速冻机的优化设计提供了理论基础。With the rapid development of the frozen food industry,efficient and energy-saving frozen equipment has become a research hotspot.The collision type quick freezer has the advantages of fast freezing speed and high degree of automation.In order to make the internal airflow organization of the collision type freezer more reasonable and achieve the goal of reducing energy consumption,it is necessary to optimize the structure of the freezer.This article summarizes the factors that affect the internal airflow organization of a collision type quick freezer,including the shape and size of the nozzle,the distance between the nozzle and the mesh belt,the size of the static pressure chamber,and the flow guiding equipment,which affect the flow field of the quick freezer.The idea of further optimizing the internal airflow organization of the quick freezer has been proposed,providing a theoretical basis for the optimization design of subsequent collision type quick freezers.
