摘要
螺旋式速冻机由于结构紧凑 ,冻品范围广等优点而广泛应用于速冻行业。但国内速冻机与国外相比效率低下 ,其中料口跑冷是造成螺旋吹风式速冻机效率低的主要原因之一。分析了螺旋吹风式速冻机料口跑冷的原因和机理 ,对跑冷量的计算进行了探索 ,并进行了实验研究和分析。
The spiral quick-freezing installation is widely used in the quick-freezing industry because of its compactness and broad applicability.The mess and heat transfer at the entrance and exit is one of the main causes of the energy loss of the spiral quick-freezing installation.With theoretical and experimental research,a technological analysis is presented and a calculation of the energy loss is given.
