| 摘 要： | 通过搭建的果蔬差压预冷实验台分别研究了不同的送风速度、开孔大小、开孔形状及排列方式,对球形果蔬在差压预冷过程中所产生的影响,实验结果发现：风速越大球形果蔬降温速率越快,冷风送风速度1.5～2m/s为最经济送风风速;椭圆形的送风口球形果蔬降温速度最快;交叉排列摆放方式降温速度快,但降温的均匀性较差;

| Abstract: | Pressure pre-cooling experimental device is established and experimental the effects of spherical fruits and vegetables pre-cooling process have been conducted different airflow rates,vent hole form and vent hole size.Results showed that pre-cooling rates are quicker with the increase of airflow rates and the most economic choose is that the airflow rate between 1.5 and 2m/s.Pre-cooling rates with ellipse vent hole are the quickest and cooling uniformity with the lay-outs of cross arrangement is better but the cooling homogeneity is poor. |
