摘　　要：为研究龙眼变风速压差预冷耗能耗时效果,研制龙眼压差预冷试验装置。在相同风、温条件下,比较恒速送风和变速送风预冷效果,结果表明:根据龙眼预冷过程温变规律,采用变风速预冷龙眼,可以有效节省电能,减少预冷时间。龙眼压差预冷在1 m/s左右变风速预冷较为适宜。In order to research on energy and time consumption of longan- forced-air pre-eooling in different air flow rate, a forced-air pre-eooling experimental unit was established. Comparing the time and energy consumption of pre-eooling in identical air flow rate, the result showed that precooling longan in different air flow rate according to the Longan temperature characteristic of forced-air pre-cooling may save electrical energy, reduce time consumption. Pre-eooling longan was excellent in different air flow rate about 1 m/s.
