| 摘 要： | 预冷是保证贮藏果蔬品质的一个重要措施。通过建立果蔬预冷时温度降速率、压力降速率及温度变化率的相关偶合式,分析了在一定摆放方式条件下的最好预冷风速,并通过预冷实验进行了验证。结果表明,偶合式能与实验结果相符合,并且在实验条件下,预冷风速在0.9～1.5m/s时,预冷方式能取得最好的效果。

| Abstract: | Precooling is one of the important methods to protect the quality of the stored products. The optimum precoolingair velocity on a certain stacked type was analyzed based on the couple formula of the falling rate of the temperature drop, thefalling rate of the pressure drop and the change rate of the temperature of the stored products. The results were tested by theexperiments. It showed that the couple formula could meet with the experiment result, and under the experimental conditions,when the precooling velocity was about 0.9m/s to 1.5m/s, there was an optimam economical result in the pre-cooling. |
