    摘要:

    以蘋(píng)果、黃瓜為實(shí)驗(yàn)對(duì)象,，通過(guò)對(duì)采后果實(shí)熱空氣處理中表面對(duì)流換熱系數(shù)的實(shí)驗(yàn)測(cè)定,，得到換熱實(shí)驗(yàn)關(guān)聯(lián)式。結(jié)果表明：在相同的熱空氣溫度下,，果實(shí)表面對(duì)流換熱系數(shù)隨空氣流速的增大而增大,；隨果實(shí)徑向尺寸的增大而減小,；采后果實(shí)作為生物體,，由于自身的蒸騰作用，傳熱過(guò)程中出現(xiàn)了流體的相變,，進(jìn)而導(dǎo)致?lián)Q熱效果顯著增強(qiáng),。

    Abstract:

    A test was applied to determine the heat transfer coefficients of apple and cucumber to obtain the experimental correlation of heat transfer. The results showed that the heat transfer coefficients of fruit increased with the increasing of air velocity, decreased with the increasing of radial dimension of fruit under the same condition of the hot air temperature. The heat exchange efficiency between fruits and hot air was enhanced significantly for the biological transpiration. Phase transition occurred in the process of heat transfer.
