通过恒温干燥以及变温干燥两种不同的热风干燥方式,研究了苦瓜切片在不同热风温度、切片厚度以及风速等因素条件下的热风干燥特性,并绘制了含水率曲线及干燥速率曲线。结果表明:热风温度和风速对苦瓜干燥影响较大,厚度影响相对较小;变温干燥时,干品色泽比恒温干燥好。这些可为苦瓜切片热风干燥工艺的改进提供一定的理论依据。
通過恆溫榦燥以及變溫榦燥兩種不同的熱風榦燥方式,研究瞭苦瓜切片在不同熱風溫度、切片厚度以及風速等因素條件下的熱風榦燥特性,併繪製瞭含水率麯線及榦燥速率麯線。結果錶明:熱風溫度和風速對苦瓜榦燥影響較大,厚度影響相對較小;變溫榦燥時,榦品色澤比恆溫榦燥好。這些可為苦瓜切片熱風榦燥工藝的改進提供一定的理論依據。

Through constant temperature and variable temperature drying , the two different hot air drying methods , this paper has studied the hot air drying characteristics of bitter gourd slices in different air temperature , wind speed , the slice thickness and other factors , and drawn the water cut curves and drying rate curves .The results show that:the hot air temperature and wind velocity have a big effect on the drying process , thickness effect is relatively small .Variable tem-perature drying is better than the constant temperature drying from the dry goods color perspective .The research can pro-vide a certain theory basis for improvements of bitter gourd slices hot-air drying process .
