板栗真空爆壳工艺及热力学过程分析

板栗的脱壳去衣是板栗进行深加工的首道程序,在现有爆壳技术中选择了真空爆壳技术进行研究,首先对影响板栗真空爆壳工艺的重要因素进行实验,并利用SPSS软件建立了爆壳率和失水率的回归方程,考察其对板栗爆壳规律的影响;然后根据真空干燥理论,建立了一系列板栗干燥爆壳过程的理论数学模型,并再次进行实验对所建立的爆壳模型进行验证,探索出能够适用于板栗干燥、爆壳过程中的失水模型,从而发现爆壳过程影响失水率、爆壳率的规律,为今后爆壳工艺的进一步优化和加工生产提供理论依据和参考。

The vacuum shelling process of Chinese chestnut

Shelling of Chinese chestnut is the first deep-processing procedures,this paper focus on vacuum shelling technology.Regression equations about the shelling rate and dehydrating rate was established with SPSS by taking a single factor experiment to analyze relationships between major factors influencing the chestnut vacuum shelling performance.Based on the theory of vacuum drying,a series of the mathematic models of drying and shelling process were found.Comparison between experimental findings and numerical results shows a good coherence,which offer a dehydrating model used for Chinese chestnut so that effects on the shelling rate and dehydrating rate during shelling process can be concluded,and provide the theoretical basis and guidance towards technique optimization of this process.
