益生菌固体饮料混合工艺的优化

Optimization of Mixing Technology of Probiotic Solid Beverage

为提高益生菌固体饮料混合工艺的混合均匀度,采用响应面试验设计优化混合操作条件。以混合时间、混料量和混合转数频率为3个主要因素,以混合均匀度为响应值,采用响应面法设计优化混合工艺参数。结果表明,益生菌固体饮料混合工艺最佳参数为混合时间11 min、混料量400 kg、混合转数频率40 Hz。在此条件下,混合均匀度为91.62%,与模型预测的理论值91.01%比较接近,说明响应面分析优化所得混合工艺参数准确可靠,可用于实际生产操作。

In order to improve the mixing uniformity of the probiotic solid beverage mixing process,response surface test design was used to optimize the mixing operation conditions.Taking mixing time,mixing amount and mixing rotation frequency as the three main factors,with mixing uniformity as the response value,the response surface method was used to design and optimize the mixing process parameters.The results showed that the best parameters of the probiotic solid beverage mixing process were mixing time 11 min,mixing amount 400 kg and mixing rotation frequency 40 Hz.Under this condition,the mixing uniformity was 91.62%,which was close to the theoretical value of 91.01%predicted by the model,indicating that the mixed process parameters optimized by response surface analysis were accurate and reliable and could be used in actual production operations.
