Response Surface Optimization of Production of Instant Walnut Diaphragm Powder by Spray Drying and Analysis of Its Reconstitution Properties
摘要
Abstract
The aim of this study was to develop instant walnut diaphragm powder by spray drying. The operating parameters of spray drying were optimized. First of all, the one-factor-at-a-time method was used to investigate the effects of air inlet temperature, feed flow rate and hot air flow rate on the wettability, dispersibility, moisture content and particle size of walnut diaphragm powder. Then, we selected air inlet temperature, feed flow rate and hot air flow rate for the optimization experiments carried out by using response surface methodology. The responses were wettability and dispersibility. The results showed that the spray drying process was optimized as follows: air inlet temperature, 170℃; feed flow rate, 1.8 L/h; and hot air flow rate, 35 m3/h. The measured wetting time for the product under the optimized conditions was 13.2 s and the experimental dispersion time 5.8 s, which were in good agreement with the model predicted values.关键词
