Study on the Spray Drying Technology of Protein Zymolite Solution
摘要
Abstract
[Objective] The purpose of the study was to explore the control condition of spray drying technology of protein zymolite solution. [Method] The protein zymolite solution was dried by centrifugal spray drying and the best technological parameters were obtained through analyzing inlet air temperature, rotation speed of atomizer, discharge air temperature and temperature in collector. [Result] The influence of inlet air temperature on the physical properties of wall-hanging matter showed that the better inlet air temperature was 150 - 170 ℃. The influence of inlet air temperature on the acceleration of material and liquid flow showed that the acceleration of material and liquid flow was enhanced by 1.5% -2.5% when the inlet air temperature was enhanced for 1 ℃ and the best inlet air temperature was 160 - 170 ℃. The influence of discharge air temperature on wall-sticking showed that the best discharge air temperature was 80-85 ℃. The influence of rotation speed of atomizer on production showed that the better rotation speed of atomizer was 15 000 -18 000 r/min. The better technological condition for drying protein zymolite solution was as follows: the inlet air temperature was 160 - 170 ℃ , the discharge air temperature was 80-85 ℃ , the temperature in collector was 50 ℃ and the rotation speed of atomizer was 15 000 r/min. [Conclusion] The study provided theoretical support for the application of spray drying technology in drying protein zymolite solution.关键词
