OPTIMIZATION OF PARAMETERS OF THE MIXER FOR PREPARATION OF FEED FROM BY-PRODUCTS OF STARCH PRODUCTION
The purpose of this study was the practical implementation of health pilot mixer for preparation of feed from by-products starch and syrup production and identify optimal design and operating parameters. The mixer consists of a housing with placed in it a screw-mixer, which has a hollow shaft with sequentially arranged on a screw-wound and hollow blades. On the body of the mixer is mounted a hopper for loading mixed materials. At the end of the mixer from the hopper there is a feeder of the extract. It contains the camera of the extract with a membrane and a support for holding the shaft of the screw mixer. The camera is mounted a spring, one end fixed to the unit casing and the other on the support. The article presents the results of the multivariate three-level three-factor experiment to find the optimal settings of the mixer. The results of the experimental data multi-factor experiment the constructed response surface and the lines of equal level, which characterizes the degree of homogeneity and specific energy consumption of the oscillation amplitude of the membrane and the hole diameter of the blades at frequency of rotation of the working body of 100 min-1. In the experiment established optimal design and operating parameters of the mixer for preparation of feed from by-products of starch production. The proposed design of the mixer is efficient and can cook a variety of mixtures with a high degree of uniformity.
