optimation of double-drum drying technology in production and prelimilary feed formulatioan shrimp flake technology

The experiment was conducted to optimize shrimp flake processing technology and flake feed formulation by double-drum drying technology for the fist time. Orthogonal experiment was carried out to investigate the effect of steam pressure, drum rotate speed and slurry concentration on the flaking percent and floating performance of shrimp flake. In addition, the flaking performance of four flaking material, including 901, wheat flour, albumen and algin, were comparatively studied to chosen and quantify the optimum addition quantity of the suitable flaking material. Result clearly showe that the optimum technology are steam pressure0.4MPa, drum rotate speed 1000n／min and slurry concentration30%, and 901 is the suitable flaking material and the optimum addition quantity is 7%.
