Effect Of Steam Pressure And Conditioning Temperature During The Pelleting Process On Phytase Stability, C. N. Truelock, N. E. Ward, J. W. Wilson, C. R. Stark, C. B. Paulk
Kansas Agricultural Experiment Station Research Reports
This experiment was designed to evaluate the effects of steam pressure and conditioning temperature on the stability of microbial phytase. Treatments were arranged as a 2 × 3 factorial of steam pressure (24 and 44 psi) and conditioning temperature (170, 180, and 190°F). Phytase was added to a corn-soybean meal-based diet and mash samples were collected for phytase analysis. The diet was pelleted via steam conditioning (10 × 55 in Wenger twin staff pre-conditioner, Model 150) and using a pellet mill (CPM Model 1012-2) with a 3/16 × 1 1/4 in pellet die (L:D 6.7). Conditioner retention time was set …

Kansas Agricultural Experiment Station Research Reports
This experiment was designed to evaluate the effects of pellet mill die thickness and conditioning temperature on the stability of microbial phytase. Treatments were arranged as a 2 × 3 factorial of die thickness (L:D 5.6 and 8.0) and conditioning temperature (165, 175, and 185°F). Phytase was added to a corn-soybean meal-based diet and mash samples were collected for phytase analysis. The diet was pelleted via steam conditioning (10 × 55 in Wenger twin staff pre-conditioner, Model 150) and using a pellet mill (CPM Model 1012-2) with a 5/32 × 7/8 in (L:D 5.6) or 5/32 × 1 1/4 in …
