Phytase is a phosphohydrolytic enzyme that releases phosphorus from phytate in animal feed. However, pelleting is a thermal process that can denature phytase. It is hypothesized that there are many factors that can account for phytase denaturing during the pelleting process, such as pellet mill model, die length to diameter ratio (L:D), steam quality, and residence time in conditioner and die. Therefore, the objective of this experiment was to determine the effect of pellet mill model, die thickness, and die retention time on pellet quality and phytase stability. Treatments were arranged as a completely randomized design to determine the effect …


The Effects Of Filter Type And Warm-Up Time On Pellet Durability Index Using The Holmen Nhp100 Portable Pellet Tester, C. E. Evans, R. N. Kort, M. Saensukjaroenphon, H. K. Wecker, C. B. Paulk, C. R. Stark Jan 2019

The Effects Of Filter Type And Warm-Up Time On Pellet Durability Index Using The Holmen Nhp100 Portable Pellet Tester, C. E. Evans, R. N. Kort, M. Saensukjaroenphon, H. K. Wecker, C. B. Paulk, C. R. Stark

Kansas Agricultural Experiment Station Research Reports

The Holmen NHP100 (TekPro Ltd, Norfolk, UK) is a portable forced air pellet tester commonly used by the feed industry to determine the pellet durability index (PDI). The objective of this study was to determine the effect of filter type and machine warm-up time on PDI. A corn-soybean meal-based grower diet was conditioned at 185°F for 30 sec and subsequently pelleted using a laboratory pellet mill (Model CL5 California Pellet Mill Co., Crawfordsville, IN) equipped with a 0.16- × 0.5-in die. Production rate was 120 lb/h. Once cool, pellets were analyzed for PDI using the NHP100 with a 60-sec run …


Effect Of Pellet Die Thickness 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 Jan 2019

Effect Of Pellet Die Thickness 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 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 …


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 Jan 2019

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 …


Pelleting And Starch Characteristics Of Diets Containing High Amylase Corn, C. N. Truelock, M. D. Tokach, C. R. Stark, C. R. Paulk Jan 2019

Pelleting And Starch Characteristics Of Diets Containing High Amylase Corn, C. N. Truelock, M. D. Tokach, C. R. Stark, C. R. Paulk

Kansas Agricultural Experiment Station Research Reports

This experiment was designed to evaluate the effects of die thickness and conditioning temperature on pelleting and starch characteristics in diets containing either conventional yellow dent or high amylase corn (Enogen®, Syngenta Seeds, LLC). Treatments were arranged as a 2 × 2 × 3 factorial of corn type (conventional and high amylase), die thickness (L:D 5.6 and 8.0), and conditioning temperature (165, 175, and 185°F). For the high amylase corn treatments, ground high amylase corn replaced conventional ground corn on a lb:lb basis. Diets were pelleted via steam conditioning (10 in × 55 in Wenger twin staff pre-conditioner, …
