| Abstract: |
| In order to provide reference for the development and application of extruded soybean powder products, the processing technology of extruded soybean powder in non-resistant environment, key equipments and key control indicators were summarized according to the practical experience of production.In addition, the applications of extruded soybean powder in piglets, dairy cows, poultry and aquatic feed were overviewed. Extruded soybean powder was produced by the process of impurity removal, crushing, grinding, conditioning, extruding, cooling, drying and crushing. The key equipments of the extruded soybean powder production included raw material crusher, hammer mill, conditioner, extruder, flip plate cooler, finished product crusher and other equipment. The key indicators of extruded soybean powder were mainly anti-nutritional factors (urease activity 0.01-0.03 U/g), KOH nitrogen solubility index(75%-80%), fat (17%-20%), crude protein (35%-39%), moisture (≤12%), and particle size (0.85 mm screen passing rate ≥90%), which could be controlled by adjusting production process and process parameters. Extruded soybean powder could be used in the feed of piglets, dairy cows, aquatic products and poultry, which had the advantages of promoting digestion and absorption, improving production performance. In summary, the production process of extruded soybean powder is simple, and it has a very important significance for improving the economic benefits of breeding. |
