The preparation of bone meal is an effective method for the resource utilization of bone, which is made of bone through cleaning, degreasing, enzymolysising, drying, ultra-fine pulverizing, etc. Drying is a key step in the preparation of bone meal. In this paper, the moisture content and drying rate are designated as the indexes, and the effects of temperature,weight and enzymolysis on moisture content and drying rate are studied. Based on the experimental results, the dynamic model of bone drying is obtained by using mathematical analysis and comparing three experience and semi-experience mathematical model, which provides technical parameter forprocessing technology and production equipment design. The experimental results show that the dynamic model of bone-meal is consistent with Page model.
