Abstract
To realize the integrated technology of biochar return to the soil, the key components of the biochar discharge system applicable to the biochar return machine were designed, and the force analysis of the return shovel was carried out to obtain the main working parameters affecting the effect of biochar return. Single factor and multi factor simulation tests were conducted with the coefficient of variation of biochar content uniformity as evaluation indexes, and outlet distance, conduit diameter, baffle angle as influencing factors. The data were processed and parameters were optimized using Design-Expert, and the results were optimized and experimentally verified. The results from the experimental the coefficient of variation of biochar content uniformity and simulation data from the model showed good agreement. Therefore, the procedures of this study can be used for the integrated technology of biochar return.
