Objective: To raise the end-product and economical efficiency of spraying granulation, we demand screening preparation technique.
Method: Adopting newly spraying granulation technique, taking extracting technique, adhesive material, temperature of exit and entry,and the matching of accessories as inspecting factors, two levels of each factors, end-product as inspecting marker, we selected the best Baoshen granules preparation technique by orthogonal design.
Result: Among the 4 factors, adhesive material is most notable, next is temperature of exit and entry, the other two is of little importance.
Conclusion: The optimum spraying granulation technique of Baoshen granules is A2B1C2D1.
