Orthogonal experiments to select spraying granulation technique for Baoshen granules / 中国中药杂志

<p><b>OBJECTIVE</b>To raise the end-product and economical efficiency of spraying granulation, we demand screening preparation technique.</p><p><b>METHOD</b>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.</p><p><b>RESULT</b>Among the 4 factors, adhesive material is most notable, next is temperature of exit and entry, the other two is of little importance.</p><p><b>CONCLUSION</b>The optimum spraying granulation technique of Baoshen granules is A2B1C2D1.</p>
