ABSTRACT: Objective To optimize the microwave drying parameters of apricot shellfish antitussive extract. Methods The microwave drying technology of apricot shellfish cough extract was optimized by L9 (34) orthogonal test with microwave drying equipment, drying time, tray thickness and vacuum as the optimization factors. The microwave drying technology of apricot shellfish cough extract was optimized by L9 (34) orthogonal test.
Results The optimum microwave drying technology of apricot shellfish antitussive extract was microwave power 6 kW, drying time 9 min, paving thickness 2-2.5 cm, vacuum degree_0.08-_0.09 MPa. ConclusionThe process is efficient, energy-saving, stable and feasible, and provides experimental basis for improving the drying process of Xingbei Zhike granules.
