Purpose:To investigate the effect of different inlet air humidity on the boiling granulation efficiency of Chinese herbs with different viscosity and hygroscopicity.Methods:The contents were investigated,including air inlet humidity,the granulation efficiency,particle size qualification rate and particle moisture.Results:The results showed that the inlet air humidity should be low rather than high for the material with high viscosity and hygroscopicity.For materials with small viscosity and weak hygroscopicity,the air inlet humidity should be high rather than low.Conclusion:It is suggested installing a device to adjust the air humidity in the boiling granulator to meet the requirements of different kinds of granulator.
