Abstract: Objective： Through the intelligent TCM pharmacy platform system， to determine the water absorption coefficient of each herbal in fanggan prescription and improve the modern automatic decocting efficiency. Methods： To study on the water absorption of each herbal in fanggan prescription， by weighing and calculateing the water absorption coefficient of immersion， decoction and extrusion of each herbal. Compared the liquid volume difference of water absorption coefficient of each herbal， 1.5 mean water absorption coefficient and artificial experience operation after decocting， so that determine the suitable method for water addition. Results： The error range of actual volume of liquid obtained from water absorption coefficient of each herbal was small. In traditional decocting， the error range of the artificial water addition for the liquid obtained is 17.33%-29.33%， with an average of 22.36%， but the error range of liquid volume obtained from automatic decoction water absorption coefficient of each herbal is 0.67%-4.00%， with an average of 2.37%. In modern decocting， the error range of liquid volume obtained from 1.5 mean value is 1.21%-6.75%， with an average of 4.29%， but the error range of liquid volume obtained from automatic decoction water absorption coefficient of each herbal is 0.63%-1.88%，with an average of 1.16%. Through the reserve calculation， the error range of water addition of 1.5 mean value is 0.12%-8.16%， with an average of 5.15%， but the error range of water addition of automatic decoction water absorption coefficient of each herbal is 0.02%-2.86%，with an average of 1.09%. Conclusion： The water absorption coefficient of fanggan decoction applied in calculating water addition is better than artificial water addition and 1.5 mean value water addition， and can be used to guide the automatic water addition of fanggan decoction and improve the decoction efficiency.
