The invention relates to a concentration method of a gelatin traditional Chinese medicine, and particularly relates to a membrane separation concentration method of gelatin traditional Chinese medicine dilute gelatin solution. The concentration method comprises the following steps: filtering a dilute gelatin solution by a filter, centrifuging the filtered solution by a centrifuge; performing concentration separation of the centrifuged dilute gelatin solution by a membrane separation concentration device; removing foam from the gelatin solution after membrane separation concentration, further concentrating the solution by a concentration tank, and discharging the gelatin. The method of the invention has the advantages of energy saving, consumption reduction, production efficiency improvement, low noise, low labor intensity, simple equipment installation requirements, and the like when compared with conventional triple effect concentration methods.
