The invention discloses a preparation method of dried animal original casing, comprising the following steps: dissolving, adding separation resin, extracting glue solution, separating casing glue, extruding, cooling, squeezing and drying. The preparation method of the dried animal original casing of the invention adds a large amount of casing trimmings generated in the process of making finished casings into a high-temperature pot, mixes and reacts with other colloids, and carries out a new casing production procedure. On the one hand, the raw material utilization rate is improved; on the other hand, compared with casings produced by the original trimming utilization method, the casings produced by the method have the advantages of consistent length, uniform thickness, and independence from weather conditions. In addition, the method has simple procedures, low requirements for production technology, is easy to implement, and can produce high economic and social benefits.
