Abstract

The invention relates to a pretreatment method for traditional Chinese medicine donkey-hide gelatin's bulk drug donkey hide. The method provided by the invention comprises: 1) washing; 2) fleshing; and 3) toggling drying. The method provided by the invention adopts an improved toggling drying process to replace the traditional drying step, and setting the water content of the donkey hide subjected to toggling drying treatment in a most appropriate range, within a certain range of temperature, drying the hide and simultaneously fixing the hide during toggling drying to avoid natural shrinkage of the hide, thus facilitating fast drying of the donkey hide. The hide can be smoother, the whole drying process does not exceed 24h, and the drying efficiency is improved. In addition, the method provided by the invention is also added with cooling washing and mechanical fleshing, blood stain, silt and grease on the hide are effectively removed, and breeding of bacteria is reduced, thus being conducive to long-term preservation of the donkey hide. The method provided by the invention has high drying efficiency, the hide moisture uniformity is good, the energy consumption is low, the hide is clean, and the quality is stable, thus guaranteeing quality homogeneity of donkey-hide gelatin from the source.

Description

technical field [0001] The invention relates to a pretreatment method of donkey-hide gelatin as a raw material of traditional Chinese medicine, in particular to a pretreatment method of donkey skin dried on a stretcher board. Background technique [0002] Donkey-hide gelatin is a traditional traditional Chinese medicine with a long history. Its main raw material is donkey skin, and the quality of donkey-hide skin is the most important factor affecting the quality of donkey-hide gelatin. The donkey skins used to make donkey-hide gelatin mainly come from the skins peeled off from the animals after slaughtering equine animal donkeys. Due to reasons such as breeding, slaughter, and transportation, there is usually an interval between the fresh donkey skins being peeled off from the animals and the processing of donkey-hide gelatin. For a certain period of time, if the fresh donkey hide is not preserved in any way during this period of time, since there are many types of proteins...
