The present invention provides a kind of method of infra-red drying method preparation chitosan biological gel mould, and the present invention comprises the following steps：Chitosan and acetic acid solution are put into beaker, glycerol is added in heating water bath stirring after completely dissolution, is uniformly cast in glass mold after being sufficiently mixed after ultrasonic vibration deaeration and is put into drying in infrared drying oven.Mixed solution is prepared using chitosan and Geniposide as raw material, by ultrasonic vibration deaeration, infrared drying processing, obtains properties preferably biogel film, and substantially reduce the production cycle of chitosan biological gel mould.The preparation method carries out cross-linking reaction using Geniposide and chitosan according to a certain percentage, and is modified with glycerol, and reaction is mild, environmentally protective.Compared with traditional steam drying, infrared drying of the invention is high-efficient, easy temperature control system, and heating rapidly, can be energy saving, highly-safe. |
