Different substances have their own sublimation temperature range, setting sublimation temperature and sublimation holding time. The Lyophilization Equipmentand holding time of the sample should be set according to the required water content of the freeze-dried substance. Work until freeze drying is over. According to the established temperature and holding time, a Lyophilization curve of freeze-drying temperature and time is established, and the freeze-drying curve is the relationship curve between the temperature and time of the freeze-drying oven laminate. With temperature as ordinate and time as abscissa. It directly reflects the change of laminate temperature at different times during the drying process. Generally, leafy vegetables are Lyophilization . Different experimental samples have different requirements for... less
