D, freezing: by the stringy stonecrop section after completing under-16 ~-12 DEG C of conditions, freezing 6-8 hour;
E, drying: the stringy stonecrop section after freezing is pressed 8-10kg/m in useful load
2, operating pressure 40-60Pa, resolve pressure 20-30 Pa, temperature 40-45 DEG C condition under dry, adopt the method for lyophilization, reduce the destruction to nutritional labeling, fully retain the nutriment in raw material;
F, pulverizing: dried stringy stonecrop section pulverized, particle diameter is 80-100um, obtained stringy stonecrop powder;
G, sterilization are dried: baking box is put in the stringy stonecrop powder layering after pulverizing, and temperature is 80-90 DEG C, and time 15-20min, then cools the temperature to 50-60 DEG C, and low temperature drying lower than 8%, obtains stringy stonecrop gross tea to water content;
H, refining: by the impurity elimination of stringy stonecrop gross tea stalk-sorting, classification to be carried out to stringy stonecrop gross tea, obtained stringy stonecrop tea;
I, packaging: the stringy stonecrop tea after classification is packed with food-grade packaging material, enters in aeration-drying environment and store.
Beneficial effect: adopt this method make stringy stonecrop tea with originate widely stringy stonecrop for raw material, not only reduce production cost, and also improve the economic worth of stringy stonecrop, adopt the method for lyophilization, decrease the loss of nutriment, improve the utilization rate of raw material, becoming to sample tea also has the health-care efficacy such as clearing heat and promoting diuresis, removing toxicity for detumescence.
