C, complete: adopt steam to complete the stringy stonecrop section after fermentation, steam beating temperature is 130-150 ℃, and fixation time is 2-3min, the heat radiation of spreading for cooling immediately after completing;
D, freezing: by the stringy stonecrop section after completing under-16 ~-12 ℃ of conditions, freezing 6-8 hour;
E, dry: the stringy stonecrop section after freezing is pressed to 8-10kg/m in useful load
2, operating pressure 40-60Pa, resolve under the condition of pressure 20-30 Pa, temperature 40-45 ℃ dryly, adopt the method for lyophilization, reduced the destruction to nutritional labeling, fully retain the nutriment in raw material;
F, pulverizing: dried stringy stonecrop section is pulverized, and particle diameter is 80-100um, makes stringy stonecrop powder;
G, sterilization are dried: the stringy stonecrop powder layering after pulverizing is put into baking box, and temperature is 80-90 ℃, and then time 15-20min cools the temperature to 50-60 ℃, and low temperature drying lower than 8%, makes stringy stonecrop gross tea to water content;
H, refining: by the impurity elimination of stringy stonecrop gross tea stalk-sorting, stringy stonecrop gross tea is carried out to classification, make stringy stonecrop tea;
I, packing: the stringy stonecrop tea after classification is packed with food-grade packaging material, entered in aeration-drying environment and store.
Beneficial effect: adopt stringy stonecrop tea that this method makes take the stringy stonecrop of originating widely as raw material, not only reduce production cost, and improve the economic worth of stringy stonecrop, adopt the method for lyophilization, reduce the loss of nutriment, improved 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.
