Embodiment Construction

[0015] 1. Vacuum freeze-drying of cloth dregs leaves is carried out by vacuum freeze dryer.

[0016] Select fresh cloth dregs leaf raw materials, remove impurities such as branches, inferior quality and dead leaves, and rinse quickly; pre-dry the cloth dregs leaves to a water content of 70%; put the pre-dried cloth dregs leaves on a plate, and the weight of the plate is 3.1 kg / m2, thickness 2.5cm, pre-freeze at -18℃~-38℃ after gradually cooling down for 3 to 4 hours; then vacuumize until the absolute pressure of the system is 110Pa, enter the heating program, maintain the vacuum degree at 50~60Pa, and raise the temperature of the shed To 60°C, sublimation drying for 16 hours; then keep the temperature of the material at 30°C, make the water content below 1.8%, and then discharge.

[0017] After the above-mentioned process steps, the cloth dregs leaves are ground into powder and passed through a 120-mesh sieve for physical wall breaking. In a sealed and dry state, two supersoni...
