Vacuum freeze drier in the centipede medicinal materials processing technology of freeze-drying:

1, will live a centipede with water soak 5 ~ 10 hours, make its excretion as unclean, placed in the tray inside,

2, 2 ~ 5 hours put in freezer, cold storage, temperature of 2 ~ 5 ℃;

3, and then placed in the vacuum freeze drier the shelf inside the drying chamber, spread the centipede quantity is 8 ~ 10 kg/m2, opened refrigerating equipment, through the racks of freezing tube will be inside the oven temperature control for - 38 ~ - 40 ℃, the centipede freeze 2 ~ 3 hours. Open the mechanical vacuum pump, makes the pressure inside the oven for 12. 5 ~ 13. 3Pa; Open the roots vacuum pump, pressure drop to 1. 3 to 1. 33Pa; At this point to freeze the centipede the sublimation of ice into water vapor; Opening of the condenser, thermostat for - 57 ~ - 60 ℃, the water vapor in the condenser knot cream; Open the heating system, the shelf temperature from - 38 ~ - 40 ℃ slowly heated to 9 ~ 10 ℃, the process 9 ~ 13 hours. The shelf temperature slowly heated to 28 ~ 30 ℃, this process is 7 ~ 9 hours. Condenser water 65-85% of total quality, quick drying centipede;

4, sealed packaging, quick finished centipede; Or reuse mechanism of low temperature powder into powder 50 ~ 200 purpose, a quick centipede powder. The centipede powder into empty capsules, a quick freeze-drying centipede powder capsules.
