[0033] The solutions obtained in Examples 1 to 3 were freeze-dried according to the following method to prepare various trace element freeze-dried powder preparations of the present invention:
[0034] Pre-freezing: Reduce the temperature in the freeze-drying box to about -20°C, -25°C, and -35°C in advance, and put the subpackaged solution to be freeze-dried on the inner partition of the freeze-drying box for pre-freezing.
[0035] Sublimation drying: raise the vacuum in the freeze-drying box to below 13.33Pa (0.1mmHg column), and turn off the freezer. Slowly heat through the heating system under the partition, and properly heat the partition to about 10°C to supply the heat required for the sublimation of ice. The temperature of the condenser drops below -30°C, and sublimation and drying are carried out for 15, 11, and 13 hours. .
[0036] Re-drying: Control the drying temperature at 20°C, 30°C, and 10°C respectively, and control the plate temperature below 30°C until the pr...
