Example Embodiment
[0100] Example 1: Preparation of bear bile powder
[0101] (1) Filter the bear bile collected by the tubeless drainage method to obtain the filtrate, and dilute it with 0.75 times the amount of water to obtain the bear bile liquid. Let it stand for 12 hours at a temperature of 2-6°C, and then perform subsequent operations;
[0102] (2) Fill the bear bile liquid obtained in step (1) with nitrogen gas for 27 minutes and then carbon dioxide for 18 minutes by means of bubbling;
[0103] (3) Pour the bear bile liquid treated by the above operation into the material tray (liquid layer depth 1.5 ~ 2.5cm), immediately put it in a freeze dryer pre-frozen to -50 ℃, freeze for 3.5 hours; then Raise the temperature to -22°C at a rate of 0.3°C and hold for 1 hour; then raise the temperature to -3°C at a rate of 0.3°C per minute and hold for 2.5 hours; then heat up to 10°C at a rate of 0.3°C per minute and hold for 4.5 hours; then Raise the temperature to 32°C at a rate of 0.3°C per minute and ke...

[0111] Example 2: Preparation of bear bile powder
[0112] (1) Filter the bear bile collected by the tubeless drainage method to obtain the filtrate, and dilute it with 0.5 times the amount of water to obtain the bear bile liquid. Let it stand for 12 hours at a temperature of 2 to 6°C, and then perform subsequent operations;
[0113] (2) Fill the bear bile liquid obtained in step (1) with nitrogen for 30 minutes and then carbon dioxide for 15 minutes by means of bubbling;
[0114] (3) Pour the bear bile liquid treated by the above operation into the material tray (liquid layer depth 1.5 ~ 2.5cm), immediately put it in a freeze dryer pre-frozen to -55 ℃, freeze for 3 hours; then every minute Increase the temperature to -23°C at a rate of 0.3°C and hold for 1.5 hours; then increase the temperature to -2°C at a rate of 0.25°C per minute and hold for 2 hours; then increase the temperature to 12°C at a rate of 0.25°C per minute and hold for 5 hours; then Increase the temperature to 30°C...

[0122] Example 3: Preparation of bear bile powder
[0123] (1) Filter the bear bile collected by the tubeless drainage method to obtain the filtrate, dilute with 1 times the amount of water to obtain the bear bile liquid, and let it stand for 12 hours at a temperature of 2-6°C before proceeding with subsequent operations;
[0124] (2) Fill the bear bile liquid obtained in step (1) with nitrogen gas for 25 minutes and then carbon dioxide for 20 minutes by means of bubbling;
[0125] (3) Pour the bear bile liquid processed by the above operation into the material tray (liquid layer depth 1.5 ~ 2.5cm), immediately put it in a freeze dryer pre-frozen to -45 ℃, freeze for 4 hours; then every minute Increase the temperature to -20°C at a rate of 0.35°C and hold for 1.2 hours; then increase the temperature to -2°C at a rate of 0.35°C per minute and hold for 3 hours; then increase the temperature to 15°C at a rate of 0.34°C per minute and hold for 4 hours; then Increase the temperature to ...
