| titleOfInvention | A kind of drying method for preparing active collagen polypeptide from fresh pig skin |
| abstract | The invention discloses a drying method for preparing active collagen polypeptide from fresh pigskin, which comprises the following preparation steps: filling of raw materials - pre-freezing - pre-evacuating - sublimation drying - analytical drying - moisture testing; The resulting collagen peptide solution is placed in the tray inside the front box of the freeze dryer; 2. Pre-freezing: within 60 to 80 minutes, reduce the internal temperature of the tank to ‑30 degrees Celsius, and at a temperature of ‑30 degrees Celsius Continue to freeze for 4 hours; 3. Pre-evacuation: vacuum the front box of the lyophilizer for 5 minutes at a pressure of 0.1Mpa and a temperature of ‑45 degrees Celsius; 4. Sublimation drying: in a vacuum environment, at 50 to 70 Raise the temperature to 0 to 10 degrees Celsius within minutes, and continue to dry for 600 to 700 minutes at a pressure of 0.2Mpa and a temperature of 0 to 10 degrees Celsius. The internal pressure and temperature of the front box rose to 0.4Mpa and 35 degrees Celsius. |
