Technological process of nine-steaming and nine-drying Polygonatum sibiricum

Study on steaming and drying technology of Jiuhua Huangjingjiu;

The production technology of Jiuhua Polygonatum sibiricum, from planting to leaving the factory, is completely in accordance with the traditional technology and is made by hand. The specific production process is as follows:

1, select Jiuhua Polygonatum, remove roots and wash.

2, a system. Put that clean Polygonatum odoratum in a pot, adding a prop amount of seasoning, boiling with strong fire, drying in the sun, and selecte again.

3. Peel and wash the selected Polygonatum sibiricum.

4, binary. Second cooking, sun and night dew, don't get wet in the rain.

Five, three to five. Boil it for three times, control the fire temperature, spread it, dry it, expose it to the sun for two nights, and then dry it.

Six, six to nine. From the sixth cooking, slow fire is the main method, and the time gradually decreases from 40 minutes. After steaming, stew for 40 minutes, take out and dry, and expose to the sun until it is 80% dry.

7. From the first line to the ninth line, the color of Polygonatum sibiricum changed from yellow to brown, with sweet taste and no astringency. At this point, the production of Jiuhua Polygonatum was completed.
