1. Medicinal material pretreatment: Remove impurities (small stones, grass, clumps of dirt, etc.) from each Chinese medicinal material raw material as well as deteriorated and non-compliant raw materials (insect-damaged, moldy, etc.). Among these, Mesona chinensis (Chinese mesona) needs to be cut into small sections, and monk fruit needs to be crushed for later use. 2. Weighing: Accurately weigh each raw material (when weighing, select different measuring instruments according to the different amounts of each raw material, and they should be consistent with the measuring instruments selected for re-weighing), and store them separately in different containers for later use. Carefully keep weighing and rechecking records. 3. Rinsing: Place each medicinal material separately

Carefully keep weighing and rechecking records.

3. Rinsing: Place each medicinal material separately in a corresponding rinsing container and wash it individually with ingredient water, repeatedly rinsing until the washing water is basically clear. The storage time of each batch of medicinal materials from completion of washing to feeding must not exceed 2 hours.

4. Extraction: Add all the rinsed Chinese medicinal materials, add hot water at about XL85°C to the extraction tank, quickly raise the temperature to 100°C, maintain the boiling state for 20 minutes, then quickly draw out the medicinal liquid and cool it through a plate cooler to the standard tank. After the first discharge is completed, carry out a second decoction, add hot water at about XL85°C again, quickly raise the temperature to 100°C, maintain the boiling state for 10 minutes, then quickly draw out the medicinal liquid and cool it through a plate cooler to the standard tank.

5. Residue discharge: After the extraction tank completes discharge, empty the medicinal residue, and use filtered water to rinse clean the residual medicinal residue on parts such as the Chinese medicinal material partition plate, tank wall, and bottom cover screen (which should be cleaned with emphasis, otherwise it will affect the discharge speed of the next batch of liquid) before feeding again.

6. Centrifugation and filtration.

7. Blending: Add the corresponding syrup for the ingredients, pump in all the filtered medicinal liquid, stir evenly, and make up to volume.

8. UHT sterilization: The liquid is sterilized by UHT at 137°C for 30S.
