Description

Process of Propolis Extract
1. Pre select and grade raw materials to remove impurities.
2. Put the pre selected raw materials into the refrigerator at - 18 ℃for 48h.
3. Raw materials shall be crushed in crusher after freezing. It's easy to break under - 5 ℃.
4. The crushed raw materials are put into the vibrating screen (14 mesh), and the particles larger than 14 mesh are returned to the refrigerator.
5.Put the crushed and screened raw materials into the immersion kettle with reflux condenser. Add 90% ethanol [propolis (weight):ethanol (volume = 1:4)], stir for 6h at room temperature, stand for 2h, discharge the supernatant, add 90% ethanol, repeat the
above process for 3 times, and combine the solution. During the impregnation, the temperature is about 25 ℃.
6. After immersion,the solution enters the cooling reaction kettle, circulates in the adding sleeve for cooling, mechanically stirs and cools to
below 5 ℃.
7. Filter the cooled solution with a filter. When the solution temperature is less than 5 ℃, the beeswax can be separated out and filtered out with the filter residue.
8. The filtrate enters the decompression evaporator and the water bath is
heated. When the temperature is less than 50 ℃, the evaporation of volatile oil and the thermal denaturation of effective components can be reduced.
9. The evaporated ethanol vapor is recycled by the condenser and injected into the solvent storage tank for recycling.
10. After the evaporated propolis is injected into the mold, it becomes (pure propolis) commodity.
