Factory advantage

1. Complete and perfect equipment configuration:

1) For the reason that the soaking process involved, the amount of solvent in the production process is huge, and the workshop is equipped with an ethanol distillation recycling tower;

2) Six 6500-liter stainless steel refiner reactors, four 6500-liter enamel reactors;

3) Two 30-meter fully automatic countercurrent dissolution production lines;

4) As there is huge amount of steam involved in the distillation and a large amount of solvent recycling, the factory uses the steam uniformly distributed from the industrial park (normal steam pressure is 8 kg, which is 8 atmospheres), and the factory owned boiler is used in a small amount;

2. Cost advantages:

the origin of medicinal materials for the low purchase price

3. Huge Scale Production Workshop:

For the extraction of berberine, the factory owns 5,000 square meters infiltrating warehouses with the capacity to soak 80 tons of raw material one-time. When the raw materials are soaked until the bark is white (when the target product of berberine is fully dissolved in a solvent, usually ethanol, the original bark turning white means sufficient soaked), the soak liquid is concentrated, refined and purified, and dried (it can be delivered in the form of powder or not in the form of powder, up to the buyer’s request) to obtain the finished berberine.

4. Quality advantages:

The content difference between titrametric method and HPLC inspection is small. The content of palmatine and jatrorrhizine meets the standards of the Chinese Pharmacopoeia 2015, and the heavy metals meet the standard for export.
