How to get isatis root granule?

Banlangen granules

The purpose is to provide a production process of Banlangen granules, which improves the extraction of traditional alcohol precipitation method, retains more effective ingredients, greatly improves the yield, and reduces the generation of residual particles.

A production process of Banlangen granules. The formula of Banlangen granules is: 10-20 parts of Banlangen extract, 50-75 parts of sucrose, and 10-35 parts of dextrin.

Making Banlangen Granules includes the following steps

S1、Preparation of Isatis root extract

Wash the Radix isatidis, add water and ethanol solution to soak. After the filtrate was concentrated, the first extraction paste was obtained; decoct the filter residue, and concentrate the filtered filtrate to obtain the second extraction paste. Combine the two extraction pastes and mix evenly get Radix isatidis extract.

S2、Crushing of cane sugar

Weight and crush the cane sugar, then sift it for later use

S3、Granulating

Preparation of soft material: Add dextrin and sucrose powder into a trough mixer for dry mixing, then add Radix isatidis extract and wet mix to obtain soft material.

Wet granule preparation: turn on the oscillating granulator to preheat, and transport the soft material to the oscillating granulator to make wet granules.

Boiling dryer: transport the prepared wet granules to a boiling dryer, ventilate hot air, the wet granules are boiled and dried to obtain crude isatis granules.

S4、Sifting

Step S3 produced the coarse isatis root particles from one end of the boiling dryer and then into a double-layer vibrating screen, after screening through two layers of screen to get isatis root particles.
