Pig gall powder preparing process

The invention discloses a pig gall powder preparing process. The process comprises the steps that pig bile is fetched and conveyed into a first drying device, and steam is led into the first drying device to heat the pig bile to 50-70 DEG C; the air pressure in the first drying device is adjusted to be lower than the atmospheric pressure for drying under reduced pressure; when the relative density of materials reaches 0.8-1.25, the pig bile is cooled down to below 30 DEG C, the materials are taken out, placed into a heated air circulation constant-temperature drying oven for drying at the temperature ranging from 40 DEG C to 70 DEG C with the traying thickness ranging from 1 cm to 2 cm, smashed and filtered through a screen with the mesh ranging from 80 to 100 to obtain pig gall powder medicinal slices, and then the pig gall powder medicinal slices are packaged into finished products. Pig gall powder prepared from the pig bile is excellent in quality, and the major component of the pig gall powder is taurohyodeoxycholic acid sodium hydrate which has the effects of clearing heat, moistening dryness, relieving cough and asthma and detoxifying; the pig gall powder is rich in cholanic acid, can effectively inhibit forming of bile acid, dissolve fat and reduce cholesterol and triglyceride in blood and has a good curative effect on various types of hyperlipemia.
