Precautions for the Production Process of Inorganic Ceramic Membrane Filter in the Refining Process of Traditional Chinese Herbal Extract

The ingredients contained in the extract of traditional Chinese medicine are very complicated, and they have a variety of active ingredients, ineffective ingredients, and also contain toxic ingredients. The use of inorganic ceramic membrane to purify the traditional Chinese medicine extract to further separate and purify the active ingredient, and obtain the effective monomer is an important content in the refined production process of the traditional Chinese medicine extract. That is to maximize the extraction of the active ingredients, so that the intrinsic quality and therapeutic effect of the traditional Chinese medicine extract is improved, so that the effect of the Chinese medicine extract can be maximized. Inorganic ceramic membrane filter is used in the whole production process of traditional Chinese medicine extract. In order to ensure product quality and equipment safety, only each technical processing link in the production process should be considered in detail, pay attention to the extraction, crude and refining every step of the processing process of traditional Chinese medicine extract, pay attention to the cleaning of the inorganic ceramic membrane system and avoid incomplete cleaning and cross-contamination. Only in this way can the inorganic ceramic membrane filter be protected, the service life of the equipment can be prolonged, the production can be carried out normally, and the quality of the Chinese medicine extract can be ensured.

Before the extraction of Chinese herbal medicines, the preparation of Chinese herbal medicines should be done in order to remove the sediment and fibers from the Chinese herbal medicines before extraction. In the operation process before and after the extraction of Chinese herbal medicines, the extraction time, extraction temperature, extraction water addition and other parameters should be strictly controlled to avoid excessive extraction time and excessive extraction temperature, resulting in a large number of invalid analysis.

After the extraction of Chinese herbal medicines, the Chinese medicine extract is centrifuged using a tube centrifuge, or other methods are used to remove a large amount of ineffective components in the Chinese medicine extract.

Before using the inorganic ceramic membrane filter to refine the traditional Chinese medicine extract, firstly reduce the temperature of the traditional Chinese medicine extract. The temperature range should be controlled at 15 to 20 °C, and the temperature will decrease. The impurities in the Chinese medicine extract will be precipitated.

The inorganic ceramic membrane filter is cleaned with purified water or water for injection before use to remove impurities such as oils, proteins and other organic substances and colloidal substances on the surface of the inorganic ceramic membrane and the system. The inorganic ceramic membrane filter should be cleaned with a special cleaning agent or 0.2% sodium hydroxide solution after use to maximize the recovery of the inorganic ceramic membrane flux and avoid cross-contamination.
