Eucommia ulmoides extraction equipment

Medicinal Eucommia ulmoides, which is the dried bark of Eucommia ulmoides plant in the Eucommia ulmoides family, is a precious nourishing medicinal herb in China. It has a sweet taste and a warm nature. It has the effects of nourishing the liver and kidneys, strengthening muscles and bones, regulating the Chong and Ren meridians, and stabilizing the fetus. The extract of Eucommia ulmoides plant contains many impurities such as plant protein, starch, fiber, pigments, etc. Traditional plate and frame filtration cannot completely intercept impurities, and prolonged storage can cause precipitation, seriously affecting the appearance and purity of the product. The ultrafiltration membrane filtration system is a molecular level filtration with high filtration accuracy, which can remove impurities such as large molecule dissolved substances and colloids in the extract of Eucommia ulmoides, resulting in high clarity of the permeate and high product content.

The relative molecular weight of the active ingredients in Eucommia ulmoides extract is relatively small, while the relative molecular weight of the ineffective ingredients is relatively large. The use of membrane separation ultrafiltration technology can remove high molecular impurities without losing the active ingredients of the drug. Ultrafiltration membrane technology uses the principle of selective screening of membranes to intercept large molecular impurities, allowing the effective components of traditional Chinese medicine to pass through and the ineffective components of high molecular weight to be intercepted, thereby achieving the effect of clarification, impurity removal, and long-term sedimentation.

Advantages of Du Zhong extraction membrane separation technology

1. Molecular level filtration separation with high accuracy can effectively remove large molecular impurities from the extraction solution;

2. The feed liquid operates in a cross flow mode without the need for filter aids, which can solve pollution blockage;

3. Membrane separation is a pure physical process that does not undergo phase or qualitative changes, does not undergo chemical reactions, does not damage the active ingredients, and ensures product quality;

4. Replacing traditional diatomaceous earth filtration or plate and frame filtration, saving consumables and enterprise costs;

5. Automated PLC design, capable of online regeneration, cleaning, and sewage discharge, reducing labor intensity and achieving clean production;

6. The membrane system is made of 304 or 316L stainless steel material, which complies with GMP and other certifications.
