Best tea polyphenol solvent extraction machine
2026-03-26
Tea polyphenols are hailed as "natural antioxidants" and are widely utilized across the food, pharmaceutical, and health supplement industries. However, traditional extraction processes face numerous challenges: low extraction efficiency, high solvent consumption, susceptibility of active ingredients to degradation, and it is difficulty in achieving large-scale production due to equipment limitation. Faced with surging market demand and mounting environmental pressures, how can high-purity tea polyphenols be obtained efficiently and cost-effectively?
To make the competitive of the tea polyphenols that is high extraction efficiency and purity. The principle of solvent extraction utilizing the differential solubility of various compounds found in tea leaves across different solvents to achieve extraction and separation.Process Flow: Tea Leaves → Boiling Water Extraction → Filtration → Filtrate → Chloroform Extraction → Ethyl Acetate Extraction → Concentration & Drying → Crude GTP.
Centrifugal extractors utilize the centrifugal force generated by high-speed rotation to accelerate the mixing and separation of liquid-liquid two-phase systems. The core process：
Pre-treatment and Extraction: After the tea leaves undergo crushing and alkalization treatments, the tea polyphenols dissolve into the aqueous extract;PH Adjustment and Solvent Extraction: The pH level is adjusted to liberate the tea polyphenols (converting them to their free form); solvents such as diethyl ether or ethyl acetate are then employed for extraction, facilitating the rapid transfer of the tea polyphenols into the solvent phase;Purification and Crystallization: The solvent phase undergoes steps such as concentration and drying to ultimately yield high-purity tea polyphenols. Compared to traditional hot water extraction methods, centrifugal extraction technology can reduce the extraction cycle by over 50% while simultaneously cutting solvent consumption by 30%.Advantages of Centrifugal Extraction Technology✔ High Efficiency and Energy Savings: The Preferred Choice for Industrialization
✔ The equipment supports continuous operation, with a single unit capable of processing several tons per day, thereby meeting the demands of large-scale production;
✔ Centrifugal force accelerates the mass transfer process, boosting extraction efficiency by over 40%; furthermore, solvents can be recycled, leading to a reduction in overall operational costs.
✔ Zero Damage to Active Ingredients
✔ Extraction is conducted at ambient temperatures, avoiding the high-temperature degradation that can compromise the structural integrity of tea polyphenols and ensuring the preservation of their antioxidant activity;
✔ The enclosed system design minimizes the risk of oxidation, allowing for the production of tea polyphenols with a purity level exceeding 98%. Strong Environmental Compatibility
✔ Solvent recovery rates exceed 90%, thereby reducing wastewater discharge and environmental pollution.
Compared to ion precipitation (which requires heavy metal salts) and column separation (which entails high consumable costs), solvent extraction aligns more closely with the trends of green manufacturing.Various application of solvent extration centrifugal extractor(1) Fine Chemicals: Two-phase separation following synthesis reactions, acid washing, alkali washing, water washing, etc.
