About our supercritical CO2 extraction equipment

Our supercritical CO2 extraction equipment uses CO2 as an additive and is mainly used for the extraction and fine separation of effective ingredients such as medicine, food, flavors, and spices. The device is composed of an extraction kettle, a separation kettle, a rectification column, a CO2 pump, etc.: the extraction kettle is 0.5-50L/32-50Mpa for solid-liquid dual-use, and CO2 is used in a cycle. Containers, valves, and pipelines in contact with fluid are made of 1Cr18Ni9Ti stainless steel.

Advantages of our supercritical CO2 extraction equipment

Our company and Shanghai Jiaotong University have conducted in-depth research on the safety interlocking of the extraction kettle opening mechanism, fluid control technology, intelligent PLC and DCS control technology, and intelligent high-pressure control valve, fully combining the company’s equipment manufacturing experience and the design advantages of Shanghai Jiaotong University. The supercritical CO2 extraction equipment has achieved a qualitative leap in automation, ease of operation, and production safety.

Our company has successfully developed domestic fully automatic and intelligent supercritical CO2 extraction equipment, which realizes automatic control of extraction pressure and temperature, automatic isobaric switching of extraction pressure, automatic recovery and utilization of carbon dioxide gas, the quick-opening structure of the extraction kettle clamp and safety linkage The lock mechanism and other functions have filled the domestic gap.

About us the professional supercritical CO2 extraction equipment manufacturer and exporter

Since 1989, under the care and guidance of experts and scholars from Tsinghua University, the Chinese Academy of Sciences, universities and colleges, the main focus has been on the localized development and production of supercritical CO2 extraction equipment. For more than 20 years, a series of small and medium-sized and large capacity supercritical CO2 extraction equipment have been formed. Our supercritical CO2 extraction equipment have been appreciated and recognized by customers all over the country, and we have exported supercritical CO2 extraction system the to the United States, South Korea, Southeast Asia and other countries. The new drugs produced by some pharmaceutical factories through our supercritical CO2 extraction equipment have been approved and exported.

Our supercritical CO2 extraction equipment has passed the provincial appraisal, and its main technical indicators and key equipment have reached the advanced level of similar devices in the world. The project has been included in the Torch Plan and new products, and the company has been assessed as a high-tech enterprise in Jiangsu Province and an honest tax-paying enterprise in Nantong City. The company has a strong technical force, sophisticated equipment, advanced technology and complete testing methods. The company’s laboratory is equipped with prototypes for users and scientific research units to come to the company for joint development and research.

Benefits of Supercritical CO2 Extraction

By using supercritical CO2, the producer has total control over the procedure, CO2 can be recycled, making this method more environmentally friendly compared to others. Further, the Federal Drug Administration (FDA) has labeled CO2 safe for industrial extractions. CO2 acts as a cleaning agent, so microbial bacteria, molds, and mildews are killed during the process. The yield using supercritical CO2 is higher than other extraction methods; however, the yield and quality of product can easily be varied by adjusting the physical properties.
If there is residue on the extract, it will evaporate, as CO2 is a gas at room temperature. Extracts obtained from supercritical CO2 extraction are appealing to the food and beverage and medical industries, because it is guaranteed there is no residual solvent present on the product. Because there is no residual solvent on the product, the extract will be purer than many solvent-based extraction methods. Additionally, the plant is not subjected to extreme temperatures, so it does not experience degradation as it does during other extraction methods.
