1. Brief Introduction of Supercritical Fluid Extraction Device
The technique of super critical fluid extraction (SCFE or SFE) is a new type green separating technique with wide adaptability, which is rising in the modern world. with this technique, during the extraction process. no chemical agent is needed; no pollution is done to the separated substance, so as to fully meet the people's green requirements to medicine, food, health products, and cosmetics Also, this technique boasts the feature of high extraction effect, high quality, low extraction temperature, low energy consumption. And without pollution, especially suitable for the extraction of heat-sensitive and active substances. This device can extract widely volatile oil, alkaloid, and phenol and other medical elements from animals and plans.
Wenzhou Chendong Medicine machine Co., Ltd. with the technical advantage of the chemical industry department and Zhejiang university, and combined our own manufacturing experience in making high pressure equipments, designed the supercritical fluid equipment, which at present is of first-rate at home and abroad.
2. The main technical data of this equipment is as follows:
(1).The highest extraction pressure can reach 40mpa, the extraction temperature of indoor, he separating, distillation temperature are all 80?? indoors. The clients can adjust the above data.
(2).Design or making of one pot of several extraction pots, different combination of separating pots for extracting fluid and other material.
(3).Non-standard extraction and separating pots, are of compact structure, easy to use. Equipped with strong anti-fatigue strength, it's safe to use. Large equipments are fitted with safety chain device.
(4). Samples can be obtained on line and the fluid of each extraction pot and separation pot can be circulated and a flow meter to show the circulating volume.
(5). Temperature is shown by automatic numerical control system, which is easy to use and control. Pressure safety devices are fitted with safety valves and anti explosion pieces. Add high safety coefficient. If necessary, computer control system can be provided.
(6). The whole equipments are made of stainless steel. attractive and durable. they are the ideal equipments in the food and medicinal industries. The technique of making some relevant agents will also be attached.
3. Characteristics of the Supercritical CO2 Extraction Device
Low critical temperature, and it is suitable for extraction and purification of heat sensitive compound. Being capable to provide inert environment to avoid oxidation of products and affection of effective content of extracts. Fast extraction speed, no toxicity, non-flammable, safe application and no pollution upon environment. No residue of solvent, no nitrate and ions of heavy metal. The press ring of the extraction kettle can be opened quickly; O-ring is imported with service period over 4 months. CO2 can be used in circulation. It can be designed and manufactured as per "GMP" standard. The pressure stabilizing system of the extraction kettle is imported back-pressure valve. It can be matched with computerized automatic control system (temperature, pressure, flow). All valves of the device are under special heat treatment so they are robust and durable.
