High quality simple process mixture supercritical black tea extract
Supercritical Fluid Extraction is a kind of high and new separation technology which developed nearly 10 years, it has difference with conventional solvent extraction which use organic solvent, the new one choose a substance called Supercritical Fluid (SF) as extracting agent instead of organic solvent. Supercritical fluid is a substance that exists in a fluid form at the critical temperature and critical pressure.This fluid have the dual nature of liquid and gas at the same time, the composition has a strong ability to dissolve many extraction. The solute separated as the change of pressure and temperature and the solubility will happen obvious changes, and CO2 is the most commonly used extraction agent.
1. It can be extracted at near normal temperature without destroying biological active substances, especially suitable for the separation, extraction of heat-sensitive and easily oxidized substances.
2. The extract has no residual solvent, so it is called "100% natural".
3. Extraction process parameters are easy to adjust and control, and the products have high yield.
4. Little extraction procedure, simple process, high efficiency and low energy consumption.
5. CO2 is cheap and easy to use, non-toxic and tasteless, not producing "three wastes", pollution-free and "environmentally friendly".
In the early 1990s, the company was committed to the research and development and design of supercritical extraction equipment, and constantly improved and improved, gradually forming its own equipment characteristics.
1.The extractor is equipped with a quick opening, the quick opening mechanism adopts special design (the technology introduced from US), and the switch kettle is portable and fast.
2. The extractor and separator are made of stainless steel integral forgings with high strength and long life.
3. Unique cylinder design, which increases the effective contact with the material in the extractor, overcomes the "bypass" phenomenon of CO2, improves the extraction efficiency and yield, and reduces the extraction time.
4. The heat exchange system is equipped with electric heating device. The temperature can be set arbitrarily and the heating is stable and uniform.
5. Adopt the refrigeration unit of joint venture technology, the refrigeration effect is good, the appearance is beautiful.
6. Equipment has reliable security: in addition to the pressure device has enough safety margin, the extractor, separator, evaporator are equipped with safety relief valve, and CO2 pump discharge has pressure limited protection, the whole units will stop running while over pressure.
7. Control system operation is simple: extraction and separation pressure, heating and cooling temperature, CO2 flow can be determined by process.Computer centralized control, 17 inches color LCD touch screen display and control, high speed, high performance microprocessor, cooperate with the company self-developed software can realize multi-channel signals at the same time of test, record, display, alarm and control output, and has USB interface, can be inserted U disk backup history data, or connect printer to print history curve and data.
8. Use frequency converter to adjust CO2 flow, which is convenient for process and energy saving.
