Industrial Supercritical CO₂ Extraction Equipment & Systems
TOPTION brand Supercritical Fluid Extraction Machine is also named Essence Extraction Machine, which is used for the extraction of material (solid or liquid) under high pressure and suitable temperature extraction. By changing conditions in the separation kettle, the dissolved substances will resolve in order to achieve the purpose of separation.
TOPTION provides configurable industrial supercritical CO₂ extraction systems designed for high-pressure processing of botanical, pharmaceutical, and chemical feedstocks. Our TOP320 series features a three-extractor, two-separator circulation design, optimized for continuous-duty cycles and precise control of pressure and temperature.

Key Features: Precision, Selectivity, and Sustainability
1. The extractor is equipped with a quick opening, the quick opening mechanism adopts a special design (the technology introduced from the 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, and the appearance is beautiful.
6. Equipment has reliable security: in addition to the pressure device having enough safety margin, the extractor, separator, and evaporator are equipped with a safety relief valve, and the CO₂ pump discharge has pressure-limited protection, the whole unit will stop running while over pressure.
7. Control system operation is simple: extraction and separation pressure, heating and cooling temperature, and CO₂flow can be determined by process.
8. Use a frequency converter to adjust CO₂ flow, which is convenient for process and energy saving.
