CO2 supply system

Put liquid CO2 by delivery pump to condenser before or during operation. The CO2 supply system contains: outside CO2 delivery pump, outside tank.

Extraction and separation

The liquid CO2 flow through pre-heater to heat after pump by CO2 high pressure pump, then flow to extractor, the outlet temperature will be controlled automatic.

CO2 circulation system

The CO2 will back to middle storage tank after finish extraction, waiting the pressure balance between extractor and middle tank at 50bar, then put the left CO2 of extractor to the next extractor

Clean system working

Pump the clean agent to pipes from clean tank when finish extraction working.The clean system is composed of clean storage tank, clean pump.

Cold water circulation system

Pump tap water to purified water equipment, it flows to cold water tank after purifying. Pump cold purified water to refrigerator, the water will back to cold water tank after cooling.Hot water circulation system

Put soften water to hot water tank, start hot water circulation pump and heated by electro-boiler(or heated by vapor), then distribute the hot water to extractor, separator, heat exchanger by the use of hot water circulation pump.

Steel platform description

The steel platform is for device fix and operation.With carbon steel, and antirust paint, the plane and stair is stainless steel riffled plate.

Tail gas recovery system

When extraction finish, close CO2 high pressure pump, the CO2 of extractor and separator will flow back to middle tank, when pressure balance, let the CO2 of extractor to another extractor, and pump the residual CO2 by compressor when pressure balance between two extractors.

Control system description

The control system is composed of low voltage switch box, PLC control cabinet, extractor quick-open chain control cabinet, control computer, cooling unit control cabinet, and so on.

Convenient in operation. Can be used widely.

With an excellent optional function. Extracts can be gained optionally by controlling the pressure and temperature.

Low operation temperature. Can be extracted near to the room temperature, especially fit for the extracting of thermo-sensitive elements. The possibility of oxidation when contact with oxygen and reaction when meet rays are eliminated. The natural flavor of the extracts can be kept.

Extracting media and extracts can be separated easily. No leftover of CO2 on the extracts after extracting operation.

CO2 is a nontoxic, flavorless, noncombustible and cheap compound and can be recycle used.
