Supercritical co2 extraction machine, is fully automatic control equipment. The extraction, rectification tower, separation pressure and temperature are automatically controlled and the parameters can be remotely monitored by computer. The series and parallel operation of the valves between the extraction kettles are manually controlled. The maximum working pressure is controlled by a four-fold method of pressure detection sensor, safety valve and control signal interlocking, which is safe and reliable.

The extraction kettle cover of this supercritical co2 extraction machine, adopts a clamp-type hydraulic automatic quick-opening structure. All the inner walls, pipes, and fittings of the equipment that are in contact with the material are made of stainless steel with acid and alkali resistance and suitable for food hygiene requirements. The medium CO2 during the extraction process of the equipment Recyclable, maximizing the use of CO2.

The design pressure of this device is 350 bar and the maximum working pressure is 320 bar. In the whole process of designing, manufacturing, inspecting, installing and debugging the equipment, strictly implement the requirements of the current and effective Chinese relevant standards and regulations.

All the containers and pipes of this supercritical fluid extraction machine are insulated by rubber-plastic foam material, and are covered with stainless steel sheets.

Equipment composition:

The supercritical co2 extraction machine consists of a CO2 filling system, an extraction and separation system, a rectification column system, a CO2 circulation system, a cleaning system, a carrier agent system, a chilled water circulation system, a hot water circulation system, a rack platform, a control system, and an exhaust gas recovery system. .

CO2 supply system:

Before or during the operation of the equipment, liquid CO2 is injected into the precooler from an outdoor storage tank through a low-temperature CO2 transfer pump. CO2 filling system mainly includes: outdoor CO2 delivery pump, outdoor storage tank.

 Extraction and separation systems:

The liquid CO2 is pressurized to the extraction pressure by a CO2 high-pressure pump, flows through the preheater, the outlet temperature is automatically controlled, and flows to the extraction kettle after heating the phase change.

The material basket of the extraction kettle is filled with raw materials, and the electric kettle is hoisted into the extraction kettle. In the process of pure supercritical CO2 entering from the bottom of the extraction kettle and passing through the material barrel to the top of the extraction kettle, CO2 dissolves to extract the effective components in the raw material.

The extraction section contains three extraction kettles. The three extraction kettles can be used in parallel or in series.

The sealing plug of the extraction kettle is made of PTFE + stainless steel spring sealing ring (without plasticizer) that meets the standards of medicines and foods. It can be opened after depressurization and durable.

The CO2 is entrained into the separation unit with the extracted stream. The separation is performed in two steps.

The CO2 entrained with the extract flows from the extractor through the first control valve to the primary separator. Through the throttling control of the control valve, some extraction components are resolved by the pressure drop in the primary separator, and the separator can be received from the bottom of the primary separator.

The CO2 entrained with the incompletely separated extract flows through the pipeline to the secondary separator. Through the throttling control of the control valve, the low-pressure extraction component is separated and resolved in the secondary separator, and can be separated from the bottom of the secondary separator Thing.

Extraction and separation system includes: CO2 high pressure pump, extraction heater, extraction kettle (including quick opening device), material barrel, separation kettle 1, separation 1 heater, separation kettle 2, separation 2 heater.

  

Rectification column system job description:

1) Rectification column size

Φ127 × 13.5 × 4000mm, inner diameter Φ100mm, diameter-to-height ratio 1:40, design pressure 30MPa, working pressure ≤26MPa, material 304 stainless steel tube, three-stage gradient temperature control, working temperature: room temperature -65 ℃, The water jacket is heated and insulated, and stainless steel packing can be installed in the tower according to the process requirements.

2) Application process

A: Extraction kettle → separation kettle I → separation kettle II;

B: Extraction kettle → Distillation tower → Separation kettle I → Separation kettle II

3) Main functions:

The CO2 entrained in the extract enters the rectification tower through the control valve through the control valve. By changing the pressure and temperature of the rectification tower to "stepless" adjustment, the supercritical CO2 dissolving ability can be "fine-tuned" to achieve the selectivity of target compounds Extraction, separation and purification. Typical product: Capsicum pigment extraction, red pigment with high color value is obtained at the bottom of the distillation column, and essential oil is obtained at the bottom of the separation kettle.

4) The rectification tower system includes: a rectification tower, a rectification tower heat exchanger, an automatic back pressure valve, and the rectification tower outlet pressure is automatically adjusted.
