Difference Between Small and Industrial CO2 Extraction Machine

Small CO2 extraction machine

In the design of supercritical CO2 fluid systems, a small CO2 extraction machine usually refers to a small extraction capacity(For example tabletop co2 extractor), which is used for small experiments in the laboratory, research, and confirmation of the extraction process, and finally, scale up the mature and correct CO2 extraction process to an industrial supercritical CO2 extraction machine for scale. production.

Industrial CO2 extraction machine

Industrial CO2 extraction machines are customized or general-purpose CO2 extraction machines based on the results of small-scale experimental studies. There are many customized contents: the third separation kettle; ultra-high pressure, up to 105MPa; rectification column; cold trap in the separation kettle, etc.

Difference Between Small and Industrial supercritical CO2 Extraction Machine

Small

Capacity: Extraction vessels from 100ml to 5000ml.

Pressure: The maximum extraction pressure is generally 50MPa (7250psi), up to 105MPa. Note: 100ml and 200ml machines are special examples, 35MPa (5000psi)

Separation Vessel (Collector): Two to three separation kettles are normally equipped to collect light and heavy components.

Distillation column: SFF is a very important process in supercritical fluid extraction, and it is often the configuration specified by some laboratories with higher requirements.

The gas is recycled and reused: In some household extraction equipment we have seen, it will discharge the gas directly through the separator. In the laboratory, the economical use of the gas must be considered, so there must be a professional pipeline to circulate the gas through the filter. To CO2 gas storage for recovery extraction.

Industrial

Extraction kettle: The extraction capacity of a single kettle ranges from 10L to 3000L, or even higher. The extraction system consists of two to three extraction containers, and a maximum of 6 containers are divided into two groups to work alternately, which is efficient and economical; large-scale extraction is equipped with a pneumatic opening mechanism.

Pressure: The maximum working extraction pressure of the 10L-30L extraction vessel is generally 40MPa (5800psi), and the ultra-high pressure represents the ultra-high cost. Of course, in special cases, it is still necessary to customize a high-pressure extraction container. For example, the extraction of astaxanthin from Haematococcus Pluvialis requires very high pressure.

Separation vessel (collector): normally equipped with two separation kettles for collecting light components and heavy components, of course, there are three customized separators.

Distillation tower: Configure according to needs, such as capsanthin, animal fat removal, separation of wax and chlorophyll during cannabis extraction, etc.

CO2 recovery system: It is recommended to use a gas recovery system in the extraction system with a single kettle of more than 30L, which will maximize the use of the gas in the gas container, and at the same time, the gas in the extraction container can be recovered, saving gas and reducing costs.

Pressure regulation: For pressure regulation, the extraction system with a single kettle of 100L is usually equipped with an automatically controlled pneumatic pressure regulating valve.

CNC control: The system is equipped with a CNC control operating system to control the adjustment of temperature and pressure during the extraction process.
