The principle of super critical carbon dioxide extraction and separation process is to use super critical carbon dioxide to have a special dissolution effect on some special natural products, and to use the relationship between the dissolution capacity of super critical carbon dioxide and its density, that is, the influence of pressure and temperature on the dissolution capacity of super critical carbon dioxide.The operation of supercritical CO2 extraction machine is very professional. Let's take a look at how to operate supercritical CO2 extraction machine?

 

The following knowledge points are listed below:

  • Boot operation of supercritical CO2 extraction machine

  • Loading operation of supercritical CO2 extraction machine

  • Extraction operation of supercritical CO2 extraction machine

  • Stop extraction operation of supercritical CO2 extraction machine

  • Flush operation of supercritical CO2 extraction machine

  • Outage operation of supercritical CO2 extraction machine

 

1. Boot operation of supercritical CO2 extraction machine

(1) Open the total power supply of supercritical CO2 extraction machine on the wall (the bottom row number of the second from right). Open the separation extraction, separation1, 2 buttons, set extraction temperature (normal range 35 ~ 60 ℃, about 45 ℃) and 1 temperature separation (normal range 35 ~ 65 ℃, about 50 ~ 60 ℃), the temperature of the CO2 separation machine of 2 (normal about 35 ℃).


(2) Look at the three tanks water level from 1 to 2 cm, and check whether the pump of supercritical CO2 extraction machine is running (the pump surface have the fluctuation is commonly rotation or view the vane pump).


(3) Open the panel cooling power, start the cooling box (clockwise twist, 90, and vertical).


(4) When temperature of CO2 extraction machines reaches set temperature and cold machine stopping time when ready to VAT charging), open the valve 1 and 2 (counterclockwise spin 3 laps, each lap 360. ), open the ball valve (on the back of the host, reverse twist to level), close the valve 4, 5, 3, slowly open the valve exhaust (listen to the exhaust note), make the extraction pressure of 0, open the plug.

 

2. Loading operation of supercritical CO2 extraction machine

(1) Loading material to supercritical CO2 extraction machine: bottom-up followed by material (rate of not less than 5%, the amount of at least half of cylinder height, from the highest mouth 2 cm) a cotton wool (round, diameter ratio, screen 1 cm long) a white circle - filter - > mesh a lid (note anyway, fine mouth down, cover tightly with special tools, can use the hanging basket to live).


(2) Charging cylinder of supercritical CO2 extraction machine : bottom-up followed by a black thin cylinder type ring 0 a ventilation ring a plug (internal black thick type ring 0, wetting with water).

 

3.  Extraction operation of supercritical CO2 extraction machine

1) Close the valve 3, open the valve 4 slowly (counterclockwise twist slightly, modestly, make the extraction pressure and tank pressure is equal to the 1.)


2) Open the valve 3 slowly and exhaust 5 ~ 10 seconds, then closed.


3) Open the valve 4 and 5 (counterclockwise spin 3 laps, each lap 360" ), close the valve 6 ( first clockwise rotation 2, open the CO2 pump power, the green light (12 ~ 18 pump 1 frequency modulation, frequency range, generally 16 ~ 18, when set to 18), according to the running of supercritical CO2 extraction machine, the extraction pressure, such as pressure to set 1 (highest do not exceed 35 mpa, 20 ~ 30 mpa normally, at this time is about 25 mpa), adjustable valve 6 balance, close valve 8, rose separation 1 pressure (highest do not exceed 11 mpa, normal 8 ~ 10 mpa, when set to 10 mpa), such as separation of 1 reach the set pressure, pressure adjustment valve 8 make it balance. (note: separate 2 pressure can never be shut, and tank pressure equal) began to see the time cycle (usually a loop) every half hour.

 

4.  Stop extraction operation of supercritical CO2 extraction machine

Stop pump power (pump 1 FM), according to a red light of the supercritical CO2 extraction machine, slowly open valve 8 and 6 (in order) to separation and extraction 1 equals the pressure and the storage tank. Close valve 4 and 5, 3 slowly open the valve, exhaust, the extraction pressure 1 to 0, open the plug, cylinder is put forward.


Note: if you continue to do, starting from the loading operation of supercritical CO2 extraction machine.

 

5. Flush operation of supercritical CO2 extraction machine

Note: when cleaning the supercritical CO2 extraction machine, separate 1 don't need a booster.


(1) Flush operation of supercritical CO2 extraction machine is similar loading operation, but there's a difference. Don't put the charging bucket, pour into alcohol through the loading port is about 200 g, don't put a thin type ring 0, ring into the ventilation, cover the plug. When cleaning set extraction temperature for 48 ~ 50 ℃, extraction pressure for 20 ~ 25 mpa, similar to the following two steps extraction operation of supercritical CO2 extraction machine.


(2) Close the valve 3, open the valve 4 slowly (counterclockwise twist slightly, modestly), the extraction pressure 1 equal to tank pressure.


(3) Slowly open valve 3 and exhaust 5 ~ 10 seconds, then closed.


(4) Fully open valve, 4 and valve 5 (3600),close the valve 6 (clockwise rotating 2) first, open the supercritical CO2 extraction machine pump power, the green light (12 ~ 18 pump 1 frequency modulation, frequency range, generally 16 ~ 18, when set to 18), according to the running of supercritical CO2 extraction machine , see extraction pressure, such as pressure to set 1 (highest do not exceed 35 mpa, 20 ~ 30 mpa normally, at this time is about 25 mpa), adjustable valve 6 balance, and then began to clean.


(5) The adding methods of alcohol to supercritical CO2 extraction machine : first add asperse essence to carry agent tank (half of tanks), open pump 2, then open the exhaust valve pump 2 to asperse essence continue down, closed, several minutes, after adding alcohol, close pump 2.


6. Outage operation of supercritical CO2 extraction machine

Close the extraction pump and separation 1, separation 2 button, stop cooling box (and 90% counterclockwise twist to ground level), closed refrigeration button panel, close the panel power supply, the total power of supercritical CO2 extraction machine shut down , finally close the valve 1, 2, and ball valves.
