Supercritical CO2 extraction of cinnamon, coffee, and vanilla with dry ice----make money online

hey everyone I've done some work with

supercritical co2 extractions before but

this time I wanted to build a device

that didn't require having a tank of

liquid co2 which is something not a lot

of people have and also I wanted to try

some different Oz different ingredients

so I tried cinnamon sticks ground-up

ground coffee and chopped up vanilla

beans as you can see the yield is not

exactly what you'd call impressive but

this actually isn't too far off from you

know a commercial yield using like the

best supercritical co2 extraction

techniques for vanilla beans you would

probably only get about 5% extract so I

actually found a paper talking about

extracting vanillin or oleoresin from

vanilla beans and even they were only

able to get about 7% at the absolute

maximum and with lower temperature and

pressures which is what I'm working with

here the number will be closer to 1 or

2%

I built the extractor by machining a

piece of aluminum into two end plates

and I carved in a gland for an o-ring

in either plate and then taps the center

hole with an eighth inch pipe thread I

then used a few 3/8 inch diameter bolts

to hold the two end plates together and

I used a piece of acrylic with a half

inch hole drilled in the middle as the

chamber itself this is really much

better done with metal I mean stainless

steel would probably be the best

material to choose but I really wanted a

clear materials that I can see what was

going on in the extraction chamber one

problem with using acrylic is that the

supercritical co2 actually penetrates

into the plastic itself quite easily so

you really can't leave this set up for a

long time like a day or two to get more

oil extracted from your ingredient

because he'd actually end up extracting

a lot of the plastic itself I searched

for quite a long time looking for a

chunk of glass that would be big enough

to hold this amount of pressure and the

closest thing I could find was

steam boiler gauges to show you the

water level inside a boiler and what

they consider is high pressure is about

600 psi which is not really enough for

this application this thing will be

working at about 1,500 psi minimum and

ideally it would be more like three or

four thousand psi since I wanted this to

work with dry ice as the source of co2 I

set up another chamber on top of the

extractor and built this out of schedule

80 steel pipe and these are all stock

parts the valves all the pipe fittings

and the and the large steel pipe are all

stock from McMaster I added a small

copper disc mesh screen to the bottom of

the extraction vessel and then added

some fiberglass on top of that just to

serve as a filter to keep the particles

of my ingredient from getting down into

the valve I cut up about one and a half

vanilla beans into small like two

millimeter long segments and packed them

into my extraction chamber I then hacked

up a piece of dry ice and packed the

large steel pipe full of it and then

screw the top on and applied heat to

melt all the dry ice into liquid inside

the chamber I tried a few different flow

rates but knowing that my acrylic

extraction chamber really shouldn't be

exposed to co2 for a long time I didn't

want to use time periods of like an hour

or so so I was shooting for mostly about

5 to 15 minutes extraction and what I

would do is set the bottom valve just

high enough so that there was a small

flow rate moving through the vessel and

the top valve was completely open during

this whole process just so that the

supercritical co2 could flow from the

top chamber down through the material

and then out the bottom and to catch the

yield to the product I just put a test

tube underneath the pipe fitting at the

very bottom and what would happen is co2

would come out and then freeze into dry

ice and then I would occasionally heat

the test tube just to keep the dry ice

from building up with really low flow

rates the amount of dry ice production

wasn't much of a problem and just

ambient temperature was enough to melt

it I added a flexible heater to the

valve since the decompressing co2 draws

so much heat that valve it actually

frees up pretty often so a small

electric heater to prevents that from

happening after I used up all of my co2

I took the test tube over to the

centrifuge and ran it for just a minute

or two just to move the contents down to

the tip so there's a few more things to

work on I ideally like I say the chamber

should be stainless steel or something

else one so that the pressure and

temperature can be higher and also so

the he knows it doesn't dissolve into

the supercritical co2 you could actually

have something that would be

long-lasting but the basic idea is here

where you'd pack a reservoir full of dry

ice and the driest you can get anywhere

you know even grocery stores have it now

and then seal it all up and do your

extraction that way without any unusual

equipment I think one problem will be

the overall yield so really you're only

going to get a few percent of mass of

what you start with so your extract is

extremely concentrated and I'm not

really sure how you would use it so if

you're going to use it in cooking or you

know maybe perfume manufacturer or

something like that it would have to be

very small quantities involved or the

chamber would have to be much larger

than I've designed it maybe using

stainless steel the extraction chamber

could be you know five or ten times as

big okay see you next time backTop Search Keyword : online earning, , make money online, earn money online, online earning, online earning sites, make money online free, online money income, earn money online free, money online, best way to earn money online, online income site, money earning websites, best online earning sites, easiest way to earn money online, earn money payment bkash, online money income site
