What are you gonna start using
Thatās a much larger pump than the mvp6, ya? And at some point it hits 1.5. Whatās your average, youād say. Because at my curve, Iām probably pushing 4lbs a min.
And not to sound rude or anything. But, I not that concerned with what the pump can do at āmaxā. More or less, whatās the average, is what I like to know.
A bit over 1#
The mvp150 is the same, 6cfm pump as the mvp60 itās just able to handle higher pressures. Same size motor, different internals (as far as I know)
Not going to lie, Iāve ran a few mvp 150ās and even at anything close to 100f, with a propane blend, I didnāt see 1.5 a min. Granted they all were incorrectly heated, with very weak kiss heaters. Only thing Iāve seen remotely close, is the blackmire. I know the korken is much beefier and is capable of more. But, without scorching your product. I canāt see a pump keeping up with me at nearly the same temperature. Unless it costs more than my system itself. I recover at literally half the temperature of what this post is claiming. Maybe going hotter isnāt the key, just saying.
Aye, Weāre all skinnin cats here.
I chose the MVP because for one I got a good deal, two I am local to the company and they have fast turn around times incase it does go down, and my only other options at the time were haskel or the punisher. Iām really happy with it. I dont have the ability to go passive at this time.
How do you keep the dust from the silica/carbon from contaminating your solvent like mol sieve beads do?
Iām using an MVP-150 and Iām around 1-1.5#/min depending on ambient temps.
Not even close to worth the 8 - 10k youāll spend versus passive.
At scale, you cannot beat a pump. If youāre trying to break 150 - 200 lbs a day passive is gonna be a huge headache.
At smaller scale, why introduce the burden of extremely high sound (requiring hearing protection) and added electrical components?
Passive all the way unless youāre pushing for industrial scale, then go for a pump.
Also, whoever is in here talking about latent heat of vaporization, is right. Your limiting factor in most cases the heat provided to the evaporation vessel (collection vessel) is what is doing the bulk of work in regards to how fast recovery is occurring.
Also, Iām with @Dred_pirate on temperatures of evaporation.
Sureāthe bulk fluid will never reach 150C before completely boiling off, but if you consider the contents of the collection vessel as homogenous, then the boundary layer, in which most of the vapor is formed will be superheated to near the temperature of the heating fluid.
In this minute boundary layer terpenes are still becoming gaseous and escaping the system. High power, low temperature.
At least Iām not talking to a wall. You understand what Iām saying. Thank you.
And if I had the right chiller, I could easily run that much in a day. But, I donāt do large, large scale.
Next time I go to see the Oklahomies, Iāll have to see it run that fast.
Iād honestly be worried about the oil making contact with the wall still.
I have always been worried
But it shatters ! I agree with @Dred_pirate on possible terp losses
But I can get away with that for now
In the land of. The blind one eye is king
An other negetive factor in my sop for now is I collect after 5 runs
Meaning that the terps of the first run
Have been treu 5 evaporation stages
And for sure on every run I loose some
Not disagreeing with high(er) collection pot temps equaling loss of flavor profile but curious if anyone thinks that due to positive pressure of collection vessel would adjust terpene bp?
My collection tends to sit around 50 throughout run and I tend to pour(spout) at around 20psi(into mason jar)
Havenāt looked at bp chart latley but arnt most recorded bp for terp/flavor profile at atmospheric pressure?
Not trying to derail this thread but been wondering about this a while.
As far as reciprocating gcās anyone know why all cannabis equipment retailers have necked opening down/ added a lot of 90ās?
Illuminated extractors on ig has the configuration I imagine to be most effective but I believe the corken they use is also bigger than t291.
Damn what are you using for solvent pouring at 20 psi? I pour at like 4 psi, into jars as well. 0 psi for shatter
Lots of oil soaked shirts id guess
Haha! Right? My wrists get splattered at 5 psi
i mean technically boiling the terps off makes snappier shatter
WHo WaNts tHaT?!
People who arenāt in this to make fire, thatās who
I was a devout member of the passive church until I needed to run 200# a day and then I needed a new player on my team a MVP and @TheGratefulPhil is right to scale we must plug inā¦like Dylan did and damn the haters
Dred letās say for example that a 2" line set can flow 10 lbs/min butane vapor when conditions and pressures are just right to achieve that particular flow rate.
Well then why canāt you just put 2" lines on any old passive system and magically recover at 10lbs/min?
If I started selling 2" wide lines with the tagline āRecover passively at 10lbs/min with these lines!!ā would you think itās true?
Itās the same with these pumps. Just because a certain rate is advertised doesnāt mean itās easily achievable right out of the box.
A pumps flow rate, just like a plain old hoseās flow rate, usually involves some carefully planned āgivensā like inlet and outlet temp/pressures which cannot be reproduced consistently across all extraction systems. If you supplied unending vapor at the right inlet/outlet pressure it would likely hit the advertised rate. The supply of vapor is generally our biggest limiting factor in extraction.
Of course resellers try to ham it up as much as possible and I certainly understand your frustration that youāve bought into their shtick. They take ideal conditions and then give you the best rate for the top of the bell curve under those conditions.
But thatās all just advertising. Taking their claims at face value is like believing the off-the-shelf āpower boosterā additives for your gas tank will really give you the HP numbers listed on the bottle.
Huh? What does that first sentence even mean?
I mostly research and write this shit out for myself, not anyone else. I donāt give a care if you address me or not. Honestly most of what you say is conjecture posted up with no supporting evidence.
Do you only read the forum on your small phone screen or something? I know I write more than most and I also know 90% just skim right past it but if you take out the wide side margins this forum has what I actually write is no more than a few decent paragraphs.
I feel like I need to provide evidence for my posts. Itās not acceptable to me to just write something with the caps lock on and present it as established fact.
Again, I donāt understand what youāre talking about here.
They definitely load/unload massive tanks and rail cars with compressors. What do you mean by āmassiveā industries? Iām really confused by this, please explain.
In certain areas Iāll admit I do need schooling but so do you. I recommend you start with reading comprehension. I know these longer posts really bother you but take some time and read carefully before firing back.
Did you read the definition of latent heat of vaporization? It means that in fact, no, your extract will not be āheated to that degreeā if itās in a highly diluted solution.
Do you understand the pressure/temperature curve and how it relates to the temp of your boiling solution?
When the solution is heavily diluted its temp is correlated with its pressure, not the temp of the heat exchanger.
If the heat exchanger is at 150F and pressure is 23psi (butane) the solution temp is only 80F. If the heat exchanger is at 85F and the pressure is still 23psi, itās still at 80F but itās boiling off at a slower rate.
Did you read the part where I said higher heat is only acceptable when the collection pot is highly diluted? Thatās very important.
If you have a highly diluted solution the probability that a heat sensitive molecule will ever encounter heat that will damage it is extremely low.
Even if a terpene hits the heat exchanger at 150F that doesnāt mean it will heat up to 150F instantaneously. It will likely take on a little bit of heat and quickly ricochet back into the solution and be cooled back to the solutionās boiling point.
For fuckās sake, Iām not recommending 150-160F to everyone. Thatās just what Roguelab said heās using (70C) and I said it should be ok IMO.
Iām not too concerned with ācuck operatorsā (is that who youāre consulting?) and what they might forget to do. Iām on top of my shit. I didnāt recommend 150-160F as something for everyone to try. However, in a large system with a highly diluted solution it should be ok for a short time. Especially if you are using pure propane and your solution temp is way lower than butane.
Iām just saying you can up the delta T when conditions are advantageous for a boost in vapor generation without damaging the oil.
