There’s definitely an azeotrope formed between p-tos used that can form from the oh groups on the cannabinoids

I doubt it…

Perhaps you could restate that without using the word azeotrope?

substitute that definition in for the word azeotrope in the sentence above.

Does it make sense?

Would the “azeotrope” you’re proposing not result in p-tos in the receiving flask?

Is that what you mean?!?!”

azetroping

Stop using that word. It doesn’t mean what you think it means.

“Thermocouple” is a shortened name for thermocouple pair. They are just two wires twisted together. So long as the two wires are not the same metal they form a thermocouple pair. When the metal in the wires is known a circuit can measure it and amplify it because it produces a voltage in relationship to the heat at the metal junction.

Wiring two or more thermocouple pairs in parallel will produce two or more voltages, one at each thermocouple junction. In parallel the voltages will average each other. Low on one and high on another results in a voltage midway between all thermocouple pairs wired together this way and the control will see then the average of all as one voltage input.

Adding resistors costs likely fifty cents lolz but is necessary and is outside the scope of this blog to explain why but it is because each thermocouple pair is a slightly different length and the calibration circuit cannot deal with this with accuracy unless matched with swamping resistors this way. You can look it up…

The controller only sees one input like this but it is averaged. If you had ten thermocouple pairs wired in parallel this way it would average all ten together as an example of how far you could go with the design idea. I am just wiring a new idea together using this well known technique for high precision thermal control in my own SOP.

I’m now gonna have to learn of swamping resistors so the PID controlling the heat tape on our new wiper can use average temps.

@NitroCat … don’t neglect the links under the top post.

@Kingofthekush420 are you open to consultation on helping us dial in our Hive30 wiped film?

[Kingofthekush420]

Yes ill dm you

What’s a good decarb temp and time in a 20L jacketed reactor if I have 5-15L of crude oil?

[ECMachmer]

It is best to make your own procedure for the equipment and elevation you are in.

Starting temp 90 C. Increase vacuum till you see ethanol coming over. Balance here is fast but not so fast that you have ethanol getting into the vacuum pump.

As the ethanol evaporation dies down you can increase vac or temperature. Whichever lever is easier to pull is what I’d adjust second, in most cases that is vacuum. For example, increase to 100 C and then adjust vacuum up or down to prevent bumping. Bumping is when the stuff in the reactor escapes to the cold trap and/or vacuum.

You’ll reach a point where there is a lot of bubbling but no condensation. That is the decarboxylation and is normal. THCa converting to THC.

Repeat this until you are at 120-130 C and full vacuum. I prefer to go as high as 145 C but this depends on the material and/or farm practices. For example, biomass with high sulfur I’d stop at 120 C and heat it as little as possible for as short a time as possible. Pay attention to your chromatography if you have internal testing or CoAs if not.

decarbing i n a reactor at 135c full vac , how long is should it stay in the reactor before going into VTA to fractionate oil

[ECMachmer]

If there is no condensation in your cold trap or it is just refluxing you can move to the next temperature range or the next process.

Do you have any instructions on the vacuum controller for the HiVE30? I can’t seem to set the torr to where I need it.

[Kingofthekush420]

I do not, that unit im pretty sure is a digivac unit if i remember correctly

Thank you for this information.
