VTA SOP, you guys asked for it so here it is

It all depends on which way your wiper blades wipe, some wipe up some wipe down. If your wiper blades wipe down they push the crude down, and along with the pump pushing crude out the top and gravity your residence time would be lower. If they wipe up then the crude would be pushed up against the falling crude coming from the pump up top. This might increase residence time a little, I think gravity and your pump would win though. 2 forces vs 1.

Heres something to think about

At 130 hz on the feed pump, your flow rate would be the same whether your basket is at 50 or 100% (even with gravity and the wiper blades pushing up against the pump)

The wiper basket spin makes your crude travel a longer distance resulting in more surface area for contact which allows more heat transfer making your evaporator more efficient. The evaporator still has to distill all the cannabinoids before the crude reaches the bottom, more spin means a longer distance traveled in the same amount of time (the flow rate never changes, only the distance the wax travels because of the baskets spin changes)

If the basket slows the crudes flow enough your evaporator will become flooded and the crude will fall over to the condenser side,

Thanks! I have a much more clear understanding now.

how do we convert hz to mL per min on the perlstaltic?

For the VTA pump or just any pump in general?

In general I just don’t know wha tryout talking about when everyone says hrZ is there a conversion to ml per ml?

Hz=Hertz

It’s a measurement for Cycles per second.

Its relationship is dependent on what you are measuring. In this case, it should rely on the rotor size(one rotation per second = 1 hz) for direct drive pumps but can not confirm the relationship for the VTA

What is an ideal fluid for a rotovap at 150C? I have PEG 400 right now and that steaming/smoking at 140C+
Normally for us, we bring it to 110-115C for decarb and it doesn’t smoke at all at that temp.

Am i just worrying to much about steam/smoke? should i let it go and disregard the steam /smoke?

Valve that all over. Protect it from backstreaming.

Keep it under 160c, im told this works

Is the flow rate measured in Hz specific to the VKS? I’m running a 2" pope and i don’t understand how i can quantify that until after the run is finished, measuring ml/h.

Also just to be sure 3.5x10-1 mbar is 350 mbar, corrrect? I cant see it being at 34 mbar

Do you have the stock feed pump?

I dont believe it came with a feed pump. The feed flask stands above the evaporator allowing gravity, heat, and vacuum pull it down.

@Kingofthekush420 I run a VKS and the diffusion pump on the second pass goes to 10-3 while the machine is not running but as soon as you start feeding product, it goes to 10-2. Is there a way it will stay at 10-3 while the product is running?

Slower feed can get you lower vacuum, you could also have a leak

Whats your terp strip parameters?

Same as your

Any chance you can message me about coming out to consult?

On the parameters you mention Residue @ 115c and Evaporator @ 158c. Are you referring to the residue as the condenser within the evaporator body or is a separate component? I tried to look this system up on their website and thought I would just ask.

No, the residue/raffinate side has it’s own heater on the VTA. There are like 5 heaters/chillers on that thing
