Transcription of videotutorial for Herborizer Mini Closed Loop BHO Extractor :

Today we are going to show you how to use a mini closed circuit extractor for BHO like this Mini Closed Loop from Herborizer.
We’ve opened the box and got everything on the table. The 2 tanks, their safety caps with valves to open and close the gas flow, the pressure gauge, this is the extraction tube, the flanges (2 large and 2 small) with their respective rubber seals and the gas hose.
Today I’m here with Alchimia’s extraction specialist Jérôme, who will be helping me assemble and operate the Mini Closed Loop.

Hey Jèrôme, what's up?

- Hi! How’re you doing?

Very good. Let's start to assemble it and then see how it works. Come on, we start with the tank...

As you can see, we’ve assembled the closed extraction circuit very quickly. Now it’s set up to have the gas in this tank, for the gas to pass through here, in here we would have the weed, we would recover the BHO in this tank and through here we would retrieve the gas to get it back in this same container.

Is that right, Jérôme?

- We only need to reconnect this tube here to be able to recover the gas in this container.

And the first thing we’re going to do is to fill this tank with gas.

- We don’t need everything, we’ll just take the tank we want to fill with gas.
Because we’re going to do it outside, in the fresh air. For safety.

- Of course, always outdoors!

Let’s go.

We’ve come outside with the tank, it’s valve, the hose and the vacuum pump. This pump, the Rothenberger is a bit bigger than we need, but it’ll be fine. The first thing to do is to create the vacuum in the tank so we can fill it with gas.

Correct, Jérôme?

- Exactly, we’ll create a vacuum so the gas fills the tank more easily. Starting with fingers…

We connect the hose, and then we'll close it tightly with the spanners, right?

- That’s it.

For safety’s sake.

- Safety first. Because there’s gas, it must always be tightly closed.

That’s perfect, closed tight. We connect the vacuum pump, the valve is open, and we can start the pump...

- It’s open. Let’s go...

This process won’t take long.

- Because the pump is too powerful for what we’re doing, it goes very fast. We can already see that it is done in a few seconds, so first I’ll close the valve…

Close the valve and I’ll turn off the pump.

- So we’re sure the tank is under vacuum. Let’s disconnect the hose so we can start to fill with gas. Just insert the canister and begin…

We open the valve at the moment the gas starts to enter.

- So no air gets in. Keep it straight to stop any gas escaping. You can put 1 canister in, or 1 and a half, or 2 canisters. Now to remove it, there’s always a bit of gas left…

And we take the other canister, fit the adaptor.

- This is why we have to do it outdoors, because there are always small leaks. Let’s go again…

So we carry on filling the tank until the noise tells us it’s full, right?

- That’s right.

So we’ve loaded the gas, we’ve closed the valve and now the tank is full of the gas we’ll use for the extraction. The first thing we’ll do is to remove the mystery oil…

Right, Jérôme? What is mystery oil?

- That’s right. It’s a lubricant that they use filling the canisters, it doesn’t matter whether it says “No Impurities” or not, they all have it. It’s a lubricant they use to help the gas into the canisters…

So, to keep this oil out of our extraction, the first thing to do is use the closed circuit to remove the oil.

- Yes. You’ll be able to see there’s a significant residue left behind.

Let’s set it up to do the first extraction to remove the mystery oil.
We’ll create a vacuum in the whole system, so we connect the pump to this valve, pushing it on firmly. OK, perfect, and… tell me…

- So, we’re going to create a vacuum here in the system, then we need to check the valves. We leave this one closed, always, and open here and here…

And we can start the pump?

- Yes. It pulls the vacuum very quickly. There was a change in the sound of the pump’s motor which means we’ve got a vacuum. So now I’ll first close the valves… and you can turn the pump off. We have vacuum.

OK, let’s remove the hose. Very good. We’re going to do the first extraction, this time without any weed. We’ve got the gas here and we’re going to bring it over to here. What do we do Jérôme?

- We’re going to help with the temperatures to move the gas more easily. So, we’ll put this tank into a bucket with ice. It’s important to check all the valves are closed when we move it. There’s the ice, and to help the cold be more even we can add some water to make the cooling more effective.

Perfect.

- Now we’ll open this valve so that the gas passes through here, open this one, but you have to make sure this one is shut. So let’s go, open this, we can hear that the gas has moved a bit and to help it we’ll hold this tank like this a few minutes.

To help the gas go down, I shake it a bit to see if there’s still liquid in there. There’s still some liquid, I can hear clink clink clink… we’ll leave it a bit longer.
Now all the gas has gone through, it’s been about 10-15 minutes and now we can close the circuit.

- That’s right. Now, for safety, we start by closing here and here. Here it’s shut down for now. Now we’ll remove the hose to reconnect it here…

We’ll put the tank inside this bucket because now we need to cool this other one. Remove the big one carefully… and now we can put the ice and water in. The water makes the temperature more homogenous in the entire bucket.

- And we’ll put the hose in the exit.

We’re doing this to recuperate the gas… this process.

- Yes...

We should have the mystery oil here in this tank, so let’s see how much there is, but to see that  and to open the tank we first need to return the gas to it’s original tank.

- It’s closed tight…

Perfect. Very good. Now we’ve closed all the valves…

- Everything is shut, we’ll check it’s all closed. We open here, and there was a little noise which means the gas is starting to move through, so we open the other one. That’s it, the gas is now going to the other tank…

So now we wait.

- That’s right. To help the process we’ve filled this bucket with some hot water and we’ll put this tank in it so the gas goes into the other tank easier. Let’s check if there’s still gas in this tank… actually it’s all gone.

We’ve seen that there’s practically no gas left, we’ve moved the tank so now we can close the valves and see…

- We’ll close here.

We’ll close the other side too.

- The whole system is closed. The gas can’t go anywhere. Let’s disconnect the hose with the tools. As we open it… there’s always some gas, it’s normal.

But it’s not much.

- Very little, it makes a hiss. A drop.

It’s what was left between the two valves, in the hose. Let’s take the tank out of the hot water.

- And here, the same, there’s always some pressure and some gas inside. So when we open, there’s some noise, but don’t be alarmed, it’s not much. Keep opening it… there. Now, I’ll need more than my fingers for this…

With a screwdriver or other tool we can open the tank… and since this is the 1st extraction, without weed, we’ll see if there’s any mystery oil left from the gas.

- Ok, we’ll take a bit of paper…

Let me hold it for you, and we’ll see if there’s any residual oil… there’s a bit, so that’s the mystery oil. Now we can be sure that the gas we’ve got in the other tank, still with the ice, is completely clean, now we can use it for the extraction we’re going to carry out now.

- And if you smell it, it smells like motor lubricant. I don’t think we want to be smoking that…

No, no. Of course not. Let’s get on with it, we’re going to load the tube with weed. We’ve got some trim and small buds here, right?

- They’re small buds and some trim of Biker Kush from Karma Genetics...

Perfect, so we open the valve of the tube, remove this piece. Remember that when we assembled it, the loose rubber seal was above, and below there was a seal with a screen, so the weed can’t pass into the tank.

- Exactly. So we don’t get leaf matter in the tank with the oil.

Exactly.

- So, we can use, this would normally be for 45g, it’s a bit optimistic, we’re going to use 20-30g. We can pack it down firmly, there’s no problem with this system…

Also remember that the trim and buds are frozen, in this case it’s fresh frozen grass.

- Fresh frozen, to get what we call Live Resin, an oil that has more terpenes, so the flavour is more intense than with dried grass…

We’re going to do the extraction with weed and we’ll also work with the temperatures. We’ve got the circuit under vacuum and we’ll cool the part with the grass and the tank where the gas will go. A little more ice…

- It’s better if you can use dry ice, it cools much more than normal ice, but it’s harder to find…

Perfect, and now we put the tank with the gas in it into hot water, so that when we open the valves it goes through here.

- So, let’s open the valves, this one first…

The valve where the gas is…

- …and there. You can hear the sound of the gas as it goes towards the grass to put the oil in the tank.

Now 10-15 minutes have passed, and we’ve got all the gas here with the extraction, the BHO, which will be in this part. Now we can close the circuit and then we’ll retrieve the gas again and remove the extraction. To recuperate the gas, always remember that the gas will go from hot to cold, it moves away from the heat and goes towards the cold, so now to retrieve the gas we’ve got here into this tank, we’ll swap the hot and the cold buckets over.

While he removes the hose and fits it in the lower part to recover the gas, remember that this is a closed circuit that recovers the gas. We can use the same gas for multiple extractions.

- There is very little loss, so we can use it many times.

Perfect.

- There we are. We close it. Now, so the gas goes from here to here, we swap them over…

Swap the heat, perfect. The tank with the gas goes over to the hot water and the other one into the cold bucket.

- Let’s add a little more ice now and then open the valves so the gas starts to move. So I open here, and here. You can hear some noise from the gas. Let’s add some ice here…

Now we’ve recovered the gas, 15 minutes have passed, now let’s close valves, circuits, and remove the extraction.

- That’s it. We start closing here and here. Remove this, this, tools. Check its all closed, no messing about…

Correct.

- And to finish… Wow!! Look at all that! There’s always some stuck inside the tank, so we need to spend a bit of time with a silicon spatula or something similar to get all this tasty oil out.

We’ve removed the extraction and now all we have to do is purge it. To do that we’ll use the BHO Vacuum Purge Kit, which is the chamber and the pump, as well as a heating plate which we’ve set to around 70ºC more or less.

- At 70ºC, so it heats up the plastic a little, so it’s warm inside. It’s a lot easier to purge with heat. So let’s put the oil inside, right here…

Let’s open the chamber, put the oil inside and the purge will basically remove all the residual gas. It’ll be running for 2-3 days, purging and getting all the gas out.

- Yes. I’ll start the pump. There we are. We should take care at the beginning of the purge that it doesn’t inflate too much, in that case we’d have to turn it off and on again… this time it looks fine.

That’s it then. We’ll leave it to purge for a few days.

…72h of purging have passed. We think the extraction is purged enough now, right Jérôme?

- Yes. After 3 days we can see how the appearance has changed, we can open it now. We need to be careful it doesn’t all move, so we let the air in slowly (we can hear the air going in…) and that’s it. We can take the oil out.

Let’s see how it looks...

- This is how Live Resin turns out, you can see it’s got a crumbly texture...

Now it’s time to try it out, we’ve got the e-nail heated up to around 340ºC and let’s see how Jérôme takes his dab…

So, now we’ve seen how to use this mini closed circuit extractor from Herborizer, the Mini Closed Loop, big thanks to Jérôme for his help.

- With pleasure!
