Hey guys, it’s Todd from Pull Espresso Machines. The last video that we made was about pulling a shot actually how to pull a shot now I talk to you a little bit about why the shots differ so much on a Hand Pull Machine, like ours as opposed to electronic machines and why it’s better. Actually, the piston mechanism on this or the actual head itself. This is 22 pounds of solid brass with the stainless steel sleeve on the inside so you’ve got to imagine there’s so much more thermal mass they call it or its larger bodies of water obviously hold maintain temperatures larger bodies of thermal mass meeting brasses and brass is a fantastic conductor of heat and maintains heat very well much better actually than stainless which is contrary to what most people think so what happens is you’ve got 22 pounds as opposed to let’s say on a pound or maybe three pounds on it which is pretty large and the commercial electronic style of heads and what that does it holds that this larger head holds the heat in what does it holds the heat in and maintains the temperature so you’re not going to get that that temperature swing like you would on electronic machines. So that’s one factor. The second factor is your you have a pre-infusion. That is superior electronic machines when you press the button it goes 0 240 PS i all at once there is some machines out there tried really hard electronic machines are trying really hard either getting better every day to pre-wet our pre infused the coffee and the that terminology pre-infusion is used a lot in espresso machine manufacturing an advertising the difference, is they might get a second or a moment where tries to pulse there’s also pressure profile is all this technology that cut that has come out to try and mimic what these machines actually do better than anything the way that ours work it doesn’t go 2014 t or even a couple different graduated marks what it does is it goes from 0 to 20 psi very slowly and gradually and that actually is happening when I pull the piston down when I pull the handle down pulling a piston up and I’m basically compressing a spring allowing the water to flood in the chain amber once the water floods in the chamber it’s flooding at 20 psi gently up to 20 psi then when I release the handle up in the up position I’m uncompressing the spring, I’m allowing the spring to to push the coffee through or push the piston down what happens then is it gently extracts and goes from 0 to 20 then from 2240 PSI electronic machines just can’t do that they are they struggle with trying to bring infusing pretty wet also our machine has five ports or five entries in in which the water floods the chamber as opposed to electronic machine it only uses one single tiny pinhole and when that hits us a screen or diffuser block what they’re trying to do is we’re trying to get it to disperse the water and make the water shower or evenly extracted the coffee ours does it very very easily me the only analogy that I’ve been able to come up with that that kind of makes sense the most people is a syringe if you and I hate to use it because it’s kind of doesn’t sound very good, but it’s the best way to explain it a syringe you pull it up to draw an exact volume of water these machines actually drawn exact amount of water just like a syringe the chambers filled once the chamber is full the coffee holds the car holds the actual water from flowing through that coffee bed but in that in the interim what it’s doing is it’s pretty wedding the coffee so then when the spring continues to push after I pull the hell down and let go of the handle we get this gentle extraction and gentle from zero 240 psi so not only do we have a superior heat retention we also have a superior much more superior temperature throughout the better the coffee throughout the whole brewing process and that’s that’s pretty much the main reason. Another thing that we do that no one else does, is we do direct group the boiler so if you look at some of our our information look at some of the photos of the inside of our machines you’ll see that they hit the actual head is bolted directly to the boiler we actually silver braised silver solder the head to a flange and that flanges is connected to the water so we have a heat transfer we’re not using copper lines or stainless steel lines reason copper boiler also which is a better heat transfer the stainless like i said before and what happens is it transfers the heat more efficiently thanks for checking us out I just wanted to let you let you know about that feature and we will talk to you guys later.
