Hey Niel! Good question...As the two still vary in diameter and size I don't really have got a comparison to truly compare them. But can definitely look into it!
Hallo, according to my practical experience with alcohol distillery plants in Uganda, The bubble cap tray is more efficient than the sieve tray, they hold onto the liquid thus saving on weeping and steam loading...thus saving on losses..
@@limaroleonard8752 this is awesome! Thanks for the reply I appreciate it. I love the fact that with your on the ground experience it’s an easy answer. Keep it up! 👍🏻
I've noticed that continuous stills tend to use exclusively perforated plates. Perhaps continuous stills that use bubble plates, I just haven't seen them. Do you know why this is? My thought is maybe they flood? Maybe the efficiency isn't as high and worth the extra cost? Or maybe it serves a completely different purpose in a continuous still?
Hey Kristian! Man you got some good question there… Cost definitely plays a role, bubble trays (BT) are more expensive. Although BT reduced weeping they have much more disadvantages. BT have high entrainment, high fouling tendency and causes a higher pressure drop at the same flow rate as a perforated plate. Thanks for the questions, I love it!!
@@distillergreyling9135 Thank you for your reply! I'm in the process of planning out a continuous still that I'm building ATM exclusively for stripping runs. I was inspired by a whiskey distiller in Tasmania Australia who built one and it's simplicity was really attractive. It used an extremely long liebig condenser that was maybe 10 meters and snaked it's way back and forward down the wall. It used the wash as the coolant, which emptied into the top of the column. By the time the coolant/wash reached the top of the column, it was very close to 60°c, and so all the alcohol vaporized by the time it reached the bottom of the column. The boiler was only 10liters or so, and so, it used very little energy to boil, and no water at all to cool. Many commercial continuous stills are very complex IMO in order to keep them compact, but if space is not a factor, which it isn't for me, I love the simplicity of this design this Tasmanian distillery built.

Hey Kristian! Always glad to help! Your plan of simplicity sounds awesome and the continuous still in Tasmania sounds amazing. I just love how with a simple idea you are able to create something out of the norm and it sounds like its going to look stunning. All the best to you, your idea sounds solid! Sweet! 👍🏻
Thanks Hunter! I get you now, honestly I’m not sure. If the smoke is a bit moist I presume there can be condensate. But most wood fire is dry and chances are the smoke will just travel through the bubble capes. The will be a grater restriction for the smoke and it will want to escape to the most easily route. Very interesting question and thank you for making me think a bit! Cheers!! 👍🏻
Hey iStill, thanks for the comment. At the 3 min mark I do talk about the bigger perforated plate and that I actually use it in my gin basket. You definitely need to use a plate with smaller holes and a downcomer to make it really work as a rectifying/stripping tool. Keep it awesome. Cheers
Where it's available,we want to buy the perforated plate column. Can you tell me details and availability. How can I approach it to buy these product... Can u give the contact number.
Hey Narasinga! Where are you lacated at? In South Africa I know Distillique (distillique.co.za/products/2-inch-4-plate-glass-column?_pos=13&_sid=195f9f736&_ss=r) & Yeah Brew (yeahbrew.co.za/product/2-inch-4-plate-glass-column/) has got 2 inch plate columns. In USA you can have a look at Mile Hi Distilling (milehidistilling.com/product/perforated-copper-plate-down-comers-6-inch-diameter-set-of-six/).
Hi, how does flow rate compare between the 2 different plates on your still?

Think they'll make some water with wood smoke going through them?
Hey Hunter! Sorry for asking, do you want to smoke infused? I’m a bit lost with the question.
@@distillergreyling9135I was wondering the effect the caps would have say in a bbq smoker grill if they would create water from condensation
Thanks Hunter!

What about the perfirated plate you have with no downcomer? How does that work?
Hey Scott! I use the larger 4” perforated plate in a 4” glass sight-glass to act as a bottom for gin runs. The gin basket will be placed on the plate.
Holes seem to be too big and there's no down-commer on the perf plate, making it smear and not work correctly.

@@distillergreyling9135 Haha, sorry, couldn't hear you, Greyling! :)
@@OdiniStill try this one, better audio.

the bubble plates are non linrar.uthey do not create a linear temperature gradient along the reflux column. They consume more energy.
