Tuesday Tech Talk!

6 December 2016
Or maybe it is more like a Tuesday Tech Question: Does anyone of you have any idea what this is? What it is that we are developing?

Makes sense.

You said the nature gas is the further. You said direct heating is better. You said direct heating create more maillard reactions. And now you turning to the electric heating?

Well, Wavy, it is almost a poem you have written. Not sure what you are trying to say, but yes direct heat is better. More economical and more/better taste. There are two options of direct heating: gas and electric. Electric gives more control, gas is at some places cheaper. Hmmm ... its not like we are turning to electric, really. We have been producing electric units from the start onwards.

Dear Odin, you are my enlightenment teacher in whiskey producing, I've read out all of your articles, and no doubt I will follow all your viewpoint. Beacuse no one ever explain the principle so detailed like you, professional and easy to understand. So plz let me say thank you to you! Just maybe the direct fire heating has deeply marked in my mind, so I almost forgot electric also have a very high temperature on the surface and it can also create millard reaction. Sorry boss, thanks for replying. BTW, my plan is to have a istill in my studio. I belive that science is power. Best Regards wavy

Here’s a false assumption I often hear: “I have a potstill and bridge to the cooler and the tube through the cooler are open to the air, so my system does not build up pressure!” ah, yes, I used to think that way either... and I even read the number from the boiler, it can't even reach to 0.1MPa. But, it's wrong.

why its wrong, when you put your finger near by the outlet of your condenser, you can sense that the gas are rushing out your pipe without enough cooling water to condense your vapor to liquid. so its easily to realize that the vapor is rushing though your column and condenser.

Very interesting read, as always! Will all robotised units share the same column cooler design (that looks like a Dephleg) as the 2000l pot? Another question: what is the difference between the cooling head on the old iStill (wound ss tubing, I think) and the new cooler. I know the obvious difference, in design, but just interested how it impacts still performance. Apologies if this is a dumb question or you've blogged on it before.

Yes, they will, Craig. So far the 2000 uses the new shotgun cooler where the 500 uses the older style with wound ss tubing. The wider diameter needs the upgraded column design. In the future I foresee the iStill 500 also will use this new tech for reasons of standardization, even though it works fine as it is right now.

Thanks for the reply Odin. I was doing some reading on HD regarding cooling etc. and just wondered if there was any technical benefit the shotgun brought over the wound SS. I can see how on the larger diameter units. Never mind. Keep up the great tech posts anyway.

The advantage is bigger cooling capacity, more open space and a more even spread of the open space. All important on the bigger columns, not a nececity on the 5 and 3 inchers.

Looks like a copper pad but it is the wrong colour., some sort of filter?
