  1. Benefits of Tube in Jacket Condensers?

    Was an interesting read. But this also brings in to question the negatives of using copper in the cooling section. Years gone back it was understandable as to why copper was used. So with SS shell & tube condensers .....Taking it a step further with the time of cooling being considered, this means that cooling water entry ought then always be in "counter flow" in both RC and PC. Everyone generally does "counter flow" in PC but do "with flow" in the RC because of rising air bubbles in the cooling water. It also potentially means wrt extending cooling time within PC of slowing down flow and extending PC length.
  2. Still agitator

    A slightly different angle on this regarding agitator shaft sealing; ..... I see people using PTFE bushes, followed with carbon packing and then .......and then I see another just using a wiper / scraper seal (as for front of a pneumatic cylinder). Comments on just using a wiper / scraper seal because internal pressure within the still is so low and furthermore this is such an easy way to seal a shaft.
  3. Spray balls & water pressure

    Another angle, .. try not to exceed 2.5 bar.g at the sprayball otherwise you will start to atomise. Based on this you can work backwards wrt the pump and its available flow rate.
  4. On The Grain *Newbie*

    Are you running full power once at temp and are you agitating continuously ??
  5. Bottle Rinsing-Sparging

    Air cleaner is fine BUT I feel that the biggest problem is from dust and storage. Dust will require a liquid rinse but storage is another issue. Have bottles been bulk stored outside (damp and moisture), what are the dividing boards between bottles. If plastic, fine but if cardboard or masonite, then mould is or may be an issue.
  6. What ever happened to iStill?

    How did you go about degassing the BEER. Partial heating and excessive agitation prior to distilling ?? Gas within the beer results in excessive foaming and flooding of the column.

    Hey it's a different and novel approach, but I can not see it working efficiently in that you will not reach acceptable / comparable extract. Basically you are trying to simulate a mashtun and lautertun combination. With beer you agitate the mash and heat for the various conversion steps. Post that it would pass to the lautertun and then onto the wort kettle. So in your case there is no mash for agitation because it has been left behind in the extractor. Also there is no real bed to drain from / through, nor is sparging possible. Ultimately there are going to be terrible losses to contend with. Worst of all, there is is a tonne of spent grain to remove from the extractor. But a great effort and you won't know it until you try it. I have often thought about this and I would have performed all in the kettle and then considered placing a strainer post the kettle whilst pumping / transferring to another vessel for spent grain removal and prior to cooking (wort kettle) and then transferring back to the kettle. That's my sixpence worth.
  8. WARNING: Oak Wood Barrel Co.

    I can relate to this in South Africa. I got caught with a similar scam selling Chinchona bark. Telephone numbers worked, had a fictitious address. Everything was peachy until my money was gone and no delivery.

    Another side to this. YES to easier operations for distiller and I agree to the concept of unattended still operation, but here's another angle. 1 Desperately important to make the same product 100% the same next time. 2 The ability to tweak the still performance for improved operation. And most importantly of all, the process can be left to an underling of less capability. +1 million % important. It becomes a tool of production. Having our cider plant Kegging and bottling totally automated, has resulted in serious quality improvement. This too will shortly apply to our fully automated distilling plant which is also on the LM concept..

  11. Semi - Automation of hybrid still

    I would personally not want to automate this still, specifically because of its small diameter. It's like asking something small to do something really big and this is when things start costing lots of money. My two cents worth would be change to a LM type of collection with dephleg on top and collection below, flowing out through a needle valve to a PC. So the the only items being controlled are the heat and reflux control with the needle valve. Far simpler.

  13. Distilling Cider With High acidity

    Looking at this from a slightly different perspective, if you have copper in the hot vapour path column prior to condensing, is this still an issue or is it only a problem with cooled liquid product.
  14. Mash to whiskey in single run

    Interesting one because you need to barrel at 60%. You have not indicated your wash ABV. I think it is a big ask on a four plate column. Additionally there is going to be a high reflux required which potentaially will be stripping flavour.
  15. New equipment

    I would seriously suggest that you look at Istill.
