Subject: [new_distillers] Gen.quary on boiler jacketed stills and steam
Howdy Hi all, I posted pretty much the same question awhile back , but got
no real answere in return. Even tried to get some anseres from
Biofuels@... but no luck there either, so I will try again.
I,m building a boiler jacketed still, my boiler jacket is 17"x!7" made from
316 S.S. and is 3/16inch thick. Both top and bottom plates are 6 gauge 316
My distillation tank is made out of 14 gauge 316 S.S. And is 8"x 34" and
will hold 5gals. of heavy grain mash or fermented fruit pulp. The tank will
sit 4" above the bottom of the boiler tank.
The first question is will my boiler jacket be big enough to heat 5 gals. of
Second question I can or will use 2- 4500wt. emersion heater elements would
these be better placed at the bottem or midway in the boiler jacket ? The
jacket will be insulated with 2" of insulation and have a S.S. protective
sheild around it.
Third Question should I add a water circ. pump and a water preheater?
Question 5 would a steam injection device be of any help in heating the mash
or would this be a over kill. I have all the safety valves and
regulators, temp and presure gauges.
One of the beer brewing guys might be better at answering this (have you
tried their lists?), but there may be someone on this list with direct
experience of what you propose doing. I'm just shooting in the dark here.
I'm left scratching my head over the dimensions you give, but assume that
you will have the "distillation tank" sitting inside the "boiler tank" and
plan to distil directly without first straining off solids. My return
question to you is "why?" Does anyone know if this is a practical
technique? My personal preference would be to strain the solids off, with
washing to do a thorough job, then deal with the resulting liquid in a
conventional boiler. Unlike beer brewing, it doesn't matter if you add
extra water in the washing process.
The power of your heater elements seems rather high too ... 9 kW. It willl
certainly heat up fast, but will it be controllable once it is boiling,
wherever you put the elements? With the turbulence from such massive
heating, I doubt very much whether you would need a circulation pump.
Steam injection is for experts. It is very efficient, and is the usual
commercial method for heating, but it can be rather dangerous in an amateur
setting. Despite all the safety valves etc you have, please bear in mind
that steam is unforgiving and can result in nasty accidents.
Sorry if this doesn't help much, and I may have missed the point entirely.
Anyone out there with better knowledge?
