These instructions have been copied from the Still Spirits instruction sheets for this still.
To assemble:
Your Super Reflux Still comes complete with 250ml of Still Spirit
Ceramic Saddles
1. Add the Still Spirits Ceramic Saddles to the condenser making
sure that the wire mesh is sitting flat in the condenser chamber.
Fit Bung.
2. Fit the condenser to the domed lid and tighten securely.
3. Situate the still on a firm heat resistant base close by a cold
water tap, drain and power socket.
4. Fit the thermometer so that the bulb appears on the inside of
the black bung by 20mm. Then refit the bung & thermometer into the
top of the condenser.
Distillation using wash made with standard or TT turbo
yeasts:
For a wash made with standard Turbo Yeasts or Temperature Tolerant
Turbo Yeasts, using 7kg Dextrose (6kg Sugar)
1. Pour the wash into the still being careful to leave the
sediment behind.
2. Fit the lid, complete with condenser and hoses, onto the Still.
3. Plug the element in. When the wash has warmed up, but before
thermometer reads 50o C, start the cold water running through the
condenser. (You can start running the water through at the
beginning)
4. During most of the distillation process the cooling water
flowing through the condenser should be flowing at about 500 mls
per minute. To measure the flow, fill a calibrated jug from the
outlet pipe for one minute. nb. 500 mls per minute is the ideal
flow rate for cooling water that is under 20o Celsius. If your
cold water supply is warmer than this then a higher flow rate may
be required alternately cooling the incoming water by connecting
it via a copper tube and submersing this in a container of iced
water.
5. Collect the first 50 mls and discard this. This is the Head. It
is non-drinkable and must be discarded as it may contain
by-products that will substantially reduce the quality of your
spirit.
6. Collect 3 litres of the Body, which contains the Ethanol
(drinkable alcohol) at about 80%/V. Make sure that the spirit
outlet tube from the condenser stays well above the level of the
spirit.
7. If using a standard turbo do not collect more than 3 litres of
distillate. Any spirit collected after this amount will reduce the
quality of your spirit.
8. The more cooling water that flows through the condenser the
lower the temperature in the reflux column, this will show on the
thermometer. The temperature of your water also influences the
amount you need. (i.e. In summer you may need more water than in
winter when the water is cooler). The slower the cooling water
flows through the condenser, the higher the temperature will rise
producing a faster flow of spirit. Running the cooling water at
less than 500 mls per minute may result in a loss of alcohol
through steaming from the spirit outlet. If you run more than 600
mls of cooling water through the condenser then this will slow the
process down.
9. The thermometer temperature will slowly rise as the alcohol is
boiled off. Increase the flow of water through the condenser to
hold the temperature under 92o. The flow will slow toward the end
of the distillation.
From a standard 25-litre wash produced with 7 kg of Dextrose and
Still Spirits Turbo you should collect 3 litres of alcohol at 80%
strength in 4.5 hours. Remember to always measure the strength of
your spirit at 16o Celsius or refer to the Temperature Correction
Chart to make the relevant adjustments. Remember that you have
extracted the alcohol so the rest of the wash contains
fermentation by-products and water and should be discarded. nb.
This makes a fine garden fertiliser but should be cooled before
pouring over your plants.
Points to watch out for:
a. If for any reason the wash has not fermented completely, (i.e.
above 990 SG all the sugar has not been converted to alcohol),
then you will not collect the full amount of distillate through
the Still.
b. If you have not collected the full amount of alcohol, check you
have:
used the correct amount of sugar/ dextrose in the Wash; and/or
the specific gravity is below 990 before distilling; and/or
there is no steam leak during distillation.
c. A typical wash will take about 4.5 hours to run through the
still. It will take about 1 hour and 35 minutes to heat up before
any condensate will run out of the condenser. It will then take
about 5 minutes to collect the Head, and nearly 3 hours to collect
3 litres of alcohol at 80%. This is a rough guide only.
d. If the wash is not fully fermented out, then the unfermented
sugars can foam causing the wash to come through the condenser
with the distillate. In this instance Distilling Conditioner can
be used to increase yield or avoid problems.
