sure that there is no steam coming out anywhere – check carefully at the
top column, as it can be hard to see. You will need to increase the water
flow a little if there steam at the top of the column. Check that there is no
steam leaking around the lid of the boiler or anywhere else. A VERY small
of vapour leaking anywhere will result in a LOT of alcohol loss. You should
be able to smell it. Measure how fast the alcohol is coming out of the still.
If it is coming out faster than 1.5L per hour, then it will need to be repaired
– contact your dealer. Make sure that before distilling the wash, that it has
completely stopped bubbling, and use a hydrometer to check that it is
between 980 and 990. If not, the wash has not produced the correct
amount of alcohol. If none of these fix it, then try pushing the mesh further
into the column about 2cm. DON'T REMOVE THE MESH. If this doesn't
work, consult your dealer for advice.
If there is steam coming out of the top of the still
Cooling water is too slow – increase the flow a little until the steam stops. If
you are using a water pump, it may not be powerful enough. You need a
pump capable of at least 3000L/hr or a max head height of 3m.
If the product still comes out hot
This is not normal for this type of still. It helps to evaporate any light
volatiles that can cause smells and tastes.
If the product is coming out very slow
This still set is to run are around 1.2L per hour. After you have
opened the tap, you would expect it to take around 40mins to get to
800mL from 5L boiler, or about 3 ½ hours to get 3.8L from a 25L
boiler. Measure the output by placing a 1 cup measure (250mL)
under the output with it still running. Time how long it takes to fill –
it should take about 12 minutes. If it takes longer than this, then you
will need to clean the orifice.
