The fundamental difference of this distiller is that in the column installed directly on the cube, the so-called "reflux condenser" is mounted.
Structurally, it is a radiator with a constant supply of cooling water, with through pipes through which all the steam rising from the cube passes. Due to the fact that in contact with the colder walls of the pipes, all the water contained in this steam condenses, as a result we get steam with a maximum alcohol content and, accordingly, with a minimum content of all other impurities, which significantly worsen the quality of the distillate.
The fundamental difference between a reflux condenser and a distillation plate, which performs a similar function, is that the plate, being under the constant influence of steam, heats up, and the phlegm condensing in the plate, heating up, in addition to alcohol, passes more and more impurities. But we strongly recommend using a distillation plate together with a column with a reflux condenser to get the maximum cleaning effect.
It is this design of the column (rectification plate + reflux condenser) that will allow you to maximally purify the alcohol contained in the mash from fusel oils, the main component of which is isoamyl alcohol. By keeping the water temperature at about 85°C-90°C, isoamyl alcohol will not be able to pass the reflux condenser, since its boiling point is 132°C and it will not reach the radiator, where it could condense already in the finished product.
The water used in the dephlegmator for cooling is supplied from the top of the radiator, already heated in the process of cooling the vapors in the radiator itself. In this way, optimal water consumption and application is achieved..
Schematic representation of the dephlegmator:
P - the flow of alcohol-containing steam from the moonshine still
C - alcohol-containing steam without heavy-boiling components (sent to the coil)
K - condensate of heavy-boiling components (fusel oils, we clean the future distillate from them)
T - heat transfer by alcohol-containing steam through the surface of the dephlegmator
B - water for cooling the dephlegmator supplied from the radiator
W - heated water drained from the dephlegmator.
Attention! The water temperature can reach up to 95°C!!!
As a result, thanks to the use of a reflux condenser, we get a quality that is not worse than after secondary distillation, without increasing the cost of labor or time.
To determine how much pure water to add to a distillate with a higher alcohol content to get a 40% drink, you need to divide the current alcohol content by 0.4. For example, 750 ml should be added to a 70 ° distillate. water for every liter of distillate to get 40°. (0.7 / 0.4 \u003d 1.75, i.e. in the end, you should get 1.75 liters of the finished product).
