FRACTIONAL STILL – HIGH QUALITY LIQUOR.
The construction of fractional (reflux) column makes it possible for the ethanol to be re-distilled inside the column for more than 30 times before it reaches the collection vessel ( this ability of column gives us the strength of alcohol of 95 - 96% alc/vol). The correctly built fractional column creates some fractions' queue inside the column where the lightest spirit fraction is locating at the top of the column and get collected while the most massive alcohol fraction is yet located at the bottom. The light alcohol is collecting the next in the queue, and more heavier one is replacing the lighter one and so on (this ability of column gives us the high quality of alcohol because one can separate and collect all fractions one after another very precisely.
The 25L fractional homebrew still has all you need to perform precise distillation; it has one small column for raw spirit production and the big fractional column for high-quality food grade ethanol production. The small column also can be used along with infuser or by itself for an aromatic beverages production where you can redistill alcohols that were soaking with herbs or fruits, ( I used the small column to make absinthe).
The whole still arrangement that includes two columns is designed to produce high-quality ethanol at highest percentage possible. There are two columns: the first column is intended to deliver a low-quality spirit from the fermented wash (mash, beer, wine...) and works as a pure pot still. The primary purpose of this column is to separate spirit from the wash.
The second, (fractional) reflux column (has the option of manual reflux ratio control that does not depends on cooling water flow speed or temperature) is designed to fractionally separate all the impurities from the low-quality spirit that we get after the first distillation.
The fractional column is used only for crude alcohol - or moonshine quality redistilling and separates all impurities physically from ethanol.
Thus with the help of fractional column you can get all fractions precisely defined, and during distillation, you will rely on mathematical calculation of spirits amounts that based on fractions percentage calculation - this means that you will know of how much of each fraction you are going to get even before starting your distillation.
If you are familiar a bit with some reflux columns, you could know that basically, all reflux columns are capable only to produce the spirit with the relatively high percentage of alcohol in the spirit/water mix and not capable of separating any impurities. Plus the percentage of the alcohol drops during the distillation, and the reflux ratio (sending back into the column or condensing some spirit inside the column for repeated distillation). The percentage and the quality of alcohol are achieved and controlled by the speed of cooling water flow - believe me, it is almost impossible to accomplish any good quality results with this type of distillation system.
You are going to get out of simple reflux type of still just what it is capable of giving you. The distillation system that is described on this page is real fractional distiller where one can control reflux ratio and spirit speed flow regardless of water flowing rate. In fact, the spirit collection/flow control valve can be closed completely, and column will utilize all spirit back into column's internal space, and no pressure build up will ever happen.
All fractions get separated accordingly to their physical properties plus this fractional distiller will give you a maximum possible percentage of spirit: 95%+ from the start of distillation to the end of distillation. In fact, all impurities that you will get from this still can be used to power four stroke engines (I use it for my lawnmower).
Just a few words about filtration: some people believe that activated carbon can absorb impurities such as methanol or butyl alcohol, this is not right. One can run the bottle of methanol through the activated carbon filter and get the same poisonous methanol from the other end of the filter. It will be sparkling clean, but there In fact, if activated carbon's pores are big enough for the water to run through then they are even bigger for anything that more liquid than water. All the carbon does is absorb the odors and mechanical particles (cloudiness). I prefer the activated carbon that is made out of coconut shell over the carbon produced out of peat, guess why?
Some people believe that during filtration the spirit must be in contact with activated carbon for at least 45 minutes, (back in the army I used to use the gas mask with activated carbon in the filter cartridge, and no one was breathing in for 45 minutes. We were breathing as usually, and carbon did the job. In reality, you can even use the pressure pump to boost the filtration process (all vodka companies are using the pumps to increase the filtration speed) but make sure that your filter is loaded correctly and tight.
Never filter undiluted spirit, the carbon works only up to 60% spirit strength, it is simple - the water that is added to the alcohol during dilution is bounding up with some impurities, and the carbon keeps this bounded up molecules. Undiluted spirit will just run through the carbon.
Here is some facts:
Here is are some facts to Save your $$$ on distillation!!!
The fractional distiller can also be used and ordered as a water purifier and essential oils extractor, the still can be used for a small scale fuel ethanol production.
