  1. I wish you the best of luck on your journey. There are only two companies in the USA that make continuous columns. One of them has been making the same model (construction) for 100 years already Only different sizes I see that the alcohol and whiskey industry is very conservative. Everyone is satisfied with the "big shining tanks" of steel and copper. Nobody thinks that you can get three times the distillation rate from the same place in the room.
  2. I completely agree! I have been in Automated Control and Embedded Systems for over 20 years, and I am a "very trained pessimist" when it comes to electronics and automation applications. In addition, all developers of "remote control" for some reason forget that Wi-FI does not have a guaranteed data delivery, and is very dependent on the level of external interference. (Especially from spark interference) And the Internet Protocol TCP/IP itself does not guarantee the delivery time of the data packet at all, does not guarantee the delivery of the data packet itself, does not guarant
  3. Hi! I want to give my opinion if you are interested. 1) for the US market, it is required to comply with the conditions of fire safety requirements, in particular, hot alcohol and electricity are very dangerous. This falls under the zoning: C1D2. Therefore, any electronics that do not have a UL listing requires special permission and inspections and examinations. Therefore, all electronics "not UL listing" can only be used by small manufactures "for themselves" and at their own peril and risk. Therefore, your electronics cannot be applied (and sold) to large alcohol factories.
  4. Hi Ryan! Welcome to the forum Will you buy ready-made equipment for the production of alcohol and vodka, or will you design the equipment yourself?
  5. It is pointless 🙂 Packings (filling, backfilling) inside the column play the role of increasing the area and smoother distribution of the temperature difference over the height of the column. Main problems: 1) The fill column cannot act as a stripping column because solids will clog all the passages. 2) with a large diameter of the column, there is a big problem of uniform distribution of reflux over the diameter of the column and the vapor velocity upward along the diameter of the column. 3) in the column "with filling" (nozzles are filled up) it is impossible to
  6. The middle esters are formed at elevated (more than 40 ° C) temperatures and when acidic esters are heated. The middle esters are insoluble in water, but readily soluble in hydrocarbons and organic solvents. Under the action of water or an alkali solution, the middle esters can hydrolyze to form first alcohol and alkyl sulfuric acid, and then alcohol and sulfuric acid 🙂 Esters of wines and cognacs are mainly represented by esters - products of substitution of hydrogen atoms of OH groups in mineral or carboxylic acids by hydrocarbon radicals. They (esters) are involved in
  7. My advice to you: if you want to work (preserve) grain and fruit aromas (esters) and tastes, then you need to apply vacuum distillation. No other distillation methods will give such capabilities and product purity from fusel oils and "stink". One of my friends lives in Georgia (Country on the Black Sea, not a state in the USA) he has a large harvest of tangerines every year. He makes tangerine mash, and then distills it. When I sold him my vacuum distillation controller and told him how to get flavors, he got amazing spirits In Georgia, distillers compete to make a purer alco
  8. To be honest I personally do not understand at all the desire of people to use copper for catalysts. Copper gives off a "bouquet" of medium ethers, I have seen this many times on chromatograms. As soon as copper is used, it does not matter - like plates, like an alambic, or like tubes of electric heaters inside the tank, so the parameters "average ethers" in the chromatogram will always be one and a half to two times higher. Higher compared to pure steel tank and heaters. The most difficult thing in all this is that each person is very sensitive to "average ethers" in his own way.
  9. A little information 🙂 Colloidal copper. This is one of the main trace elements that are involved in the vital processes of the human body. It is one of the components of human blood and plays a very important role in the oxidation of vitamin C. Among non-ionic colloids, copper is today the strongest fungicide and disinfectant. This is the first Materials in an ultrafine state (dimensions of the order nanometers) have specific properties, which are due to the peculiarities of the formation of the structure and the presence of a large number of atoms located on the surface of the nan
  10. I will support Paul. The use of "catalysts" (special devices) inside the steel tank is the best price-quality option. From the point of view of Chemistry and Physics, in order for chemical reactions to occur with maximum efficiency, it is necessary to provide the largest possible contact surface of the substance-catalyst, and to provide a temperature higher than the "temperature of the beginning of catalytic reactions". That is why catalyst inserts must be in the path of alcohol-water vapor at temperatures above 70 Celsius. Copper does not work below 70 degrees Celsius. The s
  11. My point is that if you do distillation (no matter what liquids or oils) you need to work with heaters or coolers. In any case, if you need to turn water (alcohol) steam into a liquid, you need to take away thermal energy from the steam and direct it somewhere. It can be cold water, it can be atmospheric air. But it should be remembered that water has the highest heat capacity, so water is very well suited for transferring heat energy. Your vehicles are water cooled. Why? because it allows for compact cooling devices. If you have a motorcycle you can estimate how much its cooling
  12. Milking yeast is not a fantasy. Introduction. Classical fermentation (wort fermentation process) is a familiar process. Bacteria (yeast fungi) eat up sugar and release carbon dioxide and ethyl alcohol in the process. Everything is very good, but yeast eats sugar and defecates with alcohol at the same time 🙂 And then we boil the mixture together with the bacteria, kill them, and release alcohol and with it the by-products of the yeast's vital activity, including "heads", "tails" and various toxic substances. What if you don't kill the yeast? We don't kill a cow when we want mi
  13. "Rectification" (from Latin "rectus" - direct and "facio" - do) is a process of separating double or multicomponent mixtures due to countercurrent mass transfer between vapor and liquid. Rectification - separation of liquid mixtures into practically pure components, differing in boiling points, through repeated evaporation of the liquid and condensation of vapors. This is the scientific definition of the term "rectification". From the point of view of this description, distillation in a pot (moonshine still) is not rectification, but is a simple separation of a mixture of different alc

    I describe (below) what simple equipment you need to buy in order to conduct tests and start moving into the topic of vacuum distillation. You need to provide: 1) tightness. Not all devices are equally gemetichny for excess and negative pressure. Tanks that withstand + 100kPa (+ 1 atm) may not withstand a vacuum of -50kPa. My first device, has a wall thickness of 1.5mm stainless steel and a volume of 20 liters, the bottom and the top cover are flat, because of this, under vacuum, I got the bottom and the cover 5mm inside the tank. The walls (cylinder) stood. 2)
