1. Drawing and specification.
We offer you a sketch and description of the installation for the production of high-quality alcohol from brew made from sugar or various fruit raw materials.
The design of the installation is simple, does not require large investments. It is quite possible to make it in the conditions of a home workshop or garage for a person who knows how to hold a plumbing tool in his hands. The installation consists of scraps of stainless pipe of different diameters interconnected in a specific sequence by partitions using ordinary soldering or welding and filled with filler.
Any room with a supply of electricity of 220 V and running water for cooling is suitable for operation of the installation. In addition to electricity, you can use other sources of heating: gas or electric. Cooker, cooking stove, hot steam, etc.
The installation can be performed in several versions depending on the performance and power consumption, which is clearly seen from the table:
1. All dimensions are in millimeters.
2. Since the installation can be made of pipes of other diameters, it is necessary that the gap between the pipes (cylinders) of poses № 5 and № 8 be at least 6 mm, and between poses № 4 and № 5 not less than 10 mm.
3. All installation parts are interconnected by ordinary soldering or welding.
4. The distillation column in the upper part has 4 - 8 holes D = 8-10 mm for the release of alcohol vapors into the space between the cylinders of poses № 4 and № 5.
5. Deviations in linear dimensions when assembling the installation has no significant effect.
Note: The above dimensions correspond to the installation capacity of 25-30 liters. / Day. 2. Recommendations for making the installation:
A stainless pipe D = 57 mm (preferably thin-walled) with a length of 1500-2000 mm is taken. The pipe ends are machined on a lathe or plumbing tool. Then, on one side at a distance of 40-60 mm in one cross section, drill 4 - 8 holes D = 8-10 mm.
Prepare cylinders (pos. № 4 and № 5) also from stainless pipes of corresponding diameters. If possible cylinders grind on a lathe, if not then pick up thin-walled pipes.
Partitions poses number 2, number 3 and number 12 are cut out of a stainless sheet with a thickness of 0.8-1.0 mm with metal scissors for cutting and cut with a chisel, followed by processing on a grinding machine or file. The dimensions of the walls and holes D 8 mm in place. Tubes for water and alcohol do not require special preparation and can be of any configuration and length.
We start the assembly of the installation by soldering or welding partitions, pos. Number 3 and pos. 12, on the cylinder, pos. No. 5, on both sides, so that the holes for the water pipes are on different sides.
Next, put the inner cylinder with partitions on the pipe D = 57 mm at a distance of 5-6 mm from the holes D = 8-10 mm and then solder or weld. After that, the tube of item 11 is soldered to the partition of pos. No. 3. Then the outer cylinder pos. No. 4 is put on the inner one so that it rests on the partition of poses No. 12, on the other hand the partition of poses No. 2 is put on, then the details of poses No. 4, No. 2 and No. 12 are joined by soldering or welding. A water outlet tube (pos. 11) is soldered to two parts, pos. №2 and №3. At the same time, solder tubes of poses No. 7 and No. 13 are soldered. Next, the mesh of pos. No. 9 is soldered in the lower part of the tube, pos. No. 8. The space between the cylinders №4 and №5 remains empty and is a refrigerator for alcohol vapors. The space between the pipe D = 57 pos. No. 8 and the inner cylinder pos. No. 5 is intended for the flow of cold water under pressure, thereby cooling the alcohol vapor in the reflux condenser (empty zone in the pipe D = 57 item No. 8) and in the refrigerator.
After all the connecting operations are completed, the installation must be pressurized. For what it is necessary to drown the pipe D = 57 pos. No. 8 on both sides of the corks or plugs, fill it with compressed air through a pipe to release alcohol pos. No. 13 and anoint all sutures with soapy water. If any seam misses, bubbling will be visible. Pressure testing of the water cavity is made easier. Connect the pressurized water to the water inlet pipe, plug the water outlet pipe. Water should not leak through the seams and even less to flow or drip through the alcohol outlet pipe. Crimping is over. Now the installation is attached to the tank 40 - 200 liters in various ways, we connect the hoses for water. Hoses it is desirable to have polyethylene D / y = 8 mm.
Cans, pressure cookers, cans, milk flasks and other containers made of stainless steel or edible aluminum are used as containers. If you choose a gas stove as a source of heat, it is necessary that the installation and the tank be not high and the whole building fit in height in a house or apartment. If the source of heat is electric energy, it is necessary to install 2–4 pieces of different power in the bottom of the tank so that it is possible to regulate the boiling process. For example, 2 - 3 pieces of 1 kW. and 1 pc. at 0.5 kW. The tank should be sealed, have a filler neck, a valve to drain the mining and a tube for the thermometer.
After everything is ready in the pipe D = 57 pos. No. 8, a filler is poured through the top, a heat insulator is inserted and the stopper is closed.
3. Description of the installation:
A brazhka or other alcohol-containing raw materials (house wine, beer, off-spec vodka, etc.) are poured into the container through the throat and heated. When the temperature of the mash increases to 80 ° C, the heating rate is reduced and such a stable boiling is achieved so that the heating is fully controlled. At a temperature of 82-84 ° C, the installation will fully warm up and raw alcohol will flow from the alcohol outlet pipe (high degree home-brew to 96 o). The rate of release of raw alcohol depends on the heating of the brew. In the distillation process, the temperature of the mash increases. Temperature controlled by thermometer, which is inserted into the tube on the tank. The tube is plugged on the inside. Before inserting a thermometer, pour water or vegetable oil into the tube. When the temperature reaches 98 ° C, the distillation must be stopped because at this temperature, there is almost no alcohol left in the braga, but intensive evaporation of fusel oils begins. Distillation can be completed at a lower temperature, but then some of the alcohol will remain in the brag, and the amount of fusel oils will decrease.
Note that the resulting raw alcohol is significantly different in purity from ordinary moonshine, but it is recommended to clean it to obtain high-quality alcohol. You can not clear, it all depends on the subsequent actions, because With further distillation, an "automatic" purification of alcohol occurs. It is enough to overtake two times (brago for alcohol - raw, and its pure alcohol). But some factions (not enough quality) are distilled several times.
After the primary distillation, it is necessary to drain the treatment from the tank and rinse it. To obtain alcohol in the tank instead of the mash load purified alcohol - raw (diluted with water to 40 - 60 o) and heated. When the temperature reaches 76 ° C, the heating rate is reduced and slowly brought to 78 - 82 ° C (boiling point of alcohol). After a while alcohol will flow. The first fraction obtained, the volume of which is about 3-8% of the volume of alcohol (40 ml per 1 liter of 45 ° crude alcohol), is subsequently used only for technical purposes. It contains boiling impurities. The speed of alcohol should be such that the fortress was 96 o. Distillation to a temperature of 100-101 o). When the temperature reaches about 88 - 95 ° C, the rate of flow of alcohol will decrease and a characteristic unpleasant odor will appear. In this case, it is necessary to increase the heating rate in order to quickly leave the remains of alcohol, which is to be re-distilled with a new volume of alcohol - raw. The middle fraction should be of excellent quality, with a strength of 96 o, and it is used as intended.
