The rectification part is supplied in a standard 3-level design. The dephlegmator is made up of a tubular bundle. The catalytic convertor has a copper lining.
Steam enters from the boiler to the bottom part of the column, which serves to separate the foam; it the enters the bottom part of the rectification column and bubbles through a layer of liquid on each of the individual levels. The steam is enriched by the alcohol component and separates itself from the water and other undesirable substances on each of the levels. Each level works as a separate distillation stage. The steam then goes into the dephlegmator and the catalytic converter. Part of the alcohol vapor is cooled in the dephlegmator. Vapors condensed in the dephlegmator create a reflux.
The size of the reflux (cooling of the dephlegmator) governs the entire distillation process. With a large reflux, a distillate of higher alcoholic strength is obtained, and with a small reflux the resulting distillate is weaker.
The catalytic convertor, which releases carcinogenic ethyl carbamates and cyanides from the alcohol vapors, is located in the upper column extension.
For perfect control of the distillation process, the column is equipped with an alcohol vapor temperature sensor, which serves to control the supply of cooling water to the dephlegmator via a solenoid valve. This makes it possible to optimize the cooling water consumption when cooling the dephlegmator and thus facilitates the overall operation. At the same time, it ensures stability and sensitive regulation of the whole process. This is also facilitated by very accurate temperature measurements taken using a digital thermometer.
The operating mode is controlled automatically and does not require supervision.
