The device for distillation of liquid contains a distillation cube, a dry cooler and a refrigerator connected in series by a product pipeline. The drycube consists of a bottom and a lid, between which a spiral tape with several turns is vertically arranged, the outer of which is hermetically fixed between the bottom and the lid, and all other turns have a lower height and are evenly spaced to its center, where the nozzle is installed, which is placed above the inner surface of the bottom so that it overlaps the level of the lower edge of the spiral tape, which has a gap with the bottom, the spiral tape with the upper edge of all inner turns is hermetically fixed to the lid, and the last turn – to the bottom near the protrusion of the spigot. The outer coil has a flat bend, on which there is a fitting for connecting the dry cooler with the refrigerator. Tightness of all connections is performed by soldering, welding.
