Отгон емый из этой фракции дистилл т по чистоте соответствует дистилл ту, отбираемомуRodvigatel 11 through the gearbox. A distribution disk 12 is located in the upper part of the housing of the apparatus, and there are also nozzles - a vacuum 13 and a power supply 14, in the middle part - an additional power supply 15. The bottom of the apparatus is equipped with pockets 16 and 17 for collecting distillation products and tapping fittings 18-20. Similar pockets 21 and 22 are located in the middle part of the condenser, fittings 23 and 24 are brought inside the condensation cylinder. Moreover, inside the device under the fitting 15 and the collection pocket 21 the distillate between the rotor bar and the evaporator is annular, not in the pocket 17 together with condensate that drains from the grid 5, is discharged through the nozzle 20 and is fed into the upper part of the distillate J-torus through the nozzle 14 of the power supply to the distribution disk 12, then flows down to the evaporation surface of the first zone, is heated and rubbed into thin her film. Distilled from this fraction distilled for purity corresponds to the distillate selected

The molecular distiller operates a phase input and output device, and differs as follows.

The initial product through feed shtucer 15 enters the heated surface of the evaporation cylinder and is spread on it by spreading elements 3. The liquid on the evaporator heats up, evaporates, the steam partially condenses on the splash guard 5, the rest

In order to simplify the design and increase the yield of the pure fraction of the distillate, it is equipped with an additional input device located in the central part, made in the form of a choke and located below the inner surface of the evaporator wall of the distribution chute.

2. Distillate from the condensation surface of the second zone (pure fraction) flows through the nozzle 24 into the pocket 22 and further into the internal cavity of the condensation cylinder, from where it is led through the fitting 19 to the collection of the finished product. The non-evaporated product passes through the evaporator to the third distillation zone, where a second fraction is distilled off from it, containing

along with the low-boiling product, impurities of high-boiling components. It accumulates from the second zone, therefore, as it accumulates in pocket 21, it flows through the clamp 23
