Products Description

What are the key parameters in the design and operating procedures of a glass molecular distillation apparatus?

Installation of the feeder and receiving bottles: firstly, the feeder needs to be installed (screw the feeder clockwise) as well as the primary, secondary and tertiary receiving bottles, and the cooling water circulation button needs to be switched on.

Adjustment of the film scraper rotor: Open the film scraper rotor and adjust it to the speed, but not more than 400 r/min.

Vacuum pump use: switch on the vacuum pump after the liquid nitrogen reaches the required level (not less than 1/2 of the condensation column volume). When the pressure no longer drops, adjust the vacuum pump trimmer valve to ensure that it does not fall below 0.5 mbar.

Control the liquid level of each effect separator: it is necessary to strictly control the liquid level of each effect separator to make it in the position required for use.

Prevent clogging phenomenon: in the molecular distillation device is easy to precipitate crystalline materials, easy to occur pipeline, plate evaporator, valve and other clogging phenomenon, need to use vacuum pumping or regular water flushing to keep smooth.

Adjustment instrument: often adjust the molecular distillation device instrument to make it sensitive and reliable.

Vacuum operation: molecular distillation apparatus is usually carried out under vacuum conditions, which helps to reduce the operating temperature, reduce heat loss, and improve the separation efficiency.

Heating the mixture: the mixture to be separated is heated above its boiling point to evaporate it. Heating can be by an external heat source or by a heater.

Vapour enters the molecular sieve column: The vapour enters the molecular sieve column, which is filled with molecular sieves, which can be selected with different pore sizes to facilitate the separation.

Thin distillate film, high heat transfer efficiency: the thickness of the distillate film is less than 0.5mm, which can improve the heat transfer efficiency.

Higher degree of separation:glass molecular distillation can separate substances that are not easy to separate conventionally.

No boiling and bubbling phenomenon: glass molecular distillation is free evaporation on the surface of the liquid layer, which is carried out under low pressure, and there is no dissolved air in the liquid, so the whole liquid can not be boiled during the distillation process, and there is no bubbling phenomenon.

These key parameters cover a wide range of aspects from equipment installation, operating procedures to maintenance to ensure the effective operation and efficient separation of the molecular distillation apparatus
