External Condenser Vacuum Distillation Machine / Alcohol Distillation Equipment With Wiper Basket

Room temp - 200 / 300 ℃ Vacuum Distillation Machine for CBD / THC / Hemp oil

—— Design

Wiped Film Evaporators are horizontal evaporator with wiper basket, gear motors and external condenser.
The vapour nozzle is typically arranged at the upper end of the evaporator in order to facilitate the transfer of the vapours to the external condenser.
Dea offers thin film evaporators from 0.058 to 3 m2 .

—— Particular features

Continuous distillation process.
Low operating pressures (100~10000Pa ,100Pa=1mbar).
Short residence time.
High evaporation rates.
Processing of high-boiling, high-viscosity or crystallizing products is possible.
Can be used as a reboiler for column.
Low fouling on evaporator wall.

Industrial-scale vacuum distillation has several advantages. Close boiling mixtures may require many equilibrium stages to separate the key components. One tool to reduce the number of stages needed is to utilize vacuum distillation. Vacuum distillation columns typically used in oil refineries have diameters ranging up to about 14 meters (46 feet), heights ranging up to about 50 meters (164 feet), and feed rates ranging up to about 25,400 cubic meters per day (160,000 barrels per day).

Vacuum distillation increases the relative volatility of the key components in many applications. The higher the relative volatility, the more separable are the two components; this connotes fewer stages in a distillation column in order to effect the same separation between the overhead and bottoms products. Lower pressures increase relative volatilities in most systems.

A second advantage of vacuum distillation is the reduced temperature requirement at lower pressures. For many systems, the products degrade or polymerize at elevated temperatures.
