The latter is integrated between the evaporator and the compressor and is composed of two accumulators, a heater, and a rectifying column
. When an increase in the capacity of the HP is required, the expansion valve opens and the accumulator above the rectifying column
is partially filled with liquid refrigerant.
- Part 2 Set vacuum distillation plant comprising a thin layer of vacuum and a vacuum distillation unit with a rectifying column
for laboratory use,
column still: tall, metal still of one (analyzing column), two (rectifying column
), three (hydroselection column) or four columns in which a fermented mash is boiled to produce vapors which, once condensed, are distilled into a spirit of at least 60% alcohol by volume (abv) and as much as 95%, depending on how many columns there are.
Section 9 - Set vacuum distillation plant comprising a thin layer of vacuum and vacuum distillation installation with a rectifying column
for laboratory use;
