3 Overview

The DE-1626 is a steam distillation, mainly designed to obtain the distillated from
sample for later meassuring the %Vol (alcohol contents). The unit is validated accord-
ing to CEE nº 2676/90 (wine analysis) and CEE Nº 2870/2000 (high degree drinks
analysis) for alcohol degree determination.
The DE-1626 yields a fast steam distillation and an efficient recovery of volatile sub-
stances, as alcohol and acetic acid.
As the DE-1626 will esentially be used for alcohol degree determination, this proce-
dure is given in high detail on the chapter 11. Chapters 5 and 6 describe the general
operation of the unit and how to obtain the distilled from samples.
The unit has the following systems:
The steam generator
Generates steam from the water reservoir placed at the top of the unit.
The steam generator includes a Safety thermostat that cuts the electrical power
to the heater when overtemperature is detected on the steam generator (probably
for poor level of water) and a pressure switch that cuts the electrical power to the
heater, when there is an overpressure on the steam generator.
Also includes a conductivity sensor to keep a constant level of water in the steam
generator.
The distillation circuit
It is mainly made by glassware:
• The rectifier: with a special design to concentrate the volatile substances.
• The two stage coolant: it condensates the steam leaked from the sample. This
glassware is cooled with a external water circulation that is automatically open/closed.
Automatic stop and addition for leveling
Made by a level sensor device and a valve that closes the distillied output and allows
collector flask leveling.
Addition valve to adjust
level.
