Purpose |
The gas analyser IR-SD
2/2 is designed for simultaneous online determination of the actual ethanol concentration
during alcoholic yeast fermentation in two fermenters. The system enables the observation
of ethanol formation in real time without sampling and the detection of the termination of
fermentation (batch Operating range: selectable between 0 – 15 vol% ethanol Precision: ± 0,2 vol% ethanol Reproducibility: ± 0,05 vol% ethanol |
Function
|
Instrument air is conducted
through a probe placed in the fermentation mash. The probe is covered with a silicone
membrane so that the air stream while passing the probe is enriched with ethanol diffusing
through the membrane. Detection of ethanol is performed by an IR-sensor which registers a
signal depending on the ethanol concentration. From the signal change compared with zero-calibration, the corresponding alcohol concentration in the fermentation mash is calculated. Measured raw signals are transmitted to a multifunction module where the actual alcohol concentration is calculated considering actual fermentation temperature and vapour pressure effects eventually resulting from the raw material. The linearised signal is converted into a standardized current signal (0/4 - 20 mA) which is displayed as ethanol concentration at the multifunction unit on the switchboard directly and can be used as input signal for any PCS (Process Control System) or flow controller (remote setpoint operation). Determined calibration data can easily be transmitted to the multifunction unit.
