Dual Stage Exhaust Air Washer / CONDENSER for Vinegar Production
Cetotec dual-stage exhaust air scrubbers offer, especially for industrial vinegar fermenters and larger quantities of exhaust air, the ideal solution for cleaning the air and recovering valuable resources at the same time. Cetotec condensers can retrieve valuable volatile and aromatic substances from the exhaust air. The recovered liquid is available in concentrated form and can be constantly reintroduced into the fermenter. Condensers are especially recommended for the production of speciality vinegars. For further increasing the yield, condensers can be used in combination with an exhaust air scrubber.
The robuste and compact design of the absorber column and absorber reservoir is complemented by a reliable automation system. The exhaust air, consisting of ethanol and acetic acid is transported through the absorber column and thereby cleaned. By using a dual-stage exhaust air scrubber, the exhaust air is passed through two washing columns in succession, thereby increasing the recovery of volatiles to more than 90%.

Advantages
- Recovery of over 90% of exhaust air resources
- Reducing emissions below 50 ppm
- Minimizing odor emissions in residential areas
- The droplet separator reliably prevents the egress of acetic droplets
- All-stainless steel construction
- Suitable for both indoor and outdoor installation
Functions
The exhaust air scrubber functions on the basis of physical absorption. The resources contained in the exhaust air are washed out of the gas phase and gathered within the washing liquid. The special design of the filling material within the absorber column guarantees a very high surface and therefore leads to an optimal mass transfer during the cleaning. The washing liquid can be used for mash preparation or dosed back into the vinegar fermenter. In case of using the fed-batch process the liquid can be dosed into the fermenter during the charge phase.
