Project Cases
Complete White Vinegar Technology Guide
White vinegar (also known as alcohol-based vinegar) is produced from diluted neutral alcohol. It is widely utilised as an acidulant and preservative within the food-processing industry.
We deliver process design and equipment for vinegar production for capacities starting from 4,000 litres per day.
Key Figures for Vinegar Plant Construction

Aelt Process for Vinegar Production from Pure Alcohol
Acetic acid bacteria convert ethanol into vinegar. Following a maturation phase, the vinegar must be clarified via clarification and filtration steps.
Mash Preparation
Raw-Material Handling
Inside the feed tank, pure alcohol is diluted with process water to a maximum concentration of 15 % and mixed with raw vinegar containing acetic acid bacteria. Nutrients and a small volume of vinegar are blended in a nutrient vessel before being transferred into the feed tank for further dilution and mixing.
This mash is prepared in batches one to two times per week in one feed tank, while a second feed tank serves as the supply reservoir for fermentation.
Vinegar Fermentation
Bioreaction
Fermentation is operated in semi-continuous mode. The alcoholic mash is aerated inside the fermenter by our proprietary IP-8 self-priming aeration system. The fermentation cycle terminates when the vinegar concentration reaches its maximum and the alcohol content drops to approximately 0.3% by volume. Then around one-third of the contents in the fermenter are pumped to the discharge tank.
The fermenter is replenished with fresh mash from the injection tank for the next fermentation batch. One batch cycle takes roughly one day, with the exact duration subject to the alcohol content of the raw material.
Nutrients Aelt
Nutrients are essential for optimal growth of acetic acid bacteria. Nutrient blends are selected according to raw-material type to improve substrate nutritive value and raise process yield.
For white-vinegar production, glucose together with Acetic acid bacterial nutrient blend a proprietary formulation rich in vitamins, minerals and other nutritional components — is added to the mash.
Maturation, Clarification and Filtration
Product Separation & Polishing
Freshly produced raw vinegar drawn from the fermenter undergoes maturation over several weeks inside the discharge tank. During maturation, turbidity-causing impurities such as bacteria, coagulated proteins and precipitated salts settle at the tank bottom.
If required, clarifying agents may be dosed in dedicated clarification tanks for further polishing of raw vinegar. Matured vinegar passes through filtration modules to remove residual solids. Prior to bottling or bulk loading, it goes through sterile-grade filtration and is diluted with process water to target concentration.

Fully-Automated Fermentation
Process Control
Aelt fully-automated vinegar fermentation incorporates sensor-equipped measuring systems for on-line alcohol-content monitoring of fermenting mash.
Alcohol concentration is continuously tracked throughout fermentation. When the preset residual alcohol level is reached, raw vinegar is discharged automatically and fresh alcoholic mash refills the fermenter.
Emergency power supply with auto-start capability guarantees uninterrupted fermentation in case of power outages.
Custom-Engineered Solutions
Our services can be tailored to your requirements. We offer design and supply ranging from key components (fermenters, aerators and process-control systems) up to full-scope EPC solutions for complete production lines including instrumentation & control and laboratory equipment.
Our specialists can also upgrade or revamp existing facilities and integrate vinegar-production units into other manufacturing sites, such as alcohol-production plants.
Cooling Requirements
Fermentation is an exothermic reaction, making cooling critical for stable operation. Cooling water supplied at 24 °C (returning at 27 °C) removes process heat and is decisive for reliable vinegar manufacturing.
Aelt proprietary design features finely balanced internal cooling-coil assemblies installed inside fermenters. (Image: interior view of fermenter vessel.)
