lagertanks

Lagertanks are temperature-controlled storage vessels used to mature or age liquids, most notably lager beer. They are also employed in winemaking, dairy, and other food and beverage processes where extended storage, settling, or stabilization is desired.

Construction and features: Most lagertanks are stainless steel (commonly grade 304 or 316) with smooth, sanitary interiors designed for easy cleaning. They are jacketed or fitted with cooling coils to enable precise temperature control, typically using glycol or chilled water. They include CIP/SIP capabilities, venting, pressure relief, and fittings for sampling, draining, and transfer. Tanks may be horizontal or vertical and can have flat or conical bottoms with discharge valves. Many designs allow inert gas blanketing to minimize oxidation.

Operation: In lager production, beer is stored at low temperatures for weeks to months to promote maturation, clarify the liquid, and mellow flavors. The controlled environment helps stabilize aroma and reduce unwanted turbidity. In other applications, lagertanks serve as aging or settling vessels, storage of finished products, or blending and conditioning steps.

Standards and considerations: Hygienic design, cleanability, and compliance with food-grade standards are central. Selection depends on production scale, target temperature range, and integration with other equipment such as CIP systems, chillers, and automation.
