20000L Beer Fermenter
CASSMAN
In large-volume brewing, temperature stability is non-negotiable. Our 20,000L fermenter utilizes a multi-zone glycol cooling system, allowing for precise, segmented temperature management throughout the entire fermentation cycle.
Ultimate Control: Achieve a temperature stability of ±0.3℃, a significant improvement over smaller tanks (±0.5-1℃). This precision allows you to step-mash, diacetyl rest, and cold crash with confidence.
Eliminate Off-Flavors: Prevent incomplete fermentation (high final gravity) and the formation of undesirable esters or aldehydes caused by temperature swings. Guarantee a clean, consistent flavor profile batch after batch.
A large fermenter is a CO₂ powerhouse. Our design helps you harness it.
Stable & Ready for Recovery: The consistent CO₂ production (approx. 0.5-0.6 m³ per m³ of wort) is ideal for integration with a CO₂ recovery system.
Drastic Cost Savings: Harvest and purify CO₂ (to >99.5% purity) for use in carbonation and packaging, reducing reliance on purchased CO₂ by 30-40% compared to systems without recovery.
Protect your beer from its greatest enemy: oxygen. This tank is engineered for the long-term cold conditioning (lagering) that delicate beer styles demand.
Airtight & Pressurized: Built with food-grade mechanical seals and designed to maintain a slight positive pressure (0.05-0.1MPa), the tank prevents air ingress that causes papery or astringent off-flavors.
Perfect for Lagering: The robust design is ideal for the extended cold storage periods (15-30 days) required to produce crisp, clean lagers.
| Structural Component | Key Design & Engineering Features | Process Function & Benefit |
|---|---|---|
| Tank Body & Material | 304/316L food-grade stainless steel. Vertical cylinder (approx. ø2.2m x 11.5m H). Wall thickness 6-8mm, reinforced to 10mm at top/bottom. | Withstands CO₂ pressure (0.15-0.3MPa) without deformation. Inert material ensures no flavor transfer, guaranteeing beer purity. |
| Cooling System | Multi-zone spiral glycol cooling jackets (3-4 independent zones on cone and body). | Provides precise, stratified temperature control for different stages (e.g., 4-10℃ for lager, 15-25℃ for ale) and efficient cold crashing. |
| Agitation & Circulation | Optional side-mounted agitator or bottom magnetic mixer. Integrated CIP and racking arms serve as circulation ports. | Ensures homogenous mixing of yeast and wort for efficient startup. Prevents thermal stratification and yeast settling during maturation. |
| Pressure & Venting System | Top assembly includes dual safety valves (PVRV), an automatic exhaust valve, and a CO₂ recovery port. Pressure control accuracy of ±0.01MPa. | Maintains stable internal pressure to protect beer from oxidation and provide natural carbonation. Safely vents excess pressure and allows for CO₂ harvesting. |
| Sensors & Control | Equipped with 3-4 multi-level temperature sensors, a pressure sensor, and level sensor. Ready for integration with brewery DCS/PLC systems. | Enables real-time monitoring of all critical fermentation parameters. Allows for full automation of cooling and venting, reducing manual oversight. |
Cassman offers a full range of fermenters and brite tanks to fit any production scale.
