Stainless Steel Mash Tun

The Stainless Steel Mash Tun is the foundational vessel of the commercial brewhouse, engineered for mashing crushed malted grains with temperature-controlled water to convert complex starches into fermentable sugars. This heavy-duty vessel ensuring precise thermal management and maximum extract efficiency for craft breweries, microbreweries, and commercial beer production lines. Constructed from premium-grade sanitary stainless steel with advanced insulation, it delivers consistent batch-to-batch brewing performance and high wort clarity under rigorous daily operations. 

Maximised Extract Yields: The combination of scientific raking profiles and optimized false bottom spacing increases brewhouse efficiency by up to 5% to 8% compared to standard generic tanks.

Anti-Scorching Thermal Protection: Low-watt density electric elements or dimple-jacketed steam heating systems are designed to prevent wort caramelization, protecting subtle flavor profiles.

Reduced Labor Costs: Automated spent grain removal and integrated CIP cleaning cycles significantly decrease turn-around times between batches, allowing more brews per day.

Uncompromised Food Safety: 100% TIG welding with argon gas shielding ensures smooth, crevice-free internal welds that completely eliminate bacterial harborage.

Scalable Engineering: The modular structural design allows seamless integration into existing brewhouse configurations or future multi-vessel expansion plans.

Hydration & Mixing: Grist and hot water enter the vessel simultaneously through a top-mounted grist hydrator, achieving immediate uniformity without dry balling.

Enzymatic Conversion: The temperature is held precisely or stepped incrementally using the heating jackets. The automated raker rotates at low speeds to maintain thermal equilibrium without shearing grain husks.

Wort Separation (Lautering Collaboration): Once conversion is complete, the mash is transferred, or the internal false bottom serves to separate the sweet liquid wort from the residual spent grains via a controlled vorlauf (recirculation) phase.

Standard Engineering Anatomy
Vessel Body: Dual-walled tank with a dome top and a flat/sloped bottom designed for complete fluid drainage.

Drive Assembly: Heavy-duty motor and gear reducer equipped with a Variable Frequency Drive (VFD) for precise speed regulation.

Milled False Bottom: Laser-cut, heavy-duty V-wire false bottom (0.7mm gap) provides maximum wort flow rates while preventing grain bed compaction.

Monitoring Hub: High-accuracy PT100 temperature sensors, sanitary glass manhole, and internal LED lighting.

Premium Optional Configurations
Automated PLC Touchscreen Integration: Full recipe management, automated multi-step mashing profiles, and pneumatic valve control.

Electronic Load Cells: High-precision weighing sensors integrated into the vessel legs for real-time grain and water weight monitoring.

Variable Speed Spent Grain Plows: Reverse-direction plows that automatically push spent grains out of the side manway.

Condensate Steam Stack: Top-mounted vapor condenser to eliminate interior moisture without external wall venting.

Every vessel undergoes a rigorous quality validation process before shipment to ensure international compliance and structural longevity:

Material Certification: Full traceability on all stainless steel plates with mill test reports.

Pressure & Leak Testing: All heating jackets are pressure tested up to 0.3 MPa to guarantee structural safety and seal integrity.

Passivation Treatment: Complete internal acid pickling and passivation to form a highly durable chromium oxide protective layer.

Weld Inspection: Dye penetrant testing on structural joints and visual inspection of all sanitary polishes.

To provide an accurate engineering quote and blueprint, our technical team customizes each Mash Tun based on your specific brewery requirements. Please consider the following factors when submitting your request:

Heating Source Availability: Specify if your facility utilizes low-pressure steam, direct gas firing, or electric power.

Brewhouse Configuration: Let us know if this vessel will function strictly as a Mash Tun, a combined Mash/Lauter Tun, or part of a 3/4/5-vessel brewhouse.

Space & Height Constraints: Provide ceiling heights and floor layout limitations so we can adjust the vessel diameter and leg heights accordingly.
