Frequently Asked Questions

What maintenance is required on a Stout Tanks mill?

Regular inspection, cleaning and replacement of wear items like belts, fasteners and rollers is needed. Monthly verification of roller gap and tension is recommended along with checking motor amp loading during operation for any issues.

What safety precautions should be used with these mills?

• Use dust collection system and wear respiratory protection
• Ensure guards are in place during operation
• Post safety procedures and provide staff training
• Install emergency stop buttons within easy access
• Verify electrical wiring properly grounded

What determines the roller gap setting?

It depends on the malt variety, with harder grains requiring a wider gap generally between 0.035 to 0.075 inches. Softer malts can use a tighter gap down to 0.015 inches. Sieve analysis of the grist is needed to confirm optimum extraction efficiency is achieved.

How much capacity is needed for a brewery?

Base the malt mill size on batch volumes required, number of turns per day, and allow 20-30% extra capacity. A typical 10 barrel brewhouse would need around 1500 lb per hour mill capacity for example. Scale the hopper, motor HP and automation features accordingly.

What options help automate the malt milling process?

Popular accessories are integrated hopper scales for batch recipes, motorized hopper dumps to feed the mill automatically, and electronic variable frequency drives for the roller speed. Gravity roller mills allow staging multiple mills in a vertical layout to save space.

Can other grains besides barley malt be crushed in a Stout Tanks mill?

Yes, these mills can crush alternative grains like wheat, rye, oats, corn and rice effectively as long as the proper hardness roller gap is set based on the grain texture and husk characteristics.

Conclusion

With heavy duty stainless steel construction and extreme reliability, Stout Tanks malt mills are a smart investment for commercial scale brewing systems requiring efficient grain crush for mashing. Their modular platform offers unparalleled customization to specification along with top-notch American manufacturing and customer support. While requiring safety precautions and regular maintenance, these mills drive quality and consistency in beer production – making your equipment purchase decision an easy one if brewing world-class craft beer is the goal.

Additional FAQs for Stout Tanks Malt Mill

1) What crush targets should I use with a Stout Tanks Malt Mill for best lautering and efficiency?

• Aim for 65–75% husk retention, 15–25% coarse grits, 5–10% flour by sieve. A typical roller gap starts around 0.035–0.045 in (0.9–1.1 mm) for standard 2-row barley; adjust by malt friability and lauter performance.

2) How do I calibrate and verify roller gap accuracy?

• Use precision feeler gauges across both roller ends with the lockouts engaged, then verify with a sieve test (ASBC Malt-4/Grain-4). Re-check after thermal cycles or bearing service. Log settings by malt lot to improve repeatability.

3) Can a Stout Tanks Malt Mill support wet conditioning (malt misting) to reduce dust and shattering?

• Yes, provided you use corrosion-appropriate materials and clean after use. Lightly mist malt to ~1–2% additional moisture, rest 10–20 minutes, then mill. Expect improved husk integrity and lower dust load. Confirm with your supplier re: warranty/cleaning requirements.

4) What motor control setup is recommended for consistency and safety?

• A VFD with soft start, overload protection, and E‑stop integration. Program an amperage alarm band to detect stones/bridging. For 3–5 HP systems, confirm proper breaker sizing, grounding, and lockout/tagout per NFPA 70.

5) How do I integrate dust collection and explosion prevention around the mill?

• Use local extraction at the hopper and discharge, conductive hoses, proper bonding/grounding, and Class II Div 2–appropriate components if required. Keep housekeeping strict. For high-risk environments, consult NFPA 61/652 and local AHJ.

2025 Industry Trends: Stout Tanks Malt Mill

• Data-driven milling: More brewhouses pair mills with inline scales and batch logging to correlate crush metrics with brewhouse efficiency.
• Safer mill rooms: Increased adoption of dust collection upgrades, bonded hoses, and interlocked guards to meet insurer/AHJ expectations.
• Wet conditioning on the rise: Small and mid-size breweries use misting to boost lauter speed on adjunct-heavy grists while reducing dust.
• Sustainability focus: Lower horsepower draw via optimized VFD profiles and preventative maintenance of bearings/rollers to cut energy use.
• Supply chain stability: Stainless pricing and lead times have normalized versus 2022–2023, with modest YoY price changes.
