Installing and Operating Stout Tanks Malt Mills

Proper installation and operation ensures optimum performance and safety:

Table: Stout Tanks Malt Mill Installation & Operation

LocationIndoor, dust free, non-slip flooring, adequate ventilation, access to power supply
SetupLevel unit, anchor hopper and adjust roller gap
SafetyEnsure guards installed, post safety procedures, use dust collection
OperationWear PPE, feed hopper evenly, monitor amperage load, adjust gap as needed
MaintenanceInspect and replace wear items regularly (belts, bearings, rollers), keep unit clean
Efficiency CheckVerify grain crush size post-milling via sieving

Ideally locate the malt mill in an enclosed mill room with dust collection running during operation. Make sure staff are properly trained on standard operating procedures. Perform regular maintenance and inspections to maximize efficiency and equipment lifespan. Adjust the roller gap based on malt variety to optimize extraction efficiency.

Choosing a Stout Tanks Malt Mill

Consider the following when selecting a Stout Tanks grain mill:

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.


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.
