K40 3V Brewing System – 46L Three-Vessel Stainless Brewhouse

46L Three-Vessel Brewing System.

Dedicated HLT. Dedicated Mash. Dedicated Boil. 7kW total heating. Full stainless tri-clamp architecture.

Designed operating range

• Nominal vessel capacity: 46 L (each vessel)
• Recommended production range (into fermenter): 25–40 L
• Maximum practical knockout volume: 42–44 L
• Flexible batch capability: ~20–40 L

Optimized for consistent operation in the 25–40L range.
Smaller batches are fully supported by adjusting heating power and flow control.

System architecture

• HLT (Hot Liquor Tank): dedicated heating vessel
• Mash Tun: laser-cut stainless false bottom (K40 size)
• Boil Kettle: electric heating configuration
• Routing: full 1.5" sanitary tri-clamp manifold

No shared vessel compromises. Each stage runs independently.

Heating performance

• 2 × 3.5 kW tri-clamp heating elements
• Total installed power: 7.0 kW
• 2 × Inkbird C236T (16A EU plug)

Electrical requirement: two independent 16A circuits.

Estimated heat-up (35 L water, 15°C → 100°C):
≈ 20–30 minutes depending on ambient conditions.

Boil performance (30–40 L):
Stable rolling boil. Expected evaporation ~6–8% per hour.

Grain load & mash performance

• Recommended grain bill: 8–14 kg
• High gravity capability: up to ~16 kg
• Recommended mash thickness: 2.6–3.2 L/kg

Example: 12 kg grain × 2.8 L/kg → ~34 L mash volume.
Stable recirculation within this range.

For optimal flow stability, mash thickness below 2.3 L/kg is not recommended.

Hydraulics & flow

• 2 × magnetic pumps (R15)
• Stainless manifold routing
• 1.5" tri-clamp quick-connect fittings
• Integrated sanitary 4-way cross

Dual-pump routing supports:

• HLT → Mash transfer
• Mash recirculation
• Sparge routing
• Whirlpool & knockout preparation
• CIP recirculation (with optional spray head)

Cooling performance

• Counterflow wort chiller (single-pass)
• Optimized for 25–40 L knockout volumes

With 10–15°C groundwater:
Single-pass cooling to 18–22°C achievable at controlled flow rate.

Estimated knockout time (35 L): 6–12 minutes depending on water pressure and delta-T.

Oxygenation & monitoring

• Integrated 1.5" sanitary 4-way cross
• 1.5" small carb stone (oxygenation)
• Thermowells included for temperature monitoring

Inline oxygenation and sanitary temperature control supported via tri-clamp architecture.

Power & installation requirements

• 2 × independent 16A circuits
• Stable water supply
• Load-bearing surface (filled system approx. 120–160 kg total)

Ensure proper electrical preparation and structural support.
