Beer Fermentation Tank

 

 

 

• Beer & Wine: Fermentation tanks create the optimal temperature and environment to drive yeast activity, converting sugars into alcohol and key flavor compounds.
• Dairy: Stainless steel tanks are essential for yogurt and cheese production, enabling controlled lactic acid fermentation to enhance taste and nutrition.
• Fermented Condiments: For vinegar, soy sauce, and similar products, stainless steel tanks ensure stable pH and temperature control-critical for consistent flavor and shelf life.

 

 

Capacity (Volume):

Working Volume: 1,000–100,000 L (or more for industrial breweries)

Total Volume: ~10–20% larger than working volume (to allow for foam/yeast headspace)

Material: Stainless steel (AISI 304 / 316L)

Design Type:

Cylindro-Conical Fermenter (CCV) – Standard for yeast settling

Unitank – Multi-purpose (fermentation + conditioning)

Open Fermenter – Traditional (e.g., for some ales)

Structural Parameters

Diameter-to-Height Ratio: ~1:2 to 1:3 (optimized for yeast sedimentation)

Cone Angle: 60°–70° (for efficient yeast discharge)

Wall Thickness: 2–5 mm (depending on pressure requirements)

Insulation: Polyurethane foam (50–100 mm) for temperature stability

Temperature Control

Cooling Method: Glycol jacketing (single/double jacket)

Cooling Surface Area: ~0.3–0.5 m² per 1 hL capacity

Temperature Range: 0–30°C (adjustable for ale/lager fermentation)

 

Pressure & Gas Handling

Maximum Working Pressure: 1.5–3 bar (for pressurized fermentation)

Pressure Relief Valve (PRV): Typically set at 1.5–2 bar

Carbonation Capability: Yes (if pressure-rated)

CO₂ Harvesting: Possible in closed fermenters

Sanitation & Accessories

CIP (Clean-in-Place) System: Spray ball(s) for automated cleaning

Sample Valve: For gravity/pH monitoring

Yeast Dump Port: At the cone bottom

Manhole: For manual inspection (DN500 or larger)

Additional Features

Monitoring & Control:

Temperature probes

Pressure sensors

Digital control (PLC/automation)

 

Accessories:

Sight glass

Dry hopping port

Carbonation stone (optional)

 

 

 

 

Efficient Yeast Management

Natural Sedimentation: The cone-shaped bottom allows yeast and trub (sediment) to settle by gravity, reducing manual removal.

Easy Yeast Harvesting: Brewers can collect and reuse healthy yeast from the cone for future batches (cost-saving).

Reduced Beer Loss: Clear separation of beer from yeast/trub improves yield.

 

Improved Fermentation Control

Temperature Stability: The tall, narrow design promotes natural convection, ensuring even cooling (via glycol jackets).

Pressure Fermentation: CCVs can be sealed for pressurized fermentation (useful for lagers and carbonation).

 

Sanitation & Cleaning (CIP)

Smooth Interior: No corners or hard-to-reach areas → easier Clean-in-Place (CIP).

Hygienic Design: Stainless steel construction prevents contamination.

 

Versatility

Multi-Stage Fermentation: Can be used for primary fermentation, conditioning, and even lagering in one vessel (if designed as a Unitank).

Suitable for Various Styles: Ideal for ales, lagers, and high-gravity beers.

Scalability

Used in small craft breweries (1,000 L) to industrial facilities (500,000+ L).

 

 CO₂ & Pressure Management

CO₂ Collection: The sealed design allows CO₂ capture for carbonation or reuse.

Pressure Relief Valves (PRVs): Prevent over-pressurization during vigorous fermentation
