As the demand for cost-effective, long-life fermentation vessels increases, FRP fermentation tanks have become a preferred alternative to traditional stainless steel and carbon steel tanks, especially where chemical or pH exposure is a concern.

Características clave

• Chemical & Corrosion Resistance: Excellent resistance to organic acids, bases, solvents, and disinfectants used in cleaning (CIP/SIP systems).

• Estabilidad térmica: Maintains mechanical integrity under fermentation temperatures up to 120°C depending on resin system.

• Sanitary Inner Surface: Smooth, non-porous, food-safe inner liner prevents contamination, easy to clean and sterilize.

• Customizable Configurations: Built in vertical or horizontal form, with options for conical bottoms, heating/cooling jackets, agitators, and nozzles.

• Ligero y de alta resistencia: Easy transportation and installation, especially for large-scale tanks.

• Económico: Lower lifecycle cost compared to metal fermentation tanks due to corrosion resistance and minimal maintenance.

Aplicaciones

FRP fermentation tanks are suitable for aerobic and anaerobic fermentation processes in:

• Pharmaceutical Industry: Antibiotics, insulin, enzymes, and probiotics.

• Food & Beverage Industry: Yogurt, kombucha, vinegar, beer, wine, soy sauce, pickles, and kimchi.

• Agricultura: Animal feed fermentation, silage, and biofertilizer production.

• Biotechnology: Bioethanol, biogas, bioplastics, algae, and microbial biomass production.

• Tratamiento de aguas residuales: Anaerobic digestion for methane production.

• Distilleries: Alcohol and spirit fermentation using molasses, grains, or fruits.

Construction & Materials

FRP fermentation tanks are fabricated through either bobinado de filamento, bandeja manual, o infusión al vacío, using corrosion-resistant thermosetting resins and high-strength fiberglass.

1. Inner Liner (Corrosion Barrier)

2. Structural Layer

• Reinforced with fieltro de vidrio, woven roving, o filament-wound continuous fibers.

• Optimized laminate schedule for hoop and axial strength, especially for tall vertical tanks.

3. External Finish

• Gelcoat Layer: UV-resistant coating for outdoor exposure.

• Opciones de color: Grey, white, green, blue, or custom colors.

• Aislamiento térmico: Optional PU foam or rockwool jacketing for temperature-sensitive fermentation.

Design Configurations

Sanitation & Sterility

• Smooth inner surface with resin-rich liner prevents microbial buildup.

• CIP/SIP Ready: Compatible with steam-in-place and clean-in-place systems.

• Antimicrobial liners optional for high-purity applications.

Thermal Performance

• Operating temperature range: -40°C to 120°C (resin-dependent)

• Insulated versions maintain fermentation temperatures with minimal energy loss.

• Optional thermal jackets (glycol or steam) support temperature control.

Advantages of FRP Over Stainless Steel Tanks

Instrucciones de instalación

1. Base: Concrete slab or steel platform with level surface

2. Hoisting: Use built-in lifting lugs or straps; avoid side pressure

3. Anchoring: For outdoor or seismic zones, anchor to resist uplift

4. Conexiones: Flexible couplings recommended to allow for thermal expansion

5. Pruebas: Hydrostatic leak testing prior to commissioning

Consejos de mantenimiento

• Inspect tank internals annually for wear or damage

• Sanitize before and after each fermentation cycle

• Use non-abrasive CIP solutions

• Check gaskets, seals, and nozzles for cracks or buildup

Optional Upgrades

• Stainless steel or HDPE nozzles

• Anti-foam spray rings

• External viewing windows

• Agitator with VFD controller

• PLC control system for real-time fermentation monitoring

• Flame arrestors for alcohol fermentation
