How to prevent and manage grey mold in the food industry
Grey mold (Botrytis cinerea) is one of the most common and costly forms of fungal contamination in food production and storage environments. It thrives in humid conditions and poses a serious risk to food safety, shelf life, and regulatory compliance.
At Fisair, we help you eliminate this threat through targeted air dehumidification solutions, designed to keep humidity under control throughout your facility.
Why is humidity control important?
Excess moisture in the air creates the perfect environment for grey mold to grow, especially in:
- Cold storage rooms
- Packing areas
- Cheese aging and fermentation chambers
- Bakeries and drying tunnels
The key to prevention? Keeping relative humidity below the threshold at which mold spores activate—typically under 70%, or even lower in sensitive environments.
Our recommended solutions
To effectively control humidity and stop grey mold before it appears, we recommend these three powerful industrial dehumidifiers:
DFRA industrial dehumidifiers
Designed for continuous, high-efficiency operation in industrial environments. Ideal for food processing and storage areas requiring stable humidity levels year-round.
DFLEX modular dehumidifiers
Flexible, customizable units tailored to each process’s specific needs. Perfect for facilities with variable moisture loads or zones requiring independent humidity control.
DFRIGO dehumidifiers for cold storage
Specifically designed for cold rooms and refrigerated environments. Maintain low humidity levels even at reduced temperatures, preventing mold growth in cold storage conditions.
Applications in the food industry
- Cold storage for meat, fish, and fresh produce
- Bakery production and packaging lines
- Cheese aging and curing rooms
- Storage areas for dry foods and ingredients
Real-world impact: bakery mold elimination
A major food producer was experiencing recurring mold contamination on packaged baked goods. After installing a DFRA dehumidifier in the cooling and packaging zone, humidity dropped by 20%, and mold incidents were virtually eliminated within weeks — reducing product losses and ensuring hygiene compliance.
