Humidity control for cheese processing facilities is crucial for ensuring optimal conditions during the coagulation process, which involves acidification with bacterial cultures and the subsequent addition of enzymes to thicken the liquid obtained from cows, goats, sheep, and other mammals.
Cheese needs to be refrigerated to retain its freshness. However, lowering temperature causes condensation, which in turn leads to the growth of mould.
A typical dairy, cheese, and powder processing unit grapple with the following humidity-related challenges:
- Wet Surfaces in the cheese processing areas due to condensation
- A risk for mould growth and bacteria developing in critical locations due to wet surfaces and high humidity
- Unpredictable curing time and quality deterioration due to external moisture conditions
- Variable productivity and wasting of product because of the layer of fungus and mould after the curing time
- Risk of moisture regain during cooling stage of Cheese powder before packaging
Maintaining humidity at a proper level in the Cheese Cure Room has some beneficial effects. However, new food safety and standards regulators call for all areas that have food process must be free from ceiling condensation.
Importance of Humidity Control for Cheese
- Product Quality: Maintaining specific humidity levels is critical for achieving consistent quality in cheese production. Controlling humidity helps prevent moisture-related issues such as uneven drying, mold growth, and texture variations, ensuring that the final product during the cheese packaging process meets desired standards.
- Preservation: Proper humidity control helps preserve the integrity and shelf life of cheese by minimizing the risk of spoilage. Excessive moisture can accelerate microbial growth and lead to deterioration, while inadequate humidity levels can cause the cheese to dry out and lose flavour.
- Process Efficiency: Humidity control optimizes the cheese-making process by providing a stable environment for coagulation, fermentation, and curing. This helps streamline production operations, reduce processing time, and improve overall efficiency.
- Regulatory Compliance: Cheese production facilities are often subject to stringent regulations regarding food safety and hygiene. Maintaining appropriate humidity levels contributes to compliance with industry standards and regulatory requirements, ensuring the safety and quality of the end product.
Humidity control for cheese plays a crucial role in ensuring the success of cheese processing operations, from raw milk coagulation to the aging and packaging stages, ultimately impacting product consistency, safety, and marketability.
Conventional Method Used
In many traditional Cheese processing facilities, drying is based on heating and ventilation. Such a drying process leads to unpredictable product quality due to outdoor climate and seasonal variations.
Traditional HVAC system that keeps the RH around 90% / 22°C +-2 (72 + -28) because of the moisture from the product itself.
Traditional cheese processing facilities often rely on rudimentary drying methods such as heating and ventilation, which are susceptible to fluctuations in outdoor climate and seasonal changes. This approach results into inconsistent product quality, as the ambient conditions play a significant role in the drying process.
General Recommendation
Maintaining ambient relative humidity levels between 45% and 55% is recommended for optimal performance and reliability at room temperature maintained between 20 °C to 22 °C (68°F to 72°F). Systems that ensure effective humidity control for cheese can play a crucial role in maintaining the desired form and quality of cheese.
Bry-Air Solution
Bry-Air Desiccant Dehumidifiers remove moisture from the air in the processing, storage and packaging areas to help improve the quality and prevent spoilage. Humidity control is the optimal alternative solution for the handmade type of high quality Cheese production. Using Bry-Air Desiccant Dehumidifier, the producer can have full control of the curing time and quality of Cheese avoiding the mould formation in the Cheese processing facilities. Inlet air dehumidification in spray drying and fluidised bed drying prevents seasonal variation in production capacity.
Inlet air dehumidification in spray drying and fluidised bed drying not only enhances production consistency but also minimizes the impact of seasonal fluctuations on capacity, ensuring reliable output year-round. Additionally, by incorporating Bry-Air Desiccant Dehumidifiers, cheese producers can exert precise control over curing time and product quality, mitigating the risk of mould formation and spoilage in processing facilities, thus ensuring the integrity of their cheese products.
Advantages of Bry-Air Dehumidifier in a Cheese Processing Facility
- Drying at lower humidity levels ensures consistent and superior quality of cheese products
- Helps reduce curing time by up to 70%
- Eliminates the need for mechanical removal of the mould layer before packing
- Helps retain original quality, flavour, and taste of cheese
- Condensation prevention, thereby eliminating contamination, fungal growth and wet surfaces
- Improved productivity as production schedule independent of the prevailing weather conditions
- Improved hygiene and sanitary conditions resulting in waste reduction
- Ease of installation and can be placed anywhere
Maintaining lower humidity levels in cheese production not only ensures superior product quality but also offers various operational benefits. By reducing curing time and eliminating the need for mechanical removal of mould layers, businesses can streamline their processes and improve productivity. Moreover, the preservation of original flavour and taste, along with the prevention of condensation, enhances product integrity and minimizes the risk of contamination. The flexibility of installation further adds to the convenience of implementing humidity control systems, promoting improved hygiene and sanitary conditions. Overall, the adoption of such measures not only reduces waste but also contributes to a more efficient and reliable cheese production process.
