The role of temperature and humidity monitoring in cheese making

The cheese making process requires bacterial culture and the use of enzymes and stabilizers. This is a multi-step process. Cheese is stored in a cool, dry place and requires controlled temperature and humidity. Enzymes induce changes in the proteins and fats of cheese to impart flavor, aroma, texture, etc. features. Cheese ages for months to years in different climates as it determines the rate of ripening, weight loss, rind formation, surface microbiota development and appearance, taste and texture. Loss of water from the surface of hard cheese can cause cracks to form in the cheese.

I. Humidity VScontrol :

Precise moisture control is important not only to achieve the desired taste, texture and appearance characteristics, but also to minimize energy costs and maximize profits. If the cheese is excessively dry, energy consumption increases and production decreases, profits will be reduced.

① Cheddar cheese:temperature 4-8°C, RH%

② Emmental:temperature 8-12°C, relative humidity 85-90%, mature for 3-4 weeks, then increase the temperature to 22-25°C for 6-7 weeks, maintain the same level of humidity, then leave drop the temperature to 8-12°C for a few more months.

③ Brie and Camembert: temperature 12-15°C, RH% 90-94%, maturation time 9-30.

④Sky blue cheese:temperature 8-12°C, RH% 85-95%, ripening time from weeks to months.

Historically, cellars were used as ideal environments for cheese aging and storage, and are still in use today, but most storage areas are now man-made structures that use sensors for climate control, including including well-ventilated shelves, humidifiers andtemperature and humidity sensors and control systems.

The Food Aging (Cheese) Shelf utilizes a stackable polypropylene mesh that can be used for aging, curing and drying cheese for optimal ventilation and product support. Steam or adiabatic humidifiers can be used, the latter use a variety of techniques to introduce water into the air, causing relative humidity (RH) levels to increase and air temperature to decrease (dry bulb) by dispersing water droplets or allowing water to evaporate from a moist environment. This ultimately saves energy and costs.

The air in the room is often refreshed with outside air. Usually, the warmer air becomes saturated and causes condensation because the cooler air in the room holds less moisture than the incoming air. To prevent this, the relative humidity in the room should be measured and the incoming air should be controlled and dehumidified. Note that dehumidifiers usually include built-in humidity sensors.

High humidity and potentially condensed environments are difficult measurement tasks in the presence of ammonia, which will interact with humidity sensors and can cause sensor drift. Water must flow in and out of the sensor, which means that other gases can also block the active surface.


5. Hhumidity Mmeasure Ssolutions

Humidity sensors can struggle with violently high humidity, and even the best capacitive sensors can only achieve an accuracy of about +/- 2.0% above 90% relative humidity. If you’re concerned about accuracy and find your readings are drifting or you need to change sensors frequently, it might be time to consider using resistive sensors.

take the wall temperature and humidity sensor HT802C as an example, the operating temperature and humidity of the sensor circuit are -20℃~80℃ and 0%RH~100%RH respectively. The working temperature and humidity of the probe are -40℃~+125℃ and 0%RH-100%RH, respectively, which can meet the measurement needs of high humidity environment.
