Efficiency and precision for an artisan product of excellence

What do you know about cheese aging and ripening? How many factors help cheese have a delicious taste and nuances in flavour? Should the climate be warm or cold, ventilated or not? All these questions arise when dealing with cheesemaking. In the past, cheese aging was managed with natural storage inside caves, and there was considerable waste due to incorrect temperature, too high humidity or a lack of ventilation. Now, cheesemaking has become significantly easier, as cheese can be aged in optimum conditions.

Today cheesemakers face the problem of how to age their cheese by seeking the best way to combine traditional methods with innovative technologies.

For more than 50 years, Guglielmi Stagionatura has stood out for the quality of the service it offers numerous leading Italian cheesemakers, in particular for hard cheeses. 

It now has a new solution available, thanks to the design and development work carried out by Merenti Refrigerazione, a local refrigeration company, and perfectly implemented in the Guglielmi Stagionatura facilities.

Guglielmi’s production site is located in the mountains in Valdastico, which helps prevent the cheese from being exposed to high temperatures and a lack of ventilation.

Yet the location is not the only important aspect for aging cheese: for higher quality and a perfect climate, something else is needed, which on one hand helps provide the best environmental conditions, and on the other reduces energy consumption.

The contractor thus decided to install a programmable controller and use a custom software application

What can a custom application bring to cheese aging? Certainly temperature and humidity management during cheese storage, with the maximum flexibility.

The solution adopted provided the optional combination of multiple factors: the system uses advanced features such as free cooling, in which a damper is activated to let in outside air whenever the weather conditions allow, thus reducing energy consumption. The electronic expansion valves ensure accurate cooling control, while the external compressor rack optimises floating condensation pressure and heat recovery, bringing an overall reduction in energy consumption of around 30%.

To ensure the highest efficiency, the system was equipped with a supervisory system, capable of monitoring up to 50 devices. Connected via RS485 serial lines, the system centralises the data from the 16 active devices in the system, and sends notifications via email or Telegram in the event of alarms. This solution not only makes maintenance much simpler and more timely, but is also used to log the temperature and humidity data

Furthermore, Guglielmi offers its customers the possibility to access a dedicated web site, where they can monitor the status of their wheels of cheese in real time while they are aging.

In 2023, Guglielmi opened a new processing plant for the production of artisan cheese. Here they make high-quality cheese, including blue cheese and other specialities. The storage rooms are managed by cold room controllers, designed to maximise flexibility and adapt to different processing needs. Each room is equipped with a humidity and temperature control module, as well as electronic valves for precise management of the refrigeration system. The new plant is also integrated connected to the supervisory system, ensuring continuous monitoring and perfect synchronisation with the existing operations.

Through this installation designed by Merenti Refrigerazione, Guglielmi was able to optimise the ripening process, ensuring stable environmental conditions, lower energy consumption, and higher quality of the end product.
