Physis dryers are designed to be more energy efficient as they use advanced technologies such as the use of an adjustable flow of hot air within the modules that can significantly reduce energy consumption compared to traditional methods.Since drying takes place at lower temperatures and in a more uniform manner thanks to the work of the augers and the hot air inside them, it is possible to maintain the colour and consistency of the dried materials better than rotary drum drying, which could generate excessive heat and, more importantly, alter the characteristics of the final product by producing the so-called caramelisation effect (especially for sludge of an agricultural nature such as olive pomace). In the context of a drying process, the aim is to remove moisture from a material without necessarily causing caramelisation of the sugars present. Physis dryers are suitable for a variety of different materials, thanks to their ability to precisely regulate the temperature and power of the hot air flow. This makes them suitable for a wider range of applications than rotary drum dryers. Physis dryers are often more compact and take up less space than rotary drum dryers, providing a significant advantage in environments where space is limited. Physis dryers are equipped with advanced control systems that allow the drying process to be precisely monitored and regulated. This level of control can improve the consistency and quality of the process.
