It is usually placed after the pasteurizer to dry the product with hot air, with a customizable percentage of humidity. Constituted of a single treatment belt that feeds the product while the two ventilation systems dry it superficially.
Once the product exits the pasteurizer it is humid on the surface and the Drying Zone allows to dry it and prevent that products stick to one another.
Internal structure of the machine with circular section to avoid product stagnation and ease the washing process.
Two ventilation systems place below and under the belt, made ofbattery with steam smooth tubes and ventilators controlled by inverter.
Extracting system for humid air through a ventilator controlled via PLC.
In order ease the washing process, the machine features a stainless-steel structure and rinsing ramps to reduce machine washing time.
The bottom panel is inclined on the sides to drain washing water. Openable lateral panels hinged for accessibility. Thanks to peripheraleaves washing water can be collected in different points.
Machine performance
- Usable belt width: 750 - 1500 – 2000 mm;
- Drying chamber length: 3-6 m.

The upper ventilation system is composed ofbattery functioning with steam and ventilators controlled by inverter for the heating of the water used during the treatment.
The bottom ventilation system is made of battery functioning with freon/glycolyzed water and ventilators controlled by inverter to monitor humidity in the air.
In order ease the washing process, the machine features a stainless-steel structure and rinsing ramps to reduce machine washing time. The bottom panel is inclined on the sides to drain washing water. Openable lateral panels hinged for accessibility. Thanks to peripheraleaves washing water can be collected in different points.
Differing from the standard version, the HE features a ventilating system equipped with a condensation system to monitor more accurately air humidity. This allows to have a greater control on the quality of the finished product.

The breakthrough that changed spray drying
In 1976, NIRO engineers responded to a competitive challenge by rethinking what spray drying could do. Their idea became the multi-stage dryer MSD. Fifty years later, the same fundamental principle helps turn liquids into the powders used in essential nutrition products and important medicines around the world. Refined through decades of engineering expertise, customer insight and continuous development, MSD is a story of innovation with lasting impact.
Beyond the machine: unlocking better plant performance
An efficient machine does not automatically make an efficient factory. Real improvement often starts by looking beyond individual equipment and understanding how processes, energy systems and operating decisions affect one another. It’s a holistic approach designed to uncover opportunities that might otherwise be missed.
How a valve reshapes the way food and drinks are made
In food and beverage plants, valves are commonly operated using compressed air. GEA Hydract® Actuation Technology moves valves with water instead, in a closed, digitally controlled circuit. The result is a valve that can be held exactly in place and steered in fine-tuned steps. This results in lower energy use and greater control.
