The RF is composed of a conveying belt which brings product inside a water tank that contains cool water with fixed temperature.
From a structural perspective, the conveying belt is made with plastic material and it features upturned sides to contain the product, while the top panel is in stainless steel. The insulated tanks containing water is inclined in one point to allow water draining.
The cooling system utilizes water that is cooled thanks to an external heat exchanger glycolyzed water/water, which is controlled through a modulating valve managed via PLC. The cooling water is recycled through a pump that distributes it on the whole surface with a system of adjustable sprays, guaranteeing a uniform cooling of the product. The cooling water level is maintained via PLC.
In order to regulate product cooling, it is possible to adjust: cooling time, water temperature, remixing by increasing or decreasing it.
The opening of the cooler happens through an automatic multilayer system which allows to distance the belt from the panel, giving high accessibility for washing. Moreover, the machine is in stainless steel, to ease the washing process and it features a rinsing ramp for the belt to reduce washing time. The entire structure is designed to avoid any product stagnation.
Machine performance:
- Belt usable width: 1000-1200 mm;
- Cooling length: 3-6 m.

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.
