Spiral cooler - thermal treatment
Machine designed to cool the product and take it to the desired packaging temperature.
The Spiral Cooler features conveying belts that transport the product while a ventilation system cools it down, thanks to the internal structure characterized by the spiral, with circular sections to prevent product stagnation and ease the washing process.
The spiral belt allows to cool the product and take it up to facilitate the packaging process.
The ventilation system is made of a battery functioning with freon/glycolyzed water and ventilators controlled by inverter for air cooling (the 6-meter version has 2 ventilation systems).
In order to ease the washing process, the machine features a stainless-steel structure and rinsing ramps to reduce machine washing time. Openable lateral panels hinged for accessibility. The entire structure is designed to guarantee high accessibility and facilitate the washing operations, avoiding product stagnation.
The air flows are optimized to guarantee equal temperature in the whole spiral length.
It is possible to use belts with reduced curve in order to decrease the spiral footprint.
