Continuously Operating Spiral System has always been corresponded with demand in which the products should be sprinkled with cold water and thus cooled faster. Finally, based on our proven COSS with circulating air cooling, we have realized a machine with water cooling. During the construction were not only the hygienic requirements taken into account. Only corrosion-free materials were also used. The drive technology is located outside the enclosure and the sensors are equipped with the highest possible protection.
The double towered COSS stands in a 4 m³ collecting tank. From this reservoir the cooling water is sucked in with a pump, filtered and cooled by a plate heat exchanger. A float switch provides the right amount of water. Via the internal piping the volume flow is evenly distributed in the system over approximated 350 nozzles. During the run the hot products are sprayed with cold water through the nozzles arranged parallel to the chain course.
The enclosure of the machine ensures that no splash water or spray mist penetrates to the outside. It is designed by the combination of VA-sheet and macrolon in such a way that you can look well into the inside of the cooler from the outside.
The number and arrangement of the individual door segments is chosen in such a way that a intervention on all sides of the system is without any tool possible.
After the wet cooling process the product is dried on the system mat chain by an Airknife. The residual water runs back into circulation.
