Spiral Pasteurizer/Cooler


The Spiral Pasteurizer/Cooler is suitable to pasteurize and cool rectangular containers or pouches.

Its external aspect is of a net, composed of a conveyor belt that develops vertically, forming a spiral.
It is made up of two units, the first used for pasteurization and the second for cooling.
The pasteurization is made by heating the containers with hot water sprays, obtained through water-steam heat exchangers and sprayed onto the containers by nozzles, fed by one or more pumps.
The water temperature is measured by probes that allow to control the opening of one or more valves so as to maintain the temperature set in the various areas.
The container cooling is done by cold water spraying or, if necessary, by water at descreasing temperatures, fed by centrifugal pumps.
All the pasteurization and cooling temperatures applied, are recorded during the product’s thermal treatment.
The containers coming from the pasteurizer are dried from excess water by means of an air blade and transferred to a multi-lane conveyor belt, then sent to the successive working phase.
