Modular Tunnel Pasteuriser/Cooler
The Pasteuriser/Cooler machine pasteurises and cools food products in metallic, glass, plastic or multi-layer containers under atmospheric pressure.
The machine is composed of modules that can operate as pasteurisation or cooling, depending on the predefined programme.
The containers are introduced into the pasteuriser-cooler through a single or multi-lane conveyor belt where they can be preheated, if necessary, or pasteurised.
Pasteurisation is done by heating the product contained in the cans or jars, through hot water that comes out from exchangers. The latter expels hot water that is sprayed onto the containers through nozzles fed by one or more pumps.
The water temperature is measured by probes that permit the opening of the valve or valves so as to maintain the set temperatures in various points.
The jar cooling is made by cold water spraying, or, depending on the need, with water at decreasing temperatures, supplied by centrifugal pumps.
All the pasteurising and cooling temperatures applied are recorded during the product’s thermal treatment.
The excess of water in the containers that come out from the pasteuriser is dried thanks to an air blade. After that, through a multi-lane conveyor belt, they are led to the subsequent processing phase.
