The pasteurizer with overrushing has the simple but also very good effect that pasteurizing and cooling are used instead of the normally used hollow cone spraying nozzles, so called rinser plates which catch the water up to a certain height and then dispense through the holes in the lower floor area.
The principle is similar to that of a rainwater shower. Small threads of water go down over the containers from top to bottom and ensure that the product is evenly pasteurized with hot and cold water.
Another advantage of this system is that when dirt / contamination is in the water, the rinsing sheets can easily be cleaned from outside and removed if necessary.
There is no dead space concerning water/ transfer hot / cold. The small disadvantage of this is that it is very expensive to construct and is according to more expensive than conventional nozzles
Construction
The canisters are fed to the pasteurizer via the inlet conveyor in the pushing-in process. In the pre-treatment zone, water is sprayed out of the "hot cooling zone I" in the circulation process. The pasteurizing zone and cooling zone are each operated with tubs with holes for overflowing with hot and then cold water.
At the inlet and outlet transfer combs are placed to transfer the package to the main conveyor belt (plastic module belt). The pre spraying zone is fed with water from the warmest cooling zone.
In the pasteurizing zone a so called foot bath is possible. By lowering the module chain in this zone as well as variably adjustable water level.
