Tunnel
pasteurizer heats the containers by means of water jets,
while they pass below on a conveyor belt. The heating
or cooling of any beverage product is determined by
the convective heat flow setup by changes in temperature.
The fluid layer next to the container wall will rise
when the temperature increases and vice versa when the
temperature falls. Taking account of the type and size
of container, the material it is made of -- whether
it be glass, PET aluminum or steel – the wall
thickness and the thermal properties of the beverage,
it can be seen that the pasteurizing conditions must
be set for each individual circumstance.
A
tunnel pasteurizer has advantages, in that it is known
that the product sealed within the container has been
pasteurized. |
