PASTEURISATION
STERILISATION
The main different phases in a sterilization (or pasteurization) cycle
Heating phase or Come-up Time (CUT):
Steam inlet, in the primary circuit of heat exchanger is heating the process water till programmed value.
Holding phase :
Temperature and pressure are stabilized
Cooling phase :
Cold water is injected in the heat exchanger in order to cool down the process water. Water flow is monitored through an automatic on/off control valve linked to the MPI. The cooling water is not in contact with the products and as such can be used again (in a cooling tower for example)

Main advantages of STERIFLOW process
FOOD SAFETY
Same treatment of all the products whatever theirposition or their packing type.
No possibility of re-contamination as coling is made with steril water.
PERFORMANCE
The programmed cycle can be exactly reproduced
Temperature and pressure ( con,ter pressure) are really independant.
Great accuracy of tmperature and pressure, thanks to the MPI Contrller, for all products and packing (double trays, trimple compartments, easy opening, ...)
MAINTENANCE
Very low maintenance costs. The heat exchanger is a platular with welded plates ( almost nomaintenance). All parts are static , except the pump ( low pressure pump).
ENERGY SAVINGS
ENERGY and UTILITIES
Energy : steam consumption
Concerning consumption of energy and more specially of steam,
the subject needs really a serious and honest examination.

The calories used to heat the cascading water are compensated by the calories
gained in the recuperation of condensates,
one of the great advantages of the cascading water process.

Utilities : operating costs
To compare all the processes, the most interesting is to calculate the
cost per ton of products of our main sterilization processes :
STERIFLOW, STERISTEAM and STERISPRAY.
This calculation has been made from a standard 5 Baskets retort,
filled with 4200 cans 1/2 ( 420 g ) of vegetable.
(same capacity for all the processes)
OUR ENGINEERS CAN EXPLAIN YOU ALL THESE CALCULATIONS.
TO COMPARE THE PROCESSES IT'S VERY IMPORTANT TO TAKE INTO
ACOUNT ALL THE COSTS INVOLVED.
CONCLUSION : cost per ton of product
STERIFLOW 11.7 €/T ...........AIR/STEAM 13.1 €/T ........... SPRAY 15,5 €/T
