METHOD AND PLANT FOR PASTEURIZING AN EGG-CONTAINING FOOD PRODUCT

摘要

A plant for pasteurizing an egg-containing food product comprises a heating section (3) for heating the product to a first operating temperature (T1) above 5O0C1 an overheating station (4) for overheating the product to a second operating temperature (T2) higher than the first operating temperature (T1), oscillating means (18) for generating a radio-frequency electromagnetic field in the overheating station (4), at least one conduit (6) having an inlet (2) and an outlet (5) and at least a connecting portion (16) for connecting together said heating section (3) and said overheating station (4), at least one first thermal holding station (15) in said intermediate portion (16), means (8) for circulating the product in said conduit (6). The circulating means (8) are adapted to circulate the product in said overheating station (4) at a second operating speed (V2) in a substantially turbulent regime for a maximum operating time (t2) of 0.1 s to 5 s, for the second operating temperature (T2) to fall in a range from 55°C to 75°C.
