Abstract:
Plant for the treatment of food products, which includes bringing the product into contact with ozone within an initial solution which contains, apart from the product, ozonized water, the plant comprising:a) at least two containers of initial solution, each container being associated with a set value of the dissolved-ozone content in the initial solution in question;b) a source of a treatment gas mixture which contains ozone;c) a primary source of water;d) means for ozonizing a stream of water coming from said primary source of water with the treatment gas mixture, which means are capable of producing, as their output, a liquid stream of ozonized water;e) means for injecting the liquid stream of ozonized water into each of said initial solution containers;wherein the injection means comprise at least two flow-control devices for controlling each flow of ozonized water injected into each of said initial solution containers;wherein said means for ozonizing a stream of water are capable of providing said liquid stream of ozonized water having a dissolved-ozone content that is greater than or equal to the highest of said set values of ozone content which are associated with said initial solution containers;wherein the plant comprises means for analyzing the dissolved-ozone content in each of said initial solution containers as well as data acquisition and processing means capable of receiving the result of the analysis of the dissolved-ozone content in each of the initial solution containers and of comparing with the set value of ozone content associated with each of the containers, wherein the data acquisition and processing means are capable of carrying out a feedback operation by controlling the at least two flow-control devices so as to reestablish the dissolved-ozone content at the desired set value.
