Abstract
A method for determining the degree of heat treatment of a liquid product in a liquid product processing system involves measuring at least a first value representing the temperature of the liquid product within a first time period; measuring at least a second value representing the flow of the liquid product within the first time period; and calculating at least a first heat treatment index value based on the first and second values, wherein the heat treatment index value is associated with a current degree of heat treatment of the liquid product.
Claims22
A method for determining a heat treatment index value for a liquid product in a liquid product processing system, the method comprising:
- measuring at least a first value representing the temperature of the liquid product within a first time period;
- measuring at least a second value representing the flow of the liquid product within the first time period;
- calculating at least a first heat treatment index value for the liquid product based on said first and second values and a predetermined pH value of the liquid product, wherein said heat treatment index value is associated with a current degree of heat treatment of the liquid product;
- and
- presenting the calculated first heat treatment index value to an operator of the liquid product processing system for monitoring.
A system for controlling the degree of heat treatment of a liquid product in a liquid product processing system, comprising:
- a first sensor unit for measuring at least a first value representing the temperature of the liquid product within a first time period;
- a second sensor unit for measuring at least a second value representing the flow of the liquid product within the first time period;
- and
- control unit being configured to calculate at least a first heat treatment index value for the liquid product based on said first and second values and on a predetermined pH value of the liquid product, wherein said heat treatment index value is associated with a degree of heat treatment of the liquid product, the control unit controlling operating parameters of the liquid product processing system based upon at least the first heat treatment index value.
