Method and system for residence time measurement of simulated food particles in continuous thermal food processing and simulated particles for use in same

摘要

A method of generating a residence time measurement of a particulate-containing food product while passing the product as a continuous stream through a thermal processing apparatus is described. The method includes the steps of inserting at least one detectable particle, and preferably many detectable particles, tagged with at least one magnetic implant into the stream at pre-selected intervals; detecting the at least one implant using at least one sensor located at a detection point downstream from a location of the inserting of the at least one detectable particle; determining a time of passage of the at least one detectable particle in the stream using output from the at least one sensor; and generating a residence time measurement for the stream using the time of passage for the at least one detectable particle. The method also includes the use of multiple sensors for detecting the implants. A suitable system and detectable particle for carrying the method are also described.
