Method and apparatus for monitoring a continuous cooking process based on particulate residence time
First Claim
1. Apparatus for monitoring a continuous production process in which articles are transported in a stream in which the articles are moving at various velocities in changeable sequence and the processing of the articles is dependent on residence time comprisingan elongated conduit within which articles are transported in a stream with said articles moving at different relative velocities and in different sequences with respect to one another,said articles being processed within said conduit,a plurality of simulated articles which resemble said articles and each of which is equipped with a transponder,said transponder being responsive to an external signal to produce an identifying signal,means for inserting said simulated articles into said conduit to commingle said simulated articles with articles being processed in said stream,monitoring stations downstream of said means for inserting,each said monitoring station including signal generating means to generate said external signal to activate said transponders and signal receiving means to record each predetermined transponder identifying signal,said monitoring stations being located along said conduit at spaced positions between which the residence times of said articles are to be measured,and timing means connected to said monitoring stations providing a residence time for each simulated article passing said monitoring stations.

Abstract
A method and apparatus for monitoring the residence time of food particles in a continuous flow process utilizing simulated food particles, each including a transponder having a predetermined identifying signal, to be subjected to the process along with the actual food particles. The method and apparatus relates to a continuous pasta cooking process in which a transponder in a simulated product emits an identifying signal received at various stations along the process to indicate the time of passage between the stations.

6. A process for monitoring a stream of particles which comprise a mass of particles moving at various velocities in a changeable sequence comprising the steps of:
-
providing multiple simulated particles each having an implanted miniature transponder and each having physical characteristics similar to actual particles being processed so that the simulated particles will replicate the movement of the actual particles in moving through the process, each transponder sending a predetermined identifying signal when activated by a radiated signal, inserting said simulated particles into a stream of actual particles being processed and subjecting said simulated particles to the same processing as said actual particles, monitoring the time of passage of said simulated particles between two locations in said process by obtaining data on each individual simulated particle at each location. - View Dependent Claims (7, 8, 9)
