PROCESS AND DEVICE FOR INVESTIGATING AND CONTROLLING CHANGES OF STATE OF A LIQUID OR GELATINIZED MEDIUM BY DIFFERENTIAL THERMAL ANALYSIS

摘要

Method of study and control of changes of state of a liquid or gelled medium, for differential measurement of the thermal characteristics of said medium. two probes, preferably platinum resistance is used. For one of them, it brings energy to the environment. The temperature control of the two probes to discriminate the effects due to the state change strictosensu phenomenon of what is due to a change in temperature. Signal processing is carried out using a microcomputer. Examples for gelatin solutions and cold renneted milk are given.
