USING THE SIMULTANEOUS CALCULATION OF TEMPERATURE TIME PROFILES AND DEL FACTORS TO PROVIDE A TEACHING PROGRAM FOR THE SIMULATION OF THE STERILIZATION OF A FERMENTER

The simulation program of fermenter sterilisation encourages students to make decisions on the heating and cooling of fermenters to achieve a required degree of sterilisation and conserve the maximum amount of a thermolabile ingredient (e.g. a vitamin). This is achieved by simult aneously calculating the Del factors for spore and vitamin destruction during the heating and cooling stage of the fermenter. The program di splays the complete temperature time profile for the sterilisation cyc le and summarises the relevant data in a table.
