Resumen:
A sigmoid model is proposed for the simulation of food
temperature evolution during the processing of preserves
in low capacity sterilizers. Predicted results are compared
against a formula method (exponential), widely used in the
simulation and control of industrial processes.
The proposed model resulted to be simple and accurate for
the prediction of thermal histories of foods of different
shapes and sizes sterilized in glass jars, and may be very
useful for low volume processors. The exponential model
did not provide accurate predictions for these processing
conditions.
