Résumé

The method is thus remote and physically based on the heat transfer between prawns and glazing water. A number of process parameters are varied to obtain representative conditions. These parameters include: glazing water flow rate and temperature, residence time, input and output prawn temperatures, and prawn mass. Moreover, the resulting glazing fraction is estimated to be in the interval from 0.075 to 0.14. A closer study of selected performance parameters shows that the enthalpy method is most robust to environmental modifying and interfering effects in the linear interval of the prawn fillet enthalpy function (below -10 deg C). In this interval the precision (variance) of the two methods is of the same order.
