As can be seen from the kinetics curves of cephalopods dehydration, regardless of the thermal action method on the processed material the nature of the processes is identical. At the same time, the rate of dehydration increases with a decrease in the specific load on the carriers or an increase in the specific surface of the processing objects (Fig. 3). In order to identify critical moisture, the dehydration kinetics curves were transferred to semi-logarithmic coordinates of the form lgra,- = f r ,) . Graphs in this form for the analysis of the process can be considered as broken straight lines. Fig. 4 shows an example of a squid dehydration kinetics curve constructed in a semi- logarithmic anamorphosis. 2.6 2.5 2.4 3 2.3 2.1 2.0 i m k, a \Г N 10 20 30 т. inin 40 50 60 Fig. 4.

Кривая кинетики обезвоживания кальмаров в полулогарифмических координатах (источник: составлено авторами) Mathematical processing of semi-logarithmic dependencies lgra; = f r ) allowed us to determine critical points for a set of dehydration curves of cephalopods. The presence in all studied cases only one critical moisture rnki to find which the linear regression relationship is proposed юй = 0.091ю„268. (3) The research suggested the generalizing of the cephalopods dehydration kinetics curves with completely different methods of energy supply. In order to generalize the cephalopods dehydration kinetics curves, the decision was made to use dimensionless similarity numbers (criteria - simplexes) of the species (4) Many particular cephalopods dehydration kinetics curves under various methods and modes of heat treatment were combined into one generalized curve (Fig. 5). As can be seen from Fig. 5, the partial kinetics curves of cephalopods dehydration with different methods of energy supply can be described by one generalized dependence. Having used the data processing Datafit 9.1.32 mathematical description of the nonlinear regression dependency with the use of non-dimensional simplices is proposed f „ V1158 = 2.296 1+ - (5) 1'k i / For dependency (5) Fisher criteria is 5273, the significance of the numerical coefficients is 99.9 %, which generally indicates a significant relationship between the variables in the equation. 463
