The dehydration processes kinetics laws of squid and octopus, as a separate capillary-porous colloidal bodies group, were studied using industrial methods of energy supply. The research included an analysis of the influence of the species and size-mass composition of the material as well as operating conditions in the process of removing moisture from the product. The method was used to find critical points corresponding to a certain level of humidity in a specific period of time. It was found that cephalopods constant rate moisture removal is significantly longer compared to fish raw materials. For fish, the first critical point is reached at the end of a period of constant dehydration rate; for cephalopods, there is only one critical point during the entire moisture removal process. A mathematical model is proposed for finding critical humidity in the process of dehydration of cephalopods. The authors of the study developed similarity numbers in order to reduce the set of dehydration curves of cephalopods of different composition and geometric sizes under conditions of various methods and rigidity of heat treatment into one generalized dependence. The obtained patterns provide some ways to design and optimize heat and mass transfer processes and devices in food engineering.
