Design and evaluation of ice consumption estimated system for Pseudosciaena crocea chilled chain

With the purpose of accurately measure the ice needed during the circulation process of iced Pseudosciaena crocea, heat transfer principal theory was applied to analysis the heat transfer between inside and outside of foam box, and an estimation model of ice consumption for Pseudosciaena crocea in the circulation was established based on ambient temperatures from 0℃ to 25℃. By the means of platform developed using Visual Basic, this model was applied in the system, which improved its practical application function. The accuracy of the estimation system was also verified through simulation tests under different ambient temperatures. The results showed that relative deviations of estimated values and factual values on ice consumption were in the range from 7.0% to 16.2% with an average deviation of 12.3%, and the deviation factor and accuracy factor of ice consumption estimation system were 0.778 and 1.285, respectively, which suggested the estimation system could quickly and reliably estimate the practical ice consumption during circulation process of iced Pseudosciaena crocea, and could be considered as an effective tool to monitor ice consumption during circulation.
