This invention discloses a packaging structure based on a solid-liquid two-phase food shallow dish and its temperature rise prediction model, belonging to the field of food heat treatment and packaging technology. The total volume and height of the shallow dish are fixed, and the aspect ratio of the bottom surface is selected from 1:1, 1:0.9, 1:0.8, 1:0.7, 1:0.6, and 1:0.5, corresponding to lengths and widths of 277×277 mm, 292×262.8 mm, 310×248 mm, 331.2×231.8 m, 357.8×214.7 mm, and 392×196 mm, respectively. This invention enhances sterilization intensity and accelerates the temperature rise rate of the slowest heating zone by changing the aspect ratio of the shallow dish, while keeping the volume and height constant. Simulation and experimental verification show that the shallow dish with an aspect ratio of 1:0.5 has the best temperature rise performance, effectively shortening sterilization time, reducing energy consumption, and improving food quality. The present invention also provides a temperature rise prediction model based on the packaging structure, including material parameter determination, random particle generation, three-dimensional modeling, simulation verification and multi-scheme comparison, etc., which provides a reliable design basis for efficient sterilization of solid-liquid two-phase food.
