AI Technical Summary
In existing fully automatic microwave sterilization and preservation equipment for cooked seafood, the seafood trays in the microwave sterilization chamber are fixed and static, which leads to uneven heating of the materials, resulting in large temperature differences in different parts of the food, incomplete sterilization, or overheating.
The equipment body is equipped with a feeding unit, a preheating and pressurizing unit, a microwave sterilization unit, a heat preservation and cooling unit, and a discharging unit along the material conveying direction. Combined with a PLC logic controller, it realizes full-process automated control. The rotating component driven by a servo motor makes the tray rotate around its own center to achieve all-round microwave irradiation. It also prevents leakage through bidirectional microwave emission from the top and bottom and a metal microwave shielding layer.
It achieves uniform sterilization of seafood, preserving its original nutrients, color, and flavor, improving production efficiency, adapting to the needs of small-batch, multi-category production, and avoiding the phenomenon of incomplete sterilization or overheating in certain areas.
