The invention has the beneficial effects that: the device can realize the sterility of products (cured meat particles) before packaging and the sterility of the packaging environment, thereby realizing the commercial sterility of the packaged products without a sterilization process.
Under the action of microwaves generated by a microwave heating generator, the temperature inside the material is raised (the temperature of the external environment is kept at 120-240 ℃ after being stabilized), and the effect of curing and removing part of moisture (moisture reaches a certain degree, a moisture removal device is started, and wet air is discharged, so that the moisture is removed) in the conveying process is realized. Most of the air is introduced from the packaging unit, avoiding the ingress of material inlet air (containing microorganisms). In the curing process, the materials are heated for a long time (30-60min) at a higher temperature (120-. And the meat particles slowly move in the microwave curing device, so that the materials are uniformly and continuously turned, and the problems that the local gelatinization is caused by the nonuniform microwave heating temperature, the materials are adhered to equipment and the interference on the cleaning of the equipment before the subsequent production is caused are avoided.
