The beneficial effects of the invention are: 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 rises (the temperature of the external environment is kept between 120 and 240 ℃ after being stabilized), and the effects of curing and removing part of moisture (when the moisture reaches a certain degree, a moisture removal device is started, and wet air is discharged, so that the moisture is removed) are achieved in the conveying process. Most of the air is introduced from the packaging unit, avoiding the ingress of material inlet air (containing microorganisms). In the curing process of the materials, the materials are heated for a long time (30-60 min) at a higher temperature (120-240 ℃) and the principle of dry heat sterilization is utilized, so that the products (cured meat particles) before packaging are aseptic. 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.

The sub-packaging work is completely carried out in the outer shell, clean sterile air is conveyed into the outer shell by the air supply device, so that micro-positive pressure is kept in the outer shell, and the external air environment is difficult to enter the pre-packaging device and the vacuum bag packaging device by the micro-positive pressure to cause bacterial pollution, so that secondary sterilization is not needed; because equipment is numerous, the shell body can not keep absolute seal, and the air circulation in the shell body is ensured through the micro-positive pressure environment, and the dehumidification function can be realized. In addition, the screw conveyer is provided with a dehumidifying port, the dehumidifying port is dehumidified through the dehumidifier, a large amount of moisture caused by curing in the screw conveyer can be discharged, and meanwhile, due to the fact that the screw conveyer is communicated with the inside of the outer shell, air loss caused by dehumidification is supplemented by micro-positive pressure in the outer shell, and unclean air is effectively prevented from entering the screw conveyer.

During the operation of the racking machine, instant meat particles are loaded into the pre-distribution barrel through the back and forth movement of 2 material pushing plates (namely movable side plates), the pre-distribution barrel moves in a stepping manner in the process, the loading is realized through 3 times of pushing and stepping movement, the materials are ensured not to be scattered into the equipment, and the weight of the materials in the pre-distribution barrel is distributed within a certain precision range (the weight of each barrel is distributed within +/-5%). When the packaging machine works for the first time, the aseptic packaging process is realized by utilizing the aseptic conditions of higher environmental temperature and positive pressure; during subsequent work, because this simple structure is easy to be cleaned, can ensure equipment sanitization, no greasy dirt, no scattered material in dead angle department, can not form the pollution source because thoroughly clean, the carrier that the dead angle department greasy dirt, scattered material become the microorganism and breed because of not, can't realize the aseptic ization of follow-up packing.

The automated instant meat pellet production system of claim 2, wherein: the gate of feed cylinder bottom is divided the gate in advance to the side, and it includes the flashboard that matches with feed cylinder bottom cross sectional dimension in advance and sets up in the breach of dividing the feed cylinder bottom side in advance, and the flashboard is installed on feed cylinder in advance through the pivot, and it realizes that the gate is closed and is opened to advance or roll out the breach through the gate, be equipped with the torsional spring that makes the gate keep closing in the pivot, the flashboard tail end is equipped with the push rod of being convenient for promote.

6. The automated instant meat particle production system of any one of claims 1 to 5, wherein: the inclination angle of the spiral conveyor is 0-30 degrees.

7. An automatic production method of instant meat granules without secondary sterilization is characterized by comprising the following steps:

step 1, building an automatic production system of the instant meat granules as claimed in any one of claims 2-6;

step 2, starting an air supply device, and conveying clean sterile air into the outer shell to keep the micro-positive pressure state in the outer shell, wherein the pre-distribution device and the vacuum bag packaging device operate in the micro-positive pressure environment to keep the sterile environment;

step 3, starting the screw conveyor and the microwave heating generator, and continuously adding the prepared seasoning meat particles into the material inlet; the seasoning meat particles move forwards under the spiral conveying, are heated and cured in the moving process, and simultaneously complete one-time high-temperature sterilization at the curing temperature;

and 4, feeding the cured meat particles into a material distribution device through a clinker outlet, subpackaging the cured meat particles into each pre-distribution cylinder through the material distribution device, conveying the pre-distribution cylinders to a vacuum bag packaging device through an annular conveying line for vacuum bagging and packaging, and thus completing automatic production of the instant meat particles.
