Beam, while the humidity in the stage is controlled 95 ± 2%；
In 7th stage, during negative catalysis, when the central temperature of negative catalysis object is at 2 ± 0.1 DEG C, temperature controller automatically controls stage knot
Beam, while the humidity in the stage is controlled 95 ± 2%；
When above each stage running terminates, temperature controller is automatically converted to the fresh-keeping stage, while controlling temperature in 0-4 DEG C, control
Humidity is 80 ± 2%；
Step 3, cleaning: after negative catalysis, discharging of goods simultaneously clears up sterilization treatment behind negative catalysis room.
10. the negative catalysis method of chilled meat negative catalysis device according to claim 9, it is characterised in that: each stage in step 2
When operation, the refrigeration unit and humidifier linkage control.
