your location:the process of quick freezing turbot with liquid nitrogen tunnel quick freezing machine is as follows:
1. pretreatment: turbot fish enteringliquid nitrogen quick freezing machinebefore, pre-treatment is required, including scaling, gutting, cleaning, etc.
2. freezing preparation: place the pre-processed turbot on the conveyor belt, and the conveyor belt will send the turbot to the entrance of the liquid nitrogen tunnel quick freezing machine.
3. liquid nitrogen spraying: liquid nitrogen is sprayed onto the surface of turbot through a nozzle or spray device, rapidly cooling the surface to form a layer of ice.
4. quick freezing: the turbot continues to move forward in the tunnel, constantly contacts and absorbs liquid nitrogen, and the temperature continues to decrease until it reaches the required quick freezing temperature.
5. warming up: after the quick-frozen turbot comes out of the liquid nitrogen tunnel quick freezing machine, it needs to be warmed up to gradually increase its temperature to a suitable temperature.
only in this way can the taste and quality of turbot be guaranteed.
6. packaging: the warmed turbot needs to be packaged to avoid being polluted and oxidized by the outside world again, and to facilitate storage and transportation.
in general, the turbot liquid nitrogen tunnel quick freezing machine quickly cools the turbot and reaches the required quick freezing temperature by spraying liquid nitrogen.
this enables rapid freezing of turbot.
