The temperature of the output cold air rises after freezing the food, so that the temperature requirement for quick freezing cannot be met, and it is difficult to effectively utilize the cold air after absorbing heat, thereby reducing the energy efficiency of the tunnel quick-freezing machine, and the existing tunnel quick-freezing machine can usually only process quick-frozen food, affecting Diversification of food processing; This technical solution can solve the above problems, and the specific working method is as follows: the food for quick freezing is transported to the inside of the feeding shell 2 through the action of the sealed feeding mechanism, and the food is made to fall on the top of one end of the conveying mesh belt 4, and the conveying mesh belt 4 is used to drive the food to move to the inside of the discharging shell 3 through the action of the mobile conveying mechanism.

[0038] Working principle of the present invention:

[0039] The food for quick freezing is transported to the interior of the feeding shell 2 by the action of the sealed feeding mechanism, and the food is made to fall on the top of one end of the conveying mesh belt 4.

In the process of moving and conveying, the air outlets of multiple air coolers 6 are used to output cold air vertically downward to quickly freeze the food, and the sealing frame 5 is used to prevent the leakage of cold air. After quick freezing, the food is transported to the interior of the discharging shell 3 by the conveying mesh belt 4, and is discharged by the sealed feeding mechanism on the discharging shell 3. The air cooler 6 outputs cold air to the food above the conveying mesh belt 4. The cold air contacts the food vertically downward and absorbs heat after quick freezing the food. The cold air after absorbing heat moves along the pores on the surface of the conveying mesh belt 4 to the bottom of the quick freezing shell 1, and then the cold air after absorbing heat is guided and transported to the exhaust hole 8 by the action of the guide mechanism, and tilts downward along the connecting pipe 9 to the inclined circular pipe 7. The food inside the inclined circular tube 7 is continuously outputted from one end thereof, and the food for cooling and freshening is poured into the inclined circular tube 7 along the upwardly inclined end of the inclined circular tube 7. The inclined circular tube 7 is rotated unidirectionally by the action of the unidirectional rotating mechanism, and the food inside the inclined circular tube 7 moves along the inclined direction of the inclined circular tube 7 due to the movement tendency generated by the rotation and inclination of the inclined circular tube 7, so that the food inside the inclined circular tube 7 and the cold air after absorbing heat move in the opposite direction, and the cold air after absorbing heat and the food inside the inclined circular tube 7 are countercurrently contacted, so that the cold air that does not meet the quick-freezing temperature requirement contacts and absorbs heat from the food inside the inclined circular tube 7, thereby chilling the food inside the inclined circular tube 7, thereby continuing to utilize the cold air used for quick freezing, increasing the utilization rate of the cold air and improving the energy efficiency of the air conditioner 6, and making the quick freezing and chilling of the food proceed synchronously through the operation of the conveying mesh belt 4 and the inclined circular tube 7, and carrying out corresponding refrigeration processing according to the processing requirements of different foods, thereby ensuring the diversification of food processing.
