Several oil-proof blow pipes 8 are arranged in sequence along the forward direction of the conveyor 2 and are horizontally installed in the cooling front part 4. The air outlet of the exhaust fan 10 is connected to the air inlet of the oil-proof blow pipe 8 through the air supply pipe 9. The cooling rear part 5 is connected to the air inlet of the exhaust fan 10 through a recovery pipe 17.

[0031] The three curtain plates 3 divide the cooling tunnel 1 into a cooling front part 4 and a cooling rear part 5, and at the same time play the role of reducing the leakage of cold air. The cooked food is placed on the conveyor 2, and the cooked food passes through the cooling front part 4 and the cooling rear part 5 in turn through the conveyor 2, completing the process of heat exhaust precooling and rapid cooling to achieve the effect of rapid cooling, and the air blowing mechanism 6 guides the excess cold air in the cooling rear part 5 into the cooling front part 4.

The guide plate 12 can be used to convert the downward wind direction to upward and blow it onto the cooked food on the conveyor 2 to achieve a cooling effect, and some grease can also be temporarily stored for easy discharge.

[0035] Preferably, the guide plate 12 is a V-shaped plate.

[0036] Changing the downward wind direction to an upward wind direction to both sides is conducive to the contact between cold air and cooked food.

[0037] Preferably, the guide plate 12 is provided with an oil outlet pipe 13 communicating therewith.

[0038] The grease or marinade falling into the guide plate 12 is convenient to discharge.

[0039] Preferably, the inner cavity of the guide plate 12 is inclined from one end to the other end.

[0040] Grease or marinade flows from one end of the inner cavity of the guide plate 12 to the other end, and is conveniently collected and discharged from the oil outlet pipe 13 .

[0041] Embodiment three:

[0042] On the basis of the above embodiments, this embodiment shows that the rapid cooling mechanism 7 includes a cooling pipe 14 and an air distribution pipe 15. The cooling pipe 14 is installed in the cooling rear part 5 and its air inlet end is connected to the cold air end of the refrigeration equipment 16. The air inlet end of the air distribution pipe 15 is connected to the air outlet end of the cooling pipe 14, and the air distribution pipe 15 is located above and below the upper belt surface of the conveyor 2.

[0043] The air distribution duct 15 supplies cold to the cooked food from above and below the upper belt surface of the conveyor 2, and the cooling is uniform and fast.

[0044] Preferably, an air collecting hopper 18 connected to an external negative pressure device is installed in the cooling front part 4.

[0045] The air collecting hopper 18 can extract the hot air in the cooling front part 4 with the help of external negative pressure equipment (such as an exhaust fan) to achieve the purpose of rapid cooling.

[0046] Preferably, the curtain plate 3 is composed of a partition plate 31 and a blocking curtain 32 installed in the partition plate 31 .

[0047] Under the premise of not affecting the conveyor 2 and the forward movement of the cooked food thereon, the curtain 32 (soft food-grade plastic) can reduce the leakage of cold air.

[0048] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein.
