却風の風量・風速をできるだけ均一にすることにある。In order to freeze food at a high quality, the cooling rate is increased so that the food passes through the maximum ice crystal formation temperature zone (generally 0 ° C. to −5 ° C.), and the water inside the food is removed. It is important to freeze in the state of fine particles.To achieve this, it is necessary to keep the cooling temperature as low as possible and increase the cooling rate to increase the heat transfer coefficient on the food surface, while also applying cooling air uniformly to the entire food surface. It is important. In contrast, the conventional configuration of FIG. 9 is considered to have the following problems. 1) Since the cool air discharge part on the front of the fan and the cool air suction part without the fan are located on the same plane, a short cycle occurs in which the cool air returns to the cooler side before hitting the food, and the air volume of the cool air hitting the food is small. . 2) As shown in FIG. 7, in a configuration in which one fan corresponds to a plurality of food shelves, there is a difference in the amount of cooling air supplied to each food shelf. 3) As shown in FIG. 9, the cooling air flows so as to make a U-turn on the food shelf, so that the distribution of the wind speed becomes uneven even within the same food shelf. Therefore, an object of the present invention is to make the volume and velocity of cooling air that hits foodstuffs as uniform as possible.

In addition, the food can be uniformly frozen at a uniform air volume and velocity without causing stagnation of the wind.
