【発明の詳細な説明】 本発明は冷凍庫等の断熱筐体に収納された冷凍食品を−
４０℃位に冷凍保存する冷凍食品の凍結方法に関する。[Detailed Description of the Invention] The present invention provides frozen food stored in a heat insulating case such as a freezer.
This invention relates to a method for freezing frozen food that is stored frozen at about 40°C.

従来、冷凍庫等の断熱筐体に収納した冷凍食品を冷凍す
る方法としては、冷却器で熱交換された冷気を送風機で
循環させる強制循環方法と、そのまま対流させる自然対
流方法とがある。Conventionally, methods for freezing frozen foods stored in an insulated casing such as a freezer include a forced circulation method in which cold air that has been heat exchanged with a cooler is circulated by a blower, and a natural convection method in which it is directly caused to circulate.

これらの方法は食品を冷気で包囲するようにして冷却す
るため、食品に接触する冷気は限定され大部分の冷気は
有効に利用されてＬ・なかった。These methods cool the food by surrounding it with cold air, so the amount of cold air that comes into contact with the food is limited, and most of the cold air is not used effectively.

従って、この方法を用Ｌ・た断熱筐体では食品の中心部
を凍結する迄相当の時間を要し、急速凍結ができなかっ
た。Therefore, with the heat-insulated casing using this method, it took a considerable amount of time to freeze the center of the food, and rapid freezing was not possible.

上部に形成して（・る。The present invention was invented in view of the above points, and an embodiment thereof will be described below with reference to the drawings. 1 is a heat insulating casing body for a freezer or the like having an opening on the front side, which can be opened and closed at the opening. A cooler 4 is provided in the center of the side wall of the refrigerator interior 3, fans 5 are provided above and below the cooler, respectively, a suction port 6 is provided at a position facing the cooler, and A cooling chamber 9 is formed by providing a partition plate 8 having air outlets 7, 7 formed at a position facing the fan along the side wall, and a compressor that constitutes a refrigeration cycle together with the cooler. 10. A machine room 12 in which a condenser 11 and the like are installed is formed in the upper part of the main body.

この冷気は吸込口６より冷却器４に至り熱交換され吹出
口７，７より再び庫内３に吹き出される。This cold air reaches the cooler 4 through the suction port 6, undergoes heat exchange, and is blown out into the refrigerator interior 3 through the blow-off ports 7, 7.

従って、庫内３の冷気は常に乱流状態に維持されてＬ・
るから、食品１４，１４．．．への冷気の接触が増大し
食品を急速に冷却し凍結できる。Therefore, the cold air inside the refrigerator 3 is always maintained in a turbulent state and L.
Food 14, 14. ．． ．． Increased cold air contact with the food allows for rapid cooling and freezing of food.

うにしたものであるから、食品は乱流状態のより多くの
冷気と接触でき中心部を凍結される迄の時間は短くて済
み、急速凍結が可能となり且つ冷気の有効利用が図れ、
需要に応じた食品を早く提供できる。As described above, the present invention provides a cooler in the center of one side wall of a heat insulating housing, a fan above and below this cooler, a suction port in a position facing the cooler, and a fan in a position facing the fan. A cooling chamber is formed by providing a partition plate with an air outlet along the side wall, food is placed on a number of shelves arranged in the refrigerator, and cold air is blown toward the food. Since the food is frozen by stirring the refrigerator to maintain a turbulent flow inside the refrigerator, the food can come into contact with more cold air in the turbulent flow, and the time until the center is frozen is shortened. This enables quick freezing and makes effective use of cold air.
Food can be quickly provided according to demand.
