Description

  The present invention relates to a cooling device for cooling an object to be cooled such as a food.

  Conventionally, as a cooling device for cooling a food or other object to be cooled, a cold air forced circulation system is used in which air cooled by a cooler such as a cooling coil is forcibly fed by a fan to a cooling chamber in which the object is placed. Are known. Also, as a cooling device that does not use a forced circulation system of cold air, a cooling fan is disposed on the front of the cooler, the space in front of the cooling fan is a cooling chamber, and the cooling air present in the vicinity of the cooler is used as a cooling fan. There has been proposed a system in which suction from the rear surface is made to flow to the cooling chamber (see, for example, Patent Document 1).

  In the cooling device which does not perform the forced circulation system of the cold air, the cooling air of the cooling chamber is not forcibly circulated to the cooler, and the boundary of the air layer between the cooling unit including the cooler and the cooling chamber Heat exchange by collision between molecules takes place, and the water vapor pressure in the cooling chamber is saturated and does not dry, so a slight amount of water on the surface of the object to be cooled instantly freezes the thin ice barrier over the entire surface Since ice crystals in the object to be formed can be held in micro units, it is believed that denaturation of the object to be cooled can be prevented.
