て箱型に構成するプレハブパネル方式のものが一般的で
ある。A cooling chamber in a conventional continuous freezing apparatus is generally of a prefabricated panel type in which a flat heat insulating panel having an inner surface to which a heat insulating material is attached is assembled into a box shape.

合部に隙間があいたりするという問題があった。[0004] Since the inside of the cooling chamber must be kept clean at all times, warm water washing to wash out moisture and residues from the frozen object and sterilization by high-temperature steam are regularly performed. In a prefabricated panel type cooling room, the heat insulating material deteriorates due to temperature changes due to hot water or high-temperature steam, and the cooling effect decreases. There was a problem that there was a gap.
【０００５】また、プレハブパネル方式の冷却室は箱形
で内底面が平坦なので、洗浄排水を充分に排出すること
ができず、不衛生であるとともに残留水分による空気冷
却器への着霜量が大となるという問題もあった。Further, since the cooling chamber of the prefabricated panel system is box-shaped and the inner bottom surface is flat, it is not possible to sufficiently discharge the washing wastewater, which is unsanitary and the amount of frost formed on the air cooler due to residual moisture is reduced. There was also the problem of becoming big.

上の被凍結品に吹き付けるようになっている。In contrast to the above-mentioned conventional continuous freezing apparatus, there is also a continuous freezing apparatus in which the cooling chamber is placed horizontally and has a cylindrical shape, and its structure is, for example, as shown in FIG. A belt conveyor 33 that conveys a frozen product 32 and an air cooler 3 are provided in a cylindrical cooling chamber 31.
4 is provided so that the cool air from the air cooler is blown on the articles to be frozen on the conveyor.

することができるという利点もある。The cooling chamber comprises an outer cylinder structure 35 and an inner cylinder structure 36.
The heat insulating material 37 is provided between them, and the heat insulating material does not directly come into contact with steam at the time of high-temperature steam sterilization or hot water at the time of washing with hot water, and there is almost no risk of deterioration of the heat insulating material. In addition, there is an advantage that the washing drainage can be easily discharged to the outside from the drain pipe 38 connected to the drain port at the bottom when the cooling chamber is washed.

の冷凍処理能力が制限されるという問題がある。However, in this device, since the cross section of the cooling chamber is circular, the width and height of the air cooler 34 mounted on the conveyor 33 are necessarily small, and the cooling capacity of the air cooler is increased. Therefore, there is a problem that the refrigerating capacity of the apparatus is limited.

にある。The object of the present invention is that there is almost no risk of deformation of the cooling chamber due to washing with hot water in the cooling chamber or sterilization by high-temperature steam and a decrease in the cooling effect, and that the washing wastewater can be easily discharged to the outside. It is an object of the present invention to provide a continuous freezing apparatus which is hygienic, has a sufficient installation space for an air cooler and a conveyor device, and has a high freezing treatment capacity.

I do. The frozen product conveyed by the conveyor device alternately passes through the strong wind zone and the weak wind zone, so that the surface portion is cooled by heat transfer from the cold wind in the strong wind zone, and the cold heat of the surface portion is heated in the weak wind zone. Since it reaches the core by conduction, it is frozen in a state where the temperature difference between the surface portion and the core portion of the frozen product is small, and the quality of the frozen product is degraded due to uneven freezing and the surface of the frozen product is cracked. There is no such thing.

保冷効果が低下するおそれは殆どない。Since the continuous freezing apparatus according to the present invention has the above-described structure, the following effects can be obtained. Since the cooling chamber has a double structure with an insulating material provided between the outer structure and the inner structure, the insulating material does not come into direct contact with hot water during hot water washing or steam during high-temperature steam sterilization. Quality and deformation can be prevented. Therefore, there is almost no possibility that the cooling effect of the cooling chamber is reduced due to a temperature change during hot water washing or high-temperature steam sterilization.
