PROBLEM TO BE SOLVED: To provide a cooling device for a cooling rack truck which efficiently cools viscous material placed on a rack, through trays, having a plurality of shelves, reduces dispersion of cold air to the outside, and contributes to an environmental improvements of a job site by reducing undesired sound. SOLUTION: A cooling truck 10 has a closed structure by forming openings 11a, 11b at front and rear side surfaces, respectively, and covering the other side surfaces with metal side plates 12. A plurality of shelves 13 are formed with a given interval therebetween inside the cooling truck 10. Each of the shelves 13 is constituted so that a tray 14 accommodating heated and melted viscous material can be taken in and out through the openings 11a, 11b. The side edges of the front and rear openings 11a, 11b of the cooling truck 10, respectively, are provided with a sealing member 15 which is able to airtightly and mutually connect the openings 11a, 11b, respectively. The sealing member 15 consists of a hollow metal frame 16, and an elastic member 17 made of sponge or the like which is attached to the outer side surface of the frame. |
