The drying boxes are made in the form of hollow rectangular parallelepipeds with one end side open and a perforated upper part, and inside the second bottom and subsequent drying boxes there are vertically installed bushings with through holes connecting their upper and lower parts. The device for supplying coolant to the drying zone is made in the form of a fan. The heat carrier distributor is made in the form of a system of air ducts connecting to the open end sides of the drying boxes. The electric heaters of the coolant are installed separately in each duct at a minimum distance from the drying boxes, and the drying boxes are installed in such a way that their open end parts are consistently directed in opposite directions.
