  • THROUGH-AIR DRYING APPARATUS
    Publication number: 20210062424
    Abstract: The disclosure is directed towards a through-air drying system comprising a hood and a rotatable cylinder with a porous cylindrical deck. The system includes a seal, and more particularly a seal along the lateral edges of the system. The seal generally prevents the exhaust of drying medium from the system through the gap between the hood and the rotatable cylinder and enables the system to be operated at positive air pressure. The seal may be formed by providing the hood with an axial hood flange, which extends at least partially along the bottom edge of the hood and overlaps an axial annular flange disposed on the cylinder when the hood is in a closed and sealed position.
