MULTILAYER-TYPE CONVEYOR DRIER, PARTICULARLY FOR TABULAR PRODUCTS Russian patent published in 2009 - IPC F26B15/12 F26B21/02 

FIELD: heating, drying.

SUBSTANCE: invention concerns multilayer-type conveyor drier, particularly for tabular products. Drier includes devices, particularly rollers or belt devices for product transportation inside drier. Drier includes several sections placed in sequence along the product transportation course and including housing, with drying air circulating in forced mode in the sections, and each drier section includes central heat source and several axial fans positioned vertically each over the previous one in ventilation shaft. Fans can supply drying air directly to inlet holes located preferably in pairs over and under transportation device of respective jet box layer for product blasting and return suction of drying air saturated with moisture through at least one heat source. Jet box side opposite to ventilation shaft ends in air shaft for drying air saturated with moisture, leading to first regeneration chamber of for drying air saturated with moisture; housing of each section encases first drying air regeneration chamber equipped with heat source, positioned vertically over second chamber encasing section layers. Suction channels are made in all layers at both sides near the ventilation shaft to connect first chamber through definite inlet orifice to suction zone of respective axial fans.

EFFECT: unified supply of drying air to each drier section, homogenous residual humidity of products in the end of drying.
