FIELD: drying.
SUBSTANCE: invention relates to a nozzle blast chamber for directing incoming air flow when drying a veneer sheet. Chamber of nozzle blast comprises at least one jet nozzle (202). Jet nozzle comprises guide surface forming three-dimensional structure of holes, which is limited at its first end by inner hole (301), and at its second end - by external hole (302). Guide surface comprises first portion (306) and second portion (304), wherein first portion (306), substantially on the incoming air flow side, is convexly curved outward from the nozzle blow chamber, and second section (304), substantially on the opposite side of the structure of the holes relative to the incoming air flow, is concavely curved outward from the nozzle blow chamber. Invention also relates to a dryer comprising at least one chamber of blow nozzle.
EFFECT: invention shall ensure efficient and productive drying due to improved heat transfer.
