AIR SUPPLY AND EXHAUST SYSTEM FOR TUNNEL-TYPE STERILIZING DRYER

摘要

An air supply and exhaust system for a tunnel-type sterilizing dryer, comprising an indoor oven assembly (1), a quantitative air supply assembly (2) and a quantitative air exhaust assembly (3) communicating with the oven assembly (1); the air inlet of the quantitative air supply assembly (2) is disposed outdoors. The system improves the stability and controllability of indoor pressure difference and laminar flow effect, is safe and reliable to use, and avoids backflow contamination, thus improving operation environment and reducing production cost.
