Description

Technical Field

[0001] This utility model relates to the field of circulating drying technology, specifically a tunnel-type hot air circulating drying structure. Background Technology

[0002] Hot air circulating ovens generally have heating elements and circulating fans. Tunnel-type hot air circulating ovens are relatively long and can dry a large number of objects with high drying efficiency.

[0003] Existing tunnel-type hot air circulating drying ovens typically have dustproof mesh panels at the natural air inlet. After prolonged use, the surface of these mesh panels easily accumulates filtered dust, resulting in poor ventilation. The natural air can easily carry dust into the inside of the tunnel, further hindering the drying effect. The dustproof mesh panels are also difficult to clean themselves. Furthermore, when the heated natural air blows air into the objects inside the tunnel for drying, the concentrated flow of hot air makes it difficult to heat the objects evenly, affecting the drying efficiency. Additionally, dried materials tend to accumulate inside the equipment, leading to difficulties in subsequent maintenance and cleaning. Therefore, a tunnel-type hot air circulating drying structure is proposed. Utility Model Content
