Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, specifically to an infrared heating belt drying system. Background Technology

[0002] Infrared tunnel drying ovens are high-efficiency drying equipment combining infrared radiation heating technology and a continuous conveying system. Materials enter the oven via an automatic feeding system, and the infrared radiation heating modules inside the oven heat the materials using medium-wave or long-wave infrared radiation. The materials move continuously on a stainless steel mesh belt or composite conveyor belt, receiving infrared radiation. Internal moisture or solvents evaporate upon heating and are discharged through a dehumidification system. After drying, the materials are cooled and discharged through a cooling section. Currently, when applied to continuous or intermittent drying of grouped firing plates (including tooling), existing infrared tunnel drying ovens suffer from problems such as large footprint, low drying efficiency, and inconvenient data adjustment. Therefore, an infrared-heated material belt drying system is proposed. Utility Model Content
