AI Technical Summary

Technical Problem

In existing solar drying devices, the materials are densely packed, preventing hot air from penetrating, resulting in uneven heat distribution and low drying efficiency, which makes it difficult to meet the needs of large-scale and high-efficiency drying.

Method used

It adopts a three-stage stepped frame structure, combined with double-layer coated vacuum glass heat collection tubes and superheated tube arrays, and with heat collection modules and reflectors that can be switched at different angles to achieve uniform heat distribution and smooth airflow. Combined with staggered square tubes, openable and closable inclined mesh plates and cam-driven adjustment structure, it ensures uniform heating of materials and smooth airflow.

Benefits of technology

It achieves uniform heating of materials and smooth airflow, improving drying efficiency and quality. The device has a compact structure, is energy-saving and environmentally friendly, and operates stably and reliably.
