AI Technical Summary

Technical Problem

Existing drying equipment cannot control the temperature of different areas within the dryer, resulting in over-drying of fruits and vegetables at the bottom, causing severe powdering and affecting their performance and quality.

Method used

The system employs a zoned temperature control module, which combines a rectangular opening, guide rails, insulation plates, and a sealing plate to achieve zoned temperature control within the chamber. Combined with a linear motor and a wire rope system driven by an electric motor, the temperature is dynamically adjusted to meet the drying needs of different fruits and vegetables.

Benefits of technology

It enables precise control over the drying degree of fruits and vegetables, reduces the risk of powdering caused by over-drying, and improves the appearance and quality of dried fruits and vegetables.
