AI Technical Summary

Technical Problem

Existing pre-cooling warehouses are inadequate in preventing microorganisms. The ventilation system is not effective in blocking external microorganisms, making fruits and vegetables susceptible to microbial attack and spoilage during pre-cooling storage.

Method used

It employs a sterilization chamber, ultraviolet sterilization lamps, a multi-stage air filtration system, and a sealing mechanism. Through multi-stage air filtration and ultraviolet sterilization, combined with a quick-release mechanism and an active sealing mechanism, it achieves efficient purification and sealing of the air entering the pre-cooling warehouse, preventing microbial contamination.

Benefits of technology

It achieves efficient purification of air entering the pre-cooling warehouse, extends the shelf life of fruits and vegetables, reduces maintenance difficulty, improves the airtightness and microbial prevention capabilities of the pre-cooling warehouse, and ensures the quality of fruits and vegetables.
