Description

Technical Field

[0001] This utility model relates to the field of ventilation system technology, specifically a corn storage anti-mold ventilation system. Background Technology

[0002] As one of my country's major grain crops, the quality assurance of corn during post-harvest storage directly impacts food security and agricultural economic benefits. During storage, the interaction between the moisture content of corn kernels and the temperature and humidity of the storage environment easily fosters the growth of molds (such as Aspergillus flavus and Fusarium), leading to kernel deterioration and quality degradation. This not only causes storage losses but may also produce harmful substances like aflatoxin, endangering human and animal health. Therefore, ventilation and humidity control, as well as temperature control and mold prevention, have become core technical requirements for corn storage.

[0003] Existing methods for preventing mold growth in corn storage mainly include natural ventilation and mechanical ventilation. Natural ventilation relies on the temperature and humidity difference between the inside and outside of the storage area to create air convection. Although it is inexpensive, it is significantly limited by environmental conditions, has low ventilation efficiency, and is difficult to quickly reduce moisture in high-humidity areas inside the storage area. Especially during rainy seasons or in enclosed storage environments, it cannot effectively inhibit mold growth. Mechanical ventilation mostly uses fans to force airflow to achieve air replacement, but it suffers from uneven ventilation, and corn is still prone to dampness and mold. Therefore, a corn storage mold prevention ventilation system is proposed. Utility Model Content
