Problems solved by technology

The method of using natural ventilation has poor cooling effect, limited by seasons and excessive water loss; mechanical ventilation low temperature and grain refrigeration equipment consume a lot of energy and are expensive, which restricts the application and promotion of this kind of low temperature grain storage method

There are also studies on the use of solar energy for low-temperature grain storage, but due to the time characteristics of solar energy, the solar low-temperature grain storage system has great limitations, especially in summer evenings and rainy seasons, when the refrigerator cannot work normally, affecting low-temperature grain storage. effect, and the cost of solar heat collection system is relatively high, which is a very unfavorable factor

In addition, there is also the use of deep well water for low-temperature grain storage. This technology is to drill a deep well outside the granary, then use a deep water pump to pump cold water into the granary, and provide cold air to the granary through an air conditioner. The problem of scarcity and pollution, the country has not advocated the use of this method
