The Current Research Status of New Technologies for Modern Green Grain Storage —Taking Wuhan National Rice Trading Center Co., Ltd. as an Example

To accelerate the construction of secure, green, and intelligent granaries and to enhance the level of modern management, green grain storage technologies have ushered in new developments under the backdrop of technological empowerment and the vigorous development of new production forces. This study took Wuhan National Rice Trading Center Co., Ltd. as an example reviewed and evaluated three new temperature control technologies, including photovoltaic off grid power supply technology air conditioning system, vertical thermal cortex temperature control technology in grain silos, zero energy radiation refrigeration technology, and three new insect control and insecticidal technologies by using spinosad, S-methoprene or food grade inert powder. Additionally, it was recommended to take the thermal insulation and cold insulation measures of the warehouse as the basis for the transformation of quasi low temperature warehouses, and use green grain storage technologies as the main means, such as air conditioning temperature control technology or modified atmosphere storage technology. The above new green grain storage technologies should be comprehensively applied to meet the requirements of quasi low temperature grain storage, non-fumigation grain storage, and smart grain storage. This study aimed to provide relevant references for grain storage enterprises to carry out research on the application of green grain storage new technologies.
