Natural low-temperature barn and grain storage method thereof

Abstract

The invention discloses a natural low-temperature barn. The barn comprises a barn body, a ventilation window, an air inlet, ventilation pipelines, a circulating pipeline, a third fan, refrigeration equipment, multiple first temperature sensors, multiple humidity sensors, multiple second temperature sensors and meteorological monitoring equipment. The ventilation window is formed in the upper surface of the barn body, the air inlet is formed in the lower surface of the barn body, the ventilation pipelines are buried inside grain stacks, and the first ends of the ventilation pipelines are communicated with the air inlet, wherein a first fan is arranged inside the ventilation window and used for exhausting air inside space above the grain stacks to the external environment and / or a second fan is arranged inside the air inlet and used for introducing air in the external environment into the grain stacks; the air inlet end of the circulating pipeline is also communicated with the first ends of the ventilation pipelines, and the third fan is arranged inside the circulating pipeline. The invention further discloses a grain storage method of the natural low-temperature barn. Energy is saved, the refrigeration effect is good, and temperature distribution is even.

Description

technical field [0001] The invention relates to the related technical field of low-temperature grain storage. More specifically, the present invention relates to a natural low-temperature granary and a grain storage method thereof. Background technique [0002] At present, in the process of grain storage, the cooling method that is often used is air conditioning cooling. However, the advantage of this method is that it is convenient to cool down, and the cooling speed is fast. The disadvantage is that the power consumption is huge and the operating cost is too high, which makes many grain depots unbearable. Some grain depots also use natural ventilation to reduce the temperature in the granary. This method has the advantage of saving energy, but the cooling effect is poor, the cold air is not easy to distribute evenly, and the natural ventilation is also easily affected by seasonal changes. unstable. Therefore, need to design a kind of can make full use of natural low tem...

However, the advantage of this method is that it is convenient to cool down, and the cooling speed is fast. The disadvantage is that the power consumption is huge and the operating cost is too high, which makes many grain depots unbearable.

Some grain depots also use natural ventilation to reduce the temperature in the granary. This method has the advantage of saving energy, but the cooling effect is poor, the cold air is not easy to distribute evenly, and the natural ventilation is also easily affected by seasonal changes. unstable
