Anti-gravity heat pipe used for low-temperature grain storage and low-temperature grain storage method

Abstract

The invention relates to a low-temperature grain storage device and method, in particular to an anti-gravity heat pipe used for low-temperature grain storage and a low-temperature grain storage method and belongs to the technical field of low-temperature grain storage. The anti-gravity heat pipe sequentially comprises an outer shell, a liquid absorbing core, an interlayer and a liquid work medium from outside to inside and is sequentially divided into a condensation section, a heat insulation section and an evaporation section from bottom to top. The anti-gravity heat pipe has the advantages of being simple in structure, convenient to move and use, high in heat transfer efficiency, good in stability and high in safety. According to the low-temperature grain storage method, the temperature of the inner layer of a stack of grain and the temperature of the outer layer of the stack of grain are balanced by means of heat transfer of the anti-gravity heat pipe, and the low-temperature grain storage method has the advantages of being environmentally friendly, capable of saving energy, safe, reliable and the like.

Description

technical field [0001] The invention relates to a low-temperature grain storage device and method, belonging to the technical field of low-temperature grain storage, and in particular to an antigravity heat pipe for low-temperature grain storage and a low-temperature grain storage method. Background technique [0002] my country is the world's largest grain producer and consumer country. With the improvement of people's living standards, issues such as grain quality and food safety have gradually become the focus of people's attention. Due to the weak respiration of grains stored at low temperature, the dry matter consumed by respiration is less, and the protein, carbohydrates, lipids, and acidic substances in the grains change slowly, reducing nutrient loss, and the quality of the grains is relatively good. Low-temperature grain storage not only ensures the quality of grain, but also can effectively inhibit the growth of insects and molds, reduce the use and pollution of ch...

Problems solved by technology

However, it is not easy to build modern granaries on a large scale. The design and construction of ordinary large granaries is often limited by climate characteristics and geographical location, and requires expensive and complex refrigeration equipment, which consumes a lot of energy, increases the cost of grain storage, and increases the cost of storage.
