1、granary storage need to pay attention to what?

A granary is a building used to store grain and meet the basic functional requirements of safe grain storage. The environment of grain storage needs to have the favorable characteristics of low temperature and low oxygen, because in the process of grain storage, due to the respiration of grain and microorganisms, the oxygen content in the pores of the grain pile gradually decreases and the carbon dioxide content gradually increases. When the consumption of oxygen and the accumulation of carbon dioxide reach a certain level, the intensity of food respiration, the process of biological oxidation reaction, the growth and development of aerobic microorganisms and the life activities of warehouse pests are all inhibited, which is conducive to the maintenance of food quality.

2、What methods are used to inhibit microorganisms and pests?

Green nitrogen-filled grain storage technology is a set of insecticidal, mold, preservation, storage, safety, green environmental protection and other advantages in one, and easy to implement green grain storage method. Green nitrogen-filled grain storage technology is a new technology used in grain storage. Nitrogen widely exists in the air of nature, which is non-toxic and harmless to human body. It is an inert gas that does not react with any substance at room temperature. It has excellent characteristics such as green, safe and pollution-free. Nitrogen, an inexhaustible natural substance, is of great significance as a modified atmosphere storage medium for grain. With the deepening of the application research of green nitrogen-filled grain storage technology, the advantages and potential of this technology are further revealed, after filling high-purity nitrogen to form a high-nitrogen and low-oxygen storage environment in the grain pile, not only caused the stored grain pests to suffocate quickly due to lack of oxygen, effectively inhibit the growth and reproduction of stored grain microorganisms, but also have a good control effect on the first food stored grain pests such as beetles, corn elephants, corn elephant, pest mortality rate of 100.

3、Why choose nitrogen filling method?

① Nitrogen grain storage technology has excellent storage characteristics of insecticidal and fresh-keeping dual effects, which is an advantage that all known grain storage chemicals and technologies do not have, and has attracted wide attention from delegates from all over the world. Green nitrogen-filled grain storage technology is called "another revolution in grain storage technology", it is also known as "the advanced green storage technology that only needs air and electricity to kill, preserve and store the stored materials". Green nitrogen-filled grain storage technology has played a revolutionary role in the world's green grain storage, and has a significant and far-reaching impact on other storage industries.

② Nitrogen gas regulation grain storage technology, that is, nitrogen and oxygen in the air are separated by nitrogen making mechanical equipment, and the separated nitrogen is transported to the closed grain pile by means of ventilation pipe network and the oxygen in the grain pile is replaced, so that the grain pile is in a state of high nitrogen and hypoxia (or hypoxia) for a long time, and the stored grain pests and mold growth and reproduction in the grain pile can be killed without using chemical agents, thus realizing safe grain storage.

③Through the combination of intelligent temperature control and nitrogen gas control technology, the grain pile is kept in a low grain temperature, low humidity and low oxygen state for a long time, and the effect of inhibiting the reproduction and infection of insects and mildew is obvious. It can effectively kill the serious resistant insects such as rusty red flat grain thieves and book lice, especially the growth and breeding effect of book lice and mites is obvious, and the phenomenon of mites is basically eliminated. At the same time, under the low temperature environment, the grain situation is more stable, avoiding large-area heat generation, damp heat accumulation under the film, condensation, verdure and other phenomena, basically eliminating the hidden dangers of grain storage safety.

4、The basis of nitrogen filling time?

For grain storage, the most important thing is the control of environmental conditions, in the process of grain storage, it is necessary to measure the oxygen content of the grain pile in the warehouse, in order to understand the parameters of grain storage conditions in time to limit the growth and reproduction of bacteria and microorganisms, so as to avoid causing spoilage. To ensure that the granary oxygen or oxygen-free environmental conditions, it is necessary to use the oxygen sensor to measure the oxygen content in the gas, once the oxygen concentration exceeds the limit value, it can alarm through the control system, and then manually or automatically start the inflation (nitrogen) operation, until the measured value of the oxygen sensor is less than the limit value.
