Grain storage barn and control system thereof

Abstract

The invention discloses a grain storage barn. The grain storage barn comprises a storage barn body, a sampling detection component and a freshness keeping component, wherein the storage barn body comprises a granary and a transportation barn, the transportation barn and the granary are separated by a cylindrical division plate, a flood dragon shaft is vertically installed in the transportation barn, and an inner wall of the transportation barn is further provided with an electric heating plate; the sampling detection component comprises a sampling barrel, a second motor, a slipway and a moisture detector, the freshness keeping component comprises a nozzle, a spray pipe, a material drawing pump and a storage box, and the nozzle is arranged at the top of the transportation barn, directly faces an opening at the top of the division plate, and is connected with the spray pipe. An independent transportation barn is arranged in the grain storage barn, the flood dragon shaft is utilized to circularly transport grain, heating, drying and spraying a freshness keeping agent are carried out on the grain when the transportation is conducted, the grain in the storage barn can be kept dry over a long period of time, the grain freshness is maintained for a long time, the whole system runs automatically, the human power is not required, and the human resources are saved.

Description

technical field [0001] The invention relates to the field of grain storage equipment, in particular to a grain storage bin and a control system thereof. Background technique [0002] my country is the world's largest producer and consumer of rice, especially rice, as a traditional food in my country, its nutrition and taste play an important role in the diet. In the circulation of grain, the storage of grain is the most important thing. [0003] In the process of grain storage, taking rice as an example, since rice is not protected by a husk, nutrients are directly exposed to the outside, therefore, it is sensitive to the influence of external temperature, humidity and oxygen, and has strong hygroscopicity, and pests and molds are easy to infect. Harmful, it is easy to cause the accelerated metabolism of nutrients; there are more rice bran and broken rice in rice, which block the pores of the rice pile, and the internal heat is not easy to dissipate; there are more fat in t...

Problems solved by technology

[0003] In the process of food storage, taking rice as an example, since rice is not protected by a husk, nutrients are directly exposed to the outside, therefore, it is sensitive to the influence of external temperature, humidity and oxygen, and has strong hygroscopicity, and pests and molds are easy to infect. Harmful, easy to lead to accelerated metabolism of nutrients; there are more rice bran and broken rice in the rice, which block the pores of the rice pile, and the internal heat is not easy to dissipate; there are more fat in the bran powder, which is easy to oxidize and decompose, making the rice The acidity of the rice increases, so the rice is prone to moisture, heat, mold, and insects, and it is not resistant to storage

[0004] However, the existing granary has poor airtightness and is prone to moisture during long-term storage, which has a great impact on grain quality. Therefore, it is necessary to regularly turn over the sun and remove moisture, which is time-consuming and laborious.
