Vacuum modified atmosphere rat-free granary

Abstract

The invention discloses a vacuum modified atmosphere rat-free granary. The vacuum modified atmosphere rat-free granary adopts a warehouse body structure which is integrally arranged, the inner part of a warehouse body is divided into a grain storage space and an equipment arrangement space; the grain storage space comprises the warehouse body, a warehouse door 4 and a vacuum door sealing component, the warehouse body consists of a warehouse wall 1, a warehouse bottom 2 and a warehouse roof 3, and the warehouse door 4 is provided with a small sampling window; the equipment arrangement space is provided with a vacuum modified atmosphere equipment system, vacuum equipment, modified atmosphere equipment and an electrical control component, the vacuum equipment comprises a vacuum pump, a vacuum control component, a vacuum display component and a vacuum air bleeding device, the modified atmosphere equipment comprises a hollow fiber membrane separating type nitrogen generator, an oxygen component detector, a warehouse air balancing bag and a balancing safety valve, pipelines are used for connecting vacuum equipment, the modified atmosphere equipment, vacuum components and modified atmosphere components which are related to each other, the electrical control component is used for operating and controlling the work of all equipment and all components, and thus the vacuum modified atmosphere equipment system which is suitable for the warehouse wall 1, the warehouse bottom 2 and the warehouse roof 3 of the warehouse body is formed. Grains stored in the vacuum modified atmosphere rat-free granary are always maintained in a low-oxygen and low-humidity storage safe state, thus the rat-free and safe grain storage problem of the granary can be effectively solved, and the safe grain storage quality of the granary can be further increased.

Description

technical field [0001] The invention relates to a food vacuum air-conditioning fresh-keeping technology, in particular to the technology of adopting the vacuum low-oxygen air-conditioning technology to realize the rodent control technology and grain fresh-keeping technology of a granary. Background technique [0002] Food is the food that human beings are lazy to survive. However, the loss of grain to the market after harvest is staggering. According to the latest statistics from the Ministry of Agriculture, the post-harvest loss rate of my country's grain is as high as more than 8% every year, which is equivalent to the annual loss of my country's grain is about 50 billion catties. Take the Heilongjiang reclamation area known as the "Northern Dacang" as an example. In 2011, the total grain output exceeded 100 billion catties. According to this calculation, about half of the "Bei Dacang" in our country disappears invisible every year. In developed countries, the post-harv...

Furthermore, due to climate and environmental natural disasters, droughts in some major grain-producing countries have reduced the production of grains such as corn, soybeans, and wheat, which will cause grain prices to rise.
