Unitized storage granary and storage method thereof

Abstract

The invention discloses a unitized storage granary which comprises at least one layer of compartment, wherein the compartment of each layer comprises a plurality of storage units with independent and controllable storage conditions, and the storage capacity range of each storage unit is 5-1,000 tons; and the compartment of each layer comprises an operating area for independently carrying out feed and delivery for one or more storage units. Each storage unit with independent and controllable storage condition comprises a temperature monitoring system, a humidity monitoring system, a gas component monitoring system, a ventilation monitoring system and/or a fumigation system. Each storage unit has heat insulation and/or airtight function. The operating area can be arranged at two sides, one side or the middle of the compartment. Fixed and/or mobile conveying equipment is arranged in the operating area. The unitized storage granary has the advantages of prolonging the storage life of grains, reducing energy consumption, reducing the consumption of chemical fumigant and reducing environmental pollution; and because of the storage units, the storage units are mutually separated with the operating area, mutual influence is avoided, scientific management is facilitated, and the operating cost is saved.

Description

technical field [0001] The invention relates to the field of grain storage, in particular to a unitized storage granary and a storage method thereof. Background technique [0002] Grain is an important agricultural product and an important resource related to the national economy and the people's livelihood. The storage of finished grain is an important means to ensure the circulation of grain and respond to market fluctuations. Finished grain storage has several characteristics: 1. First, it is stored in and out of the grain warehouse in batches, and the quantity and storage period of each batch are not fixed; 2. There are differences in the variety, grade, and safety status of each batch of stored grain; 3. Due to the existence of For the above differences, the storage conditions of each batch of grain are different, and the quality preservation measures are also different. Each batch of grain needs independent quality preservation measures and cannot affect each other; 4....

AI Technical Summary

Problems solved by technology

Although this method has the advantage of a high degree of automation, it also has the following problems: ① Due to the large storage space and unstable storage conditions, it takes a lot of energy to maintain stable conditions such as temperature and humidity; ② Due to the large capacity of a single warehouse , cannot adopt independent storage conditions and storage techniques for each batch; ③The storage conditions of other batches of grain will be adversely affected when one batch of grain enters and exits the warehouse; ④If fumigation technology is applied in the grain storage process, chemical fumigation The agent will cause corrosion to many electrical equipment in the three-dimensional warehouse, thus affecting its reliable operation

[0008] (1) When the room temperature storage method is used in the building warehouse, the existing problems are: the temperature of the grain is greatly affected by the external temperature, and the temperature of the grain is also high when the external temperature is high, the physiological activities of the grain itself and the development of insects and molds are rapid, the storage period of the grain is short, and long-term storage It will affect the quality of grain; in order to inhibit the development of insect mold, chemical fumigants must be put into the grain pile, which will cause risk factors of food pollution; in order to achieve low oxygen, the grain pile must be airtight, requiring a large amount of labor ; After the airtight treatment fails, the fumigant gas may leak into the surrounding environment, causing harm to the personal safety of the workers

[0009] (2) When low-temperature storage technology is used in building warehouses, the existing problems are: due to the large area of ​​a single warehouse, which is far greater than the workload of a single batch, resulting in the mixing of multiple batches and varieties of grains in one warehouse. In the situation of storage, it is not convenient to take independent monitoring measures for grain types and batches; in addition, when one batch of grain enters and exits the warehouse, it will adversely affect the storage environment of other batches of grain, which is not conducive to Scientific management can not achieve the purpose of saving energy and reducing consumption, which increases operating costs; when grains stored at low temperature are out of the warehouse, due to the large temperature difference between inside and outside, it will cause grain condensation, and increasing its temperature on the spot will affect the storage of other batches of grain Therefore, before the grain leaves the warehouse, it can only be transported to the separately built Susu warehouse to restore normal temperature, and then leave the warehouse, which causes a second move and increases the amount of manual and mechanical work.
