Grain storage refrigeration house and grain storage method

Abstract

The invention relates to a grain storage refrigeration house and a grain storage method, the grain storage refrigeration house comprises a grain storage bin body, a sealed grain storage refrigerationhouse is arranged in the grain storage bin body, grain is stored in the grain storage refrigeration house, and at least one set of air supply mechanism 6 is arranged at the bottom of the grain storagerefrigeration house; at least one set of air circulation device is arranged in the grain storage refrigeration house and used for pumping the air above the grain surface in the grain storage refrigeration house to the grain bottom for internal circulation; a controller controls operation of the air circulation device according to the received temperature of the a first temperature sensor; or thecontroller controls operation of the air circulation device according to the temperature difference of the first temperature sensor and a second temperature sensor. According to the grain storage method, air is conveyed in winter and used for internal circulation in next summer, the temperature difference of the grain surface and the inside of a grain heap is reduced, moisture condensation cannotoccur to the grain heap, the condition of grain mildewing is avoided accordingly, ageing is not easy to occur to the grain and the good moisture can be kept, and the stored grain quality is improved.

Description

technical field

[0001] The application relates to the field of grain storage, in particular to a grain storage cold storage and a grain storage method. Background technique

[0002] my country is a large grain-producing country, and it is of great significance to do a good job in grain storage, which is related to military supplies and food for the people, as well as national security and social stability. Safe storage of grain is a worldwide problem. According to the survey and statistics of the Food and Agriculture Organization of the United Nations, the annual loss of grain mildew and insect damage in the world is 8% of the grain output. Doing a good job in grain storage depends on three elements: first, there must be good warehouses and supporting facilities; second, there must be a series of relatively advanced storage and storage technologies; third, there must be a set of scientific management methods.

[0003] The storage technology of grain in the related art has f...

Examples

Embodiment Construction

[0059] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with this application. Rather, they are merely examples of means consistent with aspects of the present application as recited in the appended claims.

[0060] figure 1 It is a schematic diagram of the structure of the existing granary. The current method is to directly organize the granary into the granary, supply air to the grain pile through the air supply system 1, and set a ventilation window 3 on the granary above the grain surface 2. Summer grain The temperature between surface 2 and the warehouse ceiling can reach 40-50 degrees. During the grain ...
