Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of grain silo ventilation flow rate control, in particular to a grain silo ventilation flow rate control device. Background Art
[0002] At present, the three methods of controlled atmosphere storage in granaries are relatively rare: reducing the amount of ammonia: adding nitrogen or carbon trioxide. Reducing the oxygen content is to use a deoxygenator or molecular sieve to remove the oxygen in the air in the grain storage warehouse, which can effectively inhibit the survival of various grain storage pests. The cooking quality of rice stored by vacuum method is better than that of rice stored in the air in a conventional way. The cooking time is short, the rice expansion rate is large, and the color is white and loose, which shows that the vacuum storage method can temporarily maintain the original quality of rice. The principle of adding nitrogen or carbon dioxide is basically the same, that is, nitrogen or carbon dioxide produced in the industrial production process is filled into the grain storage warehouse. If technical staff are in such an environment, it is easy to cause hypoxia and suffocation. Therefore, in order to ensure the quality of grain in the granary and maintain a suitable working environment, effective control of the ventilation system becomes crucial. The traditional granary ventilation system usually adjusts the opening and closing of the ventilation pipe to control the wind speed, and requires manual operation, which limits the response speed of the ventilation system and makes it difficult to achieve precise control under changing meteorological and storage conditions.
