Inner circulation low temperature grain storage system and method

Abstract

The invention discloses an internal circulation low-temperature grain storage system and method. The system includes: a granary, at least one vent is provided at the bottom, an electric window is provided on the wall, an electric valve is provided at the vent, one vent and one One end of the root insulation pipe is connected, and the other end of the insulation pipe is connected with a circulation fan, and a ventilation ground cage is provided on the ground of the granary; the ventilation equipment includes at least one centrifugal fan, at least one circulation fan and at least one air conditioner; the grain situation detection unit, It includes a plurality of grain pile temperature sensors and a temperature and humidity sensor in the warehouse; an intelligent ventilation unit, which includes a first server and an intelligent control cabinet, the first server communicates with a small weather station outside the warehouse, and is automatically controlled by the intelligent control cabinet The operation of ventilation equipment and the opening and closing of electric valves. The invention can timely and intelligently regulate when the temperature of the grain pile and the temperature and humidity in the warehouse deviate from the safe grain storage range, which reduces the labor intensity of the warehouse manager and greatly reduces the warehouse management cost.

Description

technical field [0001] The invention relates to the technical field of grain storage. More specifically, the present invention relates to an inner circulation low-temperature grain storage system and method. Background technique [0002] When the grain is stored, if the temperature and humidity exceed the standard, heat and mildew will occur. The traditional method is to use testing equipment such as hygrometers, hair hygrometers, bimetallic measuring meters, and humidity test papers, through manual testing, to ventilate, dehumidify, and cool warehouses that do not meet the temperature and humidity requirements. The method of manual warehouse management, due to the large area and large scale of the grain warehouse, the large number of warehouses and the large capacity, manual inspection is difficult to ensure timely and accurate grasp of the changes in various monitoring indicators during the storage process, which is time-consuming, laborious, and not intelligent enough. ...

AI Technical Summary

Problems solved by technology

[0003] An object of the present invention is to provide an inner circulation low-temperature grain storage system, through the grain detection unit, the intelligent ventilation unit and the grain monitoring and alarm unit, to solve the problem that the existing grain storage system is not intelligent enough. When the temperature and humidity deviate from the safe grain storage range, timely and intelligent control is carried out to reduce the labor intensity of the warehouse keeper
