Abstract

The invention discloses a house type barn food grain storing method. The house type barn food grain storing method comprises an inner loop current temperature control technology, a fumigation and steaming technology and a nitrogen controlled atmosphere technology, which one of the inner loop current temperature control technology, the fumigation and steaming technology and the nitrogen controlledatmosphere technology is selected for implementation; in the inner loop current temperature control technology, cooling capacity of a cooling core of a food grain pile at the lower part of a barn is pumped out and inputted into space above the top of the food grain pile, and a downgoing type air current is formed in the food grain pile; in the fumigation and steaming technology, fumigation and steaming gas in the space above the top of the food grain pile is pumped out from the upper part of the barn and is charged in the bottom of the food grain pile from a venthole in the lower part of the barn, and an upgoing type air current is formed in the food grain pile; and in the nitrogen controlled atmosphere technology, nitrogen is charged in the space above the top of the food grain pile fromthe upper part of the barn, and then gas is exhausted outwards from the lower part of the barn, so that the concentration of the nitrogen in the food grain pile can reach a nitrogen concentration target value I. According to the house type barn food grain storing method disclosed by the invention, an appropriate storing technology can be flexibly selected according to actual food grain storing situations, so that the food grain storing quality can be effectively improved; and inner loop current temperature control, fumigation and steaming as well as controlled atmosphere storage can be independently operated, so that the food grain storing quality can be guaranteed, besides, consumption of storing energy can be reduced, and the operating cost is low.

Description

technical field [0001] The invention relates to the technical field of grain storage, in particular to a room-type warehouse grain storage method. Background technique [0002] Grain warehousing is the storage and management process of grain from harvest to consumption. Humidity and temperature are the key factors for the safety of grain storage. The traditional granary ventilation system adopts cage ventilation on the ground or floor trough ventilation. The vertical stratification of grain moisture is serious, and the grain piles in the granary tend to form large cold cores and obvious The temperature of the grain at the cold core of the grain pile can be kept below 15°C for a long time, and it can be stored safely for a long time, while the temperature of the grain at the top of the grain pile will reach 25°C-30°C, and the quality of the grain changes quickly and is easily affected. Insect and mildew hazards, accompanied by heat transfer, can cause local heating and agglo...
