Paddy quality-guaranteeing storing process

Abstract

The invention discloses a paddy quality-guaranteeing storing process. According to the process, detected temperature and humidity parameters are compared, and according to the precise judgment of ecological conditions in different grain storing ecological regions, barn maintenance structures and targeted grain temperature of different months, real-time automatic control of ventilation devices, refrigeration devices, circulation devices and the like is timely carried out, so that the targeted temperatures of each point and each layer in the grain piles during the whole period of paddy storing are met, and the purposes of quality guaranteeing and loss reduction of paddy storage are achieved. The grain pile volume in the barn is large, so that the temperature inside the grain piles is low insummer, and the surface grain temperature of the grain piles is high. The cold storage performance of the barn is fully utilized in the process, the cooling capacity of the natural environment is utilized for cold storage in winter, and the cooling capacity stored inside the grain piles is utilized for cooling the surface grains in summer, so that the storing process provided by the invention hasthe advantages of energy conservation and uniform grain storage temperature.

Description

technical field [0001] The invention relates to the technical field of grain storage and fresh-keeping, in particular to a rice quality-preserving storage process. Background technique [0002] The cultivation of late indica rice in my country is mainly distributed in the Yangtze River Basin, the southeast coast, and central and southern China. The one-season late rice is harvested at the end of September of the year, and the double-season late rice is harvested in early November of the year. The output of late indica rice in my country is about 100 million tons, accounting for about 50% of the total rice output; late indica rice is mainly used for rations, and the consumption of rations exceeds 80 million tons. Generally, rations need to be stored for a period of time, and the storage time is 2-3 years. Japonica rice is mainly grown in the three northeastern provinces, Jiangsu, Zhejiang, Yunnan and Anhui. The harvest season of japonica rice in northeast my country and late...

Problems solved by technology

[0004] Due to the fact that the intelligence level of storage equipment in my country's grain depots is not high at present, the machine is mainly operated manually, not only the temperature adjustment is not timely, the real-time performance and accuracy are poor, but also the problem of manual operation is labor-intensive.
