摘要
针对传统低温储粮系统效能低、功能单一、精细化管控不足等问题,基于动态隔热阻断理论,创新研发低温储粮靶向通风控温系统.该系统主要包括温度监测、决策控制、驱动执行和远程监控等模块,可实现自主化智慧联动靶向通风控温作业.为验证系统的实用性和有效性,从控温性能、储粮品质等方面进行综合评价.结果表明:在1年试验周期内,全仓均温低于14.2℃,最高粮温低于20℃,水分降低0.2％,脂肪酸值增幅为1.4(KOH/干基)/(mg/100g),相较传统低温储粮控温系统脂肪酸值增幅降低41.7％,且无虫霉发生发展,具有较好的控温性能和品质保持性.系统化解决因储藏局部发热、盲目通风、冷心热皮等问题而造成储粮经济损失,达到高标准低温储粮技术要求.
Abstract
In response to the issues of low efficiency,single functionality,and insufficient precision control in tra-ditional low-temperature grain storage systems,innovatively developd a targeted ventilation and temperature control system for low-temperature grain storage based on the dynamic thermal insulation theory in this study.The system comprises modules for temperature monitoring,decision control,drive execution,and remote monitoring which could schive.To validate the practicality and effectiveness of the system,a comprehensive evaluation was conduc-ted from aspects temperature control performance and grain storage quality.The results indicated that average grain temperature remained below 14.2 ℃,the highest grain temperature was below 20 ℃,moisture content decreased by 0.2％,and the in fatty acid value was increasedly 1.4 mgKOH/100g.Compared with the traditional low-tem-perature grain storage temperature control system,the increase in fatty acid value decreased by 41.7％,and there was no occurrence or development of insect mold.That demonstrated excellent temperature control performance and quality preservation.The system can effectively reduce the economic loss of grain storage and meet the technical re-quirements of high standard low-temperature grain storage.
