粮堆通风技术,我国早已开展试验.最近一段时间里发展迅速.江浙两省应用这种技术处理储粮已达一百亿斤左右.目前我国许多省、市、自治区正在进行储粮通风降温试验.有的在进行通风干燥降水试验.同时对地上立筒仓和地下喇叭仓亦进行了这一方面的研究探讨.特别是商业部粮食储运局召开了“低温储粮技术座谈会”以后,这项技术发展很快.为了更好的开展粮堆通风技术,提高经济效益和节能效应.对粮堆通风中的几个问题提出一些看法.有些问题尚待继续研究.现分述如下:
Grain piles ventilation technology, our country has already carried out tests.Recent rapid development in recent time.Jiangsu and Zhejiang provinces using this technology has reached 10 billion pounds of grain storage.At present, many provinces, municipalities and autonomous regions are conducting grain ventilation and cooling test Some were conducting the experiment of ventilation and drying precipitation, and the research on the aboveground silos and underground horn storage was also conducted in this respect.Especially the Grain Storage and Transportation Bureau of the Ministry of Commerce convened the “Symposium on Low Temperature Grain Storage Technology” Since then, this technology has developed rapidly in order to better carry out the technology of grain plenum ventilation, improve economic efficiency and energy-saving effect, and put forward some opinions on several issues in grain-plenum ventilation, some of which have yet to be further studied. :
