我国从五十年代后期就开始了谷物干燥机的研制。近年来干燥机的研制工作得到了有关部门的重视和支持。据初步统计,全国农机系统已有八种干燥机定型(见表),少数机型已逐步推广使用。从目前研制的机型来看,有简易固定床式通风干燥设备、低温循环干燥仓及其设备、流化斜槽干燥机、立筒气流式干燥机、滚筒式干燥机、塔式干燥机、远红外线干燥机和高频干燥机等。在燃料方面,除了用柴油和煤外,还有沼气、太阳能以及利用稻糠煤气、柴油机废热等。上述机型中,比较成熟的有简易固定床式通风干燥设备和流化斜槽干燥机。
Since the late 1950s, China started the research and development of grain dryer. In recent years, the development of dryer has been the relevant departments of attention and support. According to preliminary statistics, there are eight kinds of dryer stereotypes in the national agricultural machinery system (see table), and a few models have been gradually promoted and used. From the current model developed point of view, there are simple fixed bed ventilation and drying equipment, low temperature circulation drying chamber and its equipment, fluidized chute dryer, vertical air dryer, drum dryer, tower dryer, Far-infrared dryer and high-frequency dryer. In terms of fuel, in addition to diesel and coal, there are biogas, solar energy and the use of rice bran gas, diesel engine waste heat and so on. Of the above models, the more mature are simple fixed bed ventilation drying equipment and fluidized chute dryer.
