我国是农业大国,2014年粮食总产量达6亿多吨。但每年因干燥不及时或处理方法不当造成的粮食霉变、发芽等损失高达5%左右。因此,粮食烘干机械化是我国粮食实现全程机械化、保障粮食安全和减少粮食损失的重要手段,是保障粮食安全“最后一公里”的关键。粮食烘干市场现状从市场对粮食烘干机的使用情况看,干燥技术有气流干燥、流化床干燥、红外干燥等,对于一些较新型的干燥技术如冲击干燥、对撞流干燥、过热干燥、 China is a big agricultural country with a total grain output of over 600 million tons in 2014. However, due to lack of timely drying or improper handling of food caused by mildew, germination and other losses up to 5%. Therefore, the mechanization of grain drying is an important means to realize full mechanization of grain in our country, guarantee food security and reduce food losses, and it is the key to guarantee food security “last mile ”. Grain drying market situation From the market for the use of food drying machine, the drying technology has airflow drying, fluidized bed drying, infrared drying, etc., for some newer drying techniques such as impact drying, collision flow drying, overheating drying ,
