谷物烘干是农业生产中不可缺少的环节,直接影响农业生产丰产与丰收的关系。以我市为例,全市水田面积达1.9万hm~2,年产粮25万t。由于地处东南沿海,雨量充沛,使得历年来在粮食收获季节,往往会遇到阴雨连绵天气或遭台风频繁侵袭,造成大量的谷物发芽霉变,每年的谷物损失达5％～15％。其次,联合收割机推广应用后,收获作业效率提高,短时间内收获谷物量大,用靠天晾晒的自然 Drying of cereals is an indispensable link in agricultural production and directly affects the relationship between high yield and harvest in agricultural production. Take the city as an example, the paddy field area in the whole city reaches 19,000 hm ~ 2, with an annual output of 250,000 t. Due to its abundant rainfall in the southeast coast, rainy weather and frequent typhoons often occur during the grain harvesting season over the years, resulting in mildew of large amount of cereal grains and annual grain loss of 5% -15%. Secondly, after the combine harvester is popularized and applied, the efficiency of harvesting operation is improved, the amount of grain harvested in a short time is large,
