太阳能干燥技术的应用近十年来虽有较大的发展,但多数太阳能干燥器在工业生产中不能持久地应用而被闲置,以致太阳能干燥技术的推广应用未能持续发展,其主要原因是由于至今尚未有太阳能干燥的优化理论的指导,太阳能干燥过程不能优化调控,节能效果不明显.该文以蜜枣为干燥对象进行了太阳能对流干燥情况下的模拟测定,在试验的基础上建立了蜜枣的干燥数学模型,根据此模型以能耗为优化目标求得了蜜枣太阳能对流干燥时的最佳工况,可用于指导蜜枣的实际生产.“,”Although the application of solar drying technology has had a considerable development in the recent ten years, most of the solar driers in industrical production can''t be used for a long time and is lain idle so that the popularization and application of solar drying technology hasn''t been developed sustainably.The main reason is that there''s been no optimization theory of solar drying to guide the development so far,and thus the solar drying process can''t be controlled optimally and the effect of energy...
