PAGE  第 PAGE 7 页 摘 要 时代在发展，人类在进步。本设计的目的是为蓝莓汁的生产提供低成本的干燥设备，为蓝莓汁的推广打下坚实的基础，同时也为环保事业做出贡献。 本设计采用如下方案：采用转筒式，直接传热方式，主要靠对流传热，采取并流操作，使用高温烟道气作为载体。由一般异步电动机，圆柱齿轮减速器和齿轮齿圈传动组成动力传动装置。由重油燃烧产生烟道气，石棉做保温层，尾气除尘设备选择旋风分离器。物料进、出传送均采用皮带传输机。密封方式颈向迷宫式密封。 在设计任务给定后，确定了设计所需的基本参数。进行了物料衡算和热量衡算，解决了需要消耗多少干燥介质和热量的问题。依据物料衡算和热量衡算的结果计算并确定了设备的规格参数。对干燥设备作了结构设计的详细计算和必要的强度校核。并选择配套的附属装置，如物料的传输方式选择、热风系统加热方式选择、引风机选型等，更加完善了设计的完整性。 关 键 词：直接传热，转筒式，干燥，蓝莓汁Abstract Era in the development of human progress. The purpose of this design is to provide a low-cost production of blueberry juice drying equipment , and lay a solid foundation for the promotion of blueberry juice , and also to contribute to the cause of environmental protection . This design uses the following programs : the use of tumble , direct heat transfer , mainly by convective heat transfer , adopt and stream operations , using high-temperature flue gas as a carrier. From general induction motor, cylindrical gear reducer and gear ring gear integral power transmission devices. Flue gas generated by the combustion of heavy oil , asbestos insulation done , select the cyclone exhaust removal equipment . Materials into and out of the belt conveyor transfer are used . Neck seals to seal labyrinth . After a given design task , determine the basic parameters required for the design . Conducted a mass balance and heat balance , to solve the need to consume and how much drying medium heat problems. Based on the results of material accountancy and heat balance calculations and to determine the specifications of the device parameters . Detailed calculations made ??for the structural design of drying equipment and the necessary strength check . And select the associated ancillary devices, such as transmission of material selection , hot air heating system mode selection , fan selection , etc. , more sophisticated design integrity. Key Words：Transmit heat directly，cylinder，Dry，Blueberry juice 目 录  TOC \o 1-3 \h \z \u  HYPERLINK \l _Toc389595821 摘 要  P
