1、中 文 摘 要 - I - 摘摘 要要 双孢蘑菇的采摘、 储存、 运输过程中的保鲜一般都是采用冷藏方式。 储存和运输环节的冷藏已经有比较成熟的设备， 采摘后到冷库过程的冷 藏也有相应的设备，但由于本人接触较少，对设备构造及原理和应用不 是很了解。为此，我试图将双孢蘑菇进入冷库前应用到的真空预冷技术 应用到毕业设计中，从而形成双孢蘑菇真空预冷装置的设计理念。 本文阐明了果蔬真空预冷装置的原理、组成、特性及优点；给出了 基本设计参数的确定方法及计算公式, 可供专业人员设计参考。将双孢 菇储藏真空预冷技术应用到双孢菇采收的过程中, 提出了蔬菜田间真 空预冷装置的设计理念。 设计以 10000kg/车

2、、 处理量 500kg /次为例, 介 绍了真空预冷装置各主要部件的设计方法。 关键词：双孢蘑菇、真空、预冷装置、设计 英文摘要 II Abstract Agarics picking, storage, transport process is usually adopts refrigeration fresh way. Storage and transport links have been developed comparatively mature equipment, and after being picked to cold storage process of refrig

3、eration equipment, there are corresponding, but because I contact less, on the equipment structure and principle and application is not very understanding Therefore, before agarics getting into refrigerated storage room well attempt to make the vacuum pre-drying cold technology to the process of the

4、 harvest which forming a design idea of agarics vacuum pre-drying cold room. The thesis not only stated the principle and combinations and features and advantages of vegetable vacuum precooling device, but also gave the designable ways and the formulas for calculating the basic parameters, which can be refereed to by designer. Will one pair of vacuum storage precooling technology is applied to one pair in the process of collecting, and put forward the vegetables in the field of vacuum precool
