1、本科机械毕业设计论文CAD图纸QQ401339828腊肠烘干机摘要本设计论述了研制自动化连续型腊肠烘干机必要性和可行性。腊肠可以分为叶状类腊肠和根茎类腊肠，叶类腊肠表面残存有尘土、有机肥、及残存的化学农药、微生物等，且叶类腊肠本身比较嫩脆，容易折段压溃，而根茎类腊肠表皮强度较好，有的还要求去皮食用，不存在表皮损伤问题。我们针对叶状类类腊肠和根茎类类腊肠这两种腊肠物理性质的不同，分别设计了QX-J型根茎类腊肠烘干机和QX-Y型叶状类腊肠烘干机，并介绍了其工艺流程和整体结构。QXJ型根茎类腊肠烘干机采用滚筒方式烘干，QX-Y型叶状类腊肠烘干机工

2、艺流程为浸泡烘干--喷射烘干--超声波烘干--喷淋烘干--出菜。利用高于20KHZ的超音频电能的超声波，能通过换能器转换成高频机械振荡而传入到烘干液中。超声波在烘干液中疏密地向前辐射，使液体移动，并产生数万计的微小气泡，这些气泡在超声波纵向传播的负压区形成、生产、迅速闭合称为空化现象。在空化现象中气泡闭合时形成超过1000个大气压的瞬时高压，连续不断产生的瞬时高压就像一连串小爆炸不断地轰击物体表面，使物体表面及缝隙中污垢迅速剥落，这种空化侵蚀作用就是超声波烘干的基本原理。关键词：自动化浸泡喷淋超声波烘干水处理29本科机械毕业设计论文CAD图
