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。

The washing and spraying type machine for vegetable

Abstract This design expounds the necessity and feasibilities to develop the automation continuous type wash, vegetables are divided into leaf form type vegetables and rhizome type vegetable. The surface of the leaf type vegetables and rhizome type vegetable. The surface of the leaf type vegetables remains to have dust, orangic fat. Chomical agriculture chemical and microorganism. And it is fresh and flat, getting easy to be rolled over .The epidermis of the rhizomes type              vegetables intensity better. More of them require to unskin eating. So it does not exist the epidermis problem of damaging, we directed against the differences of physical properties of leaf form type vegetables and rhizome type vegetables to design model QX-J wash for leaf form type vegetables and QX-Y for rhizome type vegetables and introduces their technological process and whole structure. Model QX-J rhizome type vegetables wash machine adopt cylinder. And the processes of the Model QX-Y leaf form type wash machine is immersion washing—spray washing—ultrasonic wave washing—spray washing—bringing the vegetables out.

The height frequently effect ultrasonies which are more than 20 KHZ are translates the mechanical vibrational via the exchanged energy organ and transmitted into the intermedium.Nonstopped vibration of ultrasonic made the liquid moved forward in the intermedium and can give birth to ten thousands of little air bubble. It is called for around-the-clock that the air bubbles form, develop and shut up rapidly in the pressure region of the track of the ultrasonic moving. The opening of the air bubbles form one thousand of air pressure. The lash of the surface of cleaned object continuous and continuous which likes giving birth to dense explosion on the surface of cleaned object made the grease stain fabled off. The fun dametal is the theory of ultrasonic cleaning.
