摘要
在本次设计中,我采用的是通过传送带将饼干运输通过隧道炉,再通过加热完成烘焙的目的。隧道炉是通过热的传导、对流、辐射完成食品烘烤的隧道式机械设备。隧道内有一条连续运转的输送系统。食品烤制时,食品通过输送链板、钢带或网带与电热元件或直燃燃烧棒之间产生相对运动。从而完成均匀烘烤和输送的工作。这类烤炉可连续生产,生产效率高,节省人力,烘烤品质稳定。该隧道炉主要用于工业化生产的食品企业,以大批量连续或间歇烘烤为特征。
该设计包含了隧道炉的传送装置结构设计,隧道炉的结构设计,以及加热元件的设计。其中在传送结构设计这方面包含了电动机设计、减速器设计及传送带的整体结构设计。本设计《饼干生产线—烘焙机设计》非常适合作为机械专业大学四年的一个总结。因为其中涉及了机械设计的多个方面,并且与生活实际非常贴合,能充分体现这门专业的内涵与作用。
该有图7幅,表3个,参考文献25篇。
关键词:隧道炉;烘烤;传送带;加热元件;减速器;轴。

nology) 烘焙,也就是我们经常说的烘烤,是指生产物(在这里为饼干)通过加热的方式在燃点之下使得物料达到脱水的目的。对于很多国际加入了WTO,烘焙技术的发展对这些国家(尤其是农业和食品行业)有十分重要的意义。通烘焙食品在人类历史上的厨房工艺中占有着很重要的位置,并且在他拥有重要位置的同时,烘焙技术还成为了一种文化的象征。现代人所食用的食品要具有四个不同的功能:在营养上满足人体需求,在口感上满足人的嗜好,在生理上使得人类达到身体吸收,在文化上彰显国家特色和丰富剧名的日常生活。在历史上,食品也中占有者非常打的比重,即便是在文化交流的方面,食品也有着不容小觑的地位。实际上在人类的社交历史中,食品与政治、经济还有文化都有着密切的关系。无论关系是大是小,譬如国家之间的来往,朋友们之间聚在一起的聚会、朋友过生日时候大家纪念,都无法说可以缺少上述的食品文化的参与。烘焙是面包类的食品饼干类的食品、还要蛋糕类的食品在从制作到食用的过程中绝对不可以缺少的步骤,饼干的主要原材料之一是面粉,而面粉中最多的成分是淀粉,淀粉在受热时会发生煳化,高温会使得面粉内的原有分子结构被破坏,蛋白质的结构被破坏。但是这样可以使得面粉制品,例如面包和饼干从原来的不可食用,变得符合食用标准。通过控制加热的时间,可以在一定程度上及控制分子的破坏程度,这样子可以使得食物的口感变得不一样。在外国国家(尤其是欧美国家),人们经常
