干燥机设计（全套）2012本科毕业设计 The Softening kettle

Abstract： The tube body is the machine body that the softening kettle. The tube body inside since carry on heat and qualities' deliver and transport the material， the size of the tube body symbolizes the specification and the production ability that the softening kettle. The tube body should have enough of just degree and strength. Must keep the straight line of the stalk line and cut a degree of the noodles in install and revolve. The material of the tube body uses the low metal alloy steel of Q235 steel and commonness generally. Raised to transmit heat the efficiency， developed the potential of the steam well， lower the steam to eliminate Consume; raised the roller to soften the tube wall temperature of a pot of heating row tube， increase the equipments processing quantity， raise the material to soften the efficiency. Should according to the category and dissimilarity with amount of waters that oil anticipate， draw up to soften the temperature; When the oil anticipates to contain the amount of water low， soften the temperature and should correspond a little higher， whereas， should be a little lower. Anticipate the dissimilarity with amount of water according to the oil， can carry on heat smooth wet or heat to the water. Adjust to soften the condition according to the force result. Another important aspect of shaft design is the method of directly connecting one shaft to another. This is accomplished by devices such as rigid and flexible couplings. A coupling is a device for connecting the ends of adjacent shafts. In machine construction， couplings are used to effect a semi permanent connection between adjacent rotating shafts.

前言
油脂与粮食同为人类最基本的生活必需品。油脂制燃术、加工技术、工艺流程、质量检测、包装储藏、生产管理是油脂生产全程中最为关键的环节。
在植物油脂加工过程中，油料在预处理阶段非常关键，国内油厂普遍采用软化步骤和专门的软化装置--滚筒软化干燥机(softening kettle).但是目前-些油厂尤其是中小油厂，对该工艺及设备的计算熟悉程度不足，所以，对此工艺的
