高剪切均质机说明书一、摘要均质机主要用于生物技术领域的组织分散、医药领域的样品准备、食品工业的酶处理, ，食品中农药残留以及兽药残留检测以及在制药工业、化妆品工业、油漆工业和石油化工等方面。
均质机采用不锈钢系统，可有效的分离护体样品表面和被包含在内的微生物均一样品，样品装在一次性无菌均质袋中，不与仪器接触，满足快速、结果准确、重复性好的要求。
目前，高剪切均质机主要具备结构紧凑、操作简便、性能稳定可靠、均质效果显著等优点。
为了更好的满足实际工作要求，设计者们还应努力尝试设计出能应对多种介质、实现最大自动化生产的机械设备。
近年来出现各种功能独特的食品机械，在这方面我国与国外先进水平的差距确实存在，但是正在不断缩小。
国内在设计制造特种食品机械的过程中也积累了大量的实际经验。
本次毕业设计是关于高剪切均质机的设计。
首先对高剪切均质机作了简单的概述；接着分析了各部分元件、零件的选型原则及计算方法；然后根据这些设计准则与计算选型方法按照给定参数要求进行选型设计；接着对所选择的各主要零部件进行了校核。
本次设计主要由动力输出电机、联轴器、主轴、筒体、均质轮、端盖、轴承、密封件、紧固件、底座等部件组成。
最后简单的说明了安装与维护。
本次设计代表了设计的一般过程, 难免存在各种纰漏、失误。
权当一次难得的实践过程，希望对今后的选型设计工作有一定的参考和借鉴价值。

二、AbstractHomogeneous machine is mainly used for decentralized organization in the field ofbiotechnology and medical field sample preparation, food industry of enzyme treatment, food pesticide residues and detection of veterinary drug residues as well as in the pharmaceutical industry, cosmetics industry, paint industry, petrochemical industry, etc.. Homogeneous machine uses the stainless steel system, which can effectively separation barrier on the surface of the sample and is contained, microbe homogenous samples, samples were packed indisposable sterile homogeneous bag, and instrument contact meet the requirements of fast, accurate and reproducible.At present, the high shear homogenization machine has the advantages of compact structure,simple operation, stable and reliable performance, and homogeneous effect. In order to better meet the actual work requirements, designers should alsotry to design can deal with a variety of media, to achieve maximum automated production machinery and equipment. In recent years, a variety of features unique food machinery, the gap between China and foreign advanced level do exist in this area, but is shrinking. Domestic design and manufacturing of special food machinery in the process has accumulated a lot of practical experience.This graduation design is about the design of high shear homogeneous machine. First of highshearing homogenizer made brief overview; followed by analysis of the components and parts selection principles and calculation methods; then calculated based on these design criteria and selection method in accordance with the given parameters requires selection of design; then to choose the main parts are checked. This design is mainly composed of the power output of the motor, the shaft coupling, the main shaft, the cylinder body, the homogeneous wheel, end cover, bearings, seals, fasteners, base etc. parts. Finally, simply explain the installation and maintenance.This design represents the general design process, there are many flaws, mistakes. Rightwhen a rare practical process, I hope to have a reference value for future design work..Keywords: high shear homogeneous machine; type selection design; main components;maintenance and maintenance.三、目录一、摘要 . .........................................................................
