摘  要

玉米作为我国主要额粮食产物，一直以来在食品、保健、养殖等方面有着大量的需求。玉米经粗加工去皮碾压可作为养殖饲料来源，其中猪饲料玉米消费量约占饲料玉米总消费量的半壁江山。另外，玉米含有丰富的蛋白质、脂肪、维生素和各类的膳食纤维等，可满足人类每天的大部分营养摄入。随着经济发展和人民生活水平不断提高，对食品质量的要求也变高，以往的手工或机器粗加工无法满足需求，因此研究一款新的玉米磨面设备是玉米加工产业的前景所趋。

玉米磨面机的工作流程大致为：喂料、脱皮、碾磨、面粉与麸皮的分离。在加工过程中磨辊是控制玉米面粉粗细程度的关键，磨辊的间隙调整精度高，使得面粉加工更为精细。因此对磨辊的设计与布置尤为重要，通过对各种因素的分析，设计出合理的磨辊及整套设备可提高磨面机生产效率与质量，提高生产效益，节能绿色环保，对国内玉米磨面机的自动化、精细化有着深远意义。

本论文主要以计算设计校核为主，工程二维制图与三维建模为辅，全面论述了玉米磨面机的设计流程与成果。

ABSTRACT

As the main grain product in China, corn has always had a large demand in food, health care, and breeding.Corn can be used as a source of feed for breeding after rough processing, peeling and rolling, of which the consumption of pig feed corn accounts for about half of the total consumption of feed corn.In addition, corn is rich in protein, fat, vitamins and various types of dietary fiber, which can meet most of the daily nutritional intake of human beings.With the continuous improvement of economic development and people's living standards, the requirements for food quality have become higher, and the previous manual or machine rough processing can not meet the demand, so the research of a new corn flour grinding equipment is the prospect of the corn processing industry.

The workflow of a corn flour mill is roughly as follows: feeding, peeling, milling, and separating flour from bran.In the processing process, the grinding roller is the key to control the thickness of corn flour, and the gap adjustment accuracy of the grinding roller is high, which makes the flour processing more fine.Therefore, the design and arrangement of the grinding roller is particularly important, through the analysis of various factors, the design of a reasonable grinding roller and a complete set of equipment can improve the production efficiency and quality of the grinding machine, improve the production efficiency, energy saving, green environmental protection, and have far-reaching significance for the automation and refinement of the domestic corn grinding machine.

This paper mainly focuses on computational design verification, supplemented by engineering two-dimensional drawing and three-dimensional modeling, and comprehensively discusses the design process and results of corn flour grinder.
