Parametric Design Of Batch Grain Dryer

China is a big agricultural country,but also a large population,agricultural production in the national economy has an important role.Therefore,food production is of great importance.Increasing food production and ensuring food quality are the basis for ensuring national demand.At the same time,it is also a prerequisite for ensuring the people's food and clothing and maintaining the country's stability.However,as the environment changes and the area under food cultivation decreases,the food problem becomes even more critical.The storage problem can be solved only by continuously increasing the storage capacity and quality of national grain and improving the drying technology of grain.Therefore,attention must be paid to the issue of mechanized drying of food.Drying machinery includes many types,among which the grain dryer is a kind of dryer.It mainly dries and dries grain,grains,etc,so as to achieve the purpose of reducing the moisture content of grain.At present,the types of grain dryers mainly include rice dryers.Corn dryers and so on.With the development of society,the level of agricultural mechanization in China is constantly being raisedIn this paper,the drying process of grain dryer is controlled by the control system.This paper also makes full use of the graphical modeling and simulation tools,and then through computer simulation simulation simulation of the actual system performance.Based on the actual situation of grain drying machine,this paper determines the corresponding control parameters,adopts a new type of variable frequency speed control system to control,and establishes an advanced,stable and efficient overall system.It can realize real time temperature,humidity display control,alarm and other actual functions to further improve the system function to make a certain amount of preparations.In order to complete the design improvement of batch circulating grain dryer,we use CATIA software to model the parts of the dryer in three dimensions and complete the overall assembly work according to the data of the enterprise practice and the related data.
