Rice is the main food crops in Fujian Province, annual planting area of ??900,000 ha, the annual output of 500 tons or more. Rice drying of the majority of farmers in our province is still taking natural drying method, drying yard smaller venues, the ten dry inefficiency, poor results, easy to pollution, loss. Therefore, the development of grain drying machinery, promotion of grain drying technology, slow down the deterioration of food quality, increase food postpartum economic benefits, to ensure long-term safe storage food has caused all levels of government in the province, agriculture and food departments attach great importance. But in recent years due to the province grain drying machinery to promote the use of cost and the way they operate problems, promote the application of the effect of grain drying is not good enough, grain drying has been very low degree of mechanization. Therefore, how to reduce the cost of drying operation, to explore effective operational mechanism, and actively guide food companies, seed companies, farms, large grain purchase drying machines, creating ripe conditions for the development as soon as possible is a priority. In this paper, the Ministry of Agriculture in Minhou County, Fujian Province, Lianjiang County breadbasket drying projects, promote the use of the cost of using the promotional value of the grain dryer using different operation modes research and analysis and demonstration, hope that the results can be used as the South Depending on the economic situation and the scale of operation, the frame of reference of the scientific and rational selection and promotion of grain drying machinery. The paper is divided into five parts: the first chapter: the background of this paper, on the purpose and significance of research trends and trends. Chapter II: This paper describes the principle of grain drying and drying methods, and the drying process of hot air temperature, the amount of hot air drying speed, slow-Soviet time and grain moisture content on food quality, a brief description of the various drying equipment and focus commonly used in Fujian Province, rice dryer models and performance analysis. Chapter III: analysis of the use of rural grain drying Present Situation and rice dryer features proposed we should vigorously develop the shares, corporate-style, self-, co-, leasing and state of six operating model, and analyzes the breadbasket drying of the main problems and countermeasures. Chapter 4: Introduction to the theory of grain drying costs and cost analysis, Fujian Province, commonly used for a long time Newpro-60, the three of 5HSG-60, three long ACF-40, with three rounds of hair 5HSG 30, three hair 5HSG type -15 temperature cycling dryer the adaptability economic analysis. Chapter 5: This article summarizes relevant conclusions drawn reduce the cost of grain drying method, each of the operating mode for the corresponding models, as well as suitable for promotion in the near future focus.
