Notice：
Global grain remind the reasonableness of grain drying machine, reduce unnecessary spending and the rate of fault: drier size configuration is according to the local actual situation, and the drying machine productivity and precipitation rate of the two important indicators of the requirements to comprehensive analysis to determine. If the water content of 3000t is 26%, the average temperature of the environment is 5, the corn can be stored for about 15 days, the daily working 20h, 30 days after drying to 14% of the safe water, can choose to deal with the small, dry capacity of the dryer (converted to 5% per hour, the drying capacity of 12 tons. If the food concentration of producing areas, the amount of food processing in the dry season is large, it can be based on the actual situation to choose a large high temperature, high efficiency, fast food drying machine.
1 according to the local energy resources, select the drying heat source
When choosing grain drying machine, the local energy resources should be considered in order to make rational use and reduce the cost. If there is a food producing areas of coal, heat source to use coal, anthracite or coke is appropriate, its price economy, but a one-time investment in coal fired hot air furnace. Oil fields and natural gas producing areas, the use of light diesel oil, heavy oil, natural gas and propane, as the hot air stove fuel, fuel use of this kind of fuel, but the hot air furnace one-time investment is small. Special seed drying machine is suitable for the application of fuel gas or natural gas. Because of its stable and easy to control, it can ensure the germination rate of the seeds.
2 to determine the service radius of grain drying machine production capacity
Grain drying machine equipped with appropriate should not be small, because in most cases in the harvest season when the rainy season, it is needed to play the role of the dryer, drying capacity, productivity can not solve the problem. National and local reserve library, food concentration of producing areas should be built in large, medium drying machine. The service radius of the fixed dryer should be small, so it is not suitable to reduce the transportation distance, reduce the cost and improve the benefit. Mobile type dryer that can be used for rural grain producing region and the Southern small grain producing areas, the productivity is generally 2 ~ 5t / h is appropriate, too small, users, best use of a machine is applicable not only to in grain and food, also applies to some economic crops, the service radius should be larger, in order to play the role of mobile type grain dryer.
