Grain drying tower
Different drying towers can be used for different grain varieties of the grain drying tower. For example, the grain-producing areas dominated by wheat and rice can choose mixed-flow and mixed-flow drying towers. For example, corn-based production areas can choose multi-stage downstream high-temperature rapid drying tower. For example, in rice-based production areas, you can choose forward and backward flow, mixed countercurrent flow and other low temperature, large slow Su section drying tower. Different grains have different drying processes and different drying temperatures. Depending on the amount of grains in the drying period, different types of drying processes and dryers can also be selected. If there are many varieties of grains, the quantity is small or the grains are scattered and stored, a small batch (circulation) dryer or a small mobile dryer should be selected. If the variety is single, the quantity is large, and the drying period is short, a large continuous drying tower should be used.

The configuration of the size of the grain drying tower is determined by comprehensive analysis and determination according to the local actual conditions and the requirements of the dryer's productivity and precipitation, which are two important indicators. If the requirement is 3000t corn with a moisture content of 26%, and the average ambient temperature is -5 ° C, the corn can be stored for about 15 days, working for 20h every day, and drying after 30 days to a safe water content of 14%. 5t / h small dryer with large drying capacity (converted to 5% water per hour, the drying capacity is 12 tons. Water / hour). If the grain production area is large in the grain production area, the large-scale high-temperature, high-efficiency and fast dryer can be selected according to the actual situation. When choosing a grain drying tower, local energy resources must be considered in order to achieve reasonable utilization and reduce costs. If there is a grain production area in a coal mine, the heat source is preferably coal, anthracite or coke, and its price is economical, but the coal-fired hot blast stove has a large investment at a time. In grain-producing areas with oil fields and natural gas, light diesel oil, heavy oil, natural gas, and propane can be used as hot blast stove fuel. The cost of this type of fuel is high, but the hot blast stove has a small investment at a time. The special seed dryer is suitable for the hot air furnace of fuel oil or natural gas, because its wind temperature is stable and easy to control, which can ensure the germination rate of dried seeds
