With the improvement of grain species, yield enhancement and increase of investment from goverment, there are more and more facilities on large, medium and small grain dryings. It is very critical to choose the high quality, long life, economical and practical, good reliability and high degree dryers. Now, I just use my experience to help you how to choose suitable one according to dryers' different characteristics.
According to the type and quantity of food and grain:
Different varieties of grains can apply into different dryers. Wheat, rice-based food-producing is right for mixed countercurrent dryer. Corn-based areas can use selectable multi-level downstream temperature rapid dryer. Rice producing can be applied with optional smooth reflux, mixed reflux temperature, and a large retarding section dryer. Different food has different drying processes and temperatures, according to the number of grain, you can choose different types of drying process and dryers.
Comprehensive analysis, choose the rational allocation of the dryer:
Dryer model size configuration is based on the local actual situation and the productivity and precipitation magnitude of of the dryer. If we require is to need 3000t corn with 26% moisture, the average ambient temperature is -5 ℃, and the corn can be stored for about 15 days, working 20h everyday, to make the water fall into 14% within 30 days, the better choice is to use the small dryer with the large drying capacity. If you want to dry the concentration of grain producing areas, you can choose large-scale high-temperature, high efficiency drying machine according to the actual situation.
According to local energy resources, to select the drying heat:
You should consider the local energy resources when you choose drying machine to achieve rational use and reduce costs. If it is a coal grain producing area, the heat source shoud be coal, anthracite or coke, its price is economy, but the coal-fired stove is a big consideration. If it is an oil and gas producing area, you can use available light diesel oil, heavy oil or natural gas and propane, but these materials are with high cost.
Take environmental conditions into the consideration
Because of the harvest season is not so clear, as well as the temperature differences between North and South, it is necessary to consider the drying effect and operating costs. If possible, coastal areas should avoid drying grain in the cold and damp weather, or dehydrating effect is poor, low productivity, high cost of drying.In northern region, nearly half of the time is the below 0 ℃, the outside temperature is lower, the desired unit heat consumption is relatively large, the cost is higher.
