Biomass hot blast stove drying grain
With the large amount of wheat harvested and listed in 2019, what should we do if the previous coal-fired grain dryer is not environmentally friendly? Biomass hot air stove drying solves the problem, and the environmentally friendly pellet fuel burned by the biomass hot air stove solves the environmental problems.
Why dry wheat? If there is no drying, there is no problem that the environmental protection of the grain dryer is not called drying?
Wheat is one of the main grain crops in my country, and its planting area is spread over North China, East China, Central China, Northwest China, Northeast China and Inner Mongolia. The moisture of the freshly harvested wheat from the field is generally 18 to 25%. If the harvest weather is wet, the moisture* can be as high as 30%; the high moisture is the main reason why the wheat should be dried. As I just said, the moisture of the freshly harvested wheat It is 18-25%, and the ambient temperature after harvest is generally between 15°C and 25°C. According to past experience, wheat is very prone to mildew under the conditions of a temperature of 15 to 25°C and a moisture content of 18-25%. Metamorphosis. Moreover, in some wheat producing areas, due to weather conditions, the harvested wheat has more than 30% moisture. In addition to the internal moisture of the wheat grains, there is also a large amount of free water, which is very likely to cause wheat germination. Therefore, if the moisture of wheat is too high, it is not easy to store, so we have to choose the drying treatment to ensure the quality of wheat.
Coal-fired grain dryer environmental protection is not called dry what to do?
As mentioned above, why wheat should be dried. In recent years, with the continuous improvement of the level of agricultural mechanization in China and the centralized harvesting of wheat mechanization has become the norm, and China’s wheat output has increased year by year, the traditional natural drying can no longer meet the time for wheat processing Requirements, and the weather is changing, the rural labor force is short of machinery, and there are fewer and fewer drying places for grain. Many farmers directly sell wheat with high moisture to the centralized purchase point. This also makes the scientific mechanical dryers widely promoted. popular. Traditional dryers generally use coal as the heat source fuel for drying, but due to environmental issues, coal-fired hot air stoves are not allowed to be applied to the dryer, so many farmers have headaches and do not know what kind of energy to choose. Substituting coal, and the profit of grain drying is low, how much will the cost increase if other energy sources are selected?
To solve the problem that the environmental protection of the grain dryer is not dry, he used a biomass hot air furnace to replace the original coal-fired hot air furnace. A drying unit that dries 90 tons of wheat requires less than 80,000 yuan. Environmental protection drying can be achieved, and there is a subsidy for agricultural machinery in Jiangsu Province. He purchased 2 biomass hot blast stove workers to get a national agricultural machinery subsidy of 40,000 yuan. The orange equipment below is the biomass hot blast stove. The biomass hot blast stove uses advanced Biomass particle combustion technology, based on the use of biomass particle fuel environmental protection features, adopts intelligent plc control technology, which can match different drying processes according to different grains, different environmental conditions, and different needs of users to achieve intelligent drying Adjust. Compared with the coal-fired hot blast stove, there is almost no increase in the drying cost. This is why the user chooses the biomass hot blast stove to replace the coal hot blast stove.
Biomass hot blast stove replaces coal-fired hot blast stove in a large number of grain dryers, which not only solves the environmental protection problem, but also improves the drying efficiency of wheat, and the key cost is almost not increased. Biomass hot blast stove replaces coal hot blast stove, grain drying The problem of machine environmental protection not being dry is solved, effectively avoiding the damage caused by mildew after harvest, so that farmers do not reduce production due to environmental protection problems.
