How to make the heat evenly to dry grain

Source: Time:2019-04-24 08:50:46 views:

Along with our country to vigorously promote agricultural machinery project, grain dryer is enjoyed by more and more small and medium-sized farmers, according to a preliminary survey, using food dryers to dry grain farmers, how to use the grain drying keep heat evenly, below is for everyone to share!

1, grain dryer air brake to control the reasonable ventilation rate. When the ventilation rate is too large, to reduce the air brake in time, ensure that the calcining zone in positive pressure working environment, reduce after the wind, to reduce the moisture content of grain dryer after avoiding the low dry fuel added, with grain dryer temperature returned to normal after rising air brake, make fire before development, and to the grain dryers in ventilation speed up the process of burning fuel, improve grain dryer equipment in the heat. Hours when the ventilation rate, improve the airlock height, make the front of calcining zone in negative pressure environment, the rear part of the material calcined under the environment of positive pressure. At the same time keep the insulation and cooling position into the air, in order to improve the quality of fuel burning and heat exchange efficiency, eliminate the phenomenon of grain dryer grain dryer inside subcooling.


2, calorific value of fuel changes within the grain dryers fuel appropriately added to the grain dryers outside, if the current fuel calorific value is higher than the original fuel combustion heat, reduce fuel additives, increase grain dryers of fuel additives, conversely keep heat balance in grain dryers.

3, want to test the temperature in grain dryers, according to the change trend of temperature in grain dryers, temperature in grain dryers for accurate judgment, and on this basis, the foreign to control the amount of fuel. Ensure that fuel addition, according to the principle of multiple small.

4, to test the temperature in grain dryers according to the change trend of temperature in grain dryers in temperature inside the grain dryers accurate judgment, and based on foreign fuel adding quantity control. Guarantee fuel addition, according to the principle of multiple small, avoid too much or too little fuel add cause temperature rise is not up to standard or incomplete combustion phenomenon.
