For the dryer of the organic fertilizer production line, it is very important to choose the right heat source.
Air energy heat source: Use high-temperature refrigerant to circulate and do work, absorb energy from the air through the heat exchanger and directly output high-temperature hot air. It has the characteristics of high efficiency and energy saving, and the unit system works without pollution and zero emission, which meets the environmental standards.
Natural gas heat source: Use natural gas or diesel as the heat source, and complete the heat exchange in the hot air furnace body through the burner to generate hot air to enter the drying room to heat and dehydrate the materials. The advantage of this method is that the combustion efficiency is high and the heat generated is large, which can meet the needs of large-scale production.

Biomass heat source: Use biomass pellet fuel as the heat source, and after full combustion, it is converted into clean hot air through the heat exchange device and input into the drying room for recycling. Biomass pellet fuel has a wide range of sources, such as wood chips, straw, etc., and is renewable. The advantages of this method are low operating cost, good environmental protection, and sustainable resources.
Steam heat source: steam is used as the heat medium, and the steam heat exchanger is used to convert steam into heat. Under the action of the fan, hot air is formed to dehydrate and dry the material in the drying room by heat convection. The advantage of this method is that the steam has good thermal conductivity, uniform heating, and a relatively stable supply of heat source.
In summary, the choice of heat source for the dryer of the organic fertilizer production line needs to be comprehensively considered according to the actual situation.
