The drying principle of organic fertilizer drying equipment is mainly the following:

1. Principle: Indirect heating drying equipment usually uses a hot air furnace to transfer heat to the air inside the dryer, and the hot air then contacts the organic fertilizer, and transfers heat to the organic fertilizer through heat transfer, so that the water in the organic fertilizer evaporates, thereby achieving the purpose of drying.

The heat generated by the hot air furnace is used as a heat source, and the heat is transferred to the air inside the dryer through a pipe. The temperature of the hot air is generally between 50℃-200℃, which is adjusted according to the characteristics of the organic fertilizer and the drying requirements.

2. Features: The drying temperature is relatively low and has little effect on the quality of the organic fertilizer. Since the hot air is indirectly heated by a heat exchanger, the temperature is relatively low, which will not damage the organic matter in the organic fertilizer and can ensure the quality of the organic fertilizer.

The equipment operates stably and has high reliability. The heat source of the indirect heating drying equipment is not in direct contact with the organic fertilizer, which avoids the pollution and damage of the heat source to the organic fertilizer. The equipment operates stably and has high reliability.
