In order to make the organic fertilizer can be stored for a long time, the organic fertilizer processing equipment needs to dry the organic fertilizer. So in the fertilizer production process, what methods are generally adopted to dry and dehumidify the organic fertilizer.
1. Mechanical dehydration method: A part of the water is squeezed out by pressurizing the material. The mechanical dehydration method can only remove part of the free moisture in the material, and the combined moisture remains in the material. Therefore, the moisture content of the material after mechanical dehydration is still very high, generally 40-60%. However, mechanical dehydration is the most economical method.
