Improving particle and nutritional quality: The dual-mode extrusion equipment produces particles with neat shapes, moderate hardness, easy storage and transportation, and can maintain their original state in water for a long time; The secondary spraying process solves the problem of uneven mixing of nutrients in traditional granulation by layering and wrapping auxiliary materials, making the effective ingredients of each fertilizer more balanced and ensuring stable fertilization effect.

Adaptation to special materials and scenarios: The dual drying process can handle difficult to pelletize materials such as silicon calcium potassium magnesium fertilizer, the dual-mode extrusion equipment can process various organic materials such as livestock manure, and the secondary spraying process is suitable for microbial fertilizers with high requirements for microbial activity and nutrient ratio, covering various production needs that cannot be met by single step pelletization.

Retaining the core value of bio fertilizer: Low temperature rise during dual-mode extrusion granulation can avoid high temperature damage to the activity of microorganisms in bio fertilizer; The secondary spraying process will be accompanied by steps such as low-temperature air drying, which can also protect active ingredients such as microbial agents and amino acids, ensuring the core role of biological fertilizers in improving soil and promoting growth and yield increase.
