Are you curious about why you should add bacteria after drying biofertilizer granulation process. This is because high heat during drying and granulation kills beneficial microbes. If you add bacteria before drying, the temperature (60-100°C) destroys most live cells. Your product then fails to meet biofertilizer standards. Post-drying inoculation solves this problem. Le séchoir removes moisture and hardens granules first. Then the cooled, dry material receives the liquid bacteria spray. This low-temperature process keeps the microbes alive and dormant.

Do you know what types of bacteria are typically added after drying biofertilizer granulation process? Nitrogen-fixing bacteria (like Azotobacter and Rhizobium) capture atmospheric nitrogen and convert it into a form that plant roots can absorb. This reduces your need for nitrogen fertilizer.

For best biofertilizer performance, add bacteria only after drying and cooling, when granules feel dry and the outlet temperature stays low enough to protect CFU. This is because adding microbes too early exposes them to heat and moisture, which cuts viability. Your customers will then see weak results in the field. Once conditions are right, choose a form that fits your operation. Liquid inoculant gives quick, even coverage. Powder works well when you control dust and segregation. Suivant, apply bacteria during a clean coating or mixing step. Keep dosing stable and aim for uniform coverage on every granule. A gentle binder or protective revêtement improves adhesion and shelf stability. Enfin, always run a small trial first. Test CFU counts before and after coating to confirm performance. Last but not least, you’d better check your bacteria application timing and coverage as small adjustments here will make a big difference in final biofertilizer quality.
