Do you know how to make Rhizobium biofertilizer in a simple and reliable way? The core idea is clear: you first create clean and stable fertilizer pellets, then spray Rhizobium onto the cooled pellets through a coating machine. This physical process protects the bacteria and keeps high activity. To support this workflow, you prepare suitable carriers, granulate them, cool them, and finally apply Rhizobium with a controlled spraying system. With the right equipment setup, you can build a stable and efficient Rhizobium biofertilizer production line.

To make Rhizobium biofertilizer, you must prepare a clean and stable carrier. Many manufacturers use humic acid, torv, compost powder, or well-fermented livestock manure. These materials hold moisture well and protect Rhizobium during storage. You should keep the raw materials low in pathogens and heavy metals because contaminated carriers reduce Rhizobium activity.

You need to crush and screen the carrier materials first. Crushing creates uniform particle size. Screening removes stones, plastic pieces, or wood chips. Etter det, you can adjust moisture to around 30%. This moisture level helps the materials stick together during granulation. Samtidig, a clean, fine carrier improves the survival rate of Rhizobium during the coating stage.

Du kan bruke en Diskgranulator or a double-roller extrusion granulator to shape the carrier into pellets. Disc granulation works well with humic acid or organic matter. Roller compaction granulation makes denser and more uniform pellets. Both machines run at low temperature, so the pellets stay suitable for later Rhizobium coating. Etter granulering, you should place the pellets in a natural drying area or a low-temperature drying room.

Rhizobium is highly sensitive to heat, fuktighet, and mechanical force. The mixing, Granulerende, and drying stages can kill most of the bacteria. Derfor, manufacturers use a post-granulation coating system. This technology sprays Rhizobium onto cooled pellets inside a coating machine. The coating process protects the bacteria and keeps their survival rate high.

Yushunxin equips the coating machine with a precise spraying system. It includes a fine mist nozzle, a peristaltic pump, and a control panel. When pellets roll inside the drum, the nozzle sprays Rhizobium liquid evenly on their surface. The drum runs at a slow and stable speed. This gentle motion protects the bacteria from heat and friction. The system gives you uniform Rhizobium loading and stable biofertilizer quality.

YUSHUNXIN offers a full solution for Rhizobium-based fertilizers. The main machines include:

We design each production line based on your raw materials, plant size, og budsjett.

The cost depends on capacity and equipment configuration. A small 1–5 t/h Rhizobium biofertilizer line price often ranges from $50,000–$100,000. A medium 5-10t/h line may cost $100,000–$150,000. The spraying system usually accounts for a small portion of the investment. You can also upgrade your existing organic fertilizer plant by adding only a coating machine and spraying unit, which reduces cost.
