A biofertilizer production unit is a complete production line designed to manufacture microbial/bio-organic fertilizer. It processes raw materials through steps such as crushing, cribado, automatic batching and mixing, granulación, low-temperature drying/cooling, and weighing & embalaje, producing either powder or uniform granules. Throughout the process, temperature and moisture are carefully controlled to protect microbial viability and ensure consistent product quality.

What’s the technology of a biofertilizer production unit?

A biofertilizer line starts with a wheel loader feeder that delivers materials to a crusher to break lumps, then a drum screen removes oversize. The batching system doses each ingredient by formula. Control material temperature (target ≤35°C); avoid feeding hot fermented piles.

In the wet process, a granulator forms pellets, a rounding machine improves shape, then a dryer and cooler control moisture and temperature; cool pellets to ≤30–35°C, then re-inoculate during coating before bagging (drying heat reduces viable cells). Dust collection, cribado, revestimiento, bagging, and palletizing finish the product. In the dry process, a mixer blends materials, a double-roller extruder granulates without drying, then screening and packing complete the line; if extrusion warms pellets above ~40°C, cool and add bacterias after screening/coating before packing.

Choose the suitable biofertilizer granulator from two aspects: your raw material and product target

Are you troubled with how to choose the suitable fertilizer granulator? When you choose a bio-organic fertilizer granulator, start from your raw material and product target. If your composted manure has higher moisture and strong stickiness, pick a wet granulation machine such as a rotary drum churning granulator or rotary drum granulator. It handles feedstock fluctuations well, delivers high throughput, and makes rounder granules, but you usually need to add drying, enfriamiento, cribado, and recycle loops. If you need to protect living microbes, control drying temperature or apply bacteria like Bacillus megaterium by spraying after cooling.

And if you want low-temperature forming and stronger fertilizer pellets, choose extrusion (flat die). It makes dense, durable fertilizer granules and reduces drying load, but it requires cleaner feedstock and routine die/roller maintenance. For a round appearance, you can add an organic fertilizer polishing machine after extrusion. And if you want low-temperature forming and stronger fertilizer pellets, choose extrusion (flat die).

What equipment is included in a biofertilizer production line?

Are you looking for the right equipment configuration for a biofertilizer production line? You can choose a wet process line or a dry process line based on raw material moisture, granule strength, and energy cost.

Wet line

For wet biofertilizer granulation line, the equipment flows as follows: wheel loader feeder → vertical crusher → rotary drum screening machine → dynamic automatic batching system → a rotary drum granulator / a pan (disc) granulator) → organic fertilizer rounding machine → secador rotatorio → rotary cooler → cyclone dust collector → rotary drum screening machine → coating machine → single-bucket packing machine → palletizer.

Dry line

For dry biofertilizer granulation line, the equipment flows as follows: wheel loader feeder → vertical crusher → rotary drum screening machine → dynamic batching system → horizontal mixer → double-roller extrusion granulator → screening machine → packing machine. In this line, the loader feeder, crusher, and drum screen prepare materials while the dynamic batching system ensures accuracy. A horizontal mixer blends everything evenly, then a double-roller extrusion granulator makes granules without drying. Finalmente, a screen separates qualified granules and a packing machine bags the final biofertilizer product.

What’s the price range for a biofertilizer production line?

Would you like to know how much it costs to set up a biofertilizer production line? The cost of a biofertilizer granulation production line mainly depends on the required capacity. Based on our standard configuration and 6,000 operating hours per year (300 days × 20 horas), the estimated of a wet granulation line is: 1 t/h: Dólar estadounidense 110000; 2 t/h: 110000; 3 t/h: Dólar estadounidense 140000; 5 t/h: Dólar estadounidense 190000; 10 t/h: Dólar estadounidense 360000; 20 t/h: Dólar estadounidense 550000. And the estimated of a dry granulation line is: 1 t/h: Dólar estadounidense 60700; 2 t/h: Dólar estadounidense 60700; 3 t/h: Dólar estadounidense 77200; 5 t/h: Dólar estadounidense 104800; 10 t/h: Dólar estadounidense 209500; 20 t/h: Dólar estadounidense 419000. Final pricing may vary with raw material moisture, required granule size, nivel de automatización, recolección de polvo, and auxiliaries (crusher, mixer, secadora, cooler, cribado, coating and packing). If you want to know the exact price, please share your required production capacity and material specifications.
