The organic fertilizer fermentation equipment is an industrial device specifically designed for the harmless treatment and resource conversion of organic waste.
With “solving fertilizer fermentation pain points, ensuring rapid product quality” as the core goal, our fermentation equipment integrates targeted technologies:
For high-moisture raw materials (livestock manure, food waste, moisture 65%-85%): Adopt “aerobic + dewatering integration” design—equipped with adjustable-speed blades (10-25 rpm) and built-in squeeze dewatering modules, reducing moisture to 50%-60% (optimal for fermentation) without extra equipment;For high-fiber raw materials (crop straw, sawdust, fiber content ≥40%): Match “crushing + microbial inoculation pre-treatment” system—crush straw to 3-5cm and spray compound bacteria agent (containing cellulose-decomposing bacteria), accelerating fiber decomposition by 50%.
Aerobic fermentation system: Deploy “multi-point air supply + temperature feedback” control—maintain 55-65℃ high-temperature zone for 7-10 days, killing 98%+ pathogens (E. coli, salmonella) and weed seeds, complying with GB 18877-2022 Organic Fertilizer standards;Cycle optimization: Shorten fermentation cycle from 30-60 days (natural composting) to 10-20 days (small equipment) / 7-15 days (large continuous lines), improving production efficiency.
Low-temperature stage (after high-temperature sterilization): Automatically adjust temperature to 35-45℃, promoting proliferation of beneficial microbes (nitrogen-fixing bacteria, phosphorus-solubilizing bacteria)—viable bacteria count ≥200 million/g (meeting biological fertilizer GB/T 23473 requirements);Anti-oxidation design: Sealed fermentation chamber with CO₂ retention module, reducing organic matter loss by ≤8% (vs. 15%-20% for open composting).
Integrated system: Small equipment uses “activated carbon + biological filter” (deodorization efficiency ≥95%); large lines match “spray washing + UV photolysis + biofilter” combination—ammonia emission ≤10ppm, hydrogen sulfide ≤1ppm, complying with GB 14554 Odor Pollutant Emission Standards;Leachate recycling: Collect fermentation leachate (rich in nutrients) via bottom diversion trenches, spray back to raw materials as “liquid nutrient supplement”, realizing zero leachate discharge.
Our fermentation equipment covers the core “raw material 腐熟” link of organic/biological fertilizer production lines, matching different raw materials and scales:
Small workshops: Mobile aerobic machines (capacity 5-20 m³/day) for pig/cow manure—suitable for on-farm small-batch production, fermenting 10 tons of manure into 3-4 tons of organic fertilizer in 15 days;Large plants: Continuous fermentation lines (capacity 50-500 m³/day) with automatic feeding/discharging—24/7 production, matching 50,000+ tons/year organic fertilizer lines.
Combined “crushing + horizontal fermentation tank” system—crush wheat/rice straw to 3-5cm, mix with 10%-15% manure (adjusting C/N ratio to 25:1), fermenting into organic fertilizer with organic matter ≥50% in 12 days.
Closed vertical fermentation tanks (with deodorization & dewatering) for kitchen waste/sludge—avoid odor diffusion, kill heavy metal-immobilizing microbes (reducing bioavailable heavy metals by 30%-40%), producing harmless organic fertilizer.
Low-temperature aerobic fermentation tanks (35-45℃ constant temperature)—for microbial agent expansion and mixing with organic carriers (peanut shell powder), ensuring viable bacteria count ≥500 million/g, suitable for high-value biological fertilizer production.
Mini fermentation bins (1-5 m³) for family farms/small workshops (annual output ≤5,000 tons);
Multi-tank parallel fermentation lines (100-500 m³ total capacity) for large enterprises (annual output ≥30,000 tons), supporting continuous material turnover.
As a supplier specialized in fertilizer fermentation, we provide solutions beyond equipment:
A 50,000-ton/year organic fertilizer plant in China used our 槽式 fermentation line—shortened manure fermentation cycle from 25 days to 12 days, organic matter retention rate reached 48%, passing EU organic certification;
A Brazilian livestock farm matched mobile 翻抛 machines—processed 5 tons of cow manure daily, producing 1.8 tons of organic fertilizer, reducing manure pollution and increasing annual income by $60,000;
A U.S. biological fertilizer enterprise adopted our low-temperature fermentation tanks—viable bacteria count stabilized at 600 million/g, meeting EPA organic product standards and expanding to European markets.
