The centrifuged liquid phase is 100% recovered, with no waste liquid discharge. Power supply requirements are a three-phase five-wire 380V system with an IP65 protection rating. The finished bio-fertilizer contains ≥38% organic matter and has an effective viable bacteria count ≥2×10⁻⁶. 8 CFU / g, moisture content 10%~15%, standard NY525-2021; finished foliar fertilizer amino acid content ≥8.2%, antibacterial rate ≥85%, standard NY / T1974-2010.
