The Low-Temperature Preservative Drum Granulator is specialized equipment engineered for processing heat-sensitive, oxidation-prone materials containing active components such as biological agents, organic nutrients, and pharmaceutical intermediates. It features a low-speed rotary drum with temperature-controlled jacket and gentle material-lifting system to minimize friction-induced heat generation, ensuring granulation process temperatures remain below 45℃.

• Gentle Material Processing: Soft-edged lifting plates and optimized drum inclination reduce collision and friction, avoiding particle fragmentation and active ingredient inactivation
• Precision Binder Spraying: Atomized moisture-adjustable system ensures uniform binder distribution with minimal dosage, preventing over-wetting and component damage
• Optional Inert Gas Protection: Configurable nitrogen/argon protection system isolates oxygen, preventing oxidation of active materials during granulation
• High Active Component Retention: Gentle processing mode maintains over 90% activity of sensitive ingredients, ensuring product functionality and quality
• Easy Parameter Adjustment: Variable-speed drive with adjustable drum inclination and binder dosage adapts to different heat-sensitive materials and granule size requirements

Specialized in gentle granulation of heat-sensitive & active materials, widely applied in:

• Bio-Fertilizer Industry: Granulation of bio-organic fertilizer containing probiotics, microbial agents, and plant growth regulators
• Biochemical Industry: Granulation of enzyme preparations, microbial catalysts, and bioactive peptide materials
