Technical Background

With the continuous expansion of global animal husbandry, pig manure treatment has become an urgent environmental issue. Traditional composting methods are inefficient and result in significant nutrient loss. This invention provides an innovative pig manure fermentation technology that converts pig manure into high-quality organic fertilizer through a multi-stage fermentation process.

Preparation Process

Stage 1: Strain Cultivation
Mix biological bacteria, molasses and water, ferment for 40-56 hours to prepare efficient strain fermentation liquid

Stage 2: Primary Fermentation
Mix molasses, corn, water with strain fermentation liquid for fermentation to form primary fermentation material

Stage 3: Secondary Fermentation
Mix pig manure, calcium superphosphate with primary fermentation material, add rice husks or sawdust to adjust texture

Stage 4: Composting and Maturation
Conduct composting fermentation of secondary fermentation material, continue fermentation for 72-96 hours to complete maturation

Product Characteristics and Advantages

• High Organic Matter Content: Over 30% organic matter
• Rich Nutrients: 25-30g NPK per kilogram
• Excellent Physical Properties: Good looseness, easy to apply
• Environmentally Friendly: Effectively solves livestock manure pollution

Global Application Value

This innovative technology provides an economical and effective solution for global livestock waste treatment, integrating it into a complete organic fertilizer production line. The process begins with efficient composting using large wheel compost turner and chain compost turner equipment, followed by advanced granulation through specialized machinery like the double roller press granulator, rotary drum granulator, and various fertilizer granulator systems. This comprehensive approach, utilizing both drum granulation and roller press technologies, not only solves environmental pollution problems but transforms waste into high-quality organic fertilizers. The technology is particularly suitable for large-scale farms, where it can be integrated alongside conventional npk production line operations. The resulting organic fertilizer granulator products help reduce chemical fertilizer dependency, improve soil quality, and make significant contributions to global green agriculture development while creating both economic and environmental benefits.
