The current pig farming industry continues to expand its breeding scale, resulting in a large number of pig manure treatment problems, which have become the main challenges faced by many farms. The pig manure organic fertilizer production line can convert this difficult to treat pig manure into organic fertilizers that can nourish the soil, providing a practical and effective solution for the treatment of manure in breeding farms.

The core link of the pig manure organic fertilizer production line is the collection and pretreatment of pig manure. The pig manure produced by pig farms every day is collected in a centralized manner, and these raw pig manure contain high levels of moisture and various impurities. The staff will first use solid-liquid separation equipment to remove most of the water from it, and then screen the solid pig manure to remove impurities such as stones and fragments, ensuring that the processed pig manure meets the standards for subsequent processing.

The pre treated pig manure will enter the crucial fermentation stage in the production line. The widely used trough fermentation process currently involves stacking pig manure in specialized fermentation tanks and regularly turning the pile with the help of a turner. The flipping process can allow pig manure to fully contact with the air, creating favorable conditions for the growth of aerobic microorganisms. After these microorganisms multiply in large numbers, they will decompose the organic matter in pig manure and release heat, maintaining the composting temperature between 50 ℃ and 70 ℃. This process not only accelerates the maturation rate of pig manure, but also kills harmful bacteria and parasite eggs, while effectively removing odors. After a period of fermentation, pig manure will be transformed into stable humus.

After fermentation, the material needs to be crushed and refined for easy mixing with various additives in the future. When operating, first use a specialized crusher to crush the material to the appropriate particle size, and then feed it into the mixing equipment. According to the preset fertilizer formula, nitrogen, phosphorus, potassium and other nutrients, as well as beneficial microbial agents, are added to the equipment to lay the foundation for producing qualified organic fertilizers.

Overall, the pig manure organic fertilizer production line has successfully solved the problem of manure treatment in the pig farming industry and achieved the resource recycling of breeding waste. With the continuous deepening of environmental protection concepts in various industries, such production lines will be more widely promoted and applied in the future.
