Pig waste disposal

The fermentation cycle for making organic fertilizer from pig manure is short and is usually completed within 7-8 days, which means high production efficiency and the ability to quickly convert pig manure into high-quality organic fertilizer. This rapid conversion process not only saves time but also reduces energy consumption compared to traditional fermentation cycles. By finely controlling parameters such as temperature, humidity and ventilation during the fermentation process, energy utilization efficiency can be maximized and energy waste reduced.

In addition, the quality of organic fertilizer products made from pig manure is stable, which benefits from the full degradation of organic matter and the active role of microorganisms during the fermentation process. Fermented organic fertilizer is rich in nutrients and beneficial microorganisms, which can promote plant growth. It can also help improve soil structure and soil fertility.

Pig waste management

pig manure

Many farmers will face the challenge of pig manure disposal during the process of raising pigs. As the scale of pig farming continues to expand, the treatment of pig manure has become increasingly urgent and complex. The traditional simple composting method can no longer meet the needs of environmental protection and resource utilization. Pig manure contains a large amount of organic matter and nutrients. If not treated properly, it will easily produce odor and pollute the surrounding environment. Therefore, farmers need to find more scientific and effective pig manure treatment methods to achieve the goals of resource utilization and environmentally friendly breeding.

In modern pig farm management, some advanced treatment technologies, such as anaerobic digestion, compost fermentation, organic fertilizer production, etc., are being widely used. Through these technologies, pig manure can be converted into organic fertilizer or bioenergy, and through reasonable recycling, the negative impact of waste on the environment can be reduced. In addition, some new pig manure treatment equipment and systems are also emerging, providing farmers with more choices and possibilities.

Pig manure small organic fertilizer production line

The small pig manure organic fertilizer production line is production equipment designed for farmers or small farms, aiming to solve the problems of pig manure processing and organic fertilizer production. The production line usually includes pig manure pretreatment, fermentation, crushing, granulation, drying and packaging.

First, pig manure is pre-treated to remove impurities and odors, and then enters the fermentation stage, where microorganisms are used to convert organic matter in pig manure into organic fertilizer under controlled temperature, humidity, and ventilation conditions. Then, the fermented organic materials are crushed to make their particles more fine and uniform.

The pig manure high-humidity material organic fertilizer crusher is also called a special crusher for organic fertilizer. This machine has the same crushing effect on fermented organic fertilizer, sludge, biogas residue, coal gangue, municipal waste and other slag. The pig manure high-humidity material organic fertilizer crusher adopts double rotors for upper and lower crushing; there is no screen grate bottom, and there are no strict requirements on the moisture content of the material. It is suitable for materials with a moisture content of 35%-50%, and there is no problem of the screen plate being blocked. There is no problem that the fine powder cannot be discharged in time and is crushed repeatedly.

The fermentation cycle of making organic fertilizer from pig manure is short (7-8 days), the energy consumption is low, and the product quality is stable. The thickness of the pig manure organic fertilizer fermentation material in the tank is 70-90cm, and continuous aerobic fermentation is carried out by natural ventilation and the oxygen provided by the contact between the material and the air when turning over the pile.

Under the transportation of the vertical and horizontal traveling mechanisms, the high-speed rotating rake throws up and scatters the fermentation materials and produces a certain displacement, so that the materials move back in a regular and equal distance in the tank. The fermentation materials are moved from the end of the fermentation tank every day. The finished materials are transported away, and the space vacated at the front of the fermentation tank (one day’s processing capacity) is replenished with new fermentation materials, thus forming a continuous fermentation process.

In the granulation stage, rotary drum granulator is used to compress the crushed organic materials into granules, which not only facilitates storage and transportation, but also improves the utilization rate of fertilizers. Drying equipment then evaporates excess moisture from the pellets, bringing them to a level suitable for packaging and use. Finally, the organic fertilizer is packaged by the packaging machine into bags or bulk, which can be sold directly or used for farmland application.

The qualified granulation rate of this machine is as high as 80-90%, which is suitable for a variety of different formulas. The compressive strength of organic fertilizer is higher than that of discs and drums, and the large ball rate is less than 15%. The uniformity of particle size can be passed according to user requirements. The machine has stepless speed adjustment function. This machine is most suitable for direct granulation of organic fertilizer after fermentation, saving the drying process and greatly reducing manufacturing costs.

When the quantitative packaging scale enters the automatic operation state, the weighing control system opens the feeding door and starts feeding. The feeding device has two-stage feeding modes: fast and slow: When the material weight reaches the fast feeding setting value, fast feeding will be stopped and slow feeding will be maintained; When the material weight reaches the final set value, the feeding door is closed to complete the dynamic weighing process; at this time, the system detects whether the bag clamping device is in a predetermined state. When the packaging bag has been clamped, the system sends a control signal to open the weighing hopper for unloading. The material enters the packaging bag. After the material is discharged, the discharge door of the weighing hopper is automatically closed. After the material is discharged, the bag clamping device is released and the packaging bag automatically falls. After the packaging bag falls, the bag is sewn and transported to the next step. Station.

The small pig manure organic fertilizer production line has the characteristics of easy operation, small footprint, and high production efficiency. It can solve farmers’ needs for pig manure processing and organic fertilizer production, and also provides an environmentally friendly and efficient fertilizer production solution for agricultural production plan.
