How To Deal With Chicken Manure In Chicken Farms?

In the past, when the number of chickens was small, we have used chicken manure as farm fertilizer. With the popularization of chemical fertilizers, fewer people will use organic fertilizers. But the number and scale of chicken farms is bigger, so there are a lot of  chicken manure left.  Now it can be said to be a headache problem for all chicken farms.

In the past, some people used chicken dung as a feed for cattle, pigs, etc., but it was also due to the complexity of the process. It is difficult to apply on a large scale; some people also try to dry chicken manure, but drying chicken manure consumes too much energy, the cost is too high, and it is not a sustainable development model.

After people’s long-term practice, making chicken manure into fertilizer is still a relatively feasible method. Although chicken manure is a relatively high-quality organic fertilizer, it cannot be applied directly without fermentation. When chicken manure is applied directly to the soil, it will ferment directly in the soil, and the heat generated during fermentation will affect crops. The growth of fruit seedlings will burn the roots of crops, which is called root burning.

Therefore, chicken manure fermentation is necessary. It is divided into traditional fermentation and microbial rapid fermentation.

1.The traditional fermentation
Traditional fermentation takes a long time, generally 1 to 3 months. In addition, the surrounding stench is unpleasant, mosquitoes and flies breed in large numbers, and the environmental pollution is very serious. When the chicken manure is wet, it needs to be supplemented, and more labor is required. In the fermentation process, it is necessary to use a raking machine to turn the rakes, which is a relatively primitive treatment method.
Although the equipment investment of traditional fermentation is relatively low, the cost of using traditional fermentation to process 1 ton of chicken manure is also relatively high under the current high labor costs, and traditional fermentation will be eliminated in the future.

2. Rapid microbial fermentation
Microbial rapid fermentation is to decompose chicken waste complex organic matter into simple organic matter, and also decompose organic matter into more complex organic matter. The organic matter is continuously degraded and decomposed until it is decomposed into organic fertilizer that can be used by the land. The mineralization of organic matter provides nutrients for the organisms. , produce more carbon dioxide, water and other nutrients, the decomposition speed is accelerated, and it is completely and releases a lot of heat. Therefore, the fermentation speed is very fast. Generally, it only takes about 20 days to change from chicken manure to organic fertilizer. SX can provide professional chicken manure composting system for you.

The principle of rapid microbial fermentation for chicken manure

The biomass reproduces rapidly and decomposes rapidly at a suitable temperature and in a very suitable environment. Generally in the range of 45 to 70 degrees, the generation wave of microbial growth is very fast. Kill bacteria and harmful substances in feces. SX can provide compost machine for chicken droppings to keep temperature at the required level. In a relatively closed small environment, microorganisms can continue to ferment, and chicken manure can be quickly converted into organic fertilizer only through normal feeding, production and output processes.

The chicken manure treated by the rapid fermentation of microorganisms has no odor, and the water content is only about 30%. Moreover, the rapid fermentation of microorganisms can completely treat the harmful gases and then discharge them, and there is no point in polluting the environment. Using the method of rapid fermentation of microorganisms can improve the breeding environment and improve the production efficiency.

The Effect of Organic Fertilizer Turning Machine Equipment in Compost Production

According to many years of experience in the price of organic fertilizer granulator manufacturers, its working principle is mainly through the use of diesel engine as the power source, and then through the power transmission to drive the power, and then use the machete to rotate the material, which is controlled by the technician The working process of the organic fertilizer turning machine. And its own functional effects have the following points:

Self-propelled compost turner in small scale organic fertilizer production

① Realize the special requirements of the composting process, such as crushing the raw materials, giving the raw materials a certain shape or realizing the quantitative shift of the raw materials, etc.

② Adjust the moisture content of the raw material pile, the suitable moisture content of the raw material fermentation is around 55%, and the moisture standard of the finished organic fertilizer is below 20%. During fermentation, biochemical reactions will generate new water, and the consumption of raw materials by microorganisms will also cause the water to lose its carrier and be freed. Therefore, with the fertilizer production process, the water is reduced in time, in addition to the evaporation formed by heat conduction, the compost turning machine turns the raw materials to form a forced vapor emission.

③Improve the permeability of the raw material pile, the turning system can process the materials into small agglomerates, so that the thick and dense raw material pile becomes fluffy and elastic, forming a suitable porosity.

④ Adjust the temperature of the raw material pile. During the operation of the organic fertilizer turning machine, the raw material pellets are fully contacted and mixed with the air, and a large amount of fresh air can be conserved in the pile, which helps aerobic organisms to actively generate fermentation heat and increase the pile temperature. The temperature is high, and the supplement of fresh air can reduce the temperature of the stack. Form an alternating state of medium temperature-high temperature-medium temperature-high temperature, and various beneficial microorganisms grow and multiply in the temperature range that they are adapted to.

⑤ Stirring function in raw material conditioning. In fertilizer production, some auxiliary materials must be added in order to adjust the carbon to nitrogen ratio, pH, and water content of the raw materials. The main raw materials and various auxiliary materials that are roughly piled together in proportion can be mixed evenly by the compost turning machine to achieve the purpose of quenching and tempering.

Introduction to the Steps and Precautions of Organic Fertilizer Production

  1. Mixing of raw materials: the main material is livestock manure, the ingredients (straw, waste tobacco, planting and processing waste, etc.) are crushed, organic and biological bacterial fertilizers are added, and some phosphate rock powder, potassium ore powder, and phosphate rock can be appropriately added Try to purchase medium-grade phosphate rock (total phosphorus content> 18%). The amount of phosphate rock powder added to the organic fertilizer raw materials needs to consider the pH of the raw materials. More phosphate rock powder can be added to the weakly acidic raw materials, and natural potassium magnesium sulfate fertilizers should be less added to the neutral and slightly alkaline raw materials to adjust the nutrients and carbon of the materials. Nitrogen ratio, carbon to phosphorus ratio, pH value, etc. After treatment, the moisture content of the raw materials is controlled at 60%-65%, and the C/N ratio is 20-30. The production of bio-organic fertilizer needs to add beneficial bacteria and functional bacteria, and it needs to be added when the temperature of the material is less than 40 degrees after the high temperature period of fermentation. The paddle-type compost turning machine can control the materials in the tank in sections, which is convenient for operation, and makes full use of the equipment’s ingredient mixing function, fermentation mixing function, and mixing and drying function to simplify the production process. This process is designed as an integrated workshop for ingredient mixing, fermentation, aging (decomposition), and drying to reduce multiple handling of materials.

Note: In the composition of raw materials before composting, the carbon-nitrogen ratio and moisture of the raw materials are mainly considered, followed by particle size and pH: the reasonable range of carbon-nitrogen ratio: 20:1-40:1, the best range: 25:1- 30:1; reasonable range of moisture content: 40%-65%, optimal range: 50%-60%; reasonable range of particle size: 0.32cm-1.27cm, depending on materials, piles and weather; reasonable pH Range: 5.5-9.0, best range: 6.5-8.0.

  1. Fermentation: Fermentation of organic fertilizer raw materials adopts aerobic fermentation process, adopts trough type fermentation turning machine, and blades (rotating tooth type, positive and reverse) to cut and throw materials, which can make organic materials move backward during turning. Each turn moves backward about 2.2 meters. The turning and throwing machine has a mixing function and can be used as a mixer. During the batching, the layered materials can be mixed evenly and then enter the fermentation area (or fermentation period), which can greatly save the investment in raw material pre-mixing equipment and material loading and unloading transportation and pre-mixing work Mix the broiler manure, cassava residue and 0.15% organic material decomposing agent as evenly as possible, stack 60-80 cm high stacks, turn the stacks once every 2-3 days with a turning machine, and control the temperature during fermentation. Below 70°C, the odorless effect is generally achieved in about 20 days, that is, the fermentation is completely decomposed.

Note: During the composting process, the temperature change is mainly controlled. The complete composting process consists of four stages: low temperature, medium temperature, high temperature and cooling. The compost temperature is generally maintained at 50-60°C, and can reach 70-80°C at the highest point. The process of gradually increasing the temperature of the compost is a process of harmless composting (the temperature of the compost is maintained between 45℃-65℃ for 10 days, and pathogenic bacteria, insect eggs and grass seeds can be killed). When the compost temperature rises above 60℃, keep it for 48 hours to start turning the pile, but when the compost temperature rises above 70℃, turn the pile immediately. Make sure to turn the pile evenly and thoroughly. Try to turn the bottom material to the middle and upper part to fully decompose. The frequency of turning depends on the maturity of the organic fertilizer. The pH is controlled in the fertilizer. In the initial stage of composting, organic acid is generated due to the decomposition of organic matter. decline. At this time, if the acidity is too high (pH<5.3), lime or plant ash can be added at 2%-3% of the weight of the raw materials to neutralize the acidity, destroy the wax on the surface of the organic materials and accelerate the fermentation; in the later stage of composting, due to the accumulation of ammonia, the pH It will gradually increase. When the pH is greater than 8.5, fresh green manure, grass, etc. can be added to decompose and regenerate organic acids and lower the pH.

  1. Air-drying and sieving: transport the fermented raw materials to the outdoor drying yard, and after natural drying, ensure that the water content is below 20%, that is, the air-drying is completed, and the air-dried raw materials are crushed through a crusher and then passed through the screen. Sieve to remove impurities.

Note: It is recommended to properly carry out the secondary fermentation in the post-processing of the compost (before air-drying), especially for the raw materials with a large proportion of livestock and poultry manure in the primary fermentation, so as to prevent the finished fertilizer from being applied to the soil and rapid propagation in the secondary fermentation The microorganisms compete for oxygen with the roots of vegetables, resulting in the phenomenon of burning roots and seedlings.

  1. Inspection and packaging: After the crushed and sieved organic raw materials are inspected (sent for external inspection), they are directly quantitatively packaged, which is the powdery finished organic fertilizer. Granulation by the organic fertilizer granulator is the granular finished organic fertilizer.

Note: Before sending for external inspection, judge whether the finished fertilizer is completely decomposed by the color and smell. The completely decomposed organic finished fertilizer can be applied for external inspection. The incompletely decomposed finished fertilizer needs post-processing (or secondary fermentation). The finished fertilizer that has passed the external inspection can be directly bagged or pelletized and then bagged. The finished fertilizer that does not meet the required nutrient content in the external inspection result needs to be returned to the composting workshop, and high-nutrient content raw materials are added to compost and ferment again.
