How to ferment animal manure into organic fertilizer? The livestock industry in rural areas of our country has developed rapidly, with its output value accounting for 34% of the total agricultural output. With the increase in the number of livestock and poultry, the amount of livestock and poultry manure produced has also increased rapidly.

High temperature composting technology generally uses aerobic tank fermentation to produce compost, and uses a tank type turning machine for fermentation and turning. For high yields, an impeller turning machine can be used for fermentation and turning. It can also be fermented and decomposed using a chopping method, and fermented, thrown, and decomposed using a crawler or walking stacker. It can ensure the generation of sufficient high temperature, kill parasites and roundworm eggs, kill bacterial nutrient cells, kill weed seeds, and try to consume energy such as carbohydrates in the material to avoid adverse phenomena such as root burning and seedling burning when applied to the soil in the future. At the same time, high temperature is necessary to consume as much crude fiber and hydrocarbons in feces and straw as possible. If the hydrocarbons in crude fiber and straw are not removed, when this fertilizer is applied to the soil in the future, it will burn the roots, and because the carbon nitrogen ratio of this fertilizer is too high, it will cause microorganisms to generate a large amount of heat and compete for nitrogen sources in the soil to balance the carbon nitrogen ratio. This will create a bad situation of competing with plants for fertilizer. Causing plant roots and seedlings to be thin and weak; At the same time, using a trough type turning machine for fermentation and turning, an impeller turning machine for fermentation and turning, and using a track type turning machine and a walking type turning machine for aerobic fermentation can ensure rapid fermentation and allow farmers to fully complete the straw maturation process in a short period of time between two crops.

One is the chain plate flipping equipment and the strip chopping crawler flipping machine that can handle livestock and poultry manure for fermentation and composting.

The second method is to use aerobic fecal fermentation tanks for fermentation, which have a short operating cycle and high processing efficiency. The heat generated by fermentation in the tank rises, which can preheat the upper layer of feces and facilitate air flow and oxygen supply. The fermentation tank is divided into multiple layers, each of which can be fermented. After the feces are put into the fermentation tank, they are transferred and flipped by the rotation of the flipping plate. The operation is simple, the energy consumption is low, and it occupies a small area and is easy to maintain.

The third is that there are ventilation holes on the flip board, which leave fine seams directly on the flip board. Cloth pipes are arranged at the bottom of each fermentation chamber to improve ventilation capacity, reduce fan energy consumption, and make gas distribution more uniform. However, it is difficult for staff to understand the treatment of high-temperature fermentation of livestock and poultry manure in the farm from the outside. It can make the livestock and poultry manure slowly fall onto the top of the transfer truck or the feeding conveyor after high-temperature treatment, completing the automation of the device, and the waste gas generated during fermentation is treated by a dedicated waste gas processor. The exhaust gas processed by the processor meets the emission requirements.

Next, the fermented raw materials can be crushed using a specialized grinder until they meet the granulation requirements, usually between 0.5-0.08mm (24-50 mesh). At this point, the crushed raw materials are mixed in a horizontal mixer, and humic acid can be added or supplemented with nitrogen, phosphorus, potassium, reinforcing powder, and organic matter to meet the formula requirements and standards. The mixed raw materials are crushed by a chain pulverizer and sent to an organic fertilizer granulator for granulation. During granulation, the angle of the granulator and the pressure of the water supply can be adjusted according to the required particle size to achieve a balling rate of 95%. At this point, the pre made particles are sent to a dryer for drying. The length and diameter of the dryer are determined by the production volume. The particles are usually stored in the dryer for about 30-40 minutes. The particles are dispersed in the dryer through a lifting device to fully absorb heat. The heat is generated by a hot air stove and sent to the dryer through an induced draft fan to dry the particles, absorb the moisture, and enter the dust removal chamber. The gas entering the dust removal chamber is treated to meet air emission requirements and then discharged into the atmosphere to meet air environmental protection requirements. At the same time, the dried semi-finished products are sent to a cooling machine for cooling, with a feed temperature of generally 60-80 degrees Celsius. After cooling, the material temperature is generally around 30 degrees Celsius. The semi-finished products are sent to the screening machine for screening and grading, and the particle size of the finished products is between 2.5-5.5, Send the screened finished particles into the coating machine.

Send large and small particles into the stirred chain pulverizer for crushing and re granulation. The finished particles sent to the coating machine are coated and then sent to the finished product warehouse (the coating machine has various colors to achieve customer satisfaction in appearance, and the coating agent contains a certain amount of nutrients to achieve sustained release). The particles sent into the finished product warehouse are weighed and packaged by an automatic weighing and packaging machine. During weighing, they are bagged according to their own set weight and sealed to obtain finished organic fertilizer, which can be stored in the finished product warehouse or transported out of the factory by truck.
