High-temperature composting technology generally uses aerobic tank fermentation to make compost, and uses a tank turning machine to ferment and turn the pile. For large yields, a roulette turning machine can be used to ferment and turn. It can also be decomposed by strip-chop fermentation, using a crawler turning machine or walking type turning machine. It can ensure enough high temperature to kill the parasites and roundworm eggs, and kill the vegetative cells of pathogenic bacteria, and kill weed seeds, and consume the energy such as carbohydrates in the materials as much as possible, so as not to be applied to the soil in the future. After the middle, it causes undesirable phenomena such as burning roots and seedlings. At the same time, the high temperature has the conditions to consume as much as possible the crude fiber in the feces and the hydrocarbons in the straw. If the hydrocarbons in the crude fiber and straw are not removed, after applying this fertilizer to the soil in the future, one will burn the roots, and the other is because the carbon-nitrogen ratio of this fertilizer is too high, which will cause a large number of microorganisms to heat up. At the same time, it will compete for the nitrogen source in the soil to balance the carbon-nitrogen ratio, which will result in an unfavorable situation of competing with plants for fertilizer, resulting in slender roots and seedlings. At the same time, the use of a trough-type compost turner for fermentation and aerobic fermentation can ensure rapid fermentation and keep farmers in the middle of the two crops. In a short period of time, the straw decomposing process is fully completed.

Fermentation of organic fertilizers is to use chain plate type compost turning machines that can process livestock and poultry manure and strip-type crawler turning and throwing machines to ferment and decompose. The second is to use aerobic fecal fermentation tank for fermentation, which has a short operating period and high processing efficiency. The heat generated by the fermentation in the fermenter rises, which can preheat the upper layer of feces and facilitate the flow of air and the supply of oxygen. The fermentation tank is divided into multiple layers, and each layer can be fermented. After the manure is put into the fermentation tank, the manure is transferred and turned over by the turning of the flap. The operation is simple, the energy consumption is low, and the floor space is small and the maintenance is convenient. The third is that the flap is provided with vent holes, and the flap is directly left with fine slits. The bottom of each layer of fermentation chamber is arranged with air pipes, which improves the aeration capacity, reduces the energy consumption of the fan, and makes the air distribution more uniform. However, it is difficult for the staff to understand the processing conditions of high-temperature fermentation of livestock and poultry manure from the outside. The livestock and poultry manure after high temperature treatment can be slowly dropped to the top of the transfer truck or on the receiving conveyor to complete the automation of the device, and the waste gas generated during fermentation is processed by a dedicated waste gas processor. The exhaust gas treated by the processor meets the emission requirements. The fecal material that has been fermented and decomposed needs to be thoroughly decomposed in the aging field. The aging field is also called the secondary fermentation plant. The secondary fermentation generally takes 5-7 days, and the secondary fermentation time can also be determined according to the production volume. The maximum time should not exceed 20 days. The white mycelium inside the fermentation product and the aroma of distiller’s grains will be produced at the same time. The secondary fermentation field can also be used as a raw material storage field. The pellets made of raw materials that are not fermented and decomposed are easy to swell after bagging.

Next, the fermented raw materials are crushed, and a special crusher can be used to crush to the granulation requirements, generally 0.5-0.08mm (24-50 mesh). At this time, the crushed raw materials are put into a horizontal mixer for mixing, and humic acid can be added or nitrogen, phosphorus, potassium, reinforcing powder, and organic matter can be added to meet the requirements of the formula and meet the national standards. The agitated raw materials are crushed by a chain pulverizer and then 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 form balls, and the ball formation rate can reach 95%.

At this time, the manufactured particles are sent to the dryer for drying. The length and diameter of the dryer are determined according to the output. The retention time of particles in the dryer is generally about 30-40 minutes. The particles are dispersed in the dryer through the lifting device to fully absorb heat. The heat is generated by the hot blast stove and sent to the dryer through the induced draft fan to dry the particles, suck away the moisture, and enter the dust removal room. After the gas entering the dust removal room is processed, it meets the air emission requirements, and then is discharged into the atmosphere. This meets the requirements of air environmental protection. At the same time, the dried semi-finished product is sent to the cooler for cooling. The feed temperature is generally 60-80 degrees, and the temperature of the cooled material is generally about 30 degrees. Then the cooled semi-finished product is sent to the sieving machine for screening For classification, the particle size of the finished product is between 2.5-5.5, and the finished particles after sieving are sent to the coating machine.

Send the large over-standard particles and small particles into the chain-type powder mill after stirring to be crushed and re-granulated. Color to achieve customer satisfaction, and the coating agent contains certain nutrients to achieve slow-release purpose). The particles sent into the finished product warehouse are weighed and packaged by an automatic weighing and packaging machine. When weighing, they are bagged according to their own set weight. After sealing, the finished organic fertilizer can be sent to the finished product warehouse or shipped out of the factory.
