We all know that unfermented animal manure and organic waste, like livestock and poultry dung, household garbage, agricultural waste can be used directly, because it will harm the soil and crops. If the organic raw material is not fermented fully, it will has the second fermentation in the soil, causing the phenomenon of buring seedings due to the high temperature. Compost fermentation in the soil competes for oxygen with plants, which affects the respiration of plant roots and causes diseases. Ammonia gas in compost attracts pests and worm eggs, crops are more vulnerable to underground pests. High temperature cannot be generated in the soil fermentation to kill harmful pathogenic bacteria and insect eggs in livestock feces, which will affect the growth of crops and even the health of consumers.

The high - quality biological organic fertilizer compost fermentation generally takes 45 to 60 days. It will kill harmful microorganisms with the warming and high temperature in the early stage of compost, such as pathogenic bacteria, insect eggs and grass seed, etc., in the later period, microorganisms begin to have humification to organic matter, and produces a large number of metabolites beneficial to plant growth and absorption. Compost can achieve three purposes, harmlessness; humification; a large number of microbial metabolites such as antibiotics, proteins and so on.Here is the image of biological organic fertilizer double screws compost turning machine

Principle of biological organic fertilizer fermentation:

The complex transformation of organic matter in compost under the action of microorganisms can be concluded into two processes: One is the process of mineralization of organic matter, that is, complex organic matter is decomposed into simple matter, and be generated into carbon dioxide, water, mineral nutrient. It can provide immediate nutrients for crops and microorganisms, provide energy for microbial activity, and prepare basic raw materials for humification of compost organic matter. When compost is dominated by aerobic microbial activity, organic matter rapidly mineralizes into more carbon dioxide, water and other nutrients, decomposes quickly and thoroughly, and emits a lot of heat energy. When the main activity is anaerobic microorganism, the decomposition rate of organic matter is slow, incomplete, and the release of heat energy is less. Besides the nutrients for plant growth, the decomposition are easy to accumulate organic acids and reducing substances such as CH4, H2S, PH3 and H2. When it reaches a certain level, it is unfavorable or even harmful to crop growth. Therefore, the turnover during composting fermentation is also to convert microbial activity to eliminate harmful substances.

Another is the humification process in our bio organic Fertilizer Compost Fermentation Equipment Processing Plant of organic matter, that is, organic matter is decomposed and resynthesized to produce more complex special organic matter - humus.

Fermentation technology of biological organic fertilizer compost: Compost is actually a form of waste stabilization, but it requires special humidity, ventilation conditions, and microorganisms to produce appropriate temperatures. Generally the temperature is higher than 45 ℃ to keep the high temperature can make the pathogen inactivation, and kill the weed seeds. The residual organic matter relatively stable and easy to be absorbed by plants, the stink can be greatly reduced after composting.

The composting process mainly depends on the action of microorganisms, The microorganisms have two sources: one is the large number of microorganisms existing in organic waste; The other is an artificially added microbe inoculant. These bacteria have a strong decomposition ability for organic waste, can accelerate the process and shorten the time of compost reaction.

Compost is generally divided into aerobic compost and anaerobic compost. Aerobic compost is a decomposition process of organic materials under aerobic conditions. Its metabolites are mainly carbon dioxide, water and heat. Anaerobic compost is the decomposition process of organic materials under anaerobic conditions. The final metabolites are methane, carbon dioxide and many intermediates with low molecular weight, such as organic acids. The main microbial species involved are bacteria, fungi and actinomycete in the composting process.

The fermentation process of our biological organic fertilizer compost fermentation processing plant -Zhengzhou Huaqiang

1. Medium temperature stage.

In the initial stage of compost production, microorganisms in compost are mainly of medium temperature and aerobic type, They start composting fermentation process, can decompose organic matter (such as a simple sugar, starch, protein, etc.) under aerobic conditions, and produce a significant amount of heat, constantly improve the composting temperature, has risen from about 20 ℃to 40 ℃.

2. High temperature stage

With the increase of temperature, thermophilic microbial gradually replace the medium temperature microbial and play a leading role, generally within a few days, the temperature is more than 50 ℃, and entered the stage of high temperature. At high temperatures, thermophilic actinomyce and fungi become the main species. They decompose complex organic substances (such as cellulose, hemicellulose, pectin substances) in the compost, accumulate the heat ,the compost temperature rise to 60-70 ℃, and even can be as high as 80 ℃. And most of the thermophilic microorganisms will be dead or to enter a dormant state, it has very important effect to accelerate the composting process in our biological organic Fertilizer Compost Fermentation Processing Plant .

3. Cooling stage

When the high-temperature stage lasts for a certain period of time, most of the cellulose, hemicellulose and pectin substances have been decomposed. Microbial activity becomes weakened and the temperature begins to drop. When the temperature drops to below 40 ℃, medium temperature microorganisms are the dominant species. At this time, you can turn over the compost heap by the fertilizer compost turning machine, mix the stacking materials evenly, so that it will produce a second heat to promote the compost decomposing. Generally, when the heap temperature crosses the peak and begins to cool down, turning over the heap can make the inner and outer layer decompose at different temperatures and remix evenly. If the humidity is insufficient, some water can be added to promote even compost maturation. Here we provide five types fermentation compost turning machines, they are mainly and widely used in organic fertilizer plant, compound fertilizer plant, sludge waste plant, gardening farm and BIS mushroom plant.including simple groove turning machine hydraulic type groove turning machine , double screws turning machine and chain compost turing machine, these four types machines are suitable for the groove compost, the last one compost machine is crawler turing machine, which can move freely and is suitable for the compost in the surface of the ground. After the compost processw, the next core part is granulating process in the organic fertilizer produciton line, Our designer can provide the customized the fermentation compost production line according to the capactity and raw materials for our clients. we have successful cases like nissan 200 tons organic fertilizer combination granulation production line , and 50,000 tons compouond fertilizer rotary drum granulation production line

4. Maturation and preserving fertilizer

When the compost was decomposed thoroughly, its volume begins to decrease, and the heap temperature drops to a little higher than the air temperature. At this time, compost should be pressed tightly, resulting in an anaerobic state, which will weaken the mineralization of organic matters, so as to facilitate the maintenance of fertilizer.

In short, the fermentation process of organic compost is actually the process of metabolism and reproduction of various microorganisms. Which is the decomposed process of organic matter. fermented organic fertilizer raw materials are crushed into fine powder, these powder enters into the new type organic fertilizer granulator , the granules fertilizer products are dried, cooled, screened, finanlly they are transported into the automatic packing machine and packed into bags of granules bio-organic fertilizer. How to make organic fertilizer production line factory introduces the details of bio-organic fertilizer production process.
