Bioreactor Process Flow | Organic Fertilizer Rapid Manufacturing Equipment

Chemical fertilizers, due to their direct and immediate effects, are still heavily relied upon in modern agricultural practices across various regions. After three to five years of intensive chemical use, soil's natural fertility significantly declines with the continuous application of chemicals each year. This decline necessitates an increasing amount of chemical fertilizers each year to maintain high yields, leading to higher costs and accelerating the soil's overall degradation. In recent years, organic fertilizer production in some areas has been primarily designed to handle urban waste, resulting in organic fertilizers rich in garbage, particularly indigestible chemical products, which severely disrupt the farmland ecosystem. This is detrimental to soil health and crop growth. Traditional composting methods involve piling up straw, leaves, vegetable scraps, sawdust, and manure, allowing them to ferment over time into suitable fertilizer for the fields. This mixed fertilizer is beneficial for the humus in farmland, but to produce it, these materials must be piled for a long duration and continuously stirred. Even then, not all materials can be evenly fermented; some decompose fully while others do not. Additionally, the composting process generates a significant amount of harmful gases, polluting the environment.
With the development of society, people are increasingly inclined towards green and environmentally friendly foods. Foods grown with organic fertilizers are also gaining popularity. The raw materials for organic fertilizers are abundant, including organic waste such as withered leaves, straw, and animal manure. Compared to chemical fertilizers, organic fertilizers have higher nutritional value and do not degrade soil quality, causing problems like compaction and poor aeration. Liquid organic fertilizers are a crucial source of organic fertilizer, easily absorbed by soil and playing a significant role in increasing crop yields, which is why they are well-received by farmers. However, currently, the fermentation of organic fertilizers typically occurs in fermentation ponds or tanks, generating a large amount of heat during the process. This requires stirring and cooling, which is usually done with fermentation pit turnover equipment, leading to high costs and inconvenience. Moreover, the large amount of heat produced during fermentation cannot be utilized, resulting in resource waste.

The composting process involves numerous types of microorganisms, which vary in number due to changes in raw materials and conditions. No single microorganism dominates throughout the composting process. Each environment hosts a unique microbial community, and the diversity of microorganisms prevents system collapse even when external conditions change. The composting process primarily relies on the actions of microorganisms, which are the main agents of compost fermentation. Microorganisms participating in composting come from two sources: a large number of microorganisms originally present in organic waste, and artificial microbial inoculants added to the mix. These strains have strong decomposition capabilities for certain organic wastes under specific conditions, characterized by high activity, rapid reproduction, and quick decomposition of organic matter. They can accelerate the composting reaction and shorten the reaction time. Composting is generally categorized into aerobic and anaerobic composting. Aerobic composting is the decomposition of organic materials in the presence of oxygen, with metabolic products mainly being carbon dioxide, water, and heat. Anaerobic composting is the decomposition of organic materials in the absence of oxygen, resulting in metabolic products such as carbon dioxide and many low-molecular-weight intermediate products, such as organic acids.

As modern agriculture progresses, rural environmental pollution issues have become increasingly prominent, with their危害 now surpassing industrial pollution, necessitating urgent systematic treatment. The primary sources of rural environmental pollution include: breeding wastewater pollution, breeding feces pollution, rural solid waste pollution, excessive agricultural fertilizer pollution in farmlands, and pesticide pollution. Faeces and faecal water contain a large number of pathogenic microorganisms and pests, generate odors, and, when applied to soil, cause farmland pollution. They also pose direct threats to human and livestock safety through the food chain. The rectification of rural environmental pollution sources is imperative, and how to scientifically and effectively address rural, agricultural, and farmland pollution issues is a pressing matter.

Compost primarily utilizes the actions of various microorganisms to mineralize, humify, and render harmless organic residues, converting complex organic nutrients into soluble nutrients and humus. Simultaneously, it harnesses the high temperatures (60-70°C) generated during the composting process to kill pathogens, eggs of pests, and weed seeds present in the raw materials, achieving the goal of harmlessness. Therefore, to produce compost, creating optimal conditions for the microorganisms' life activities during the composting process is crucial for accelerating decomposition and enhancing fertilizer efficacy.
Chicken manure organic fertilizer advantages:
Compared to fertilizers
In our country, for many years, the excessive use of chemical fertilizers has led to a shortage of organic fertilizers, imbalanced nutrient ratios, and adverse effects on the farmland ecological environment, soil physical and chemical properties, and soil microorganisms. Using organic fertilizers can avoid these issues.
2. Compared to farmyard manure
What's the difference between our organic fertilizer and the compost made by farmers? Generally speaking, organic fertilizer that hasn't been treated to eliminate pathogens has several drawbacks: Firstly, it contains high levels of salt, which can lead to soil salinization, uneven seedling emergence, and slow root growth; secondly, it carries a high risk of harboring diseases and pests; thirdly, the nutrient content is inconsistent, making it impossible to ensure sufficient nutrients and prone to burning seedlings and roots.
3. Social and Environmental Significance
Increasing the proportion of organic fertilizer used in China can also avoid the following issues: - It can prevent the large accumulation of agricultural waste, nutrient loss, and environmental pollution. - It can mitigate the severe potassium deficiency in soil and crops, which greatly reduces soil fertility. - It can reduce the use of chemical fertilizers, as the share of agricultural waste in pollutants has reached 35%-40%.
