1. Enterprise profile: Deeply cultivate organic circulation and empower green agriculture

Fudiyuan Engineering Equipment (Henan) Co., Ltd. is a high-tech enterprise focusing on the harmless resource utilization of organic waste and the research and development and production of biological organic fertilizer equipment. Based in the Central Plains, radiating the whole country, the company has built a research and development from the core strain with the mission of "turning organic waste into treasure and protecting green waters and green mountains"→ complete equipment manufacturing →Engineering scheme design→ the whole industry chain service system of operation and maintenance technical services.

Relying on a strong R&D team and mature production system, Fudiyuan has successively launched a series of products such as liquid fermentation systems, static aerobic fermentation equipment, and decomposing bacterial agents, which are widely used in livestock and poultry breeding, agricultural planting, environmental protection treatment and other fields, providing thousands of customers with efficient, environmentally friendly and economical organic waste treatment solutions, and becoming an important force in promoting the green transformation of agriculture and rural revitalization.

2. Core technology: efficient conversion code of liquid fermentation

(1) Core driving force: Fudi source decomposing agent

The core competitiveness of Fudiyuan liquid fermentation system lies in the supporting use of self-developed decomposing agents - this is the company's cooperation with key agricultural colleges and microbiology institutes, gathering experts in microbiology, environmental engineering, agricultural science and other fields. After 8 years of repeated screening, domestication, compounding and field testing, the highly efficient compound microbial preparation tailored for the liquid fermentation process is the "biological engine" to realize the rapid harmlessness, resource utilization and efficient transformation of organic wasteIt fills the industry gap of insufficient adaptability and low decomposition efficiency of special bacterial agents for liquid fermentation in China.

The bacterium is based on Bacillus, Lactobacillus, Actinomycetes and Functional Yeast as the four core strains, with a variety of auxiliary functional microorganisms, through scientific ratio to form a stable and efficient microecological synergy system, each strain has a clear division of labor and synergy at different stages of fermentation, and controls the degradation and decomposition process of organic waste throughout the process. Ensure that the fermentation efficiency and product quality are up to standard.

Among them, Bacillus is the "vanguard force" of bacterial agents With its strong environmental adaptability and enzyme production ability, it has become the core force to initiate fermentation. It can secrete a large amount of cellulase, protease, amylase, lipase and other active enzymes, quickly decompose cellulose, hemicellulose, protein, fat and other macromolecular organic matter in straw, livestock and poultry manure, kitchen waste, etc., and decompose them into small molecule peptides, amino acids, simple sugars, fatty acids and other nutrients that can be further used by microorganisms, laying a solid material foundation for the subsequent fermentation process. At the same time, Bacillus has strong high temperature resistance, acid and alkali resistance, and osmotic pressure resistance, and during the fermentation process, even if the ambient temperature rises above 55 °C, it can still maintain high activity, quickly occupy the microecological advantage, inhibit the growth of spoilage bacteria and pathogenic bacteria, and create a stable microenvironment for the fermentation process.

As the "regulators" of the fermentation process, lactic acid bacteria and yeast play an important role in optimizing the fermentation environment and improving the quality of products. Lactic acid bacteria produce organic acids such as lactic acid and acetic acid through metabolism, and accurately adjust the pH value of the fermentation system to 5.5~7.0It can not only provide good conditions for the growth and reproduction of beneficial bacteria, but also effectively inhibit the activity of harmful microorganisms such as Escherichia coli, Salmonella, and mold, eliminate the odorous gas (such as ammonia, hydrogen sulfide) generated during the fermentation of organic waste from the source, and completely solve the problem of odor disturbance and breeding of mosquitoes and flies in the traditional fermentation process. Yeast can use small molecule carbon sources to rapidly proliferate, secrete vitamins, amino acids, growth factors and other nutrients, and provide nutritional support for the continuous metabolism of core strains such as Bacillus and actinomycetes.

Actinomycetes act as "quality improvers" in the later stage of fermentation , mainly responsible for the synthesis of humus and the stabilization of fermentation products. In the later stage of fermentation, when the macromolecular organic matter is fully degraded, actinomycetes will multiply in large numbers, converting small molecule nutrients into stable humic acid, fulvic acid and other humic substances, which can not only improve the fertilizer persistence of liquid organic fertilizer, but also improve the soil structure, promote the formation of soil aggregates, and improve the soil water and fertilizer retention capacity. At the same time, actinomycetes can secrete a variety of antibiotic substances, further inhibit the activity of pathogenic bacteria, ensure the safety of fermentation products, and avoid secondary pollution to crops and soil during subsequent application.

Compared with ordinary commercially available bacterial agents, Fudiyuan decomposing bacterial agents have four core advantages after long-term research and development and practical optimization, which are fully adapted to the operation needs of liquid fermentation systems and demonstrate unique technical competitiveness.

First, the environment is extremely adaptable and has a wide range of adaptation. The agent can be used in a wide temperature range of 15°C~45°C and pH value of 5.5~8.5Whether it is winter fermentation in low-temperature areas in the north or summer operations in high-temperature and high-humidity areas in the south, whether it is processing high-fiber straw, high-nitrogen livestock and poultry manure, or high-moisture kitchen waste, the fermentation process can be stably started, and the bacterial agent will not be inactivated and fermentation stagnation due to raw material differences and environmental changes, which effectively solves the pain points of poor adaptability of traditional bacteria and obvious geographical restrictions.

Second, the decomposition efficiency is extremely high, greatly increasing production capacity. Relying on the synergy of the strains and the efficient enzyme production ability, Fudiyuan decomposing agent can shorten the decomposition cycle of traditional composting of 30~60 days to 7~15 days, with the closed aeration and uniform stirring process of the liquid fermentation system. The degradation rate of organic waste has increased by more than 40%, greatly shortening the treatment cycle of equipment, increasing the treatment capacity per unit time, helping customers reduce time costs and labor costs, and improve economic benefits.

Third, the functional complexity is outstanding, taking into account environmental protection and fertilizer efficiency. The agent can not only achieve rapid decomposition of organic waste, but also complete harmless treatment simultaneously, effectively killing pathogenic bacteria, insect eggs and weed seeds in organic waste, with a killing rate of more than 95%, avoiding the risk of pollution to crops and soil after the application of fermentation products. At the same time, the number of beneficial live bacteria in the agent ≥ 2 billion CFU/gAfter the fermentation is completed, a large number of active beneficial bacteria can still be maintained in the liquid organic fertilizer, which can be quickly colonized after being applied to the soil, improve the balance of soil microecology, inhibit the reproduction of harmful pathogens in the soil, improve the resistance of crops to diseases and pests, and at the same time convert inert nutrients such as nitrogen, phosphorus, potassium and other inert nutrients in the soil into a fast-acting form that is more easily absorbed by crops, taking into account the fast-acting fertilizer effect and long-term fertilizer effect, and helping the crop to improve quality and yield.

Fourth, the adaptability is precise and perfectly compatible with the equipment. Fudiyuan decomposing agent is specially developed for the optimization of liquid fermentation process, which can maintain good dispersion and activity in a liquid environment with high moisture and high flow, and will not cause problems such as agglomeration and precipitation. At the same time, it is perfectly compatible with the automatic precision dosing system of the liquid fermentation system, which can realize the precise dosing of bacterial agents according to the type and concentration of organic materials, ensure that the bacterial agents and materials are fully mixed, avoid the problems of uneven local fermentation and incomplete decomposition, and ensure the stable and consistent quality of each batch of fermentation products.

In the actual operation of the liquid fermentation system, Fudiyuan decomposing agent is fully mixed with organic materials according to scientific proportions through the automatic dosing system, and after entering the closed fermentation tank, it reproduces and metabolizes rapidly in the environment of precise temperature control, continuous aeration and uniform stirring, and participates in the degradation and decomposition process of organic waste throughout the process. It not only accelerates the mineralization and humification of organic matter, but also effectively degrades harmful substances in organic waste, reduces the generation of exhaust gas and leachate during the fermentation process, and achieves environmentally friendly discharge. The final liquid organic fertilizer is uniform in color, odorless, rich in humic acid, amino acids, beneficial live bacteria and a variety of medium and trace elements, and can be directly used for drip irrigation, flushing, foliar spraying, adapting to the planting needs of various crops, fruits and vegetables, and flowers, providing high-quality, green and efficient fertilizer sources for agricultural production, and truly realizing "turning waste into treasure" Promote the sustainable development of organic circular agriculture.
