What equipment can be used for fertilizer compost?

In the fermentation process of organic fertilizer, it can be divided into anaerobic fermentation and aerobic fermentation.

In the anaerobic fermentation of composting, anaerobic microorganisms are mainly used to carry out a series of decomposition processes under the condition of anoxic and anoxic conditions, so as to the materials are suitable for making fertilizer, and the final product is methane with a small amount of carbon dioxide and humic organic matter. There will also be other organic acid reducing substances such as sulfuric acid and ammonia. The composting process is simple and requires no manual operation, but the reaction speed is slow, the composting cycle is long, and the removal of harmful substances is incomplete.

Aerobic fermentation refers to the process of stably converting organic matter materials into humus fertilization by artificially configuring appropriate CN ratio, moisture, oxygen (ventilation), temperature and other environments to promote mass reproduction and decomposition of microorganisms. The final product of this type of fermentation can achieve maximum removal of harmful organic matter.  For this, SX can provide you with suitable fertilizer composting line.

In the process of aerobic fermentation, it is necessary to build a fermentation workshop, stack the organic materials in batches in the fermentation workshop, manually adjust the CN ratio of the organic materials, adjust the moisture appropriately, and ferment after adding beneficial bacteria. , During the fermentation process, by observing the activity and reproduction of the bacteria through the change of temperature and humidity, the appropriate use of fertilizer turning machines (wheel type turning turning machines, crawler turning turning machines, trench turning turning machines) is used to process the materials.

The turning and throwing can make the bacteria fully contact with oxygen, play the role of ventilation and contact with oxygen, so that the bacteria can reproduce and decompose organic matter better. At the same time, during the stacking process, the bacteria will release a lot of heat during the decomposition process. When the heat reaches a certain temperature, the microorganisms will not be able to survive. The composting process can also fully cool the microorganisms and achieve a suitable environment for the decomposition and reproduction process.

In the fermentation of organic materials, the assistance of a fertilizer turning machine can simplify the fermentation time period. Generally, organic fertilizer manufacturers use trench type fermentation in the construction of organic fertilizer fermentation workshops, and use brick-concrete structure to build the construction workshop as the organic fertilizer fermentation raw material storage place. The general construction is 4 meters or 5 meters wide. Tracks are laid on both sides of the organic fertilizer fermentation tank, and the turning rack is set on the track on the fermentation tank. The track is combined with the organic fertilizer turning machine, and the turning machine can pass the track. The organic material in the tank is fully tossed. A single wider trough can be selected with an organic fertilizer roulette turner. Ordinary or hydraulic organic fertilizer turning machines can be used for multi-channel troughs. In some places that are not suitable for building organic fertilizer fermentation tanks, organic fertilizer crawler type turning machines can be used to store organic materials in strips, and organic fertilizer crawler type turning machines can be used for successive turning.If you want to know more information, please check  https://fertilizerequipmentmanufacturer.com/compost-fertilizer-making-machine/

The organic fertilizer trench turning  machine is generally composed of 16# or 22# channel steel as the main body, welding the main frame, installing the main shaft, turning teeth, motor reducer, traveling motor, hydraulic pump station, etc. The trench turning  equipment is economical and practical, and the operation is simple. It is the choice of most organic fertilizer manufacturers.

What Stages Are Involved In Small Scale Organic Fertilizer Composting?

General stage devision

The small scale organic fertilizer composting generally can be devided into two stages, namely the first high-temperature compost decomposed fermentation stage and the second aging stage. During this process, the unstable organic matter is transformed into stable humus through the decomposing process and under the action of microorganisms. Here, SX can provide you with high quality equipment for samll scale fertilizer fermentation

Let’s talk about the first stage : by proportioning the raw material matrix, the compost will absorb high oxygen, generate high temperature, greatly reduce the degradable volatile solids, gradually reduce the odor, and gradually change the color of the compost pile, and it is necessary to maintain good aeration and moisture control. .

Secondary composting of samll scale composting : The temperature initially decreased, the oxygen absorption rate decreased, and the odor completely disappeared.

Compared with the first compost, the second compost cannot be used without the second compost, because the second compost can degrade the refractory organic matter, and the mesophilic microbial colony can be re-established, thereby helping the organic fertilizer to decompose, reducing phytotoxic substances and inhibiting pathogenic bacteria.  Click here for more details

Ddeviding from temperature changing

The temperature change of organic fertilizer can define whether it is decomposed or not.

Temperature rising stage:

The decomposing temperature of organic fertilizer rises to 45℃, mainly actinomycetes, fungi and bacteria, mainly decompose sugars and starches. Even active biological animals and animals are involved.

High temperature stage:

The decomposing temperature reaches above 45°C, mesophilic microorganisms are inhibited, and thermophilicity dominates. Soluble organic matter continues to be decomposed by oxidation, and complex organic matter (cellulose, hemicellulose, protein, lignin) also begins to be decomposed. Around 50°C (thermophilic fungi and actinomycetes); around 60°C (thermophilic bacteria and actinomycetes); around 70°C (most microorganisms have been unable to adapt).

The optimum temperature for decomposing is 55°C, because most microorganisms are most active at this temperature and are most likely to decompose organic matter, and most of the germs, eggs and weed seeds will be killed. Please check https://fertilizerequipmentmanufacturer.com/small-scale-composting/ , you can find many equipment to help you in this espect.

Temperature falling stage:

Mesophilic microorganisms start to multiply again, take the lead, and further decompose the remaining refractory organic matter. At this time, the activity of microorganisms decreased, the oxygen demand of the compost to decompose decreased, the temperature decreased, and the compost gradually became stable.
