Fermentation Tank For Cow Dung Bio Fertilizer Composting

Cow dung is a common farmyard manure raw material. The output of cow dung is very large. On average, a cow produces about 20 kilograms of manure a day, and a farm with 50 cows produces about one ton of manure a day. A large amount of cow dung accumulation will seriously pollute the surrounding environment. Fermenting cow manure compost and making cow dung into bio-fertilizer is a good way to solve this problem. But the traditional cow dung composting method is slow and the deodorizing effect is not obvious. It only takes about seven days to compost cow dung bio-fertilizer with fertilizer fermentation tank.

Production process of cow dung compost

When you astart cow dung bio-fertilizer production for the first time, the fermentation bacteria must be added at the same time as the raw materials are added.

After fermentation, there is no need to add fermentation bacteria when feeding again, and the microorganisms produced in the tank can continue to ferment.

The cow dung fermenter equipment uses the decomposition of aerobic microorganisms in nature to compost cow dung. The activity of aerobic microorganisms undergoes continuous aerobic fermentation in a closed fermenter to decompose organic matter. The high temperature generated by itself will decompose the material, kill pathogens and other harmful substances, reduce the moisture content of the material, reduce the volume, and eventually produce a bio-organic fertilizer rich in a large amount of organic matter. Aerobic fermentation is a treatment method for obtaining organic fertilizer with less odor and energy saving.

Cow dung fermentation organic fertilizer fermentation tank process:

The processing of cow dung with organic fermentation tank generally includes four processes of feeding, high-temperature fermentation, decomposing, discharging, and stacking and stabilizing treatment.

  • Material loading: Put the material into the hopper with a bucket truck, and automatically load the material into the fermentation tank with one key.
  • High-temperature fermentation and decomposing: the vertical fermentation tank has a vortex air pump to send oxygen through the aeration holes on the stirring shaft, and at the same time the stirring shaft is stirring, and the temperature is gradually raised to 50-65 degrees under the action of aerobic bacteria agent. After more than 7 days of high-temperature fermentation Ripe. Effectively kill insect eggs, pathogenic bacteria and weed seeds, and achieve harmless and reduction treatment standards.
  • Material discharge: The material in the fermentation chamber falls layer by layer under the stirring of the main shaft and the action of gravity. After the fermentation is completed, the finished material is discharged from the discharge port

After the livestock and poultry manure is fermented by the bio-organic fertilizer and the fermenter, the fertilizer effect is better, the use is more convenient, and the utilization rate of chemical fertilizers can also be improved. The two can not only ferment cow dung, but also various poultry manure such as chicken manure, sheep manure, pig manure can be fermented into bio-organic fertilizer, and the fermentation method is basically the same.

Afterwards, as long as the normal feeding and production keep the fermentation process going, comprehensive stirring, ventilation, heat insulation and other measures are realized through the operation of the fermenter, and an excellent environment suitable for microbial reproduction can be created, the reproduction speed of microorganisms can be greatly accelerated, and the “biological fermentation” can be promoted. -The process of “harmless treatment of livestock and poultry manure and carcasses” realizes large-scale and factory-like treatment.

Process of High Quality Bio Fertilizer Manufacturing

There are a large number of beneficial microorganisms in bio-organic fertilizers, which can decompose organic matter in the soil, increase the aggregate structure of the soil, and improve the soil composition. Microbes multiply very fast in the soil, they are like an invisible web, intricate and intricate. After the microbial cells die, many tiny pipes are left in the soil. These tiny pipes not only increase the air permeability of the soil, but also make the soil fluffy and soft, and the nutrients and water are not easily lost, which increases the soil water storage and fertilization. Ability to avoid and eliminate soil compaction. So many people start investing in bio fertilizer making plant.
The beneficial microorganisms in the bio-organic fertilizer can also inhibit the reproduction of harmful bacteria, so that we can use less pesticides. If applied for many years, it can effectively inhibit soil harmful organisms, save labor, money, and no pollution.

However, when using the bio-organic fertilizer production line to make fertilizer, it must be thoroughly fermented and decomposed, so that the pathogenic bacteria and eggs in poultry manure such as cow dung, pig manure and chicken manure can be effectively eliminated, and the nutrients in the manure can also be decomposed into small molecular substances that can be directly absored and utilized by plant . The specific bio-organic fertilizer manufacturing technologies is as follows:
1. Adjust the initial moisture content of the bio-organic fertilizer fermentation material to about 60%. When the humidity is too high, straw, slag, cake, etc. can be added. The fermentation inoculum can be fully mixed with fine powder materials such as rice bran in advance and then scattered on the surface of the fermentation material pile. If the particle size of the auxiliary materials is too long or too large, it may wind up the turning gear of the bio fertilizer turning equipment in the later stage, causing turning over. Problems such as uneven heap or reduced work efficiency can be crushed with the help of special crushing equipment for straw.
2. During bio fertilizer fermentation, the temperature is controlled between 50~70°C and maintained for at least 7~10 days. This temperature refers to the temperature in the mid-temperature stage of bio-organic fertilizer fermentation. When the temperature of the heap continues to rise, it is necessary to use the bio-organic fertilizer turner to turn the heap, which can not only control the internal temperature, but also speed up the heap. Body water evaporates quickly. This is also an effective method to increase the internal porosity and avoid the anaerobic reaction of hypoxia to produce odor. Turn the heap every 2 to 3 days. The specific temperature of the heap is used as the standard. When the temperature begins to drop and continues to drop, stop turning the heap and let it stand for about a week to decompose before fertilizing.

3. After composting, in order to increase the nutrient content of the bio-organic fertilizer and improve the commerciality, a certain amount of N, P, and K can be added, and after mixing evenly with a horizontal mixer, granulation is carried out, so that the nutrients can be locked evenly and consistently. Among the particles, the phenomenon of uneven distribution is avoided. When the output is small, the dry granulator can be used for granulation, the granulation effect is good, the hardness is moderate, and the drying and cooling links can be omitted in the later stage; when the output is large, the SX rotary drum granulator can be used for granulation. granules, the ball formation rate is as high as 90%.
4. After granulation, screener and coater are used to further improve the appearance of the product. The particle size is consistent and the appearance is glossy, which attracts the attention of consumers. The higher the “face value” and “quality” of organic fertilizers, the higher the performance of the product, and the price will naturally increase. higher.
5. Packaging, the finished organic fertilizers are packaged in bags using a quantitative weighing packaging machine, and then they can be sold.
