What are some common methods of treating cow manure?

With the development of cow breeding industry, cattle littter dispoal has been a difficulty for farm owners. There are two methods are commonly used by them for cow waste management.

In recent years, through the construction of biogas digesters to treat cow dung, it not only solves the fuel source of the masses, but also makes the cow dung fully decomposed. The residue and liquid of biogas are good organic fertilizers, which can improve the yield and quality of fruits and vegetables.

Converting cow crap into organic fertilizer

Dry cow dung contains 10%–20% crude protein, 1%–3% crude fat, 20%–30% nitrogen-free extract, 15%–30% crude fiber, so it has high nutrients. Organic fertilizer produced by cow dung compost  can loosen soil, improve soil compaction, chelate trace elements in the soil, and improve soil fertility. Click here for concrete process of cow dung organic fertilizer production

Using cow dung as raw material to produce organic fertilizer has characteristics of low cost, relatively stable quality and large market sales space. However, the traditional method of composting not only has a slow fermentation speed, but also cannot make the cow dung fully decomposed. After being applied to the farmland, “secondary fermentation” is prone to occur, resulting in the phenomenon of burning roots and seedlings. Here, you need a organic fertilizer composting machine. It will turn cow litter regularly to facilitate aerobic fermentation. In 15 to 20 days, it can help you finish the deodorization, fermentation, insecticide and sterilization of cow dung. The fermented organic fertilizer has good fertilizer efficiency, is safe and convenient to use, will not cause burning of roots and seedlings, and can also improve soil fertility and improve the utilization rate of cattle manure.

The following equipment will be used in animal manure fertilizer making:

• Fermentation  and compost equipment: There are many types of fermentation stackers, chain plate stacker, trough stacker, mobile stacker, crawler stacker, you can do it by yourself choose, you can also consult us, we will recommend the appropriate model equipment for you.
• Pulverizing equipment: new semi-wet material pulverizer, vertical pulverizer and horizontal pulverizer, the internal structure has chain type and hammer type. Even if the material is pulled out of the water and crushed, it will not block.
• Mixing equipment: including vertical mixer, horizontal mixer, double shaft mixer, drum mixer, etc. The internal stirring structure is divided into stirring blade type, spiral type and so on.
• Design a suitable stirring structure according to the characteristics of the material. The discharge port is designed for cylinder control and baffle control.
• Conveying equipment: belt conveyor, mobile belt conveyor, fixed belt conveyor, etc. Belt conveyor is an indispensable economical logistics conveying equipment to form a rhythmic assembly line. It has strong conveying capacity and conveying distance. It has the advantages of long distance, simple structure, easy maintenance, and convenient implementation of programmed control and automatic operation.
•  Granulation making equipment: special granulator for organic fertilizer – including disc granulator, new type of organic fertilizer granulator, rounder, drum granulator, etc. According to the characteristics of raw materials, choose the appropriate granulator. Drying and cooling equipment: rotary dryer, biological organic fertilizer dryer, because the temperature of organic fertilizer cannot exceed 80°, so our dryer adopts hot air drying mode.
• Cooler: Similar in appearance to the dryer, but different in material and performance.
• Automatic packaging equipment: automatic metering packaging machine – including single head and double head, materials are stainless steel and carbon steel, and can customize according to the actual needs of customers.

Through the above comparison, we can clearly understand that the value of cow dung organic fertilizer is much higher than that of untreated raw cow dung. So making cow dung into organic fertilizer is an good choice for you.
