Shunxin - Cow Dung Dewatering Machine
From Precompost
Cow dung manure on the farm will cause bacterial growth if it is not treated in time, and it will also induce some infectious diseases. Now many farms are using cow dung manure dewatering machine and treated by cow dung manure dehydrator. The fertilizer has a high nutrient concentration, is easy to decompose, and absorbs quickly. Then, how is it processed into fermented organic fertilizer?

How to process fermented organic fertilizer with cow dung manure dehydrator?
The following 6 steps in the cow dung manure organic fertilizer production just for your fertilizer making plants reference.
- Preparation of bacteria: Prepare the manure that needs fermentation. It should be fresh cow dung manure (the fermentation effect of fresh manure
- is better than that of old manure). For example, about 1 ton of fresh cow dung manure plus 0.25 kg of cow dung manure starter must first be mixed
- with rice bran (or corn flour, wheat bran) at a ratio of 1:5 to 10 for use.
- Cow dung manure piling: the prepared cow dung manure while sprinkling bacteria, should be piled, and the pile height and volume cannot be too
- short and too small. Requirements: stack height 1.5-2 meters, width 2 meters, length is not limited.
- Adjust moisture. The moisture content of fermented cow dung manure should be controlled at 40-65. Moisture judgment: hold a handful of cow
- dung manure with your hand, see the watermark on the fingertips but do not drip, and it is appropriate to land. Slow water fermentation, poor
- water and poor ventilation, can also lead to the smell of spoilage bacteria, so it is necessary to grasp the moisture content.
- Starting temperature. The starting temperature should be better than 15 °C (the four seasons can be operated, not affected by the season, and the
- winter should be fermented indoors or in the greenhouse), and the fermentation temperature should be controlled below 70-75 °C
- Mix well ventilation. Cow dung manure starter needs good (consumption) oxygen fermentation. Therefore, during the operation process, oxygen
- supply measures should be increased to achieve uniform mixing, diligent turning and ventilation. Otherwise, it will lead to anaerobic fermentation
- and produce odor, which will affect the fertilizer effect.
- The fermentation is completed. Generally, after 48 hours of cow dung manure accumulation, the temperature rises to 50-60 ° C, and the third day
- can reach 65 ° C or above. At this high temperature, it should be tipped over. Under normal circumstances, there will be two times above 65 ° C
- during the fermentation process. High temperature, the fermentation can be completed twice, and the fermentation can be completed within one
- week. The material is dark brown and the temperature begins to drop to normal temperature, indicating that the fermentation is completed.
Advantages
The cow manure dehydrator produced by our factory has the following advantages
- The cow manure dewatering machine produced by our company is made of GB 304 stainless steel and alloy steel. The structural components such as screen mesh are made of nickel alloy steel and high strength carbon steel to ensure the corrosion resistance and strength of the machine. The dewatering machine is very convenient to clean and maintain. When it is used normally, the screen can be cleaned every five months. When cleaning, first remove the bolt of the discharge port, then take out the screen and clean the block with water. When it is clean, so that it can ensure that the processing is smooth and does not cause blockages.
- This series of dewatering machine has high degree of automation, low power consumption, low price, easy to operate, just press the start and stop button, you can operate the machine. It only needs one person. The water content of cow manure feed in summer is between 80% and 90%. After the cow manure is treated, the water content is between 30% and 40%.
How it Work
How does the cow manure dehydrator work?
- Use the submerged pump to lift the raw manure water to the cow manure solid-liquid separator. The extruded auger will gradually push the cow manure to the front of the body, while continuously increasing the pressure on the leading edge, forcing the water in the material to the side. The mesh screen is extruded under the action of the pressure belt filter, and the drain pipe is discharged.
- The cow manure solid-liquid separator can work continuously, and the material is continuously lifted into the machine body. The pressure at the leading edge is continuously increased. When it is large to a certain extent, the discharge port is opened and extruded. Its wide mouth design is to achieve the purpose of extrusion and discharge.
- If too much fecal water is drawn, it will also be discharged into the original septic tank through the overflow pipe. The waste water separated by spiral extrusion can be directly sent to the sedimentation tank.
