Production line of cow dung organic fertilizer
1.Using cow dung as fertilizer is the most commonly used method in tradition. When cow dung is used as fertilizer, the self-purification ability of soil can be applied, and cow dung can be directly applied to farmland without any disposal, this kind of application certainly saves labor and money. However, it is easy to pollute the environment and spread plant diseases and insect pests. According to relevant information, in some places, the pollution of cow dung to the environment has exceeded the total amount of industrial pollution, and some even have reached more than twice. A cow produces more than 7 tons of feces every year, and a scalper produces between 5 and 6 tons of feces.
Due to the lack of attention to the treatment of cow dung in various regions, there are basically no cow dung treatment facilities in some places where cattle are concentrated. In this way, cow dung is piled up everywhere, especially in the South. Every summer, it is smelly, which not only has adverse effects on the normal life of surrounding residents, but also is the source of Breeding and reproduction of various bacterial pathogens, it has a serious impact on the breeding population. In addition, when raw cow dung goes to the ground, it generates heat and consumes oxygen in the soil, which leads to burning roots and burning seedlings. It also plays a role in spreading parasite eggs and pathogenic microorganisms and does not advocate this kind of application. Therefore, cow dung should be disposed before being applied. Although the application cost is increased in this way, the fertilizer efficiency is also high, which can effectively promote the yield of crops. If mass production is formed, it has higher economic value and social value, and more importantly, it is beneficial to maintaining the environment. Production line and production process of cow dung organic fertilizer
2. Common cow dung treatment methods in cattle farms:
2.1 build biogas digester
In recent years, through the construction of biogas digester to deal with cow dung, the effect is very ideal. It not only solves the fuel source of the masses, but also makes the cow dung fully decomposed. The slag and liquid of biogas are very good organic fertilizers, it can improve the yield and quality of fruits and vegetables
2.2 Production of organic fertilizer
Dried cow dung contains 10%-20% crude protein, 1%-3% crude fat, 20%-30% nitrogen-free extract and 15%-30% crude fiber, so it has high nutrients. Organic fertilizer produced by fermentation of dry cow dung. It can fluffy soil, improve land hardening, chelate trace elements in land, improve soil fertility, etc.
Using cow dung as raw material to produce organic fertilizer has Cheng Benxiao, stable quality and large market sales space. However, the traditional method of piling up not only has a slow fermentation speed, but also can not make cow dung thoroughly decomposed. After being applied to the farmland, it Yi Fasheng "secondary fermentation", resulting in the phenomenon of burning roots and seedlings. Therefore, cow dung need to be added with cow dung starter which is a kind of anti-corrosion agent when fermenting cow dung, and the fermentation speed is fast. Generally, the processes of complete deodorization, fermentation and decomposition, insecticidal and sterilization of cow dung can be completed within 3 to 7 days. The fermented organic fertilizer has good fertilizer efficiency, is safe and convenient to use, does not cause the phenomenon of burning roots and seedlings, can also fertilize soil fertility, improve the utilization rate of chemical fertilizers, etc.
Through the above comparison, we can clearly understand that the value of organic fertilizer of cow dung is far higher than that of untreated raw cow dung. So, compared with the direct application of raw cow dung, how high is the cost of treating cow dung into organic fertilizer?
3. Price cost of cow dung organic fertilizer production line:
For cattle farms, the cost of processing cow dung into organic fertilizer mainly includes two aspects: one is the cost of site civil engineering, and the amount of investment varies from place to place, which generally costs 100,000 to 500,000 yuan, it mainly depends on whether there is a ready-made field in your cattle farm. If there is a field, you only need to build an organic fertilizer production workshop and a warehouse of 100,000 yuan, with a scale of 10,000 tons of cow dung organic fertilizer production line, covering an area of about 600-1000 square meters. The second is the cost of purchasing organic fertilizer production equipment. According to the size of production, the investment amount is generally 100-1 million. (Example: the price of a small organic fertilizer production line of 3,000-5,000 tons is generally 150,000-200,000)
According to the investment cost of organic fertilizer production equipment, two treatment schemes can be chosen: one is the organic fertilizer production line with relatively small investment amount, and this mode of organic fertilizer production has relatively high efficiency, the amount of investment is relatively small. The organic fertilizer production line with an annual output of 5,000 tons mentioned above is only about 200,000 yuan; The disadvantage is that the production process is not completely automated and is divided into multiple production processes, requiring manual assistance in production. The second is organic fertilizer fermenting tanks with relatively large investment amount. This mode of organic fertilizer production has only been introduced to the market in recent years. Although the investment amount is relatively high, the general market price is 500-1 million per set, however, its biggest advantage is that it saves time and labor, and the whole fermentation process is completed automatically only by putting the production raw materials into the silo by forklift. What I want to tell you today is mainly the most commonly used organic fertilizer production line in the market to produce cow dung organic fertilizer.
4. According to the production process flow chart of cow dung organic fertilizer, we can see that the equipment used in the production line of cow dung organic fertilizer includes: premixer, fermentation dumpling machine (or fermentation dumpling machine), pulverizer, disc granulator, sieving machine, packaging machine.
5. The production process of cow dung organic fertilizer mainly includes mixing, fermentation, crushing, granulation, drying, cooling, screening and packaging. The production capacity of a single production line equipment should be 1~10 t/h. If it is too small, it will not reach the economic scale. If it is too large, it will increase the difficulty of transporting and storing raw materials and finished products.
6. The technological process of cow dung organic fertilizer production line mainly consists of two parts: the early fermentation part and the later granulation part.
6.1 Pre-fermentation part
6.1.1 cow dung contains high water, so aerobic fermentation treatment is recommended. Organic fertilizer starter can be used for fermentation, which is better for crops.Dry or drain the recycled cow excrement to make its moisture below 85%, and then make appropriate proportion with straw, sawdust, mushroom residue, etc. (excrement accounts for 80-90%, others account for 10-20%) mixing. 1 ton of materials (about 2.5 tons of fresh materials) plus 1kg of organic fertilizer starter, plus 5kg of rice bran (or substitutes such as bran and corn flour) according to 1kg of organic fertilizer starter after dilution, evenly spread into the material pile. Pay attention to proper oxygen supply and heap turning during fermentation, and the temperature should be controlled between 55-65 ℃.The water content of fermentation materials should be controlled: the water content of livestock manure such as fermented cow dung should be controlled between 40 and 65%.
Moisture that suits or not judgment way: hand grab a cow dung, fingers see watermark, but not dripping, floor that powder is appropriate. Less water, slow fermentation, more water, poor ventilation, therefore, we must grasp the water content. If the moisture is too high, straw, sawdust, mushroom residue, dry soil powder and so on can be added.
Mix well and ventilate: cow dung fermentation to produce organic fertilizer requires good (oxygen consumption) fermentation. Therefore, in the process of operation, oxygen supply measures should be increased so that it is better to mix well, turn over frequently and ventilate. Otherwise, it will cause odor caused by anaerobic fermentation and affect fertilizer effect.
6.1.2. The organic fertilizer equipment used in the fermentation process includes ground tipper or trough tipper. Pile the ground noodles and use the ground Tipper; Put materials into the fermentation tank and use the trough tipper.
6.1.3, the fermentation is completed in 7-12 days, and the number of turning piles varies according to the temperature in different places. Generally, after 48 hours of cow dung accumulation, the temperature rises to 50 ~ 60℃, and can reach above 65℃ on the third day. Under this high temperature, the cow dung is turned over once. Under normal circumstances, in the fermentation process, there will be two times of high temperature above 65℃. If you turn over twice, the fermentation can be completed, and the fermentation can be completed within a normal week. The material is dark brown, and the temperature begins to drop to normal temperature, indicating that the fermentation is completed.
6.1.4. Fully fermented, decomposed and out of the pond (ground type directly using forklift to pile up)
6.2 late granulation part
6.2.1 screening. The raw materials of the fermented organic fertilizer are screened by grading sieve, and the screened powdery fertilizer can be sold directly.
6.2.2 material return system. The filtered large pieces of materials are transported to the pulverizer for crushing and then returned to the grading screen through the automatic material return system.
6.2.3 granulating with granulator. (Example: a 3000cm disc granulator has a motor power of 11kw and an hourly output of 5-6 tons.)
6.2.4 drying. Use the organic fertilizer dryer to further remove moisture from the granulated organic fertilizer particles to meet the standard requirement of moisture content of organic fertilizer. (It can be selected according to the scale, and the production line of cow dung organic fertilizer with smaller scale can save the secondary equipment)
6.2.5 cooling. Cooling particle materials by cooling machine is helpful for particle storage and quality assurance.
6.2.6 automatic packaging machine packaging for sale. The cooled granular materials are transported into the finished product warehouse by bucket elevator. Granular materials realize quantitative weighing and packaging through automatic packaging and weighing. It can realize the integration of automatic weighing and sewing of 3-6 bags per minute.
