Cow manure is more popular organic fertilizer raw materials, manufacturing equipment and technology has been gradually improved, increasingly mature, coupled with the current organic fertilizer factory some policies and subsidies, organic fertilizer production employees are still relatively popular. At present, the common organic fertilizer general production equipment on the market, honey includes a set of processes from the fermentation of organic fertilizer to packaging, generally speaking, now do organic fertilizer or very convenient.
In fact, cow dung contains large nutrients needed for crop growth. If it can be well used, it can not only protect our living environment, but also be a good entrepreneurial project. A cow produces about 30-40 kg of excrement per day, and a cattle farm with 5,000 cows can set up a small organic manure production line. So how to make fertilizer from cow dung? Next, we will briefly introduce it.
One, cow dung compost making in large scales:
In fresh cow dung added moisture less than 60% of organic solid solid wastes (such as straw, sawdust, rice bran, bean cake, etc.) as excipients and microbial fermentation bacterium agent mixed with, to rise to adjust the moisture, ventilation, and carbon and nitrogen than action (carbon and nitrogen ratio between 30 to 40), and makes the control of cow dung in the water content was 60%, with fingers have watermark but not dripping shall prevail. It was fully decomposed, sterilized, deodorized and dehydrated by continuous aerobic fermentation.
The moisture content of the decomposed material is generally in the range of 30-35%. After screening, it can be directly used for granulation to produce granular or powdery organic fertilizer.
The water content of 65%-85% fresh cow dung and appropriate auxiliary materials (thousand straw, shredded grass, thousand cow dung, etc.) in the in-vessel composting process for fermentation, at the same time with fermentation equipment (blender) fully stirring;
Push machine constantly push, to adjust the water and carbon, nitrogen ratio (C/N); The mixed fresh cow dung was fermented for 7 days under suitable temperature and oxygen conditions. Then sent to the dryer, cow dung block and hot air fully contact and quickly lose surface moisture; Because the dryer is equipped with high-speed rotating crushing equipment, the cow dung block is constantly broken, water loss, complete the drying process; Measuring, bagging, packing, warehousing.
Balance in production of composite organic fertilizer, in baking thousand cow dung in the middle of the stage of dry cow dung, the content of N, P, K element and then according to various crops, flowers, grass, fruit, vegetables, and to balance the compound organic fertilizer N, P, K elements, quantitative add in cow dung is drying, using a blender mixing fully, metering, bag filling, packing, the library.
The fermentation method of powder cow dung organic fertilizer production line is as follows:
1. The auxiliary materials such as cow dung, straw, seed and straw, and fermentation agent are piled up in the fermentation site in a fixed proportion.
2. After the composting fermentation temperature rises, the composting can be turned over. When the fermentation temperature is nearly 70 degrees, the windrow composting turner machine should be used to turn over the pile, and the pile should be turned over every other day.
3. When the temperature of compost is reduced, the material is loose, the odor is slightly ammonia, and the white mycelium is produced in the pile, it indicates that the organic fertilizer has been fermented and mature, and the next process can be carried out.
4. Powder cow manure organic fertilizer production line uses forklift truck to transport organic fertilizer to the production workshop, through a series of production processes, made into granular organic fertilizer, and packaged into bags. Iv. Technological process and supporting equipment of cow manure and organic fertilizer production line
The procedure to use cattle dung as a organic fertilizer, such as cow dung, should go through fermentation, crushing, mixing, granulation, screening, drying cooling, packaging and other steps; The equipment used includes organic fertilizer fermentation equipment, forklift truck + feeding bin, semi-wet material crusher, two-axis mixer, organic fertilizer stirring gear granulator, organic fertilizer drying and cooling equipment, roller screen, automatic packaging equipment, other configuration and coating machine, automatic batching system, etc.
The machines for making organic fertilizer in the production line has been relatively mature, which has great advantages compared with the traditional process. For example, the semi-wet material crusher is specially suitable for the crushing of organic fertilizer. After fermentation, it is directly broken, without other equipment and processes. Teeth stirring granulator has many advantages over disk granulator.
The price of the whole production line is determined according to the configuration and different output sizes. We should pay attention to the following aspects in the investment of organic fertilizer factory.
1. Raw materials. The raw materials of organic fertilizer are excrement of poultry and livestock, or some kitchen waste, mushroom residue and so on. Because these raw materials have no other uses, the cost is usually not high. What we need to pay attention to is whether the supply of these raw materials is sufficient. The longer the distance, the higher the transportation cost.
⒉. Electricity cost. For example, small production lines with 80-120 kilowatts can produce about 1 ton per hour.
3. Packaging cost and cost of fermented bacteria. The production line process includes the packaging of organic fertilizer, and the price of different packaging also varies greatly. Please refer to 50 yuan/ton. The fermenting bacteria are also different.
4. Labor costs. A set of production line workers in 4-6 people, of course, different production line configuration needs different numbers of labor, there are automatic packaging machine without workers, there are also semi-automatic packaging machine.
5. Plant and civil construction costs. The process of cow manure to fertilizers has low requirements for the production plant, and there is no need for large-scale construction. The main thing is the cost of the venue. The subsequent plant also need not be greatly adjusted, long service life, calculated to the annual cost is relatively low.
