How Much Does the Cow Dung Organic Fertilizer Production Line?
It is recommended to use aerobic fermentation for the cow manure organic fertilizer production line. It can be fermented with an organic fertilizer starter, which is better for the crop. The cow manure and straw, sawdust, mushroom residue, etc. are in an appropriate ratio (dung accounting for 80-90% , Other accounted for 10-20%) mixed. Add 1 kg of organic fertilizer starter to 1 ton of materials (approximately 2.5 tons of fresh materials), and then add 1 kg of organic fertilizer starter to 5 kg of rice bran (or bran, corn flour and other substitutes) to dilute and then evenly sprinkle into the material pile. During the fermentation process, attention should be paid to proper oxygen supply and stacking, and the temperature is controlled at 55-65°C. The moisture content of the fermented materials should be controlled at 60-65%.
Method of adjusting material moisture: the moisture content of fermented cow dung and other livestock and poultry manure should be controlled at 40-65%. Moisture Judgment: Grasp a handful of cow dung in your hand, see the watermark between your fingers, but do not drip. Fermentation is slow with less water, and aeration is poor with more water. Therefore, we must grasp the moisture content well. If the moisture content is too high, add straw, sawdust, mushroom residue, dry soil powder, etc. Judgment method of whether the moisture is suitable or not: Hold a handful of material tightly, see the watermark between the fingers but not drip, and it will disperse when it hits the ground. The whole fermentation process generally completes the complete deodorization, fermentation maturity, insecticide and sterilization of the materials after 5-7 days.
The start-up temperature of the cow manure organic fertilizer production line technology. The starting temperature should be above 15℃ (operating in four seasons, not affected by the season, try to ferment indoors or in a greenhouse in winter), and the fermentation temperature should be controlled below 70-75℃.
Mix well and ventilate. The production of organic fertilizer by fermentation of cow dung requires good (consumption) oxygen fermentation. Therefore, it is necessary to increase oxygen supply measures during the operation, and it is advisable to mix well, turn frequently, and ventilate. Otherwise, it will cause anaerobic fermentation to produce odor and affect the fertilizer effect.
Fermentation is complete. Generally, after the cow dung has been piled up for 48 hours, the temperature will rise to 50～60℃, and it can reach 65℃ or above on the third day. Under this high temperature, it will be overturned once. Under normal circumstances, there will be two times over 65℃ during the fermentation process. At high temperature, the fermentation can be completed by turning over twice, and the fermentation can be completed within a week. The material was dark brown, and the temperature began to drop to room temperature, indicating that the fermentation was completed.
The production line of small cattle manure organic fertilizer is less than 100,000 dollars. According to the customer’s production scale and capital investment, the organic fertilizer production line configured for each customer is different. The low configuration of the cow dung organic fertilizer production line only requires crushers, mixers, granulators, screening machines and packaging machines. This is a basic configuration, and then add equipment according to the actual needs and requirements of customers. Therefore, the price of the entire cow dung organic fertilizer production line ranges from tens of thousands to hundreds of thousands.
