Organic fertilizer production line with an annual output of 50,000 tons

At present, the organic fertilizer production line is divided into three grades of complete sets of organic fertilizer production line equipment according to production capacity: large, medium and small. The cow dung organic fertilizer production line with an annual output of 50,000 tons is a medium-sized organic fertilizer production line.

At present, more than 75% of the small organic fertilizer production lines in the market are less than 20,000 tons, or even ultra-small organic fertilizer production lines of less than 10,000 tons. Some small family-style organic fertilizer production lines have poor equipment, or the production line simplifies the process without permission, resulting in insufficient fermentation of organic fertilizer in the fermentation stage, or unreasonable selection of raw materials and ingredients, resulting in substandard nutrients, or with local soil trace elements. conflict.

This is also the main reason why organic fertilizer equipment manufacturers often recommend medium-sized organic fertilizer production lines. The medium-sized organic fertilizer production line refers to the production line with an annual output of 30,000-70,000 tons.

The process flow of the cow dung organic fertilizer production line with an annual output of 50,000 tons is:

Fermentation of cow dung → the fully fermented raw materials are turned by the turner → pulverizer pulverization → screening machine → automatic batching system → double shaft pulverizer pulverization → granulator granulation → dryer drying → dust collector dust removal → cooler Cooling→dust removal→cooling→coating machine coating→screening machine screening→automatic packaging machine packaging→finished product storage.

The cow dung organic fertilizer production line with an annual output of 50,000 tons has a high degree of automation, round granulation, sufficient fermentation, and high product qualification rate. It is the preferred plan for investing in large and medium-sized organic fertilizer processing.

For the cow dung organic fertilizer production line, it is recommended to use aerobic fermentation treatment, which can be fermented with a starter, which is better for crops. The cow dung is mixed with straw, sawdust, mushroom residue, etc. in an appropriate proportion (feces account for 80-90%, Others account for 10-20%) mixed. 1 ton of material (about 2.5 tons of fresh material) is added with 1 kg of fertilizer starter, diluted by 1 kg of fertilizer starter and 5 kg of rice bran (or bran, corn flour and other substitutes), and then evenly sprinkled into the material pile. During the fermentation process, pay attention to proper oxygen supply and turn over, and the temperature is controlled at 55-65 °C. The moisture content of the fermentation material should be controlled at 60-65%.

Fermentation skills of cow dung organic fertilizer production line:

Method for adjusting the moisture content of materials: the moisture content of fermented cow dung and other livestock and poultry manures should be controlled at 40-65%. Judgment of moisture content: Grab a handful of cow dung tightly, see watermarks between your fingers but not dripping water, and it is advisable to disperse when you land. Less water leads to slower fermentation, and more water leads to poor ventilation. Therefore, we must grasp the moisture content. If the water is too high, straw, sawdust, mushroom residue, dry soil powder, etc. can be added. How to judge whether the moisture is suitable or not: Grasp a handful of materials tightly, see the watermark between the fingers but not dripping, and it will disperse when it falls. The entire fermentation process generally takes 5-7 days to complete the complete deodorization, fermentation and decomposing, and insecticidal sterilization of the material.

The technical start-up temperature of cow dung production organic fertilizer production line. The starting temperature should be above 15°C (it can be operated 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°C.

Mix and ventilate. The production of organic fertilizer by cow dung fermentation requires good (consumption) oxygen fermentation. Therefore, in the process of operation, it is necessary to increase the oxygen supply measures, so that it is advisable to mix well, turn frequently, and ventilate. Otherwise, it will lead to anaerobic fermentation and produce odor, which will affect the effect of fertilizer.

Fermentation is complete. Generally, after 48 hours of accumulation of cow dung, the temperature rises to 50 to 60 °C, and it can reach above 65 °C in three days. At this high temperature, it is turned over once. Under normal circumstances, there will be two high temperatures above 65 °C during the fermentation process. , the fermentation can be completed by inverting it twice, and the fermentation can be completed within a week normally. The material is dark brown, and the temperature begins to drop to room temperature, indicating that the fermentation is complete.

Complete configuration of cow dung organic fertilizer production line with an annual output of 50,000 tons:

The two-in-one granulator with an annual output of 50,000 tons of cow dung medium-sized organic fertilizer production line is composed of a body part, a granulating rotor part and a transmission part. It is a particularly important part of the complete set of equipment for this series of organic fertilizer production lines.

The working principle is: the material enters the machine from the feeding port at one end of the body, and is continuously pushed by the granulating rotor and mechanically moves with the casing to achieve the purpose of granulation, and the finished granules are pushed out of the machine at the other end of the body. The rotor is driven by the motor and reducer of the transmission part, and the transmission part and the body part are mostly fixed on the same frame, so that not only the structure is firm, the operation is stable, but also the installation is very convenient.

In addition to granulation equipment, other ancillary equipment includes turners, pulverizers, dryers, screening machines, mixers, coating machines, packaging machines, conveyors, etc.
