Working principle: The organic fertilizer rotary drying furnace adopts patented technology and uses the principle of low-temperature hot air for drying. The equipment is equipped with a high-quality heating system and fan system inside, which sends hot air into the equipment through the heating system. Organic fertilizer is dried inside the equipment by rotating, and the fan system helps to circulate hot air, evenly heating the organic fertilizer, accelerating water evaporation, and ultimately achieving the drying effect.

Advantages: The organic fertilizer rotary drying furnace has the advantages of high efficiency, energy conservation, and uniform drying. Compared to traditional high-temperature drying methods, low-temperature hot air drying can retain the nutrients in organic fertilizers to a greater extent and improve product quality. At the same time, the equipment adopts a closed loop operation to reduce the loss of hot air and save energy. In addition, the rotary drying method allows organic fertilizers to be uniformly heated, avoiding the problem of incomplete drying of some organic fertilizers caused by uneven heating in traditional drying equipment.

It should be noted that organic waste such as cow and sheep manure may contain harmful substances such as heavy metals. Therefore, when producing organic fertilizers, it is necessary to pay attention to the safety and quality of raw materials, and conduct necessary testing and control. In addition, in order to improve the quality and efficiency of organic fertilizers, an appropriate amount of additives can be added, such as nutrients such as nitrogen, phosphorus, potassium, and bioactive substances.

The npk manufacturing process can usually be divided into: raw material batching, raw material mixing, raw material granulation, particle drying, particle cooling, particle classification, finished product coating, and final product packaging. The complete set of equipment has less investment, quick effect and good economic benefits. The complete set of equipment has a compact process layout, is scientific and reasonable, saves energy and reduces consumption, and has stable and reliable operation.

In the fertilizer production process, a factor that is not well controlled will affect its organic fertilizer effect. In the field of continuous bulk solids processing equipment, residence time may be one of the most influential variables in process settings, especially in rotary dryers, rotary kilns , rotary drum granulator, or other types of drums when processing materials.

Residence time is the amount of time a material is processed in a given facility. In most process settings, a specific retention time must be able to be achieved to achieve its intended goal. For example, the need to achieve a specific moisture content, initiate or complete a chemical reaction or phase transition, form particles within a desired particle size distribution, etc.

For example, in terms of quality, a spin dryer without a proper understanding of the retention time can cause the material to reach the target moisture level prematurely in the drum, meaning the material will continue to dry for the remainder of the time. This can cause the material to overdry and break down into fine powder. Likewise, if the drum is not long enough to accommodate the necessary retention time, the material may exit the drum before reaching the desired moisture content, still not reaching the desired target particle size. In other cases, the quality may not be compromised, but the drum size may be too large, resulting in reduced efficiency. Therefore, in the production process of the npk fertilizer production line, it is necessary to control the time rhythm and pay more attention to the temperature, humidity, size and shape of the material.

The production process of organic fertilizer mainly includes steps such as raw material treatment, fermentation, dehydration, crushing, screening, and packaging.

Firstly, raw material processing is a very important step. The main raw materials for organic fertilizer include animal manure, plant straw, and fruit peel. These raw materials need to be cleaned and crushed for better fermentation.

Next is the fermentation stage. Mix the processed raw materials with microbial strains and place them in the compost yard for fermentation using an organic fertilizer turner. During the fermentation process, microbial strains will decompose organic matter, produce organic acids, ammonia and other substances, and release and stabilize nutrients in organic fertilizers.

Then comes the dehydration step. After fermentation, organic fertilizer will have a certain moisture content. In order to improve the quality of organic fertilizer and facilitate storage and transportation, it needs to be dehydrated. Typically, equipment such as centrifuges and filter presses are used for dehydration to reduce the moisture content of organic fertilizers.

Next is fragmentation and screening. The dehydrated organic fertilizer needs to be crushed using an organic fertilizer crusher to make the particles finer and improve the nutrient release efficiency. At the same time, screening is also necessary to remove impurities and ensure the purity and quality of organic fertilizers.

Finally, there is the packaging process. The organic fertilizer processed through the above steps will be packaged as needed for easy storage and sales.

The above is the main process flow of the organic fertilizer production line, and each step is very important. It is necessary to strictly control the quality and operational requirements of each link in order to produce high-quality organic fertilizer products.

The supporting equipment for small-scale organic fertilizer production lines mainly includes:

Fermentation tipping machine: used to evenly stack materials, increase the contact area between materials and air, and promote the fermentation process.

Crusher: The fermented material is crushed for subsequent granulation and packaging.

Fertilizer mixer: Mix and stir the crushed materials to ensure their uniformity.

Fertilizer granulator: Granulates the mixed material to form the desired shape of particles.

Drying machine: Drying the granulated particles to reduce moisture content and improve particle stability.

Cooling machine: Cools the dried particles to a suitable temperature and humidity.

Screening machine: screens the cooled particles to remove particles that do not meet the requirements.

Packaging machine: Packaging qualified particles after screening for storage and transportation.

The quotation for a complete set of organic fertilizer processing equipment is generally between 200000 and 5 million depending on the configuration. The specific quotation needs to be compared with the actual needs and the manufacturer’s quotation to select the most suitable equipment configuration scheme. It is recommended to understand the market situation and manufacturer’s strength before purchasing, in order to better choose the equipment that suits oneself.

Livestock and poultry manure contains a large amount of nitrogen, phosphorus and other substances, which will not only pollute the surface water, but also pollute the groundwater if it penetrates into the ground, which has a great impact. Once the water is rich in a large amount of nitrogen and phosphorus, it will lead to eutrophication of the water quality, and aquatic plants such as algae will grow in large quantities, robbing aquatic organisms for oxygen, resulting in hypoxia in the water, resulting in the death of a large number of aquatic organisms.

How much do you know about automatic packaging machines and what are the advantages of automatic packaging machines?

Automatic packing machine, this equipment is a fully automatic quantitative packaging machine (including transportation, sewing machine, heat sealing machine, etc. ) and optional parts (transportation equipment, sewing machine, heat sealing machine).

Working principle of automatic packaging machine:

The material is fed into the weighing hopper by the feeding part (pneumatic valve). After the controller receives the weight signal from the sensor, it works according to the preset program value. Fast feeding at the beginning, when the weight is close to the target value, the fast feeding door will automatically stop; when entering the middle feeding, when the weight is almost the same as the target value, the intermediate feeding door will automatically stop; when entering the slow feeding; when the weight is consistent with the target value, Automatically stop the slow feed gate, and all feed gates are fully closed.

Main features of automatic packaging machine:

Then how long does the material stay in the equipment (rotary drum granulator) to achieve the desired quality, the residence time is the amount of time the material is processed in a given equipment. In most npk manufacturing process setups, producers must be able to achieve specific retention times to achieve their desired goals.

While retention time looks simple in theory, it gets complicated when a continuous process is used. In a continuous production run, there are no batches, and there is no real boundary between “start” and “end”; material is constantly entering and exiting the drum at the same time, making it difficult to determine the true length of time to process a given portion of material.

1. Introduction to Tracers

Tracers such as dyes or chemicals are not always permitted due to product composition or contamination concerns. However, where permitted, the tracer can be a very useful tool for determining retention times; by measuring where the tracer begins to flow out of the drum and where the tracer is no longer seen, the average retention can be determined time.

2. Measure drum volume

The retention time can also be defined by measuring the volume of material in the drum or the weight of the material in the drum when the process is at steady state. In steady state, the material is fed and discharged at the same rate. The average retention time can be determined by dividing the material bed volume or material bed weight by the volumetric flow or mass flow. It is important to understand that retention times are always averaged across consecutive settings.
