Fermentation Mode of Chicken Manure Organic Fertilizer Manufacturing Process

fertilizer granulator Nov 19, 2019

Organic fertilizer, commonly known as farm manure, consists of various animal, plant residues or metabolites, such as human and animal manure, straw, animal residues, slaughterhouse waste, etc. Carbon-containing materials, mainly from plants and animals, are applied to the soil to provide plant nutrition as its main function. It not only provides comprehensive nutrition for crops, but also has long fertilizer efficiency. It can increase and renew soil organic matter, promote microbial reproduction, improve soil physical and chemical properties and biological activity. It is the main nutrient in green food production.

The production of organic fertilizer must go through composting fermentation process. Composting is a process in which organic matter is continuously degraded and stabilized by microorganisms under certain conditions, and a product suitable for land use is produced.

Site selection

The site should be flat, near the water source and sunny from the leeward. It does not pollute the environment and is easy to provide water.

Chicken Manure Organic Fertilizer Fermentation Mode

1. Store the materials and add the bacteria proportionally. Water content should be controlled at 60%-70%. Fermentation of less water is slow and aeration of more water is poor. Oxygen deficiency will corrupt and produce odor.

2. The start-up temperature is better than 15℃ (can be operated in four seasons, not affected by season, fermentation in indoor or greenhouse in winter as far as possible), and the fermentation temperature should be controlled between 60 ~65℃.

3. Fermentation of organic fertilizer needs oxygen consumption fermentation. In the process of operation, oxygen supply measures should be increased so as to mix well, turn over frequently and ventilate properly. The windrow turnercan work accurately to meet the requirements, it’s an important equipment of fertilizer fermention. Windrow compost turning machine has the advantage of high efficiency, smooth operation, strong and durable, even turning throw.
4. Fermentation

Warming-up stage: generally only one day is needed from room temperature to 50℃.

High temperature stage: generally only 2 days from 50-70℃.

Cooling stage: from high temperature to below 50℃, generally about two weeks. The temperature began to drop to normal temperature, indicating that the fermentation was completed.

FAQ of Organic Fertilizer Fermentation:

1. Slow warming: no or slow warming of the reactor

Material is too wet, too dry, there is not enough nitrogen source, and the pH is too low.

2. Heap temperature is too high: during fermentation, the heap temperature is more than 65℃.

Poor permeability.

3. Odor: The odor of rotten eggs or rotten eggs is emitted from the stack.

Ammonia content is too high, material stacking is too dense.

After being processed by the chicken manure organic fertilizer production equipment, these organic fertilizers can be sold. Huaqiang fertilizer machine manufacturer supply professional organic fertilizer production line, and a series comprehensive service.

What is the reason that the compost turner machine is used for manure composting?

fertilizer granulator Nov 19, 2019

As a new type of compost turner machine, Double-screws Turning Machine is widely used in animal manure organic fertilizer production and bio-organic fertilizer production. It is the core equipment of aerobic dynamic composting, and it is based on the organic Fertilizer manufacturing process and NPK fertilizer production machinery equipment family. The unique mechanical design and practical mechanical properties are rapidly multiplying, and it is the best substitute for replacing the manual and forklift materials. It is the mainstream product of the pre-fermentation application of organic fertilizer production line and biofertilizer project.

The Double-screws Turning Machine comprises a traverse device, a traveling device and a tumbling device, wherein the tumbling device comprises two reducers fixed to the frame, a screw shaft connected to the respective reducer via a coupling member and fixed with a spiral blade. When the device is walking on a specific track, the screw shaft will no longer work, and the screw shaft will automatically rotate to move against the work when walking to the effective work surface. The fermentation rate is increased, the compost is rapidly decomposed, the odor is prevented from being generated, and the fermentation time is shortened.
Double-screws Turning Machine performance characteristics:

1. Fully stir the doping to make the material meet the granulation demand quickly.
2. Due to the large stacking force, the material is supplemented with more fresh air, which helps the aerobic microbial fermentation to heat up, and constitutes a process of high-temperature exchange, which helps all kinds of beneficial micro-bacteria to develop and multiply in the temperature range where it adapts.
3. The turner system can process the material into small clumps, making the thick and dense material pile loose and elastic, and forming a suitable porosity.
4. After the raw materials are turned over and fermented, there is certain water content. The consumption of raw materials by a large amount of microorganisms generated after turning over the piles will also release the water in the carrier. Therefore, as the fertilizer process reduces water, in addition to the evaporation of the heat transfer composition, the turning machine flips the raw materials to form a forced water vapor volatilization.
5. Achieve special requirements for the composting process. For example, the breaking of the raw material, the shape of the raw material pile or the quantitative shift of the raw material is achieved. As one of the important equipments in the fermentation equipment and organic fertilizer production process, the turner has been at the forefront of the development of the times, making great contributions to the organic fertilizer production line andbiofertilizer project.

(2). Humidity: Aerobic composting should generally be maintained at 40-70%.

(3). Acidity and alkalinity: Acidity and alkalinity vary with the types of compost mixtures and different stages of composting process. Normally, they need not be regulated. If they need to be regulated, they can be regulated by adding alkaline or acidic substances to the mixture before the beginning of composting degradation.

(4). Other design parameters: Rectangular fermentation stacking composting mode, the windrow turner should be used regularly to turn the pile, so that the temperature is kept below 75℃, and the turning frequency is 2-10 days/time. The width and depth of rectangular stacks are limited only by the overturning equipment. The stacks are generally 1.2-1.8 meters deep and 1.8-3 meters wide. The height of the compost is usually 2.5-4.5 meters, and the width is usually twice the depth. Fermentation tank composting, need to build fermentation tank, fermentation tank length is unlimited.

III. Matters needing attention in composting

(1). Composting time: Composting time varies with C/N ratio, humidity, weather conditions, type of composting operation and management, waste and additives. The composting time of well-managed strip-cutting fermentation compost in summer is generally 14-30 days.

(2). Temperature: We should pay attention to the monitoring of composting temperature. The composting temperature should exceed 55℃, so as to be conducive to microbial fermentation and kill pathogens.

(3). Humidity: Pay attention to monitoring the humidity of compost mixture periodically. Excessive or low humidity will reduce or stop the composting speed.

(4). Odor: Odor is a good indicator of composting operation stage. Decay odor may mean that compost is changed from aerobic to anaerobic.

The working principle of the disc granulator in the fertilizer production line

fertilizer granulator Nov 19, 2019

The disc granulator machine is mainly used in the NPK fertilizer production line and organic fertilizer production line to produce various granular products; it’s also used in pharmaceutical products, fertilizers, feeds, etc. Adopting the overall arc structure, the granulation rate can reach above 93%. The granulation tray has three discharge ports, which facilitates intermittent production operations, greatly reduces labor intensity and improves labor efficiency.

Disc fertilizer granulator machine working principle:
The raw meal powder is uniformly wetted by the atomized water in the mixer to form a spherical core having a uniform particle size, and then fed into a ball plate for ball formation. The moisture of the ball should be controlled at 12-14%. Most of the water should be added in the twin-shaft mixer. Only a small amount of supplementary water is added to the ball plate, and the amount of water added is controlled to be about 0 to 3%. The dry powder granulation is directly added to the ball-forming plate, and the proper amount of water is sprayed. The raw material nucleus enters the spherical disk and is subjected to centrifugal force, friction and gravity in the disk, and moves along the parabola. Due to the cohesiveness and plasticity of the material, the cores are bonded to each other and gradually grow up during the movement. When the inclination angle of the ball disc, the height of the disc edge, the rotation speed and the moisture are constant, the balls of different particle sizes roll downward from the edge of the disc at different disengagement angles due to different gravity. During the continuous rolling process, the ball continuously discharges the water in the ball out of the surface. Due to the cohesiveness of the material and the natural volatilization of the surface liquid film, the ball has certain strength, and then the disk is rotated with the tilting of the disk. The sides are discharged out of the pan.

Disc granulator performance advantages:
1. The raw materials are suitable for a wide range of applications. They can be used for granulation of various raw materials such as compound fertilizer, medicine, chemical feed, coal, metallurgy, etc., and can produce various concentrations and various types (including organic fertilizer, inorganic fertilizer, and magnetic fertilizer etc.) of compound fertilizer.
2. The disc granulator is light in weight, low in height, and flexible in process;
3. The machine has simple structure, convenient adjustment and superior performance.
4. The use of unique unpowered combination scraper integration reduces auxiliary power consumption.

5, high ball formation rate, large rounded particle strength, intuitive operation, easy maintenance and so on.

Fertilizer equipment

fertilizer granulator Nov 15, 2019

Fertilizer  equipment plays an extremely important role in the production process of fertilizer. In the era of advocating organic cultivation, it is an important step for investors who want to invest in the organic fertilizer market to choose appropriate organic fertilizer equipment. Here, we can understand the concept of different organic fertilizers, and then understand the different process modes that can be used for the production of commercial organic fertilizers, the production of organic fertilizers under the conditions of planting and breeding mode, and the production of organic fertilizers in small-scale farms, as well as how to select the appropriate biological fertilizer production equipment under various modes.

1. Organic fertilizer raw materials

According to the different raw materials and processing technology of organic fertilizer, it can be roughly divided into compost, retting, manure, biogas fertilizer, green fertilizer, straw fertilizer and other organic fertilizers. Compost refers to a kind of organic fertilizer, which is composed of crop straw, manure and animal carcasses, rice husk, grass and a small amount of soil. The difference between retting and composting is the organic manure which is produced by fermentation under the condition of flooding, and the raw materials used are the same as compost. The raw materials used for the manure are the manure of livestock and poultry and the bedding materials in the shed, which are made of compost. The raw material of biogas fertilizer is the same as that of compost. The process is the residual biogas liquid and residue after biogas production by anaerobic fermentation, which is the by-product after biogas production. Green manure uses green plants as fertilizer. Straw fertilizer raw materials include corn, rice and other crop straws. Under suitable conditions, through the role of soil microorganisms, the elements in straw are mineralized back to the soil and re absorbed by crops. There are other organic fertilizers, such as cake, sludge and so on, which can be processed into organic fertilizer through the organic fertilizer production equipment.

3. Organic fertilizer production equipment

The complete organic fertilizer production line is composed of a variety of organic fertilizer equipment. The key equipment is fermentation reactor and organic fertilizer granulator, which are divided into raw material preparation stage and finished product processing stage.

Organic fertilizer granulator

In the whole organic fertilizer manufacturing process, the organic fertilizer granulator plays an important role in the fertilizer production equipment. The raw materials of organic fertilizer change in this link and become commercial organic fertilizer. The quality and output of organic fertilizer particles are important embodiment here. Organic fertilizer particles are formed by binding organic fertilizer raw materials together with water as binder, and the amount of water directly affects the production efficiency. Theoretically speaking, in the mixing process of the mixer in front of the organic fertilizer granulator, if the amount of water added is small, the viscosity of the powder will be small and the particles produced will be very small; otherwise, if the amount of water added is large, the viscosity of the powder will be large and the particles produced will be very large. Of course, this also leaves us a lot of choices. We can choose the appropriate particle size of organic fertilizer according to the needs to meet the market demand.

These fertilizer machines not only can be used in the organic fertilizer production line,it also can be used in the bio fertilizer production line or npk fertilizer production line to produce the bio organic fertilizer granulator or npk,compound fertilizer.

Bio-organic fertilizer refers to a kind of fertilizer with microbial fertilizer and organic fertilizer effect, which is composed of animal manure as the main raw material, inoculated with microbial compound microbial agent, fermented and decomposed to completely kill pathogens, insects and eggs, etc. Biofertilizers generally contain a large number of elements such as nitrogen, phosphorus and potassium, and trace elements such as calcium, magnesium, sulfur, iron and boron, as well as a large number of organic and humic acid substances, so that the fertilizer supply is balanced. The bio-organic fertilizer production line processes the fermented materials into the final organic fertilizer.

Raw materials for organic fertilizer production equipment

The main raw materials for biofertilizer production are livestock manure, crop straw and other agricultural wastes.

Mixed ingredients for organic fertilizer production

The source of raw materials, fermentation methods and equipment are different, and the ingredients are different. The specific formula depends on the source of organic materials. The general principle of proportioning is that the content of organic matter in the total material should be more than 30% (50% – 70% is the best), the ratio of carbon to nitrogen (15:1) – (20:1), the pH value should be 6-7.5, the moisture content should be about 50%, and the water content should be adjusted to 50% – 70% when inoculated.

Fermented maturity

It can be stacked flat or fermented in a fermentation tank. Fermentation tanks are usually placed in closed or semi-closed fermentation chambers. The effect is better than that on flat ground. It needs to be turned periodically by the fertilizer turner machine every three days. After 25-30 days of fermentation, the temperature gradually decreases from 70-80℃ to stable, and the decomposition is completed.

Organic fertilizer production equipment and process flow

How to select fertilizer granulator suitable for compound fertilizer production

fertilizer granulator Nov 13, 2019

Solid compound fertilizer granules are more effective than other fertilizers in use and soil, and are widely welcomed in the market. Fertilizer granulation is a basic treatment method in fertilizer production. Fertilizer granulator machine mixes different fertilizers into granules, which plays an important role in NPK fertilizer production line.

Basic fertilizers such as ammonium bicarbonate, urea, ammonium chloride, ammonium nitrate, ammonium sulfate, ordinary superphosphate, calcium magnesium phosphate, ingot phosphate, heavy superphosphate, potassium chloride, potassium sulfate, phosphate nitrate, dicalcium phosphate, potassium nitrate and so on are proportionally compounded to make the compound fertilizer we need, which is granulated by fertilizer granulator. Granulation is the granulation of fertilizer containing water. In NPK fertilizer production equipment, the commonly used fertilizer granulator machine includes double roller fertilizer granulator, rotary drum granulator and disc fertilizer granulator.

Fertilizer granulator machine granulates by agglomeration

The working principle of drum granulator and disc granulator is similar. When urea, calcium superphosphate, ammonium sulfate, ammonium phosphate, ammonium nitrate, potassium fertilizer and other fertilizers are mixed, they are aggregated into compound fertilizer granules through granulation operation. Rotary drum granulator and disc granulator are suitable for granulation of various ingredients, and the obtained granules are of good quality and high granulation rate of materials.

The main body of the rotary drum granulator is a horizontal drum. The drum is driven by motor, reducer and gear, which is supported by wheel and rollover. The drum granulator has strong production capacity, long material residence time and good granulation effect.

The main body of the disc granulator is a slightly inclined disc, which continuously rolls to complete granulation. In the production of disc fertilizer granulator, the production situation can be seen directly, which is convenient to observe and adjust in time, and the granulation rate of compound fertilizer is high.

Fertilizer granulator machine granulates by extrusion

The double roller fertilizer granulator makes the material into granules by extrusion method. The water content is not higher than 15%, and the materials with good fertilizer effect are mixed after mixing, and the material is strongly extruded by the roller press granulator, so that the molecular force between fertilizers acts and is extruded, and then the sheeted material is crushed into granular compound fertilizer.
