Processing organic fertilizer by using crop straw

fertilizer granulator Nov 23, 2019

The crop straw organic fertilizer production line advanced composting fermentation process, inoculates high-speed and high-efficiency fermentation bacteria, which makes the straw cellulose rapidly decompose and transform, and all kinds of pathogenic bacteria, weed seeds and aphid eggs are killed, and produce the bio-organic fertilizers with strong stability and full range of nutrient. We combine straw with biological manure and then use organic fertilizer production line equipment for processing. However, the bio-organic fertilizer produced contains a large number of elements such as nitrogen, phosphorus and potassium required for crop growth, and most of them exist in organic form, organic fertilizer. It can not only meet the needs of crop growth, but also improve the ability of crops to adapt to adverse environments.

In order to use crop straw to produce and process organic fertilizer, the scale of design should be determined according to the yield of straw after crop harvesting and fertilizer requirements, and the total amount of crop straw that can be collected.

Straw organic fertilizer production technology and characteristics:
Modern composting is an improved process based on the traditional composting process. It uses organic fertilizer processing equipment and fermenting bacteria to accelerate the composting speed, improve the nitrogen retention capacity, and further process the organic fertilizer production equipment to make the straw organic.Fertilizer efficiency has improved significantly. Because of its good nitrogen fixation effect and good ammoniation, this fertilizer is accompanied by a variety of complex nitrogen-fixing bacteria, which not only has a significant effect on soil improvement, water retention and fertilizer conservation, but also can be widely used in gardening such as flowers, afforestation, inoculum and protected areas.

The main body of the special straw organic fertilizer production line is compost turning machine and organic fertilizer granulator machine. The feed bin of the reaction chamber receives the crushed material of the crop straw, and is uniformly mixed with the yeast and the appropriate amount of water, and then enters the biological digestion reaction chamber for microbial digestion and nitrogen fixation. Treatment, and then enter the microbial fermentation reaction chamber catalytic fermentation to improve fertilizer efficiency, and finally into the heap tank in the microbial fermentation discharge port to be decomposed.

The technology of crop straw composting bio-organic fertilizer is an improved version of the composting production process. The corn straw after harvesting is microbial degraded, fermented and decomposed, and organic fertilizer is prepared by batching, by optimizing the specific environment of the microbial strain. After fermentation, it can be further dried and pulverized as needed, and then the fertilizer granulator machine is used to convert the material into qualified organic fertilizer granule raw materials.

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.

II. Main Technical Parameters of composting

(1). C/N ratio: C/N balance of compost mixture is the key factor for microorganisms to achieve better biological activity. The C/N ratio of compost mixture should be kept at 25-35:1.

(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 granulator machine is the core equipment for fertilizer manufacturing process. As one of leading fertilizer machine manufacturers in China, in addition to the disc granulator, we also produce other types of fertilizer granulator machines, and other equipment such as compost turning machines, mixer machine, crusher machine, etc.
