Structural analysis of fertilizer pellet making machine

A fertilizer pellet making machine is a molding machine that can make materials into specific shapes. The wet tooth fertilizer pellet making machine uses the mechanical stirring force of high-speed rotation and the resulting aerodynamic force to continuously realize the process of mixing, granulation, spheroidization, and densification of fine powder materials in the machine, so as to achieve the purpose of granulation.

This organic fertilizer pellet making machine granulation method makes the granulation rate higher, the granules are more beautiful, and at the same time saves energy and is highly energy-efficient.

1. Structural analysis of fertilizer pellet making machine

  • The main structure of the fertilizer pellet making machine is an inclined rotating cylinder, and the drive can be constant speed or variable speed. When the liquid content of the feed powder is suitable, agglomeration occurs and tumbles in the drum.
  • The drum has a certain slope, and the included angle between its axis and the horizontal is less than 10º, which can help the material to roll along the length of the drum, and a baffle ring is often installed at the feeding end to prevent the material from flowing back.
  •  A retaining ring can also be installed at the discharge end to increase the thickness of the material layer and prolong the residence time in the main drum. Sometimes the cylindrical screen is integrated with the rotating drum to form a product discharge port.
  • The feeding of the fertilizer pellet making machine is composed of fresh material and circulating material, and the feeding system can adopt belt conveyor, chute pipeline or other similar equipment. The binding liquid is injected either before the solid material enters the rotary cylinder, or immediately after the solids enter the rotary cylinder.
  • Like the disc fertilizer pellet making machine, the inner surface structure of the drum plays an important role in whether the material can react well in the drum. Inside the steel drum, general shirts have heat-expandable metal.
  •  The function of various internal scrapers is to maintain a certain thickness of the material on the inner surface of the drum, so that the material layer is uniform, and it is convenient for the material to roll and turn normally in the drum. Rubber baffles and liners as well as external shocks are used to prevent build-up during fertilizer granulation.

2. Moisture control of fertilizer pellet making machine

In the drum granulation, the coarsening of the pellets is mainly based on the cladding type, so the amount of material circulation should be larger, so this can provide a coarser core for the cladding process, and the water injection amount should be smaller, so that The water absorption of the core can be made less.

When granulating by bonding or “aggregation”, the material marriage is smaller than it should be because the material in the drum is mainly composed of fresh raw materials with small particle size and mutual bonding. The liquid ratio required for bonding should be large, because the gaps between the mutually bonded fine powder particles need to be filled with water.

Due to the deepening of the understanding of the granulation process, some suitable monitoring instruments have been developed, so that it is possible to simulate and automate the computer control of the granulation process.

3. Comparison of granulation systems

In order to make the right choice between the disc granulation system and the drum granulation system, a quantitative comparison of the two methods was made.

In the same workshop, when the fertilizer pellet making machine granulation process, process raw materials and monitoring conditions are the same, two processes are used for granulation at the same time, and the following conclusions are drawn from the comparison:

① The capital construction investment of the two fertilizer pellet making machine processes is roughly equal;

②The construction space of the disc granulation process is about 10% less;

③ The physical labor of the two processes is approximately equal;

④ The power consumption of the disc granulation system is high;

⑤ The noise of the disc granulation system is low;

⑥ The disc fertilizer pellet making machine needs less product and smaller equipment;

⑦ From the point of view of product quality, the two processes are not different.

From the perspective of the cost of granulation, combining the above four items, the disc granulation system is only 2% lower than the drum granulation system. Such a small difference prevents us from making a simple choice between the two.

According to the actual production needs, you can refer to the following methods to choose:

  • The disc fertilizer pellet making machine has the characteristics of automatic classification, small footprint, low cost, zero operation, and easy observation. Therefore, it can be used to guide the granulation process for a wide variety of material types with precise agglomerates.
  • Drum granulation has the characteristics of large production capacity, long logistics retention time, and multiple simultaneous processes. Therefore, it is suitable for the granulation of materials that are not easy to be granulated, and is suitable for mass production.

Influence of floating fish feed pellet making machine

Although the application of floating fish feed pellet making machine extrusion technology in the feed industry started late, the development speed is very fast, and the application range is also relatively wide, and it has even become an important technical means in the current feed processing.

However, how to use the extrusion technology and floating fish feed pellet making machine scientifically, rationally, and stably for a long time to maximize its benefits and functions is still a technical problem that puzzles many feed companies.

1. The influence of floating feed extruder machine

(1) Influence of extrusion on starch

The starch in the feed is mainly amylose, and because the starch pellets form granular agglomerates, its structure is compact and the water absorption is poor. The starch enters the extruder from the floating fish feed making machine conditioner, and in the closed environment of high temperature and high pressure, the macromolecular polymer is in a molten state, and the local molecular chain is cut off by strong pressure and shearing force, resulting in the degradation of amylopectin.

 At the same time, it also causes the cleavage of the α-1,4 glycosidic bond in the amylose, resulting in starch dextrinization, and the starch molecules are broken into short-chain dextrins, which are degraded into soluble reducing sugars, which improve the solubility, digestibility and flavor of starch.

The extruded starch made by floating fish feed pellet making machine, not only has gelatinization effect, but also saccharification effect, which increases the water-soluble content of starch several times to dozens of times, provides favorable conditions for the action of enzymes, and improves the utilization rate of starch in aquatic feed. .

(2) The effect of extrusion on protein

During the floating fish feed pellet making machine extrusion process, the protein is subjected to high temperature, high pressure and strong mechanical shearing force in the extrusion cavity, its surface charge is redistributed and tends to be uniform, the molecular structure is stretched and reorganized, and the intermolecular hydrogen bonds,

Secondary bonds such as disulfide bonds are partially broken, resulting in the final denaturation of the protein. This denaturation makes it easier for proteases to enter the interior of the protein, thereby improving digestibility.

 In the floating fish feed pellet making machine extrusion process, the main factors affecting protein denaturation are temperature, pressure, strong shear and the moisture of the extruded material.

(3) The effect of extrusion on fat

The inactivation of lipase and lipoxygenase in the feed improves the storage stability of fat, and also promotes the formation of fat-starch complexes and reduces fat deterioration, which is beneficial for fat storage.

 Full-fat soybeans are puffed to reduce the chance of fat being exposed to air and deteriorate. In a high-shear environment, soybean oil cells are fully ruptured, thus improving the utilization of fat. Under mild conditions, such as the floating fish feed pellet making machine puffing temperature below 100℃, the effect of fat oxidation is small.

As the floating fish feed making machine puffing temperature rises from 120℃ to 170℃, the moisture increases, and the residual time in the extrusion cavity increases, and the fat oxidation value increases rapidly.

In addition, there are other factors affecting the oxidation of fat, such as the increase of product surface area and transition metal elements can accelerate the oxidation of fat.

(4) Influence of extrusion on crude fiber

Crude fiber feed, also known as rough feed, refers to feed with a natural moisture content below 60% and a crude fiber content equal to or higher than 18% in dry matter. The crude fiber content in all kinds of straws is more than 20%, and the crude fiber content in rice husk is 44%, which is the grain by-product with the highest crude fiber content in all feeds.

 The annual output of various types of straw in my country is 5 trillion tons, and the part used for feed is less than 10%. Compared with the utilization rate of 20% in developed countries, there is a big gap .

Through the floating fish feed pellet making machine extrusion technology, due to the humidification, heating, pressurization and expansion, the lignin between cells and the layers in the cell wall is melted, some hydrogen bonds are broken, the crystallinity is reduced, and the macromolecular substances are decomposed.

The original compact structure becomes fluffy and part of the digestible substances are released, thereby improving the utilization rate of the feed. The current research results show that after the fibers are processed and extruded, the content of soluble fibers increases relatively, generally by about 3%.

The fiber change is mainly affected by the floating fish feed pellet making machine processing conditions, and obvious changes will occur when the processing conditions are severe.

(5) Influence of extrusion on vitamin.

The high temperature, high humidity and high pressure of the floating fish feed pellet making machine puffing process will lead to the loss of the biological activity of various vitamins, among which the vitamins that are easily oxidized are particularly obvious.

The vitamins added or added to the feed are all lost due to extrusion processing of floating fish feed extruder. The way to overcome the loss of vitamin activity caused by puffing is to increase the amount of vitamins added to the formula, so that the lost residual vitamins can still meet the needs of animals.

(6) The impact of extrusion on harmful substances

The extrusion process of floating fish feed pellet making machine can not only effectively reduce the anti-nutritional factors in the feed such as antitrypsin, lipoxygenase, aringoxin, etc., but also decompose the mustard II and Gossypol, reducing the content of its harmful components.

 In addition, for common harmful microorganisms in feed raw materials, such as Escherichia coli, Salmonella, etc., most of the harmful microorganisms can be killed by extrusion.

2. Biomass pellets vs coal

biomass pellet mill for sale

It is still a common practice for factories to use boilers for production. This type of boiler equipment needs fuel to operate, and the fuel that can meet the needs of equipment operation, the market mainly provides two options, one is traditional coal fuel, the second is It is pellet fuel processed by biomass fuel pellets. After testing by biomass fuel pellet manufacturers, the two fuels are significantly different, which will have very different effects on the party who uses the fuel.

(1)Burning speed and time

The combustion speed of pellet fuel made by biomass pellet mill mainly depends on the volatile content of the fuel, and the combustion time is closely related to the density. After the test of biomass fuel pellet manufacturers, traditional coal cannot compare with pellet fuel in these two factors. Therefore, pellet fuel is clearly better than coal in terms of the direct requirement of using boilers.

(2)Availability of Burning Ashes

After the coal is burned, the remaining ash does not actually have any effect, but will pollute the surrounding environment, but the pellet fuel made by biomass pellet mill is different. It will cause damage to the environment and can become an organic potash fertilizer.

(3)The corrosiveness of fuel

According to the test, coal itself is quite corrosive, so if the fuel is used for a long time, the boiler will inevitably form more wear and tear. The advantage of pellet fuel made by biomass pellet mill is that it does not contain sulfur and phosphorus, which can help the operation of the boiler at the same time. Boiler has a negative impact.

In general, after the above test results, biomass fuel pellet manufacturers believe that pellets are the fuel that persists and can bring positive effects to users, and the country also actively calls on factories that use boilers to use pellet fuels instead of coal.

2. Biomass fuel pellet machine for waste crops

The biomass pellet mill can properly process waste wood chips and straws into biomass fuel. The biomass fuel has low ash, sulfur and nitrogen content. Indirect substitution of coal, oil, electricity, natural gas and other energy sources.

It is foreseeable that this environmentally friendly biomass pellet machine can effectively treat the remaining waste crops such as waste sawdust and straw, and also produce non-polluting new energy. my country’s atmospheric governance has played a very important role in environmental protection.

biomass pellet mill is mainly aimed at waste wood chips and straw, and these two types of materials are also the most produced in our country and are in urgent need of treatment, construction waste, domestic waste, and the furniture industry will produce a large amount of waste wood at all times. If these waste wood are directly discarded, it will pollute the environment and waste renewable resources.

There is also straw. A large amount of straw is produced every autumn. In the past, ordinary people directly burned the straw, which not only wastes resources, but also greatly pollutes the environment.

The disposal of crop straw is also a problem that the country and local governments have been concerned about. In this case, a device that can process wood chips and straws and turn waste into treasure is particularly important, and the importance of biomass pellet mill at this time is revealed.

The peeling machine breaks the shortcomings of the traditional drum-type wood peeling machine, which has to be stopped for discharging and feeding.

The veneer outlet and the wood outlet are separated to realize continuous work, and the whole process from feeding → peeling → wood output → re-feeding → re-peeling → wood output is continuous, and the flow operation is realized. Relative to different wood species, the peeling effect can be adjusted, and the wood can be peeled on the machine for different lengths, bends, and wetness. The single-machine trough peeling machine can peel 35-50 tons of logs a day, which greatly saves manpower.

Features of wood peeling machine:

 ①Using an open silo, which can be fed from one end and discharged from the other end, overcomes the shortcomings of the existing drum peeling machine for feeding, discharging, and segmented work, and has high work efficiency.

 ②Due to the impact of the teeth on the wood segment, the wood segment not only makes a circular motion in the casing, but also rotates around itself, so the peeling efficiency is high, and the tree species that are difficult to peel such as eucalyptus poplar have a better peeling rate

 ③The peeling machine has strong adaptability to wood, and can peel wood segments of different tree species, diameters, lengths and shapes. Because the wood segments perform rotary motion and irregular beating, the concave part of the curved wood segment can also be very similar to the peeling teeth. Nice touch. Therefore, the stripping rate for curved logs is much higher than other drum types.

 ④Because the huge casing is fixed, so the energy consumption is low, the failure rate is low, the maintenance workload is small, and the vibration and noise are much lower than that of the drum peeling machine. Easy to install and use.

There are many factors that affect the quality of pellets, which are made by poultry feed pellet making machine. It is generally believed that feed formulation has the greatest impact on pellet quality, and steam conditioning can play a greater role on the basis of formulation.

In industrial production, most poultry feed mills use the wrong steam method. Try to use high-pressure high-temperature steam to increase the adjustment temperature and increase the water absorption capacity. But this idea was wrong from the start!

Over-temperature steam mainly provides sensible heat, but cannot meet latent heat and humidity requirements. The elevated temperature steam is fed into the regulator with superheated steam.

Superheated steam has high sensible heat, can quickly reach the temperature signal sensor, and reach the set temperature of 85 ℃ – the sensor sends a signal to adjust the automatic flow control valve into the steam flow. Therefore, the steam flow into the conditioner is not large. Water vapor is reduced, latent heat is reduced, and water content is reduced. (Related case: pellet production line in Thailand)

It should be noted that steam granulation is mainly water, and heat is closely related to temperature. You cannot only focus on one and ignore the other. In fact, people often ignore the important factor of moisture, and blindly emphasize the tempering temperature.

Question 2: Too short a conditioning stay is a common problem.

Many people don’t notice the conditioning time of soda water, some conditioning time is only 3-5 seconds, which has a very adverse effect on achieving the ideal steam-material relationship. It should be emphasized that, before the cooked raw starch is transferred from the poultry feed pellet making machine conditioner to the conditioner, it must be highly valued that the cooked raw starch reaches the set temperature.

The total retention time of the preconditioner and the time inside the conditioner boils down to “total conditioning time”, which is inconceivable because it ignores all the logic of food science.

Question 3: The problem caused by insufficient conditioning is the reason for the decrease in moisture absorption after steam conditioning.

In the production process of pellet feed, steam conditioning is not ideal. Adding feed to poultry pellet feed improves the economic benefits of broiler production by improving feed efficiency of poultry feed pellet making machine. (Related case: feed mill plant in Uzbekistan)

This is mainly attributable to reducing feed waste, increasing volume, increasing nutrient concentration, indiscriminate feeding, reducing time and energy for feeding, reducing component segregation, destruction of feed pathogens, thermal denaturation of starch and protein, and improving palatability.

However, if proper temperature conditioning is not employed, particulates can cause poor production performance.

The results show that granulation can cause changes in starch properties, and it is not easy to be hydrolyzed by enzymes. Previously adding broilers to a conditioned basal diet at 93°C resulted in significantly reduced weight gain and increased feed consumption compared to 85°C.

Due to the loss of lysine and arginine due to maillard reaction, starch ages into anti-enzymatic starch, resulting in energy loss. Drain, these are known negative effects of high temperature conditioning.

Starch can also lead to reduced starch digestibility if not heated properly. Amylose can recrystallize after heating, and its digestibility is lower than before heating. Overheated starch can cause caramelization reactions, mainly the condensation of amino acids and sugars into indigestible maillard products.

Increasing the poultry feed pellet making machine conditioning temperature could increase the yield of the wheat basal diet, but had no significant effect on the corn basal diet. This finding may be due to differences in the gelatinization properties of wheat starch at lower gelatinization temperatures compared to corn.

Compared with corn starch, wheat flour can provide a higher gelatinization temperature than corn starch after conditioning at 90 °C, thereby increasing the PDI of wheat-based daily feed. However, it should be noted that during the poultry feed pellet making machine conditioning process, due to the low water content, the degree of gelatinization during granulation is generally low.

Except for the gelatinized starch, the components are mainly used to improve the physical quality of the granules. The results showed that with the increase of poultry feed pellet making machine conditioning temperature, the PDI of the wheat basal diet was improved, but there was indeed a negative effect on weight gain and feed absorption and utilization.

Therefore, although it is generally believed that the durability of poultry feed pellet making machine pellets is related to better production performance, the high durability of pellets obviously cannot overcome the adverse effects of high temperature conditioning on production performance.

Because of the mechanical shear force, high temperature, conditioning time, moisture and other factors in the feed processing process, it can cause the denaturation of feed protein, but the solubility is reduced and the digestibility utilization rate is increased.

In general, heating increases protein digestibility by inactivating enzyme inhibitors, and heating denatures proteins, allowing more enzyme access to sites. Improper vapor conditioning can greatly affect digestible protein content.
