Working Principle Of Pig Feed Pellet Machine

The working principle of the pig feed pelletizer machine: The powdered material is a discontinuous combination composed of dispersed particles with fluidity. The prerequisite for being compressed into particles is that there is a gap between them.

Therefore, under the action of squeezing, the gap between the powder particles is reduced, the particles move closer to each other and rearrange, the bonding force increases, and finally it is pressed into a pellet feed with a certain density and a certain strength.

In this process, due to the action of steam, the starch in the feed is gelatinized, and the protein and sugar are heated to produce plasticity, so granulation is an extrusion-type thermoplastic process.

faqs Of pig Feed Pellet Machine

What are the advantages of Pig Feed Pellet Machine?

After the various raw materials of the pig feed are grinded and mixed, they can be used as powder for feeding or for further processing, and heating or pressure is usually required during processing. Making them into pellets is the most common method. The RICHI pig feed pellet making machine can be used to process pig feeds of different breeds and growth cycles, such as piglet feed, fattening pig feed, and sow feed.

Why feed pigs with pellets feed instead of powder feed?


High stability

Powdered feed is prone to damp, clumping, and even mildew; powdered feed is easily oxidized when exposed to the air for a long time, but the pellet feed has little contact with the air after being squeezed, and the storage time is relatively long. In addition, the pellet feed has been processed during the processing process, and the moisture-proof effect is good.


Good palatability

Pellet feed contains some condiments such as honey and oil during processing, and the diet of pigs will also increase; pigs like to eat plant rhizomes, and pellets are made of imitating plant rhizomes, which have relatively good palatability. In addition, Pellet feed is matured and extruded, which changes the feed structure, and the appetite of pigs will increase.


High feed conversion rate

Pigs' sense of smell is more sensitive than dogs' sense of smell. This feature can help them find food, even a few meters underground. So pigs always pick and choose when they eat feed. Some feed will be spilled, compared to powder feed, pellets feed will not cause excessive waste of feed, and can ensure the conversion of nutrients.


Reduce stratification

Pig farmers may find such a problem when using self-mixing ingredients. Some formulated feeds have stratification. Because the density and volume of various powders are different, there will be stratification when put together. This situation will lead to uneven nutrient distribution, which is not conducive to the growth of pigs.

In addition, the powdered feed is dusty, which is easy to infect pigs with respiratory diseases, and the pellets will not have such problems, thereby ensuring the health of the pigs.


Feed pellets are safer

Self-prepared feed is easy to be infected by bacteria, viruses, etc., because the raw materials may be contaminated during the process from harvesting to transportation to storage and preparation. Bring losses to the pig farm. The pig feed pellets are pellets made with steam and high temperature. During the pig feed pellet machine production process, the high temperature can effectively kill pathogens, which leads to the safety of the feed.


Feed pellets are easy to transport

The volume of powdered feed becomes smaller after compression, and it is better to transport than powdered feed, which can effectively save transportation and storage space.

What are the Precautions before pelleting pig feed by pig feed pelleting mahcine?

  • Choose as many raw materials as possible. Many kinds of pig feed raw materials can play a complementary role in nutrients, but attention should be paid to the efficiency of the use of nutrients in the raw materials by pigs.
  • The quality of feed ingredients must meet the standards. The raw materials can be purchased in accordance with the relevant standards of different countries, and the low-quality raw materials must not be purchased for cheap.
  • Use local cheap feed ingredients as much as possible. The feed material resources vary from place to place. Some cheap feed materials such as rice bran and bean curd residue can be used to reduce breeding costs.
  • The supply of feed ingredients should be adequate. For some raw materials that are sometimes not available, it is best to avoid using them, because frequent replacement of raw materials can cause stress to pigs.
  • Pay attention to the palatability of feed ingredients. Although some raw materials are cheap, their palatability is not good, so pay attention to limit the amount of these raw materials. Conversely, for those ingredients that have very good palatability, consider limiting the amount of feed to prevent digestion problems due to overeating.
  • Design the pig feed formula strictly in accordance with the breeding standards, and avoid arbitrariness. The breeding standards are based on the results of breeding experiments. Some standards include the NRC standard in the United States, the ARC standard in the United Kingdom, and the national standard in China.
  • Mix and stir evenly. Some raw materials with small addition amount need to be pre-mixed first, and then added to the aniseed material for mixing.

How to control the hardness of pig feed pellets made by pig feed pellet machine?

The pellet hardness of pig pellet feed is an important indicator of the appearance quality of pellet feed. In the feeding process of some pig farms, it was also found that the hardness of pellet feed has a certain impact on the performance of livestock and poultry.

Throughout the whole process of pig pellet feed production technology, in addition to the pig feed formula, the pig feed processing technology that affects the pellet hardness of pellet feed includes: raw material crushing process; raw material expansion process; raw material mixing, water addition and oil injection process; steam pretreatment quenching and tempering process; selection of dies in the pig feed pellet machine granulation process; post-curing and post-spraying process; drying and cooling process.


The impact of crushing process on pig feed pellet hardness

The decisive factor in the crushing process for the hardness of the pellets is the crushing particle size of the pig feed raw materials. Generally speaking, the finer the raw material is crushed, the easier the starch is to gelatinize during the pig feed pellet machine conditioning process, the stronger the binding effect in the granules, the less likely the granules are to break, and the greater the hardness.

In actual production, according to different The production performance of animals and the size of the aperture of the ring die, the crushing particle size shall be adjusted appropriately, the suckling pig feed shall be finer, the crushed average particle size shall be 400-500μm, and the average particle size of the fattening pig feed shall be 600-700μm.

In the production of pig feed, the hardness of the pellets is generally required to be moderate. Too hard will reduce the palatability and production performance of the product, and too brittle will increase the powdering rate of the product, reduce production performance, and increase waste.

In the production of pig feed, it is generally required to crush more than 70% of the particle size between 700 and 500 μm, and more than 20% of the fine powder below 250 μm. Such a particle size distribution is conducive to the granulation and shaping of the pellets and the improvement of the appearance quality of the pellets, and can ensure the proper hardness of the product and a lower powdering rate.


The impact of raw material expansion process on pellet hardness

Through the puffing and swelling treatment of the raw materials, it can destroy the anti-nutritional factors in the raw materials, remove the toxins in the raw materials, kill bacteria, eliminate harmful substances, denature the protein in the raw materials, and fully gelatinize the starch. The gelatinized starch has a significant effect on the hardness of the pig feed pellets.

At present, the extruded raw materials are mainly used in the production of high-grade suckling pig feed and special aquatic feed. For suckling pig feed, the pellets are required to be crisp and not too hard, which is conducive to the feeding of suckling pigs. However, the puffed suckling pig pellets have a larger gelatinization degree of starch, so the hardness of the granulated pellets made by pig feed pellet machine is also larger, and the hardness of the pig feed pellets should be reduced by other means.


The influence of raw material mixing, water addition and oil injection process on the hardness of pellets

The mixing of raw materials can improve the uniformity of various pellet size components, which is beneficial to keep the hardness of the pellets basically the same and improve the product quality. The process of adding water in the pig feed mixer is still a problem that is being actively explored. In the production of hard pellets, adding 1% to 2% of water in the animal feed mixer is beneficial to improve the stability and hardness of the pellets.

However, due to the increase of moisture, it has a negative effect on the drying and cooling of the pellets. It is also unfavorable for product storage. In the production of wet pellet feed, up to 20%-30% of the water can be added to the powder, and it is easier to add about 10% of the water in the mixing process than in the conditioning process.

The formed pellets of high-moisture materials have low hardness, softness, and good palatability, which can improve the production performance of pigs. This kind of wet pellet feed made by pig feed pellet forming machine can be used in large-scale breeding enterprises. Wet pellets generally cannot be stored, and are generally required to be produced and fed.

Adding grease in the mixing process is currently a grease addition process commonly used in feed production workshops. The addition of 1% to 2% of grease does not significantly reduce the hardness of the pellets, and the addition of 3% to 4% of grease can significantly reduce the hardness of the pellets.


Influence Of Steam Conditioning Process On Pellet Hardness

Steam conditioning is a key process in the processing of pellet feed by pig feed pellet machine. The quality of the pig feed pellet mill conditioning directly affects the internal structure and appearance of pellets. Steam quality and conditioning time are two important factors that affect the conditioning effect. High-quality dry saturated steam can provide more heat to increase the temperature of the material and gelatinize the starch.

The longer the conditioning time, the higher the starch gelatinization degree, the denser the formed particle structure, the better the stability, and the better the hardness. Bigger.

For general pig feed, by adjusting the amount of steam added, the tempering temperature is maintained at 70-80°C, and the tempering time is controlled at about 30 seconds by changing the length of the pig feed making machine conditioner, blade angle and rotation speed. For high-end pig feed, double-layer or multi-layer jacket conditioner are generally adopted to increase the conditioning temperature and extend the conditioning time.


The influence of the pig feed pellet machine ring die on the pellets hardness

The technical parameters such as the aperture and compression ratio of the pig feed pellet mill ring die can significantly affect the hardness of the pellets. The hardness of the pellets formed by the ring die with the same aperture but different compression ratios increases significantly with the increase of the compression ratio.

Choosing a suitable compression ratio ring die can produce pellets with suitable hardness. The length of the pellets has a significant impact on the pressure-bearing capacity of the pellets.

For pellets of the same diameter, if the particles have no defects, the longer the pellet length, the greater the measured hardness. Adjusting the position of the pig animal feed pellet machine cutter to maintain a proper pellet length can keep the hardness of the pellets basically the same. The cross-sectional shape of the pellet diameter also has a certain effect on the hardness of the pellets.

The 8-shaped cross section has a stronger pressure bearing capacity than the circular cross section, and the measured hardness value is also greater. In addition, the material of the pig animal feed pellet making machine ring die also has a certain influence on the appearance quality and hardness of the pellets. There is a significant difference between the pellets produced by ordinary steel ring dies and stainless steel ring dies.


The influence of drying and cooling process on pellet hardness

In order to extend the storage time of pig feed products and ensure product quality within a certain period of time, the pig feed pellets need to be dried and cooled as necessary.

In the test to determine the hardness of the pellets, the hardness of the pellets was measured after cooling the same product for 5 minutes, 10 minutes, and 15 minutes several times. It was found that the hardness of the pellets with low hardness was not significantly affected by the cooling time, but the hardness was higher.

Larger pellets decrease in hardness as the cooling time increases. This may be because as the water inside the particles is lost, the brittleness of the pellets increases, which affects the hardness of the pellets. At the same time, the particles are rapidly cooled by large air volume (cooling time is 3 minutes) and small air volume (the air door is closed to one third) and slowly cooled (cooling time is 20 minutes).

It is found that the hardness of the former is lower than that of the latter. The surface cracks of the pellets have increased. In addition, it is worth mentioning that crushing large hard pellets, turning large pellets into small crumbled pellets, can significantly reduce the hardness of the pellets.

What are the main ingredients and formulas of pig feed??

  1. Bran raw materials: mainly include rice bran, wheat bran, sweet potato vine bran, peanut vine bran, broad bean leaf bran, soybean straw bran, etc. The dosage is 10%-15% of the total amount of feed, and the maximum is no more than 20%.
  2. Cake and meal raw materials: mainly include rapeseed cake, peanut cake, cottonseed cake, soybean cake, sesame cake, etc. The mixing ratio is generally 10%-25% of the total amount of feed. Soybean cake and peanut cake are nutritious and can be mixed with 20%-25%; rapeseed cake and cottonseed cake can be mixed with 8%-10%.
  3. Residue raw materials: mainly include distiller's lees, bran lees, vinegar lees, powdered dregs, bean dregs, sugarcane bagasse, etc. The general dosage is 5%-10% of the total amount of feed. Pregnant sows and later fattening stages should not be fed distiller's grains.
  4. Grain raw materials: mainly including corn, barley, wheat, sorghum, broad beans, peas, etc. The general dosage is 50% of the total amount of feed, with a maximum of no more than 60%.
  5. Animal raw materials: including silkworm pupae, fish meal, bone meal, blood meal, feather meal, etc. The general dosage is 4%-8% of the total amount of feed. Piglets should not be fed blood meal. Fish meal can be mixed with 5%-8% in fattening pig feed. When using this type of feed, attention should be paid to the content and proportion of calcium and phosphorus.
  6. Mineral raw materials: mainly include shell powder, eggshell powder, calcium carbonate, calcium phosphate and salt. The general dosage is 1%-2% of the total amount of feed. The dosage of salt should not exceed 0.5%. If trace elements are added, they must be used in strict accordance with the prescribed amount.
  7. Green raw materials: mainly include aquatic duckweed, water lily, water hyacinth, water peanut, leaves and vines of crops, and cultivated ryegrass, alfalfa, wild rice, etc. This type of feed is green, juicy, nutritious, and easy to digest. It generally accounts for 35%-40% of the total feed.
