Feed Ingredients Mixing, Water Adding Fuel Injection
Mixing raw materials can improve uniform distribution of different feed particle sizes, resulting in feed pellets with almost identical hardness. The use of water to add water to the mixer is still being explored. The addition of 1% to 2% water to the mixer in hard pellet production is beneficial for improving the stability and hardness. However, increased water can have a negative impact on cooling and drying pellets as well as the pellet storage. You can add 20-30% water to the powder, and 10 percent water to the mixture for wet pellet feed production. This is much easier than adding water during conditioning. High-moisture materials make feed pellets that are low in hardness, soft and easy to digest. This can help improve the performance of poultry and livestock production. Wet pellet feed is suitable for large-scale farms. Wet pellets cannot be stored so they should be used immediately after being produced. To meet animal nutrition requirements, fats are generally added to the mixture. While adding 1% to 2% fats won't significantly decrease the pellet hardness, 3% to 4% fats will reduce its impact on the granules. You should control how much fat you add. pig feed ingredients
The key to feed pellet production is steam conditioning. The conditioning effect directly impacts the granule's internal structure and quality. Two important factors that influence conditioning effect are steam quality and the conditioning period. Saturated steam and high-quality steam can produce more heat to raise the temperature of materials. This makes starch gelatinized. The higher the starch gelatinization rate, the longer the conditioning period. These granules have a compact structure, high stability, and great hardness. You can adjust steam addition to maintain a temperature of 70-80 degrees Celsius for poultry and animals. You can adjust the length of conditioner, paddle angle, and rotation speed to keep conditioning time at around 30 seconds. To improve temperature and extend conditioning period for fish feed, a double-layer or multilayer jacketed conditioner can be used. This helps to strengthen fish feed pellet stability and hardness.
Ring die
Granule hardness can be affected by the compression ratios and aperture of a ring die. If you use ring dies that have the same aperture, but with different compression ratios, the pellet hardness will increase. You can make pellets that are right-hardened by using the correct compression ratios.
Pellet length also plays a significant role in the pellet's pressure bearing capacity. The hardness of pellets with the same diameter and without defects is greater if they are longer. Adjusting the position of cutting blades can help ensure that the granules are equal in length and hardness. The granule's hardness is also affected by the size of its diameter section. The 8-shaped section is more resilient to pressure and can be tested at a higher hardness than the circular section. The material of the ring dies can also influence granule appearances and hardness. The pellets produced by ordinary steel rings die are significantly different from those made by stainless steel rings die.
Post-curing and post-spraying
Post curing and spraying are not used in poultry and livestock feed production, but they are widely used in fish and aquatic feed production. The pellets can be fully gelatinized by post curing. Starch gelatinization is a way to strengthen the pellet's internal structure and prevent water infiltration. This improves aqua pellet hardness, stability, and hardness. Hot pellet feed spraying technology uses post spraying. The pellet's interior will be softer due to fats and other chemicals that were sprayed.
Cooling and Drying Pellets
To prolong the storage time and ensure good quality pellets, dry and cool feed pellets are essential. We test the pellet hardness by cooling the same pellets several times over different cooling periods. The cooling time has no effect on the pellet's hardness for pellets with lower hardness. However, for pellets with greater hardness, the cooling duration has a significant impact on the pellet's hardness. It is likely that pellet brittleness increases due to internal moisture loss. This causes the pellets to be less hard. We find that pellets with a lower hardness and more surface cracks are produced when they cool in a slower manner. It is also worth noting that crushing large pellets into smaller particles can dramatically reduce their hardness.
Factors that influence pellet hardness in feed pellet manufacturing are many. People can learn more ways to regulate granule hardness. We will soon be able to produce pellet feed that is preferred by animals.
Poultry feed making machine is the bigger poultry feed production equipment with output 1200-1500kg/h, and it is very good to medium poultry farm.
