1.The common raw materials of 8t/h automatic complete poultry feed pellet line are mainly consist of corn, wheat, barely, oats, sorghum, soyabean, soyabean meal, fish meal, amino acids, miscellaneous meal, whey powder, oil, meat and bone meal, grains, feed additives etc. more than ten varieties of raw materials.
2.Introduction of Main Process of Poultry Chicken Complete Feed Pellet Line 8-11 Tons per hour:
The features of this 8-11tph poultry chicken feed mill processing plant are that the crush fineness is moderate (the hole diameter of screen is 2-4mm), the curing degree is moderate (the pellet mill use double-layer conditioner), the diameter size of finish pellets is large (about 2.5-4mm). This feed mill plant's capacity is designed to be 10tph, using one grinding process, one automatic dosing process, one mixing process, one pelleting process and one bagging process. The total power of this line is about 390kw, the working land size is about 16*11*26m, and matching 1ton boiler. The 8t/h automatic chicken poultry feed line for pellet has compact design, reasonable structure and meets the requirement of environmental protection. It can be customized according to customer's requirements.

4. The size of chicken feed pellets (taking laying hens as an example)
The size of feed pellets in poultry production is often overlooked. During the chicken feed line production process, feed manufacturers often cannot ensure that the feed pellets are uniform in size, and that the feed ratio is completely mixed and even. The pellet size of the diet is uneven, some are very fine, some are very rough, different grinding and crushing methods will also cause different distribution of chicken feed pellets, even if the overall nutrition of the feed is similar, different pellet sizes will affect the digestion and absorption of the feed and production performance of poultry. Therefore, chicken poultry feed mills should constantly evaluate the size and distribution of feed pellets to minimize the impact factors.
(1) Effect of poultry chicken feed pellet size on digestive system
The development of the digestive system is affected by the size of the feed particles. Poultry eating larger particles of feed can promote the development of the stomach and increase the length of the intestine. The feed with larger particles stays in the muscular stomach for a longer time, and the feed is ground into small particles before being released into the small intestine. The longer the intestinal villi, the greater the surface area for digestion and absorption, which in turn increases the digestion and absorption of nutrients. Researchers believe that feeding large pellets can promote the secretion of digestive enzymes in the small intestine, which is beneficial to the digestion and absorption of nutrients.
When feeding fine-grained feed (powder), the feed does not need to be milled and quickly enters the glandular stomach through the muscular stomach, causing the muscular stomach to become smaller and the glandular stomach to expand, reducing the length of the intestine. Therefore, it is not recommended to use too fine feed.
(2) Ideal feed pellet size
The size of feed pellets will seriously affect the feed intake of poultry. The ideal feed particles should increase with the development of the chicken's beak, muscle stomach, and digestive organs. Laying hens tend to eat large pellets, and this preference is more pronounced with increasing age.
In the first 6 weeks, 1-3mm powder is generally used as the starting food. For chicks, the nutrients in the powder are more uniform, but as the age increases, continuous feeding of the powder will lead to changes in the chicken's stomach and intestine. small.
After opening the food, change to a uniform powder to ensure the development of digestive organs. 55–85% of the feed particles in the powder are 1-3 mm in size and the geometric mean diameter is 1200 μm. The prenatal feed should contain 2-4 mm diameter stone powder feed, which is conducive to ensuring the quality of eggshells.
a. Feed pellet size (grain)
The feed pellet classifier classifies feed samples according to pellet size.
• It can be used in chicken farms to detect the pellet size of feeds sent from feed farms-when the feed is delivered or sampled from the feed tower.
• Evaluate the uniformity of feed particle size for the entire feeding system—sampling from multiple points.
b. Too much fine-grained feed
• Reduce feed intake and nutrient absorption
• Increase the dust in the house
c. Too much coarse-grained feed
• Chickens will choose large pellet feed
• Increase the risk of feed separation
d. The best pellets
• An interval of 3–4 hours at noon allows the flock to consume fine-grained feed. Daily consumption of fine feed pellets is an important balance of nutritional intake.
• Add at least 0.5% fat or liquid fat to the feed to help mix and adhere small pellet feed.
• Use large pellet feed or broken feed to increase feed intake when the climate is hot.
