Poultry feed refers to the feed of animals such as chickens, ducks, geese, quail, turkeys, pigeons, and birds, etc. In modern poultry production, from brooding, rearing to later stages, in the production of poultry such as laying hens, broilers, ducks, and geese, in order to better develop the production potential of poultry, it is necessary to feed them with compound feed made by poultry feed pellet machine with reasonable ratio and complete nutrition according to their nutritional needs. In poultry production, feed consumption accounts for 70-80% of production costs.
Poultry pellet feed is a strip feed made by squeezing powder feed with a poultry feed pellet machine. It is a popular form of feed nowadays. In recent years, with the rapid development of the feed industry, poultry pellet feed has gradually been accepted by the majority of poultry farmers, and the amount has continued to increase. Therefore, for poultry feed processing plants or poultry farms, the establishment of feed factories, feed production lines or the purchase of poultry feed pellet mills are all very promising investments.

After a large number of poultry feeding experiments, the survey data proves that the feeding effect of pellet feed has obvious economic benefits. The specific advantages of poultry pellet feed are as follows:
Increase poultry animal feed intake and reduce feeding waste.
When the poultry feed formula is changed, it can be more acceptable to animals.
Improve the conversion rate of feed digestion.
Prevent picky eaters from poultry animals to ensure a good nutritional formula.
After high temperature and steam sterilization, such as eliminating Salmonella in poultry feed.
High-quality poultry feed pellets can withstand repeated handling and remain intact during bagging, transportation, storage and delivery in the feeding line.

5.Different types of poultry feed machine conditioners can be selected according to needs, such as single-layer conditioner, double-layer conditioner, three-layer conditioner and dual-axis differential conditioner, etc.
The working principle of the ring die poultry feed pellet machine is: the mixed powder with a moisture content of not more than 15% enters the feeding screw conveyor from the bin to be granulated, and the appropriate material flow is obtained by adjusting the speed of the feeding screw conveyor shaft, and then enters the conditioning device for conditioning with steam, and enters the ring die cover through the bypass chute of the iron removal device, and the powder is rolled into the pressing zone by the feeding scraper.
The drive shaft drives the ring die to rotate, and the powder is rolled. Between the ring die and the pressure roller, the two relative rotating parts gradually squeeze the powder material into the ring die hole to form, and continuously extrude the pellets to the required length and flow out of the poultry feed pellet machine. The structure overload protection of the poultry feed pellet processing machine and the electrical control system feeder ensure that the materials from the silo can evenly enter the pellet machine for poultry feed, and the screw conveyor is often used as the feeder to feed the poultry pellet making machine evenly.
What's poultry animal feed pellet machine price? Because different customers have different requirements for pellets, there will be many differences in the details of our feed pellet machine design. Therefore, the actual poultry feed pellet machine price for different projects are different. Even if the customer wants to produce the same type of pellets, if the customer's feed formula, raw materials, and production technology are different, the poultry feed pelletizer machine ring die, conditioner, etc. will be different.

How to control the quality of poultry feed pellet machine pelleting process?
Requirements for poultry feed making machine before granulation
It is required to inspect and maintain the poultry feed making machine before production to ensure the quality of the product. It includes the following aspects:
The pellets and the magnets on the top should be cleaned once every shift. If they cannot be cleaned, the iron in the feed may enter the poultry feed pellet mill ring die and affect the normal operation of the poultry feed pelleting machine.
Monitor the wear of the ring die and press roller: the wear of the press roller may affect production capacity; excessive wear of the press die reduces the effective thickness of the press die and affects the quality of the pellets.
Add lubricating oil to the pressure roller regularly to ensure the normal operation of the pressure roller.
Check whether there is material backlog in the cooler, and check whether the cooling plate or screen surface in the pellet cooler is damaged.
The roller of the poultry pellet crumbler should be inspected regularly: if the corrugated teeth of the roller wear and become blunt, it will reduce the crushing capacity and reduce the quality of the product.
Check every shift whether there are holes, blockages and adhesion on the screen surface of the grading screen, and the screen surface is intact and undamaged to achieve the correct particle classification effect.
Check the cutter of the poultry feed pellet making machine: the cutter is worn too blunt, which will increase the powder of poultry feed.
Check the steam separator of steam to ensure the quality of steam entering the poultry feed pellet machine conditioner. Otherwise, it will affect the annual production capacity of the light beam and the pellet quality of the poultry feed.
When replacing raw materials, check whether the buffer bin and finished product bin above the granulator are completely emptied to prevent mixing.
Poultry feed generally contains corn with high starch content and low crude fiber content. Therefore, the structure and strength of poultry pellet feed rely on tempering technology, using heat and steam to soften the raw materials to improve the pelleting performance of the feed. During the poultry feed pellet production machine conditioning process, the starch of the feed will be partially gelatinized, and the gelatinized starch has the effect of binding, which improves the pellet forming rate of the poultry feed.
Generally, the conditioning time of the poultry feed making machine conditioner is 10~20 seconds. Extending the conditioning time can:
Increase starch gelatinization;
Increase feed temperature and reduce harmful microorganisms;
Improve poultry feed production efficiency and particle quality. When the steam pressure is low, heat and water can be dissipated faster. In order to improve the quenching and tempering effect, the steam pressure must be controlled. Generally, poultry pellet feed can be adjusted to 16~18% moisture and 75~85°C according to actual operation requirements.
The correct adjustment of the pressure roller gap can prolong the service life of the poultry feed pellet machine ring die and the pressure roller, and improve the production efficiency and poultry pellet quality. The adjustment requirements are as follows:
Adjust the poultry feed pelletizer machine pressure roller so that when the ring die rotates at a low speed, the pressure roller can only touch the high point of the poultry feed machine ring die. This gap minimizes the metal contact between the pellet machine ring die and the pressure roller, reduces wear, and there is enough pressure to rotate the pressure roller.
Grinding particle size of poultry feed making raw materials
The particle size requirements for raw material crushing should be determined according to the particle size of the poultry feed pellets made by poultry feed pellet maker. The particle size requirement is too fine, the processing speed is low, and the productivity is low; the particle size is too coarse, the pellet forming rate decreases, and the pellets are easy to break. Poultry feed particle size is different, so when selecting feed, it is necessary to select the feed according to the growth of the poultry, and the particle size of the feed can also be adjusted according to the different purposes. Taking chicken feed as an example, the weight gain of chickens eating small particle size feed is significantly higher than eating large particle size feed. The crushing particle size of grains in broiler feed is preferably 700～900μm. Laying hens are not sensitive to the pulverization degree of feed, and it is generally appropriate to control it at 1000 µm.
In poultry feed processing, chicken and duck feed requires coarser particle size, and generally requires that the pellet feed has a large hardness and a low powdering rate to reduce feed waste. To increase the hardness of the pellet feed for poultry, the purpose of increasing the hardness of the pellet can be achieved by adjusting the coarse, medium, and fine ratio of the raw material crushing particle size. Coarse particles mean that the particle size is above 900μm, which requires no more than 15%, medium particles mean that the particle size is about 700μm, which is about 35%, and fine particles mean that the particle size is below 500μm, which requires more than 50%.
Among them, the fine powder with a particle size of less than 250μm is not less than 25%. The starch in this part of the fine powder can be fully gelatinized during conditioning, and plays an important role in the poultry feed pellet machine granulation process. It binds coarse, medium and fine particles together into large pellets feed for poultry, which not only improves the hardness of the pellets, can also reduce the powdering rate of the product.
Pellet forming rate:Used for sieving granular feed with a sieve of less than 20% of the pellet size. If the poultry pellet feed has a pellet size of 5.00mm, use a 4.00mm sieve. The percentage of the sieve can represent the forming rate of the pellets. The pellet forming rate of poultry and livestock feed is required to be greater than 95%, and the pellet forming rate of fish and shrimp feed is required to be greater than 98%.
Pellet length: The length of poultry feed pellets with a diameter of less than 4mm is 2 to 5 times the pellet size, and the length of poultry feed pellets with a diameter of 4 mm or more is 1.5 to 3 times the size.
Poultry needs to consume various nutrients in growth, reproduction, production, and maintenance of basic needs. The needs for these nutrients are the main and the second, and the requirements are also different. But in general there are several categories: energy, protein and amino acids, fats, minerals (including trace elements) and vitamins, and water.
Energy
Organic substances in feed-carbohydrates (starch, sugar, fiber), protein, and fat all contain energy. Energy is necessary for all physiological processes of poultry (such as exercise, breathing, circulation, absorption, excretion, reproduction, production, etc.) . Energy occupies a certain proportion in animal feed and keeps other nutrients and available energy in balance. This is the most important principle in modern nutrition, that is, energy is the carrier of various other nutrients.
Protein and amino acids
Protein is the basis of life, a component of cell protoplasm, and a basic component of various enzymes, hormones and antibodies. It is also the most important ingredient in poultry products such as meat, eggs, feathers, and offal. Protein cannot be replaced by other substances (such as carbohydrates, fats). When the protein and amino acids in the feed are insufficient, the performance of poultry will be greatly affected. There are 10 essential amino acids for poultry: lysine, methionine, isoleucine, arginine, tryptophan, threonine, histidine, phenylalanine, valine, leucine.
Fat
Fat is also a component of cell protoplasts, but when poultry forms body tissues and repairs old tissues, carbohydrates can be converted into fat in the body, and most of them do not need to be supplied from feed. Some fatty acids cannot be synthesized in the animal body by themselves and must be supplied from the feed, such as linoleic acid and linoleic acid, which are called essential fatty acids. Linoleic acid can be converted from linoleic acid. Generally 0.8 to 1% of linoleic acid in feed is sufficient.
Minerals
Minerals are the most important components of poultry body tissues and cells, especially bones. It is involved in regulating osmotic pressure and maintaining acid-base balance in the body.
Mineral elements can be divided into macro mineral elements and trace mineral elements according to the amount added in the feed. There are major mineral elements: calcium, phosphorus, magnesium, sodium, potassium, sulfur, and chlorine; trace mineral elements: iron, copper, cobalt, manganese, zinc, iodine, selenium, etc.
Vitamins
The main function of vitamins is to control and regulate metabolism in the body. Because poultry is not like livestock, it lacks some microorganisms in its digestive tract, most vitamins cannot be synthesized in the body and must be supplied from feed. Vitamin deficiency can cause metabolic disorders, often leading to a series of syndromes, which seriously affect the growth and production of poultry, especially breeding poultry and chicks, which have stricter requirements for vitamins.
At present, it is known that there are 13 kinds of vitamins that poultry must take in the feed, of which 4 kinds of fat-soluble vitamins: A, D, E, K; 9 kinds of water-soluble vitamins: vitamin C, vitamin B1 (thiamine), vitamin B2 ( Riboflavin), vitamin B3 (pantothenic acid), vitamin BPP (niacin), vitamin B6 (pyridoxine, pyridoxine hydrochloride commonly used in production), biotin, choline (choline chloride commonly used in production), folic acid , vitamin B12.
Water
Water is the most important ingredient in life besides air. It is the basic substance of blood, intercellular fluid and intracellular fluid. The water content of 1-week-old chicks is about 85%, and that of 42-week-old chicks is 55%. The water content in the egg is about 70%. In animals, the digestion and absorption of nutrients, the transportation of metabolites, and body temperature regulation all play an important role. In production, we generally require that poultry (especially intensively raised) have clean drinking water for 24 hours. Especially in summer, it is very important.
