Small Feed Pellet Machine

The structure of a small feed pellet machine:

It is composed of a motor (diesel engine), a gearbox, a main shaft, a coupling, a die plate, a pressure roller, a feed hopper, a cutter, and a discharge hopper.

Working principle of small feed pellet mill:

The small flat die pellet machine is based on mechanical circular motion. A diesel engine and electric motor drive the drive shaft, and transfer gears to the main shaft and template, so that the template rubs the pressure wheel and rotates. Under the pressurized pressure wheel, the material moves from the template Extrude from the hole, cut by the cutter, and finally roll out the pellets from the discharge port. The large and medium-sized flat die pellet machine is driven by the motor to drive the belt pulley to the gearbox or the motor directly connects the gear in the gearbox to the gearbox as the power, which is transmitted to the pressure roller assembly on the main shaft of the gearbox. , Under the pressure of the pressing wheel, the material is extruded from the template hole, cut by the cutter, and finally rolled out of the material opening.

The working process requires a mixed powder with a moisture content of not more than 15%, enter the feed auger from the hopper, adjust the speed of the step-less speed regulation motor to obtain a suitable material flow, and then enter the agitator, stir, and steam through the stirring rod Mixing and conditioning. If you need to add molasses or fat, add it from the mixing drum to condition with steam. The amount of fat added is generally not more than 3%, otherwise it will be difficult to form. After conditioning, the temperature of the mixed powder can reach 64～85℃, The humidity reaches 14～l 6%. Then the chute through the optional iron absorption device to remove the iron impurities mixed in the powder, and finally enter the pressing chamber for granulation.

Raw material for pellet feed:

The raw materials of the pellet feed for cattle, sheep, and rabbits have a wide range of sources, such as corn stover, bean straw, wheat straw, rice straw, flower seedlings (husks), sweet potato seedlings, alfalfa grass, rape straw and so on. After the forage grass is made into pellets, it has high density and large capacity, which is conducive to long-distance transportation. It realizes the digestion and utilization of crop stalks in different places, increases the value of the stalks, increases the income of farmers, and protects the ecological environment in the development of agriculture and animal husbandry. Pellet feed has good palatability after high-temperature maturation and gelatinization and is loved by farmers. People vividly call it the "biscuits" for cattle and sheep. The raw materials of pig, chicken, fish, pigeon, duck, and goose feed are all refined materials, such as corn, soybean meal, cotton meal, etc., with high bonding rates, which can soften and mature the materials in advance, so as to better pelletize and increase The gloss of the particles.

Technical data of Samll feed pellet mill:

Features of flat die feed machine:

1. Automatic feeding: time-saving and labor-saving, convenient operation, and high production efficiency.

2. Stable working performance: strong crushing fineness, safe and reliable.

3. Durable: The steel structure components are solid and reliable, and the high-power self-aligning bearings are used for long life.

4. Low cost of use: low power; good tool material, double-sided edge, can be re-grinded many times.

Advantages of pellet feed:

1. Avoid picky eating by animals. The compound feed formula has a variety of raw materials with comprehensive nutrition, which can prevent animals from picking their favorite food from the powder and refusing to take in other ingredients. Since pellet feed can maintain uniformity during storage, transportation, and feeding, feeding loss can be reduced by 8% to 10%.

2. High feed rate of return. During the pelleting process, due to the comprehensive effects of moisture, temperature, and pressure, the feed will undergo some physical and chemical reactions, which will gelatinize the starch and increase the activity of enzymes, which enables the fed animals to digest the feed more effectively, which translates into weight gain. Feeding poultry and pigs with pellet feed can increase the feed conversion rate (that is, the rate of return) by 10%-12% compared with powdered feed. Feeding fattening pigs with pellet feed has an average daily gain of 4%, and the feed-to-meat ratio is reduced by 6%; feeding broilers, the feed-to-meat ratio can be reduced by 3%-10%.

3. Storage and transportation are more economical. After pelleting, the bulk density of the feed will generally increase by 40%-, which can reduce the storage capacity and save transportation costs.

4. Good liquidity and easy management. Many powders, especially fluffy feeds with small specific gravity, often stick to feed silos with molasses or high fat and urea-added feeds. Because pellet feed has good fluidity and seldom has adhesion phenomenon, pellet feed is popular for those farms that use automatic feeders to raise dairy cows or poultry on a large scale.

5. Avoid automatic grading of feed ingredients and reduce environmental pollution. In the process of powder storage and transportation, due to the different volumes and mass of various powders, it is easy to produce classification. After the pellets are made, there is no classification of feed ingredients, and the pellets are not easy to dust. During the feeding process, the pellets have much less pollution to air and moisture than powders.

6. Kill Salmonella in animal feed. Salmonella will remain in animal tissues after being ingested by animals. People who eat animals infected with this bacteria will suffer from Salmonella gastrointestinal problems. The method of pellet feed after high-temperature tempering and then pelletizing can kill Salmonella in animal feed.
