The production of pelleted feed will naturally use pelleted feed equipment. Pelleted feed equipment can be said to be a general term for pelleting, feed grinder, feed mixer, feed pellet machine can be called pelleted feed equipment. These machines can also form a set of Feed Production Line. So, Which equipment do you need for pelleting of feed?
Commonly used equipment for pellet production:
1、Conveying and distribution equipment: It is mainly used to convey raw materials, semi-finished products, and finished products and distribute them to designated stations or silos. Conveying equipment can be divided into two categories: mechanical conveying and pneumatic conveying. The distribution equipment mainly includes three-way, four-way, multi-station rotary distributors and pendulum distributors.
2, cleaning equipment: mainly to remove impurities in the feed materials, especially large and medium impurities and iron impurities, to protect the safety of equipment and people. Cleaning equipment mainly includes screening equipment and iron removal equipment.
3, crushing equipment: It is mainly used to crush feed materials with unqualified particle size to make them meet the requirements of feed particle size. The crushing equipment also has different forms according to the requirements of crushing particle size.
4, batching equipment: is based on the formula’s requirements will be a variety of feed ingredients in turn in a certain proportion with the equipment, batching equipment, and automatic batching and manual batching two types.
5, mixing equipment: It is the equipment that fully mixes the prepared feed ingredients to make it into a powdered feed product with a qualified uniformity of chaos and uniformity. Commonly used in feed mills is intermittent mixing equipment.
6, pelleting equipment: It is equipment for making powdered compound feed into pellet compound feed. There are two types of ring die and flat die. At present, feed mills mainly use ring die pelletizers.
7, cooling equipment: the general temperature of the granulated feed pellets is 80C ~ 90 ℃, moisture in about 16%, must be cooled, water. Cooling equipment through the suction wind to make the material temperature down to close to room temperature, and in the cooling at the same time partly reduce the moisture of the feed.
8, crushing equipment: is the granular feed with broken into small particles (known as crushed grain) machine, generally use the wheel type crusher.
9, grading equipment: crushed particles caused by part of the powder with grading equipment to separate out to ensure the quality of the finished granular material. The separated powder material needs to be sent back to the granulating machine to granulate again.
10, finished packaging equipment: packaging can be divided into automatic packaging and manual packaging two ways. Automated packaging generally uses computer-controlled automatic quantitative scales with infusion machines and seamer. Manual packaging generally uses a scale plus a portable seamer.
11, dust removal equipment: It is a device that sucks dust and protects the environment. The principles and equipment used for dust removal and air transportation are basically the same. The difference is that one is for conveying dust and the other is for conveying materials.
For the production of feed with special requirements, there are the following types of equipment:
1, liquid adding equipment: A device for quantitatively adding liquid raw materials such as grease to the powder in the mixer.
2、Post-curing equipment: The equipment that heats and keeps the pellets coming out of the pellet mill to improve the degree of maturation, which can greatly improve the stability of pellets in water.
3, after the spraying equipment: The fat content in the material before pelleting should not be too large. If there is too much fat added to the feed formula, the excess part should be sprayed on the surface of the pellet feed after the pelleting.
4, puffing equipment: It can produce various aquatic feeds with different densities such as floating, sinking, and flooding, and can also be used as raw material to lake starch and destroy the anti-nutritional factors in soybeans.
5、Drying equipment: Some feed products require low moisture, but the moisture added in the production process is relatively large. If these feed products are not dried, the moisture index does not meet the requirements of the product, so drying equipment must be used to dry them.
Generally speaking, a whole Feed Production Line includes several steps of raw material receiving and storage, cleaning, crushing, batching, mixing, pelletizing, cooling, crushing, screening and packaging. Some feed products with special requirements also require liquid addition, pre-cooking, post-cooking, post-spraying, puffing, and drying processes. You can choose the right equipment according to your needs.
