Pellet feed pk puffed feed?

There are two kinds of aquatic compound feeds, one is pellet feed, and the other is expanded pellet feed, referred to as expanded feed. The same is true for crayfish feed. There are currently two types of crayfish feed on the market, one is crayfish pellet feed. The other is crayfish puffed feed. What are the differences between the two feed processes and properties? bpA China Feed Industry Information Network - based on feed, serving livestock

Crayfish pellet feed: The production process is basically: first, the different raw materials are crushed by a pulverizer, and then the raw materials are mixed by a raw material premixer, and the mixed raw materials are semi-finished products of crayfish compound feed, followed by the process of making granules. The premixed compound feed enters the mechanical conditioner and then the ring membrane presses the particles! The diameter of the ring membrane is the diameter of the feed. Different sizes of pellet feed are produced, and the pellets of different diameters are used to extrude the pellet feed. Is the finished pellet feed! bpA China Feed Industry Information Network - based on feed, serving animal husbandry

There are two important points: First, the performance of the crusher will determine the fineness of the raw material. Second, the temperature of the pulverized powder feed into the conditioner is about 80-90 degrees. At this temperature, the powder can be semi-cooked, and the final tempered powder is extruded into a pellet feed through a ring membrane. Therefore, the pellet feed is a semi-cooked material. bpA China Feed Industry Information Network - based on feed, serving animal husbandry

First, the puffed feed bpA China feed industry information network - based on feed, service animal husbandry

The manufacturing process of the expanded feed is generally the same as that of the granules, but the expanded feed has two more procedures than the granule feed process. First, it is pulverized twice before the granules are produced, that is, the ultrafine pulverization, the fineness ratio of the raw material powder. The pellets are finer. The second is the puffing machine. The temperature of the feed material in the extrusion chamber is as high as 110-200 degrees, high pressure, environment, continuous mixing, quenching and tempering, heating, pressurization, curing, extrusion, and extrusion after the film hole is suddenly reduced. Loose porous pellet feed. bpA China Feed Industry Information Network - based on feed, serving animal husbandry

In addition, the moisture of the extruded feed is much lower than that of the pellet feed, because in the process of high temperature and high pressure, the water is lost, and 1.1 tons of powdered raw material is made into pellets with only about 1 ton of finished extruded feed. bpA China Feed Industry Information Network - based on feed, serving animal husbandry

Second, the nature of water into the bpA China feed industry information network - based on feed, service animal husbandry

In order to ensure that the water is not allowed to enter the water for a long time, it is necessary to add a large amount of binder such as high-gluten flour or other animal-absorbable binder to achieve long-lasting effect. The puffing machine is not used. Because it is purely mature, it can become a bulky state when it enters water for several hours, just like a sponge. bpA China Feed Industry Information Network - based on feed, serving animal husbandry

Third, the dust bpA China feed industry information network - based on feed, service animal husbandry

Pellet feed dust is significantly more than puffed feed. bpA China Feed Industry Information Network - based on feed, serving animal husbandry

Fourth, the process of manufacturing costs bpA China feed industry information network - based on feed, service animal husbandry

The cost of making a puffed feed is 1-1.5 times the cost of pelleted feed. bpA China Feed Industry Information Network - based on feed, serving animal husbandry

Fifth, the absorption problem bpA China feed industry information network - based on feed, service animal husbandry

The extruded feed is subjected to high temperature and high pressure to eliminate a large number of bacteria, and the taste is good, and the absorption must be better than the raw material pellets. bpA China Feed Industry Information Network - based on feed, serving animal husbandry

Sixth, the market price bpA China feed industry information network - based on feed, service animal husbandry

Because the price of puffing machinery and the cost of process cost are much higher, the price of puffed feed is generally higher than that of pellet feed, and puffing is generally made into high-grade fish feed. bpA China Feed Industry Information Network - based on feed, serving animal husbandry

According to the actual situation of puffing and pellets, comprehensive price, sensory perception, actual feeding effect, choose a feed that is most suitable for you. bpA China Feed Industry Information Network - based on feed, serving animal husbandry
