Pellet Feed Vs Extruded Feed in Process, Cost and Application

Aquatic mixed feed can generally be divided into pellet feed and extruded feed, so as for crayfish feed (pellet crayfish feed and extruded crayfish feed). Then what’s the difference between pellet feed and extruded feed?

Difference in Feed Making Process

First of all, let's look at the their differences in the feed manufacturing process. (How to make cattle feed pellets? )

Fish Feed Pellet Making Process

The processing flow of making pelleted fish feed generally includes crushing, mixing, pelletizing and cooling. The pellet size is decided by the diameter of pellet die. You can make fish feed pellets with different sizes by changing the pellet die.

Two Tips for Fish Feed Processing

The performance of the crusher will determine the grinding fineness of raw fodder materials.
The temperature of the crushed feed in conditioner is about 80-90 degrees. At this temperature, the feed powder can reach the semi-curing stage, so that the final produced fish feed pellets are also in semi-curing stage.

Extruded Fish Feed Making Process

Lately a small to medium scale floating fish feed production line had arrived in Ecuador. The manufacturing process of extruded fish feed is generally the same as pelleted fish feed. But there are three differences:

The fineness of fodder material after crushing is finer than that of pellet feed.
The temperature of feed extruding chamber in fish feed extrusion machine can reach up to 110-200 degrees. Extruded fish feed is produced under high temperature and high pressure, through the process of mixing, tempering, heating, curing, extruding, discharging.
The water content of extruded or expanded fish feed is much lower than that of pelletized feed. Due to the water lost in the process of high temperature and high pressure, 1.1 tons of raw feed materials can only made about 1 ton of extruded feed products.

Difference in Property under Water

For granulated or pelleted feed, to ensure the stability under water, it is necessary to add a lot of adhesives such as high-gluten flour or other animal absorbable adhesives. While not needed for extruded feed pellets. Since extruded feed is cured, it can transform into swelling state like a sponge in the water.

Other Differences Between Compressed Feed Pelles and Expanded Feed

Difference in Dust Content: Pelletized feed has more dusk content than extruded feed.
Difference in Feed Processing Cost: The production cost of extruded (expanded) feed is 1-1.5 times that of pellet feed.
Difference in Nutrition Absorption for aquatic animal: The extruded fish feed is produced under high temperature and pressure which can eliminate the bacteria and improve the feed taste, so extruded feed is better than pelleted feed in nutrition absorption for fish and other aquatic animals.
Difference in Price of Feed Processing Machine: The price of extruded feed making machine is generally higher than normal feed pellet machine. Therefore, feed extruder machine is usually used to make high-grade fish feed.

Fish feed extruder machine is used for processing pellet feed. It is mainly feed raw material by aquaculture granulator after processing into granule. The benefit of pellets is that they reduce feed wastage and kill a lot of bacteria in high-temperature press, so the health is saved. (Read more about floating fish feed extrduder machine)

Normal growth of fish requires a sufficient amount of protein in the feed, easy to digest and absorb, and suitable proportion of various amino acids.When fish intake protein insufficiency, growth is slow, body immunity drops, various amino acid proportion suitable protein.When fish intake protein insufficiency, growth is slow, body immunity is reduced, tissue renewal is slow, wound healing strength is poor, susceptible to disease.

We know that fish feed is soaked in water for fish to eat, so it needs to be water resistant. The average good fish feed can be water-resistant for up to 3-6 minutes, giving the fish more time to eat. The use of pellet feed completely avoids these problems. Digestive enzymes secreted in high-temperature pressing can effectively improve the digestive ability and diet of animals. So if you use granules in farming, you can effectively improve the efficiency of fish farming.

In general, the more the fish feed, the lower the feed coefficient, the higher the absorption rate. It is also easier to feed on fish and avoid indigestion. Therefore, when machining with fish feed equipment, the smallest mold plate, such as 2mm or 2.5mm, is selected for fish consumption. Here is an article about starting a fish feed production line.
