Floating Fish Feed Extruder Machine Introduction
A floating fish feed extruder machine is a kind of fish feed pellet processing equipment, it is suitable for large and medium fish feed mills and aquaculture farms. Nowadays, fish feed pellets are more and more popular with the fish farmers, they can provide balanced nutrition and easy digestion and absorption for fish, and many farmers tend to buy a fish feed pellet extruder machine produce fish feed pellets by themselves to low the cost. At the same time, due to the fish feed pellets have high profit and large market space, many pellet choose to start a fish feed pellet business through building a fish feed mill. A wet single screw extruder is the ideal equipment when making floating fish feed.
Here RICHI fish feed extruder machine is recommended for fish feed pellet production, which is the ideal pellet machine in processing fish feed pellets.
- Final feed pellet size : 0.9mm~15mm
- Capacity：1-12T/H
- Raw materials: rice straw meal, soybean cake, peanut cake, corn protein powder, rice bran, bran, acacia leaf powder, and so on.
Working principle and video of floating fish feed extruder machine
During the process of processing fish feed pellets, the powdered feed raw materials are fed into the extruder machine, and the volume of the extrusion chamber gradually decreases along the moving direction of the material, and the expanding pressure of the material gradually increases.
At the same time, the movement of the material in the extrusion chamber is accompanied by strong shear, rubbing and friction.
After a continuous process of mixing, tempering, heating, pressurizing, extruding out of the die holes, sudden rumbling, as well as cutting into pellet segments, drying, stabilizing, etc., the fish feed pellets are finally produced.
technical peremeters of floating fish feed extruder machine
Floating fish feed extruders are super important for feed processing. Whether you’re running a small or medium farm raising grass carp or sea bass, or a big fish feed factory, you need this machine to make feed that stays afloat steadily on the water. There are mainly two types: twin-screw and single-screw. They have different structures, so they fit different production needs. But both can make pellets quickly and the feed floats really well—no wonder they’re so commonly used in the aquaculture industry.
Single screw floating fish feed extruder machine
This extruder is particularly suitable for small farms or small scale fish feed plant, and is a popular choice. It relies on a single screw, using high temperature and high pressure to “expand” the raw materials into floating pellets that are precisely targeted by fish. The equipment is simple and low-cost, making it perfectly adequate for making conventional grass carp and silver carp feed. It can be processed in two ways: dry type fish feed extruder and wet type fish feed extruder. Below is a table of the equipment’s specific parameters:
| Parameters | Dry extruder machines (DGP Series) | Wet extruder machines (DSP Series) |

Twin screw floating fish feed extruder machine
Processing plants that produce dozens of tons of feed daily to supply multiple large fish ponds in the surrounding area often choose this extruder. It utilizes two screws rotating in unison to produce floating feed. Not only does it offer high production capacity and energy savings, its fully kneading screw ensures uniform pellet size. Coupled with a conditioning device, the feed is more thoroughly cooked, making it easier for fish to digest. Below is a table of specific parameters for this equipment:

What are the parts of floating fish feed extruder machine?
We have already known that floating fish extruder is a fish feed pellet machine that extrudes cereal, corn, fish meal, and other materials into 0.9-15mm fish feed pellets. And it has a lot of advantages. Then I will introduce you to the main parts of the floating feed extruder machine below.
Feeder
The feeder is connected with the feeding barrel to prevent caking and ensure uniform and stable feeding. And it is variable frequency speed feeder, can adjust the feeding speed, to ensure that the fish feed pellet extruder can work at maximum power to accomplish the expected output. The feeder of RICHI fish feed extruder machine uses Siemens speed motor to control speed and change material feeding quantity.
Conditioner
The biggest difference between dry and wet extruders is whether or not there is a consitioner. The two modulation methods are different, wet extruder is usually equipped with a conditioner used to condition the moisture and temperature of raw materials, so that the starch paste, raw materials ripening and maturation.
Extruding chamber
The extruder chamber consists of a extrusion screw, a template, a heating clamp and so on.
Mould for extruder
The mould is the outlet of extrusion chamber, you can obtain fish feed pellets with different diameters and shapes through changing the mould.
Cutting knife
The cutting device can cut the fish feed pellets into desired lengths.
Why using the floating fish feed extruder machine?
- The extruded fish feeds have many benefits. Fish feed pellets can float in water for more than 24 hours, which can not only increase the eating time of fish but also can reduce the eutrophication of water. And the gelatinization degree of can reach 90% or more, which can improve the digestibility of fish.
- Then ,the extruded fish feeds are easy to store and transport, which is very convenient for fish farmers and fish feed manufacturers. And in addition,floating fish feeds can not only improve feed efficiency, but importantly, because they can float in water, farmers can see what the fish are eating, which can avoid overfeeding and reduce feed waste.

fish feed pellet production line working process
If you’re planning to build or want to learn more about floating fish feed production lines, you’ll find that a floating fish feed extruder is an essential piece of equipment. To help you more intuitively grasp the practical application of an extruder, I’ll use a 1-1.2 ton/hour production line as a reference. The fish feed production line mainly consists of crushing and mixing section, extrusion and drying section, cooling and packing section.
01 Crushing and mixing section
First of all, feed the raw materials into the hammer mill to do the crushing section—this step grinds things like corn and soybean meal into fine powder. The pulse dust collector will collect the dust at the feeding port so the air stays clean. After crushing, the crushed materials enter the feed mixer through screw conveyor for mixing. Then they will be delivered to next section.
02 Extrusion and drying section
After mixing, the materials are conveyed to the extruding section through bucket type elevator; the materials are fed into the conditioner through an anti-caking bin screw feeder, then enters the extruding chamber for extrusion. Then the fish feed pellets are extruded from the die holes of the mold.
The extruded materials enter to belt dryer machine for drying The dryed feed will be loaded by wind transport system to next section.
03 Cooling and packing section
After drying, the materials enter the spraying machine for spraying. Then the materials enter the cooling section to cool to room temperature. This prevents moisture from building up inside the package later. Once cooling is done, the wind transport system carries them to the packing section to be packed.
How to choose a suitable floating fish feed extruder machine?
RICHI MACHINERY
When choosing a floating fish feed extruder, many aquaculture customers often ask us: Can the pellets produced by the machine be suitable for their fish? For example, can the machine accurately produce 4-5 mm pellets for grass carp? Choosing the right equipment is actually not complicated. We hope the following analysis will provide guidance for your selection.
From the fish feed pellets
- According to the size of the fish feed pellets. For example, 4-5mm feed pellets will be good choice for feeding adult grass carp.
- According to the type of the pellets. Different kinds of fish have different feeding habits, and there are hard feed pellets, soft feed pellets and extruded feed pellets. You should choose the most suitable feed pellets according to the feeding habit of your fish.
From the machine itself
- The fish feed extruder machine can be divided into dry type fish feed extruder and wet type fish feed extruder from the difference in structure.
- The difference between these two is that the wet type is equipped with conditioners, with large capacity and better quality pellet.
Frequently Asked Questions
working process of floating fish feed extruder machine
The working process of the floating fish feed extruder machine can be divided into three stages.
Feeding stage
At this stage, the main process is transporting and compressing materials. The materials will mix with water to form dough-like objects during conveying and are compressed to fill the screw trough.
Compression stage
At this stage, when the materials pass through the floating fish feed extruder machine barrel during transportation, it is subjected to shearing action and mutual friction with the barrel and screw. The frictional heat generated by this process causes the temperature of the material to rise. And the slot of the screw shallows along the material pushing direction and compressing the material.
Extrusion stage
The raw materials are extruded into fish feed pellets at this stage. The temperature and pressure rise rapidly and the shear force increases, the extrusion pressure can reach 3.0-10Mpa, the temperature can reach up to 120-150 degrees Celsius. The fish feed pellets are extruded from the die holes and enter the atmosphere, then the temperature and pressure suddenly drop.
Which floating fish feed extruder is most suitable for a small farm (around 1 ton/day)?
A single-screw dry-process extruder is sufficient. It has a simple structure, low cost, and requires no steam system. It can be operated by 2-3 people, making it ideal for small-scale farms with a production capacity of around 1 ton/day. It also requires easy maintenance, making it ideal for small and medium-sized farms.
What’s the difference between a floating fish feed extruder and a regular pellet machine? Why are extruders so popular for aquatic feed?
The key is the “expansion” function. Extruders use high temperature and high pressure to expand the raw materials, resulting in a low-density feed that floats on the water and also matures nutrients. Regular pellet machines only press and form the feed, so they can’t produce a floating feed, and the fish won’t digest it as well as expanded feed.
