Leave Us a Message

“Floating Fish Feed Machine” is equipment used to produce floating fish feed pellets.

Raw materials are mixed, cooked, and expanded inside the extruder, ultimately forming buoyant pellets that can float on water for a certain period, making it easy for fish to eat.

Floating fish feed usually requires high expansion, uniform density, and stable shape to ensure feed utilization efficiency and feeding effectiveness for the fish population.

RICHI provides two types of floating fish feed machines for production needs for various scales and product types:

Complete Floating Fish Feed Production Process

In addition to floating fish feed extruder machine, feed mills, medium or large-scale aquaculture plants are usually equipped with a complete aqua feed production line to produce aqua feed, which can not only get high-quality aqua feed, but also improve work efficiency, so that the feed mill can achieve maximum benefits.

As professional floating fish feed machine manufacturer, RICHI has designed turnkey floating fish feed production lines for thousands of customers. We can provide you with customized floating fish feed production line solutions according to the specific needs of each customer.

The standard floating fish feed production line’s process flow is as follows: crushing – mixing – extrusion – drying – spraying – cooling – packaging. (Not every feed production project requires all of these steps. All our steps are modularly designed and can be added or removed according to your specific needs.)

1 Crushing

Finely crush all types of raw materials to achieve uniform and smooth particle size.

2 Mixing

Blend main ingredients with various nutritional additives, ensuring consistent composition in every batch.

3 Pelleting/ Extrusion

After conditioning, the materials are pressed under high pressure to form dense, smooth pellets with good water stability, meeting the requirements for sinking feed.

4 Drying

A gentle and controlled drying process effectively reduces the moisture content of the pellets, preventing mold growth during storage while preserving heat-sensitive nutrients as much as possible.

5 Spraying

Evenly spray oil or functional liquid additives onto the pellet surface. This not only boosts energy density and palatability but also enhances immune support and growth performance.

6 Cooling

Gradually cool freshly dried hot pellets to near room temperature. This prevents condensation caused by temperature differences, ensuring stable product quality during packaging and storage.

7 Screening

Remove debris and irregular particles generated during production, retaining only standardized finished products. This ensures even feeding distribution and reduces waste.

8 Packaging

Use an automated packaging system to seal the finished feed in bags for easy transportation, storage, and end-use.

① Crushing

② Mixing

③ Pelleting / Extrusion

④ Drying

⑤ Spraying

⑥ Cooling

⑦ Screening

⑧ Packaging

FAQ About Floating Fish Feed Making Machine

If you have any questions about floating fish feed equipment and floating fish feed production, you can first take a look at these answers.

1. Why can’t grease be added directly into the mixer, but must be sprayed using spraying Equipment?

+

In principle, oils and fats can be added to the mixer and mixed with the raw materials. However, the fish feed extruder machine has strict requirements on the fat content in the raw materials during expansion and extrusion. When using a single screw extruder machine to produce aquatic feed, it is recommended that the fat content in the raw materials should not exceed 8%; when using twin screw extruder machine to produce aquatic feed, it is recommended that the fat content in the raw materials should not exceed 15%.

Therefore, in order for the fish feed extruder machine to work properly, the oil cannot be added directly into the mixer, but needs to be sprayed onto the surface and inside of the extruded feed using a sprayer after the extrusion is completed.

2. If the feed formula contains some heat-sensitive raw materials, they will be destroyed by high temperature during feed extrusion. What should we do in this case?

+

The temperature in the fish feed extruder machine is relatively high, for example, for a twin-screw extruder machine, it can even reach 200 degrees. High temperature can improve the maturity and sterilization of materials, but at the same time, if the feed formula contains heat-sensitive raw materials, such a high temperature will cause certain damage to the heat-sensitive raw materials.

In this case, the heat-sensitive raw materials can be added directly to the oil to be sprayed without passing through the fish feed extruder machine, and then sprayed onto the surface and inside of the feed through the spraying machine.

3. Is it necessary to have a boiler to produce extruded fish feed?

+

The boiler is not a must. The main function of the boiler is to provide hot steam to the modulator of the fish feed extruder machine to improve the maturation of the material.

However, fish feed extruder machine are divided into dry feed extruder machine and wet feed extruder machine. There is no regulator on the dry extruder, so there is no need to equip it with a steam boiler to provide hot steam.
