APPLICATION OF Fish Feed Extruder
RICHI fish feed extruder machine is a versatile aquatic feed production machine for making aquatic feed. It works great for fish, shrimp, crab, shellfish, soft-bodied animals, turtles, and even pet food like cat/dog.
When making feed with a fish feed extruder, different ingredient recipes directly impact the pellets’ nutritional value and water stability. To ensure good pellet formation, you must adjust the raw materials based on the fish or shrimp or pet species, growth stage, and farming conditions.
Extruded Shrimp Feed Production with fish feed extruder
It can produce shrimp feed pellets that sink to the bottom of the water and can remain in the water for a long time without being easily deformed, so as to meet the production needs of different types of shrimps and crabs.
Extruded Pet Food Production with Fish Feed Extruder
RICHI fish feed extruder can produce pet food in different shapes and sizes to meet the feeding needs of some pets such as cats, dogs, turtles, etc.
Extruded fish feed production With Fish Feed Extruder
For fish feed extruders, two common choices exist: If your needs are simple, you can purchase this equipment alone and use it to complete the feed pelletizing. If you need to build a large-scale feed production system, you can also integrate it into a complete fish feed production line as a core component of the feed processing plant, working with other processes.

Fish Feed Extruder: BUILDING Your Complete Aquatic Feed Production SOLUTION
In the fish feed production, a single fish feed extruder machine can’t handle the entire process alone. It often works with crusher, mixer, dryer, sprayer, cooler and packaging equipment to form a complete fish feed production line.
The production line specifically includes raw material reception/processing, crushing, mixing, extrusion, drying, spraying, cooling,screening, and packaging sections.
This setup is flexible. They can be flexibly added or removed based on needs. In some cases, the extruder can even be replaced with a pellet mill to further adapt to different production requirements.
Pre-processing
Use a powder material cleaning sieve to remove fine sand, small stones, metal debris, dust clumps, etc., and meanwhile break up slightly agglomerated material.
Crushing
Granular raw materials need to be crushed before extrusion. Depending on production needs, an ultra-fine grinder can be used for secondary crushing.
Mixing
According to the feed formula, the crushed materials and the vitamins, premixes, oils, etc. that need to be added are sent to the feed mixer for uniform mixing.
Extrusion
The mixed ingredients are processed with high temperature, pressure, and moisture inside the fish feed extruder. This cooks them thoroughly and kills bacteria.
Drying
Dryer dries the moisture content of feed pellets to between 10% and 11%, which is convenient for subsequent processing and can be stored for a long time.
Spraying
The dried puffed feed pellets are sprayed through a spray device to increase the fat content in the puffed feed pellets and improve the palatability of the feed pellets.
Cooling
Lowering the feed pellet temperature to near room temperature. This helps evenly distribute moisture and prevents cracking or condensation.
Packaging
Using fully automatic packing equipment, finished feed pellets can be packaged into bags for easy storage, transportation and sales.

FAQ ABOUT FISH FEED EXTRUDER
If you have any questions about extruders or feed production, you can first take a look at these answers.
1. What types of fish feed extruders do you offer?
+
We offer different kinds of fish feed extruders to fit different needs.
We have dry extruders that don’t use steam, which are good for making floating feed. We also have wet extruders that use steam to cook the feed better, for higher quality output.
If you need different levels of production, we have single-screw models for small or medium output, and twin-screw models for large output or feeds with high fat or special formulas.
2. What raw materials can be used with your fish feed extruders?
+
Our fish feed extruders can use many different raw materials.
Common ingredients are fish meal, soybean meal, and insect protein for protein. Corn, wheat, and rice bran are often used for energy.
You can also add oils like fish oil or plant oil to give the feed more energy. Vitamins, minerals, and binders can be added too, to make the feed more nutritious and hold together better.
3. How should I choose the right fish feed extruder ?
+
First, think about how much feed you need to make each hour.
Next, decide what type of feed you want — floating, sinking, or high-fat.
Also, choose the level of automation: manual control or automatic with a PLC system.
Finally, pick the machine that fits your budget and gives you good value.

6. What is the fish feed extrusion process?
+
The commercial fish feed extrusion process, in simple terms, involves using a fish feed extruder to apply pressure, heat, and moisture to pre-mixed feed ingredients within a short time for processing.
There are two main heating methods: one relies on frictional heat generated by the machine (called dry extrusion), while the other involves preheating the ingredients before injecting steam (called wet extrusion).
This process can handle common raw materials like soybeans, corn, rice, and peas, as well as high-moisture content ingredients. It mainly includes two types: dry type and wet type.
Dry extrusion process: During processing, no additional water or steam is added. Heat is entirely generated through mechanical friction, while the screw applies pressure to force the ingredients out of the die mold. Once extruded, the sudden drop in pressure causes the moisture in the ingredients to evaporate. Throughout this process, the moisture content of the ingredients remains between 15% and 20%.
Wet extrusion process: The principle is similar to that of dry extrusion, but it requires additional water and steam injection, raising the moisture content of the ingredients to 20% or even above 30%, since heating primarily relies on the injected steam.
