Commercial Shrimp Feed Pellet Mill Project in Egypt
The customer is a large aquatic feed processing group in Egypt. Its main raw materials include locally sourced barley, wheat bran, and sunflower meal. RICHI supplied an SZLH768 feed pellet mill and integrated it into the customer’s existing production line, which reached a capacity of 8 t/h.
The machine supports flexible combinations of grains and protein ingredients. For different product requirements, RICHI supplied three ring die specifications. By changing the ring die, the customer can produce 1/1.5/ 3 mm shrimp feed pellets. RICHI also helped set suitable compression ratio parameters.
The customer can now use the machine to produce Pacific white shrimp, tilapia, and European sea bass feed. The feed formula can be switched between shrimp and fish feed according to production needs, allowing one machine to handle multiple products.
Building a Complete Shrimp Feed Production Line
Some customers upgrade to a complete shrimp feed production line after purchasing a shrimp feed pellet mill. RICHI also provides complete production line solutions from raw material processing to finished product packaging. Here’s a look at the typical process flow of a complete shrimp feed production line.
Raw Material Cleaning
Corn, wheat, soybean meal, fish meal, and other ingredients first pass through a pre-cleaner and permanent magnet. These machines remove stones, metal, and other impurities to keep the raw materials clean and protect downstream equipment.
Primary Grushing and Batching & Mixing
A grinder first reduces larger raw materials to a suitable size. The ingredients are then batched and mixed according to the shrimp feed formula. Thorough mixing distributes different ingredients evenly and prepares the material for further processing.
Secondary Grushing
The mixed batch enters a superfine grinder for further size reduction. This brings the ingredients to a particle size more suitable for small shrimp feed pellets. The material then moves directly to the pelletizing bin before entering the conditioning and pelletizing stage.
Conditioning and Pelletizing
This stage takes place in the shrimp feed pellet mill. The material enters the conditioner and comes into full contact with high-temperature saturated steam. After conditioning, it enters the pelletizing chamber, where rollers compress the material against the ring die to form uniform shrimp feed pellets.
Post-Curing and Cooling
For high-end sinking shrimp feed with specific requirements, a post-curing machine can be added as an optional process. The pellets remain in a controlled holding environment for 10–20 minutes. This further promotes starch gelatinization and creates a denser pellet structure, helping improve water stability. The pellets then enter a counterflow cooler for rapid cooling and moisture reduction, which helps stabilize the internal pellet structure.
Screening and Packaging
The finished pellets fall onto a vibrating screen. Undersized particles and fines pass through the lower screen and return for re-pelletizing, while qualified pellets enter the packaging machine for measured filling. For high-end shrimp feed, a coating process can also be added after screening. Depending on the formula, the pellets can be coated with oil, flavoring agents, or other functional ingredients to improve palatability.
Shrimp Feed Pellet Mill FAQs
From equipment selection and production applications to pricing and after-sales support, the following answers address common questions about buying and using a shrimp feed making machine.
What is the difference between a shrimp feed pellet mill and a feed extruder? Which one is right for me?
→
A prawn feed machine uses steam conditioning, roller compression, and ring die forming to produce dense pellets. It is mainly used for sinking shrimp feed. A feed extruder uses high temperature, pressure, and shear to expand the material. It is more commonly used for floating or slow-sinking aquatic feed.
If your main product is sinking shrimp feed and you need good water stability and suitable sinking performance, a ring die pelletizer is usually the better choice. If you plan to produce floating aquatic feed, the right equipment depends on the product type, formula, and processing method. You can also check our floating fish feed extruder page for more information.
How do I choose the right shirimp feed manufacturing machine model?
→
Start by determining your target capacity, such as how many tons of shrimp feed you need to produce per hour. Then provide your raw materials, feed formula, and required pellet size. RICHI engineers will match the machine model and configuration based on these factors rather than recommending equipment based on capacity alone.
Can I use a shrimp feed pellet mill to produce fish feed? How do I switch between them?
→
Yes. With a suitable feed formula and equipment configuration, this machine can also produce some types of sinking fish feed and other aquatic pellet feeds.
When switching between shrimp and fish feed, you typically need to change the ring die according to the required pellet size. You may also need to adjust the formula, conditioning parameters, and pelletizing settings. The Egyptian customer mentioned earlier uses the same pellet mill for both shrimp and fish feed and switches products by changing ring dies with different specifications.
Why does my shrimp feed have poor water stability and make the pond water cloudy?
→
Poor water stability does not necessarily mean there is a problem with the pellet mill. Feed formulation, particle size, steam conditioning, ring die compression ratio, and pelletizing parameters can all affect the final pellet structure and water stability.
If the pellets break apart quickly in water, first check whether the ingredients have been ground finely enough and whether the formula is properly balanced. Then check the conditioning temperature, steam addition, and material retention time. For sinking shrimp feed that requires longer water stability, you can also use a multi-layer conditioner and add a post-curing machine according to the product requirements.
How much does your shrimp feed pellet mill cost? Does the price include shipping?
→
The smallest standard machine starts at about US$7,500. The shrimp feed pellet machine price depends mainly on the machine model, production capacity, main machine configuration, conditioning system, and other optional equipment. Therefore, prices vary between projects.
RICHI usually quotes equipment on an FOB basis, excluding international shipping costs. If you provide your target capacity, raw materials, pellet size, and destination port, we can quote the required configuration and help you estimate the related shipping costs.
What after-sales support do I get after purchasing the machine?
→
RICHI provides a one-year warranty for the complete machine, along with installation guidance, commissioning support, and operator training. After the machine enters production, you can continue to receive long-term technical support. If equipment or production problems occur, our after-sales engineers will help analyze the cause and provide a solution.
During the warranty period, RICHI will handle covered issues according to the applicable warranty policy. After the warranty expires, repairs only incur the cost of replacement parts. Some key components use imported brands, which are also available in local markets. If needed, RICHI can help supply the required spare parts.
In addition, RICHI provides lifetime technical support. Our after-sales team responds to customer questions within 24 hours. If an on-site visit is required, overseas engineers can arrive within 48 hours to assist with equipment installation, commissioning, or operation issues.
