This project concerns a common carp feed pellet extruder in Hungary. The customer involved in this project was not building a completely new fish feed production line. Instead, the company already operated a conventional sinking fish feed workshop producing mash feed and simple pressed pellets for carp ponds.
Common Carp Feed Pellet Extruder in Serbia has become an important equipment investment for freshwater aquaculture businesses looking to improve feed quality and reduce dependence on imported floating fish feed.
This particular project came from a commercial aquaculture feed processor located near the Danube river basin, where common carp farming continues to play a major role in regional fish production and pond aquaculture operations.
The customer involved in this project was not building a completely new fish feed production line. Instead, the company already operated a conventional sinking fish feed workshop producing mash feed and simple pressed pellets for carp ponds.
However, with increasing demand for better feed conversion ratios and improved water stability, the customer decided to purchase a standalone fish feed extruder machine to upgrade feed processing quality while continuing to use the existing grinding, batching, and mixing systems already installed in the facility.

Serbia has a long tradition of carp farming, especially common carp production in pond-based aquaculture systems. Many farms still rely on grain-heavy feeding methods using wheat, corn, and farm-made mash feed. While these traditional feeding practices remain common, larger aquaculture operators have gradually started moving toward extruded fish feed because of several advantages:
Improved digestibility
Better floating stability
Reduced feed waste
More stable pellet size
Higher feed hygiene standards
Lower pond pollution levels
The customer operating this project had previously purchased floating feed from neighboring countries, but transportation costs and inconsistent supply schedules created operational pressure during peak fish growing seasons. Rather than immediately investing in a complete automated extrusion line, the company decided to begin with a single wet type feed pellet extruder integrated into the existing workshop.
The main goal was to produce high-quality floating and slow-sinking common carp feed pellets locally while keeping raw material flexibility.
Before purchasing this Common Carp Feed Pellet Extruder in Serbia, the customer already had:
The weakest part of the operation was feed shaping and cooking. Traditional pellet mills could produce sinking pellets, but the final product lacked expansion performance and water stability required for more modern carp farming systems.
The customer therefore started searching specifically for:
common carp feed extruder
fish feed extrusion machine
floating fish feed extruder
aquafeed pellet extruder
fish feed pellet making machine
The objective was not only producing common carp feed. The customer also planned to test feed formulations for grass carp, catfish, ornamental pond fish, and juvenile carp fingerlings during different seasons.
After technical discussions with RICHI engineers, the customer finally selected a wet process single screw extruder instead of a dry type fish feed extruder.
Several reasons influenced this decision.
First, the customer needed more stable starch gelatinization because common carp feed formulas in Serbia contain relatively high proportions of wheat and corn. Wet extrusion improves cooking quality and pellet stability under these conditions.
Second, the customer planned to produce floating feed with better expansion control for different fish growth stages.
Third, the customer already had access to steam generation infrastructure from previous feed processing operations, making wet extrusion more practical.
Dry type fish feed extruders are often suitable for smaller independent farms or lower-capacity operations. In this project, however, the customer wanted more flexibility for commercial feed production.
After evaluating production targets, workshop size, local electricity conditions, and expected market expansion, RICHI recommended the following model.
This model offered the right balance between production scale and operational flexibility for medium-sized freshwater aquaculture feed manufacturing.
| Item | Specification |
|---|---|
| Model | DSP-135B |
| Main Motor Power | 75kw |
| Feeding Power | 7.5kw |
| Conditioning Power | 2.2kw |
| Cutting Power | 1.5kw |
| Screw Diameter | 135mm |
| Machine Dimensions | 3750×1980×1950mm |
| Production Capacity | 0.8-1.0T/H |
The customer considered this capacity ideal because it matched the scale of regional pond aquaculture demand without creating excessive inventory pressure.
One important aspect of this Common Carp Feed Pellet Extruder in Serbia project was raw material flexibility. Serbia has strong agricultural production, especially grain cultivation, which gives local feed producers access to relatively affordable feed ingredients.
The customer’s common carp feed formulations mainly included:
For juvenile carp feed, protein levels were adjusted higher by increasing soybean meal and fish meal ratios.
For adult common carp feed, grain proportions increased significantly because pond carp in Serbia are often raised using semi-intensive feeding systems.
The final pellet sizes produced by the fish feed extruder included:
This flexibility allowed the customer to supply different pond operators throughout the growing season.
Compared with traditional sinking mash pellets, the new floating and slow-sinking feed produced by the DSP-135B extruder offered several operational improvements.
Farm operators could observe feeding activity more clearly because floating pellets remained visible on the pond surface. This helped reduce overfeeding and improved feed management efficiency.
The extruded pellets also showed stronger water stability, reducing nutrient losses before fish consumption.
Another important advantage involved transportation and storage. Because the pellets were more uniform and durable, packaging damage decreased noticeably during distribution to fish farms across Serbia and neighboring Balkan regions.
The customer also started testing higher-end aquafeed formulations after installing the new fish feed extruder machine.
Although this project centered around Common Carp Feed Pellet Extruder in Serbia, the equipment itself is highly versatile.
With relatively small adjustments to screw configuration and formulas, the same machine can also produce:
This versatility became one of the customer’s main reasons for selecting the DSP series wet fish feed extruder.
The customer especially appreciated the possibility of producing seasonal specialty feeds without purchasing additional pelletizing equipment.
One reason the customer trusted RICHI Machinery was the detailed communication before production even started.
RICHI engineers analyzed:
Raw material characteristics
Target pellet buoyancy
Feed density requirements
Desired expansion ratios
Local aquaculture feeding habits
Protein level adjustments
Steam conditioning requirements
Instead of simply recommending the largest fish feed extruder available, RICHI proposed a model that matched the customer’s actual production stage and future expansion plans.
Several feed samples were also discussed in detail to optimize screw configuration and die selection.
The Common Carp Feed Pellet Extruder in Serbia was shipped from Qingdao Port.
Since Serbia is a landlocked country, the equipment arrived through:
Port of Bar, Montenegro
This route is commonly used for industrial equipment imported into Serbia and surrounding Balkan regions.
After arrival, installation moved relatively smoothly because the customer already had part of the workshop infrastructure prepared.
RICHI provided:
During the first weeks of operation, several carp feed formulations were tested to determine the best balance between floating performance and pellet density.
Particular attention was given to moisture levels before extrusion because common carp feed in Serbia often contains relatively high cereal content compared with marine fish feed.
Several months after commissioning, the customer reported that the new wet fish feed extruder significantly improved pellet consistency and feed appearance.
The customer especially highlighted:
More stable pellet expansion
Better floating duration
Reduced feed powder during transportation
Improved flexibility for different feed sizes
The customer also appreciated that the machine remained relatively easy to operate despite producing multiple feed formulations.
According to follow-up communication, local fish farms responded positively to the new feed texture and improved water stability.
RICHI Machinery has already exported fish feed pellet extruders, floating feed machines, aquafeed extrusion systems, and aquatic feed processing equipment to dozens of countries worldwide.
Different customers process different feed products depending on local aquaculture industries, including:
Because of this experience, RICHI Machinery can adapt fish feed extrusion solutions according to local raw materials, fish species, feeding habits, climate conditions, and production scale requirements.
For many regional feed producers, investing in a properly configured fish feed extruder has become one of the most effective ways to improve feed quality while maintaining local raw material flexibility.
