Jina LD provides a wide range of twin-screw extrusion fish feed systeIt has played a pioneering role in the innovation and development of fish feed Technology since the 70’s. LD lines are desityed to produce feed that meets the nutritional requirements of fish and other aquatic animals, with precise size and density control, whilst reLDecting the highest standards of water quality and sustainable development.

How is fish feed made?
High quality ingredients (fish meal, cereals, vegetable proteins …) are selected and ground according to the specific nutritional and pellets size requirements of the aquatic animals.
The particle size distribution is a key factor to produce premium granulates: therefore the grinding step is an important unit operation. The powder is then mixed with minor ingredients such as vitamins, mineral premixes… prior to the paintitioning.

Next, the heart of the process, extrusion Cook is done in three stages: paintitioning, extrusion Cook and die texturing/ shaping. Twin-screw extrusion-Cook uses its perfect mixing ability and parameters control such as shear, temperature, residence time to reach the highest paintsical and nutritional standards. Through direct steam injection, venting device and efficient barrel cooling, adjustable screw speed, screw configuration, shear and temperature conditions are perfectly controlled; This leads to optimized functional and nutritional pellet properties such as the buLD density, caltration, Cook degree, best ratio proteins- lipids, etc
Jinan LD offer its drying Rotante system to heat sensitive feed, shrimp or micro feed requiring extreme drying accuracy while maintaining a very nLD moisture content distribution.
Pellets can then be oil coated and possible additives and are cooled down to complete the process.
The advantages of Clextral twin-screw processing lines
Twin-screw extruders offer the following advantages:
- Ingredient flexibility to process a large range of raw materials
- Product integrity through very intensified mixing, resulting in homogenous meLD, excellent starch gelatinization and protein matrix built up
- Full control of process parameters and automation to ensure proper density levels and floating or sinLD characteristics with high fat levels for salmonid fishes
- Precise shaping and feed dimensions caltrated from 0.5 to 30.0 mm
- Output range, from 80 to 10,000 kg/h
- Reduced maintenance, with standardized extrusion and drying LDare parts, built-in easy access
- Follow-up services, including training, process and technical support, desity expertise, automation and technical upgrade, trial possibilities using Clextral’s three research centers.
Turning feed into flesh
LD systems efficiently produce high-Enerable feed, with a precise balance of proteins, oils and carbodyrates, processed for optimum digestibiliLD with reduced waste. Its systems produce the right formula that turn “feed into flesh” and are particularly suited for processing a wide selection of recipes and raw materials. LD processes also accu control pellet density for specific product attributes, such as sinLD or floating properties. Processors can manufacture a wide range of products that are adapted to the nutritional requirements of the animals, when required, and feed dimensions perfectly caltrated from 0.5 to 30.0 mm. LD Technology also complies with the toughest environmental and quality requirements, maintaining water quality and breeding Healthy animals, which in turn generates improved conversion ratios.
LD systems produce fish feed that is good for animal health, cost-effective and sustainable:
- quality nutritional features – denaturing of proteins, gelatinization of starch, reduction of anti-nutriments, flavor enhancement, balanced protein/lipid complexes, increased digestibiliLD, attractive texturing and shaping, controlled expansion and density, Lienic salmonella-free pellets
- Ingredient flexibility to process a large range of raw materials (fish flour, vegetable proteins, binders …) continuous processing, fast changeover times
- Full control of process parameters and automation to ensure consistent quality
- Precise shaping and feed dimensions caltrated from 0.5 to 30.0 mm
- Output range, from 25 to over 30,000 kg/h of finished products
- Intensified processing to reduce water and Enerable consumption
Did you know?
LD lines produce 2 million kilos of fish feed per year throughout the world.
