800-1000 KG/h Floating fish feed Extruder machine

Overview of 800-1000KG/H Floating Fish Feed Extruder Machine

The 0.8-1.0 t/h floating fish feed extruder is a medium-sized machine that balances production capacity, process precision, and formula adaptability.

The 0.8-1.0 t/h output is not fixed; the actual production rate varies based on the feed formula (e.g., starch and oil content), pellet diameter (0.6-8.0 mm), and process requirements (floating or sinking). For example, producing 1.5 mm floating feed may result in an output close to 0.8 t/h, while producing 4.0 mm pellets can reach 1.0 t/h or even higher.

For this capacity range, our company offers two main technical solutions:
DGP-160B Dry Type Extruder
DSP-135B Wet Type Extruder

DGP-160B Dry Type Extruder

— 800-1000 kg/h Steam-Free Fish Feed Production Line Solution

This machine does not rely on an external steam source. It achieves expansion through the heat generated by the mechanical friction of materials during the extrusion process.

The DGP-160B features a relatively simple structure and a small footprint, making it ideal for production sites with low electricity costs or limited steam access. However, its adaptability to raw material moisture and formulas is slightly lower.

The Structure of the Floating Fish Feed Extruder Machine

Essentially, the structure of the fish feed extruder is designed around the continuous process of “conveying → compression → cooking → forming → expansion.” The entire machine features multiple functional modules that work in synergy, ensuring that raw materials are transformed from powder into expanded pellets in a short time.

Ini bukanlah sekadar satu unit peralatan, melainkan sebuah sistem yang sangat terintegrasi antara energi mekanik, energi termal, dan pengendalian proses. Setiap modul struktural secara langsung memengaruhi kualitas pakan akhir dan efisiensi produksi.

1. Sistem Pemberian Pakan

Bertugas memasukkan bahan baku yang telah tercampur secara merata ke dalam tabung secara stabil dan berkelanjutan.
Sistem ini biasanya menggunakan pengendalian kecepatan dengan frekuensi variabel, sehingga laju pengumpanan dapat disesuaikan sesuai dengan kebutuhan kapasitas produksi guna mencegah terjadinya penyumbatan atau gangguan pada aliran material.

2. Sistem Pengondisian (Khusus untuk Ekstruder Basah)

Umumnya digunakan pada mesin ekstrusi basah. Dengan menambahkan uap dan kelembapan ke bahan baku, proses ini berfungsi sebagai pemasakan awal.
Hal ini secara signifikan meningkatkan tingkat gelatinisasi pati dan denaturasi protein, sehingga menjadikannya tahap krusial yang menentukan kualitas pakan.

3. Sistem Ekstrusi (Komponen Utama)

Terdiri dari sekrup dan tabung. Sekrup berfungsi untuk mendorong, memampatkan, dan memotong bahan. Tabung menciptakan lingkungan bersuhu tinggi dan bertekanan tinggi.
Selama proses ini, energi mekanik diubah menjadi energi panas, sehingga terjadi proses pemasakan dan plastisasi.

4. Sistem Pemanas (Tersedia untuk Model Kering dan Basah)

Digunakan untuk membantu mengatur suhu laras.
Tipe Kering: Utama mengandalkan gesekan mekanis untuk menghasilkan panas, dilengkapi dengan pemanasan listrik.
Tipe Basah: Sebagian besar mengandalkan pemanasan uap, sehingga memungkinkan pengaturan suhu yang lebih akurat.

5. Sistem Die

Menentukan bentuk dan ukuran akhir pelet. Dengan mengganti cetakan yang memiliki ukuran lubang berbeda-beda (misalnya, 0,6–8 mm), berbagai spesifikasi pakan ikan dapat diproduksi.

Alat pemotong bertugas memotong kolom bahan yang diekstrusi secara terus-menerus menjadi pelet-pelet yang seragam.

6. Sistem Pemotongan

Dipasang di bagian keluar cetakan. Alat ini mengatur panjang pelet dengan menyesuaikan kecepatan putaran, yang secara langsung memengaruhi penampilan dan keseragaman produk akhir.

7. Sistem Penggerak

Termasuk motor, reduktor, kopling, dan sebagainya. Komponen ini menghasilkan tenaga keluaran yang stabil ke sekrup dan merupakan kunci untuk memastikan pengoperasian peralatan yang stabil dalam jangka panjang.

8. Sistem Pengendalian

Digunakan untuk pengendalian terpusat terhadap parameter operasi peralatan, seperti kecepatan pengumpanan, kecepatan unit utama, dan suhu. Model kelas atas mampu melakukan pengendalian otomatis, sehingga meningkatkan stabilitas dan konsistensi produksi.

Fish Feed & Pet Food Extruded by Our Feed Extruder Machine

Backed by mature and stable extrusion technology and flexible formula adaptability, our feed extruders are capable of producing a wide range of aquatic feed and pet food.

From floating and sinking fish feed in various specifications, to pet food with uniform pellets and excellent palatability, we ensure stable forming and mass production.

Through precise control over expansion, pellet density, and appearance, the final products deliver optimal performance in water stability, palatability, and nutrient utilization.

various feed pellets

The extrusion process for fish feed is far more than simple shaping. It is a systematic engineering process comprising multiple stages: conveying, mixing, conditioning, extrusion, expansion, cutting, drying, and coating.

The process parameters of each stage—including temperature, pressure, moisture, and time—directly impact the final feed quality.

The following section provides a complete breakdown of this process chain, helping you understand how high-quality extruded feed is produced.

Receive various powdered raw materials (fish meal, soybean meal, corn flour, wheat flour, etc.). Use vibrating screens and magnetic separators to remove large impurities and metal foreign objects, protecting the safe operation of downstream equipment.

Grind raw materials to over 80 mesh (fineness approx. 0.18mm). This ensures complete starch gelatinization and uniform protein denaturation during subsequent conditioning and extrusion. Grinding fineness directly affects the expansion ratio and water stability of the feed pellets.

Weigh raw materials according to the formula ratio and feed them into the mixer. This ensures uniform distribution of all components, guaranteeing consistent nutrition in every pellet.

Feed the mixed material into the extruder. Under high temperature, high pressure, and high shear, the starch gelatinizes, proteins denature, and the material melts before being extruded from the die.

As the external pressure drops suddenly, moisture instantly vaporizes and expands, forming a porous, fluffy structure. This process simultaneously completes cooking, shaping, and sterilization, making it the critical step that determines the product’s palatability, shape, and quality.

The freshly extruded expanded pellets have high moisture content. They must be passed through a dryer to reduce the moisture to below 10%, making them suitable for storage and transportation.

Dried pellets enter the coating machine, where heat-sensitive ingredients like oils, vitamins, and probiotics are added. Since these ingredients cannot withstand high temperatures, they must be added after extrusion and drying.

The coated pellets are still hot and must be cooled to 3-5°C above room temperature using a counter-flow cooler. This also further removes surface moisture. The cooled pellets become crisp and hard, making them less prone to breakage and easier to package and store.

Finished products pass through a vibrating screen to remove fine powder and irregular pellets, ensuring uniform particle size.

They are then weighed and sealed by an automatic quantitative packaging scale, ready for warehousing or shipment. The collected fine powder can be recycled back into the production line.

Standard Configuration List for the 800-1000 kg/h Fish Feed Production Line

The 800-1000 kg/h fish feed production line is a high-efficiency, complete equipment solution designed for large-scale aquaculture. Its core objective is to stably produce pellet feed that meets the nutritional needs of fish at different growth stages.

With the extrusion system as the core, the entire line is standardly configured around key stages: raw material handling, conditioning and cooking, forming and drying, and post-processing. While meeting the requirements for conventional fish feed production, the equipment combination can also be flexibly adjusted based on the formula type (floating/sinking feed) and the customer’s actual operating conditions.

The following is the typical equipment configuration list for this capacity range, helping you quickly understand the composition and functional layout of the entire line.
