Components of an Aquafeed Production Line

Equipment	Capacity	Image	Function	Advantages
Hammer Mill	Power: 7.5 kW Capacity: 1000kg/h		Reduces raw materials such as corn, soybean meal, and grains to the required particle size for further processing. Proper grinding improves the consistency of the feed mixture and supports efficient extrusion.	Improved digestibility: Smaller and more uniform particles provide a larger surface area for digestion and nutrient absorption. Better extrusion performance: Consistent particle size promotes more uniform mixing, moisture distribution, and cooking during extrusion. Wide material adaptability: Suitable for processing raw materials with different hardness levels.
corn horizontal mixing machine	Output: 500 kg/batch Power: 5.5 kW		Thoroughly mixes ground raw materials with micro-ingredients such as vitamins, minerals, and other additives to achieve a uniform nutrient distribution throughout the feed mixture.	High mixing uniformity: Rapid and thorough mixing with minimal dead zones and a low coefficient of variation (CV). Efficient operation: Easy feeding, fast discharge, and low material residue help improve production efficiency. Consistent feed quality: Uniform mixing ensures that each batch and finished pellet contains a consistent proportion of nutrients and additives.
wet-type fish feed extruder machine	Capacity: 1.2-1.5T/H Main drive motor: 55 kW Feeding system motor: 2.2 kW Cutting system motor: 1.5 kW Conditioning system motor: 3kW Requires a steam boiler or steam generator.		Uses controlled temperature, pressure, moisture, and shear forces to cook and gelatinize the raw materials. The processed material is shaped through the die and then cut into pellets of the required length.	Effective cooking: High-temperature and high-pressure processing promotes starch gelatinization, improves feed digestibility, and helps reduce harmful microorganisms. Flexible pellet shapes: Different dies can be used to produce various pellet shapes, including round, heart-shaped, and bone-shaped pellets. Wide formula adaptability: Suitable for feed formulas with different oil, moisture, and ingredient compositions. Adjustable pellet size: Pellet diameter and length can be adjusted by changing the die and cutter settings to meet different animal feed requirements.
Feed Pellet Drying Machine	Dryer: 3-tier structure / 3 m Power: 21 kW Dimensions: 3.5 × 1 × 1.5 m Weight: 800 kg		Removes excess moisture from freshly extruded pellets and reduces their moisture content to a level suitable for safe storage, typically around 8%–10%, depending on the product and storage conditions.	High thermal efficiency: Hot air circulation improves heat utilization and helps reduce energy consumption and operating costs. Precise temperature control: Drying temperature and conveying speed can be adjusted according to the feed formulation and pellet characteristics, helping prevent over-drying or surface scorching. Uniform drying: Multi-layer conveying and continuous movement promote even heat distribution and consistent moisture content throughout the batch. Improved storage stability: Proper moisture control helps reduce the risk of mold growth and extends the storage life of finished feed.
Octagon Mixing Seasonings Machine	Power: 1.5kw Weight: 200kg Processing time: 5-8 min/barrel Dimensions: 4.5*0.8*1.6m Material: 304 stainless steel		Applies oil, attractants, flavoring agents, or other liquid and powdered additives evenly to the surface of the finished pellets to improve palatability and product quality.	Uniform coating: Continuous drum rotation helps distribute oil and powdered additives evenly over the pellet surface. Precise application: Liquid and powder dosing rates can be controlled according to the formulation and production requirements. Improved palatability: Surface coating can enhance aroma and flavor, helping improve feed acceptance and intake. Flexible formulation: Different coating materials can be applied according to the requirements of different animal species and feed formulas.
cooling conveyor	Length: 5m Dimensions: 5.2*0.6*0.5 m Weight: 200kg		Cools hot pellets after drying and seasoning to near-ambient temperature before screening and packaging. Proper cooling helps prevent condensation and moisture migration during storage.	Gentle and uniform cooling: Controlled airflow reduces the risk of pellet cracking caused by rapid temperature changes. Improved pellet hardness: Cooling allows the pellets to stabilize and reach their final physical strength before packaging. Reduced condensation risk: Lowering the pellet temperature before packaging helps prevent moisture accumulation inside the bags. Easy operation and maintenance: The equipment has a simple structure and is convenient to clean and maintain.
fish feed pellet bagging packing machine	Packaging System Packaging Capacity: 200-300 bags/hour Weighing Accuracy: Static: ±0.1% Dynamic: ±0.2% Power Supply: 380 V, 50 Hz ±2%, 4.5 kW Compressed Air Supply: 0.6-0.8 MPa Compressed Air Consumption: 0.2 Nm³/min Quantity: 1 unit		Automatically weighs, fills, seals, and codes the finished feed into bags for storage, transportation, or sale.	Accurate weighing: Electronic weighing systems provide precise filling and help minimize product loss.

FAQ

What is the main difference between a wet-type fish feed pellet machine and a Dry Type fish feed pellet extruder machine?

• English Answer: The core difference lies in the use of a Conditioner and a steam system. Wet extruders introduce steam and moisture to pre-condition the raw materials before they enter the screw. Compared to the dry type, the wet process significantly increases capacity (by 2-3 times), improves product cooking (gelatinization) levels, and reduces wear and tear on the screws and barrels.

Why does a wet-type floating fish food maker machine require a steam boiler?

• English Answer: The wet process relies on steam for preheating and humidification. Steam in the conditioner ensures full starch gelatinization and protein denaturation. This results in higher-quality, more palatable pellets and reduces the energy consumption of the main motor through physical lubrication during the extrusion process.

Can a wet-type floating fish feed pellet maker machine produce both floating and sinking feed?

• English Answer: Yes. By adjusting the screw speed, conditioning temperature, moisture ratio, and the compression ratio of the die, a wet extruder can precisely control the density of the pellets. Floating feed requires a high expansion rate, while sinking feed requires controlled expansion and higher density.

How does the wet process improve feed digestibility?

• English Answer: The High-Temperature Short-Time (HTST) process in wet extrusion achieves starch gelatinization levels of over 90%. This "pre-digestion" process destroys anti-nutritional factors and eliminates pathogens, allowing pets or fish to absorb nutrients more efficiently, reducing waste, and protecting water quality in aquaculture.

What are the wearing parts of a wet-type fish feed pellet extruder machine, and what is their lifespan?

• English Answer: The main wearing parts are the screws, inner barrels, and cutting blades. Their lifespan depends on the abrasiveness of the raw materials (e.g., fiber and mineral content). Typically, screws made of high-chromium alloys can last between 5,000 to 8,000 hours under normal production conditions.

How do I choose the right D-LX series wet-type floating fish food making machine for my needs?

• English Answer: Choosing a model depends primarily on your target output. For instance, if you are a medium-sized factory aiming for 1 ton per hour, the D-LX-135 is the ideal choice. For startups or laboratory use, the D-LX-65 or 70 is more economical. You should also consider your power budget and factory ceiling height.
