Detailed Process Overview:

✅Preconditioning and Mixing:

• Raw materials such as grains, proteins (e.g., fish meal, soybean meal), and micronutrients are finely ground and thoroughly mixed to form a uniform feed base.

• The mixture is then pre-conditioned using steam or hot water to raise the moisture content and soften ingredients, aiding in starch gelatinization for better binding and digestibility.

✅Extrusion:

• The pre-conditioned mix is fed into a cylindrical barrel with a rotating screw (auger).

• As the material is pushed forward, temperature and pressure increase due to mechanical shear and friction.

• This process “cooks” the feed—gelatinizing starches and denaturing proteins—enhancing nutritional availability and digestibility.

✅Shaping and Cooling:

• The cooked mixture is extruded through a die plate at the end of the barrel, forming it into uniform pellets.

• Upon exiting, the sudden drop in pressure allows steam to escape, causing the pellets to puff and expand.

• Pellets are then cut to size, cooled, and prepared for packaging.

Types of Extrusion:

🔹Dry Extrusion

• Relies on frictional heat, requiring minimal water.

• Produces low-moisture, durable pellets—ideal for extended shelf life.

🔹Wet Extrusion

• Uses steam or hot water during preconditioning.

• Creates a greater expansion effect with improved palatability.

✅ Benefits of Using a Fish Feed Extrusion Machine by Premient Engitech PVT LTD:

🔹Improved Digestibility: The thermal treatment makes nutrients more bioavailable for fish.
🔹Enhanced Palatability: Produces feed with better flavor and texture, increasing consumption rates.
🔹Sterilization: High heat eliminates pathogens, making feed safer for aquatic livestock.
🔹Versatile Pellet Production: Capable of creating floating, semi-floating, and sinking pellets for various species.
🔹Efficient Storage & Transport: Low-moisture pellets reduce storage costs and spoilage risks.

Whether you’re feeding shrimp, catfish, tilapia, ornamental fish, or carnivorous species, the Fish Feed Extrusion Machine for Fish Feed from Premient Engitech PVT LTD delivers consistent performance and pellet quality that meet the high standards of modern aquaculture.
