What Is A Dry Type fish feed pellet processing machine

A dry type floating fish feed making machine is an extrusion system used to produce floating or sinking aquatic feed pellets without an external steam boiler.

The machine uses high temperature and mechanical pressure generated inside the extrusion chamber to cook and expand feed materials into floating pellets.

Main Applications

• Floating fish feed production
• Tilapia feed processing
• Catfish feed manufacturing
• Aquarium fish feed production
• Small aquaculture feed business startup
• Farm-use fish feed pellet production

Dry Type floating  fish feed pellet making machines are especially suitable for small and medium feed production projects.

Raw Materials Used During The Dry Type fish feed making machine Test

The machine can process many common aquaculture feed ingredients.

Tested Raw Materials

• Corn flour
• Soybean meal
• Wheat bran
• Fish meal
• Rice bran
• Bone meal
• Vitamin premix

These materials are mixed evenly before entering the floating fish feed extruder machine.

Why Raw Material Testing Is Important

Different formulas directly affect:

• Floating time
• Pellet hardness
• Feed expansion ratio
• Water stability
• Production efficiency

Testing local feed formulas before shipment improves future production stability.

Dry Type Floating Fish Feed Production Process

The factory test video demonstrates the complete fish feed manufacturing workflow.

Step 1: Raw Material Crushing

Feed materials are crushed into fine powder.

Step 2: Feed Mixing

Raw materials and additives are mixed evenly.

Step 3: Extrusion Puffing

The dry type fish feed extruder cooks and shapes pellets through high temperature and pressure.

Step 4: Pellet Drying

Fresh pellets are dried to improve storage life.

Step 5: Cooling And Packaging

Finished pellets are cooled before packaging.

This compact production process is suitable for commercial and farm-use fish feed production.
