Pelleting Quality & Nutrition Control

Low-velocity conveying reduces pellet breakage and fines during transfer.

Vacuum coating improves oil distribution and reduces surface leakage risk.

Inline moisture monitoring helps control thermal impact on heat-sensitive nutrients.

Multi-zone temperature control ensures uniform pellet expansion and structural density.

Variable dryer speeds optimize residual moisture distribution to ensure long-term storage stability.

Factory Capabilities & Quality Control

Laser Particle Testing: Grinding output reaches about 80 mesh with ~95% pass rate under test conditions

Ultrasonic Flaw Detection: Main shaft welds undergo 100% scanning to prevent structural cracks under stress.

Dynamic Balance Calibration: Rotor vibration is controlled under 2.8 mm/s during operation.

Hardness Depth Gauging: Screw elements reach HRC 58-62 hardness to deliver extended operational wear life.

Moisture Variance Checks: Automated drying keeps final pellet moisture gaps below 0.5% for safe storage.

FAQ

Q: Can this setup switch between processing floating and sinking aquatic pellets without changing the screw?

A: Yes, density is adjusted through formula changes, cutter speed, and barrel temperature control.

Q: What is the typical lead time for replacement dies and screw segments when ordering spares?

A: Standard wear parts usually ship within 5–7 working days from stock.

Q: How does the system handle high-oil formulations without causing product slippage inside the barrel?

A: We use multi-groove barrel liners and segmented screw designs to maintain stable material feeding.
