1. Core Advantages

  • Excellent Floating Properties and Water Resistance:

Utilizing advanced conditioning, maturation, and expansion processes, this system ensures that fish feed pellets remain stably suspended in water for hours, significantly reducing fish feed waste.

  • Higher Digestibility and Absorption:

The precisely controlled maturation process fully gelatinizes starch, making protein more digestible, significantly improving nutrient absorption and utilization for the "four major carps," contributing to their healthy and rapid growth.

  • Highly Automated and Intelligent:

The entire line is equipped with an advanced PLC central control system, automating the entire process from raw material crushing, mixing, conditioning, and expansion to drying, cooling, spraying, and packaging.

  • Flexible formulations and production capacity adaptability:

The process can be flexibly adjusted to meet the specific nutritional needs of grass carp, black carp, silver carp, and bighead carp at different growth stages, producing high-quality floating fish feed in a variety of particle sizes. Flexible production capacity configuration meets the diverse needs of feed mills from small to large.
