The core technology and application characteristics of aquaculture fish feed production line equipment can be summarized as follows:
I. Equipment composition module
Raw material processing system
Raw material screening and cleaning equipment: used to remove metal impurities, rope ends and other foreign matter to ensure the safety of raw materials.
Crushing equipment: including water drop type grinder and ultrafine grinder to meet different fineness requirements and improve raw material utilization.
Mixing equipment: using a double-shaft paddle mixer to achieve uniform ratio of multiple raw materials and high mixing uniformity.
| Model | Capacity | Dimension | Weight |
| DGP40 | 0.04-0.05T/H | 1400*1030*1200MM | 240KG |
| DGP50 | 0.06-0.08T/H | 1400*1030*1200MM | 320KG |
| DGP60 | 0.12-0.15T/H | 1450*950*1430MM | 480KG |
Granulation module
Extrusion extruder: core equipment, supporting floating/sinking feed production, the single-machine capacity of the twin-screw extruder can reach 4 tons/hour.
Ring die pelletizer: suitable for high-density pellet molding, the pellet specifications are adjusted by the mold to adapt to the needs of different fish species.
Steam conditioning system: improve starch gelatinization through temperature control, improve feed palatability and digestibility.
Post-processing system
Cooling and drying module: use countercurrent cooler to reduce pellet temperature, and use drying equipment to control moisture to safety standards.
Functional enhancement equipment: optional grease sprayer, sieving machine and automatic packaging machine to improve product stability and packaging efficiency.
