Fish feed machines are the suitable equipments for fish feed production, which can produce nutrient feeds featured with floating or sinking. There are two types of fish feed machines: dry type and wet type.

There is no basic difference between the “dry” and the “wet” extrusion, except that more shears occur in dry extruders to creat heat.

What are the pros and cons of wet extrusion compared to dry extrusion?
Wet extruders have a higher capital investment costs than dry extruders, but usually have lower operating costs. Wet extruders have higher capacities than dry extruders owing to the large drive motor requirements per unit throughput of dry extruders. Wet extruders yield superior shaped products compared to dry extruders, owing to greater processing control.
