sinking fish feed pellet making machine extruder

Extruding: it is the most important step in sinking fish feed production process. The mixture is forced through a sinking fish feed machine or floating fish feed extruder where it’s cooked under pressure, heat, and moisture, then forced through a die to shape into pellets.

The test method of sinking rate is to choose one hundred of dried extruded fish feed pellets randomly and then put them in to 3.5% salt water with temperature of 20 ℃ and record the number of sinking fish feed within 30 seconds. The time of stability in the water is up to two hours or more.

Fish feed extrusion is a way to make fish food pellets that are good for fish and easy to digest. This method changes a mix of feed ingredients into dough, which then goes through a machine called an extruder.
