If aperture ratio is big, discharge flow would be bigger. Whether an object floats or sinks depends on its density. The stuff from which they are made is not so densely packed. Similarly, the pressure at the bottom of an object submerged in a fluid is greater than at the top of the object. Play our cool KS1 and KS2 games to help you with Maths, English and more. Wet type fish feed machine is more suitable for large scale production and people who have higher requirements for feed pellet performance.

The picture … Oil spraying step is optional. For acquiring better smell and taste, people often use oil spraying machine to spray oil to the surface of fish feed pellets. For feed production, dry type fish feed extruder is recommended, due to suitable price and stable performance. Characterization of the gastrointestinal transit and disintegration behavior of floating and sinking acid-resistant capsules using a novel MRI labeling technique. Fish feed extruder is the main manufacturing equipment for extruding and sinking fish feed. Floating fish feed has a higher feed efficiency. But before I start, I would like to make a statement that neither can be considered superior compared to the other and your choice of whether to use floating or sinking pellets mainly depends on which type of fish species that you have. Floating fish feed will not dissolve in water for a long time, and high-quality floating fish feed can enjoy up to 12-hour floating time.
