What is the difference between the feeds produced by different processes of feed expanding machine?

                Expanded sinking feed and slow sinking feed and expanded floating feed production process has a similarity, all through the modulator heating modulation, into the extruder after the depth of the feed material kneading treatment, and then reach the pelleting end of the puffing shape. However, due to the expanded sinking feed, expanded slow sinking feed and expanded floating feed specific gravity requirements are not the same, so there are differences in the feed production process requirements.

                Expanded sinking feed and slow sinking feed require higher specific gravity of the feed, so the feed is required to have a better tightness and smaller degree of expansion, in order to achieve such process requirements, different measures can be taken. The interaction of screw speed and feed rate, feed rate and its secondary term and feed rate have a very significant effect on the degree of expansion, while theoretically there is a negative correlation between degree of expansion and density.
