With pin each section machine barrel and barrel jacket are fixed up, again the order of each section by pan feeding section, feeding section, centre portion, expanded section, discharging section is connected in series, with main shaft in the middle of each section screw rod or channel bar, one end of main shaft (being generally the end by the pan feeding section) is established a main spindle box, and the main shaft end is fixedly connected discharging spline channel bar with screw.

Be installed in belt pulley on the main shaft with driven by motor during work, make the main shaft high speed rotating, feeding section screw rod in the Builking cavity machine barrel, stirring gelatinization section screw rod, combined threaded rod, expanded section screw rod and pull-off section channel bar runs up simultaneously, material is sent into from charging aperture, and material passes through in Builking cavity:

The pan feeding screw rod of feeding section and feeding spiro rod stir material and send into centre portion, and material forms expanded at the beginning material simultaneously under the effect of water and steam;

After material enters centre portion, under the effect of steam and combined threaded rod modified evenly, after be pressed into expanded section;

Material is realized expanding treatment at the expanded section of spline machine barrel;

Expanded material is after discharging spline channel bar section makes expanded good feed release Builking cavity.

The utility model concentrates on feeding, modified gelatinization, function such as expanded to realize in the Builking cavity, shortened the time of expanded material greatly, the material expansion rate reaches more than 99%, and swimming property of expanded pellet diet is good, quality is high, the power consumption end, nutritive loss is few, increase palatability, favourable digesting and assimilating.
