Size Differences Between Feed Pellets

The preference of good-looking products on the fiercely competing market have had feed machinery manufactures pay more attentions to the appearance quality of extruded feed pellets.

Muyang therefore in here offers some operational tips to help eliminate appearance problems and add value to feed extrusion productions, with the support of our experienced service technicians. The most common problems on the appearance of extruded feed are size difference, irregular shape, and poor pellet surface smoothness.

Size difference

Size differences between feed pellets are inevitable in extrusion productions. An acceptable range therefore is defined to identify whether a pellet is qualified in size or not. Pellets that size in the range are “uniform” and qualified, while out of the range are nonconforming products and should not be delivered to customers.

For example, feed pellets that extruded out from 3.0mm die openings if ranging from 4.2mm to 5.0mm are acceptable, while of 3.5mm or φ6.0mm diameter is unacceptable. Therefore, to control extrusion process and prevent nonuniform finished pellets from production is very important.
