JB/T 11687-2026Single-screw extruder for aquafeed (English PDF)

JB/T 11687-2026 is the English-translated version of 单螺杆水产饲料膨化机.

JB/T 11687-2026 applies to the single-screw extruder for aquafeed, a machine in which one screw conveys, works and puffs feed material for aquatic animals. The document treats this machine as a product of the feed machinery industry and is the single-screw counterpart of the standard for twin-screw machines.

Aquafeed plants that purchase extruders, the manufacturers who build them and the laboratories or inspectors who evaluate them will find it relevant. It is voluntary, as the /T in its code indicates. The Ministry of Industry and Information Technology issued it on 1 June 2026, and it comes into effect on 1 December 2026. It replaces JB/T 11687-2013.
