1. Automatic control direct cooling wet extruder,specialized for production of ornamental fish, pets and aquatic extruded feed.
2. Use double thread varying pitch screw with good effect of hearing and kneading,wide range of processing pellet (1.0mm-16mm round and abnormal float feed, sinkable Feed）, big extrusion pressure,quick conditioning and curing, good effect of molding.
3. In technology, use screw thread direct cooling,sliced kneading ring,inner evaporation conditioning and main shaft with variable frequency stepless adjustable speed,combining with formula to process aquatic sinkable feed and float feed.
4. Due to special structure, in the same condition,fat addition content of feed production or processing is higher than other single srew models.This model can be used some materials (as corn flour and soybean flour) dry extrusion.
