The application staged double screw extruder and bulking machine, advantage:1. improve the production capacity 20~40% of aquatic products puffing material
Left and right.2. reducing energy consumption, current reduction 20%~30% in the case of same production capacity, saves energy consumption.3. cavity pressure is evenly, product
Stability is more preferable.4. current fluctuation smaller in production process, operation is more stable.5.)Discharging is evenly.6. product more expects that shape is more equal
It is even.7. it is more preferable to crumple effect.8. material curing degree is more preferable, it is more suitable for producing high grease, low starch(Within content of starch 10%)'s
High-grade buoyancy and sinking feed, substitute the problem of conventional helical configuration electric current is high, and material curing degree is bad, or production capacity is not high.
