Twin Screw Floating Fish Feed Extruder Machine Aquatic Animal Feed Extruder

Wet Type Twin Screw Floating Sinking Aquatic Feed Fish Food Extruder Making Machine

Twin screw wet extruder machines are commonly used in the production of puffed feed. The materials are transported through conveying equipment to the conditioner, where they are tempered by high-temperature steam and enter the puffing mechanism through a chute. Under a pair of parallel meshing screw pumps, they are instantly extruded and cut into particles from a certain shape of mold holes. There are many factors that affect the expansion of materials, but they are mainly closely related to the conditioning conditions, operating conditions of the extruder, and material properties. Changing the extrusion conditions can control the sinking and floating properties of puffed feed.

The Main features of final product puffed feed:

1. Extrusion and expansion processing is a processing process that processes raw materials through high temperature, high pressure, and instant ripening, integrating transportation, crushing, extrusion, mixing, shearing, high-temperature disinfection, and molding.

2. It can process viscous, high fat, and high moisture raw materials.

3. Good water resistance. Aquatic feed particles can maintain good stability in water, and both sinking and floating feed can remain non collapsible after soaking in water for 24 hours, maintaining aquaculture water quality and reducing feed waste.

4. Higher digestibility. It improves the digestibility of substances such as starch and protein, and the strong squeezing effect can degrade some compact cellulose, keratin, etc., greatly improving the digestibility.

5. Excellent palatability. The puffed pellet product has the characteristics of porosity and uniform texture, and produces some aromatic substances, which increases the feed's attractivity, stimulates the appetite of aquatic animals, and increases feed intake.

6. Expanded the scope of raw material utilization. The twin screw expansion function processes materials containing excessive moisture, oil, or cellulose into other forms of aquatic feed, enriching feed resources.
