Aquatic Feed
  • Total Control of Pellet Attributes

    Unique extruder features allow precise control of finished product density for floating and sinking feeds. The operator can also adjust operating conditions to control textural properties, such as oil uptake during the external coating process.

  • Superior Production Efficiency and Versatility

    • Produce aquatic feeds ranging in pellet size from 0.5 to 50 mm

    • Allow up to 22% fat or fish oil to be incorporated during extrusion

    • Permit the use of a wider range of raw materials through optimization of energy sources

  • Greater Feed Stability in Water

    Durability of feeds for bottom dwellers has shown stability of 24 hours or longer without the inclusion of binders. Floating feeds also exhibit superior durability and floating qualities.

AquaFLEX™ - Produce High Quality Feeds in High Volumes - including Micro Feeds

AquaFLEX is the industry's most flexible extrusion system for aquatic feed, enabling production of floating, slow sinking, and sinking products using a wide range of ingredients and recipies. Using twin screw technology, this innovative extruder excels at producing a highly uniform product with excellent nutrition retention and water stability.

Shrimp Feed Dryer The Wenger Four Pass Continuous 24x30 Shrimp Feed Dryer

Shrimp Feed Dryer


  • The Mesh Screen Conveyor retains all feed while maximizing process airflow that removes moisture from the product.
  • Heavy Duty Steam Coils ensure reliability and provide an abundance of consistent, efficient heat to the drying process.
  • The new Direct Drive Spout Spreader provides easy in-line adjustment of spreader to create a level product bed, which is important for uniformity in the final product moisture level.​DOWNLOAD BROCHURE 

Efficient Use of Plant Space

The Shrimp Feed Dryer uses height instead of taking up limited floor space in the plant. Product goes through extra passes within the taller framework of the dryer, which means it’s blended multiple times during the continuous drying process.

Retention Time

Variable speed control of all conveyors in the Shrimp Feed Dryer provides process adjustment to pinpoint the drying time and bed depths needed for the shrimp feed drying process.

Temperature Control

Using its heavy-duty steam coils, the Shrimp Feed Dryer’s steam control valves precisely control zone process temperature. Three temperature zones provide flexibility for perfecting the process parameters.

Airflow Control

Fine-tuning of process airflow speed and balance allows for production of a variety of feed sizes and densities while maximizing drying capacities of each product.

  • Airflow from both sides of the dryer provides even drying across the bed
  • Speed control optimizes the drying capacity of each product
  • Available adjustments improve efficiency of the drying process and quality of the final shrimp feed
