company news about 320kg per Hour Dry Type Shrimp Feed Extruder Machine Test Video

Testing a 320kg/h Dry Type sinking shrimp feed pellet extruder focuses on two critical KPIs: High Density (Sinking) and Water Stability (2+ hours). Unlike fish feed, shrimp feed must not puff. This testing protocol ensures the machine achieves starch gelatinization via friction heat without creating a floating structure, providing a cost-effective solution for small-to-medium shrimp farms.

1. The Challenge: Why Dry Extrusion for Shrimp Feed?

Shrimp are bottom feeders with slow eating habits. This creates a technical challenge for Dry Type shrimp feed pellet machines:

• The Problem: Friction heat in dry extruders naturally causes "puffing" (expansion), making pellets float.

• The Solution: Our 320kg/h machine uses a high-compression screw design and precise moisture control (18-22%) to ensure pellets are dense, heavy, and sink immediately.

• Cost Advantage: Eliminating the steam boiler reduces the initial investment by 40%, making it ideal for startups in regions where boiler certifications are difficult to obtain.

2. Technical Testing Benchmarks (Industrial Standards)

During the pre-shipment test video, we monitor these specific metrics to ensure the shrimp feed meets commercial standards:

3. Key Phases of the 320kg/h Shrimp Feed Test

Phase 1: High-Density Die Testing

Shrimp feed dies are thinner than fish feed dies to increase pressure. We test the flow rate to ensure that even at a 1.0mm diameter, the machine maintains a 300kg/h+ output without clogging.

Phase 2: Starch Gelatinization & Binding

Shrimp feed requires a high "cook" to stay together underwater.

• Expert Note: During the test, we add a small amount of wheat gluten or specialized binders. The twin-screw (or high-shear single screw) must mix these thoroughly using only mechanical heat to ensure the pellet stays firm in water for 2-4 hours.

Phase 3: The "Glass Jar" Stability Test

In the video, we take fresh pellets and drop them into a jar of water.

• Success Criteria: The pellets must sink instantly. After 60 minutes, the water should remain clear (no nutrient leaching), and the pellet should remain whole when touched.

4. Solving Pain Points: Shrimp Feed Troubleshooting

• Pain Point: Pellets are floating or slow-sinking.

  • Solution: Increase the moisture content in the mixer or reduce the screw speed. This lowers the friction-induced "puffing" and increases pellet density.

• Pain Point: High "Fines" (Dust) in the bag.

  • Solution: Check the raw material grinding. For shrimp feed, if the ingredients are too coarse (above 60 mesh), the "skin" of the pellet will be rough and crumble easily.

• Pain Point: Machine overheating.

  • Solution: For dry extruders, we test the water-cooling jacket around the barrel to ensure the temperature stays below the "puffing threshold."

5. FAQ: 

Q: Can a small shrimp feed pellet extruder machine really produce feed that stays stable for 4 hours?
A: Yes, but it requires the right formula. You must use a high-protein recipe with at least 20% wheat flour or starch and grind materials to 80-100 mesh. The dry extruder’s high-pressure zone acts as a "pressure cooker" to bind these ingredients tightly.

Q: Why does my shrimp feed make the pond water cloudy?
A: This is due to poor water stability. It means the starch wasn't fully gelatinized during extrusion. Our test ensures the 320kg/h machine reaches the correct "cooking" temperature to lock the nutrients inside the pellet.

Q: What is the smallest pellet size this sinking shrimp feed pellet making machine can produce?
A: Our 320kg/h model is optimized for 1.0mm to 3.0mm pellets. For sizes smaller than 1.0mm (crumbled feed), additional equipment like a pellet crumbler is recommended after the extrusion process.

Q: How much water should I add to the mixer for dry shrimp feed?
A: Typically, 15% to 20% total moisture. If you go below 15%, the sinking shrimp food pellet making machine generates too much heat and the pellets might puff/float. If you go above 22%, the pellets may become too soft to cut cleanly.

Q: Is dry type extrusion suitable for commercial shrimp farming?
A: It is excellent for intensive small-scale farming and local feed supply. While large industrial mills use wet-type systems for 5+ ton/hour capacities, the 320kg/h dry type is the most profitable entry point for private farms due to its low maintenance.
