Equipment Specifications
Introduction to the Process Flow
1. Raw Material Intake System: Customizable to requirements; supports delivery via truck, unloading from bulk bags, or manual feeding.
2. Batching System: Customizable based on raw material characteristics and formula requirements; features precise PLC control, eliminating the need for manual on-site operation.
3. Mixing System: Designed for dry materials; ensures high uniformity (variation <5%) and excellent sealing to prevent leakage. Features a large bottom-opening discharge gate for rapid, residue-free unloading.
4. Pulverizing System: Utilizes an ultra-fine pulverizer suitable for processing shrimp feed, small-particle extruded feed, various aquatic feeds, and pet food ingredients. Employs an innovative screenless design with air classification and a unique grinding disc configuration to achieve high output and efficiency. Produces uniform, stable particle sizes while maintaining low material temperatures during processing, effectively preserving raw material quality.
5. Extrusion System: A twin-screw extruder that uses screw rotation and compression to subject raw materials to shearing, mixing, and cooking under high-temperature, high-pressure conditions. Precision shaping via specialized dies allows for controlled product specifications and forms. Equipped with a high-speed, high-torque gearbox, the system offers high load-bearing capacity, low noise, and superior processing efficiency, meeting the demands of large-scale feed production.
6. Drying System: Features a high-efficiency circulating dryer utilizing advanced bidirectional cross-flow hot air technology to effectively handle the drying and curing of extruded products. An internal hot-air circulation system ensures low energy consumption and reduced production costs. Flexible heating options—including steam, gas, and electric—accommodate various production requirements.
7. Coating System: Optional vacuum coating system available; allows for the incorporation of higher levels of fats and flavorings (up to 35% coating ratio), enhancing product palatability and nutritional value.
8. Cooling System: Cools material to near-ambient temperatures, effectively extending product shelf life.
9. Packaging System: Customizable to requirements.
What can a sinking fish feed production line do?
