Process flow of Datong fish feed production equipment

Main process introduction of the fish feed production equipment, floating fish feed production line, and fish feed extrusion machinery configured by Datong:

1. Material preparation: The main machine is a grinder, which grinds bones, minced meat, etc. into a bone paste state. Function: Provide raw materials suitable for extrusion by the extruder.

2. Ingredients: Weigh and prepare various raw materials for feed production according to the formula ratio. Function: The formula determines whether the fish will like the feed, making this step crucial.

3. Mixing: Mixing machine, blender. Place the prepared feed into the mixer for thorough stirring and blending. Function: Fully and evenly mix multiple raw materials. 4. Screw Conveying: Screw conveyor. Transport the mixed feed into the extruder's feeding hopper via screw conveying. Function: Screw conveying reduces waste during transport and adjusts the conveying speed according to production output.

5. Twin-Screw Feed Extrusion: Twin-screw extruder. The feeding hopper delivers raw materials to the extruder according to production output for extrusion and pelletizing. Function: After high-temperature and high-pressure extrusion, the product's particle structure changes, making it more suitable for fish digestion and absorption.

6. Air conveying: The air conveyor transports granular materials into the drying equipment using air speed. Function: Reduces manual material lifting costs and ensures cleanliness and hygiene.

7. Oven: A multi-layer oven that uses a reciprocating mesh belt to transport and dry granular materials to control moisture content. Function: Quickly dries the feed to extend its shelf life.

8. Oil spraying: The oil sprayer sprays oil or attractants onto the materials. Function: Uses the sprayer to atomize the sprayed substances into a mist for more even application.

9. Seasoning: High-low drums, single drums, and octagonal drums add seasonings and various additives to granular materials through rolling motion. Function: The rolling action of the high-low drums ensures more even seasoning of the feed.

10. Cooling Conveying: Cooling conveyor, transports to the next step via fan blowing, function: reduces the surface temperature of the feed.

11. Vibrating Screening: Vibrating screen, screens particles through shaking, function: makes particles uniform, recovers small particles to reduce waste.

12. Packaging: Packaging machine, performs weight-based packaging, function: enhances the grade of the feed through attractive packaging, making it more convenient and hygienic for customers.
