Floating fish feed extruder

The floating fish feed extruder is a floating feed production line that can be used from fry to adult fish. Based on stable production and guaranteed equipment quality, from bone paste to packaging, this floating fish feed production line has been developed according to market demand and years of technical experience. The fish feed produced by this equipment is easy to digest, has high absorption rate, and reduces waste by allowing the feed to float on the water surface. It is suitable for feed production with high protein content. The feeding equipment is divided into wet and dry fish feed production equipment.

I. Process flow of floating fish feed production equipment:

1. Preparation: The main machine is a grinder, which processes bones and other minced meat into a paste state. Function: Provides suitable raw materials for the extruder expansion.

2. Ingredients: According to the formula ratio, weigh and proportion the raw materials for feed production. Function: The formula is related to whether the fish likes it, which is very important.

3. Mixing: Put the prepared feed into the mixer for thorough mixing and blending.

4. Screw Conveying: The mixed feed is conveyed into the feeder of the expander through a screw conveyor. Function: Screw conveying reduces waste during transportation and adjusts the conveying speed according to the output.

5. Twin-Screw Extruder Feeding: The yield from the feeder to the extruder is used to convey materials for extrusion and granulation. Action: The change in high-pressure extrusion makes the product particles more suitable for fish digestion and absorption in terms of tissue structure.

6. Pneumatic conveying: Granular materials are transported to the drying equipment by wind speed. Function: Reduces manual feeding costs and maintains cleanliness and hygiene. Floating fish feed production line 7. Oven: Uses a circular reciprocating mesh belt to dry the moisture of the granules. Effect: Quickly dries the feed to extend its shelf life.

8. Oil spraying: Enters the oil sprayer or food inducer. Effect: The sprayed substance passes through the oil sprayer in mist form, making it more uniform.

9. Seasoning: Rolls back and forth by adding seasonings and various additives to the granular material. Function: The horizontal back-and-forth rolling of the drum ensures more even seasoning of the feed.

10. Cooling and conveying: Sent to the next step by a fan, its function is to reduce the surface temperature of the feed.

11. Vibration screening: The vibrating screen filters particles through vibration, function: to make particles uniform, small ones can be recycled, reducing waste.

12. Packaging: Weight packaging, function: through exquisite packaging, the grade of feed can be improved, making it more convenient and hygienic for customers to use.
