Shandong large-scale wet extrusion fish feed equipment production line

The main equipment of the large-scale wet fish feed production line produced by Jinan Datong Machinery Equipment Co., Ltd. includes:

Bone paste/crusher → powder mixer → screw feeder → twin-screw feed extruder → conveyor → multi-layer drying equipment → air conveyor → oil sprayer → seasoning line → cooling conveyor → vibrating screen → packaging machine. I. Features of the large-scale wet fish feed production line:

1. Prevents feed waste. Extruded fish feed has good stability in water and generally does not dissolve within a certain period, effectively preventing the feed from dispersing and settling in the water, thereby reducing feed waste to a certain extent.

2. Reducing water pollution, extruded fish feed can float on the water surface, is not easy to sink or dissolve, and leftover feed can be scooped up, dried, and used for the next feeding, thus effectively preventing feed from deteriorating in the water and reducing water quality pollution.

3. High effective feed utilization rate, extruded fish feed undergoes high-temperature extrusion sterilization, with stable starch gelatinization and fat content. The extruded feed improves palatability and is easier to digest, with a longer shelf life.

4. Energy-saving and low pollution, this production line operates on electricity, producing minimal pollution. It only requires a three-phase power supply to run.

5. Easy to learn and operate, this production line uses a frequency converter to adjust speed. The control panel allows direct viewing of temperature and speed adjustments, which can be made via buttons.

6. The equipment is easy to install and arrange. Depending on the customer's factory layout, water and electricity can be designed accordingly. The production line can be arranged in curves, and some equipment can be placed vertically, saving space for material storage.

7. The screw inside the main unit of the production line is specially treated and designed to be self-cleaning, making it convenient to use. It also has low wear and tear, requiring relatively infrequent replacement.

8. The main unit of the production line is a multifunctional extruder. By changing different molds and related auxiliary equipment, it can produce products of various outputs and shapes. It can be adjusted according to market demands, offering higher long-term investment cost-effectiveness.

9. The feed produced by this production line can be of various sizes, mainly including 1mm, 1.5mm, 2.0mm to 10.0mm, suitable for various juvenile and adult fish.

10. The feed produced by this production line can be used for: various ornamental fish such as peacock feed, parrot feed, phoenix feed, etc., as well as for aquatic farming including bullfrog feed, crayfish feed, giant salamander feed, turtle feed, tilapia feed, grass carp feed, carp feed, bass feed, etc. It has been favored by customers for many years.

2. Wet fish feed production equipment process flow:

1. Material preparation: The main machine is a grinder, which grinds bones, minced meat, etc., into a bone paste state. Function: Provides raw materials suitable for extrusion in 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: Place the prepared feed into a mixer for thorough stirring and blending. Function: Ensure even mixing of multiple raw materials. 4. Screw Conveying: Transport the mixed feed via a screw conveyor into the extruder's feed hopper. Function: Screw conveying reduces waste during transport and adjusts the conveying speed based on production output.

5. Twin-Screw Feed Extrusion: The feed hopper delivers raw materials to the extruder based on production output for extrusion and pelletizing. Function: The product pellets undergo structural changes after high-temperature and high-pressure extrusion, making them more suitable for fish digestion and absorption.

6. 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: Uses a reciprocating mesh belt to transport and dry granular materials to control moisture content. Function: Quickly dries the feed to extend shelf life.

8. Oil spraying: Enters the oil sprayer to spray oil or attractants. Function: Uses the sprayer to atomize the sprayed substance into a mist for more even application.

9. Seasoning: Adds seasonings and various additives to the granular materials through rolling. Function: Uses high and low drums to roll back and forth, ensuring more even seasoning of the feed.

10. Cooling conveyor: Transports to the next step using fan blowing. Function: Reduces the surface temperature of the feed.

11. Vibration screening: The vibrating screen sifts particles through shaking, function: to make particles uniform and recover small particles to reduce waste.

12. Packaging: Weight-based packaging, function: to enhance the grade of feed through exquisite packaging, making it more convenient and hygienic for customers.
