Jinan Large Bullfrog Feed Production Equipment Fish Feed Production Line

Bullfrog is one of the main farmed species among edible frogs worldwide. In recent years, bullfrog has become one of the important specialty aquatic products in China's aquaculture industry, loved by millions of households. The bullfrog farming industry is becoming increasingly large-scale and intensive. The demand for bullfrog feed is also growing rapidly. The bullfrog feed production line produced by Jinan Datong, after years of improvement, features stable output, variable frequency adjustment, and stable equipment operation, making it highly favored by customers.

A. Main production systems of the Datong bullfrog feed production line:

Powder mixing system—Conveying and extrusion system—Air conveying system—Multi-layer baking system—Cooling and conveying system—Oil spraying and seasoning system—Vibrating screening system—Packaging system B. Bullfrog feed production line process:

1. Material preparation: Grinder, grind the base materials of the required feed into powder or meat paste. Function: Provide raw materials suitable for extrusion in the extruder.

2. Ingredient proportioning: Manual, weigh out the various raw materials according to the formula ratio and place them together.

3. Mixing: Mixer, powder mixer, blending machine, pour the weighed raw materials into the mixer for blending and mixing.

4. Screw conveying: Screw conveyor, transport the mixed materials through the screw conveyor into the extruder feed hopper.

5. Feed extrusion: Twin-screw extruder, feed the raw materials into the twin-screw extruder through the feed hopper for extrusion and shaping, then cut into feed pellets of the required size using a rotary cutter.

6. Conveying: Air conveyor, which transports the pellet feed into the drying chamber via an air conveyor.

7. Oven: Drying oven, which removes moisture from the feed pellets through a circulating up-and-down conveyor system. The oven has a control cabinet that allows frequency conversion speed regulation to dry the feed to the desired state.

8. Oil spraying: Oil sprayer, which sprays oil or attractants onto the surface of the feed in a mist form through the oil sprayer.

9. Seasoning: High-low drum, octagonal drum, single drum, which evenly coat the seasoning onto the feed pellets through the rolling motion of the drum.

10. Cooling and conveying: Cooling conveyor, which transports the feed to the next step using a fan, reducing the feed temperature, decreasing water vapor, and extending the shelf life.

11. Vibration screening: A vibrating screen sifts particles through back-and-forth motion, ensuring uniform particle size and allowing the recovery of不合格 particles to reduce waste.

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

C. Features of the Datong Bullfrog Feed Production Line:

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

2. Simple equipment installation and layout. Based on the customer's factory and water/electricity supply, the layout can be designed. The production line can be arranged with turns, and some equipment can be placed vertically to save space for material storage.

3. The screw inside the main machine of this bullfrog feed production line is specially treated and designed to be self-cleaning, easy to use, with low wear rate and relatively low replacement frequency.

4. The main machine of this bullfrog feed production line is a multifunctional extruder. By changing different molds and related auxiliary equipment, products of different outputs and shapes can be produced. It can be adjusted according to the market, offering higher cost-effectiveness for long-term investment.

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

6. The fish feed produced by this bullfrog feed production line undergoes high-temperature puffing, changing the feed's organizational structure, making it more palatable and easier to digest, suitable for various fish, shrimp, and crabs.

7. The feed has a high effective consumption rate. The puffed fish feed is sterilized by high-temperature puffing in the extruder, with stable starch gelatinization and fat content. The puffed fish feed improves palatability and is easier to digest, with a longer shelf life.

8. Energy-saving and low pollution. This production line operates on electricity, a clean energy source with minimal pollution. It can run and produce as long as three-phase power is available.

9. The feed produced by this bullfrog feed production line can be used for: various ornamental fish such as peacock feed, parrot feed, phoenix feed, etc., and can also be used for: bullfrog feed, bullfrog feed, giant salamander feed, turtle feed, tilapia feed, grass carp feed, carp feed, bass feed, and other aquaculture feeds. It has been favored by customers for many years.
