Shandong bullfrog extruded feed extrusion machinery

Bullfrog is one of the main farmed species of edible frogs in various regions. In recent years, bullfrog has become one of the important specialty aquatic products in China's aquaculture industry. It is widely favored by households, and bullfrog farming is becoming increasingly large-scale and intensive. The demand for bullfrog feed is also growing rapidly. The bullfrog feed extrusion machinery production line produced by Jinan Datong, after years of improvement, offers stable output, adjustable frequency conversion, and stable equipment operation, making it highly popular among customers.

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

Mixing system—Conveying puffing system—Air conveying system—Multi-layer baking system—Cooling conveying system—Oil spraying seasoning system—Vibrating screening system—Packaging system B. Bullfrog feed puffing machinery 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. Batching: 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: Multi-layer oven that dries the moisture in feed pellets through circulating upper and lower conveyor belts. The oven has a control cabinet that can adjust the frequency 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.

D. Characteristics of bullfrog feed extrusion machinery 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. The equipment is easy to install and arrange. According to the customer's factory layout, water and electricity can be designed for placement. The production line can be arranged with turns, and some equipment can be placed vertically, saving space for material storage.

3. The screw inside the main unit of this bullfrog feed production line is specially treated and designed to be self-cleaning, convenient 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, with main sizes ranging from 1mm, 1.5mm, 2.0mm to 10.0mm, suitable for various young and adult fish.

6. The fish feed produced by this bullfrog feed extrusion machinery undergoes high-temperature full expansion, changing the feed's organizational structure, making it more palatable and easily digestible, suitable for many types of 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 production line, parrot feed production line, phoenix feed production line, etc., and can also be used for: bullfrog feed production line, giant salamander feed production line, turtle feed production line, tilapia feed production line, grass carp feed production line, carp feed production line, perch feed production line, and other aquaculture feeds. It has been favored by customers for many years. Fish feed production line.
