Bullfrog is the main cultivated species of edible frogs in various places. In recent years, bullfrog has become one of the important famous aquatic products in aquaculture in my country. Bullfrog is the main cultivated species of edible frogs in various places. In recent years, bullfrog has become an important famous aquaculture product in China. One of the special aquatic products, loved by thousands of households, the bullfrog breeding industry is becoming more and more large-scale and intensive. The demand for bullfrog feed is also growing rapidly. After years of improvements, the bullfrog feed extrusion machinery production line produced by Jinan Datong has stable output, adjustable frequency, and stable equipment operation, and is deeply loved by customers.
A. Main production systems of Datong bullfrog feed production line:
Powder mixing system - Conveying and puffing system - Air conveying system - Multi-layer baking system - Cooling and conveying system - Oil injection seasoning system - Vibration screening system - Packaging system
B. Bullfrog feed extrusion machinery production line process:
1. Material preparation: pulverizer, pulverizes the required feed base into powder or meat paste. Function: provides raw materials suitable for puffing by the extruder.
2. Ingredients: Manually, weigh the various raw materials according to the formula proportions and put them together.
3. Mixing: mixer, powder mixer, mixer, pour various weighed raw materials into the mixer for mixing.
4. Screw conveyor: Screw conveyor transports the mixed materials into the extruder feeding hopper through a spiral.
5. Feed extrusion: twin-screw extruder, the raw materials are fed into the twin-screw extruder through the feeding hopper for puffing and molding, and then cut into feed particles of the required size by the rotary cutter.
6. Conveying: Air conveyor transports the pellet feed into the drying box through the air conveyor.
7. Oven: Multi-layer oven, which dries the moisture in the feed particles through circulating upper and lower layers. The oven has a control cabinet that can dry the feed to the required state through frequency conversion speed regulation.
8. Oil spraying: Oil spraying machine sprays oil or attractant into a mist on the feed surface through the oil spraying machine.
9. Seasoning: high and low rollers, octagonal barrels, and single rollers. Roll the flavoring back and forth through the roller to stick to the feed particles more evenly.
10. Cooling conveyor: The cooling conveyor is blown by a fan and transported to the next step, which can lower the temperature of the feed, reduce water vapor, and extend the shelf life.
11. Vibration screening: Vibration screen shakes back and forth to screen particles, which can make the particles uniform and recycle unqualified particles to reduce waste.
12. Packaging: Packaging machine, packaging by weight, the quality of feed can be improved through exquisite packaging, making it more convenient and hygienic for customers to use.
Features of bullfrog feed extrusion machinery production line:
1. Easy to learn and operate. This production line uses a frequency converter to adjust the speed. The temperature, speed adjustment, etc. can be directly seen through the control cabinet and can be adjusted through buttons.
2. The equipment is easy to install and place. According to the customer's factory building, water and electricity can be designed and placed. The production line can be placed in a curve. Some equipment can be placed vertically, which can save space for storing materials.
3. The screw in the main unit of the bullfrog feed production line has been specially designed to be self-cleaning, easy to use, has a low wear rate, and has a relatively low replacement frequency.
4. The main machine of this bullfrog feed production line is a multi-functional extruder. By replacing different molds and related supporting equipment, products with different outputs and shapes can be produced. It can be adjusted according to the market, and long-term investment is more cost-effective.
5. The size of the feed produced by this bullfrog feed production line can be large or small. The main sizes are 1mm 1.5mm 2.0mm-10.0mm, which is suitable for all kinds of young fish and large fish.
6. The fish feed produced by this bullfrog feed expansion machinery is fully expanded at high temperature, and the feed structure changes, making it more palatable and easy to digest, and is suitable for a variety of fish, shrimps and crabs.
7. The effective consumption rate of the feed is high. The puffed fish feed has been sterilized by high-temperature puffing in the puffing machine. The starch gelatinized fat content is stable. The puffed fish feed has improved palatability and is easier to digest, and has a longer shelf life.
8. Energy saving and low pollution. The production line is powered by electricity. It is a clean energy source with little pollution. Production can be run as long as there is three-phase electricity.
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. It can also be used for: bullfrog feed production line, salamander feed production line, turtle feed production line, tilapia Feed production line, grass carp feed production line, carp feed production line, bass feed production line and other aquaculture feeds have been loved by customers for many years.
