Fish Food Feed Extruder Machine

 

 

Extruded aquatic feed uses the extruding and shearing effect of the screw and screw sleeve in the extruder to heat up and pressurize the material, and extrude the high-temperature and high-pressure material out of the die hole to reduce the pressure and complete the volume expansion. craft.
Extrusion can be divided into two processing methods: dry and wet. The dry method does not need to add water to the raw materials. The raw materials are not subjected to tempering treatment before entering the extruder barrel. , the shear plate and the inner wall of the puffing chamber play a role.
The structure of the wet extruder is more complicated than that of the dry extruder. The raw materials are tempered before entering the extruder barrel to further reach the degree of ripening. device to assist in heating or cooling.

 

The raw material formula of floating fish feed may vary depending on the expected fish species and nutritional requirements, we can provide high-quality fish feed formula after confirming the order.

 

1. Typical raw materials used in fish feed processing include grain meal, meat meal, bone meal, fresh meat and minerals and vitamins, etc.

2. After the dry material enters the pre-conditioner, it is precured with steam. Ensure proper mixing of steam, moisture and ingredients by adjusting the angle of the paddles.

1. High production capacity: Twin-screw extruders can produce a large amount of fish feed in a short amount of time. This is because they have a high extrusion rate and can process a wide range of ingredients.

2. Consistent quality: With a twin-screw extruder, you can produce fish feed with consistent quality. This is because the extruder provides a homogenous mix of ingredients and ensures that all the particles are of the same size.

3. Improved nutrient digestibility: Due to the high shear forces and temperatures in the extruder, the feed is cooked and gelatinized, making it more easily digestible for the fish.

 

1. The performance and temperature parameter setting of the extruder.
The higher the temperature, the easier it is for fish feed to expand. So when making floating fish feed, the temperature setting of the extruder will be relatively high. 

2. Raw materials
*Some in the formula: protein, fiber, oil (such as fish meal, bone meal, etc.)
This kind of raw material is not easy to expand, so when the percentage of such raw material in the formula is higher, the fish feed will easily sink.
* Starches (corn flour, wheat flour, rice flour, etc.)
Starchy ingredients are prone to puffing, so the higher the percentage of these ingredients in the formula, the easier the fish feed will be to float.

3. Moisture
The more moisture, the harder it is to expand, and the less moisture, the easier it is to expand. This is also an important factor when mixing raw materials, and extruders to produce feed.

1. Long shelf life of feed
Aquatic extruded feed has low moisture content, hard granules, reduced granule pulverization rate, and most of the microorganisms and fungus are killed during the extruding process, so it has a long shelf life and is convenient for storage and transportation. .
2. Avoid waste of feed
The aquatic extruded feed has good stability in water, and generally does not dissolve within 2 hours (some as long as more than 10 hours), so it can prevent the nutrients in the feed from dissolving and losing in the water and the feed sinking into the mud, and the residual bait is also Simply pick up and dry in the sun, which can avoid waste of feed to the utmost extent. According to experiments, the general selection of aquatic extruded feed can save about 10% of feed compared with powdered or hard pellet feed.
3. Reduce water pollution
Aquatic extruded feed does not dissolve or sink in water, so it can avoid residual fermentation of feed in water, and effectively reduce water pollution.
4. Easy to handle farming
Aquatic extruded feed can be suspended on the water surface for a long time, and there is no need to set up a special feeding platform when feeding, just fixed-point feeding is enough. Fish need to come out of the water when feeding, and can directly observe the feeding status of the fish, adjust the feeding amount in time, and know the growth status and health status of the fish in time, so the selection of aquatic extruded feed is helpful for scientific breeding management. It not only saves a lot of time, but also improves labor productivity.
