DSP Wet Type Floating Fish Feed Machine

1. Operating parts adopt the humanization design which makes the machine easy to operate.
2. Sizes of the feed pellets can be adjusted according to the customer's requirement by changing different molds.
3. Salmonellosis and bacterial infections can be killed during the high temperature and high pressure pelletizing process, which can also make pellets easy to digest and absorb.
4. Floating pellets made by this wet-type fish feed extruder have high quality which can float on the water for more than 12 hours.
5. Raw materials can be fully cooked as the boiler provides hot steam into the conditioner continuously, so the nutritional value of the feed pellets can be improved.
6. Key parts have a long service life as they are processed through vacuum quench treatment with high processing precision.
7. It is widely used in Fish Feed Pellet Mill Plant, Crab Feed Pellet Plant Production Line, Shrimp Feed Pellet Making Plant, etc

Raw Materials

The material selection is very wide, such as soybean meal, corn flour, wheat meal, bone meal, meat meal, fish meal and so on. Here is the material requirement:

• Material moisture: 20%-25%
• Material type: powder
• Material fineness: 60 mesh – 80mesh

Working Principle

The heart of the extruder machine working is: preconditioning, cooking, and die shaping. With the boiler continuously providing hot steam into the conditioner, mixed materials from the fish feed mixer can be fully cooked and the nutritional value is improved. The cooking process can cause a high level of gelatinization of starches, results in feeds with good water stability. The fish feed extruder is a long barrel with a screw auger inside which is specially designed to subject feed mixtures to high heat and steam pressure. When feed exits the die at the end of the barrel, trapped steam blows off rapidly, the soft warm pellets expand, and a low density floating pellet is produced. After that, a cutting device will cut the formed pellets into different lengths as required. The extruder is very versatile and can make feeds with many different characteristics.

Attentions: our fish feed extruder is of a single screw design. The pellets extruded from the pellet mill are about 80℃ and moisture content is 18%-20%, so you should equip a dryer and cooler if the capacity is more than 500kg/h. While for small capacity, you can dry them in the sun. We also provide technical formulas for making floating fish feed pellets after placing an order.

The Benefits of Puffed Fish Feed Pellets

1. From the fish feed extruder, feed pellets are in a 'popcorn' state, not only the physical state has been changed, but also the shape and internal structure of organic molecules have been changed, which makes feed pellets easier to digest and absorb for fish.
2. After treatment of puffing, the fragrance, and palatability of the feed have been improved to stimulate the appetite of the animal.
3. High temperature and the high-pressure process can kill salmonellosis and bacterial infections and makes the pellets Hygeian for fish.
4. The puffed fish feed pellets can float on the water surface without dissolution for over 12 hours, reduce feed waste and keep the water quality.

Application

• Make high-grade aquatic feed pellets for fish, catfish, shrimps, crab etc.
• Ideal for making pet food for dogs, cats, etc.
• If you have fish ponds and aquatic farms, this machine is really cost-effective compared with buying expensive pellets.
• First choice of fish feed pellets manufacturers.
