DSP Fish Feed Extruder Machine

DSP Fish Feed Extruder Machine Introduction
DSP wet-type floating fish feed machine is mainly used to produce all kinds of floating or
sinking aqua feed for fish, shrimp, eel, bullfrog, etc. It can also be adapted to produce
feed pellets for a pet, such as a dog, cat, and so on. Raw materials for this machine can be
corn, soybean meal, rice barn, fish meal, rice barn, etc. Sizes of final feed pellets range
from 0.9 to 15mm. Wet-type fish feed pellet machine is mainly used in medium or large-size
feed pellet plants and aquaculture farms. Using this wet type fish feed pelletizer machine
production expanded feed particles, forming neat and smooth, floating over 12 hours don't
sink water, polluting the water, sterilization to reduce fish disease.

DSP Fish Feed Extruder Machine Product Advantages
1. The operating parts adopt the humanized design, which makes the machine easy to operate.

2. The size of the feed pellets can be adjusted according to the requirements of customers
by changing different molds.

3. During the high-temperature and high-pressure granulation process, salmonella and
bacterial infection can be killed, and the granules can be easily digested and absorbed.

4. The floating pellets made by this wet fish feed extruder are of high quality and can
float on the water surface for more than 12 hours.

5. The boiler continuously provides hot steam to the conditioner to fully mature the raw
materials and improve the nutritional value of pellet feed.

6. The key components are vacuum quenched, with high processing precision and long service
life.

7. Widely used in fish feed pellet plants, crab feed pellet plant production lines, shrimp
feed pellet plants, etc.

DSP Fish Feed Extruder Machine Working Principle
The core of extruder machine work is: pretreatment, cooking, and die shaping. The boiler
continuously provides hot steam to the conditioner, so that the mixture is fully cooked and
the nutritional value is improved. The cooking process results in a high degree of
gelatinization of the starch, resulting in good water stability of the feed. The fish feed
extruder is a long barrel with an auger inside, specially designed to subject the feed
mixture to high temperature and steam pressure. When the feed comes out of the mold at the
end of the barrel, the trapped steam is quickly expelled, and the soft and warm pellets
expand to produce low-density floating pellets. Afterward, cutting equipment cuts the shaped
pellets into the required different lengths. The extruder is very versatile and can produce
feed with many different characteristics.

Note: Our fish feed extruder is single screw design. The temperature of the pellets extruded
by the granulator is about 80°C, and the moisture content is 18%-20%. If the output is more
than 500kg/h, it needs to be equipped with a dryer and a cooler. For small volumes, you can
place them in the sun to dry. After placing the order, we also provide the technical formula
for making floating fish feed pellets.
