• Fish feed pellets are the popular feed in modern
commercial fish farming, providing balanced nutrition
needed by fish stock and improving fish farm
environment. Due to high price of feed pellets on the
market, many farmers tend to purchase fish feed
extruder to produce pellets by themselves to low the
cost. Here dry type fish feed is recommended for feed
pellet production, which is the the specialist contributing
to high quality floating fish feeds without steam
conditioning of the raw material. With advanced single
screw extruder by belt drive, floating fish feed machine is
the ideal device in small and medium size feed
processing plants and aquafarms.

4. Spotlights of Dry Type Fish Feed
Machine
• 1. The fish food extruder is widely used for producing floating feed pellets of
all kinds of aquatic animal, sinking and floating aqua-feed pellets both can
be made just by adjusting feed formulation.
• 2. Different molds can be chosen to make pellets with different diameters
(0.9-15mm) and shapes.
• 3. Advanced technology and humanized design ensures easy operation and
reliable performance, high efficiency, low power consumption.
• 4. Electric heating device is adopted to improve the feed expansion rate and
pellets floating time.
• 5. Auto-temperature control system makes the temperature controlling more
direct viewing and the parameter more precise.
• 6. High temperature and high pressure process can kill the salmonellosis
and bacterial infections in materials and also makes the pellets easier to
digest and absorb
• 7. Dry type fish feed extruder does not need the steam boiler, so the dry
type pellet machine is cheaper and easier to use and operate compared
with wet type pellet machine.

6. Difference between Dry Type and
Wet Type Extruder
• 1.Dry type fish feed extruder does not need the steam
boiler, so the dry type fish feed pellet machine is cheaper
and easier to use and operate.
• 2. The feed pellet made by wet type fish feed pellet
machine is more smooth and with better quality because
the material is ripen and mixed enough in the conditioner
compared with the dry type extruder.
• 3. The capacity of the dry type feed pellet machine is
lower than the wet type fish feed pellet machine, so
usually the dry type fish feed pellet machine is better and
economic for the small and medium size user or factory.

8. Advantages of Dry Pellet Feed
• Storage: can be kept for two to three months when stored in a
covered cool dry place.
• Hygiene: expansion process can eliminate most bacteria. Low
moisture content (about 10%) can prevent bacterial growth.
• Nutrition: can be added with animal or plant protein, fish oil or other
fats, vitamin complex and minerals required by specific fish species.
It is highly nutritious and can effectively improve the health of fish
stock.
• Environmental impacts: using pellet feed of appropriate size and
density can lower the loss rate and significantly mitigate the
environmental pollution caused by the feed residues.
• Notice: Pellet feed of different sizes and densities can be made to
accommodate the needs of species in various growth stages and
with different babits. By using pellet feed of the appropriate size and
density, loss rate and environmental pollution caused by the feed
residue can be significantly reduced.

Working
• There is no need to heat outside the dry type machine,
through the screw extruding of the raw material, heat is
produced and gathered during the rotary working
process in the airtight environment, and during the high
temperature ripening process, the starch and fiber of the
raw material become swell. Then under the pressure-
tight condition, material will be formed into pellets by
shaping mould. At the end, through the high pressure
produced by the regular rotating of the screw, after being
cut by the forepart cutter which rotates regularly and
high-speedily, the finished products will be shrunk and
become small average puffed balls in room temperature
and pressure.
