dry type fish feed extruder is suitable for small- or
medium-scale fish farms and fish feed industry, for processing
shrimp feed, prawn feed, floating fish feed, sinking fish feed
pellets and pet feed pellet.
working principle of dry type fish feed
under the action of the frictional force of the principal axis
and flat-die, the compression roller spins. the high temperature
between the roller and die ripens the starch of the materials, and
the protein becomes congealed. then the fish feed is extruded from
the holes of the die. fish feed pellets are conveyed out of the
extruder. additionally, we can choose the length of the feed by
regulating the angle of the cutting knife.
features of dry type fish feed pellet
1.simple structure, widely used, small flooring space, low
2.we can use dry powder materials to make feed pellets without
adding extra water into the dry type fish feed extruder. the dry
pellet feed is convenient to store.
3.the dry pellet feed is well processed which is easy for the
animals to digest. during the process, the pathogenic microorganism
and parasites are eliminated.
4.this fish feed pellet extruder also applies to make pellet
feed for rabbits, ducks and the like. whats more, the pellet feed
is more economical than the compound mash feed.
5.there are many different press molds you can choose in
according to the size of the pellet that you need.
6.the raw materials used in producing pellet feed is
tips of dry type fish feed extruder
1.stay away from the feed inlet when fish feed extruder works.
if you want to add materials into it, you should be with the help
of a stick, not your hand.
2.we should add materials before turning on the machine. and
leave some materials in the extruder when you stop the machine in
case the express roller and die mold directly touch each
3.if the machine gets stuck, we should turn down the machine
4.we should loosen the bolt of the express roller after
5.check the degree of tightness of the belt to prevent the
belt slipping and decrease the capacity.
6.add and replace the lubricating oil regularly.
7.it is normal that the temperature of engine rises to 70
degrees after a long continuous working.
