how to construct a floating fish feed extruder

Compression section: the slot of screw shallows along the material pushing direction and compresses the material. Extrusion section: screw groove is more shallow, pitch gradually turns smaller, and the extrusion pressure reaches up to 3.0-10Mpa, the temperature can reach 120-150 degrees Celsius.

It is entirely feasible for an extruder to produce floating feed, sinking feed and slow sinking feed by density control; that is more conducive to different fish species. 7.Fine mechanical resistance Feed made using extrusion technology is more resistant to mechanical durability and produces fewer fines in the finished feed during transportation.

During the growth phase, you need to feed your fish and maintain favorable environmental conditions. When the characteristics of water are kept within the optimal range, the growth effect is the best. For tilapia, the recommended water chemistry values are as follows: Temperature: 80-100°F, 85°F is optimal.

This dry type fish feed pelletizer can produce all floating, sinking, and slow sinking aqua-feed pellets just by adjusting feed formulation and degree of expansion. 2. Different molds can be chosen to make pellets with different diameters (0.9-15mm) and shapes.

The function of extruder machine is to change the weight of feed, to make floating, slow-sinking and sinking extruded fish feed. extruder machine manufacturer use fish feed extruder machine produce floating fish feed, sinking fish feed etc. Feed extruder manufacturers to

Commercial fish feed extrusion process refers to cook the mixture of feed ingredients under high temperature, moisture and high pressure by means of fish feed extruder within short time, whereby the high temperature is a direct result of friction (dry extrusion) or

Try some feed for some fish in a pond; keep records of the amount of feed given, the weight of fish at the start and the weight of fish at the end of the trial. Calculate FCR(feed conversion ratio). Multiply FCR times the price of the feed.

During the extrusion process, raw materials would be processed via high temperature, high moisture and high pressure, so at the moment that feed pellets are extruded from die hole, the stress drops sharply and the water content in feed emits from liquid state to gas state, resulting in extruded fish feed.Fish feed production requires higher degree of gelatinization and water stability, starch gelatinization can kill

Fish feeds types: a) Floating Feed –This type of feed floats on water. These feeds go through the extrusion process during processing, so the purchase and manufacturing costs are higher. b) Sinking Feed – This is just the opposite of the former. It will sink directly into the water.

Mixing & grinding: The main raw materials of floating fish feed should be mixed and crushed before make pellets, so FANWAY recommends the related professional equipment – fish feed mixer and fish feed crusher, aiming at producing high quality floating feed with good water stability that is …

Pellet fish feed can be made by ordinary fish feed pellet mill with no extrusion function or fish feed pellet extruder, and the extruded fish feed pellet has an increasingly application to improve fish production.

Working Process of Floating Fish Feed Extruder(Dry Type) When the raw material is sent into feeding device, they will be pressed by the screw shaft with high pressure and temperature which can make the raw material fully cooked and sterilized.
