Meanwhile small fish feed mill/floating fish pellet mill machine particles adjacent the screw will rotate along with screw's rotating, causing every particle adjacent the screw will rotate along with screw's rotating, causing every particles insides the chamber to posses different speed. Therefore, relative movement among particles creates heat which is necessary during manufacturing because of helping protein change properly, damage cold oil ,decrease plasticity, decrease oil, elasticity, resulting in high oil productivity.

The all-wet process uses raw coconut rather than dried copra, and the protein in the coconut creates an emulsion of oil and water.The more problematic step is breaking up the emulsion to recover the oil. This used to be done by prolonged boiling, but this produces a discolored oil and is not economical. Modern techniques use centrifuges and pre-treatments including cold, heat, acids, salts, enzymes, electrolysis, shock waves, steam distillation, or some combination. Despite numerous variations and technologies, wet processing is less viable than dry processing due to a 10-15% lower yield.
Proper harvesting of the coconut makes a significant difference in the efficacy of the oil-making process. Copra made from immature nuts is more difficult to work with and produces an inferior product with lower yields.
small fish feed mill/floating fish pellet mill machine Conventional coconut oil processors use hexane as a solvent to extract up to 10% more oil than produced with just rotary mills and expellers. They then refine the oil to remove certain free fatty acids to reduce susceptibility to rancidification. Other processes to increase shelf life include using copra with a moisture content below 6%, keeping the moisture content of the oil below 0.2%, heating the oil to 130-150 °C (266-302 °F) and adding salt or citric acid.

Introduction for Floating fish feed pellet extruder machine

It is widely used for producing maize flour, soybean flour or compound powder, wheat bran into high grade aquatic feed pellets for fish, catfish, shrimps, dog,.cat etc. The puffing fish feed pellets can float on the water surface for over12 hours without water polution. According to your requirement and production scale, floating fish feed machine can be classified into dry type machine and wet type machine.

Working principle for floating fish feed pellet extruder machine

After the material is sent into feeding device, they will be extruded and expanded by the screw shaft with high pressure and temperature which makes the raw material fully cooked and sterilized. Then the expanded material will be formed into pellets by shaping mould. You can change different moulds to make pellets with different diameters. After that a cutting device will cut the formed pellets into different length as required.

Features for floating fish feed pellet extruder machine

1.According to different requirements, variety shapes of high-grade feed pellets for fish, shrimps .etc
2.The finished pellets can keep floating for 12 hours without pollution to water.
3.The floating time can be controlled by the puffing degree adjustment
4.Floating fish feed machine can make pellet from diameter 1mm-12mm just by changing the mould.
5.Electric heating device is adopted which can improve the feed expansion rate and pellets floating time.
6.High temperature and high pressure cooking process can kill the salmonellosis and bacterial infections and
also makes the pellets easily to digest.
7.The cutting device can be adjusted to make pellets of different length.
8.The wet type machine needs a boiler to make steam which can conduct steam to the conditioner and ripen the raw material in advance.

Q: What’s the difference between dry type machine and wet type machine?

A: The biggest difference is the wet type need a steam boiler while the dry type doesn’t. In this case, the dry type is cheaper than wet type, and the feed pellets made by wet type extruder is much smooth and with better quality.

Q: What kind of raw materials should I use to make fish feed?

A: soybean meal,wheat meal,corn meal,flour,bone meal,meat meal,fish meal etc.Finess in 60-80mesh.

Q: How long does the floating fish feed float on the water?

A: The feed pellets made by our extruder can float on the water surface for over 24 hours.

Q: Can this extruder produce poultry feed pellets?

A: Yes. It can make floating and sinking aquatic feed, pet food with different shape, poultry feed pellets.

Q: Is there a formula of making fish feed pellet?

A: It totally based on the situation of your fish. We can offer free formula to our customers.
