Notes

What impacts the outcome of feed pellets?<br>
Pellet mills can be used to make feed pellets. Feed pellets can be crazy of grains, cereals, beans, corns, whey powder, oil and also ingredients. Owing to different residential properties of raw materials, the feed pellets result is various. It is affected by the oil, crude fiber, wetness, starch web content.



Adding oil

Include a percentage of oil (0.5% ~ 1%) to the raw materials The oil can reduce the wear of pellet mill components, and make the raw products easier to pass through the die holes, so as to raise the outcome of pellets.




Yet when included with more than 2% oil, the raw materials will be loose and tough to develop. Consequently, if you want to add high dosage of oil, you would certainly better add 30% of it in the blending procedure and 70% in the pelletizing process.



Crude fibers in the raw products.

When the crude fiber content in the raw materials is between 3% and 5%, it will certainly add the bonding of resources, raise the developing price, and reduce the breaking rate of pellets.



However if the unrefined fiber content is greater than 10%, its reduced glue force will decrease the firmness as well as creating price of the pellets. Besides, it will escalate the mechanical wear of the pellet device.



Dampness material

High wetness web content of the raw products will certainly affect the temperature rise throughout pelletizing, as well as reduced the result and also quality of pellets. On the other hand, it will certainly cause the raw products to slide in between the roller as well as level die, and also block the holes on flat die.



As a result, the dampness content of raw materials need to be less than 13%. If biomass pellet maker is higher than the requirement, you must decrease the vapor added in the pelletizing process.




Protein content

Raw materials with high protein material has far better plasticity after home heating, high viscidity, as well as high outcome. Yet if the raw products consists of high non-protein nitrogen, the feed pellet outcome is reduced.



Starch web content

Grains has high starch content. It is very easy to create at high temperature and high water material, and also the pellet output is high. For solidifying, the moisture web content ought to be 16% -18%, and the temperature needs to be more than 80 ℃. Otherwise, the starch gelatinization degree is poor, the wood pellets will be very easy to break or even incapable to develop.



If the grains have been healed (like dry cone) prior to solidifying, the pellet manufacturing will certainly be low. So it is not advise to select dried out grains.



Heat-sensitive feed

The heat-sensitive feed consists of lactose and whey powder. After heating, the viscosity will certainly enhance, to make sure that the production boost. Yet when feed machine for poultry go beyond 60 ℃, they are simple to coke as well as obstruct the holes on die, so that the production decreases. As a result, this kind of feed can be toughened up with warm water.



Inorganic feed

Inorganic feed has little adhesion and inadequate pelletizing performance. Therefore, if the raw products contains way too much not natural web content, you need to include some binders to boost the pelletizing effect, so regarding increase the output.



Nevertheless, one of the most essential point is to pick an appropriate kind of pellet mill according to your demands. Do not blindly pursue high manufacturing. You can start with small-scale production. After having some experience and steady revenues, you can enlarge your production scale and acquisition more tools.
