What are the factors that affect the quality of feed pellet?
In recent years, with the development of feed industry , feed pellet machine is widely used in live
stock and fisheries, andfeed pellet . Thus, pellets manufacturers must improve the quality of feed gr
ain to meet the needs of the market. ButWhat are the factors that affect the quality of feed pellet?
There are several factors affecting the quality of feed pellet, such as feed formulation, steam conditio
ning and grinding. Steam conditioningis probably the most important factors affecting the quality of feed pellets. Studies have shown that it plays a role in 20% of the overall quality factors of feed pellet
In order to achieve the desired conditioning effect, feed manufacturers must consider the moisture
modulation time and conditioner .
Moisture
Studies have shown that moisture addition to the feed to produce a positive impact on the conditioning
process. Water is used in durable pellets forming materials and additives appropriate agglomeration is
essential. It also helps to ease through a die by reducing friction material passage. Improving gelatiniz
ation to be achieved by appropriate addition of water.The key to get good quality feed pellets is to tar
get conditioned feed moisture about 16.517.0%, and maintain this moisture at all time.If the manufact
urers have a good control of moisture content, they will havea better chance to produce high quality pe
llets consistently.
Modulation time
Optimal modulation time for any particular regulation is to reach every time the feed heat and moisture
desired particle core center. A long time so that a greater degree of gelatinization modulation, which can
improve the durability of pellets. Typically, 1530s sufficient for conditioning. Specific modulation of param
eters depending on the formulation and granulation machine models. Some special types of pellets requires
highly gelatinized before granulation.
Therefore, it takes a long time modulation. Under normal circumstances, aquatic feed, animal feed need long
term modulation time.Some attention needs to be paid to the pickup angle configuration and regulator shaft,
it will affect the speed modulation of time. By adjusting the regulator to a parallel set of picks, a 5 point incr
ease in the durability of pellets can be achieved , which will increase the quality of feed pellets.
Conditioner Type
The double shaft conditioner offers a definite advantage over the single shaft conditioner due to the two conditi
oner shafts, which are dissimilar in diameter and rotate counter to each other. The counterrotating shafts are la
den with picks set at varying angles, which causes the feed to be mixed evenly in the conditioner barrel. The m
odulation time can reach up to 240 seconds, and the degree of ripening is 5060%, which can meet the requirem
ents of special feed pellets. Besides, there are fewer residues in the conditioner.
A conventional conditioner with a single shaft and a single barrel must be large enough to achieve the proper
modulation and mixing time. it could meet the conditioning requirements of some ordinary feeds.
