How does pet feed production equipment influence pellets length?

With the energetic growth of modern-day tank farming as well as feed industry, the needs for feed high quality are obtaining higher and also greater. For pellet feed created by animal feed production machine, pellet size is a very crucial quality assessment index.

Cool and also consistent pellet feed not only fulfills the sales requirements of feed producers, but likewise fulfills the real breeding needs of users. Pellets that are as well long, too short or uneven are not for pet feeding. In actual production, the size of the pellets produced by the pet feed production maker is generally called for to be 2 to 3 times the size of the pellets.

For example, granules with a diameter of 3 mm are typically produced with a length of 6 to 9 mm. Certainly, according to actual user needs and also various feed varieties, the length demands are not always within this variety.

Therefore, in order to create feed pellets that meet the needs or as close as feasible to the needs, we will certainly talk about some variables that influence the pellet length of the animal feed pellet making device and also locate the corresponding control approaches to make it beneficial to the production requires, which is important for feed suppliers significance. Based upon years of experience in animal feed granulator style and field debugging, we will certainly discuss this issue from the following aspects.

1. Parameters influencing the animal feed manufacturing machine itself:.

The output of the pet feed manufacturing maker is Q (kg/h), the internal size of the ring die is D (mm), the efficient width of the ring die is W (mm), the direct speed of the ring die is V (m/s), and the rotational rate of the ring die is n (r/ min), the ring die aperture is d (mm), the ring die opening price is m, the number of openings is n ( items), and also the granulation length is L (mm),.

For the above formula, it is uncomplicated to examine the elements influencing the pellet size L of the pet feed production equipment:.

( 1) The influence of the result of the pet feed manufacturing machine.

It can be seen from the formula that the pellet length L is proportional to the result Q. With various other specifications constant, the higher the yield, the longer the pellet, or else the shorter the pellet. For that reason, readjusting the output of the pet feed pelletizer to meet particular pellet length requirements is a feasible alternative. In actual feed production, feed makers do the very same, sometimes compromising huge amounts of outcome to meet pellet size requirements. This issue will be pointed out in the adhering to conversation.

( 2) Impact of ring die line speed or rotational rate.

It can be seen from the formula that the pellet size L is vice versa symmetrical to the ring die straight speed V or the ring die linear rate n. When the feeding rate, that is, the outcome Q, remains consistent, the faster the ring die speed, the much shorter the instantaneously extruded pellets, and also the other way around. For various dimensions of pet feed pelletizers, the rotational speed of the ring die varies considerably.

Generally, the rotating rate of the small animal feed making machine is high, and also the turning rate of the large animal feed manufacturing equipment is reduced, but the direct speed of the ring die is regulated within a appropriate variety, generally in between 6m/s ~ 9m/s, to satisfy the needs of granulation.

When the linear speed of the ring die is tiny, the quality of the pellets is high, however the pellets might be longer than called for, and the line speed is also small, which will affect the output; when the direct rate of the ring die is high, although it is beneficial to boost the outcome, the pellets might be much shorter than the demands, as well as the top quality of the pellets It will become worse, which requires the feed manufacturer to choose its very own ring die line rate according to various feed varieties, as well as realize it by altering the transmission proportion of the pet feed manufacturing machine transmission system.

( 3) Impact of ring die aperture and porosity.

The ring die aperture D has no straight result on the pellet length L, it has an effect on the size L together with the number of openings N, that is, the dimension of the ring die opening up proportion, due to the fact that the opening proportion and also the square of the ring die diameter D and also the variety of openings N is proportional to the product of. The larger the porosity of the ring die, the shorter the pellets, and also vice versa, the longer the pellets. The aperture ratio of the ring die corresponds to different ring die apertures. For example, a ring die has an opening price of concerning 25%, and a ring die has an opening price of concerning 38%.

Normally talking, the larger the pore dimension, the greater the open porosity. In real manufacturing, especially when producing small-diameter pellets, such as 1.8 mm shrimp, some individuals grumble that the pellets are as well long, which is caused by the fairly reduced opening price of the ring die when the aperture is small. One of the services is to sacrifice part of the yield, or to achieve by boosting the line speed of the ring die. In addition, adjusting the cutter is talked about below.
