What should I do if the pellet output rate for large chicken feed is too low?
Help: the pellet output rate for large chicken feed is too low.
Corn 672, soybean meal 150, flour 50, corn gluten meal 50, limestone powder 15, calcium hydrogen phosphate 9, lard 38, premix 20
Conditioning temperature 80, compression ratio 12-15 both tried. The output rate is very low, with a quarter to a third being powder or very small broken pellets. Corn moisture is not high either, 13-14.
I don't know the reason. Previously this formula's pelleting effect was still okay, but problems appeared in the last month.
--------------------------------------
In your formula you use flour - is it actually flour or wheat middlings, and has the purchasing channel changed? Also check whether the cutter and ring die are worn and need replacement. In addition, check the steam line. I think it may be caused by too low moisture content during conditioning, and it needs to be readjusted; the temperature can be raised a bit higher. I am not very familiar with production, so this is all I can think of, for your reference.
--------------------------------------
It is flour. Where do you think the problem could be if that is the case?
The scraper and ring die are definitely fine. As for steam, reaching 80 degrees should be about enough.
I really can't think of anything else...
--------------------------------------
Too much oil is added. Generally, the amount of oil added during pelleting does not exceed 2%; if it exceeds that, it is recommended to spray it on after pelleting.
--------------------------------------
Previously this ratio could still make good pellets.
--------------------------------------
I think you added a bit too much corn.
--------------------------------------
There is no major problem with the formula. From a nutritional standpoint, the limestone powder may be a bit much. This formula is very similar to our current formula. Have the circuits been checked? Is the speed sufficient? Could it be that the wiring or voltage is insufficient, so it can't drive it anymore?
--------------------------------------
Too much oil and fat is added. The process parameters are fine. Check the ring die.
--------------------------------------
You are using a lot of lard. The quality of lard is unstable. See whether it is different from the previous batch. With so much oil added, you could consider using some fat powder. Imported ones include Germany's BSB, and domestic ones include Jiangsu Taixing's. It can improve pellet quality.
--------------------------------------
I have also encountered this problem. Later it was found to be caused by changes in the texture of two raw materials, namely soybean meal and standard flour.
