What particle hardness is appropriate for piglet feed?
About the particle hardness of piglet feed
Recently, a salesperson complained that the company's piglet feed was rather hard. At first I didn't believe it, but later I found samples from November and December, chewed them in my mouth, and at the same time measured the water disintegration time. In the end, it turned out to be true: the piglet feed pellets from December were harder than those from the previous month. You should know that the formula for these two months was the same. The ring die was replaced with a new one at the end of October. I have been thinking about this issue recently, so please help me find the cause.
--------------------------------------
Hehe, of course a new ring die is a bit harder!!!
--------------------------------------
Factors affecting pellet hardness, when only the die and the season are changed, the main factors that can be considered are:
One may be the ring die,
Two may be that the corn is dry.
--------------------------------------
A new ring die generally gives greater hardness; it can be pre-punched
--------------------------------------
Just passing by to learn, but if the corn is dry, it seems pelleting is difficult and shaping is not easy, so how could it be hard?
--------------------------------------
I also raised this issue on the forum, and everyone had no specific measures to control hardness, and relevant research materials are also very scarce.
--------------------------------------
I misread it. Attention should be paid to the relevant parameters during conditioning.
--------------------------------------
I also think it is the ring die. Is it not punched well? Or not punched at all? Is the pelleting temperature too high? Has the whey powder changed? Is the lactose content too high?
--------------------------------------
By winter the corn is dry

The moisture content of the corn now is 1 to 2 points lower than when it was just harvested
Recently in production we need to take the ring die over to be punched
--------------------------------------
Just passing by to learn and add some knowledge, thanks

Last night, we used the punched ring die to produce piglet feed. This morning we compared the water disintegration speed with that before punching. The increase in water disintegration speed was not obvious. The November batch had the fastest water disintegration speed.
It seems that the moisture content of corn is a very important factor.
In addition, we used the punched ring die to produce poultry feed, and the appearance of the poultry feed was much smoother than before.
