What should you do when you run into problems with adding water? This article answers in detail.
Regarding the question of adding water
May I ask, if the moisture of the finished product is too low (9), how should water be added?
Add it directly in the mixer? Add hot water? Thank you.
--------------------------------------
Adding water to livestock and poultry pellet feed is asking for trouble. Because the short-term benefits it brings are far smaller than the losses caused by mold and spoilage.
The dry extrusion process can inherently have water added; in the mixer you can add it however you like.
For aquatic feed with a post-ripening process, adding water can be carefully considered after weighing the pros and cons and on the basis of a well-established process: add water in the mixer in the form of a mist..
--------------------------------------
Add hot water and keep the overall moisture below 11, and it should not go moldy, right?
--------------------------------------
Localized moisture is too high
It will still go moldy all the same
--------------------------------------
If it is in spray form, will it cause mold?
--------------------------------------
While adding water, add a liquid mold inhibitor and a surfactant to increase the moisture of the finished product and prevent mold. There are mature products available. If you want to learn more, you can contact me.
--------------------------------------
I would rather have a slightly lower output rate than approve of adding water. The disadvantages outweigh the benefits.
--------------------------------------
To be honest, in winter we always add water
--------------------------------------
It seems it is sprayed during the production process
--------------------------------------
If that is the case
1. Control the moisture of raw materials at acceptance
2. It is best to add water by means of steam
3. When the grinding particle size of the raw materials meets the requirements, use the largest screen hole diameter possible
4. If water is added, the water must be treated, or the water should be added in the form of a mist whenever possible. If this cannot be done, then the process parameters (mixing time) must be modified to mix it as evenly as possible (mold is not only caused by high moisture in the whole batch of feed, because that situation is easy to control; most of the time it is caused by uneven moisture). You can also first add a portion of the major ingredients (corn, soybean meal, rice bran) and then add water and mix first, and then add the other raw materials, though this may have a certain impact on output.
5. Have the day shift and the night shift produce the same variety of feed and see whether the moisture is the same. If there is a change, then make an adjustment in production.

xieThank you. Let me ask again: for the same variety of feed, the moisture now sometimes varies a lot. Is it sometimes because the water was not added in? Will adding water affect output?
