An important factor in the feed production process

Mildeways of feed have always been in one of the many problems of feed manufacturers. In order to prevent mildew, ensure that the quality of feed, each manufacturer has adopted a lot of effective measures, and has achieved Very good effect, the reason for mildew is affected by many factors, and the flexible dys in the feed production process is only one of many factors. In actual production inventory we found that there is an even feed during a short storage period (10d ~ 20D), even shorter time has local mildew phenomena, and in other conditions meet the requirements of the requirements (such as Water, anti-mold, environment, temperature, humidity, storage, etc.), one of the sources of mildew is caused by the imperfection of production processes.

Currently, the process flow in the production of particle feeds in most feed production plants is: After the cooler begins to increase the cooled feed to a certain height, then uninstall into the finished grading screen. Sie, the hierarchical screen is divided into three different material layers by two-level screen, and the uppermost screen is not qualified, the intermediate layer is a qualified finished product, the lowermost screen is set to unqualified, qualified finished products Flowing into the finished product bin, waiting to be packaged. In the case of unqualified, the lower two layers will be summarized to feed back to the granules. Through long-term observations, summarizing the mildew factors caused by this process, on the material of the uppermost screen, we know that the powder of the granulator is strictly pulverized, we know, through the system The powder of the pellet machine is a strict pulverized mix, screening treatment, the particle size is small, and after the ring mold granules, the material flowing out from the ring-shaped hole is not greater than the ring mold. The material flowing out of the hole is not greater than the outer dimensions of the normal product of the ring mold. That is to say, the graded feed is allowed to pass all over the hierarchical screen, and there is no sieve production (even if there is an except for the ultra-long granules that have been cut off), in the actual production, the uppermost screen is indeed Some sieves are produced. By collecting these sieves to observe the analysis, it is not difficult to find that in addition to individual long particle feeds, it is mainly composed of two materials: 1 from the granulator to the partial circulation equipment to fall off the part ( Such as gaskets, nuts, etc.); 2 is a high-water bobbine and closed fan formed on a high-water tunnel and a chassis formed on each circulation process in a granulator to a graded sieve and a chassis, cooler, and hoist, etc. Some of the detritional cakes accumulated in the equipment. These material groups are much higher than that of the normal-produced particulate feed due to long-term water, and the reproduction of molds has created a favorable conditions. When these block flows back to the granule, it is again After granulation, they will enter the finished product, and once these high-moisture particles enter the finished packaging bag as the goods, it will produce two unfavorable factors, and the particle color is significantly different from the normal finished product, and most of the variants After feeding the animal, there is a poor reflection, causing corporate image damage, and user investment; second is due to these particlesThe amount of water is generally much higher than that of normal qualified particles, and some have metamorphic phenomenon, so it is easy to induce mildew in the short-term, due to microbial metabolism, once mildew water will increase, accelerate feed mold Under the vicious circle, the in-pack feed is placed in the short term.

In summary Both animals should not return to the granulator again, but should be treated as a waste residue. Solution: Add a three-way on the backflow tube of the uppermost screen material to add two cases to two cases. In the case of a reservoir (because the material is very small, it can be cleaned once a day); The warehouse is broken. Practice has found that this method is inhibited by the mildew caused by the process, and has received a better effect.
