Encountering this problem, many friends must immediately think that this situation will also occur when their feed pellet machine is making feed pellets. This is really a headache. It not only wastes raw materials, but also greatly increases the screening of feed pellets. difficulty. Today, Jimco technical experts will discuss with you what are the reasons for this phenomenon.
Recently, many customers have reported that the pellet machine produces a lot of powder, and the pellets produced are not compact enough, and the feed pellets made are always soft, so what is going on? Jimco technical experts interpret it for you.
In general, in this case, consider the reasons for feed ingredients or formulations? Production changes come more slowly, or change the recipe, and the desired results can be achieved quickly. Excluding the reasons for feed ingredients and formulas, let's analyze whether it is an internal problem in the machine settings.
1.The wear degree of the mold is too large, the sieve holes are ground flat, and the expansion is serious, which reduces the pressure on the particles, affects the forming rate of the particles, and causes too much powder.
2.The moisture content of raw materials is too low or too high. If the water content is too high, the powder will not be too much, but the hardness of the pellets is low, and the pellets produced by the feed pellet machine are easy to loosen. If the raw material has low water content, it will be difficult to extrude and form, resulting in too much powder.
3. The feed pellet machine is aging, the power is insufficient, the motor cannot provide enough speed, and the corresponding pressure is generated to press into pellets.
4. The quality of the ring die is not good, or the compression is not too high.
5. Consider the amount of oil used
6. The feeding scraper is not installed correctly, and the material cannot be fed into the pressing chamber.
7. The position of the cutter is wrong, and the discharge material is extruded into powder (but if the hole is often blocked, it is unlikely).
8.Moisture control is to comprehensively control various factors according to different situations in the whole process of production, so that the final moisture content of the product can reach the expected target of the producer. The main factors that affect the final moisture content of the feed product are: the moisture content of the feed material itself, the moisture change in the crushing stage, the liquid addition amount in the mixing stage, the moisture content of the steam, the level of conditioning, the size and thickness of the die hole of the die, The air volume and drying time of the cooler, the packaging quality management, the influence of different climatic and environmental factors, etc. (Generally, the moisture of pellet feed after processing should not be higher than 12.5; but in the north, it can be not higher than 13.5. If pellet feed is processed in summer, due to the high ambient temperature, the best moisture of finished pellets should not be higher than 12.5, otherwise prone to mildew deterioration).
Feed pellets have been welcomed by more and more farmers and herdsmen because of their unique advantages. They are convenient for storage and transportation, and are also conducive to animal digestion. Compared with ordinary feed, they are rich in nutrients, so the market prospect is very good. In fact, the production process of feed pellets is a process of proportioning, as long as this ratio is well controlled. Of course, when you first make pellets, you will definitely not be proficient, but it is good to do it twice. Generally, the feed pellet machine manufacturer's manual will explain the proportion of feed pellets, which can be referred to below.
