Production links may cause mildew mainly to exceed the finished moisture exceeding the standard. The moisture exceeding the standard is divided into an average moisture exceeding the standard and partial moisture. There are several such situations that cause the finished moisture exceeding the standard. The following cases are summarized: TIM China feed industry information network – based on feed, serving animal husbandry
The average moisture of finished products exceeded: [ 123] TIM China Feed Industry Information Network – Based on Feed, Serving Animal Husbandry
During the production process, due to the failure of the raw material, the failure of the drying or cooling system exceeds the standard Thereby, the phenomenon that triggers the early mildew of the feed, because the average moisture of the finished product will be processed after the average moisture is detected, and will not flow into the market. (If the product control department is not well controlled.) However, during a small batch production process, since the granulating temperature has not been adjusted to normal, the granulation is completed; the particles leave the ring die temperature Low, the temperature in the cooler is also low, and the activity of water molecules in the feed is weak, which is not easy to exist. In addition, the temperature of the cooler is thin and the resistance of air flow is small, and the temperature is faster when the feed is cooled to room temperature, but the moisture is not existed, resulting in moisture exceeding the standard. This phenomenon is easy to appear in winter or early spring, and the rainy weather in the autumn is easy. Rework processing This material (under conditions with low temperature and low temperature), if you do not match the low moisture, it is difficult to reduce moisture to a qualified level. In this case, some plants have to continue to receive, so that the stock time is long after a long time. The solution can be started from several aspects:

(1), control raw material moisture (mixed raw material moisture summer 12% -14%, 10% -11.5% in winter).

(2) To enlarge production bulk, to determine the minimum safety production batch according to granulator and cooler according to different specifications, In terms of granulator, the mass production batch is normal, the amount of the granulated amount is less than 25% of the total amount of the batch (and the particles required for the precaution of 50 ¡ã C before the tether temperature. Come out; for the minimum safety production batch for the cooler is the whole batch to achieve more than 60% of its capacity in the cooler.

(3) The granulator is started first on the steam pipeline condensed water; and often check the pipeline Whether the water supply valve is normal.

(4) By adjusting the equipment and process parameters such as mass insulation, improve steam saturation, improve the temperature of the temperature , Control granulationThe feed amount extension the time of the particles in the ring mold hole (to increase the temperature of the particles from the ring mold), and the material level height of the cooler is increased, and the reasonable damping level can be controlled to control the finished moisture within a certain range.
