Moisture of raw material content and temperature of granulation process affect the quality of pellets, The temperature of pellet machine can adjust the moisture of materials.

With the developping of enconic, more people use the corn-type formula. The moisture of corn is around 15, the water is high, the moisture of the semi-finished products is relatively high, and the steam can not be added in the manufacturing processing of pellets. After the quenching and tempering, it can reach 16.5.

The user of feed pellet plant said: “When granulating, the temperature is kept between 61 and 65 ° C, and the moisture after mixing is measured to be 13.2%. After the quenching and tempering, the moisture is 16.5%, and the moisture after cooling is 13.6%. Is the water content of the raw material high? The pressure after decompression is 0.32Mpa.”

Some people also said: "1. it is estimated that the raw material moisture is too high, it is necessary to measure the moisture of the grain storage bin; 2. The steam pressure is properly adjusted, the moisture can reach 18% after quenching and tempering; 3. The cooler material level is properly adjusted (according to the season) To control the moisture of the finished product."

How to solve the problems?
Modulation is crucial for the granulation temperature in according to research; or the steam inlet can be changed to 2-3; the user also observes the feed pellet machine, such as the pellets shapes and quality. The steam is normally installed with temperature measuring instrument. The blocking phenomenon have occured, which means that the problem of steam quality is caused by excessive water content. The user need to carry out the debugging of the steam valve.

The current condition is whether the current of the feeder is too large, which causes the granulation temperature to not go up; the other is to carry out the debugging of the steam valve, improve temperature or extending the quenching time and increasing the pulverization.
