Special belt dryer for pellet feed, mesh belt dryer for extruded feed
Special belt dryer for pellet feed, mesh belt dryer for expanded feed,pellet feedWorking principle of the dryer：
After being heated by a heat exchanger inside the dryer, the air enters the dryer under the push of a circulating fan. After the drying medium exchanges heat and moisture with the materials on the conveyor belt, part of the air is discharged through the public air duct, and the other part of the air is reheated by the heat exchanger, and mixed with fresh air enters the dryer again.
The material is evenly spread on the conveyor belt through the spreader, and enters the dryer with the conveyor belt. After drying once, it turns back in the material return section and enters the lower conveyor belt for secondary drying or multiple drying, and then discharged.
Special belt dryer for pellet feed, mesh belt dryer for expanded feed,pellet feedMain structure of dryer：
Performance indicators:For floating expanded aquatic pellet feed produced by templates with a diameter of 3mm or 4mm, when the hot air temperature of the dryer is 120 ° C, and the moisture drops from 22% to 24% to 8% to 10%, the dryer throughput and moisture unevenness indicators comply with Table 1. In view of the differences in composition, moisture content, environmental conditions and final product requirements of the materials processed by the dryer, changes in the above-mentioned performance indicators may be caused.
Main structure of the dryer:The belt circulation dryer is mainly composed of legs, feeding section, drying section, returning section, conveyor belt, spreader and other parts.
