1、 Working principle of feed dryer:

The rotary drum of the feed dryer is a slightly inclined and rotatable cylindrical body. Wet materials enter from the upper part of one end, dry materials are collected from the lower part of the other end, and hot air enters from the feeding or discharging end and is discharged from the upper part of the other end. The drum is equipped with a forward plate to continuously pick up and sprinkle the materials during the rotation of the drum, allowing them to fully contact with the hot air flow to improve drying efficiency and move the materials forward. The heat source for drying materials is generally hot air, high-temperature flue gas, water vapor, etc. Specific selection can be made based on the properties and quality requirements of the material.

2、 Performance characteristics of feed dryer:

The water evaporation capacity of a feed dryer generally increases with the increase of hot air temperature and changes with the moisture properties of the material. It has higher evaporation intensity than flash drying and spray dryer equipment. The thermal efficiency ranges from 40% to 70%. The equipment runs smoothly and reliably, with no vulnerable parts, few faults, and a long service life, and is widely used in various drying industries.
