Shandong low - cost transfer of used drum dryer

Drum dryer (also known as drum dryer, rotary dryer, etc.) is a contact type internal heating conduction type of drying machinery. In the drying process, heat is transferred from the inner wall of the drum to its outer wall, passing through the dried food materials attached to the outer wall of the drum, and evaporating the moisture on the materials. It is a continuous drying production machinery. Working principle edit the drum of drum dryer is a slightly inclined and rotatable cylinder. Wet materials enter from the upper part of one end and dry materials are collected from the lower part of the other end. Hot air enters from the feed end or discharge end and is discharged from the upper part of the other end. The cylinder is equipped with a forward feed plate, so that the material can be continuously picked up and sprinkled during the cylinder rotation, so that it can fully contact with the hot air flow, so as to improve the drying efficiency and make the material move forward. The heat source of drying materials is generally hot air, high temperature flue gas, steam, etc. The working process of the drum dryer is as follows: the feed liquid to be dried flows into the receiving tank of the drum dryer from the high position groove, and the material is attached to the drum surface by the film distributing device. The drum is filled with heat supply medium. The food industry mostly uses steam with the pressure of 0.2 ~ 6Mpa and the temperature of 120 ~ 150 ℃
