The Drying Range or VDR (Vertical Drying Range) is one of the most demanding processing machinery in Woven dyeing & printing plants. The Drying Range has the following features that make it an essential part of the plant. Firstly, It ensures rapid drying of fabric at high steam pressure.

Drying is defined as a process where the liquid portion of the solution (moisture content) is evaporated from the fabric. This is done after de-watering of fabric. The water dispersed in a textile material by a chemical–physical process is generally eliminated by the action of hot air, which makes the water evaporate.
