WHERE TO USE


Techno Designs offers RVD for clean, simple and effective way of drying of wet cakes, wet powders, slurries where either solvent is to be recovered or drying is to be carried out at relatively low temperature for heat sensitive material.

CONSTRUCTION


It contains a hollow shaft with specially designed hollow arms, which are heated by steam / hot water/ thermic fluid; rotating in a centrally jacketed shell. The entire shell area is effectively covered by the specially designed scrapper arms, which scrape the entire internal surface of the dryer and continuously move and rotate the material remaining in contact with hot surfaces for protracted periods of time. This reduces the drying time.

OPERATION


After starting agitation, feed is charged and vacuum is applied in RVD, dust catcher, condenser and receiver. Then heating the mass causes vapor to evaporate, which is subsequently condensed and collected in receiver. The recovery of solvent is maximum and drying time is low because of higher heat transfer, vacuum and intensive mixing.

SALIENT FEATURES


As each material is unique in nature, Techno Designs offers pilot trial for understanding drying behaviour and predicting data on power and heat input along with drying time. Optional features like breaker bar (for minimizing lump formation for particle size reduction), nitrogen purging (for explosion proof environment), stationary scrapper blades ( for scrapping rotating agitator for highly sticky material), sampling valve (for collecting samples during vacuum application), flame proof motors (for Ex-proof environment)
