NEW DESIGN FOR DOUBLE CONE BLENDER DRYER USED TO PRODUCE PHARMACEUTICAL READY-TO-PRESS GRANULES

摘要

The present invention relates to an innovative apparatus and its application in the production of granules used in various industries. The said apparatus consists of a double cone blender dryer, which has been modified for horizontal air flow (intake and exhaust) as well as a horizontal line for spraying solution. The process for the production of ready-to- press granules involves blending the ingredients to obtain a homogeneous mixture. Thereafter, a solvent is sprayed using a pump and a spray gun through the hollow rotation shafts for an adequate period of time in which damp granules form. The damp granules are dried with filtered, pre-heated air (heated to an appropriate temperature). A suction fan is used to facilitate air exhaust. The above-said apparatus offers numerous advantages in terms ease of operation, reduced energy consumption and simplicity of cleaning and validation for product change over.
