Pilot scale single screw extruder is widely used for making pellets of different sizes starting from minimum 400 microns to maximum 2000 microns. Pilot scale single screw extruder gives mild compaction and is ideal for most of the Pharmaceutical formulation related to pelletization.
Pilot scale single screw extruder consist of Hopper for loading of wet mass, Hopper as internal blades connected to gear to rotate and push material in a systematic manner in to the feed hopper of Extruder Chamber, Extrusion chamber is Jacketed from outside for circulation of cold water to maintain temperature of the product in case the product is sensitive in nature. Extrusion chamber consist of twin screws which transfer the material towards the pressing cam and out from the perforation of the screen of desired.
Pilot scale single screw extruder is available from R&D to Production batches with minimum output of 250 gms and maximum 150 kgs/hr Pilot scale single screw extruder are cGMP complied equipments with self standing model for Production scale & table top model for R&D scale An a important example for the manifold test methods are Pilot scale single screw extruder with a measuring extruder equipped with a rheometric capillary die head. The relevant data are recorded and evaluated automatically by the Delta software.
