The BR-150 allows researchers and new product developers to easily evaluate the effectiveness of low pressure basket extrusion. The
BR-150’s size and unique features allow it to evaluate small batch sizes, while generating product indicative of a full scale production system. The BR-150 can be easily assembled with the desired screen and prepared for extrusion. A wet mixture is separately prepared manually or in a small batch mixer. The wet mixture is manually fed into the feed hopper and falls by gravity onto the pressure blade. The pressure blade is a scraper-like device that prevents bridging at the hopper discharge and directs the material into the extrusion zone. The extrusion blades gently wipe the material through the screen, yielding well formed extrudates.
