Abstract

PURPOSE: In the formation of tablets parts where a granular resin is in contact with air are enclosed and the closed system if filled with a dried gas other than air that dissolves in the resin to prevent bad appearance of tablets and void formation in tablets.
CONSTITUTION: A tablet press composed of hopper 2, top force 4 and fottom force 4 is enclosed in insulated box 7 and the inside is made air-tight. Then a dried gas other than air that dissolves in resin 1 is introduced into the box 7 to fill up. Pipes 8 are embedded inside hopper 2, top and bottom forces 4, 4' and a cooling gas is circulated to keep always resin 1 at -65 to 5°C. Under these conditions resin 1 is made into tablets.
EFFECT: Titled tablet press gives tablets free from bulge, snake eye, pinhole and void inside the tablet.
