ABSTRACT:
A method and an apparatus for manufacturing tablets of moist powder which is produced by adding an additive agent such as an excipient or a binder to medical ingredients, further adding a solvent such as water, ethanol or the like, and kneading the mixture. The tablet manufacturing method comprises the steps of: preparing a first table and a second table which are intermittently rotated and driven relatively with respect to each other; supplying moist powder from a hopper into filling holes of the first table; filling the supplied moist powder into mold cavities of the second table under a pressurized condition by means of filling pins of a filling and pressurizing device at a location where the first table overlaps with the second table; relatively moving the first and second tables with respect to each other so as to level the surface of the moist powder in the mold cavities by removing the excessive powder; chamfering the surface of the moist powder by a finish-forming device; drying the moist powder by a dryer; and releasing the moist powder out of the mold cavities by a release device.
