PURPOSE:To uniformly preheat even a large tablet up to the core part thereof and to effectively remove the moisture in the tablet by providing a preheating apparatus due to high frequency heating and preheating the tablet under rotation. CONSTITUTION:When a tablet is preheated, a push-up bar 30 is raised to the heating position within a guide cylinder 24 and a rotary actuator is driven at that position to be rotated around the axial line of the push-up bar 30. The tablet is rotated in the guide cylinder 24 to be subjected to high frequency heating. It is pref. that an uneven surface 30a is formed to the upper end surface of the push-up bar 30 because the tablet is stably rotated. When preheating is stopped, the driving of the rotary actuator is stopped and the push-up bar 30 is raised to the setting part provided to the upper part of a heating part 10. |
