[Operation and effect] The rice fed on the belt conveyor (4) is leveled by the leveling roller (25) to a substantially uniform height and is conveyed to the downstream side. The rice stops at the position corresponding to the clamping dies (51) (51), the clamping dies (51) (51) approach each other, and the rice is pinched against the spring (56). The rice is formed into a shape corresponding to the recess (52) of the tightening die (51).

After the mold is clamped, the molds 51, 51 are opened. At this time, if the clamping die (51) is not biased by the spring, the clamped rice may be pulled by the die while being attached to one of the dies (51). In the present invention, by striving diligently to overcome this point, by biasing the clamping die (51) in the clamping direction with a spring, when the clamping die (51) (51) is opened, the rice It succeeded in eliminating about 100% of being pulled by the mold. The reason for this is not clear, but it is considered that when the clamping die (51) is opened by an air cylinder or the like, the clamping die (51) slowly separates from the rice by the compression amount of the spring.

When the clamping die (51) is opened to the standby position, the belt conveyor (4) is activated to convey the clamped rice to the downstream side. The above operation is repeated for each intermittent operation of the belt conveyor (4), so that the rice can be efficiently clamped into a predetermined shape.
