The variable speed motor 27 ″ is a driving gear for the rotating bodies 10 ′ and 10 ′.

[0020]

According to the present invention, when the formed rice in the rice forming hole is lifted by the elevating plate in the rice shaping machine as described above, the elevating plate does not stick to the outer periphery of the formed rice and the inner periphery of the forming hole. In addition, there is an effect that the weight of the formed rice can be accurately measured by the weight measuring device together with the lifting device.

Further, the supply of the rice feeding device can be corrected and controlled to a set value by a signal by a comparison operation between the measured value and the set value.

By forming the rice forming hole in a vertically movable mold form, stickiness between the guide through hole and the mold form is eliminated, and the measuring accuracy can be obtained only by slightly raising the form.
As a result, the measuring efficiency can be improved.

Further, when the measured value is low, it can be replenished by a rice replenishing device. In general, the error between the set value and the measured value of the formed rice can be reduced, and rice shaking with good weight accuracy can be obtained, and the amount of wasted rice in mass production can be reduced.
