  The operation of the individual packaging device 900 will be briefly described. First, each unit starts operating when the power is turned on.

  Next, when an object to be weighed is put into the hopper 901, supply of the object to be weighed from the hopper 901 to the turntable 101 of the weighing devices M1 and M2 is started.

  Subsequently, the object to be weighed to a predetermined capacity is sequentially supplied from the discharge hole 150 of the base 100 to the sealing device 903 by the operation of the weighing device M (M1, M2) as described above.

  The sealing device 903 sequentially wraps the objects to be weighed supplied from the weighing device M (M1, M2) in individual resin bags, seals them, and continuously discharges them outside the device.

  As described above, according to the individually packaged device 900 using the weighing device M according to the present embodiment, the object to be weighed is an indeterminate shape such as a thin ginger or red ginger food that is pickled in sweet and vinegar. Also, the weighing accuracy can be improved, and the individual packaging work can be performed efficiently.

  In particular, it is possible to measure and individually package an unshaped and water-containing object such as sliced ginger or red ginger pickled in sweet and vinegar while removing moisture to the extent that the taste is not lost.
