A combination weighing device includes: a storage unit that stores time-series measurement values sequentially acquired by the measurement hoppers; a time measurement unit that measures an elapsed time from a timing corresponding to supply of the products to the measurement hoppers until a timing at which the time-series measurement values enter a region considered to be stabilized when the time-series measurement values stored in the storage unit converge to the region considered to be stabilized as a stabilization time until the measurement values become stabilized; and a selection unit that acquires the stabilization times by the time measurement unit over a plurality of cycles and can select a recommended stabilization time that is the stabilization time in which a predetermined measurement accuracy can be maintained based on a standard deviation of the acquired stabilization times for the plurality of cycles.

A weighing system for weighing particulate material such as powders, granules and the like, and particularly particulate foodstuffs. The system includes: a weighing device (9); a vibrator unit (11); a transfer receptacle (7) having an opening; a robotic arm (5) arranged to move the transfer receptacle (7); and a control system (13) arranged to control the robotic arm (5) and the vibrator unit (11); wherein the transfer receptacle (7) is arranged to receive a quantity of the particulate material through the opening; the control system (13) is arranged to actuate the robotic arm (5) to move the transfer receptacle adjacent the weighing device (9), and to actuate the vibrator unit (11) to vibrate the transfer receptacle (7) thereby causing particulate material located in the transfer receptacle (7) to dispense from the transfer receptacle onto the weighing device (9).
