Seed-counting machine

Seed counting machines (Seed counters) count seeds for research and packaging purposes. The machines typically provide total counts of seeds, or batch sizes for packaging.

Traditionally, the seed packaging industry packed seeds by weight using weighing scales. Seeds were packed by weight while sold as units.In order to assure the correct quantity of seeds, seed distributors added a safety margin to the packed weight.This safety margin results in loss of revenue. The seed counter is a uniquely appropriate solution for items that are sold by units as opposed to weight.
