"Simultaneously with the stepwise filling of the bins 64, seed is delivered through the lower bin outlets 124 and slide gate assemblies 126. Flow of seed is controlled by the slide gate assemblies 126, which move between full-closed and full-opened positions. The bins 64 are filled and emptied using known loss-in-weight techniques, in cooperation with the seed wheel assembly 44, so that a substantially even supply of seed is delivered to seed treater 46. This in turn allows computation of the precise amount of seed delivered to the treater 46, thereby providing certified seed weights to a buyer, without the need for a separate weighing step."

Lo de compuerta (gate) puede tener sus dificultades, bien puede tratarse de un dispositivo como una lengüeta (más preciso). ¿Tienes algún esquema)

Supongo que se trata de una máquina para el tratamiento de semillas en la que el agente de tratamiento se dosifica mediante la cuantificación de la gravimetría/pérdida de peso de las semillas. Una máquina como la que se muestra en: https://uscllc.com/sites/default/files/2020-08/TD-09-06-1054...
