ABSTRACT:
A system for cleaning or separating particles that uses a controller or computer to precisely control the cleaning or separating process. By carefully monitoring and controlling the separating process, an improved degree of separation is achieved. In the preferred embodiment, the invention controls a particle separating machine which uses upward airflow in a channel to separate less dense particles from heavier or more dense particles. Upward airflow is induced in the channel by an airflow means. A wind speed sensor measures the air velocity in the channel and communicates this data to a controller. An operator inputs targeted or desired upward air velocity to the controller. The controller commands the airflow means to increase or decrease airflow in the channel so that upward air velocity in the channel remains comparable to the targeted upward air velocity input from the operator. Particles entering the channel are separated to a high degree because of the precisely controlled airflow.
