Sorting products by weight using air

To sort unwanted parts out of a product flow, FoodeQ has developed a sorting shaker that uses an airflow to separate heavier pieces from lighter ones. This application sorts the stems out of cut kale. The heavier stems drop down, while the lighter kale particles are carried across an opening by the air. The system is also suitable for other products, such as popcorn, where unpopped kernels can be sorted out.
