Cylindrical Grader

Product Details:

Cylindrical grader.

McKinnon Cylindrical Graders grades the coffee through a combination of wire and perforated screen sections. The machine is modular in construction, and individual sections can be replaced, interchanged, or redesigned. The type of coffee and amount of each grade determine the length of each modular section. An internal spiral conveyor conveys the coffee along the cylinder in a very uniform manner. Cleaning brushes ensure maximum screening at all times. All sections are made of perforated sheets when no peaberry separation is required. The grader is configured with alternate wire and perforated sheets when peaberry separation is required. The graders are provided with input hopper with slide feed regulation device, individual outlet hoppers for each section, rails and hooks for bagging, and spouting for further transport. Cylindrical Graders are suitable for Arabica and Robusta varieties. Input capacities range from 200kgs per hour to 2000kgs per hour. Graders can be configured to give up to nine separations, and with twin or triple deck for easy repass, and movement of coffee
