3.Operation

3.1 Outline of Machine

This machine is designed to mainly cut root vegetables, bulb vegetables, and other food materials into fine dice. The impeller and cutter are driven by a motor to automatically feed and cut the food materials. Allowing a large amount of food to be processed, this is the most suitable machine for various food industries, school meal services, company cafeterias, hotels, and restaurants. This machine uses an inverter to control the motor speed for rotating the dicing cutter. This machine incorporates various kinds of safety switches and protective covers to ensure safe operation.

3.2 Outline of Processing

Food materials (smaller than 3-1/8 inch in length and diameter) are put into the hopper, where they are sliced with the plain blade, while being pressed on the inner wall of the drum with a centrifugal force provided by the impeller. The sliced materials are then cut vertically by a rotating round blade assembly and horizontally by a crosscutting blade assembly, and are finally ejected as diced vegetables. For cutting materials into long sticks, the crosscutting blade assembly needs to be replaced with a bar feeding roller.
