A machine or device for chopping vegetables and fruits that is to be used directly or canned. Some vegetable cutters are designed for use in the home. Commercial vegetable cutters are used by restaurants and in industry. The simplest type of vegetable cutter consists of a metal screen with blades and two handles. A more complex type is designed not only for cutting but also for shredding, grating, and juicing. In such a device, interchangeable (usually disk) blades are attached to a shaft that is turned manually or electrically. Commercial vegetable cutters are driven by electricity and are designed for a productivity of 200 to 3,500 kg per hr. There are many different models of commercial vegetable cutters, each designed for chopping a particular vegetable. The principal parts of a vegetable cutter are the loading hopper (feeder), the reducing agent, the shaft with attached blades, and the drive. Vegetable cutters usually have a set of disks with different blades for cutting, shredding, and grating.
