Vegetables are made every day in our house, but while making vegetables, we remove the peels of the vegetables. By the way, peelers are available in the market for peeling vegetables. Which are also available to us at low cost.

The texture of an ordinary peeler is such that when we peel the vegetables, their peels get scattered around.

But the peeler I am talking about. It is designed keeping this problem in mind. A drum is fitted in this peeler.

When the vegetables are peeled with this Vegetable Peeler Machine, the peel comes in the drum. Which we keep in a safe place.
