A wet grinder is a kitchen appliance used to grind soaked grains, lentils, and pulses into smooth batter for dishes like idli, dosa, and vada. It consists of a rotating drum with grinding stones or blades that crush and blend the ingredients efficiently. Wet grinders are commonly used in homes, restaurants, and commercial kitchens for preparing large quantities of batter uniformly. Made from durable stainless steel or other food-grade materials, they are easy to clean and built for continuous use. Overall, a wet grinder saves time, reduces manual effort, and ensures consistent, high-quality batter for traditional cooking.
