Wet grinder, a grinder used with water. Wet grinders have a wide application in industry, workshops, and commercial and domestic kitchens throughout Africa and Asia. Kitchen wet grinders are very popular tools in the South Indian kitchen used to make paste out of soaked grains and lentils.
At one time, a wet grinder consisted of a large rock with a hole in it, where a cylindrical rock with a wooden handle fit in. The grain and lentil mixture was poured in with water and the cylinder rotated by the handle on the top to grind the food together. The ground paste is used for various food items like idli, dosa, sevai and vada.
The evolution of grinders have a dramatic change in the working. The earlier form of wet grinder called "Attan Kallu" used mechanical energy in which the user had to rotate the top stone called "Kullavi" to grind the medium. The invention of electricity led to the development of electric-powered wet grinders. By this invention, the powered wet grinders have both the top and the base stone rotating. These electric models were first introduced in restaurants, and later moved into the home.
Most modern models still have stone components for the grinding action. The stone is usually granite. The old manual grinding stones used to be refinished for better results. Modern stones usually don't need refinishing, as they last much longer.
Despite these advances in bringing technology into Indian kitchens, there are limitations.
