A wet grinder can refer either to a tool for

food grains to produce a paste or batter
. A wet grinder for abrasive cutting uses fluid for lubrication or cooling; for food preparation, a wet grinder combines water to grain as it is ground to produce a batter.

The tabletop wet grinder is derived from the melanger, which was developed by the chocolate industry in the early 19th century.[1]

Abrasive cutting wet grinders

Some angle grinders, most tile saws, and some grinders for sharpening blades used in woodworking are wet grinders. The fluid helps with lubrication of the cutting process and with cooling to avoid cracking or damaging the cutting tool or the workpiece.

Wet grinding is rare in

electric mixers or blenders
. First, the stone grinder generates less heat than a mixer; heat affects the flavor of the food. Second, the stones remain sharp for a greater time than do metal blades.

Types of wet grinders

Originally stones manually operated, modern wet grinders are available for both home usage and larger-scale commercial production. A wet grinder consists of

electric mixers or blenders
. A stone grinder generates less heat than a mixer, and heat can affect the flavor of the food. Unlike mixers, which cut food into smaller pieces, a wet grinder crushes the food, resulting in different consistency.

Dosa is made from a batter obtained by wet-grinding rice and pulses.

    . Melangers typically have a smaller capacity than other industrial mills, so most large makers don't use them; Hershey did, but abandoned them in the 1950s for larger-capacity ball mills. This was about the same time that the electric motor reached India, where melangers were co-opted for making dosas (fermented rice-and-bean creps) because they produce less heat than other mills and preserve the living enzymes in dosa batter.
