The Wet Grinder Defined

A wet grinder is a kitchen appliance with a rotating drum and grinding stones designed for efficiently grinding soaked grains and lentils into smooth batters and pastes.

This is commonly used for preparing batters for South Indian dishes like dosa, idli, and vada.

Wet Grinder Working Principle

A Brief Historical Perspective: Wet grinders have a rich history that dates back centuries.

Their evolution reflects the culinary traditions of different cultures, from ancient India to Southeast Asia and beyond.

The traditional stone grinder has evolved into modern variations, but the core concept remains the same.

Different Components of a Wet Grinder

To understand how a wet grinder works, it’s essential to dissect its components.

1. Grinding Stones: These are the heart of the machine, and are usually natural stones. They rotate and crush the soaked grains or lentils, creating a consistent texture.

2. Motor: The motor powers the grinding stone assembly. Its power capacity varies depending on the type and size of the wet grinder. A powerful motor is essential for efficient grinding.

3. Drum: This is where you place the ingredients to be ground. Drums come in various sizes to suit different needs. A larger drum is suitable for commercial purposes, while smaller ones are ideal for home kitchens.

It uses water to aid in grinding.

Types of Wet Grinders

Wet grinders come in several types, each designed for specific needs.

1. Tabletop Wet Grinders: These are compact and ideal for home kitchens. They are easy to store and offer sufficient capacity for most home cooking needs.

2. Tilting Wet Grinders: They have a tilting mechanism to pour out the batter conveniently. Tilting wet grinders are commonly used in restaurants and professional kitchens.

3. Commercial Wet Grinders: Larger and more powerful, these are used in restaurants and catering businesses. They are designed to handle heavy-duty grinding.

And lately, a new innovative variant of wet grinder is also available in the market – the one with a batter dispenser.

This is essentially a tabletop wet grinder introduced by SmartFingers (a registered trademark of M/s. Mayura Appliance, Coimbatore, Tamil Nadu) that comes with the convenience of a batter dispenser.

With this unique dispenser, you can effortlessly collect your freshly ground batter in a clean and hands-free manner.

What Is Wet Grinder Used For?

Wet grinders have an impressive range of applications:

1. Traditional Dishes: From dosa to idli, vada to appam, many South Indian dishes rely on wet grinder-ground batters. The consistent texture achieved with wet grinding is essential for these recipes.

2. Versatility: Besides batters, many wet grinder models come with an atta kneader and coconut scraper attachments.

3. Healthy Cooking: Batters made using a wet grinder retain more nutrients compared to those prepared using a mixer grinder. It’s a healthier way to prepare dishes as it preserves the natural flavors and nutrients of the ingredients.

Wet Grinder Working Principle

Ever wondered how this appliance works its magic? The wet grinder operates on a simple principle: the grinding stones rotate inside a drum filled with soaked rice or lentils.

The Role of Water: The addition of water is crucial as it helps to attain the desired consistency. This also prevents keeping the temperature of the batter low which can affect the quality of your batter or paste.

What Is Wet Grinder vs. Mixer Grinder

Wet grinders and mixer grinders are often compared, but they serve different purposes.

Let’s delve deeper into this comparison to help you understand when to reach for a wet grinder and when a mixer grinder is the better choice.

Distinct Functions:

  1. Wet Grinder: Master of Wet Grinding Wet grinders excel in one specific task: wet grinding. They are specially designed to transform soaked grains, lentils, and other ingredients into smooth batters and pastes. The primary function of a wet grinder is to achieve a consistent, fine texture that is vital for traditional South Indian recipes like dosa, idli, and vada.
  2. Mixer Grinder: Versatile All-Rounder Mixer grinders are versatile workhorses in the kitchen. They can perform a wide range of tasks, including blending, chopping, grinding dry spices, making smoothies, and even kneading dough. Mixer grinders are the go-to appliance for daily cooking needs, and they can handle both wet and dry grinding.

Unique Applications:

  1. Wet Grinder: Traditional Dishes and Specialty Batters Wet grinders are indispensable for recipes that require soaked grains and lentils. They are a must-have for traditional South Indian dishes where the texture of the batter is critical. The slow, consistent grinding process ensures the desired results.
  2. Mixer Grinder: Everyday Convenience Mixer grinders are your partners in daily cooking. They can quickly whip up chutneys, grind dry spices, make fruit juices, and blend smoothies. They are ideal for tasks like preparing ginger-garlic paste, tomato puree, or grinding spices for your everyday curries.

Texture and Consistency:

  1. Wet Grinder: Superior Texture When it comes to achieving a perfect, silky-smooth consistency, wet grinders have the upper hand. They maintain a low grinding temperature, resulting in batters and pastes with a fine, uniform texture.
  2. Mixer Grinder: Varied Textures Mixer grinders offer flexibility in texture. Depending on your needs, you can control the coarseness or fineness of the grind. This adaptability is particularly useful when you need coarse textures like for meat mincing or a slightly chunky salsa.

Health Benefits:

  1. Wet Grinder: Nutrient Preservation Batters prepared in a wet grinder are healthier than those made using a mixer grinder. It preserves the natural flavors and nutrients of the ingredients, making it a healthier choice for certain dishes.
  2. Mixer Grinder: Quick and Convenient Mixer grinders are designed for efficiency and convenience. While they may not preserve as many nutrients due to the higher heat generated during dry grinding, they are perfect for busy households and quick meal preparations.


  1. Wet Grinder: Careful Maintenance Required Wet grinders require regular cleaning and meticulous care to prevent the buildup of residues and ensure the longevity of the grinding stones.
  2. Mixer Grinder: Easier Maintenance Mixer grinders are relatively easier to clean and maintain, making them a practical choice for those with busy schedules.
