Short Answer 
A grain grinder is a kitchen tool that transforms hard grains into various forms like dough or powder, offering versatility in cooking. It operates by crushing grains through a hand-turned lever, allowing users to control the texture, though its limited capacity may require careful planning for larger quantities.
Step 1: Understanding the Purpose of a Grain Grinder
A grain grinder is a specialized kitchen tool designed to process hard grains sourced from various plants. Its main purpose is to transform these grains into different forms such as dough, paste, or powder. This allows cooks to incorporate grains into various recipes using different culinary techniques.
Step 2: How the Grain Grinder Works
The operation of a grain grinder involves a simple yet effective design. Grains are fed into a tube, which directs them to the crushing area. Here, they are crushed when the user turns a lever in a clockwise direction. This hands-on process enables the user to control the grinding texture and consistency of the grains, resulting in a versatile ingredient for cooking.
Step 3: Acknowledging Limitations and Usage
While the grain grinder is a useful tool, it does come with certain limitations. One significant drawback is its capacity for grain load; users can only process a limited amount at a time. Consequently, users must plan their grinding sessions accordingly, which might require additional time for larger quantities.
