4. Operating Instructions
The Bircher Drum is designed for efficient and fine grating. Follow these guidelines for optimal results.
4.1 Grating Fruits and Vegetables
This drum excels at finely grating softer fruits and vegetables like cucumbers, carrots, and apples, perfect for salads or muesli.
- Wash and peel ingredients as necessary. Cut larger items into pieces that fit comfortably into the grater's feeding chute.
- Place a bowl or container beneath the grater's output chute to collect the grated food.
- Feed the ingredients into the chute and use the food pusher to gently guide them towards the rotating drum.
- Operate the grater according to its specific instructions (e.g., turn the handle for manual models, activate power for electric models).

4.2 Grating Nuts and Harder Ingredients
The Bircher Drum is also effective for grating nuts, chocolate, or hard cheeses into fine textures.
- Ensure nuts are shelled. For very hard nuts, consider pre-soaking or lightly toasting them to soften slightly, if appropriate for your recipe.
- Break chocolate or hard cheese into smaller, manageable pieces.
- Follow the same feeding and operating procedure as for fruits and vegetables. Apply steady, gentle pressure with the food pusher.
