A citrus juicer is a kitchen appliance designed to extract juice from citrus fruits like oranges, lemons, and limes. It typically features a cone-shaped reamer that rotates to press the fruit, allowing the juice to flow into a container. Some models are manual, requiring hand pressure, while others are electric for easier operation. Citrus juicers come in various sizes and styles, including handheld, countertop, and commercial versions. They are popular for making fresh juice, which is rich in vitamins, particularly vitamin C. Using a citrus juicer can enhance the flavor of beverages and dishes, promoting a healthier diet.
