Juicers are appliances designed to extract juice from fruits and vegetables. They come in various types, including centrifugal, masticating (slow), and citrus juicers. Centrifugal juicers use high-speed blades to separate juice from pulp, masticating juicers crush and press produce for a higher yield, and citrus juicers are specifically for squeezing citrus fruits. Juicers offer a quick way to enjoy fresh, nutrient-rich beverages.
