A citrus juicer is a kitchen appliance used for extracting juice from citrus fruits like oranges, lemons, and grapefruits. It typically works by pressing or spinning the fruit against a cone-shaped or ribbed surface that separates the juice from the pulp and seeds. Citrus juicers come in different designs, ranging from manual handheld squeezers to electric models with various features such as adjustable pulp settings and multiple juicing cones. Investing in a citrus juicer can make it easier to enjoy fresh and healthy citrus juices at home, without the hassle of squeezing fruits by hand.
