A dough mixer is a kitchen appliance designed to combine and knead ingredients for making dough. It typically features a large mixing bowl and a rotating mechanism that helps blend flour, water, yeast, and other ingredients efficiently. Dough mixers come in various sizes, from small countertop models for home use to larger industrial versions for bakeries. These mixers can be manual or electric, with electric models often offering multiple speed settings and attachments for different types of dough. Using a dough mixer saves time and effort, ensuring a consistent texture and quality in baked goods like bread, pizza, and pastries.
