A kitchen mixer grinds, beats, stirs and whips food. It is a more efficient way of mixing ingredients than laboriously stirring with a spoon. A kitchen mixer tap is a tap for a kitchen faucet that mixes hot and cold water as it pours into the sink basin. The faucet connects both the hot and cold water lines to a single valve. There are two types of mixers: a hand mixer, which has two whisks attached to it, and a stand mixer, which uses whisks, paddles, a dough hook and other attachments. A kitchen mixer tap is a one-handled kitchen faucet. The tap mixes the hot and cold water within the faucet body so you can control the temperature of the water with the single handle.
