Horizontal dough mixer is an extruded instant food product basically made from wheat flour. Other flours like groundnut, soya bean or tapioca are also mixed with wheat flour to make it more nutritive. It is very well standardised and simple. Wheat and other flours in small quantity are mixed with around 25% to 30% of water in a mixer for about half an hour and dough is prepared. The paddles are positioned to move the material in opposing lateral directions as well as radically. The paddle design is generally employed where friable materials are being blended.
