The Machine based on planetary gear train theory, inside the Material barrel, the blender conducts revolution and rotation around the mixer shaft at the same time, and this provides a compact conformation and reliable speed variation. Under such a condition, the materials inside could be mixed fluently and evenly. And different range of rotational speeds, thus it is suitable for the mixing and blending of various kinds of food. The blender models from our company adopt belt-driven instead of the traditional worm-gear-driven. The latter might, in a short time, emit overmuch heat, lose excessive energy with a weak electric motor; moreover, worm-gear-driven belt has difficulties in maintenance and cost much. While belt-driven is able to overcome the above defects of worm-gear-driven belt, it has little dissipation in energy and its noise is very low. Our products absorb the advantages of notched belt roller (obtain national patent already)，providing reliable transmission, more power(compared with similar machine models), more economical and convenient maintenance, as well as easier operation and cleaning process. As one of the most frequently used equipment for quality pastry, this series blender is widely applied in hotels, canteens, and pastry workshops etc.
