Donut mixer using bevel gears transmissions with 18 kg/hour in capacity

Abstract

Small scaled donut productions use hand mixer to mix flours, eggs and another dough contents. The usage of this mixer was followed by some obstacles, such as the plastic material astigmatism worm gearbox that resulting the edge of gears has friction loss. Metal material bevel gearbox may overcome the dough stirring problem. This gearbox is able to overcome big load and high spin. As a result, the capacity of stirring container is able to be maximized that increasing working productivity result. There are a few things must be designed in scheming of the design process, such as the scheming of shaft calculation, bearing, bevel gear transmissions and frame. The results show that the production capacity increase 225 % from 7 kg/hour in capacity using hand mixer to 18 kg/hour in capacity.
