The invention discloses a novel high-efficiency mixer. The novel high-efficiency mixer comprises a device main body, a main mixing frame, a fixed raised block, a water tank, a water pump, a first speed reducer, a control switch, a feeding port, an inner blade, a reverse rotation blade, a fixed bearing, a second speed reducer, a reverse rotation auxiliary motor, a discharge valve and a main motor.The main motor is arranged above the device main body. Compared with the existing mixer, the novel high-efficiency mixer has a scientific and reasonable design. Through forward rotation of the main motor and intermittent reverse rotation assisting of the reverse rotation auxiliary motor, the materials are fully stirred, the stirring time is shortened and the stirring efficiency is improved. The novel high-efficiency mixer has a nozzle so that through feeding of an appropriate amount of water in the stirring process, the mixing efficiency is improved and the cleaning effects on the blade ensurethe service life of the blade and thus the novel high-efficiency mixer is widely used in various occasions.
