A leading global food processing equipment manufacturer needed a robust geared motor solution for a line of tempura batter mixers. The machines gently mix a precise ratio of chilled water and bagged ingredients for a set amount of time to ensure that the batter achieves the ideal consistency. After the tempura is mixed properly, it is transferred, via an on-board pump, to an adjacent batter applicator. Geared motors are used to drive the rotating mixing cage as well as the positive displacement pump.
Based on previous successful collaborations the OEM contacted Bauer for a reliable solution. After careful review of the specific application requirements, Bauer supplied modified Model BK17 and BK08 geared motors to drive the machine’s mixer and pump.
The BK models feature PMSM (permanent magnet synchronous motor) that reduce heat losses from the rotor by 100% and total losses by approximately 25%, while increasing total efficiency by 10% or more. For the PMSM user, this improved performance translates into lower total cost of ownership, a reduction in CO2 emissions, and ongoing savings that buffer against future increases in energy costs.
The five versions of the batter machines in the line have high startup torques and run at different speeds. Because PMSM motors provide efficiency at a wide range of speeds, instead of stocking five different geared motors, the OEM was able to use a single BK model for all of its batter machine models.
All BK Series models are completely enclosed and sealed against dust and water spray. A 3-piece internal sealing system between motor and gearbox ensures leak-free performance of the high-speed input seal in all mounting positions. Units feature a torque rating up to 18500 Nm and output speeds up to 280 min-1.
