Well, Commercial Machines are dependent upon a 60 Second minimal wash and rinse time.
But that depended on the machine. The smaller the machine (Like UM-4) had a 3/1/2 min. wash and rinse cycle.
Depended on the model.
Rack conveyors worked on Feet per second. Once you got past a Door Type Machine, the larger machines may have not required a pre spray rinse. Pending on the model.
