A novel configuration of a single-beam blue-detuned optical dipole trap based on rapidly rotating laser beam is presented. Large dynamical changes of the potential size and shape were readily obtained due to the simplicity of the trap. A large initial volume provided an efficient loading into the trap and an adiabatic decrease of the trap size yielded a dramatic increase in the atomic density. It was verified that trap stability occurs for rotation frequency higher than the oscillation atomic frequency in the time-average potential.
