Abstract: A control system includes a motor, an interface circuit, a motor controller and a detection control circuit. The interface circuit receives and converts a pulse width modulation signal. The fan dissipates heat when the motor is operated in a forward rotation mode and eliminates dust when the motor is operated in a reverse rotation mode. The detection control circuit reads a duty cycle of the converted pulse width modulation signal in real time. When the motor is operated in the forward rotation mode, the detection control circuit drives the motor controller to control the rotation speed of the fan according to the duty cycle. If the duty cycle is lower than or equal to a first threshold value, the detection control circuit drives the motor controller to switch operation mode of the motor from the forward rotation mode to the reverse rotation mode.

Abstract: Disclosed is an electrostatic spray drying process for encapsulating a core material, such as a volatile flavor oil, within a carrier or wall material. The process is achieved by atomizing a liquid emulsion comprising the core material and the wall material, applying an electrostatic charge at the site of atomization, and drying the atomized emulsion into an encapsulated, free-flowing powder. Applying an electrostatic charge at the site of atomization allows the spray drying to be accomplished at significantly reduced temperatures, in particular, inlet temperatures in the range of 25° C. to 110° C., and outlet temperatures in the range of 25° C. to 80° C. The low drying temperatures impart improvements in the resulting encapsulated powdered product, including better retention of volatile flavor components, a flavor profile comparable to that of the starting liquid formulation, and better hydration and dissolution in water-based applications.
