A dehydrating apparatus suitable for dehydrating food and other biomass products comprises a dehydrating chamber, a vacuum assembly, a magnetron assembly, an infrared heating assembly, a heated air circulation assembly, and a controller. The magnetron assembly is electromagnetically coupled to the dehydrating chamber and is operable to transmit microwave energy into the dehydrating chamber. The vacuum assembly is fluidly coupled to the dehydrating chamber and is operable to reduce the air pressure within the dehydrating chamber. The infrared heating assembly is thermally coupled to the dehydrating chamber and is operable to radiate infrared energy into the dehydrating chamber. The heated air circulation assembly is fluidly coupled to the dehydrating chamber and is operable to circulate heated air within the dehydrating chamber. The controller is communicative with and programmed to operate the magnetron assembly, vacuum assembly, infrared heating assembly and heated air circulation assembly to first reduce pressure within the chamber, then simultaneously transmit microwave energy, radiate infrared energy, and circulate heated air inside the dehydrating chamber upon specific dried product drying procedure.

An airflow structure for a hair grooming device is provided, including a host. The host is provided with a first air chamber is on one side, and a second air chamber on the other side. The first air chamber is communicated to the second air chamber by a communication channel arranged therebetween. The first air chamber is provided with an air intake port, the second air chamber is equipped with a suction device, and a first air exhausting port to communicate the second air chamber to the external environment. The air intake port, first air chamber, communication channel, second air chamber, and first air exhausting port are sequentially connected to form a suction airflow path. Above configuration achieves effective noise reduction and improves user experience. Moreover, the suction airflow path spans across the host, allowing full utilization of space, which facilitates the miniaturized design thereof.

An electrode plate drying apparatus includes a drying chamber accommodating an electrode plate; a support member supporting the electrode plate inside the drying chamber; a lamp portion within the drying chamber and configured to emit drying heat in a direction of the electrode plate; and a reflective portion on a ceiling of the drying chamber and having a portion of a curved shape to reflect the drying heat in the direction of the electrode plate.

A method and apparatus are provided for drying a flexographic plate previously subjected to washing with a water-based or solvent-based liquid. The method involves providing a support member made of a thermo-conductive material, wherein the support member comprises at least a first main surface adapted to allow the support of the plate to be dried. The method involves positioning the plate to be dried on the support element so that a base face of the plate rests on the first main surface. The method further provides the step of heating the support element to a preestablished temperature so that the thermal energy supplied to the support element is transferred by conduction to the plate resting on the support element so as to cause evaporation of residual liquid contained in the plate. The apparatus is provided for carrying out the drying method.
