An electrohydrodynamic (EHD) drying apparatus includes a non-uniform electric field resulting from an electric field source operable for a high potential, and an electric field source operable for a low potential. A power source is connected to the electric field sources for producing the non uniform electric field for inducing dielectrophoresis (DEP) in an article within the uniform electric field. In particular configurations, the applied non-uniform electric field is for separating a vapor phase being formed during drying from the liquid phase. The electric field source defines a polarizer adapted to produce dielectrophoresis, and the electric field induces coupled electrostatics and momentum for disposing liquid towards the high electric field for drying.

Disclosed herein is technology related to a heater device and corresponding systems and method. In examples the heater device has a frame having a base structure and a support beam. The support beam extends upward from the base structure. The frame is translatable across a ground surface. A cantilevered elongate heater extends from the frame. The elongate heater has a proximal end and a distal end, where the proximal end is coupled to the support beam of the frame. In some examples the elongate heater has a first heater element rotatable about an elongate axis central to the elongate heater. Additionally or alternatively, a plurality of heater elements are coupled to the cantilevered beam.

Embodiments disclosed herein provide a bucket assembly and method of use thereof. The bucket assembly is a relatively lightweight and removable apparatus that can fracture cut, paddle, and heat contents contained therein. The bucket assembly can include a housing that has a curved metal plate and blade array attached thereto. A cut and paddle assembly can rotate within the housing and interface with the blade array to fracture cut contents contained therein. The cut and paddle assembly is also operative to mix the contents to ensure full dispersal within the housing. A flexible heater array is attached to and operative to heat the curved metal plate. The combination of the fracture cutting, paddling, and heating can convert organic matter to a ground and selectively desiccated product.

Various implementations include a biomass dehydration system including a wet biomass chamber containing wet biomass, a belt or chain defining one or more cavities, two or more pulleys including a drive pulley that the belt or chain extend around and that are configured such that the cavities are disposable within the wet biomass chamber as the belt or chain moves along the pulleys to cause wet biomass to enter the cavities, and a drying chamber for dehydrating wet biomass disposed in the cavities into solid pellets. The drive pulley engages the belt or chain and causes the belt or chain to move around the pulleys. At least a portion of the belt or chain extends from the wet biomass chamber through the drying chamber. One of the pulleys includes one or more ejection protrusions for engaging the cavities and ejecting solid pellets from the cavities.

A heater assembly is disclosed. The heater assembly has a frame that has a first and a second opening. There is a heater element located in the first opening. A flow valve is mounted to the frame and movable from a first position to a second position. In the first position, the flow valve blocks airflow through the first opening. In the second position, the flow valve blocks airflow through the second opening. When the flow valve is between the first and second position the flow valve blocks at least some airflow through the first opening and blocks at least some airflow through the second opening.

A heating plate is included in an electronic device which also includes a processor, a detecting unit, and a battery. The detecting unit detects values of electrical current in certain parts of the electronic device. The processor determines whether any of the detected values falls within a predetermined range. If the detected value falls within a predetermined range, the processor enables a connection between the battery and the heating plate to cause the heating plate to micro-heat the electronic device to promote or accelerate the evaporation of water or moisture in the electronic device. A method for water and moisture disposal by internal heating is also provided.

The cosmetic brush dryer comprises a base unit, a water pan, a drain panel, one or more brush stands, and a top cover. The cosmetic brush dryer may dry one or more cosmetic brushes. As a non-limiting example, the one or more cosmetic brushes may be wet after being used and cleaned. An air moving device in the base unit may blow air through a heating element and the warm air produced may circulate around the one or more cosmetic brushes within the top cover. Water dripping from the one or more cosmetic brushes may pass through the drain panel and may be collected in the water pan. An electrical timer in the base unit may energize the air moving device and the heating element for a predetermined time interval.
