The solution provided by the present application can increase the production efficiency of batteries.

An apparatus for heating three-dimensional printing filaments comprising a heating chamber including an insulation lining and spool holders mounted at a base of the heating chamber, a heater fan assembly mounted above the heating chamber, wherein the heater fan assembly comprises a powered fan and heater configured to heat air and circulate the heated air to the heating chamber, and a diverter situated between the heater fan assembly and the heating chamber, wherein the diverter splits and directs the heated air to the heating chamber through a pair of channels. The apparatus further comprising a plurality of exhaust ports at top sidewall portions and bottom sidewall portions of the heating chamber, wherein the plurality of exhaust ports allowing the heated air to escape from the heating chamber, and fitting adapters comprising apertures that allow filament material to be dispensed from the heating chamber.

A drying device contains an upper drying head and a lower drying head. The upper drying head is arranged above a transport plane, in which objects to be dried can be transported in a transport direction through the drying device. The lower drying head is arranged below the transport plane. The upper drying head and the lower drying head contain in each case at least one air outlet slot and the longitudinal directions of the air outlet slots essentially extending parallel to the transport plane and transversely to the transport direction, and in which slot planes, in which the air outlet slots extend, intersect the transport plane at angles which are greater than 0 and less than 90.

An apparatus for manufacturing an electrode plate of a secondary battery, the apparatus including a coating unit configured to coat a substrate with an electrode material, a roll pressing unit configured to press an electrode plate coated with the electrode material, and a drying unit configured to dry one of the electrode plate coated with the electrode material and a rolled electrode plate, wherein the drying unit includes a perforated plate with first air holes that are uniformly spaced and uniformly sized for applying heat air to the one of the electrode plate coated with the electrode material and the rolled electrode plate, and a screen with second air holes that are non-uniform, the screen configured to compensate for uneven airflow.

The present invention includes a spray drying disposable device for use in a spray drying system. The disposable has a spray drying head and a plasma drying chamber. The head has a spray dry nozzle assembly in fluid communication with the plasma source and the pressurized aerosol gas source. The pressurized gas flows in a vortex pattern that atomizes plasma droplets in the chamber. The head also includes a plenum has uniform air pressure of the drying gas. A baffle plate forms the floor of the plenum having drying gas jets that supply drying gas to the chamber. The atomized plasma droplets evaporate in the presence of the drying gas emitted from the jets to obtain dried plasma particles and humid air. A capture filter captures the dried plasma particles and allows the humid air to pass. The humid air passes through the gas outlet and the exhaust port.

A vehicle washing system includes a vehicle treatment area that is configured to receive a vehicle to be dried. At least one dryer media device is positioned in the vehicle treatment area. The at least one dryer media device is configured to dry the vehicle upon contact with the vehicle. An air moving assembly is located adjacent to the at least one dryer media device in the vehicle treatment area, and is configured to remove excess moisture from the at least one dryer media device.

A shoe care apparatus includes a chamber for accommodating shoes; a heat pump device including a condenser for heating air to be supplied to the chamber, and a compressor for discharging a coolant to the condenser; a fan for supplying the heated air to the chamber; a temperature sensor for acquiring the temperature of the air to be supplied to the chamber; and a controller. The controller performs a synchronous operation mode controlling the compressor and the fan to operate together, based on receipt of a signal from the temperature sensor, and performs an asynchronous operation mode in which the fan is operated without operating the compressor in response to a predetermined time period having elapsed after the stop of the operation of the compressor.

A decompression drying device includes, in addition to a conventional release valve for introducing external air to restore the inside of a drying chamber to a normal pressure after drying has been completed, a separate external air introduction means for introducing external air into the drying chamber when the pressure inside the drying chamber has reached near a target pressure during a decompression drying process. The decompression drying device is used for drying a pharmaceutical product and, in particular, is used for manufacturing a botulinum toxin dried cake. By introducing external air while finely adjusting its inflow amount when the pressure inside the drying chamber reaches near the target pressure during the decompression drying process, it is possible to prevent a phenomenon in which the pressure inside the drying chamber, particularly the pressure around a vial containing a liquid sample, rises and decreases significantly.
