An automatic drying method for a grain dryer has a preparing step, a parameter-setting step, and a multi-stage drying step. The preparing step includes preparing an automatic drying device. The automatic drying device has a body, at least two drying sections, and a detecting module. Each drying section has a hot air inlet, a net-layer base, and at least one exhaust pipe. The detecting module is connected to the body and has at least two moisture meters, at least two temperature sensors, a rotary unit, and a processing unit. The parameter-setting step comprises setting a temperature value and a moisture content of each drying section. The multi-stage drying step comprises conveying pre-dried grains into each drying section, importing hot air into each drying section to dry the pre-dried grains, and adjusting an operating speed of the rotary unit and the temperature of the hot air.

An apparatus for drying wood veneer includes an elongate drying chamber including a conveyor for conveying material to be dried from an input end to an output end; and a cooling section for cooling veneer leaving the output end of the drying chamber, the cooling section including a pressure controller for maintaining a pressure in the cooling section that is slightly higher than pressure in the drying chamber while maintaining a near-zero pressure differential between the drying chamber and the cooling section.

A drying apparatus includes a dryer for a textile web. The dryer includes a drying chamber and at least one air-permeable drum arranged to rotate in the drying chamber. The textile web is guidable over a partial section of the circumference of the drum and heated drying air is flowable through the textile web. The dryer further includes a device to introduce heat for heating up the drying air. The device includes an internal hot gas source and an external hot gas source. The internal hot gas source is a component of the dryer and the external hot gas source is arranged peripherally to the dryer and includes a hot gas line connected at least indirectly to the dryer.

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.

Provided is a flexible air supply damper system for preventing an overdrying-caused defect of a secondary battery electrode plate, the flexible air supply damper system including: a fluid supply unit supplying a fluid; a heating unit heating the fluid supplied through the fluid supply unit; a drying unit drying the electrode plate while receiving the fluid heated through the heating unit; a damper unit splitting the fluid passing through the heating unit to control an amount of the fluid to be introduced into the drying unit; and a discharge unit through which the fluid used in the drying unit and the fluid split out of the damper unit are discharged. By controlling the amount of the fluid to be introduced into the drying unit, the electrode plate is prevented from being overdried.

An air dehydration and heating device can include a first evaporator serpentine and a second evaporator serpentine in parallel and in series with at least one condenser serpentine; a first outside air intake damper for the first evaporator serpentine and a second outside air intake damper for the second evaporator serpentine; a fan motor to drive a fan; a drying air outlet duct to receive air moved by the fan, the air having passed through at least one of the first evaporator serpentine and the second evaporator serpentine and at least one of the at least one condenser serpentine; a return drying air intake damper in a return drying air intake duct; and a processor to control temperature and humidity of drying air in the drying air outlet duct.

A method of drying print agent is disclosed. The method comprises blowing hot air onto an absorbent printable medium that bears water- and/or solvent-based print agent to reduce the viscosity of the print agent and to promote absorption of at least some water and/or solvent in the print agent by the printable medium; and, subsequent to the blowing of hot air, irradiating the printable medium with ultraviolet radiation to dry the unabsorbed portion of print agent on the printable medium. A printer ink drying apparatus and a print apparatus are also disclosed.
