A continuous freeze dryer having a hopper for supplying product to the inlet of the freeze-drying chamber via a sealed coupling with the inlet. A hopper valve allows the hopper to be sealed and evacuated with a product to be freeze-dried inside. An inlet valve of the freeze-drying chamber and a hopper valve may both be opened to provide a pathway between the hopper and the chamber whilst the hopper and chamber are maintained in an evacuated condition. The hopper may include an internal shell within an external shell with an evacuation port for evacuation a cavity between the shells. A hopper valve allows the supply of product to the freeze dryer via a hopper port. Product may be loaded into a hopper, coupled with the inlet of the freeze-drying chamber, evacuated, a hopper valve opened to supply product to the freeze-drying chamber, and the product conveyed through the freeze-drying chamber.

In order to create a conveying system which is of simple construction and enables an efficient conveyance of objects, it is proposed that the conveying system comprises a first conveying device and a second conveying device, wherein the objects are able to be taken over from the first conveying device and/or are transferrable to the first conveying device by means of the second conveying device.

A paint drying device where leakage of air between a drying chamber and a driving section accommodating chamber is prevented reliably. In the paint drying device in which the drying chamber and the driving section accommodating chamber communicate with each other via a through hole through which a power transmission tool extends, there are provided an air feeding passage for feeding air present outside the drying chamber to the driving section accommodating chamber by an air feeding fan and an exhaust passage for discharging air in the driving section accommodating chamber to the outside of the drying chamber by an exhaust fan. An air amount adjustment device is provided for adjusting a ratio between an amount of air to be fed to the driving section accommodating chamber via the air feeding passage and an amount of air to be discharged from the driving section accommodating chamber via the exhaust passage.

A method and device for drying wood chips to be used as raw material for a gas-generating reactor, the device being disposed between the storage for wood chips and the reactor. Product gas of the reactor is at least partially used in a block-type thermal power station (BHKW), and hot air from the housing of the block-type thermal power station is used to heat and dry wood chips in a drying hopper which has at least one outlet for the cooled humidified air. The wood chips enter the drying hopper through a first air-tight lock and exit the drying hopper through a second air-tight lock.

In order to provide a treatment installation for treating workpieces that is of simple construction and enables optimised workpiece treatment, it is proposed that the treatment installation should include a treatment chamber and a conveying device, by means of which the workpieces are suppliable to the treatment chamber, are removable from the treatment chamber, and/or are conveyable through the treatment chamber in a conveying direction.

A dryer for drying veneers including a plurality of sections in which drying means for drying the veneers are present, wherein at least one of the sections there is a means for generating a negative pressure in the respective section.

A microwave drying device has a processing box. Two mounting openings are formed on an external mounting wall of the processing box. Two suction partitions are mounted in the processing box and divide an inner space of the processing box into a microwave drying space and two suction spaces. The microwave drying space is located between and connects to the two suction spaces. Multiple channel partitions are mounted in the microwave drying space to form a meandering wave travelling channel. Two opposite ends of the wave travelling channel connect to the two mounting openings respectively. Two microwave emitting modules are mounted on the external mounting wall and emit microwaves toward the two mounting openings respectively. Multiple openings are formed in the processing box such that a film can travel through the processing box. Therefore, drying speed is greatly increased, and the drying device is more compact.

A method for manufacturing a fabric with an intelligently-designed digitally-printed pattern with energy saving effect is disclosed. It includes S1: knitting a cotton yarn, a bamboo fiber yarn, and a mulberry silk yarn into a silk-cotton plain knitted single-sided fabric; S2: subjecting the fabric to a double-sided singeing; S3: mercerizing the fabric obtained in step S2; S4: subjecting the mercerized fabric to a neutralizing processing, a bleaching processing, a deoxidating processing, and a whitening processing in sequence; S5: setting the base color of the fabric obtained in step S4; S6: subjecting the fabric obtained in step S5 to a sizing and setting treatment, a pattern design treatment, a digital printing, a steaming treatment, and a water washing treatment; S7: subjecting the fabric obtained in step S6 to a soft setting; S8: subjecting the fabric obtained in step S7 to a decating treatment; and S9: pre-shrinking the fabric obtained in S8.

The electrode drying device includes a transfer unit that transfers an electrode sheet having an electrode slurry coated onto the current collector, and a drying chamber including an inflow port where the electrode sheet transferred by the transfer unit enters, wherein an interrupting member for adjusting the flow amount or flow velocity of outside air flowing in a drying chamber is formed at the inflow port, and a height of a central part of the interrupting member is different from a height of a peripheral part of the interrupting member.

The present disclosure discloses a vacuum drying tank, including a shell and a pumping device. The shell includes a first shell part, a second shell part, and a third shell part; the second shell part has an accommodating cavity provided with an opening in the top; an air pumping hole is formed in the accommodating cavity; the first shell part is, hermetically covered at the opening; the third shell part is arranged below the second shell part; the pumping device is arranged in the third shell part and is communicated with the air pumping hole; and the pumping device is used for pumping out air in the accommodating cavity from the air pumping hole, so that the accommodating cavity is in a vacuum state.
