The invention relates to an evaporation dryer (1) for drying particles, having—a process chamber (10) with at least one product inlet (11) for supplying the particles to be dried into the process chamber (10) and a product outlet (12) for discharging dried particles from the process chamber (10), —a heat exchanger (20) arranged within the process chamber (10), —having at least one inlet (21, 211) into the heat exchanger (20) for pressurized steam as process steam and at least one condensate outlet (22, 222) from the heat exchanger (20), wherein—the at least one condensate outlet (22, 222) is connected to an expansion tank (30), wherein at least one pump (40) is connected to the expansion tank (30), and the expanding steam is pumped out of the expansion tank (30) and supplied to the process steam.

The production method includes a drying step of drying a particulate crosslinked hydrogel polymer obtained by polymerizing a monomer, which is a material of a water-absorbent resin, using a heating device to obtain dried particles. The heating device includes: a rotary container that contains the particulate crosslinked hydrogel polymer therein and rotates; and a plurality of heating tubes that are located within the rotary container, extend in an axial direction of the rotary container, and rotate together with the rotary container. A gel temperature of the particulate crosslinked hydrogel polymer to be subjected to the drying step, the gel temperature being measured by a contact thermometer, is not lower than 50° C.

An apparatus for drying bulk particulate material, and having an inlet chamber for receiving a moist bulk particulate material and an outlet chamber for ejecting a dry bulk particulate material. The inlet chamber comprises a steam permeable bottom being divided into a number of subsections including a first subsection and a second subsection. Each subsection defines a first and a second radial centreline. The first subsection and the second subsection each having at least one louvered plate section comprising a plurality of louvers arranged in a first and a second specific direction, respectively, for directing superheated steam in a first and second blowing direction, towards said lower cylindrical inner wall. The specific direction of the louvers of the first subsection defines a first angle in relation to the first radial centre-line, and specific direction of said louvers of said second subsection defines a second angle in relation to said second radial centreline, and said first angle and/or said second angle, being different from 0 degrees.

A mobile steel grit dryer used to dry steel grit may be configured with a number of different functions and features to assist a contractor in performing steel or other structure maintenance when using steel grit in resurfacing the structure. The steel grit dryer may be configured with a heat process vacuum bypass so that an off-board vacuum, such as a vacuum on a grit recycling system, may be utilized as opposed to having an onboard vacuum. The dryer may include multiple modes so that an operator may use different modes for different environmental conditions. An exoframe may provide for better durability when being transported to different jobsites. A variety of automation and safety features may also be provided to simplify and improve safety for operators.

A drying apparatus based on peristaltic propelling, including a heat supply module, a drying chamber and a conveying device. The conveying device is arranged in the drying chamber. The drying chamber is provided with a heat source inlet, a heat source outlet, a feeding port and a discharging port. A heat output point of the heat supply module is arranged at the heat source inlet and is configured to provide heat to the drying chamber. The conveying device is configured to provide a platform for laying and propelling a material. The conveying device includes a platform formed by alternate stacking of at least two grid groups. A gap is provided between two adjacent grids. The gap is kept unobstructed and the material is flipped when the material is propelled forward. The gap formed between the adjacent movable grids facilitates improving the fluidity of the air, enhancing the drying efficiency.
