A super absorbent polymer drying apparatus is disclosed. The super absorbent polymer drying apparatus is a drying apparatus equipped with a conveyor for drying the super absorbent polymer, and may include: a conveyor for transferring the super absorbent polymer; and a hot air supply part for supplying dry hot air to the conveyor, wherein the conveyor may include a plurality of conveyor beds connected to each other in a bent state, a link connecting part for connecting between the plurality of conveyor beds, and a driving part for driving the conveyor beds.

A through-air apparatus for drying or bonding paper, tissue, or nonwoven webs is provided. The apparatus includes a web-carrying structure configured to move and a first component having at least one sealing element adjacent the web-carrying structure, where the sealing element is configured to reduce the infiltration of ambient air into the through-air apparatus. The apparatus also includes at least one channel configured to direct air to the sealing element to reduce the infiltration of ambient air into the through-air apparatus. A method of operating a through-air apparatus for drying or bonding paper, tissue, or nonwoven webs is also provided. The method includes directing air to a sealing element to reduce the infiltration of ambient air into the through-air apparatus.

Drying of newly harvested grain wherein the grain has a preferred market moisture content target and the grain is heated and dried to within about four percent above the target and discharged at about 110° F. Thereafter, the grain is cooled to ambient by circulating ambient air at preferably one third of a cubic foot per minute per bushel through the grain thereby removing about two percent additional moisture. When required the grain is further dried to target moisture utilizing an equilibrium moisture process.

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 machine for processing textile substrates includes a base configured to receive a substrate support carrying a textile substrate, and may further include a nozzle assembly supported above the base for applying pretreatment liquid to a pretreatment area of the substrate during relative movement between the nozzle assembly and the substrate support along a conveying direction. A forced air assembly is supported above the base for movement transverse to the conveying direction. A controller that controls the relative movement between the substrate support and the nozzle assembly along the conveying direction, or the movement of the forced air assembly along the second axis based on information related to a pretreatment area or a print area of the textile substrate in order to direct heated air from the forced air assembly onto an area of the textile substrate substantially corresponding to the pretreatment area or the print area.

A drying hopper for drying granular material includes a hopper casing defining a plenum chamber for granular material, and an upper part and a bottom part. The hopper also includes a material inlet for the granular material arranged in the upper part; a material outlet port at the bottom part; a component for introducing hot drying gas into the hopper casing; and a gas outlet arranged in the upper part. The component for introducing hot drying gas includes gas pipes arranged to extend substantially vertically in the upper part, each gas pipe having a gas outlet port at its lower end and being connected at its upper end to an annular gas duct having a gas inlet for receiving a flow of drying gas, the gas pipes being distributed on the annular gas duct.

A grain dryer has an upper plenum in communication with a pair of heating columns. Each heating column has an inner boundary and an outer boundary being formed with a plurality of angled containment baffles configured to funnel grain down the heating column while allowing heated air to be drawn from the upper plenum through the grain. At least one fan takes a suction from the ductwork to draw heated air from the upper plenum through the heating column such that grain is exposed to heated air. The orientation of the containment baffles forming the inner boundary directs the flow of the heated air in a downward direction through an inner portion of a grain column between the inner boundary and the outer boundary, and the orientation of the containment baffles forming the outer boundary directs the heated air in an upwards direction in an outer portion of the grain column.

A liquification system for an organic waste management system includes a hopper that is oriented vertically such that organic waste added to the hopper is biased by gravity toward a bottom end of the hopper; a fixed grinding plate disposed at the bottom end of the hopper and including grinding elements for grinding and liquefying organic waste; an agitator that is disposed within the hopper and is movable relative to the grinding plate in a first rotational direction that moves organic waste downward toward and against the grinding plate and in a second rotational direction that moves organic waste upward toward a top end of the hopper; a motor configured to selectively move the agitator in the first and second rotational directions under control of the controller; and an outlet through the bottom end of the hopper through which liquified organic waste drains from the hopper.
