    摘要： A heating apparatus for supplying heated air to a grain dryer or the like. The apparatus features a biomass furnace with a burn chamber for combustible biomass material, a chimney having a lower end in fluid communication with the burn chamber interior, and air ducting that has a fresh air inlet, an output end connected to the dryer, and directs heated exhaust air from the chimney to the dryer. An airflow control system is configured to both control airflow to the dryer through the air ducting, and control a temperature of said airflow by varying a ratio between the fresh ambient air and the heated exhaust air. The burn chamber has a chain gate with overbed and underbed circulation fans that generate airflow up through the chain grate, as well as tumbling air currents above the chain grate for thorough combustion and cleaner exhaust that won't contaminate the grain.

    摘要： The present disclosure relates to a towel maintenance device for storing and keeping a towel and for heating and drying the towel stored and kept therein. The towel maintenance device—provides a structure in which heated air flows in a first staying space formed in a heat transfer plate and heats the heat transfer plate, thereby allowing a textile product such as a towel and the like in contact with the heat transfer plate to be heated based on thermal conduction, and the heated air discharged through a communicating hole of the heat transfer plate is discharged while passing through the textile product such as a towel and the like or flows around the textile product such as a towel and the like, thereby allowing the product to be dried to be heated based on convection. The towel maintenance device according to the present disclosure enables entire objects to be dried to be rapidly heated and dried.

    摘要： The invention relates to a method for producing an anhydrous powder having a calcium nitrate content of between 92 and 99.9 weight %, a water content of between 0.1 and 8 weight %; and a particle size of between 0.05 and 1.5 mm, wherein the method comprises the step of subjecting a calcium nitrate solution having a water content of between 70 and 15 weight % and a calcium nitrate content of between 30 and 85 weight % to a drying step in an industrial turbo-dryer, resulting in the anhydrous calcium nitrate powder. The invention furthermore relates to such an anhydrous calcium nitrate powder and the use of an industrial turbo-dryer to produce such anhydrous calcium nitrate powder.

    摘要： This invention in the field of grain drying, along with other particulates, provides an apparatus which dehumidifies air, then heats the air to relative low drying temperatures (95-160 Deg. F.), provides the dehumidified, heated air as process air to a system which uses the airflow as a transport method to fluidize the particulate matter and move the mixed process air and particles through a process column for drying. Once a particle reaches a designed moisture level, its mass will have been reduced, and that effect plus the velocity of the process air in the column will float the dried particle up and out of the column for further handling.

    摘要： Method and apparatus for hot air drying granular polymeric resin material records heating air temperature at a heating air outlet, computes air flow rate through a hopper, maintains desired throughput of granular material being dried in the hopper until heating air outlet temperature is stable, and thereafter maintains air flow rate through the hopper and monitors that air flow rate to adjust the air flow rate to maintain a computed preferred air flow rate through the heating hopper.
