A material drying and cooling integrated machine, comprising a heating module, a drying module, a dust removal filter module, a temperature-lowering and dehumidifying module, and a cooling module. Dry hot air generated in the heating module can enter the drying module to dry materials; the temperature-lowering and dehumidifying module can conduct temperature lowering and dehumidification on air entering the interior thereof so as to form dry cold air, and the dry cold air can enter the cooling module to cool materials in the cooling module; the dry hot air enters the drying module to dry the materials in the drying module, then damp hot air is formed, and part of the damp hot air can be heated by the heating module again; the other part of the damp hot air can sequentially pass through the dust removal filter module and the temperature-lowering and dehumidifying module, and dry cold air can be formed.

Systems and processes for curing a wet coating of a coated substrate are disclosed. The system includes a ventilation system and a curing room configured to receive the coated substrate being displaced along a displacement axis and includes at least an upstream curing section and a downstream curing section. The upstream curing section includes an upstream catalytic infrared heating system for producing an upstream infrared radiation at an upstream radiation intensity to heat and partially cure the wet coating while the coated substrate is being displaced through the upstream curing section. On the other hand, the downstream curing section includes a downstream catalytic infrared heating system for producing a downstream infrared radiation at a downstream radiation intensity, being lower than the upstream radiation intensity, to further cure the wet coating while the coated substrate is being displaced through the downstream curing section for producing a cured coating.

An air curtain generating device includes: a plurality of pairs of an air jet unit and an air suction unit placed opposite each other on both sides in a lateral direction of an inlet/outlet of a drying chamber, the plurality of the pairs being aligned up and down, the air suction units sucking air ejected from the air jet units to generate an air curtain; a first air guide provided to the air jet units in an upper part of the inlet/outlet to guide air ejected from the air jet units in a direction inclined inward of the drying chamber relative to the lateral direction of the inlet/outlet; and a second air guide provided to the air jet units in a lower part of the inlet/outlet to guide air ejected from the air jet units in a direction inclined outward of the drying chamber relative to the lateral direction.

An oven may facilitate heating, curing, and/or drying processes for manufactured items, such as shoe parts, using multiple groups of infrared sources. Efficiencies of the oven are achieved through a deliberate airflow characteristic, which is accomplished with a configuration of apertures extending through a circulation plate. A higher concentration of apertures is formed in the circulation plate near a center zone relative to zones near an entrance and exit to the oven. Further, the shape of the apertures in the circulation plate aid in improved airflow within the oven.

A method and an apparatus are disclosed for analyzing an absorption filtering medium that filters volatile organic substances in a process gas in a dehumidification plant for dehumidifying polymer granules, with a fan that generates a flow of gas through the filtering medium, an analyzer for analyzing the concentration of total organic carbon, a sensor for detecting pressure downstream of the filtering medium, in which the state of saturation and/or the absorbent capacity and/or the deterioration over time of the filtering medium is determined by a comparison of the measured concentrations of the total organic carbon in the flow of gas upstream and downstream of the filtering medium.

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 round dryer for drying workpieces has a helically revolving workpiece passage in a work container and is provided with a heating device. The work container is closed at its upper side.

A dryer for a textile web includes a drying chamber having at least one air-permeable drum arranged in the drying chamber to rotate, wherein the drum includes an end face constituting an axially arranged suction side, the textile web is wrapable at least partially around the drum and heated drying air is flowable through the textile web. A hot gas source provides heated gas. A ventilator forms a suction draft via the suction side of the drum with drying air from inside of the drum and drying air that recirculates back into the drying chamber. At least one hot gas feeding ring encloses the suction draft and is configured to permit the hot gas from the hot gas source to flow essentially completely into the suction draft.

Air is taken out from a drying oven 1 for drying a coating film of a work piece 2, and the air is cooled such that each of at least part of moisture and at least part of a VOC which are contained in the air is condensed to be removed from the air. The air after the cooling is heated, and is returned into the drying oven 1. A heat pump 3 whose heat absorption source is the air taken out from the drying oven 1 and whose heat radiation source is the air after the cooling is provided. By using the heat pump 3, cooling and heating of the air are performed.
