An apparatus and a method is provided for continuously drying bulk goods, in particular wood fibers and/or wood chips, in a dryer, wherein the drying vapors are led to a dryer circuit, in which the drying vapors are indirectly heated via a heat-exchanger and are conducted to the dryer again.

A device for controlling the temperature of, and in particular for drying, objects, in particular vehicle bodies, having a housing which integrates a temperature-control chamber that includes at least one air outlet and at least one air inlet. The temperature-control chamber is assigned at least one heating unit in which it is possible to generate a hot primary gas flow and to which it is possible to supply, from the air outlet, air that is to be heated. The heating unit includes a heat exchanger device into which the hot primary gas can be guided and in which it is possible to heat air from the temperature-control chamber using hot primary gas, which air can be supplied, as heated recirculation air, in a circuit via the at least one air inlet back to the temperature-control chamber. The heating unit includes at least a first and a second flow outlet via which heated recirculation air leaves the heating unit.

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.

The softgel drying machine comprises a casing, an air channel, a drying chamber, an air return channel, a tumbler and an air-drying system. The casing comprises an air circulation chamber and an air generation chamber. The drying chamber comprises at least one air supply opening and at least one air returning plate. The air-drying system comprises at least one air blower fan, a dehumidification module and an air return cooling module. The air blower fan comprises an air blower inlet port, an air blower outlet port, a chiller and an air supply duct. The chiller is coupled to the air blower outlet port. The air return cooling module comprises an air return duct, an air return inlet port and an air return outlet port. The air return inlet port is airtightly coupled to the air return channel through the air return duct.
