摘要： 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.

摘要： An improved mixed flow grain dryer is presented having a grain column with upper, middle and lower drying sections. The system includes a set of plenums and ducts configured to move air through the middle and lower drying sections at one or more lower temperatures, recover the air moved through the middle and lower drying sections, and move the recovered air through the upper drying section at a higher temperature. The system is configured to move grain through the upper drying section, then through the middle drying section, then through the lower drying section, while also: moving air of one or more lower temperatures through lower drying section and middle drying section, combining air moved through lower drying section and middle drying section, and moving the combined air through the upper drying section at a higher temperature.

摘要： Described is a method and apparatus for drying organic material using the energy contained in the organic material to be dried to drive the drying process. The organic material could be sewage sludge, food scraps, manure, wood, bagasse etc. The latent heat of evaporation is recovered through the use of a heat pump mechanism. This allows for the retention of a majority of the heat within the system, allowing optimal drying conditions to be maintained throughout the drying process.

摘要： A dryer (100), comprising a dryer chamber (101) coupled to a closed loop gas-circulating system for circulating gas through the dryer chamber (101); wherein the closed loop gas-circulating system recirculates the gas and comprises: a compressor (113) coupled to receive return gas from the dryer chamber (101) and to compress the return gas to provide compressed gas; a separator (109) sitting in the gas-circulating system for draining condensate from the gas; and a gas discharger (103; 104) coupled to receive compressed gas from the compressor (113) and to discharge the compressed gas through a discharger exit (118). The separator sits in the closed loop gas-circulating system downstream of the compressor to receive compressed gas and upstream of the gas discharger (103;104). Thereby drying efficacy is improved and is advantageous at relatively low drying temperatures such as below 40 degrees Celsius. There is also provided a door for a dryer, a method of operating a dryer and a method of drying, such as a method of drying pharmaceutical substances, compounds, ingredients or products.

摘要： An improved grain dryer is presented having a mixed-flow heating section having a plurality of inlet ducts connected to the plenum that facilitate air flow into the grain column from the heated and pressurized heat plenum, and a plurality of exhaust ducts connected to openings in the exterior wall that facilitate air flow out of the grain column. A tempering section is positioned below the heating section and includes solid walls that reduce air flow through the grain column. A cooling section is positioned below the tempering section and includes perforated walls that facilitate air flow through the grain column and into the plenum. In use, heated air is forced outward through the mixed-flow heating section heating and drying the grain and air is pulled through the cross-flow cooling section cooling the grain. Air pulled through the cross-flow cooling section is recycled into the mixed-flow heating section thereby recycling heat.

摘要： Drying of recycled abrasive that can be recycled separated or as a part of the full recycling system. Sorted and meshed wet recycled abrasive is kept in a hopper for wet recycled abrasive, it is continuously delivered using a screw feeder into a drying chamber on a vibration mesh. Air is blown in the chamber, using an air flow generator, under a vibration mesh. The recycled abrasive is moved and lifted on the mesh using air flow and mesh vibration, this provides for clots of recycled abrasive to break down to particles of recycled abrasive and abrasive mixes and dries.
