Abstract: A modified dryer operates on a different principle from that used by the prior torrefaction plants. The subject invention utilizes thermal conduction to torrefy the biomass in a vibratory reactor in which a heated solid unperforated plate is sealed in the reactor to separate the biomass above from the gas used to heat the plate below. This permits using inert flue gas to heat the reactor which in turn permits the use of a cool air damping system to prevent thermal runaway. Also syngas evolved from the process is utilized to power a gas engine, the exhaust output of which is recirculated to heat the reactor plate. When the gas engine is coupled to an electric generator, waste energy is recovered for use in other parts of the plant or exported elsewhere.

Abstract: What is described is a process and an installation for drying articles, in particular painted vehicle bodies, in which the articles are moved through a drying zone in which they are hardened in an inert-gas atmosphere. Inert gas is taken from the drying zone constantly or intermittently and is first of all conducted along a first face which is at a first temperature at which higher-boiling contaminants condense out. The condensate that forms in the process is discharged. After that, the inert gas which has been pre-cleaned in this way is conducted along at least one second face which is at a lower temperature than the first face. Lower-boiling contaminants are precipitated at this point. These condensates, too, are then discharged. This process and installation work more favourably, energy-wise, and with higher cleaning efficiency than known processes and installations of a similar type.

The temperatures can be adjusted by adjusting, with the aid of valves (8), the pressure of the steam, which heats the drying air that is fed into the various zones (9a-9e), on the basis of the temperatures measured by the sensors (23) for the various zones and of the basis weight and moisture measurements carried out on the web (2) that goes into the box (1) and comes out of the box.

Abstract: The present invention is a method of drying clothing. The method of drying clothing involves providing a dryer, preferably a coin-operated clothes dryer. The dryer contains a heat source in thermal communication with the dryer. Next, a user inserts clothes into the dryer and initiates a drying cycle to reduce the overall moisture within the clothes. To initiate a drying cycle, the user purchases a predetermined period of time that is at least one block of time. The dryer is turned on and the heat source is then operated at a first drying temperature, preferably 160° F., while a sensor detects the level of moisture within the clothes. Once the level of moisture within the clothes is below a predetermined level, the heat source is lowered to a second operating temperature, preferably 100° F. This method of reducing heat conserves energy to operate the dryer and helps avoid over-drying of clothes.
