Claim:
1. A device for air-based solar thermal generation of process heat in order to assist drying processes in a temperature range of from 300° C. to 700° C., having the following features: a) at least one elongated collector in the form of a mirror system, a first elongated collector forming a first solar field of concentrated solar radiation on a first chamber of a first size, a second elongated collector forming a second solar field of concentrated solar radiation of a second chamber of a second size, the first chamber being larger than the second chamber, b) at least three air receivers having a different radiation concentration are arranged in series in sections, the at least three air receivers having the configuration of an air channel in which at least one linearly structured heat exchanger comprising ceramic is arranged, wherein the at least three air receivers are in an angled arrangement and heated by more than one solar field, c) the heat exchanger is insulated against radiant heat emission by an insulating cladding, d) solar-thermally generated hot air is added as a function of the solar-thermally generated hot air's respective temperature as a partial flow of process air generated by other systems.
