<p>PURPOSE:To provide a heat recovering device, which reduces the usage of freezing medium such as liquid nitrogen or the like necessary for low temperature treatment or the amount of heat energy necessary for high temperature heat treatment, by a method wherein the energy, which is wasted heretofore of a treated product, is efficiently recovered in a heat treating device, with which low temperature or high temperature heat treatment is applied to a matter to be heat-treated. CONSTITUTION:In a heat insulating tunnel 4, two-way conveyers 2a and 2b, which are made of meshy or perforated belt 2, for conveying normal temperature raw material and high temperature or low temperature treated material are provided in parallel with each other. Further, at least one fan 7 is provided for sending air in order to heat-exchange between the raw material Ms and the treated material Mp, between which temperature difference is present.</p> |
