Abstract
The present disclosure relates to a method and a device for cooling a solid, in particular a hygroscopic bulk material, in a more energy-efficient manner. For this purpose, an air flow is, if needed, cooled and/or dehumidified and/or subsequently heated in order to reduce the relative humidity of the air flow. The cooling air flow conditioned in this manner is then used in a contact device for cooling the solid, and a heated exhaust air flow is drawn from the contact device. According to the invention, a part of the exhaust air flow is mixed with the air flow in order to pre-heat the air flow and thus reduce the relative humidity of the air flow. In addition, a second part of the exhaust air flow can be mixed with feed air and used in a separate second contact device in order to pre-cool the solid.
