A1

A method of and an apparatus for drying pulverized bodies are provided which have an effect in dispersing the pulverized bodies in a drier with the advantages of a conventional flush drier provided, and which are capable of lengthening the residence time of pulverized bodies and improving the dried condition of pulverized bodies. The pulverized body drying method is constituted by the steps of forming a turning ascending current of a heated gas in a cylindrical container having inner spaces which are concentric in an arbitrary horizontal cross section, and dispersing pulverized bodies in a floated state in the turning ascending current to dry them. The pulverized body drying apparatus is provided with a cylindrical container having inner spaces which are concentric in an arbitrary horizontal cross section, pulverized body and heated gas introduction pipe joined to a lower portion of the cylindrical container, a swirl mechanism adapted to turn a heated gas, which is supplied from the introduction pipe, into a turning ascending current in the cylindrical container, and a pulverized body and heated gas discharge pipe joined to an upper portion of the cylindrical container.
