Analysis apparatus , comprising: - a container which defines a containing volume for incoherent material, said containing volume being less than 50 dm 3 , said container comprising a container axis which, in a position of use of the analysis apparatus, is arranged vertically; - a material inlet arranged to introduce material into an upper zone of said containing volume; - a material outlet arranged to extract material from a lower zone of said containing volume; - a gas path of a flow of a process gas intended to process incoherent material in said containing volume; - a compressed gas dehumidifier , i.e. a dehumidifier configured to exploit the dehumidification effect of a gas by compressing and subsequently expanding the gas, arranged in said gas path to dehumidify the process gas; - a heater arranged in said gas path to heat the process gas to a temperature higher than 40°C; - a conduit arranged in said containing volume to transport said flow of a process gas and provided with a diffuser arranged to diffuse the process gas in said containing volume so that said diffuser can be surrounded by the incoherent material contained in said containing volume; - a gas outlet (OUT) for extracting process gas from a zone of said containing volume arranged above said diffuser ; - an odour sensor arranged to detect odorous features of the process gas present in said containing volume and/or of the process gas extracted from said containing volume; - a calculation unit configured to perform a comparison between data detected by said odour sensor and stored data and to characterize the incoherent material on the basis of said comparison. - a container which defines a containing volume for incoherent material, said containing volume being less than 50 dm 3 , said container comprising a container axis which, in a position of use of the analysis apparatus, is arranged vertically; - a material inlet arranged to introduce material into an upper zone of said containing volume; - a material outlet arranged to extract material from a lower zone of said containing volume; - a gas path of a flow of a process gas intended to process incoherent material in said containing volume; - a compressed gas dehumidifier , i.e. a dehumidifier configured to exploit the dehumidification effect of a gas by compressing and subsequently expanding the gas, arranged in said gas path to dehumidify the process gas; - a heater arranged in said gas path to heat the process gas to a temperature higher than 40°C; - a conduit arranged in said containing volume to transport said flow of a process gas and provided with a diffuser arranged to diffuse the process gas in said containing volume so that said diffuser can be surrounded by the incoherent material contained in said containing volume; - a gas outlet (OUT) for extracting process gas from a zone of said containing volume arranged above said diffuser ; - an odour sensor arranged to detect odorous features of the process gas present in said containing volume and/or of the process gas extracted from said containing volume; - a calculation unit configured to perform a comparison between data detected by said odour sensor and stored data and to characterize the incoherent material on the basis of said comparison. <EOS>
