METHOD AND DEVICE FOR TREATING, PROCESSING AND/OR RECYCLING OF THERMOPLASTIC MATERIALS

What is disclosed is a method of processing and/or recycling materials, especially thermoplastic materials, wherein the material is agitated and mixed m a receiving vessel (1), especially a cutting compressor or a preconditioning unit (PCU), and optionally also heated, committed and/or softened, wherein the material in the receiving vessel (1) remains in the form of pieces or particles and unmoltenthroughout, and-wherein the material in piece or particle form being agitated within the receiving vessel is subjected to inline spectroscopic and/or spectrometric analysis and/or measurement wherein die measurements ascertained in tins way are employed to obtain information about the material being analysed in each case, especially quantitative and/or qualitative indices of the respective material. Likewise disclosed is an apparatus comprising-at least one receiving vessel (1), especially a cutting compressor, having a mixing and/or comminuting device for the material, -at least one spectroscopic and/or spectroscopic and/or measuring apparatus (10) for inline analysis of portions of the material in piece or particle form being agitated within the receiving vessel (1), which is designed to emit a physical Stimulus, especially electromagnetic radiation, for excitation of the rotating material in piece or particle form and-to detect the measurement Signals that arise in reaction to the Stimulus, especially characteristic spectra of the electromagnetic radiation scattered on the material analysed, preferably by spectrometric means, and-a Processing and control unit (40) which is in data communication with the measurement apparatus (10) and is designed-to actuate the measurement apparatus (10), to emit the physical Stimulus, especially electromagnetic radiation, and to detect the resultant measurement Signals and to hold the measurements ascertained in this way available and-optionally, on the basis of the measurements ascertained, to derive and hold available Information concerning the material analysed in each case, especially quantitative and/or qualitative indices of the respective material.
