Abstract
A deodorization method and apparatus are disclosed to eliminate, reduce or correct the odour of incoherent plastics, i.e. in the form of granules and/or microgranules and/or powder and/or flakes or the like, with a container of the incoherent plastics, an actuator for generating a process gas flow from a gas inlet to a gas outlet of said container, an olfactory sensor arranged to detect odorous emissions in the process gas exiting from said container, a controller configured to control at least one parameter of the process gas on the basis of an odour intensity measured by said olfactory sensor, with the aim of eliminating the substances that cause undesired odours from the incoherent plastics that is usable in a transformation process to make an end product.
Claims4
A deodorization method, to eliminate, reduce or correct an odor of an incoherent plastic material, the method comprising the steps of:
- generating a flow of a heated process gas through the incoherent plastic material to extract odorous emissions;
- detecting the odorous emissions in the heated process gas that has passed through the incoherent plastic material by means of an outlet olfactory sensor;
- and
- controlling at least one process parameter on a basis of the detected odorous emissions.
