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.
Claims16
Deodorization apparatus to eliminate, reduce or correct an odor of an incoherent plastic material, the apparatus including:
- at least one container with at least one material inlet for introducing the incoherent plastic material;
- at least one material outlet for extracting the incoherent plastic material;
- at least one gas inlet for introducing a process gas;
- at least one gas outlet for extracting the process gas;
- an actuator for generating a process gas flow which enters the gas inlet and exits from the gas outlet;
- an outlet olfactory sensor arranged at the gas outlet to detect odorous emissions within the process gas exiting from the container after processing the incoherent plastic material in the container;
- and
- a controller configured to control the apparatus on a basis of signals provided by the outlet olfactory sensor, wherein:
- when the odorous emissions are detected by the outlet olfactory sensor, the controller is configured to control the actuator to remove the odorous emissions.
