摘要： A method is disclosed of controlling a plant for dehumidifying and/or drying plastic material in granular and/or micro-granular and/or powder and/or flake or similar form, this plant including a process fluid generator and at least one dehumidifying/drying hopper for feeding a respective user machine associated with the plant and including a melting device for melting the plastic material and a moulding device for moulding, in particular by injection moulding and/or blow moulding and/or compression moulding, the plastic material. The method of controlling includes the steps of detecting in the user machine a pressure (Ppwp) of the plastic material in melted state and modifying at least one process parameter (Dp) of the plant on the basis of the detected value of this pressure (Ppwp).

摘要： A thermal desorption device and method are disclosed in which: a container receives one or more objects that are ejected by the container and housed on a movable receiving shuttle that conveys the objects inside a thermal desorber; the container ejects an object, through magnets, on the shuttle that, through an electric or pneumatic actuator, conveys the object inside the cell of the thermal desorber; a cap, through an electric or pneumatic rotating means, closes and seals the object inside the cell; at the end of the thermal desorption time, the cap opens, through an electric or pneumatic rotating means, and the movable shuttle extracts the object from the cell and, with a rotating means, rotates the shuttle and unloads the desorbed object into a collecting tank; after the desorbed object is unloaded into the collecting tank, the movable shuttle returns to the initial position to receive a new object to be conveyed inside the thermal desorber.
