METHOD FOR PROCESSING POLYMER GRANULATED MATERIAL AND INSTALLATION OPERATING IN ACCORDANCE WITH THIS METHOD Russian patent published in 2024 - IPC F26B3/06 F26B20/00 F26B21/04 F26B25/22 

FIELD: polymer granular materials.

SUBSTANCE: invention relates to a method for processing a polymeric granular material, including a drying step for the granular material, a transformation step by moulding or extrusion, and a processing plant. The method for processing polymer granular material (2) includes the steps of heating and drying the granulated polymer material in a drying hopper (10) using a drying gas, discharging a part of the granulated polymer material into an extruder (101), inside which the granular polymer material is brought to a molten or semi-molten state, and transported through the extruder by means of a rotating screw (104) to be injected into a mould (102) or passed through an extrusion die. The process involves measuring a control parameter that is correlated with the rotation of the screw inside the extruder and adjusting the flow rate of the drying gas based on the control parameter.

EFFECT: stability of the drying process of polymer granular material by optimizing the energy efficiency of the process and its reliability, as well as increasing productivity while ensuring quality and reducing the formation of processing waste.
