Drying and sampling device for EPP foaming process

The utility model discloses a drying and sampling device in an EPP (Expanded Polypropylene) foaming process, which is characterized in that after directly sampling through a foaming main pipeline, drying through hot air, fully dehumidifying particles, intensively sucking the particles into a sampler through a fan, and then timely confirming the density change in the foaming process in a free falling body accumulation mode. Therefore, the accuracy of density measurement is greatly improved, the fluctuation condition of the density of a one-time foaming product is reduced, and the foaming density of the EPP can be controlled within the fluctuation range of 4-5g/L. 本实用新型公开了一种EPP发泡过程烘干取样装置，通过发泡主管道直接取样后，经热风干燥，将粒子充分除湿后，经风机将粒子集中吸到取样器中，再通过自由落体堆积的方式，可及时确认发泡过程中的密度变化，从而极大程度上提高密度测量的准确性，减少一次发泡产品密度的波动情况发生，可以将EPP发泡密度控制在4-5g/L的波动区间。
