Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, specifically to a drying device for modified plastic granules. Background Technology

[0002] Modified plastic granules require drying during processing to remove surface moisture and humidity, ensuring the quality of subsequent processing. Traditional drying equipment typically uses hot air circulation to dry the plastic granules, raising the air temperature through heating elements and using a fan to deliver the hot air into the drying chamber. However, existing drying equipment has certain limitations in practical use. For example, uneven hot air distribution may result in some granules not drying sufficiently, affecting the overall drying effect; at the same time, the material has poor flowability within the drying chamber, easily leading to accumulation and further reducing drying efficiency.

[0003] In addition, the existing equipment is inconvenient to clean and maintain. Especially after long-term operation, residues may accumulate on the inner wall of the drying chamber. If it is not cleaned in time, it will affect the working performance and service life of the equipment.

[0004] Based on the above, this utility model proposes a drying device for modified plastic granules, which can effectively solve the above problems. Utility Model Content
