Drying hopper MedLine® ResinWorks series

for plastic pelletscleaning systemwith dryer

Overview
MedLine® ResinWorks is a centralized resin drying and pre-conditioning system designed to consolidate resin handling away from processing machines. The system mounts multiple mass‑flow stainless steel hoppers on pre-plumbed, pre-wired sleds connected to a dehumidifying dryer to deliver pre-dried, pre-conditioned material rapidly and cleanly.

Features

• Flexible supply: any resin to any machine on demand.
• Rapid material changes: pre-dried, pre-blended batches ready in about ten minutes.
• Clean processing area: drying and blending equipment removed from molding stations.
• Small-batch conveying: precise transfer from dryer or blender to processing machines.
• Automatic line purging after each cycle to avoid cross-contamination.
• Reduces labor, energy, material waste and inventory overhead.

Key Product Elements

• Integrated supply and return air manifolds simplify installation of conveying lines to each hopper.
• Mass‑flow stainless steel drying hoppers with oversized clean-out doors, removable cones and full-length sight glass for level indication.
• Electrical access relocated to the sled front to minimize clearance and floor space requirements.
• Fully automatic airflow balancing valve removes the need for manual adjustments at individual hoppers.

Frequently Asked Questions (selected)

• Quick clean hoppers – Large stainless clean-out doors and removable cones enable fast, validated cleaning and material changeover for medical/cleanroom environments.
• Superior mass flow – Hopper design ensures uniform exposure to dry air and heat; eliminates hang-up points for consistent drying.
• Long life tube heaters – Compact tube heaters at each hopper inlet provide accurate temperature control with minimal energy loss.

Options

• Adjustable Purge Valve – Controls material flow between source and destination; 360° rotating discharge for complete line purge.
• Slide Gate – Prevents leakage when no purge valve or distribution box is fitted.
• Multiple Sled Connection Kit – Connects sleds for integrated supply, return and conveying manifolds; kit required per junction.
• Hopper Discharge Drain Port – Facilitates draining and cleaning of hoppers.
• Temperature Setback RTD – Automatically reduces drying temperature to standby when throughput drops.
• Communications – Modbus and DeviceNet options for system integration and monitoring.
