Granules loss-in-weight feeder MedLine® TrueFeed series

for plastic pelletsgravimetricvolumetric

Overview
Optimize medical polymer feeding with the MedLine® TrueFeed gravimetric feeder. Designed for cleanroom-ready production, the unit uses continuous loss-in-weight metering with closed-loop speed control to deliver precise, consistent additive and color dosing for injection molding, extrusion and blow molding. The MedLine® TrueFeed is calibrated to ISO medical standards and finished in RAL 9003 for hygienic environments. The intuitive bilingual touchscreen simplifies operation and reduces setup time.

Features

• Tool-free material and color changes for fast maintenance and reduced downtime.
• Continuous loss-in-weight metering with closed-loop speed control for accurate feeding rates.
• MedLine calibration to ISO medical standards and RAL 9003 paint finish for cleanroom compatibility.
• Bilingual, user-friendly touchscreen common to all models for streamlined operation.
• Dispensing cylinder driven by a stepper motor for consistent, non-pulsing feed and superior dosing accuracy compared with auger systems.

Frequently Asked Questions

• How does this reduce material costs? The steady, non-pulsing dispensing cylinder minimizes overfeed and waste, improving material yield.
• How does it improve productivity? Quick material and color changeover plus pre-calibrated MedLine settings reduce machine downtime versus volumetric feeders.
• How accurate is the dosing? The combination of loss-in-weight measurement and stepper-driven dispensing cylinder provides highly repeatable, precise dosing for consistent product quality.

Options

• Compressed air loading lid — assists handling of granular pellets.
• Throat adapters — multiple adapters available; standard adapter indicated as 76 mm diameter inlet and 45 mm square outlet.
• Compressed-air vacuum loading lid — improves pickup for dusty/granular materials and includes a filter to trap fines.
• Water-cooled throat adapter — isolates temperature when introducing temperature-sensitive additives into hot material.
• Dispense cylinder — non-pulsing cylinders in several sizes for different accuracy requirements; quick-change design for cleaning.
• Alarms (visual and/or audible) — optional low material level alerts.
