In supplement manufacturing, the depositor is responsible for precisely filling capsules, tablets, or powders into containers. There is an inherent trade-off between the speed of the depositor and the accuracy of the fill weight. When machines run at higher speeds, the dwell time for each dose decreases, limiting the opportunity for the fill mechanism to settle and adjust. This can lead to greater weight variation, which compromises product consistency and can result in costly overfills or underfills.
How KorNutra Manages This Trade-Off
At KorNutra, we optimize high-speed lines by integrating advanced technology and real-time process controls. Our approach centers on three key strategies:
- Servo-Driven Filling Systems: Unlike traditional pneumatic or mechanical systems, servo-driven depositors allow for programmable acceleration and deceleration ramps. This means we can precisely control the filling stroke profile, maximizing speed during non-critical motion while slowing down at the point of product release to ensure weight accuracy.
- Dynamic Checkweighing with Feedback Loops: Every fill is instantly weighed by in-line checkweighers. A closed-loop feedback system continuously communicates with the depositor, making micro-adjustments to fill volumes automatically. If weights begin to drift, the system corrects itself without stopping the line.
- Tooling and Product Conditioning: We tailor the design of augers, nozzles, and hoppers to the specific flow characteristics of each formulation. Proper vibration and temperature control keep the bulk density consistent, which is critical for maintaining precision at high speeds.
By combining these elements, KorNutra’s high-speed lines achieve throughputs that meet demanding production schedules while consistently holding fill-weight tolerances far tighter than industry norms-demonstrating that speed and precision need not be mutually exclusive.
