Capsule filling machines can be highly inefficient and wasteful if powder leaks during the filling process. This article will explore the common causes of powder leakage and provide simple solutions to keep your machine working at its best.

Powder leakage can result from a variety of mechanical and operational issues. These include capsule shell mismatch, inadequate vacuum suction, high powder viscosity, misalignment of filling modules, and incorrect dosage disk settings. Let’s take a closer look at each of these issues and discuss how to solve them effectively.

Detailed Analysis of Powder Leakage Causes and Solutions:

1. Capsule Shell Mismatch:

Problem: If the capsule shells are too small or too big for the machine, there will be gaps that cause the powder to leak.

Solution: Make sure you’re using capsule shells that match your machine’s specifications. If your machine has adjustable features, calibrate it to accommodate different shell sizes.

2. Inadequate Vacuum Suction:

Problem: If the vacuum suction isn’t strong enough, it won’t hold the powder, and it will spill out during the filling process.

Solution: Adjust the settings on your vacuum pump to increase the suction power. Regularly check and maintain your vacuum pump to ensure it’s working efficiently.

3. High Powder Viscosity:

Problem: Powders with high viscosity can stick to the machine’s modules, interrupting the flow and causing leaks.

Solution: Regularly clean the upper and lower modules to prevent powder buildup. Consider changing the powder formula to reduce its viscosity or using a different powder that’s better suited for your machine.

4. Misalignment of Modules:

Problem: If the upper and lower modules aren’t aligned properly, there will be gaps that allow powder to escape.

Solution: Use the adjustment rod to realign the modules so they’re perfectly aligned with no gaps. Regularly check the alignment of the modules as part of your machine maintenance routine.

5. Incorrect Dosage Disk Thickness:

Problem: If the dosage disk isn’t thick enough for the amount of powder you’re filling, it can overflow and cause leaks.

Solution: Adjust the amount of powder you’re filling to match the thickness of the dosage disk or replace the dosage disk with one that has the right thickness for your powder volume.

To prevent powder leakage, it’s important to understand your capsule filling machine’s specific capabilities and limitations. Implement a preventive maintenance schedule that includes regular checks and adjustments to catch these issues before they cause significant downtime or product loss.

Dealing with powder leakage in capsule filling machines requires a proactive approach to machine maintenance and operation. By understanding the common causes of leakage and implementing the solutions provided, you can improve the efficiency of your capsule filling process and maintain high-quality production standards.

Expert Tip:

Make sure all machine operators are trained on the specific requirements and settings for the capsules and powders used in your facility. Keeping detailed records of machine adjustments and maintenance can also help you track the effectiveness of the solutions you’ve implemented.
