How To Adjust The Filling Dose of Automatic Capsule Filling Machine

Steps to Adjust Filling Weight

1. Adjust Filling Rod Height (Coarse Adjustment)

• Principle: The depth of the filling rod determines the filling weight—deeper insertion increases weight.

• Operation:

• Clockwise: Rod moves downward → Increase filling weight.

• Counterclockwise: Rod moves upward → Decrease filling weight.

1. Locate the adjustment screw or handle (position varies by model; refer to the manual).

2. Loosen the locking nut and rotate the screw:

3. Tighten the nut after initial adjustment and test manually (do not power on).

2. Adjust Dosing Disc Thickness (Fine Adjustment)

• Applicability: Used when rod adjustment is insufficient or weight variation is large.

• Operation:

1. Remove the dosing disc and replace shims (typically 0.1mm, 0.2mm, etc.).

2. Thicker shims → Larger filling space → Increase weight; thinner shims reduce weight.

3. Adjust Filling Speed (Auxiliary Adjustment)

• Some models allow speed or vibration frequency adjustments (low speed for poor-flow materials).

4. Test Run & Weighing

1. Manually fill 10–20 capsules and weigh each.

2. Calculate average weight. If outside target:

• Underweight: Slightly lower the rod or add shim thickness.

• Overweight: Adjust inversely.

3. Repeat until weight stabilizes within ±5% of target (e.g., 285–315mg for 300mg target).

By systematically following these steps, capsule filling dose can meet specifications. If issues persist, consult the Migrand’s technical support.
