Automatic Visual Vial Dry Powder Inspection Machine
Critical Inspection for Dry Powder Injectables
The Harsiddh Automatic Visual Vial Dry Powder Inspection Machine (HINS-240) is an essential quality control unit for sterile powder filling lines. Unlike liquid inspection, dry powder requires specialized handling to identify clumping, under-fills, or contaminants within the powder cake. By utilizing a motorized bifurcated conveyor system, this machine delivers vials to multiple operator stations, where they are scrutinized through magnifying lenses under optimized lighting before being released for labeling.
Reliable Operational Workflow
The machine streamlines the final quality check before secondary packaging:
- Feeding & Bifurcation: Vials arrive from the capping machine via a central conveyor and are automatically split into two adjoining tracks.
- Agitation & Rotation: As vials move along the rollers, they rotate continuously, allowing operators to see all sides of the glass and the surface of the powder.
- Visual Examination: Operators inspect the vials against a high-contrast background to verify the integrity of the aluminum seal and the purity of the dry powder.
- Instant Rejection: Upon spotting a defect—such as a cracked neck or a foreign fiber—the operator uses a pneumatic switch to remove the vial from the main track.
- Discharge: Accepted vials are merged back onto the central conveyor and transferred directly to the labeling machine.

Frequently Asked Questions
How does the machine ensure a 360-degree thorough inspection?
To ensure no defect goes unnoticed, the machine utilizes a vial rotation mechanism. As vials move along the conveyor, they are picked up by a specialized indexing system that rotates each vial rapidly on its own axis. This high-speed spinning agitates the powder, making any heavy foreign particles or glass fragments more visible to the inspector as the vial slows down in front of the illuminated background.
What kind of lighting and visual aids are used to assist the operator?
The Harsiddh inspection machine is equipped with a high-contrast illumination system, usually consisting of:
Black and White Backgrounds: To help detect both light and dark-colored particulate matter.
Flicker-Free LED Lighting: Provides consistent, high-intensity light that reduces operator eye fatigue while highlighting cracks or impurities.
Magnifying Lens (Optional): Some models include a large magnifying glass to provide a clearer view of the vial's interior and seal integrity.
What is the production capacity and vial size range?
This machine is designed for high-speed pharmaceutical lines:
Output: Depending on the model and the operator's efficiency, it can inspect 60 to 120 vials per minute.
Vial Range: It is highly versatile and can accommodate glass vials ranging from 2ml to 100ml with simple adjustments to the conveyor guides and rotation rollers.
What are the key cGMP and safety features of this machine?
As a cGMP-compliant unit built for sterile environments:
Material Integrity: The exterior frame is constructed from polished SS 304, ensuring it is easy to clean and corrosion-resistant.
Reject System: Many models feature a manual or pneumatic rejection station, allowing the operator to segregate "rejected" vials into a separate bin without stopping the entire production line.
Safe Operation: The machine features a compact, ergonomic design that minimizes manual handling, reducing the risk of vial breakage or contamination.
