Automatic Rotary Dry Syrup Powder Filling Machine
High-Speed Precision for Dry Suspensions
The Harsiddh Automatic Rotary Dry Syrup Powder Filler (Model HRDS Series) is a compact and versatile solution designed for Glass, PET, HDPE, and LDPE bottles. Specifically engineered for the pharmaceutical, food, and agrochemical industries, this machine delivers high-speed performance for dry syrup suspensions. With its monoblock-compatible design, it ensures uniform bulk density and consistent fill weights, achieving speeds of up to 80 to 120 bottles per minute.
Reliable Operational Workflow
The machine provides a continuous, high-efficiency path from empty bottle to precisely filled dry syrup container.
Sequence of Operation:
- In-feed: Bottles move from a turn table to the SS slat conveyor and are indexed into the filling zone via a star wheel.
- Vacuum Dosing: Powder is agitated in the hopper and drawn into the ports of the rotating powder wheel via vacuum.
- Positive Displacement: A doctor blade removes excess powder, and as the wheel indexes above the bottle, a sterile air flush discharges the precise dose.
- Assisted Filling: The rotary funnel follows the bottle movement, and the vibratory system ensures even the most difficult powders settle quickly.
- Clean Discharge: Filled bottles are moved out through the exit star wheel, leaving the neck and shoulder area free of dust and contaminants.

Frequently Asked Questions
How does the machine achieve precise dosing for dry syrup powders?
The machine operates on a Vacuum-Pressure Dosing Principle using a specialized rotary wheel.
Vacuum Suction: A vacuum is used to pull a precise volume of powder into the dosing wheel cavities from the overhead hopper.
Pressure Discharge: As the wheel rotates over the bottle, sterilized compressed air (or Nitrogen) discharges the powder directly into the container.
Accuracy: This method ensures a high filling accuracy of ±1% to 2%, even for fine powders that have poor flow characteristics.
Can the machine handle different bottle sizes and powder volumes?
Yes. The Harsiddh Rotary Powder Filler is designed for versatility in the pharmaceutical and nutraceutical industries. It can accommodate various glass and plastic (PET/HDPE) bottle shapes and sizes. The fill volume can be easily adjusted by changing the piston depth within the dosing wheel or by swapping the wheel for a different cavity size. "Quick-change" parts like star-wheels and back guides allow for efficient transitions between different bottle diameters.
How does the machine manage dust during the high-speed filling process?
To maintain a clean production environment and prevent cross-contamination, the machine includes several dust-control features:
Dust Extraction Hoods: Positioned at the filling point to capture airborne particles.
Funnel System: A specialized oscillating funnel system travels with the bottles to ensure all powder is directed into the bottle neck without wastage.
Enclosed Hopper: A stainless steel hopper with a motorized stirrer keeps the powder level consistent and contained.
What are the key cGMP and automation features of this model?
As a cGMP-compliant unit, the machine is built to the highest hygienic standards:
Material Integrity: All powder contact parts are made of SS 316L, and the exterior is polished SS 304 stainless steel.
Safety Sensors: Equipped with a "No Bottle – No Fill" system to prevent powder loss and mess if a container is missing from the star-wheel.
Advanced Control: Managed via a centralized PLC with a Touchscreen HMI, allowing operators to monitor production counts, adjust speeds, and view real-time diagnostic alerts for easy maintenance.
