Automatic Rotary Dry Syrup Powder Filling Machine

High-Speed Precision for Dry Suspensions & Sterile Formulations

In the modern pharmaceutical, nutraceutical, and chemical manufacturing sectors, precision is the cornerstone of product integrity. The Automatic Rotary Dry Syrup Powder Filling Machine manufactured by Harsiddh Unimach Pvt. Ltd. represents the pinnacle of high-speed, volumetric dosing technology. Engineered specifically to handle free-flowing and non-free-flowing dry powders, this advanced equipment delivers an uncompromising level of accuracy, speed, and hygienic operation required for sensitive dry suspension products.

Designed with a compact footprint and high-end automation, our rotary powder filling system seamlessly accommodates a diverse range of container materials, including Glass, PET, HDPE, and LDPE bottles. Whether you are running high-volume pharmaceutical dry syrups, pediatric antibiotic suspensions, or specialized food and agrochemical powders, this system ensures uniform bulk density and consistent fill weights across every batch. With the capability to achieve throughput speeds ranging from 80 to 120 bottles per minute (depending on container size and powder characteristics), it is the ultimate asset for processing lines where efficiency and regulatory compliance are non-negotiable.

Key Industry Applications

The versatility of our engineering makes this rotary dry syrup powder filler an indispensable asset across multiple strict regulatory industries:

• Pharmaceuticals: Perfect for oral dry suspensions, antibiotic powders, and pediatric syrup formulations.
• Nutraceuticals & Dietary Supplements: Ideal for protein powders, vitamin blends, and meal replacement dry bases.
• Food Processing: Suitable for fine spices, baking ingredients, drink mixes, and milk powders.
• Agrochemicals: Designed to handle chemical powder formulas requiring strict dosage control and zero environmental leakage.

Innovative Technology & Advanced Engineering Features

At Harsiddh Unimach Pvt. Ltd., we understand that powder filling presents unique challenges—including dust control, variation in bulk density, and container neck contamination. Our Automatic Rotary Dry Syrup Powder Filling Machine addresses these issues through a series of proprietary design choices:

1. Monoblock-Compatible Design

The machine architecture is built to easily integrate with upstream and downstream equipment. It can be paired directly with automatic bottle washing machines, air jet cleaning systems, and rotary capping units to form a fully automated, continuous monoblock production line.

2. Advanced Vacuum-Pressure Dosing System

Unlike traditional auger systems that can compress and degrade sensitive powder particles, our system utilizes a sophisticated rotary powder wheel equipped with vacuum dosing ports. Powder is gently drawn into the wheel cavities via precise vacuum levels and discharged cleanly using a controlled sterile air flush. This eliminates friction, reduces product degradation, and ensures weight variations remain well within strict international pharmacopeia limits.

3. Comprehensive Dust Management & Hygiene

Dry syrup filling can generate airborne particles that threaten cleanroom standards and compromise bottle sealing zones. Our machine features a built-in dust extraction hood positioned at the filling zone to capture ambient particulates. Additionally, the mechanical components are enclosed in premium Stainless Steel (SS 304/SS 316L) to meet rigorous cGMP manufacturing standards.

4. Smart Control Integration (PLC & HMI)

Equipped with an intuitive touchscreen Human-Machine Interface (HMI) and a programmable logic controller (PLC), operators can manage filling speeds, vacuum durations, and air flush intervals with exceptional ease. Built-in “No Bottle – No Fill” sensors prevent powder wastage and line messes by halting the dosing cycle if a container is missing from the conveyor line.

Reliable Operational Workflow: Step-by-Step

The machine provides a continuous, highly efficient path from empty bottle to precisely filled dry syrup container, minimizing human intervention and maximizing production safety.

[In-Feed & Conveying] ➔ [Star Wheel Indexing] ➔ [Vacuum Dosing Wheel] ➔ [Assisted Funnel Filling] ➔ [Clean Out-Feed]

Step 1: Automated In-feed & Conveying

Empty bottles arrive from the upstream process or an automated turn table onto a heavy-duty, variable-speed Stainless Steel (SS) slat conveyor. The conveyor guides the containers smoothly toward the filling zone, preventing tipping or scuffing of lightweight PET/HDPE bottles.

Step 2: Precision Star Wheel Indexing

As the bottles approach the main filling area, an engineered in-feed star wheel captures and indexes them at exact, synchronized intervals. This mechanical synchronization ensures that each container aligns perfectly underneath the rotating filling funnels, eliminating product spillage.

Step 3: Vacuum Powder Dosing & Positive Displacement

Simultaneously, the dry syrup powder is continuously agitated within the main hopper to maintain a uniform bulk density. The vacuum system draws a precise volume of powder into the ports of the rotating powder wheel. A precision-engineered doctor blade cleanly removes any excess powder from the wheel surface to guarantee an exact dose. As the wheel rotates directly above the indexed bottle, a sterile air flush provides positive displacement, cleanly discharging the entire powder dose downward.

Step 4: Assisted Filling & Vibratory Settling

To manage difficult, low-density, or fine powders that tend to bridge or stick, the machine utilizes a rotary funnel system that moves in absolute harmony with the bottles. Accompanying this is a specialized mechanical or ultrasonic vibratory system. This vibration gently agitates the bottles during the filling window, encouraging the powder to settle quickly and completely into the body of the container.

Step 5: Clean Discharge & Neck Integrity

Once filled, the bottles are guided away from the dosing zone by an exit star wheel back onto the main conveyor line. Because of our targeted funnel design and dust extraction capabilities, the neck and shoulder areas of the bottles remain completely free of dust and powder contaminants. This clean discharge is critical for ensuring a perfect, airtight seal during the subsequent capping and induction sealing phases.
