Essential features of Rapid Mixer Granulator.

Written by ChemiplantMay 23, 2024

The Rapid Mixer Granulator (RMG) by Chemiplant is an indispensable machine for the homogeneous mixing and granulation of powders in various industries, including pharmaceuticals, chemicals, cosmetics, and food processing. This high-performance equipment is designed for efficient dry mixing and wet granulation, ensuring optimal product quality and consistency.

The Rapid Mixer Granulator from Chemiplant is designed to deliver just that – efficient and thorough mixing and granulation in a compact, user-friendly design.

At the heart of this machine is the unique three-arm mixing impeller that enables both dry mixing and wet granulation within the same cylindrical mixing drum. The impeller’s rotating action first blends the dry powder ingredients. Then a liquid binder solution can be sprayed directly into the powder bed through precision nozzles. As the impeller continues mixing, the chopper blades work to disperse the binder evenly for ideal granulation.

Key Features and Benefits:

  • High-Shear Mixing
    The high-shear mixer capabilities of the RMG make it ideal for creating emulsions, suspensions, lyosols, and granular products. This feature is essential for processes like emulsification, homogenization, particle size reduction, and dispersion.
  • Efficient Mixing Process
    The RMG performs dry mixing as the first step, using a bottom drive rotating impeller. Once the dry ingredients are adequately mixed, a binder is introduced either as a solution or in dry form. The mixing impeller and chopper blade work together to ensure quick and even distribution of the binder.
  • Quick Batch Times
    With its efficient mixing action and ability to blend and granulate in one step, the Rapid Mixer Granulator dramatically reduces processing times compared to conventional methods.
  • Modular and Versatile
    The machine’s modular design includes chopper blades for optimal results and a spray nozzle with a peristaltic pump for binder addition. The RMG also features a jacket for cold/hot water circulation and PLC-based control with recipe administration and visualization.
  • Flexible Capacities
    Available in various models ranging from 25 to 1250 liters, the RMG caters to different production scales, making it suitable for both small-scale and large-scale operations.
  • Advanced Sealing and Cleaning
    With air purge sealing for the main shaft and a unique design that allows the impeller to lift for easy cleaning, the RMG ensures hygiene and minimal cross-contamination. The machine also features integrated WIP (Wash-In-Place) and CIP (Clean-In-Place) systems, enhancing cleaning efficiency.
  • Safety and Compliance
    Chemiplant’s RMG adheres to GMP standards and offers flame-proof and SS 316 construction options. The machine’s enclosed moving parts ensure maximum safety during operation.

Conclusion:


Chemiplant’s Rapid Mixer Granulator is a versatile machine essential for industries requiring efficient mixing and granulation processes. Its advanced features, coupled with user-friendly design and safety compliance, make it a top choice for enhancing productivity and product quality. Whether for pharmaceuticals, chemicals, cosmetics, or food processing, the RMG is designed to meet diverse industry needs with precision and efficiency.

5 Common Mistakes to Avoid When Using a Rapid Mixer Granulator

Written by ChemiplantApril 8, 2024

The Rapid Mixer Granulator performs dry mixing & wet granulating by basic design of the special three arm of the mixing impeller and sequences of the mixing process in the cylindrical mixing drum with a rounded connection to the base plate, achieving another special effect. Dry mixing is the first step of the process. Once the products are mixed by the bottom drive rotating tool (impeller), a binder is added to the product. The binder can be sprayed in as part of a binding solution or it can be added in dry form. After this Mixing process, the spraying process occurs through one or more spray nozzles, and by mixing action of the main mixing tool (impeller) and the chopper blade it is quickly dispersed into the product.

Rapid Mixer Granulator Machine is used for the homogeneous mixing of granulation powder used for the production of tablets. It is also used for the process of wet mixing & fast drying. humidifying of the powder in Chemical, Cosmetic, Food, Plastic, Pharmaceutical, General Mixing Industries, etc.

Mistakes to Avoid When Using a Rapid Mixer Granulator:

1. Poor Impeller Blade Design: Proper impeller blade design is essential for efficient mixing. Using blades that are too tiny or incorrectly positioned might cause uneven mixing and granulation. Make sure that the impeller blades are designed to lift and push the material properly, promoting good circulation even at low speeds.

2. Inadequate Chopper Speed: The speed of the chopper blades impacts the size of the granules. Running the chopper at the wrong speeds can result in large or undersized grains. To achieve the best results, set the chopper speed to match the required granule size.

3. Improper Wet Milling Procedure: Wet milling is an important phase in the granulation process. Using a particle size reduction milling machine with improper screen apertures can result in uneven granule sizes. It is critical to utilize a screen built specifically for wet milling and to properly position the milling machine near the discharge port of the high-shear granulator.

4. Ignoring Air-Purged Seals: Air-purged seals are intended to keep an envelope of air around the granulator, preventing powder leakage and contamination. Failure to maintain these seals might result in product loss and reduced quality. Regular inspection and maintenance of air-purged seals are required to ensure their efficiency.

5. Incomplete Clean In Place (CIP) Process: The CIP process is critical for keeping the fast mixer granulator clean and functioning properly. Incomplete CIP methods might result in cross-contamination and product quality concerns. Make sure the CIP skid is properly adjusted and that all exposed surfaces, such as the main chamber, shaft seal, and chopper blade, are well cleaned.

Conclusion:

Avoiding these common mistakes is essential for ensuring the efficient and effective operation of a Rapid Mixer Granulator. Proper impeller blade design, chopper speed adjustment, wet milling process, maintenance of air-purged seals, and thorough CIP processes are key to maximizing the performance and longevity of your equipment. By following these guidelines, you can enhance the quality of your granulation processes and avoid costly errors in your operations.
