Pellet Quality and Coating Efficiency with VJ Instruments' Spheronizer Machines

1. Pellet Quality and Coating Efficiency with VJ Instruments' Spheronizer Machines Introduction In pharmaceutical, nutraceutical, and chemical manufacturing, the demand for precise and uniform pellet formation is growing rapidly. Pelletisation not only improves product stability and dosing accuracy but also plays a critical role in achieving efficient coating, especially during sugar coating and film coating processes. At the heart of this technology lies the spheronizer machine—a sophisticated device engineered to convert extrudates into high-quality, spherical pellets. VJ Instruments, a leading manufacturer of scientific and lab equipment, offers state-of-the-art spheronizers that deliver unmatched consistency, performance, and reliability. What is a Spheronizer? A spheronizer is a specialised machine used in conjunction with an extruder to transform cylindrical extrudates into uniform spherical pellets or granules. This is essential in processes where shape uniformity enhances product performance, such as controlled drug release or coating. The spheronization process involves: 1. Extrusion – Raw material is forced through a die to form rods. 2. Spheronization – These rods are broken and rolled into spheres in the spheronizer. The outcome is uniform, dense, and smooth pellets that are ideal for further processing, including sugar coating and film coating. VJ Instruments’ Spheronizer Machines – Engineered for Precision VJ Instruments offers advanced spheronizer machines that are widely used in pharmaceutical R&D labs and small-scale production environments. Our machines are designed with user-friendliness, precision, and durability in mind. Key Features: ● Adjustable Speed Control: Allows operators to fine-tune rotational speed for optimal spheronisation. ● Durable Friction Plate: Ensures uniform shearing and rounding of particles.

2. ● Compact and Modular Design: Suitable for benchtop or pilot-scale applications. ● Easy Cleaning and Maintenance: Made with stainless steel and smooth surfaces to comply with GMP standards. Our spheronizer units are compatible with various formulations, including those requiring post-spheronization coating, making them versatile tools for formulators and researchers. Why Spheronization Matters in the Pharmaceutical Industry The pharmaceutical sector requires strict uniformity in dosage forms. Granules or pellets produced via extrusion and spheronization are used for: ● Controlled or sustained drug release ● Taste masking ● Layered drug delivery ● Improved bioavailability Spheronization ensures that these pellets have: ● High mechanical strength ● Excellent flow properties ● Minimal dust generation ● Consistency in size, which is crucial for even coating Without uniform pellets, subsequent sugar coating and film coating can become uneven, resulting in poor product performance or appearance. Applications of Spheronizer Machines While spheronizers are most prominently used in pharma, they are also valuable in: ● Nutraceutical production – For creating herbal or vitamin granules ● Agricultural industries – For uniform pesticide or fertiliser granules

3. ● Catalyst manufacturing – Where spherical particles enhance reaction efficiency ● Cosmetic formulations – For creating exfoliating beads and delivery systems Their ability to support downstream coating processes makes them highly beneficial for businesses looking to improve both product functionality and aesthetic appeal. Sugar Coating and Film Coating – The Perfect Follow-Up to Spheronization Once spheronized pellets are formed, they are typically coated to enhance their utility. VJ Instruments' spheronizer machines are designed to produce pellets that are ideal for both sugar coating and film coating. 1. Sugar Coating This traditional method uses layers of sugar-based solutions to coat tablets or pellets. Benefits include: ● Taste masking ● Improved appearance ● Increased durability Spheronized pellets are ideal for sugar coating due to their smooth, round surfaces, which allow the sugar layers to bind evenly without cracking or deforming. 2. Film Coating Film coating involves the application of a thin polymer-based film over the pellet. It offers: ● Moisture protection ● Controlled drug release ● Colour customisation ● Protection from environmental conditions Uniform pellets created by our spheronizers ensure the film coating spreads evenly and dries uniformly, reducing batch rejection and improving final product quality.
