The Vibratory Screen Machine is a critical precision sorting equipment in hollow capsule manufacturing lines, engineered to classify qualified hollow capsules by size, remove production impurities , and separate defective products . With its high-frequency vibratory technology and customized screening structure, it seamlessly integrates with capsule molding machines, polishing equipment, and inspection systems, ensuring consistent product quality and smooth downstream processes. Designed for versatility and reliability, it is a core auxiliary device for modern capsule production facilities.
Core Advantages
High-Precision Size Classification & Impurity Removal
Adopts a multi-layer vibratory screening structure (1–3 layers optional) with customized stainless steel mesh screens (aperture adjustable by capsule size). The high-frequency vibration (50–60Hz adjustable) ensures precise separation of capsules by size, while efficiently filtering out light impurities (dust, shell scraps) and defective products. The screening accuracy reaches ≥99.6%, significantly reducing manual sorting workload and minimizing product waste.
01
Gentle Handling to Preserve Capsule Integrity
Equipped with a soft-contact polyurethane lining on all internal contact surfaces and an optimized vibratory amplitude design. This minimizes friction and collision between capsules and machine parts, effectively preventing deformation, cracking, or surface scratches-critical for protecting the structural stability of gelatin, HPMC, and plant-based capsules. The low-noise vibration system (≤75dB) also ensures a comfortable working environment.
02
Versatile Compatibility & Intelligent Adjustment
Capsule Size Compatibility: Supports all standard capsule sizes (000, 00, 0, 1, 2, 3, 4, 5) with easy-to-replace mesh screens and size-adaptive fixtures. Screen replacement takes less than 10 minutes, enabling quick switching between production batches.
Material Adaptability: Ideal for sorting gelatin capsules, vegetarian HPMC capsules, and plant-based (e.g., pullulan) capsules. The adjustable vibration frequency and feeding speed allow precise matching to different material properties (e.g., density, brittleness).
Intelligent Control: Features a PLC control system with a 7-inch touch screen. Operators can store parameters for up to 20 different capsule types, enabling one-click startup and automatic adjustment. Real-time monitoring of screening efficiency and equipment status is also available.
03
High Efficiency & Energy-Saving Design
Optimized internal flow channel design reduces material blocking, with a processing capacity of 80,000–350,000 capsules/hour-25% higher than traditional models.
Equipped with an energy-efficient motor (IE3 standard) and variable frequency drive (VFD), reducing power consumption by 18% while ensuring stable vibration performance.
Modular structure allows tool-free disassembly of screening layers and feeding hoppers, simplifying cleaning and maintenance and reducing downtime.
04
Compliance with Global Industry Standards
Constructed with food-grade 304/316L stainless steel (contact parts) to meet GMP, FDA, and EU CE requirements. The fully enclosed design prevents cross-contamination and dust emission, adhering to strict pharmaceutical and nutraceutical production hygiene standards. All materials are non-toxic, odorless, and resistant to corrosion by cleaning agents.
05
FAQ
Q: What capsule sizes can the separator handle?
A: Our hollow capsule vibratory screen machine is compatible with all standard capsule sizes, including 000, 00, 0, 1, 2, 3, 4, and 5. It can be adapted to different sizes by replacing the corresponding change parts (e.g., customized mesh screens), which are easy to install and replace.
Q: Can this separator work with different types of hollow capsule materials?
A: Yes, it is designed to handle various common hollow capsule materials, such as gelatin, HPMC (hydroxypropyl methylcellulose), and plant-based materials. The machine adopts a gentle handling design with a soft-contact inner lining, which minimizes friction and avoids damage to capsules made of different materials.
Q: How to choose the right separator model for my production line?
A: The key selection criteria include your production capacity (capsules per hour) and capsule size. Our typical models have a processing capacity ranging from 80,000 to 300,000 capsules per hour. For small-scale R&D laboratories or pilot production, we recommend compact models with lower capacity; for large-scale manufacturing facilities, high-capacity models (e.g., 1500 pcs/min and above) are more suitable. Additionally, ensure the model complies with your local industry standards (e.g., GMP, FDA).
