Understanding the key specifications ensures optimal performance and compatibility with production goals, while a structured maintenance routine maximizes machine lifespan, product quality, and operational safety.

Key Specifications to Consider

Production Capacity

Production capacity refers to the number of capsules a machine can produce within a given time frame—typically measured in units per hour (UPH) or per day. This specification is critical for matching machine output to production demands.

High-capacity machines (e.g., 30,000–100,000 UPH) are ideal for large-scale manufacturing, while semi-automatic or benchtop models (500–5,000 UPH) suit research labs or small-batch producers. Selecting the right capacity ensures efficiency without over-investment in unnecessary throughput.

Power Consumption

Power consumption indicates the electrical energy required to operate the encapsulation machine, usually expressed in kilowatts (kW) or watts (W). This affects both operational costs and facility power requirements.

Smaller machines may consume 1–3 kW, whereas fully automated systems can require 5–15 kW depending on automation level and production speed. Energy-efficient models with variable speed drives or standby modes help reduce long-term operating expenses and support sustainability goals.

Encapsulate Type and Size Compatibility

The machine must be compatible with the desired capsule type—such as gelatin, vegetarian (HPMC), or pullulan—and capable of handling various capsule sizes (e.g., 00, 0, 1, 2, 3, 4, 5).

Size 00 capsules are commonly used for higher fill volumes, while size 5 is among the smallest, suitable for precise dosing. Some machines offer quick-change tooling kits to switch between sizes efficiently. Always verify compatibility with your formulation and consult the supplier for customization options or regulatory compliance (e.g., FDA, GMP).

Material Construction and Component Design

The materials used in critical components—such as the feeding hopper, encapsulation plates, tamping pins, and conveyor systems—must be compatible with diverse formulations, including powders, granules, and semi-solids.

High-grade stainless steel (e.g., SS316L) is standard for parts in contact with product due to its corrosion resistance, cleanability, and durability. Seals and gaskets are typically made from FDA-approved elastomers. Smooth, crevice-free surfaces minimize residue buildup and support CIP (Clean-in-Place) procedures.

Dust-Free and Sterile Operation

For sensitive applications—especially in sterile or controlled environments—encapsulation machines should integrate dust containment systems or be compatible with isolators and cleanroom setups (e.g., ISO Class 5–8).

Features such as HEPA-filtered enclosures, negative pressure zones, and glove ports help prevent cross-contamination and ensure operator safety. These systems are crucial for handling potent compounds, allergens, or sterile dosage forms, maintaining both product integrity and regulatory compliance.

Machine Dimensions and Footprint

The physical dimensions (length, width, height) and weight of the machine impact installation, facility layout, and accessibility for maintenance. Compact models are suitable for limited spaces or modular production lines.

Consider clearance for loading materials, accessing internal components, and integrating auxiliary systems (e.g., vacuum, compressed air, or downstream packaging). Mobile units with casters offer flexibility, while larger machines may require permanent mounting and vibration damping.
