Soft Gel Capsule Manufacturing Machine Guide
1. Soft Gel Capsules Preparation Process
Gelatin Preparation → Material Preparation → Encapsulation → Drying → Inspection & Packaging
Gelatin Melting Tank
Spreader Box & Casting Drum
Injection Wedge
Die Roll System
Tumble Dryer
Step 1
Gelatin Melting
Gelatin, water and plasticizer are mixed and heated in a melting tank. Vacuum degassing is performed at -0.07 to -0.08 MPa to eliminate bubbles. After degassing, the gelatin is rested for more than 4 hours.
Step 2
Material Preparation
Solution preparation should be carried out according to the specific requirements of the project. If the raw materials are sensitive to light, heat, or oxygen, special treatment is required. The solution preparation process varies from project to project.
Step 3
Encapsulation
Gelatin ribbons are formed and filled with prepared material through the die system.
Recommended ribbon thickness:
- ≥1 g capsule: 0.8–0.9 mm
- <1 g capsule: 0.7–0.8 mm
Step 4
Drying
Controlled temperature, humidity and airflow. Final shell moisture maintained at 8–12%. It is easy to store and transport, and it is not too soft.
Step 5
Inspection & Sorting
Manual inspection under light tables to remove defective capsules.
Soft capsules that have problems such as size, shape, or air bubbles.

4. Softgel Encapsulation Machine Parts
Key spare parts for softgel encapsulation machines include die rolls, injection wedges, feeding pump assemblies, spreader box components, product-contact tubing, sealing elements, lubrication systems and monitoring components.
Timely replacement of these parts ensures stable machine operation, precise filling, and reliable capsule sealing.
(1). Softgel Die Rolls
Die rolls determine capsule shape, size and sealing quality. As essential components used in daily production, they are among the fastest-wearing parts.
After extended operation, maintenance or replacement is necessary to maintain forming accuracy and sealing integrity.
When to repair or replace:
- Declining sealing performance
- Capsule deformation
- Increased material leakage
(2). Injection Wedge
The injection wedge is positioned between the gelatin ribbons. It heats the gelatin and accurately injects the fill material to complete encapsulation.
Operating continuously under high temperature and material flow, it is a wear component. Surface wear may affect heat distribution, leading to leakage or unstable injection.
The upgraded heating element uses improved carrier materials, providing longer service life, more uniform heating, cleaner sealing cuts and easier capsule separation.
(3). Feeding Pump Assembly
The material hopper and dosing pump are critical for precise filling control.
The hopper is typically made of stainless steel with a conical design to ensure smooth material flow. It can be equipped with an agitator and insulation system as required, and can connect to a feeding system for continuous supply.
The dosing pump transfers material to the injection wedge and enables accurate dosage control. Different pump types can be configured according to material characteristics.
(4). Gelatin Spreader Box Components
Two gelatin boxes are mounted on rotating drums at both sides of the machine. Liquid gelatin is cast onto the drums to form gelatin ribbons, which become the capsule shell.
Ribbon thickness can be adjusted according to capsule weight or specific production requirements.
(5). Product-Contact Tubing & Silicone Components
Silicone tubing for peristaltic pumps, connectors between gelatin tanks and spreader boxes, and material transfer components are in direct contact with the product.
Exposure to oil, solvents and heat may cause gradual wear. Regular cleaning and replacement are recommended.
(6). Seals & O-Rings
Typical sealing components include piston seals, hydraulic seals, Teflon retainers and gaskets.
Wear or aging may lead to leakage, pressure loss or contamination risks.
(7). Lubrication & Filtration Components
The lubrication pump supplies oil to gelatin ribbons and die roll assemblies to prevent sticking.
Die roll assemblies use mechanical oil lubrication, while other components use pharmaceutical-grade paraffin oil. Proper lubrication ensures smooth operation and extended equipment lifespan.
(8). Drying System Accessories
Oil-absorbing cloth inside the drying tumbler is a common consumable item.
High-quality materials compliant with EU food-contact standards help remove excess surface oil and improve capsule quality.
(9). Sensors & Monitoring Components
The softgel machine is equipped with multiple sensors to ensure stable operation, including injection wedge temperature sensors, liquid level sensors and pressure sensors.
These components provide rapid feedback for early detection and resolution of operational issues.
