Their ability to efficiently produce high-quality softgel capsules is unmatched. In this post, you'll learn about the main parts of a Softgel Encapsulator, including the medicine hopper, injection wedge, and more. Discover how these components enhance functionality and efficiency in softgel manufacturing equipment.
The medicine hopper and pump are vital components in any softgel encapsulator, playing a key role in the softgel encapsulation process. The medicine hopper acts as a reservoir, holding the liquid fill material—whether pharmaceutical or nutraceutical—that will be encapsulated. It is designed to maintain the material at the right temperature and consistency, often equipped with a stirrer and heat preservation system. This ensures that the fill material remains homogeneous and ready for precise dosing.
The pump connected to the hopper is responsible for delivering the fill material with high precision. It controls the flow rate and volume, ensuring each softgel capsule receives the exact dosage required. This precision is critical, especially in pharmaceutical applications where dosage accuracy affects efficacy and safety. Automated systems integrated into the pump help maintain consistent pressure and flow, reducing human error and improving product uniformity.
Together, the medicine hopper and pump form the foundation for reliable softgel production. They ensure a steady and controlled supply of the fill material to the injection wedge, where encapsulation occurs. In high speed softgel encapsulation machines, these components must operate flawlessly to keep up with rapid production rates without compromising dosage accuracy.
Key features of the medicine hopper and pump include:
Material Supply Role: Holds and maintains the fill material ready for encapsulation.
Precision Dosage Control: Accurately meters the fill volume for each capsule.
Automation for Consistency: Sensors and control systems monitor fill levels and flow, triggering alarms or stopping the process if issues arise.
The design of these components varies depending on the softgel manufacturing equipment model and manufacturer. Some advanced softgel encapsulation machines offer customizable hopper configurations and pumps suited for different fill materials, such as oils, pastes, or suspensions.
By understanding the functionality of the medicine hopper and pump, operators can better maintain the softgel encapsulator, troubleshoot issues, and optimize production efficiency.
The injection wedge is a crucial part of the softgel encapsulation machine components. Positioned precisely between the die rolls, it serves as the point where the fill material is injected into the gelatin ribbons. This part ensures the softgel encapsulation process runs smoothly by accurately depositing the fill material into each capsule pocket.
The wedge’s location is strategic—it sits snugly between the two die rolls, which form the gelatin ribbons into capsule shapes. As the ribbons pass through the die rolls, the injection wedge injects the fill material into the pockets created by the gelatin sheets. This precise timing and positioning are essential to prevent any fill leaks and ensure each softgel capsule is uniformly filled.
A well-designed injection wedge also helps maintain the integrity of the softgel capsules by preventing leaks during the high speed softgel encapsulation process. It must withstand continuous operation and maintain tight seals to avoid contamination or loss of fill material. Manufacturers often equip the wedge with advanced control systems to monitor injection pressure and flow, ensuring consistent capsule quality.
Key features of the injection wedge include:
Positioning Between Die Rolls: Correct placement allows for accurate fill deposition.
Accurate Fill Material Deposit: Ensures each capsule receives the right amount of fill.
Leak Prevention and Uniformity: Maintains capsule integrity and consistent shape.
In softgel manufacturing equipment, the injection wedge’s design may vary depending on the softgel machine manufacturer and model. Some machines use pneumatic or servo-driven wedges for quieter and more precise operation. These advanced features contribute to higher production efficiency and better capsule quality.
Overall, the injection wedge plays a pivotal role in the softgel encapsulation technology. It bridges the gap between the medicine hopper and the die roll assembly, making sure the fill material is perfectly integrated into the gelatin shell.
Tip: Regularly inspect and calibrate the injection wedge to prevent leaks and maintain uniform fill distribution, especially during high speed softgel encapsulation.
The gelatin melting and service tanks are fundamental parts of the softgel encapsulation machine components. They prepare and maintain the gelatin in a liquid form suitable for forming the capsule shells. This step is critical in the softgel encapsulation process because the quality and consistency of the gelatin directly impact the final product.
The gelatin melting tank heats solid gelatin sheets or granules until they become a uniform liquid. Precise temperature control is essential here to avoid overheating, which can degrade the gelatin's properties, or underheating, which results in poor flow and uneven ribbon formation. The tank usually includes a jacketed heating system with steam or hot water circulation, ensuring even heat distribution.
Maintaining the correct viscosity of the gelatin solution is vital. The service tank holds the melted gelatin at a stable temperature, preventing it from thickening or cooling prematurely. This consistency ensures the gelatin can be smoothly spread onto the casting drum to form ribbons. Sensors and automated temperature controllers integrated into the tanks help maintain optimal conditions, which supports high speed softgel encapsulation without interruptions.
Together, the melting and service tanks provide a continuous, steady supply of gelatin to the spreader box and casting drum. This uninterrupted flow is crucial for maintaining production efficiency and capsule uniformity. Any fluctuation in gelatin supply or temperature can cause defects in the capsules or slow down the softgel manufacturing equipment.
In advanced softgel encapsulators, tanks may include agitation systems to keep the gelatin homogeneous and prevent sedimentation. Some manufacturers offer customizable tank designs to accommodate different gelatin types or formulations.
The spreader box and casting drum are essential components in softgel manufacturing equipment. They work together to form the gelatin ribbons that become the softgel capsule shells, a critical step in the softgel encapsulation process.
The spreader box evenly distributes the melted gelatin onto the surface of the casting drum. This even coating is crucial because it determines the thickness and uniformity of the gelatin ribbon. The gelatin must be spread smoothly to avoid any inconsistencies, which could lead to weak spots or irregular capsules.
Once the gelatin is spread, the casting drum rotates and cools the gelatin film. The drum’s surface temperature is carefully controlled to solidify the gelatin at an optimal rate. This cooling process transforms the liquid gelatin into a thin, flexible ribbon that can be handled easily during encapsulation. Proper cooling prevents bubbles or wrinkles, ensuring the ribbon’s quality.
Maintaining consistent ribbon thickness is vital for producing high-quality softgel capsules. Adjustable screws on the spreader box allow operators to fine-tune the gelatin layer’s thickness. Uniform ribbons lead to capsules with consistent shell strength and appearance. Sensors and temperature controls integrated into the spreader box and casting drum monitor the process, supporting high speed softgel encapsulation without compromising quality.
Together, the spreader box and casting drum form the foundation for the gelatin shell, linking the gelatin melting tanks to the die roll assembly. Their precise operation impacts the entire softgel encapsulation machine’s efficiency and output quality.
Key features include:
Even gelatin distribution by the spreader box
Controlled cooling on the casting drum
Adjustable ribbon thickness for uniformity
Integrated temperature and tension controls
These features make the spreader box and casting drum indispensable in softgel encapsulation technology. Different softgel machine manufacturers may offer variations in design, but the core function remains the same: producing consistent gelatin ribbons to ensure flawless capsule formation.
The die roll assembly is a central part of the softgel encapsulator, playing a key role in shaping the gelatin ribbons into precise capsule forms. This component consists mainly of two die rolls mounted on shafts, a stripper, and a mangle roller, all working in harmony to ensure smooth and accurate softgel capsule production.
The two die rolls face each other and rotate synchronously. As the gelatin ribbons pass between these rolls, the die cavities cut and shape the ribbons into the desired capsule shapes. The left die roll can move laterally to adjust alignment, while the right die roll rotates to match the speed and timing of the machine. This precision ensures that the gelatin sheets are pressed tightly and evenly, forming well-defined capsule shells.
The die roll assembly is crucial for the softgel encapsulation process because it directly affects capsule quality. The alignment device behind the die roll housing allows fine-tuning to ensure the left and right dies correspond perfectly. This alignment prevents capsule defects like uneven thickness or incomplete sealing. The die roll housing also contains the gearing system powered by the main motor, which synchronizes the die rolls, feeding pump, and other rollers for consistent capsule formation during high speed softgel encapsulation.
Once the capsules are formed, the stripper removes them from the die rolls. It uses hexagonal shafts and brushes to gently detach capsules that may stick to the gelatin ribbon or die surface. This prevents damage and maintains capsule integrity.
The mangle roller follows the stripper. It consists of two opposing tooth shafts that rotate to guide the mesh gelatin (excess gelatin film) away from the capsules. The mangle roller ensures the mesh gelatin moves in sync with the die rolls, facilitating smooth capsule transfer to the next stage. The mangle roller’s speed adjusts automatically with the main motor, maintaining perfect timing during production.

This assembly is a core part of softgel manufacturing equipment and often differentiates softgel machine manufacturers by design and precision. Proper maintenance and calibration of the die roll assembly are essential to achieve high quality and efficient softgel production.
The lubrication system is a critical component in softgel encapsulation machines, designed to ensure smooth operation and prevent gelatin sheets from sticking during the production process. It consists of several parts, including a motor, lubrication oil pumps, oil tanks, and pipelines, all working together to deliver the right amount of lubricant precisely where it is needed.
One of the most important roles of the lubrication system is to apply a thin, even layer of lubricant—usually medical-grade paraffin oil—onto the gelatin ribbons before they reach the die roll assembly. This lubrication prevents the gelatin sheets from sticking to the die rolls and to each other. Without proper lubrication, the gelatin ribbons could tear or deform, leading to defects in the softgel capsules and production downtime.
The lubrication system also lubricates the gearing units in the die roll housing assembly and the feeding pump. These parts require mechanical oil lubrication to reduce friction and wear during high speed softgel encapsulation. By keeping these moving parts well-lubricated, the system supports continuous, efficient operation and extends the lifespan of the softgel production machinery.
The lubrication oil pump circulates the lubricants through pipelines to the designated areas. The system is typically located at the back of the machine frame for easy access during maintenance. Proper lubrication ensures the encapsulation machine maintains optimal performance and prevents costly repairs caused by mechanical failure or gelatin damage.
Regular monitoring of the lubrication system is essential. Operators should check oil levels in the tanks, inspect pipelines for blockages or leaks, and verify that the oil pumps are functioning correctly. Over-lubrication can be as problematic as insufficient lubrication, potentially affecting capsule sealing quality. Therefore, fine-tuning the lubrication flow rate is vital.
Some advanced softgel encapsulation machines include sensors and automated controls to maintain consistent lubrication levels, adapting to changes in machine speed or production conditions. This automation helps maintain the balance between lubrication efficiency and capsule quality.
In summary, the lubrication system is a key feature of softgel encapsulation technology that supports both the gelatin ribbon handling and the mechanical components. Its proper function is indispensable for smooth, high speed softgel encapsulation and consistent capsule quality.
Tip: Schedule routine checks of the lubrication system’s oil levels and pump operation to prevent gelatin sticking and mechanical wear during continuous softgel production.
The conveyor and tumble dryer are essential components in the softgel encapsulation machine, playing a critical role in the post-encapsulation phase of the softgel encapsulation process. After the softgel capsules are formed by the die roll assembly and separated by the stripper and mangle rollers, they need to be carefully transported and dried to maintain their shape and quality.
The conveyor system is designed to transfer the freshly formed softgel capsules smoothly from the encapsulation area to the drying section. It consists of a motor-driven conveyor belt with an adjustable tensioning device. This adjustability helps maintain the right belt tightness to prevent slippage or excessive wear. The conveyor is positioned just after the mangle roller, ensuring capsules are collected efficiently without damage.
During operation, the conveyor belt moves the capsules forward at a controlled speed, which can be synchronized with the overall machine speed. This synchronization is vital in high speed softgel encapsulation to avoid bottlenecks or capsule pile-ups. Additionally, the conveyor can reverse direction when needed to transfer scrap capsules into a separate collection tank, helping maintain a clean production environment.
Capsules are delicate immediately after formation and can stick to each other or the conveyor belt if not handled properly. To prevent this, the conveyor system is designed with smooth surfaces and sometimes includes gentle air blowing mechanisms or vibration features to keep capsules separate. This reduces the risk of capsule deformation or damage, which would affect product quality and yield.
Once transported, the capsules enter the tumble dryer, a specialized drying chamber that gently agitates the capsules to remove excess moisture. The tumble dryer’s rotating drum or tumbler ensures capsules move freely, exposing all surfaces to drying air. This agitation prevents capsules from sticking together and promotes uniform drying.
Effective drying is crucial for maintaining capsule integrity, preventing brittleness, and extending shelf life. The drying process can take several hours to days, depending on the formulation and capsule size. Operators can adjust drying parameters such as temperature, airflow, and tumble speed via the machine’s control system, often integrated with the PLC touch screen for precision control.
Together, the conveyor and tumble dryer form an indispensable part of the softgel production machinery. They ensure that capsules are handled gently post-encapsulation, preserving their shape and quality before packaging.
Key features of the conveyor and tumble dryer include:
Motorized conveyor belt with adjustable tension
Smooth capsule transfer synchronized with machine speed
Reverse operation for scrap capsule handling
Tumble dryer with gentle agitation for uniform drying
Adjustable drying parameters for optimal moisture removal
These features support continuous, high speed softgel encapsulation while maintaining product quality and reducing downtime.
The PLC touch screen is the central control hub of a softgel encapsulator. It provides operators with a user-friendly interface to monitor and manage the entire softgel encapsulation process in real time. This advanced control system integrates various sensors and actuators, allowing precise adjustments to machine parameters such as temperature, fill volume, speed, and pressure.
Through the PLC touch screen, operators can start, pause, or stop the machine and configure settings for each stage of production. This centralized control simplifies the operation of complex softgel manufacturing equipment, making it easier to maintain consistent quality and optimize production efficiency. The screen typically displays key operational data, including the status of the medicine hopper, gelatin temperature, die roll speed, and lubrication system performance.
One of the most valuable features of the PLC touch screen is its ability to provide real-time data and alerts. It continuously monitors critical parameters and immediately notifies operators if any values fall outside preset limits. For example, if the gelatin temperature drops below the required range or if the medicine pump flow rate fluctuates, the system issues alarms. This quick feedback helps prevent defects, reduces downtime, and supports high speed softgel encapsulation by enabling rapid troubleshooting.
Automation through the PLC touch screen enhances precision and consistency in softgel production. It can automatically adjust machine functions based on real-time feedback, such as regulating the injection wedge pressure or synchronizing the die roll assembly speed with the feeding pump. This automation minimizes human error and ensures each softgel capsule meets strict quality standards.
Many modern softgel encapsulation machines also allow data logging and remote monitoring via the PLC system, facilitating quality control and maintenance planning. The touch screen interface often supports multiple languages and customizable layouts, improving usability across different operators and manufacturing environments.
