Freeze-Drying for Health Supplements: Better Process Control for High-Value Products. 🌿❄️
Health supplements often contain temperature-sensitive ingredients, botanical extracts, fruits, probiotics, proteins and other functional materials.
When these products need to be dried, conventional high-temperature drying may create unnecessary thermal stress.
Vacuum freeze drying provides a controlled low-temperature alternative.
At Kassel Machinery, we provide customized freeze-drying systems designed for different supplement products, batch sizes and production requirements.
❄️ Why Freeze Dry Health Supplements?
A typical freeze-drying process includes:
Freezing → Primary Drying → Secondary Drying
The product is first frozen. Under vacuum, ice is removed through sublimation rather than conventional liquid ev***ration.
This controlled process can help:
✔ Reduce thermal stress
✔ Preserve product structure
✔ Protect sensitive components
✔ Maintain color, flavor and appearance
✔ Produce a lightweight, porous product
✔ Improve rehydration performance for suitable formulations
The actual results depend on the formulation, product characteristics and drying process.
⚙️ Intelligent Automatic Control
Kassel freeze dryers automatically monitor, control and record key operating parameters, including:
• Temperature
• Chamber pressure
• Electrical current
• Process status
Different products can use different drying recipes.
Operators can select the corresponding program through the touchscreen HMI, and the system can then execute the programmed freeze-drying cycle automatically.
🌍 Multilingual HMI
For international customers, the touchscreen interface supports:
Chinese · English · Spanish
The intuitive interface makes daily operation easier for both experienced operators and new users.
🔧 Reliable Components
Equipment reliability starts with the components.
Kassel focuses on using new and reliable components from qualified suppliers, rather than used or low-quality parts.
Customers can select suitable refrigeration compressors and vacuum pumps according to their project requirements and configuration.
For refrigeration systems, Kassel uses refrigerant options such as R404A or R507 instead of R22, according to the applicable system design and project requirements.
🏭 Two Freeze Dryer Configurations
Different production scales require different equipment structures.
TYPE 01 | Contact-Type Freeze Dryer
Designed mainly for small and medium-scale production, with typical freeze-drying capacities below approximately 300 kg per batch and shelf areas up to around 30 m², depending on the configuration.
A major advantage:
Freezing + Drying in the Same Chamber
This can be a practical solution when the customer does not have a separate pre-freezing chamber.
Typical configuration includes:
• Drying chamber
• Heated shelves
• Product trays
• V***r condenser
• Refrigeration system
• Vacuum system
• Heating system
• Defrosting system
• Automatic control system
Material options include:
SUS304 food-grade stainless steel or SUS316 stainless steel, depending on application requirements.
TYPE 02 | Large Modular Freeze Dryer
Designed for larger industrial production, with typical capacities of approximately 500–2,000 kg per batch, depending on product and process conditions.
The system uses a modular structure for transportation and on-site installation.
Main modules include:
• Drying chamber
• V***r condenser
• Refrigeration unit
• Vacuum unit
• Heating unit
• Trolley & rail loading system
• Freezing chamber
• Control system
A separate freezing chamber can help improve production efficiency by separating freezing and drying operations.
The system is designed for shipment using a 40-foot flat-rack container, with engineers providing on-site installation guidance to assemble the modules into a complete freeze-drying system.
The chamber, doors and v***r condenser can be configured with SUS304 stainless steel, while aluminum trays and trolley/rail loading systems are available according to the project design.
⚡ Flexible Power Options
Depending on the destination market and project requirements, available configurations can include:
110V / 60Hz / Single Phase
or
400–480V / 50–60Hz / Three Phase
Final electrical configuration is confirmed according to the customer's site and local power standards.
