Mini Vacuum Freeze Dryer-HSYL Food Processing Equipment Manufacturer

Q: What is the energy consumption per 10kg batch of fruit?

For a standard 24-hour cycle, the HSYL-VFD10 model typically consumes between 15 and 22 kWh depending on the moisture content and ambient factory temperature.

Q: How long does a typical drying cycle take for medicinal herbs?

Most biological extracts and herbs require a total cycle time of 18 to 30 hours, which includes the 4 to 6-hour pre-freezing stage and the secondary drying phase to reach residual moisture levels below 3 percent.

Q: Can the machine be customized for 220V or 480V power?

Yes, we provide full voltage customization for 110V/220V single-phase or 380V/480V three-phase systems to match your specific regional electrical standards.

Q: What maintenance is required for the vacuum pump system?

The vacuum pump oil should be inspected every 500 operational hours and typically requires a full oil change every 1,500 hours to ensure consistent ultimate pressure levels below 10 Pa.

Q: Is the cold trap integrated or external?

In our mini units, the cold trap is typically integrated behind or below the drying chamber to save floor space, while maintaining a high surface area for vapor capture.

Q: Does the shelf temperature support heating and cooling?

The shelves are connected to a circulating thermal medium system that can cool to -40°C for pre-freezing and heat to +80°C for the sublimation and desorption phases.

Stability-Driven Engineering for Premium Extracts

Precision in lyophilization is not just about temperature; it is about the perfect synchronization between vapor pressure and latent heat. Our engineering team has integrated a Thermal Oil Circulation System within the drying shelves, ensuring that even in our smallest units, every tray experiences identical heating conditions. This eliminates the risk of "melt-back," a common failure in low-end machines where localized heating causes ice to liquefy rather than sublime.

For processors focused on the highest quality output, particularly for items like bird's nest or medicinal herbs, the pre-freezing stage is vital. We recommend integrating this machine with our standalone quick freezing equipment to create uniform ice crystals before the vacuum phase begins. This synergy minimizes primary drying times and prevents cellular wall damage in sensitive materials.

Advanced Lyophilization Mechanism and PLC Logic

The heartbeat of the unit resides in its multi-stage vacuum pump and high-surface-area cold trap. As water transitions from solid ice directly to gas, the cold trap must capture this vapor instantly to maintain the vacuum integrity. Our Optimized Vapor Path Design ensures there are no bottlenecks between the drying chamber and the condenser, keeping the sublimation rate at its theoretical maximum.

The entire process is governed by a Siemens-based PLC system. Operators can store up to 50 unique drying recipes, each with multiple temperature ramps and vacuum hold intervals. This level of automation ensures that complex materials with low eutectic points are processed with zero human error, making it a cornerstone for modern drying dehydrating machines production environments.

Versatile Use Cases in Specialized R&D and Boutique Production

While termed "Mini," this equipment delivers professional-grade throughput for specialized applications. In the nutraceutical industry, it is utilized for stabilizing the bio-activity of cordyceps and high-purity ginseng extracts where traditional drying would render the active compounds inert. In the luxury food sector, it provides the ideal platform for small-batch wagyu beef liver treats or seasonal durian crisps.

Its compact footprint makes it ideal for central kitchens or small-scale processing facilities with limited floor space. The system is designed for 24/7 continuous operation, with heavy-duty compressors and vacuum valves designed for a 10-year service life under standard industrial loads.

High-Standard Construction and International Compliance

Every Mini Vacuum Freeze Dryer leaves our factory with full BRC and B2B-ready documentation. We prioritize sanitary design, featuring Radiused Internal Corners (Zero Dead Angles) to ensure that the chamber meets the strictest USDA hygiene requirements during washdown cycles. Whether you require a standard configuration or a customized SUS316L pharmaceutical-grade setup, our engineers provide full technical support, from initial layout design to final on-site commissioning.
