Lanende Intelligent Technology Launches Next-Generation Vacuum Freeze Dryer to Empower Long-Term Preservation in Bio & Food Industries

April 13, 2026 — Shandong Lanende Intelligent Technology Co., Ltd. has officially unveiled its newly upgraded vacuum freeze dryer series (models LD-DG10 to LD-DG50+), delivering advanced, stable, and efficient lyophilization solutions for industries including pharmaceuticals, food processing, agriculture, and chemicals. The launch reinforces the company’s core vision: “Empowering enterprise efficiency through technology.”

Technical Highlights: Three Core Advantages Set a New Industry Benchmark

1. High-Efficiency Condensation System

The system features an imported hermetic compressor, ensuring rapid cooling and high efficiency, paired with eco-friendly refrigerants compliant with environmental standards.

Maximum ice condenser capacity: ≥3 kg

Minimum working temperature: ≤ -60°C

Uniform internal temperature with optimized gas flow design for efficient drying and water capture

Durable 304 stainless steel cold trap with external coil design for pre-freezing, eliminating the need for ultra-low temperature freezers or liquid nitrogen

2. Precision Vacuum System

The high-sealing chamber achieves an ultimate vacuum of ≤10 Pa, supported by:

Fine vacuum control valve

Customized vacuum generator (pumping speed: 2 L/s)

Pirani vacuum gauge for accurate pressure monitoring

An optional oil mist filter helps reduce laboratory contamination and ensures operator safety.

3. Intelligent Drying & Control System

Designed for flexibility and ease of use:

Freeze-drying area up to 0.19 m² with multi-manifold expansion

Transparent corrosion-resistant chamber for real-time observation

Stoppering shelves compatible with vials

The system is equipped with a 7-inch full-color touchscreen, displaying real-time temperature, vacuum, and runtime data.

Additional smart features include:

Automatic data storage and USB export

Maintenance reminders for compressor and vacuum pump

Password protection and multi-layer sample protection mechanisms

Wide-Ranging Applications Across Industries

The LD-DG series supports diverse use cases:

Pharmaceuticals & Biologics: Preservation of drugs, vaccines, and bio-products while maintaining activity

Food Industry: Retains color, flavor, and nutrition in freeze-dried products

Agriculture: Extends seed storage life with high germination rates

Chemical & Environmental Fields: Stabilization of catalysts, pigments, sludge, and wastewater materials

Scientific Research: Sample preparation for advanced studies

Scenario-Based Solutions for Seamless Integration

Microbial Strain Long-Term Preservation Solution

Using a three-stage process (pre-freezing, sublimation drying, desorption drying), with pre-freezing at -35°C to -40°C:

Storage lifespan of 10–20 years

High survival rate and genetic stability

Vacuum monitoring and automatic sealing

Automated Sample Preparation & Acid Concentration Solution

Integrated with microwave digestion, graphite digestion, and nitrogen blowdown systems to:

Improve dehydration and concentration efficiency

Reduce human error

Enhance laboratory throughput

Smart Technology: From Equipment to Intelligent Systems

By integrating IoT technology, Lanende enables:

Remote monitoring

Cloud data storage

Intelligent management

This builds a “smart testing and processing network”, improving efficiency, reducing loss, and ensuring consistent quality.

Market Impact and Industry Significance

The new series delivers not only advanced hardware performance but also full-process integration, from sample preparation to data management.

For high-value materials, this means:

Shorter processing cycles

Controlled, sterile environments

Improved product consistency and safety

Conclusion

From laboratory research to industrial production, Lanende’s vacuum freeze dryers transform complex freeze-drying into a controlled, traceable, and scalable process.

By combining innovation with practical solutions, Lanende continues to support industrial advancement and long-term product preservation across global markets.
