LG-125 Freeze Dryer Drying Chamber – High-Efficiency Industrial Lyophilization

Product Overview

The LG-125 Drying Chamber is the core component of the LG-125 vacuum freeze-drying system, designed for precise, large-area freeze-drying of food, herbs, and pharmaceutical products. Manufactured by Shenyang Aerospace Xinyang Quick-Frozen Equipment Manufacturing Co., Ltd., the chamber integrates advanced aerospace-derived engineering, high-quality materials, and energy-efficient design to ensure stable, uniform, and reliable drying.

In freeze-drying, water in frozen products sublimates under vacuum, and the drying chamber provides the controlled environment for this critical process, maintaining temperature, vacuum pressure, and airflow to ensure nutrient and structural integrity of the products.

Key Features

• Model: LG-125 Drying Chamber

• Internal area: 125 m²

• Chamber material: 304 stainless steel for durability and corrosion resistance

• Heating system: Radiant aluminum alloy plates

• Heating temperature range: Ambient to 120°C

• Cold trap integration: Efficient water vapor capture at –30°C to –40°C

• Vacuum range: 30–133 Pa for precise sublimation

• Tray capacity: Compatible with standard aluminum trays, optimized for airflow and heat transfer

• Automation: Compatible with PLC and PC-based control for temperature and vacuum monitoring

The LG-125 drying chamber ensures uniform heating and vacuum distribution, minimizing product variation and maximizing yield.

Applications

The drying chamber is suitable for a wide range of products:

• Fruits: strawberries, apples, blueberries

• Vegetables: peas, corn, mushrooms

• Herbal and medicinal plants: ginseng, goji berries, herbal powders

• Nutritional ingredients and supplements

• Prepared meals and snacks requiring long shelf life

The controlled environment provided by the chamber allows high-quality freeze-dried products with excellent rehydration, flavor, and nutritional retention.

Operating Principles

1. Product Loading
   Frozen products are loaded onto trays and inserted into the drying chamber.

2. Vacuum Establishment
   The chamber is sealed, and vacuum pumps reduce pressure to create an environment suitable for sublimation.

3. Controlled Heating
   Radiant aluminum plates heat the trays evenly. Sublimation occurs as ice in the products turns directly into water vapor.

4. Vapor Capture
   Water vapor is captured by the integrated cold trap to maintain vacuum and prevent condensation on products.

5. Cycle Completion
   Sterile air or nitrogen is introduced to normalize pressure, and dried products are removed for inspection and packaging.

Advantages

• Uniform Drying: Even heat distribution ensures consistent product quality.

• Durable Construction: 304 stainless steel resists corrosion and wear.

• Efficient Sublimation: Integrated cold trap ensures high water removal efficiency.

• Automated Control: PLC and PC-based monitoring maintain stable temperature and vacuum.

• Versatility: Compatible with various products from fruits to herbal extracts.

Conclusion

The LG-125 Drying Chamber is a highly reliable, precision-engineered component for industrial freeze-drying applications. It provides the ideal environment for nutrient preservation, structural integrity, and flavor retention while supporting medium-scale food, herbal, and nutraceutical production.

With its advanced engineering, energy-efficient design, and compatibility with automated controls, the LG-125 drying chamber is an essential solution for manufacturers seeking high-quality, consistent freeze-dried products for both domestic and international markets.
