LG-240 Freeze-drying equipment – Large-Scale Industrial Vacuum Lyophilizer

Product Overview

The LG-240 Freeze-Drying Equipment is a high-capacity industrial Freeze Dryer designed for large-scale food, herbal, and pharmaceutical production. Developed by Shenyang Aerospace Xinyang Quick-Frozen Equipment Manufacturing Co., Ltd., this system integrates advanced aerospace-inspired technology, high-efficiency vacuum systems, and precise thermal control to produce premium freeze-dried products at industrial scale.

Freeze drying, or lyophilization, removes moisture from frozen products by sublimation under vacuum, preserving their natural shape, color, texture, flavor, and nutrients. The LG-240 is ideal for high-volume production facilities, contract manufacturers, and export-oriented food and nutraceutical companies.

Key Features

• Drying chamber model: LG-240

• Nominal drying area: 240 m² per chamber

• Number of drying chambers: 2 (2×LG-240 configuration available)

• Heating method: Radiant aluminum alloy plates

• Heating temperature range: Ambient to 120°C

• Cold trap temperature: –30°C to –40°C

• Operating vacuum pressure: 30–133 Pa

• Tray dimensions: 687×568×35 mm, high thermal conductivity aluminum trays

• Vacuum pumping time: 15–20 minutes from atmospheric pressure to 1 Torr

• Typical drying cycle: 12–24 hours depending on product type

• Integrated control system: PLC and PC-based automation for precise temperature and vacuum monitoring

The LG-240 ensures uniform heating, rapid sublimation, and high water vapor capture efficiency, delivering consistently high-quality freeze-dried products.

Applications

The LG-240 freeze dryer is used in large-scale industrial applications:

• Fruits: strawberries, blueberries, apples, mangoes

• Vegetables: peas, mushrooms, carrots, corn

• Herbal and medicinal products: ginseng, goji berries, plant extracts

• Nutritional powders and supplements: protein powders, vitamins, functional foods

• Ready-to-eat meals and snacks

• Pet food production

Products retain excellent rehydration, natural flavor, texture, and nutrients, making them ideal for export, premium retail, emergency rations, and long-term storage applications.

Operating Instructions

1. Material Preparation
   Clean, cut, and pre-treat raw materials to ensure uniform freezing and drying.

2. Tray Loading and Freezing
   Place products on trays and freeze them to below –25°C in a freezing tunnel or cold storage.

3. Vacuum Freeze Drying
   Load frozen trays into the drying chambers. The vacuum system reduces chamber pressure, while radiant heating plates sublimates ice into vapor. The cold traps capture water vapor, maintaining vacuum and preventing condensation on the product.

4. Completion and Packaging
   Introduce sterile air or nitrogen to normalize chamber pressure. Remove dried products, inspect, and package. Clean trays and prepare for the next production cycle.

Advantages

• High-Capacity Production: Large drying area allows maximum throughput

• Uniform Drying: Radiant heating plates ensure consistent quality across all trays

• Advanced Vacuum Control: Rapid and stable vacuum system minimizes product damage

• Energy Efficient: Cold traps and optimized thermal design reduce energy consumption

• Durable Construction: Stainless steel chambers and aluminum heating plates ensure long-term industrial operation

• Automation: PLC and PC-based monitoring reduces labor and improves process repeatability

Conclusion

The LG-240 Freeze-Drying Equipment provides a reliable, high-efficiency solution for large-scale industrial freeze-dried production. With advanced automation, precise temperature and vacuum control, and large drying chambers, the LG-240 ensures premium-quality freeze-dried products with excellent rehydration, nutrient retention, and long shelf life.

Ideal for food, herbal, nutraceutical, and pet food manufacturers, the LG-240 supports domestic and international markets, delivering consistent, high-quality results for industrial-scale production.
