LG-200 Freeze Drying Equipment – Industrial Vacuum Lyophilizer

Product Overview

The LG-200 Freeze Drying Equipment is a medium-to-large capacity industrial Freeze Dryer designed for food, herbal, and pharmaceutical production. Developed by Shenyang Aerospace Xinyang Quick-Frozen Equipment Manufacturing Co., Ltd., this system integrates aerospace-derived technology with advanced freeze-drying engineering to deliver high-quality, nutrient-preserving products.

Freeze-drying, or lyophilization, removes moisture from frozen products by sublimation under vacuum, preserving the natural shape, color, texture, aroma, and nutrients. The LG-200 is ideal for food processors, nutraceutical manufacturers, and research laboratories that require reliable, uniform, and energy-efficient drying.

Technical Specifications

• Drying chamber model: LG-200

• Nominal drying area: 200 m² per chamber

• 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

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

• Typical drying cycle: 12–24 hours (depends on product)

• Tray dimensions: Standard aluminum alloy trays with high thermal conductivity

The LG-200 ensures uniform heating, precise vacuum control, and efficient water vapor capture, resulting in high-quality freeze-dried products.

Applications

The LG-200 freeze dryer is widely used in industries including:

• Freeze-dried fruits: strawberries, blueberries, apples, mangoes

• Freeze-dried vegetables: peas, carrots, mushrooms, corn

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

• Nutritional powders and supplements

• Ready-to-eat meals and premium snacks

Freeze-dried products retain excellent rehydration properties, long shelf life, and superior flavor and nutritional value, making them ideal for export, premium retail, emergency food, and outdoor meals.

Operating Instructions

1. Material Preparation
   Clean, cut, and pre-treat raw materials according to product specifications.

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

3. Vacuum Freeze Drying
   Load frozen trays into the drying chamber. The vacuum system reduces pressure, while the condenser captures sublimated water vapor. Radiant heating plates gently and evenly sublimate ice into vapor without damaging the product.

4. Completion and Unloading
   Sterile air or nitrogen is introduced to normalize chamber pressure. Dry products are removed, inspected, and packaged. Trays are cleaned and reused for the next production cycle.

Advantages

• High Production Efficiency: Optimized drying chambers provide uniform heat and rapid sublimation.

• Precision Control: Automated temperature and vacuum management ensure consistent product quality.

• Energy Efficiency: Advanced radiant heating and cold trap systems minimize energy consumption.

• Versatility: Suitable for a wide range of products from fruits and vegetables to herbal extracts and supplements.

• Durable Construction: High-quality stainless steel and aluminum materials ensure long service life.
