LG-125 Freeze Drying Equipment – Industrial Vacuum Lyophilizer

Product Overview

The LG-125 Freeze Drying Equipment is a medium-capacity industrial Freeze Dryer designed for small to mid-scale food processing, pharmaceutical, and herbal production. Developed by Shenyang Aerospace Xinyang Quick-Frozen Equipment Manufacturing Co., Ltd., this system combines advanced aerospace-derived technology with proven freeze-drying expertise to deliver high-quality, nutrient-preserved products.

Freeze drying, also known as lyophilization, removes moisture from frozen materials by sublimation under vacuum, preserving the original shape, color, texture, flavor, and nutritional value. The LG-125 is ideal for food processors, nutraceutical manufacturers, and R&D laboratories requiring precise and reliable drying of sensitive products.

Key Technical Specifications

The LG-125 ensures uniform temperature distribution, efficient water vapor capture, and precise vacuum control, making it suitable for products that require gentle drying.

Application Scenarios

The LG-125 freeze dryer is widely used in food, herbal, and nutraceutical industries, including:

• Fruits: strawberries, blueberries, apples

• Vegetables: peas, corn, mushrooms

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

• Nutritional powders and supplements

• Ready-to-eat meals and snacks

Products processed with the LG-125 retain excellent rehydration properties, long shelf life, and superior flavor and nutrition, making them ideal for premium retail, export markets, and functional foods.

Operating Instructions

1. Material Preparation
   Materials are washed, cut, and pre-treated according to product specifications.

2. Tray Loading and Freezing
   Product is loaded onto trays and frozen to below –25°C in a freezing tunnel or cold storage.

3. Vacuum Freeze Drying
   Frozen trays are placed into the drying chamber. The vacuum pump reduces chamber pressure while the condenser captures sublimated water vapor. Radiant heating plates provide gentle, uniform heat to sublimate ice into vapor without damaging the product.

4. Completion and Packaging
   After drying, sterile air or nitrogen restores atmospheric pressure. Dried products are removed, inspected, and packaged. Trays are cleaned and prepared for the next cycle.
