10×LG-200 Vacuum Freeze-drying equipment – Industrial-Scale Freeze Dryer

Introduction

The 10×LG-200 Vacuum freeze-drying equipment is a state-of-the-art industrial freeze dryer designed for large-scale food processing, agricultural products, and high-value nutritional ingredients. Manufactured by Shenyang Aerospace Xinyang Quick-Frozen Equipment Manufacturing Co., Ltd., this system integrates decades of aerospace-derived technology and advanced food processing expertise, ensuring maximum efficiency, product quality, and reliability.

Freeze-drying, also known as lyophilization, is a dehydration process that removes moisture from frozen products under high vacuum conditions. Unlike traditional drying methods, freeze drying allows water in the product to sublimate directly from ice to vapor, preserving the natural shape, color, texture, aroma, and nutrients. The 10×LG-200 system is ideal for industrial-scale operations where consistent quality and high throughput are essential.

System Overview

The 10×LG-200 Vacuum Freeze Dryer consists of ten LG-200 drying chambers, each with its own:

• High-efficiency condenser (cold trap)

• Advanced vacuum system

• Radiant heating plate assembly

• Intelligent automatic control system

This modular configuration allows flexible production scheduling. While some chambers are in operation, others can undergo maintenance or cleaning, enabling continuous processing without production downtime. The system is designed to meet the growing demands of the global freeze-dried food market, providing reliable performance for export-oriented and high-volume production facilities.

Key Technical Specifications

The 10×LG-200 system is engineered for performance and efficiency. Typical specifications include:

The system features high water vapor capture efficiency, precise temperature control, and stable vacuum maintenance, ensuring uniform drying and optimal product quality across all ten chambers.

Applications

The 10×LG-200 vacuum freeze dryer is suitable for a wide range of industries and products, including:

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

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

• Instant foods: soups, noodles, ready-to-eat meals

• Premium pet foods and snacks

• Herbal extracts and medicinal plants

• Nutritional and health foods

Freeze-dried products retain excellent rehydration properties, lightweight packaging, and long shelf life, making them ideal for export, emergency food, outdoor meals, and high-end snacks.

Operating Instructions

The 10×LG-200 system is designed for safe, efficient, and automated operation. A typical freeze-drying cycle includes the following stages:

1. Raw Material Preparation

Products are cleaned, cut, and pre-processed according to the required specifications. Proper pre-treatment ensures uniform drying and high-quality final products.

2. Tray Loading and Freezing

Prepared materials are evenly loaded onto trays and placed on product carts. The carts are then moved into a freezing tunnel or cold storage, where temperatures are lowered to –25°C or below, ensuring complete freezing before drying.

3. Vacuum Freeze-Drying

Frozen carts are transferred into the drying chambers. After sealing the doors, the vacuum system quickly lowers chamber pressure while the cold trap condenses sublimated water vapor into ice. Radiant heating plates gently supply controlled heat to sublimate ice into vapor without damaging the product structure.

4. Drying Completion and Unloading

After the cycle, sterile air or nitrogen is introduced to normalize chamber pressure. The door is opened, and dried products are removed for inspection and packaging. Empty trays are cleaned and returned to the loading area for the next production cycle.
