Industrial large-scale LG50 50-square-meter freeze dryer

freeze dryer/ lyophilizer

As a flagship high-capacity solution for large-scale food processing, the LG50 50-square-meter freeze dryer integrates cutting-edge lyophilization technology, robust construction, and intelligent operation—designed to help food manufacturers, agricultural cooperatives, and export enterprises unlock efficiency, preserve quality, and gain competitive edges.

Core Specifications & Build Quality

At its core, the LG50 features a 50㎡ effective drying area, supporting 500–800kg of fresh food per batch (adjustable by product density). Crafted with food-grade 304 stainless steel, it meets FDA and CE certifications, ensuring compliance with global hygiene standards while resisting corrosion and enabling easy sanitization. The insulated drying chamber maintains stable low temperatures (-45℃) and high vacuum levels (1–5 Pa), laying the foundation for superior freeze-drying results.

Key Functions & Operational Efficiency

Equipped with an intelligent PLC touchscreen control system, the LG50 simplifies parameter adjustment—temperature, vacuum degree, drying time, and desorption cycles are precisely configurable, with real-time monitoring to avoid human error. Its three-stage lyophilization process (rapid freezing, sublimation, desorption) preserves the cellular structure of foods, locking in vitamins, minerals, and natural flavors that are often lost in heat drying. The final product achieves ≤3% moisture content, eliminating the need for chemical preservatives.

Practical Roles & Versatility

The LG50 excels across diverse food categories: fruits (strawberries, mangoes), vegetables (spinach, carrots), meats (chicken, beef), seafood (shrimp, fish), herbs, and dairy products. It transforms fresh ingredients into shelf-stable, ready-to-eat or rehydratable products—ideal for healthy snacks, baby food, emergency rations, or export-grade goods. By reducing product weight by 70–90%, it drastically cuts storage and transportation costs, a critical advantage for global trade.

Competitive Advantages & Value Proposition

Compared to traditional drying methods, the LG50 offers unmatched benefits: no nutrient degradation, no texture hardening, and 100% additive-free outputs that align with modern consumers’ demand for healthy food. Its high throughput meets large-scale production needs, while low energy consumption and durable build reduce long-term operational costs. For businesses, this translates to expanded product lines, higher profit margins, and access to premium markets that prioritize quality and safety.

Decision-Making Guide

If you’re scaling up food production, targeting export markets, or aiming to replace outdated drying equipment, the LG50 delivers immediate value: it solves the pain points of short shelf life, high logistics costs, and compromised quality. Backed by reliable performance and global certifications, it’s a low-risk investment that drives sustainable growth in the competitive food industry.
