Vacuum Freeze Dryer – Industrial Freeze Drying Solutions for Food, Pharma, and Health Products
HSYL offers advanced vacuum freeze drying equipment designed for vegetables, fruits, meat, beverages, dairy products, and more. Our systems integrate dual-trap condensation, uniform heating plates, continuous de-icing, and intelligent control to maximize efficiency and product quality.
Overview
The vacuum freeze dryer is widely used across food processing, pharmaceuticals, biotechnology, nutrition, and health product industries. Freeze drying preserves natural flavors, nutrients, and textures while extending shelf life. HSYL freeze dryers are designed to meet industrial-scale production requirements, offering high reliability, energy efficiency, and automation.
Freeze Drying Process Flow
- Raw Material Preparation: Clean, peel, slice, or cut fruits, vegetables, meat, or dairy products to uniform sizes for even drying.
- Pre-Freezing: Materials are pre-frozen to solidify water content, preventing cellular damage during drying.
- Loading: Pre-frozen materials are placed on anodized aviation aluminum heating plates inside the drying chamber.
- Vacuum Application: The chamber is evacuated to create a low-pressure environment, enabling sublimation.
- Primary Drying: Heat is applied through efficient heating plates. Ice sublimates directly into vapor, which is captured by the dual-trap condensation system.
- Secondary Drying: Residual moisture is removed to achieve target dryness, ensuring product stability.
- De-icing & Continuous Operation: Trap 1 melts accumulated ice while Trap 2 captures vapor, allowing uninterrupted operation.
- Unloading: Dried materials are automatically ejected, maintaining hygiene and minimizing manual handling.
- Packaging: Freeze-dried products are packed in moisture-proof containers, ready for storage or distribution.
Key Equipment Modules
- Drying Chamber: Equipped with anodized aviation aluminum heating plates for uniform heat transfer, optimized for high-efficiency sublimation.
- Dual Vapor Trap System: Trap 1 condenses ice while Trap 2 captures vapor, enabling continuous operation without downtime.
- Vacuum Pump & Control System: Creates precise low-pressure environment; intelligent PLC + HMI ensures stable performance and easy operation.
- Automatic De-icing: Continuous de-icing cycle prevents buildup and ensures consistent freeze drying quality.
- Material Handling: Food-grade trays, racks, and conveyors minimize contamination and simplify loading/unloading.
- Optional Add-ons: Temperature sensors, remote monitoring, and data logging for industrial-scale quality control and traceability.
