Vacuum freeze drying, also known as lyophilization, is a cutting-edge dehydration technology that removes moisture from materials by sublimation under vacuum conditions. This process preserves the original structure, flavor, nutritional value, and biochemical properties of products, making vacuum freeze dryers indispensable in pharmaceutical, food processing, biotechnology, and chemical industries.
Shanghai Lantai, as a leading freeze dryer supplier, leverages decades of microwave equipment expertise to provide state-of-the-art vacuum freeze dryers that combine precision engineering, reliable performance, and user-friendly operation.
Standard vacuum freeze dryers are designed for bulk drying of solids, liquids, and powders. They feature spacious drying chambers with multiple shelves or trays, allowing simultaneous processing of large quantities. These models are widely used in pharmaceuticals for vaccine preservation, in food industries for fruit and vegetable drying, and in chemical labs for sensitive compound dehydration.
Key features include:
- High-capacity cold traps reaching temperatures as low as -80°C to capture moisture efficiently.
- Precise vacuum control systems maintaining pressures below 5 Pa for optimal sublimation.
- Adjustable shelf temperatures ranging from -50°C to +70°C to accommodate various product requirements.
- Durable stainless steel construction for hygiene and long service life.
- Digital control interfaces with programmable freeze-drying curves for repeatable results.
As a freeze dryer supplier, Shanghai Lantai ensures these standard models meet rigorous industrial standards, offering excellent value for medium to large-scale operations.
Multi-manifold vacuum freeze dryers are specialized units designed for drying multiple samples simultaneously, often used in laboratory and research settings. Their unique manifold system allows connection of several flasks or containers, enabling high-throughput freeze drying with consistent quality.
Advantages include:
- Efficient drying of small batches or experimental samples without cross-contamination.
- Flexibility in sample size and shape due to manifold design.
- Enhanced vacuum sealing and nitrogen gas filling options to protect sensitive materials.
- Ideal for biological, pharmaceutical, and chemical research applications.
Shanghai Lantai, as a reliable freeze dryer supplier, offers multi-manifold models with advanced PLC control systems and real-time data monitoring, facilitating precise process management.
For small businesses, home use, or specialty food preservation, Shanghai Lantai provides compact vacuum freeze dryers that deliver professional-grade freeze drying in a smaller footprint. These models are perfect for freeze drying fruits, vegetables, herbs, pet food, and even meals, preserving taste and nutrients effectively.
Features include:
- User-friendly interfaces with preset programs suitable for common food items.
- Integrated vacuum pumps and refrigeration systems optimized for energy efficiency.
- Portable designs that fit easily into kitchens or small workshops.
- Affordable pricing without compromising on freeze drying quality.
As a freeze dryer supplier committed to diverse customer needs, Shanghai Lantai's household models empower entrepreneurs and hobbyists to access premium freeze drying technology.
Top press vacuum freeze dryers incorporate advanced pressing technology that enhances drying uniformity and efficiency. By applying controlled pressure during the freeze drying process, these models improve heat transfer and reduce drying time, making them suitable for high-precision pharmaceutical and biotech applications.
Key characteristics:
- Automated top press mechanism ensuring consistent sample compression.
- Sophisticated vacuum and temperature control systems for delicate materials.
- Capability to handle both bulk and manifold-type drying.
- Optional defrost and eutectic point testing functions for process optimization.
Shanghai Lantai, as a leading freeze dryer supplier, integrates these features into their top press models, delivering superior performance for demanding industrial processes.
