BOTH SFD Series 1kg-100Kg Lyophilizer Vacuum Automatic Fruit/Vegetables/liquid/Herb/Pet Food Freeze Dryer Machine
Vacuum Freeze-drying Technology, also known as sublimation drying, is a method of pre-freezing materials and sublimating their moisture under vacuum. The original biological and chemical properties of freeze-dried materials are basically unchanged, and they are easy to be stored for a long time. After rehydration, the freeze-dried material can be restored to the state before freeze-drying and maintain the original biochemical properties. Therefore, the Vacuum Freeze-drying Technology is widely used in pharmaceutical, food, chemical, biological products and other fields.
① Vacuum Gauge:The high accuracy and extended lifespan of the Pirani vacuum gauge ensure a stable vacuum environment, eliminating fluctuations associated with traditional mechanical gauges.
② Cold Trap Coil Design: Our unique flat-shaped design increases the contact area with the chamber, resulting in superior heat exchange efficiency and freezing performance.
③ Expansion Valve Design:Compared to other household freeze dryers, the expansion valve design contributes to more stable temperature and pressure control while enabling regulation of refrigerant flow,enhancing freeze-drying efficiency.
④ Temperature Probe Design:Placing the temperature probe at the midpoint of the coil enables more precise cold trap temperature control. This approach, as opposed to the traditional placement at the compressor outlet used by some manufacturers, improves overall equipment efficiency and safety
True-Color Industrial Touchscreen
4.3-inch touchscreen provides an intuitive and
user-friendly interface, allowing real-time monitoring
of key drying parameters.
Aircraft-Grade Acrylic Door
Transparent yet durable, enabling easy observation of material
changes during the drying process.
Teflon-coated aluminum partition
Ensures uniform freezing effect of materials and meets
food-grade requirements at the same time. The coating is non-stick, corrosion-resistant, heat-resistant, easy to clean and extends the service life
High-Performance Silicone Seals
Maintains a stable seal in extreme temperatures ranging from
-60°C to +200°C.
Premium Compressor Brands
Equipped with renowned compressors from Germany, Brazil, and France, ensuring stable refrigeration and long-lasting performance.
