The Lyophilizer Manufacturing Experts
a wide range of industries including:
1.Laboratory Lyophilizers - remove water from delicate biological products without damaging their chemical structure.
2. Pilot Laboratory – operated via a PC control system parameters are monitored and stored during freeze drying to provide full documentation.
3. Pharmaceutical Lyophilizers / Biopharmaceutical Freeze Dryers– increase the shelf life of vaccines and antibodies, antibiotics, proteins, enzymes, hormones, viruses and bacteria, pathological samples and cultures
4. Food Preservation – a superior preservation method for a variety of foods such as fruits, vegetables, fish, culinary herbs, coffee, dairy products, instant noodles and soups
Industrial – large capacity for high volume of products including those for the aerospace industry
The Process:
First – gently freeze the product.
Second – a high-pressure vacuum is used to extract the existing solvents (such as water) in the form of vapor on a condenser below the freezing chamber which returns to ice and is removed.A rise in temperature then removes any remaining moisture in the product.
The Result – The products structure, size, nutrients, flavors and colors are preserved for storage or transport.
SUBLIMATION
Sublimation is when a solid (ice) changes directly to a vapor without first going through a liquid (water) phase. Thoroughly understanding the concept of sublimation is a key building block to gaining knowledge of freeze drying.
As shown below on the phase diagram for water, low pressures are required for sublimation to take place.
Sublimation is a phase change and heat energy must be added to the frozen product for it to occur.
Sublimation in the freeze drying process can be described simply as:
1. FREEZE - The product is completely frozen, usually in a vial, flask or tray.
2. VACUUM - The product is then placed under a deep vacuum, well below the triple point of water.
3. DRY – Heat energy is then added to the product causing the ice to sublime.
FREEZE DRYING EQUIPMENT
The main components of freeze drying equipment are:
- Refrigeration System
- Vacuum System
- Control System
- Product Chamber or Manifold
- Condenser
Features and Benefits:
1. Touch screen display, PID function adjust
2. Compound refrigeration technology, less frozen dry time.
Large freezing capacity and large water capture capacity.
3. The material is 304 stainless steel in side, to keep anti-
corrosion, strong and easy to clean.
4. Silicone oil frozen medium, the deviation is no more than
1℃, so drying uniformly.
5. The drying chamber's door is made of high transparent
and colorless transparent organic glass
6. Optional for in situ pre freezing
7. Optional temperature recorder, the adjustable temperature
record point and real-time monitoring
8. Optional eutectic point test device, and automatic pressure
plug device.
9. Square shelf is not easy deformation, easy operation and
cleaning.
