FD Series Vacuum Freeze Dryer(Lyophilizer)
FD Series Vacuum Freeze Dryer(Lyophilizer)
1. The vacuum freeze drying is an advanced method for the material for the material dewatering. It freezes the moisture material in the low temperature and makes the water inside sublimate directly in the vacuum condition. Then it collects the sublimated vapor by means of the condensing way so as to dewater and dry the material.
2. Being processed by the vacuum freeze drying, the physical, chemical and biological states of the material are basically unchanged. The volatile and nutritious contents in the material, which are easy to be denatured in a warm condition, will be lost a little. When the material is freezing dried, it will be formed into a porous one and its volume be basically the same to that before drying. Therefore, the processed material can be recovered quickly if being watered agfgain, because of its large contacting area and it can be stored for a long period in a sealed vessel.
3. The vacuum freezing dryer can be widely used for the research and production of various heat-sensitive biological products such as vaccine, biological product, medication, vegetable vacuum packing, snake power, turtle capsule and so on.
With the development of the biological, pharmaceutical, food and health are product industries, the vacuum freezing dryer is a necessary equipment in the research institutes and companies in such industries.
4. For our vacuum freeze dryer, it divides into two types based on the usage: Food type(round shape) and Pharmaceutic type (rectangular shape).

Features
1. Designed and manufactured based on GMP requirement, FD vacuum freezing dryer adopts a solid construction with a small occupied area and convenient installation and transportation.
2. Its operation can be controlled by hand, automatic program or computer. It will be more reliable if being equipped with the antijamming unit.
3. The metal components as the case, plate, vapor condenser, vacuum pipeline and hydraulic device and all made of stainless steel.
4. Since the shelf is equipped with an advantageous stopped automatically in a bacteria-free condition so as to decrease the labor intensity and increase the product quality.
5. Adopting the indirect freezing and heating, the shelf is equipped with a high-efficiency heat exchanger in order reduce the temperature different between plates.
6. The refrigerating system adopts the Semi-closed compressor imported from USA. The key components such as the medium refrigerator, solenoid valve, expansion valve and oil distributor are also purchased from world-famous companies as to ensure the cooling temperature ,improved the reliability and lower energy of the whole machine m is the domestic first-class energy -saving product.
7. The vacuum, temperature, product resistance, water interruption, power interrupting, automatic over temperature alarming and automatic protection are all displayed by the digital control instrument.
8. The visual-type horizontal water collector can absolutely prohibit and fault operation. Its collecting capacity is 1.5 times of that of similar collectors.
9. The air valve can be closed or opened automatically. The protection for water and power interruptions is also equipped.
10. The relevant freeze drying curve can be supplied to customers.
With the help of the advanced drying case exhaust device, the water ratio of products can be lower than 1%.
11. The SIP steam sterilizing system or CIP automatic spraying can also be attached bassed on the customer requirement.
12. Electric control unit has advanced measure system which can guarantee the quality of products.
13. The material of drying box, condensator, evaporator, vacuum tube is stainless steel according to the requirement of GMP.
14. The refrigeration system is unipolar or bipolar which can rach the perfect low temperature and can be conveniently operated and repaired.
15. The vacuum system is bipolar which can keep products in the best vacuum condition in order to have the drying process in a shorter term.
16. An all-round service including the satisfied after-sale service, installing, setting-up .repairing and technical training is committed.

Application
Food industry:
Vacuum freeze dryer can be used in the drying vegetables, meet, fish, condiment instant food and specialty etc, keeping the food’s original fresh look, smell, taste, shape. The freeze-dryed products can regain water competently and can be easily longer stored and less-costly transportation.
Nutrition and health care industry:
Vacuum freeze-dryed nurture products such as royal jelly, ginseng, turtle terrapin, earthworms etc are more natural and original.
Pharmaceutical industry:
Vacuum freeze dryer can be used in the drying of chinese and western medicine such as blood serum, blood plasma, bacterin, enzyme, antibiotics, hormone etc.
Biomedicine research:
Vacuum freeze dryer can long-term store blood, bacteria, arter, bones, skin, cornea, nerve tissue and organs etc which can regain water and rebirth competently.
Others:
Producing adiabatic ceramic in space industry; storing of spcimens and relic in archaeological industry.
