Freeze Drying Machine

Freeze Drying Machine

Freeze Drying Machine
Model: GZL
The freeze drier of our company is designed and manufactured according to GMP specifications, with the following characteristics:
The parts contacting the products are made of ALSL 316L stainless steel.
The surface roughness reaches R a≤0.5u m.
The inner circle of the chest has a smooth transition without dead corner, easy to clean.
Steam sterilization and chemical sterilization are optional.
In order to get better cleaning and the sterilization of the equipment, our company also provides automatic running CIP (on-site cleaning) and SIP (steam sterilization) functions.
SIP:
Use overheated pure steam (121℃).
Adopting cooling water jacket, it can quickly reduce the temperature of the chest after sterilizing. (if less than 20, the equipment is standard configuration.)
Optional pneumatic door lock for automatic locking
Use imported sterilization filter to ensure that the air coming into equipment is absolutely sterilized.
The chest and various kinds of container and tube are all wrapped with imported insulating layer to avoid heat transmission.
Can perform constant humidity control to the refrigeration humidity.
Water circulation pump is equipped to eliminate residual water in sterilization layer.
CIP:
The inner surface of the chest and condenser can be thoroughly washed by high- pressure clean water.
Equip large flow rate CIP pump. 
Fixed with CIP tubing to drain the residual water automatically.
Use rotary fixed nozzle with 360-degree spray.
The hydraulic system adopts isolated retractable corrugated tube.
Reasonable layout of our freeze drying machine makes it easy to maintain and operate.
Square or round shape chest for option
Horizontal or vertical condenser
Integral design makes the best use of space.
Due to separate design, the components are independent for easier operation and maintenance.
Working temperature scope of condenser: -8℃(when it is dry)~+121℃(when in steam sterilizing).
Pressure scope of the chest: 1Pa
Use industrial pressure container standard: GB150-1998 series.
Conform to national vacuum equipment standard: GB/T3163-3164
GMP and FDA relevant regulations.
Standard of international Electrotechnical Commission (IEC)
China Electric Equipment Standard(GB)
Material of chest, lamellar and condenser: AISI316L stainless steel.
TIG welding avoids gap that is difficult to clean and easy to leak.
The welding point of the tube is photographed with X-ray, with inspection record and qualification certification.
The roughness of inner surface reaches R a≤0.5u, mirror polished.
Low leakage rate of the system (≤ 5*10(-2) mbar 1/s) for reliable running.
No dead corner in the chest for easy cleaning
Refrigeration system
Our freeze drying machine uses reliable refrigeration system to freeze the product and condensate the steam produced during freeze-drying procedure. Freeze-drying technology requires the refrigeration system to keep a low temperature status for a long period of time, therefore, a good refrigeration system is needed to achieve this. As an experienced freeze drier manufacturer in China, we only use top grade refrigeration system.
The characteristics of this system include
Use world famous brand, e.g. Frascold, Danfoss, Copeland, Castel, Edwards, and etc.
Double stage half sealed piston compressor is utilized to reach first-class temperature reducing speed rate and super-low temperature.
Greater system power for superior refrigeration performance.
Digital and module design provides good protection function, so as to ensure the smooth running of the system.
The powerful refrigeration system, liquid spray cooling system and other protection installations guarantee the best working temperature and high system reliability.
The sensitive transducing system gives alarm and protection in time in case of abnormal running situation.
Use refrigeration conforming to the world environment protection requirement, such as HCFCR22 and HFCRA.
Special synthetic lubricating oil can eliminate the problems caused by high temperature of normal mineral oil.  
Vacuum system
The vacuum system of the freeze drying machine provides a necessary pressure environment to freeze drying procedure. Cooperating with condenser, it is able to achieve the vacuum level required by the freeze-drying procedure. In order to make the system run stably under high vacuum situation, high performance vacuum pump, valve, etc. are required.
