The freeze dryer uses thebest refrigeration system to freeze the product and condensate 

thesteam produced during freeze-drying procedure. Freeze-drying technologyrequires the refrigeration system to keep a low temperature status for a longperiod of time, therefore, the requirements to the refrigeration system arevery high. But the freeze dryer of our company can easily help you to reachyour goal.
■ Use world famous brand, e.g. Frascold, Danfoss, Copeland, Castel, Edwards,and etc.
■ The system uses double stage half sealed piston compressor to reach firstclass temperature reducing speed rate and the lowest temperature in China.
■ Power in the system is much greater than needed to efficiently ensure therefrigeration performance.
■ Digital and module design has a high protection to ensure the system to runnormally and stably.
■ The powerful refrigeration system, liquid spray cooling system and otherprotection installations keep to the best working temperature and highreliability for system.
■ The sensitive transducing system can provide alarm and protection in timeagainst abnormal running situation.
■ Uses refrigeration conforming to the world environment protectionrequirement, such as HCFCR22 and HFCRA for choice.
■ Special synthetic lubricating oil can eliminate various kinds of problem dueto high temperature of normal mineral oil.
The vacuum system of the freeze dryer providers a necessary pressureenvironment to freeze drying procedure. Cooperating with ice condenser, it canreach the vacuum level required by the freeze-drying procedure. To make thesystem run stably under high vacuum situation,the key point is the performanceof the vacuum pump, and the valve, seal and instrument that cooperate with thepump. 
The vacuum system of ourfreeze dryer has the following characteristics:
■ Standard configuration, uses Edwards double stage oil sealed rotary vanevacuum pump.
■ Option: Edwards pump
■ Equipped with two vacuum probes, for measuring the vacuum level of dryingchamber and pump respectively.
■ Option: condenser type vacuum meter.
■ There are two methods for controlling drying chamber vacuum level:
1. Control opening and closing of the air inlet valve, introduce the sterilizedair from sterilized room.
2. Control opening angle of main separated butterfly valve to reach the purposeof controlling the vacuum level.
Separated butterfly valve between drying chamber and ice condenser, circulationpump, spotlight and other components and etc. of the freeze drier, use thefirst class brands from other countries or from domestic factories. 
The above systems of ourfreeze dryer have the following characteristics:
■ A main separated butterfly valve or mushroom valve is equipped between thedrying chamber and ice condenser to keep a no leakage seal in both directions.
■ Use labial margin seal design to compensate the change of temperature andpressure during operation.
■ Eccentric valve rod and eccentric butterfly valve eliminate the wear-out ofupper and lower ends of valve seat during frequent opening.
■ May choose electric of pneumatic driving device.
■ Imported original electric driver can steplessly adjust the opening angle ofbutterfly valve, control the vacuum level of the drying chamber to avoid frombeing polluted.
■ Stainless steel valve body and TEF elastic valve seat conform with GMPspecification.
■ The drying chamber and ice condenser are equipped with sight glass. The sightglass can be equipped with spotlight to obtain clear monitoring.
■ Shelf refrigerating heating system uses Denmark Grundfos UPS circulationpump, Sweden plate type heat exchanger, The size of the exchanger is small,this reduces the heat conduction mediator and energy consumption, raises therefrigeration efficiency. 
The control system of the freeze dryer provides a reliable whole procedurecontrol for the freeze drier. It has advanced functions of display, control,recording, printing and alarming.
The control system of ourfreeze dryer has the following characteristics:
■ The mains air switch, transformer and AC contactor fixed in electric cabinetare Siemens products. The electric cabinet is secured on machine frame. Allmachine pump motors are equipped with overheat protection, solenoid valve andheating circuit are equipped with separate protection.
■ The display screen uses Mitsubishi touch screen, PLC, indicating light,sound-light alarming system, and etc.
■ Temperature measuring, pressure measuring, the components can work normallyunder high temperature, ultra-low temperature and high vacuum level with highreliability.
■ The control system can display the running status of all components of thewhole system, and can store and process the operation information and variousdata. It can provide procedure recording report of whole freeze-drying process.It can alarm on failure or abnormal situation, provide checking formaintenance, the operator can set and modify data and steps.
