The freeze drier uses the best 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, the requirements to the refrigeration system are very high. But the freeze drier of our company can easily help you to reach your 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 first class temperature reducing speed rate and the lowest temperature in China.

¬        The system power equipped is much greater than needed to efficiently ensure the refrigeration performance.

¬        Digital and module design has a high protection to ensure the system to run normally and stably.

¬        The powerful refrigeration system, liquid spray cooling system and other protection installations keep to the best working temperature and high system reliability.

¬        The sensitive transducing system can provide alarm and protection in time against abnormal running situation.

¬        Uses refrigeration conforming to the world environment protection requirement, such as HCFCR22 and HFCRA for choice.

¬        Special synthetic lubricating oil can eliminate various kinds of problem due to high temperature of normal mineral oil.

The vacuum system of the freeze drier providers a necessary pressure environment to freeze drying procedure. Cooperating with condenser, it can reach the vacuum leaver required by the freeze-drying procedure. To make the system run stably under high vacuum situation. The key point is the performance of the vacuum pump, and the valve, seal and instrument that cooperate with the pump.  

The vacuum system of our freeze drier has the following characteristic:

¬        Standard configuration, uses Edwards double stage oil sealing revolving plate pump.

¬        Option: Edwards pump

¬        Equipped with two vacuum probes, for measuring the vacuum level of freeze drying chest and pump respectively.

¬        Option: condenser type vacuum meter.

¬        There are two methods for drying chest vacuum level control:

1.        Drying chest vacuum level controls the opening and closing of the air inlet valve, introduce the sterilized air from sterilized room.

2.        Drying chest vacuum level controls the opening degree of the big butterfly valve to reach the purpose of controlling the vacuum level.

The drying chest and water capture valve, circulating pump, spotlight and etc. of the freeze drier, like other components of the freeze drier, use the first class components from other countries or from domestic factories.

The above systems of our freeze drier have the following characteristics:

¬        A couple-clamping butterfly valve is equipped between the drying chest and water capture to keep a no leakage seal in both dirctions.

¬        Use labial margin seal design to compensate the change of temperature and pressure during operation.

¬        Eccentric valve rod and eccentric butterfly valve eliminate the wear-out of upper and lower ends of valve seat during frequent opening.

¬        May choose electric of pneumatic driving device.

¬        Import original electric driver can stepless adjust the opening wideness of butterfly valve, control the vacuum level of the drying chest to avoid from being polluted.

¬        Stainless steel valve body and TEF elastic valve seat conform with GMP specification.

¬        The drying chest and water capturer are equipped with viewing glass. The viewing glass can be equipped with spotlight to obtain clear procedure monitoring.

Shelf refrigerating heating system uses Denmark Grundfos UPS circulation pump, Sweden plate type heat exchanger, The size of the exchanger is small, this reduces the heat conduction mediator and energy consumption, raises the refrigeration efficiency.
