The freeze dryer made by our company is designed and manufactured strictly according to GMP Specifications,and has the following merits:
All the parts contacting the products are made of stainless steel 316L,the surface roughness reaches Ra≤0.5um. The inner circle of the chamber has a smooth transition without dead corner,no objects accumulated. Considering for user,the structure is easy to clean. Option for steam sterilization or chemical sterilization. Except for the above,our company can also provide automatic running CIP(Clean-in-Place)and SIP(Sterilization-in-Place)functions to ensure the high quality of cleaning and sterilizing the equipment. SIP: Use overheats pure steam(121℃) Equipped with cooling water jacket,after sterilizing,it can fast reduce the temperature of the chamber(if less than 20m²,the equipment is standard configuration.) Optional pneumatic door lock,it locks automatically. Use imported sterilization filter to ensure absolutely sterilized air entering equipment. The chamber and various kinds of container and tube are all wrapped with imported insulation material to efficiently avoid from heat transmission. Can carry out constant humidity control to the refrigeration humidity. Equipped with water ring pump capable to eliminate residual water inside the chamber. CIP: High pressure clean water thoroughly wash inner surface of the chamber and ice condenser. Equipped with large flux CIP pump. Fixed with CIP tubing that automatically drains the residual water. Use rotary fixed nozzles with 360 angle spraying. The hydraulic rod in hydraulic system adopts bellows to prevent oil from leaking and product can be protected. The freeze dryer made by our company has a proper layout and enough space to benefit the maintenance and operation of the equipment. Rectangular or cylinder shape drying chamber(user may choose one of them) Horizontal of vertical ice condenser Intefrak design can fully use space. Separated design can make each component independent,easy to operate and maintain. Working temperature scope of ice condenser:-8℃(when it is dry)-+121℃(when in steam sterilizing). Pressure scope of the chamber:1Pa Use industrial preesure vessel standard:GB150-1998 series. Conform to national vacuum equioment standard:GB/T3163-3164 Standard of international Electrotechnical Commission(IEC) China Electric Equipment Standard(GB) The drying chamber,shelf and ice condenser is made of stainless steel 316L. TIG welding avoids gap that can not be cleaned and possible leakage. The welding point the tube is photographed with X-ray,with inspection record and certification of qualification. The roughness of inner surface reaches Ra≤0.5um,mirror polished. Leakafe rate of the system≤5*10-2mbar I/sec to ensure normal and reliable running. There is no dead corner in the chamber,the connection of tube is simple and reasonable,east to clean. The freeze dryer uses the best refrigeration system to freeze the product and condensate the steam produced druing freeze-drying procedure.Frezzez-drying technology requires the refrigeration system to keep a low temperature status for a long period of time,therefore,the requirements to the refrugeration systemm are very high.But the freeze dryer of our compant can easily help you reach your goal. Use world famous brand,e.g.Frascold,Danfoss,Copeland,Castel,Edwards,and etc. The system uses double stage haof sealed piston compressor to reach first class temperature reducing speed rate and the loweast temperature in China. Power in the system is much greater than needed to efficiently ensure tehe refrigeration performance. Digital and module design has a high protection to ensure he system to run normally and stably. The powerful refrigeration system,liquid spray cooling system and other protection installations keep the best working temperature and high reliability for system. The sensitive transducing system can provied alarm and protection in time against abnormal running sityation. 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 dryer providers a necessary pressure environment to freeze drying procedure.Cooperating with ice condenser,it can reach the vacuum level required by the freeze-drying procedure.Cooperating with ice condenser,it can reach the vacuum level 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 dryer has the following characteristic: Standard con figuration,uses Edwards double stage oil sealed rotary vane vacuum pump. Option:Edwards pump.Equipped with two vacuum probes,for measuring the vacuum level of drying chamber and pump respectively. Option:condenser type vacuum meter.
