Design Features
- 2 chambers system meet maximum hygiene requirement.
- Rectangular drying chamber and ice condenser, high space using rate and high temperature uniformity.
- Isolation valve installs between chamber and condenser for pressure rise test, leak rate test and capable of automatic close once a power outage occurs.
- Delicate designed fluid circulates system guarantees uniform temperature of shelves and across the drying chamber.
- Adopt “internal welding” technology to ensure the flatness and air-tightness of shelves.
- Shelf slope temperature control.
- Hydraulic stoppering system with pressure monitoring and is adjustable to reduce vials breaking rate.
- Ice condenser coils surface area 1:1 comparing to the shelf.
- Automatic CIP/SIP process and semi-automatic CIP/SIP as per parameters setting.
- Drying chamber, ice condenser and all pipelines are under pressure vessel guidelines.
- All valves that use to isolate air and water are pneumatic operated, rapidly open/close and are capable of auto close once a power outage occurs.
- World top class components and international standard valves, pipes, flanges and sensors.
- Machine structure, functions and components brand can be customized.
- Quality and performance test before shipment.
- FDLS freeze dryers are easy to integrate with other equipment in production line.
Based on high advanced PLC and user-friendly touch screen HMI, to control all the machine functions, performs all interlock checks, and generate processes and device alarms. Capable of automatic execute the freeze drying steps you are programmed, monitoring system running status, protect your freeze dry system and raw product all the time.
The control system has been pre-programmed a bunch of protection logic such as: System auto shut down if chamber pressure not reduce; Vacuum pump will not active if condenser temperature not reach set to avoid vapor flows into vacuum pump and damage it; Once a failure appears, sound-light alarm and touch screen HMI shows possible failure reason, meanwhile, all air and water isolate valves auto close to maintain chamber pressure and protect your products.
The delicate designed LYO-MEGA V2.0 guarantees your drying data and drying steps that stored in HMI will not lose once a power outage, and the drying process will continue after power restoration. As well as, it supports operator modify the current-running freeze drying steps (while machine is in operation), system will auto execute the latest modified drying recipe.
The LYO-MEGA V2.0 interface functions:
- Graphic display main components working status and key parameters.
- System and key parts functional test.
- Automatic and semi-automatic work mode.
- Freeze drying recipes management.
- CIP/SIP control.
- Real-time freeze drying curve.
- Historical curve review.
- Drying data-logging and can be exported via USB.
- Users, password and authorizations.
- Sensors calibration.
- Alarms.
