Vacuum And Hydraulic System of Lyophilization Equipment

Ώρα: 2019-07-08

The moisture in the product can be sublimated quickly only under vacuum to achieve the purpose of drying. The vacuum system of Lyophilization Equipment consists of a freeze-drying box, a condenser, a vacuum valve, a vacuum pump, a vacuum line, and a vacuum measuring component.

The system of Lyophilization Equipment uses a vacuum pump set to form a powerful suction capacity, forming a vacuum in the drying chamber and the condenser, on the one hand, causing the water in the drying chamber to evaporate under vacuum. The vacuum degree of the vacuum system should match the sublimation temperature of the product and the temperature of the condenser. If the degree of vacuum is too high or too low, it is not conducive to sublimation. The vacuum degree of the drying box should be controlled within the set range. Shortening the sublimation cycle of the product, the premise of vacuum control is that the vacuum system itself must have a small leakage rate. The vacuum pump has a large enough power reserve to ensure that the ultimate vacuum is reached.

The hydraulic system of Lyophilization Equipment is a special device that presses the stopper into the bottle mouth at the end of freeze drying. The hydraulic system is located at the top of the drying box and is mainly composed of an electric motor, an oil pump, a check valve, a relief valve, a solenoid valve, a fuel tank, a cylinder and a pipe.

Στο τέλος της Λυοφιλοποίησης, το υδραυλικό σύστημα απόφραξης αρχίζει να λειτουργεί και υπό συνθήκες κενού, το επάνω ράφι μετακινείται αργά προς τα κάτω για να ολοκληρωθεί η εργασία πώματος φιάλης προϊόντος. Το αντλιοστάσιο υδραυλικού λαδιού, ο κύλινδρος λαδιού κ.λπ. είναι εγκατεστημένα στο πάνω μέρος της δεξαμενής λυοφιλοποίησης. Κάτω από την κίνηση του σταθμού υδραυλικής αντλίας, το στρώμα πλάκας ανυψώνεται πάνω και κάτω στη δεξαμενή για να διευκολύνει την είσοδο και την έξοδο της δεξαμενής και τις εργασίες καθαρισμού.

The seal of the lower part of the piston rod of the cylinder uses O-type silicon. The rubber seal ensures that oil will not be contaminated and the drug will be contaminated. The piston uses a YX polyurethane seal. The electromagnetic reversing valve and the hydraulic balancing valve are accurate in signal transmission, and do not slip without vibration.
