As indicated in previous session the product is frozen in small amounts inside the ice condenser chamber single chamber method or separately in a deepfreeze unit in the lab area dual chamber methodAs a rule freezing takes place at atmospheric pressure similar to a conventional freezer.

Drying the product in roundbottom flasks or closeable widemouth filters is popular and has the advantage of being able to place or remove these containers separately in the freezedryer without disturbing the drying process for the other bottlesAs will be explained later on the thickness that is so important for the drying time in this area of application can be significantly reduced by freezing under rotation as opposed to conventional static freezingTaking advantage of centrifugal force a uniform ice layer is produced on the cylindrical wall of the glass container.

During primary drying the frozen water or solvent is removed as vapor from the product to be dried by means of sublimationThe vapor is transported out of the product due to the differential pressure and temperature in the chamber to the surface of the ice condenser and is desublimated at the cold ice condenser.

For another embodiment the inspection window comprises a reduced transmissibility for radiation in a frequency range of 500 MHz 1800 MHz andor 1900 MHz which also covers deviations from the afore mentioned frequencies of ±5 ±10 or ±20A reduction of the to transmissibility for radiation in this frequency region has shown to be very effective for increasing the electromagnetic compatibility in particular in connection with cell phones or transmitters in the radio technology located in the neighborhood of the freeze dryer.

For one embodiment of the inventive freeze dryer it is possible that the freeze drying conditions of the products are homogenized to a larger extent a propagation of an electromagnetic stimulation of a sensor andor a propagation of an electromagnetic measurement signal in the freeze dryer is improved andor the electromagnetic compatibility of the freeze dryer is improved.

From Martin Christ we offer freeze dryers for lab pilot and production and vacuum centrifuges for virtually all tasks and purposesIn the range we have freezer dryers with ice condensers from 2 to 800 liters and temperatures down to 105 176 CWe offer individual solutions and we can help you with both the preparation of requirements specifications and the subsequent qualification.

In parallel with the freezing process the device should run through what is called a warmup cooldown phase the vacuum pump can then warm up by running against the closed pressure control valve which improves its performance and its resistance to water vaporAt the same time the ice condenser is prechilled in order to be able to separate out the water vapor produced in the next step primary dryingThe preparation phase should last between 15 and 30 minutes.

Martin Christ Freezedryer structureThe basic components of a freezedrying system are Vacuum drying chamberVacuum pump for evacuating air from the drying chamber gas pump and regulating the drying vacuum with a pressure control valve.

Our wide range of models covers product capacities from 4 kg to 16 kg per drying cycleThe temperaturecontrolled shelves for your product are sized between 0.

Pilot freezedryers are devices for process optimisation or small batch production in flasks vials or product trays.

Prior to loading a new product the freezedrying system must be dry and any residual water from the previous run must be removed from the ice condenser chamberThe drain valve for emptying the ice condenser and the ventilation valve for venting the product chamber when the freezedrying process is complete are then closedThe product should not be more than 1–2 cm thick as otherwise the drying time will be excessively long.

The invention relates to a freeze dryerFurthermore the invention relates to a new use of a material.

This procedure reduces the layer thickness and thereby the total drying time will be shortened to a considerable extent see figures on the right sideTranslation of the original operating manual.

To start the sublimation process the pressure control valve to the vacuum pump is opened so that a vacuum is applied to the freezedryer.

With separate freezing it is helpful to prechill the shelves especially for small volumes of product in order to avoid partial thawing during transport to the freezedryer and evacuation.
