  • At least one port defining an opening is in communication with the second portion of the interior volume.
  • the container additionally allows to measure a temperature in immediate vicinity to the material during freeze-drying. Further advantages are addressed in the following.
  • An embodiment of the invention is a drying bag for drying a biological or pharmaceutical material, which comprises a bag shell having a bag shell outer site, a bag shell inner site, a bag interior cavity and a bag shell access opening, which reaches from the bag shell outer site to the bag shell inner site, a closable bag access opening, which provides an access to the bag interior cavity via the bag shell access opening, a double fixation tensioning belt, which is connected to the bag shell outer site at a tensioning-belt-bag-shell connection point, and which includes two free tensioning belt ends, which are arranged opposite to each other, each of the two free tensioning belt ends includes a tensioning belt fastening element, which allows a detachable connection of the free tensioning belt end at a supporting tub anchor for the tensioning belt fastening element, which is attached at a supporting tub, wherein the bag shell is partly made of a pliable first plastic foil and partly made of a vapor permeable sheet, the tensioning belt fastening elements, when the drying bag is positioned
  • An advantage of the bag shell being partly made by the pliable first plastic foil is that the bag shell can be stored in a flat, volume-reduced geometrical form prior to a positioning in the supporting bag.
  • the pliability of the first plastic foil allows further that the part of the bag shell, which is made of the first plastic foil, is in principle able to nestle to involved geometrical boundaries of the supporting tub once positioned in the supporting tub.
  • a large zone, preferably also additionally a homogenous zone, of mechanical contact of the involved geometrical boundaries of the supporting tub to the bag shell outer site provides a larger, preferably additionally also homogenous, heat transfer rate versus a scenario of an interrupted contact caused by gas spaces. Since drying occurs under reduced pressure, especially in case of freeze-drying of a very low pressure, the gas spaces will tend to become vacuum-type isolations. These hinder a heat transfer, which enables a rewarming of the material to be dried, which itself is cooled down during drying by an evaporation of volatile components contained in the material to be dried.
  • the efficient transmission of the supporting power by the supporting tub allows from the viewpoint of mechanical stability of the bag shell also to choose a relatively thin pliable first plastic foil, which favors again the heat transfer.
  • the tub function of the supporting tub provides a safety measure in case of an accidental leakage at the bag shell by collecting escaping material to be dried and thus avoiding a spilling into a drying chamber. Accordingly, a thickness of the pliable first plastic foil requires less security surcharge against an accidental leakage.
  • the addressed involved geometrical boundaries of the supporting tub are typically a planar bottom of the supporting tub, which is particularly relevant for the heat transfer, and side walls of the supporting tub, which are particularly relevant for the mechanical stability once the material to be dried is filled into the bag interior cavity.
  • the pliable first plastic foil is the intended primary contact area of the material to be dried during filling of the bag interior cavity, typically only to a part of its bag interior cavity volume, for example 50 volume percent thereof, once the drying bag is positioned in the supporting tub. This applies similarly during drying.
  • Intended primary contact area means that there might be some unintended spattering of the material to be dried during filling or drying, which thus leads to some unintended contact with the vapor permeable sheet or the parts of the bag access opening or a lid closing the bag access opening, which are directly facing the material to be dried. Accordingly, a contact of the material to be dried with the supporting tub respectively a material of the supporting tub at the contact is avoided. This is for example of relevance if the material of the supporting tub is a metal.
  • the dried material is often obtained in a physical form of a voluminous powder, which has partly formed larger but mechanically instable clumps or even one mechanically instable aggregate.
  • the pliable first plastic foil not only allows that the bag shell is stored in the flat, volume-reduced geometrical form prior to a positioning in the supporting tub. It also allows that the bag shell respectively the drying bag, which is filled with the dried material in a voluminous, but aggregated form is comminuted into smaller aggregates without a need to open the closed drying bag. This might be done for example by bending back and forth or of the closed drying back filled with dried material or by squeezing it together.
  • the pliable first plastic foil itself is for example made of polypropylene or polyethylene.
  • An advantage of the bag shell being partly made of the vapor permeable sheet is a possibility of a transfer of evaporated gaseous components of the material to be dried from the bag interior cavity to a drying chamber during drying despite of the bag access opening being closed. Without the possibility of the transfer, the volume of the interior bag cavity would increase in case of an application of a reduced pressure in the drying chamber up to a breakage of the bag shell.
  • the vapor permeable sheet is often less pliable than the first plastic foil, particularly if the vapor permeable sheet is a two-sided laminate or composite material comprising on one side a spined layer, which is plastic-weldable with the pliable first plastic foil.
  • the vapor permeable sheet contains for example a membrane layer of polytetrafluoroethylene, including expanded polytetrafluoroethylene, or polyethylene terephthalate.
  • the membrane layer has in case of a polytetrafluoroethylene membrane for example a pore size of 1 to 2 micrometers and in case of a polyethylene terephthalate) membrane a pore size of 7 micrometers.
  • the vapor permeable sheet is for example a composite membrane material, which comprises a membrane layer and a support layer.
  • the vapor permeable sheet is for example an expanded polytetrafluoroethylene membrane on a polyethylene support layer or an expanded polytetrafluoroethylene membrane on a polypropylene support layer.
  • the permeability of a given vapor permeable sheet may differ for different evaporated gaseous components of a material to be dried.
  • a vapor permeable sheet which allows a passage of at least 10 L, preferably at least 50 L, of air per minute and dm 2 of membrane area at a transmembrane pressure of 200 Pa (> 10 L air /min /dm 2 , preferably > 50 L air /min /dm 2 ) is deemed suitable for use in the bag shell for an efficient passage of for example water vapor.
  • the vapor permeable sheet is a vapor permeable sheet with a passage of at least 10 L, more preferably at least 50 L, of air per minute and dm 2 of membrane area at a transmembrane pressure of 200 Pa (> 10 L air /min /dm 2 , preferably > 50 L air /min /dm 2 ).
  • first-plastic-foil-to-sheet connection point a surface zone of the pliable first plastic foil is overlayed to a surface zone of the vapor permeable sheet and both zones are connected. Both zones are opposite to each other and are put together to form together a first-plastic-foil-to-sheet connection point.
  • the connection is typically tight for the material to be dried, the gaseous evaporated components of the material to be dried and the dried material.
  • connection is for example conducted by plastic welding, if the pliable first plastic foil and at least one side of the vapor permeable sheet can be plastic-welded with each other.
  • a suitable glue is an option, if the glue is inert at least for the time and under the conditions of drying against the material to be dried, the gaseous evaporated components of the material to be dried and the dried material.
  • Another possibility is that both zones are sufficiently pressed together to be tight, and the pressing is achieved by a mechanical device, for example a series of small clamps or staples or a sewing seam.
  • the connection is conducted by plastic welding.
  • the vapor permeable sheet at the first-plastic-foil-to- sheet connection point is directed towards the bag interior cavity and the pliable first plastic foil is at the first-plastic-foil-to-sheet connection point is directed away from the bag interior cavity toward the surroundings.
  • This arrangement is of advantage in case of a two-sidedness of the vapor permeable sheet with only one site available for plastic welding with the pliable first plastic foil, because it allows that the plastic welding itself is conducted by the plastic welding energy apparatus being applied from the bag shell outer site.
  • the pliable first plastic foil and the vapor permeable sheet are connected at a first-plastic-foil-to-sheet connection point and the pliable first plastic foil and the vapor permeable sheet are connected by plastic welding.
  • An advantage of the double fixation tensioning belt is a maintenance of a high volume of the bag interior cavity, when the drying bag is positioned for drying in the supporting tub and thus the drying bag is unfolded and erected. This applies for an empty unfolded and erected drying bag as well as for an unfolded and erected drying bag, which is filled with the material to be dried.
  • the fixation by the double fixation tensioning belt helps further to avoid wrinkles in the bag shell, especially where the bag shell is made of the pliable first plastic foil.
  • a suitable number of tensioning belts depends on the dimensions and the geometric shape of the bag shell at its maximum volume of the bag interior cavity.
  • One or two or more double fixation tensioning belts are possible at the drying bag, for example one, two, three, four, five or six double fixation tensioning belts, preferably one, two, three, four or five, more preferably two, three or four.
  • An intrinsic property of a belt is its pliability, which contrasts with a stiffness of a stick. Accordingly, a belt, e.g., the double fixation tensioning belt, does not hinder as much as a stick, when the drying bag is to be stored in a flat, volume-reduced geometrical form prior to a positioning in the supporting bag.
  • a stick can be designed to be removable from the drying bag and thus can be separately stored from the drying bag prior to a positioning in the supporting tub.

  • the double fixation tensioning belt is for example made of a second plastic, preferably made of a second plastic foil, more preferably made of a pliable second plastic foil.

  • the connection is for example conducted by plastic welding. It is understood that for plastic welding, the material of the bag shell outer site at the connection point and the material of the tensioning belt at the connection point must be suitable to be plastic-welded with each other.
  • the double fixation of the double fixation tensioning belt allows that the double tensioning belt is stretched between two supporting tub anchors for the tensioning belt fastening elements, particularly if the two supporting tub anchors for the tensioning belt fastening elements are arranged opposite to each other at the supporting tub.
