摘要： The invention relates to a method of producing aerogels and to an apparatus for carrying out the method. The aerogels are produced semi-continuously by per se known methods in that, following gel formation, the lyogel is transferred to a mobile container for at least two further procedural steps, the container comprising inlets and outlets and in that for these procedural steps, the container is moved to appropriate stations for the supply and discharge of materials, at which stations it is connected to feed and discharge means and in that the procedural steps are carried out there. An apparatus for carrying out the method comprises a container with a container top part and container bottom part, an encircling seal and a bag adapted to be placed into the container, the bag being connected along the opening and at least partially to thickening elements, container top and bottom parts being connected along their periphery in gastight fashion to corresponding parts of a retaining device. The container bottom part with the lower part of the holding device, the seal and the container top part with the upper part of the retaining device can be connected in gastight fashion and at least one of the parts of the retaining devices has an opening to receive the bag and at least one of the parts of the retaining device has a plurality of individual projections or an encircling bead so that the minimum distance between the projections or the bead and the other part of the retaining device is greater than the thickness of the thickening elements of the bag and in that the rim of the bag with the thickening elements is held between the projectional bead and the seal.
