Example aspects of a drying rack, a rotatable drying rack, and a method of drying wet objects are disclosed. The drying rack can comprise a base and a plurality of mounting post assemblies mounted to the base, each of the mounting post assemblies comprising at least one mounting post. The mounting post assemblies can comprise inner post assembly comprising an inner post and an outer post assembly comprising a primary outer post and a secondary outer post, wherein each of the inner post, primary outer post, and secondary outer post are configured to support an object above the base.

The invention relates to a drying method for polyglycollide warp-knitted support meshes for artificial skin, specifically comprising: pre-drying, deep drying, and fabric stress relaxation, which are performed sequentially. The drying method can completely remove water in polyglycollide warp-knitted support meshes as well as solvents left during the cleaning process, and can effectively maintain the properties such as tensile strength, pore size, and weight of the polyglycollide warp-knitted support meshes, thus being of great significance for the application of the polyglycollide warp-knitted support meshes in the field of medical artificial skin.

A drying apparatus for a water damaged floor structure having an intermediate layer between a surface layer and a subfloor, which drying device comprises a suction blower for, from an outlet opening in the floor structure, drawing humidified process air from the intermediate layer and heating the humidified air, and a sorption dehumidifier to receive the heated process air from the suction blower, convert it to heated dry air and, through an inlet opening in the floor structure, separate from the outlet port, force the heated dry air to the intermediate layer, where the heated dry air accumulates moisture from the floor structure and is converted to new process air which is again sucked up and heated by the suction blower in a closed process. According to the invention, the dryer has a PTC element for a sorbent block in the dehumidifier, a common housing for the suction fan and dehumidifiers, and a sound and heat insulation in the housing.

Method for preparing a membrane from fibril cellulose includes supplying fibril cellulose dispersion on a filter layer, draining liquid from a fibril cellulose dispersion by the effect of reduced pressure through the filter layer that is impermeable to fibrils of the fibril cellulose but permeable to the liquid to form a membrane sheet on the filter fabric, applying heat on the opposite side of the membrane sheet to the membrane sheet while continuing draining of the liquid through the filter layer by pressure difference over the filter layer, and removing the membrane sheet from the filter layer as a freestanding membrane.

The present invention provides a method for removing an organic solvent from starch hemostatic microspheres, comprising the following steps: 1. taking to-be-dried starch hemostatic microspheres and laying them flatly on drying trays with attention to laying them as uniformly and thinly as possible; 2. taking an adsorbent and subpackaging it into dialyzing paper bags for sealing; and 3. placing the trays and the dialyzing paper bags completed in the previous two steps on separators of a low-temperature vacuum oven in layers, setting the oven temperature at 0-20° C., then vacuumizing and keeping pressure for 15-48 hours. The method provided by the present invention can reduce organic solvent residue in the starch hemostatic microspheres to less than 0.05%, which meets the requirements of relevant standards for medical devices, thereby improving safety of products.
