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.

The invention relates to a freeze-drying system for drying products containing liquid and to a method for operating a freeze-drying system, said freeze-drying system having a vacuum chamber, in which at least one holding device for holding the products containing liquid is inserted, a coolable condenser being provided, on which liquid drawn from the product in a drying phase can be condensed from a vapor phase. According to the invention, at least one sound generator is arranged on the holding device, by means of which sound generator sound can be applied to the product during the drying phase.

A process for drying granular polymeric material, includes: dehumidifying the granular polymeric material by a first flow of gas at a first temperature of between 100° C. and 150° C.; heating the dehumidified granular polymeric material to a second temperature, greater than the first temperature; drying the granular polymeric material heated to the second temperature, by applying a predefined vacuum level.
The pressure-sealing elements include a filling unit, which includes a small tank blocked upstream and downstream by shut-off valves, as well as a discharge unit, which includes a small tank blocked upstream and downstream by respective shut-off valves.

Disclosed is a reactor and method for thermochemically degrading wet biomass without the need for prior drying, in particular microalga-rich substrates. The invention provides a vertical continuous multiphase reactor (VCMR) that simultaneously, progressively and continuously carries out the steps of evaporation, pyrolysis, gasification and combustion, in separate chambers, using indirect heating. The reactor operates at pressures below atmospheric pressure to increase thermal and productive efficiency, using a fraction of the same products as fuel to achieve thermal self-sufficiency. A system for instant evaporation at low temperature by means of adiabatic expansion is used. The reactor has high efficiency and high yield, requiring minimum space, and can be movable. The products obtained from the reactor are synthesis gas, biocarbon and bio-oils, with uses in energy, agriculture, cosmetics, health and construction. The invention also provides a method for obtaining hydrocarbons and energy from high-moisture biomass, wherein the steps are carried out continuously and the method does not need to be interrupted to add new wet biomass for conversion.
