Air gel drying equipment

Air gel drying equipmentFully contact the supercritical fluid with the dried material (liquid or solid) to dissolve the extracted material in the supercritical fluid, and then change the temperature or pressure (i.e. change the density of the supercritical fluid). The supercritical dryer causes the dried material to precipitate.
