AI Technical Summary
Existing drying technologies struggle to protect materials from contamination under enclosed conditions while preventing the spillage of liquid or solid materials, especially during freeze-drying where there is a risk of turbulence and the spillage of fine solid particles.
The drying bag, made of a flexible first plastic foil and a breathable sheet, combined with double fixed tension straps, ensures that the bag unfolds and stands upright in the support groove, providing effective heat transfer and mechanical stability, while allowing the transfer of evaporated gaseous components and avoiding direct contact between the material and the support groove.
It achieves material sealing and pollution-free operation during freeze-drying, avoids material spillage and contamination, ensures heat transfer efficiency and mechanical stability, and reduces the risk of accidental leakage.
