AI Technical Summary
Existing culture medium preparation and sterilization equipment poses a risk of radioactive aerosol leakage, is not thoroughly sterilized, and may cause radioactive contamination due to steam emissions. It also has a slow cooling rate and lacks a radioactive wastewater collection system.
It adopts a lead-sealed shielding structure, an independent steam generator and an insulation layer to form a steam circulation path that enters from the top and exits from the bottom. It uses electrically heated pure water to generate sterile saturated steam, and combines a vacuum and spray structure to ensure sealing and sterilization effect.
It effectively reduces nuclear radiation leakage, ensures thorough sterilization, prevents radioactive contamination, improves cooling efficiency, and achieves sterile environment preservation.
