AI Technical Summary
In existing pharmaceutical freeze dryers, manually rotating the threaded handle during operation can cause dust or bacteria from hands to contaminate the trays and medicines, posing a risk of contamination.
The system employs servo motor-driven limit and tension components, which work in conjunction with a Z-shaped plate and rollers to automatically unlock the sealing door. A sponge sleeve reduces the impact of rotation, and an elastic rope pulls the sealing door to avoid manual contact.
This eliminates the need for manual unlocking of the sealed door, reducing the risk of dust and bacterial contamination and improving the convenience and safety of medicine retrieval.
