People stream/material stream sterile airlock chamber

Abstract

The invention discloses a people stream / material stream sterile airlock chamber. The people stream / material stream sterile airlock chamber comprises an outer box and an inner box. The inner box is arranged in the outer box. Gaps exist between the top walls of the inner box and the outer box as well as between the right walls of the inner box and the outer box. A plenum chamber is arranged at the top of the inner box. The width of the plenum chamber is smaller than the width of the inner box. A fresh air electric valve and a fresh air fan are arranged on the top wall of the plenum chamber. The wall, making contact with the inner box, of the plenum chamber serves as a flow equalizing plate. A high-efficiency filter is arranged on the upper surface of the flow equalizing plate. A circulating fan is arranged on the right wall of the plenum chamber. An exhaust electric valve, an exhaust fan and an ozone machine are arranged on the top wall of the outer box. The exhaust electric valve, the exhaust fan and the ozone machine are located outside the plenum chamber. An air return port is formed in the bottom of the right wall of the inner box. According to the airlock chamber, two different clean areas can be effectively isolated, so that cross contamination is prevented; and in addition, thorough sterilization and dust removal can be achieved, and the requirement of a higher-cleanliness-grade pharmaceutical preparation technological process for the cleanliness is met.

Description

technical field [0001] The invention relates to the technical field of sterilization and dust removal devices in aseptic workshops, in particular to a sterile airlock room for people flow / logistics. Background technique [0002] The air lock room is a buffer room set up to maintain the cleanliness of the air in the clean room and control the positive pressure. The air lock room is usually set in two identical clean areas with different cleanliness, or between a clean area and an unclean area. The air lock room has two doors that cannot be opened at the same time. Its purpose is to isolate the air of two different clean environments, prevent polluted air from entering the clean area, and prevent cross-contamination. Air locks are divided into personnel air locks and material air locks. [0003] The commonly used air lock room method is basically the same as the current clean room method. It only serves as an ordinary buffer. When people or materials enter the aseptic room, ...

AI Technical Summary

Problems solved by technology

[0003] The commonly used air lock room method is basically the same as the current clean room method. It only serves as an ordinary buffer. When people or materials enter the aseptic room, some bacteria and microorganisms will inevitably be carried into the aseptic room. Can not meet the sterile requirements of the sterile room

With the development of the pharmaceutical industry, pharmaceutical clean rooms have increasingly stringent requirements on the control of bacteria and microorganisms in the pharmaceutical process. The traditional air lock room method can no longer meet the cleanliness requirements of higher cleanliness pharmaceutical processes.
