Sterile Laboratory Design Plan

Dec 10, 2020

On is used, the air exchange rate should be greater than 3 times per hour.

2. Aseptic laboratory temperature should be controlled between 15~27℃, humidity should be controlled below 50%.

3. Purification facilities for personnel and materials should be provided at the entrance of the sterile laboratory.Sterile laboratory design plan


(1) The overall structure of the sterile laboratory:

1. The buildings designed for aseptic laboratory should be sturdy and durable, easy to maintain, easy to clean, and have the ability to prevent food, food contact surfaces and inner packaging materials from being contaminated (such as harmful animals intrusion, habitat, reproduction, etc.) structure.

2. In order to prevent cross-contamination, personnel passages and material transportation passages should be set up separately. The personnel passages should be strictly implemented in accordance with the requirements of clean room passages. Each passage should be equipped with air curtains (that is, air curtains) or two-way spring doors and electronic flies (mosquitoes). ) Anti-insect facilities such as devices.

3. The spaces around pipes, doors, windows and ventilation ducts leading to the outside must be completely filled, and all windows, vents and fan openings should be equipped with protective nets.

4. The height of the aseptic laboratory should be able to meet the process and hygiene requirements, as well as the needs of equipment installation, maintenance and maintenance.

(2) The operation table of the clean laboratory  

Aseptic work area is best to use aseptic operation table or clean work table instead, it needs to be placed at the farthest place from the door.

(3) The floor of the clean laboratory. The floor of the sterile laboratory should be paved with non-toxic, non-slip, impermeable, non-absorbent, non-cracked and easy to clean and disinfect building materials (such as acid-resistant bricks, terrazzo, concrete, etc.). It should have an appropriate slope (1.0~1.5% is appropriate).

(4) Aseptic laboratory roof and ceiling

1. The roof and ceiling should be overcoated with light-colored materials that do not absorb water, have a smooth surface, are non-toxic, mold-proof, corrosion-resistant and easy to clean. Recommended reading: Design specification for clean workshop

2. There should be no auxiliary pipes for steam, water, electricity, etc. above the exposed food and food contact surfaces to prevent dust or condensed water from falling.

(5) Sterile laboratory walls, doors and windows

1. The walls of the aseptic laboratory should be constructed of light-colored materials that are non-toxic, non-absorbent, non-permeable, mildew proof, smooth and easy to clean. The height of the decoration with this material should reach the roof.

2. All door and window structures should adopt rust-proof, moisture-proof and easy-to-clean sealed frames.

(6) Sterile laboratory lighting and lighting facilities Sterile laboratory should have sufficient natural lighting or artificial lighting, the mixed illuminance of the working surface of the processing place should not be less than 300LUX, and the ingredients and filling workshop should not be less than 800LUX.

(7) Aseptic laboratory air treatment and purification facilities

1. The aseptic laboratory must be equipped with effective ventilation equipment, and the air flow direction should flow from the clean area to the unclean area. When mechanical ventilati
