Engineering Design of Supporting Facilities for High-pressure Sterilization Equipment in Animal Laboratories

In the field of animal experiments, ensuring the aseptic condition of the experimental environment is a crucial factor for the accuracy of experiments and the health of animals. High-pressure sterilization equipment serves as an indispensable "weapon" for sterilization in animal laboratories. The rational design of its supporting engineering directly affects the performance of the equipment and the overall operational efficiency of the laboratory. Guangzhou Cleanroom Construction Co., Ltd., with its profound accumulation in the production of purification equipment, will analyze the key points of the engineering design of supporting facilities for high-pressure sterilization equipment in animal laboratories for you.

Animal laboratories of different scales vary in the quantity and volume of items to be sterilized. Small laboratories usually handle relatively fewer experimental utensils and animal bedding, so a tabletop high-pressure sterilizer with a smaller capacity can be chosen. This type of equipment occupies less space and is easy to operate. However, for large animal laboratories, due to their large-scale experiments, a large number of experimental equipment, culture media, and animal waste need to be processed. Therefore, vertical or horizontal high-pressure sterilizers with large capacities should be configured to meet the demand for batch sterilization.

The items to be sterilized in animal laboratories are diverse. For items that can withstand high temperature and pressure, such as glassware and metal instruments, conventional high-pressure sterilizers can effectively sterilize them. But for some items containing components that are not resistant to high temperature, such as certain plastic products and biological products, equipment with low-temperature sterilization functions should be selected, such as ethylene oxide sterilizers or hydrogen peroxide plasma sterilizers, which can achieve sterilization while protecting the items from damage.

The placement location of high-pressure sterilization equipment should comprehensively consider the flow of people, logistics, and drainage. The equipment should be installed in an area with good ventilation, dryness, and away from heat sources and water sources to prevent the equipment from being damaged by moisture. At the same time, there should be sufficient operating space around the equipment to facilitate the loading and unloading of sterilized items by the staff. The exhaust port and drain port of the sterilization equipment should not face the passage to avoid steam and sewage from causing harm to personnel.

A large amount of steam is generated during the high-pressure sterilization process, so a good ventilation system is essential. An exhaust fan or exhaust pipeline can be installed above the equipment to timely discharge the steam, reduce the indoor humidity, prevent safety accidents caused by steam accumulation, and improve the working environment. Sufficient lighting can provide convenience for the staff's operation and avoid operational errors due to insufficient light. A combination of natural light and artificial lighting can be adopted to ensure that the working area is brightly lit.

High-pressure sterilization equipment has strict requirements for steam supply and drainage. The steam pipeline should have good thermal insulation performance to reduce the heat loss during steam transportation and ensure that the equipment obtains a stable steam pressure. The drainage pipeline should have a certain slope to avoid water accumulation and prevent the growth of microorganisms. At the same time, to avoid blockage of the drainage pipeline, a filter can be installed at the drainage port of the equipment.

High-pressure sterilization equipment has a relatively large power, so it is necessary to configure an independent power supply circuit for it to prevent voltage instability caused by sharing the circuit with other equipment. The power supply lines should use cables that are resistant to high temperature and corrosion, and good grounding protection should be provided to avoid electric leakage accidents. In addition, overload protection and short-circuit protection devices should be set in the control circuit. When the equipment malfunctions, the power supply can be cut off in a timely manner to ensure the safety of the equipment and personnel.

With the rapid development of technology, the intelligent monitoring system provides a strong guarantee for the operation of high-pressure sterilization equipment. By installing sensors such as temperature, pressure, and time on the equipment, real-time monitoring of the sterilization process can be achieved, and the data can be transmitted to the monitoring terminal. The staff can remotely view the operating status of the equipment. When the sterilization parameters are abnormal, the system will immediately issue an alarm to remind the staff to deal with it. At the same time, the intelligent monitoring system can also record the operation history of the equipment, providing data support for equipment maintenance and fault diagnosis.
