Low Temperature Freezing Insecticide and Disinfection Room For Cultural Relics

Low Temperature Freezing Insecticide and Disinfection Room For Cultural Relics

The low-temperature freezing insecticide and disinfection room for cultural relics usually consists of a freezer, a drying box and an automatic control system. The freezer is the core equipment used to achieve low-temperature freezing and insecticide. Drying ovens are used to remove moisture from cultural relics and prevent mold growth. Automatic control systems are used to control the operation of equipment and monitor the working status of equipment.

The working principle of low-temperature insecticidal equipment for cultural relics

The low-temperature freezing and insecticide disinfection room for cultural relics uses low-temperature freezing and drying methods to carry out insecticide and disinfection treatment for cultural relics. First, put the cultural relics into the freezer, lower the temperature to -40°C, and then keep it for a period of time to freeze the pests to death. Then, the cultural relics are placed in a drying box to remove moisture and prevent mold growth.

Functions of low-temperature insecticide equipment for cultural relics archives

The low-temperature freezing insecticide and disinfection chamber for cultural relics is a device used to process cultural relics and has the following functions:

1. Insecticide and disinfection function: Use low-temperature freezing and drying methods to carry out insecticide and disinfection treatment on cultural relics, effectively kill various pests and germs, ensure the integrity and safety of cultural relics, and kill all pests in archives ( adults, larvae, eggs, pupae), the killing rate is 100%.

2. Low-temperature treatment function: Use the method of isohumidity and temperature change to perform low-temperature treatment on cultural relics to maintain their original color, texture and structure and prevent them from being deformed or aged by heat.

3. Dehumidification function: It has an automatic dehumidification function, which can keep the indoor humidity of cultural relics stable and prevent the cultural relics from getting damp and mildewed.

4. Low-temperature storage function: With low-temperature storage function, cultural relics can be stored in a suitable low-temperature environment for a long time to prevent them from being affected by high temperature, moisture and other factors.

5. Automated operation control function: Fully automatic control, with powerful, standard, fast and other insecticidal mode selections, one-button operation, unmanned management, automatic operation function, which can automatically complete insecticidal disinfection, low-temperature treatment, etc. of cultural relics. Operations such as dehumidification and storage reduce errors and risks in manual operations.

6. Protection function: During the process of insecticide and disinfection, it protects cultural relics files from damage by any physical and chemical factors.

7. Low-temperature function: It can lower the low-temperature freezer to below -35°C within 120 minutes, drop from normal temperature to -35°C, maintain -35°C for 48 hours, and then rise back to normal temperature.

8. Heating function: It has the function of adjusting the slow heating of insecticide and disinfection.

9. Drying function: It has the function of eliminating water vapor in the air and maintaining the dryness of archival cultural relics (start dehumidification when the shutdown temperature returns to 0°C, and the dehumidification temperature rises to normal temperature, and the humidity in the library is between 45% and 65%).

10. Moisture-proof protection function: It has drying and moisture-proof protection functions. It can kill insects at low temperature without moisture or dripping water.

11. Monitoring function (optional): It has remote communication function, can monitor in different places, regularly displays the working status and historical records of the insecticide and disinfection room, and can realize email and SMS alarm functions. It has a USB interface and can be connected to external devices and displays Generate or print data log plots or graphs.

12. Historical data record saving function: The equipment operating parameters can be exported through a USB flash drive to facilitate understanding of the equipment operating status and provide a basis for maintenance of the equipment.

13. Remote control function (optional): On-site equipment can be operated through mobile APP software (any area on the network), and the parameter screen is consistent with the touch screen.

Operating system of low-temperature insecticide equipment for cultural relics

1. Permission management: The control system should be set up with two levels: operator and user. If you log in to the system at different levels, the corresponding operating permissions will be different. After the set and verified parameters are saved, they will not be lost even if the PLC is powered off for a long time.

2. System monitoring: When the unit is running, relevant real-time data will be displayed on the main monitoring screen for easy viewing. The unit can also be controlled in real time according to the unit's requirements.

3. Alarm record: When the system fails, the control system will display the cause of the failure and display and store it in the alarm record screen.

4. System settings: including system configuration settings, system parameter settings, alarm parameter settings, and calibration parameter settings. The setting parameters can be changed according to actual needs to meet actual requirements.

5. It is equipped with two sets of operating modes: automatic and manual: the two states can operate independently, and can also switch between each other without disturbance.

6. The operating status and temperature of the insecticide and disinfection room are displayed in real time.

7. Insecticide and disinfection room control, including cooling, constant temperature, heating and drying functions, and has manual/automatic control conversion.

8. Insecticide and disinfection room alarms, current alarms, historical alarms, historical data records, parameter settings, upper and lower alarm limits, etc. can be remotely connected through a modem to display fault status in real time.

9. With a USB interface, you can connect external devices to display, generate or print temperature data recording curves or charts.

Scope of application of low-temperature insecticide chamber for cultural relics

The low-temperature freezing insecticide and disinfection chamber for cultural relics is suitable for various types of cultural relics, including paper, wood products, ceramics, bronzes, fabrics, etc. For fragile cultural relics, such as fragile paper, silk, ivory, etc., they need to be sterilized at low temperatures to avoid damage to the cultural relics.

 Precautions

When using the low-temperature freezing insecticidal disinfection chamber for cultural relics, you need to pay attention to the following points: (1) Before the cultural relics enter the freezer, pre-treatment is required, such as removing dust and impurities on the surface, to ensure the treatment effect. (2) During the freezing process, the working status of the equipment needs to be checked regularly to ensure normal operation of the equipment. (3) During the drying process, the status of the cultural relics needs to be checked regularly to prevent damage to the cultural relics caused by excessive drying. In short, the low-temperature freezing insecticide and disinfection chamber for cultural relics is an efficient and safe method for processing cultural relics. It can effectively kill pests and mold in cultural relics and prevent damage to cultural relics.
