Large intelligent low-temperature freezing insecticide sterilization and disinfection warehouse

Basic Principles

It adopts T.R.T insecticidal and disinfection technology, using low-temperature and dry methods to carry out insecticidal and disinfection treatment on archives. Pests and fungi are one of the important causes of archive damage, and temperature and humidity are the two basic factors that pests and fungi rely on for survival. Suitable temperature and humidity for rapid growth, development, and reproduction. On the contrary, it inhibits growth and development, and even leads to death. Long term cessation of low-temperature cultivation reduces enzyme activity, terminates normal metabolic activity, and leads to death. When pests are in the lethal temperature zone, free water inside the cells overflows into the intercellular space and freezes. As the ice crystals continue to expand, the cell membrane is mechanically damaged, and the protoplasm is dehydrated and concentrated, resulting in solidification. This solidification is irreversible, leading to the death of pests.

Feature Overview

Low temperature function: It can lower the temperature of the low-temperature freezer to below -35 ℃ within 120 minutes, from room temperature to -35 ℃, and maintain it at -35 ℃ for 48 hours before returning to room temperature.

Drying function: It has the function of eliminating water vapor in the air and maintaining the dryness of the archives (starting dehumidification when the machine is stopped and the temperature is returned to 0 ℃, and the dehumidification temperature is raised to room temperature. The humidity in the warehouse is between 45% and 65%).

Insecticidal function: It can completely kill pests (adults, larvae, eggs, pupae) in the archives, with a killing rate of 100%.

Disinfection function: It can kill microorganisms in the archives.

Protection function: During the process of insecticide disinfection, protect the archives from any physical and chemical damage.

Moisture protection function: It has drying and moisture protection functions, and can kill insects at low temperatures without being damp or dripping water.

Control function: Fully automatic control, with strong, standard, fast and other insecticidal mode selection, one click operation, unmanned management.

Monitoring function (optional): It has remote communication function, can monitor from different places, display the working status and historical records of the insecticide disinfection room at regular intervals, and can realize email and SMS alarm functions. It has a USB interface, can connect to external devices, display generated or printed data records, output lines or charts.

Historical data recording and saving function: The operating parameters of the equipment can be exported through a USB flash drive for easy understanding and mastery of the equipment's operating status, providing a basis for maintenance and upkeep of the equipment.

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

System Introduction

1. Permission management: The control system should set up two levels: operator and user. Logging into the system at different levels will result in different corresponding operation permissions. After saving the set and verified parameters, they will not be lost even if the PLC is powered off for a long time.

2. System monitoring: During the operation of the unit, relevant real-time data will be displayed on the monitoring main screen for easy viewing. Real time control of the unit can also be carried out according to its requirements.

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

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

5. Equipped with automatic and manual operation modes: the two states can operate independently or switch between each other without disturbance.

Monitoring function of large-scale intelligent low-temperature freezing insecticidal sterilization and disinfection warehouse

1. Real time display of the operating status and temperature of the insecticide disinfection room.

2. Control of insecticidal disinfection room, including functions such as cooling, constant temperature, heating and drying, and with manual/automatic control conversion.

3. The insecticidal disinfection room alarm, current alarm, historical alarm, historical data recording, parameter setting, alarm upper and lower limits, etc. can be remotely connected through a modem to display the fault status in real time.

4. Equipped with a USB interface, it can connect to external devices and display temperature data recording curves or charts generated or printed.

The application scope of large-scale intelligent low-temperature freezing insecticidal sterilization and disinfection warehouses is quite extensive, especially in fields where precious items need to be protected from pests and microorganisms. The following is a specific summary of its application scope:

1、 Archive industry

The large-scale intelligent low-temperature freezing insecticidal sterilization and disinfection warehouse has significant application value in the archival industry. Due to the fact that archival materials often contain a large amount of paper and ink, these materials can easily become breeding grounds for pests. Through low-temperature freezing technology, pests and their eggs, pupae, etc. in the archives can be effectively killed, while maintaining the original state of the archives without damage. In addition, the device can also sterilize archives, further extending their storage time.

2、 Cultural and museum industry

In the cultural and museum industry, large-scale intelligent low-temperature freezing insecticidal sterilization and disinfection warehouses also play an important role. Museums and cultural relics protection units often need to protect precious cultural relics from pests and microorganisms. These devices not only kill pests, but also keep cultural relics dry and clean, which helps with their long-term preservation and display.

3、 Book industry

Libraries and publishers also face the problem of pests and microorganisms invading books. A large intelligent low-temperature freezing insecticide sterilization and disinfection library can quickly and effectively sterilize a large number of books, ensuring their integrity and readability.
