Issue 45/2013 - New technology for chemical drying detection was successfully developed

Recently, the "multi-layer air supply combined drying equipment" technology invented by the Industrial Product Safety Technology Center of Tianjin Inspection and Quarantine Bureau has obtained the national invention patent
.
At present, this technology has been used in the drying and storage
of chemical raw material samples and desiccant used in the inspection and quarantine work of Tianjin Port.

This technology can control the temperature and humidity of the drying room within the set value, keep it constant, and control the drying speed, drying temperature and drying time
according to the nature of different types of samples.
The storage and transfer of commonly used silica gel desiccant must be in a dry environment, and the poor sealing of the desiccant storage container and the change of internal temperature and humidity will make the silica gel desiccant fail
