Full-automatic dynamic tobacco moisture analysis climate chamber

摘要

A full-automatic dynamic tobacco moisture analysis climate chamber comprises an enclosed constant-temperature constant-humidity cabin, which is communicated with an air temperature and humidity processor to form an air circulation loop; a weighing platform is disposed inside the constant-temperature constant-humidity cabin, a sample delivery hanger is hung inside the constant-temperature constant-humidity cabin, at least one placement carrier is disposed below the sample delivery hanger, a sample vessel is placed on the placement carrier, the sample delivery hanger is further connected to a drive mechanism outside the constant-temperature constant-humidity cabin and the drive mechanism drives the sample delivery hanger to perform operations, to place the sample vessel on the weighing platform for weighing. The climate chamber, can minimize the test period, minimize intermediate links and human operation errors, and obtain a moisture content change rule of a tobacco sample as an important basis for performance evaluation of a tobacco humectant.
