Description
Technical Field
The invention relates to a device and a method for adjusting the water content of cigarettes with controllable wind speed, which are used for balancing special cigarette samples (such as cigarettes with high water content and cigarettes with low water content) before analysis and detection, and can also be suitable for researching the influence of wind speed on sample adjustment.
Background
According to the regulations of national standard GB/T16447-2004/ISO 3402:1999 'atmospheric environment for regulating and testing tobacco and tobacco products', samples are required to be regulated before the analysis and detection of cigarettes are carried out. The standard specifies a conditioning environment of temperature (22.+ -. 1) ℃ and a relative humidity of 60%.+ -. 3%, and equilibrium is considered to be reached when the sample mass does not change more than 0.2% within 3 hours.
In practice, the conditioning of the cigarette samples is carried out substantially in a constant temperature and humidity laboratory or conditioning box, and rarely in a closed container filled with saturated saline solution. The constant temperature and humidity laboratory, the regulating box and the closed container of saturated saline solution can meet the regulating requirement of conventional commercial cigarettes in a bulk state, namely, the cigarettes can reach an equilibrium state within 48 hours in an environment (the temperature is 22+/-1 ℃ and the relative humidity is 60+/-3%).
The air in the closed container filled with saturated salt solution hardly circulates, and the air flow rate around the sample in the constant temperature and humidity laboratory is close to zero.
Although there is forced air flow in the regulating box, in general, the wind speed is uneven at different positions in the regulating box, and the wind speed is close to zero at some positions.
Special cigarette samples with high water content, low water content or dense stacking and the like can not reach an equilibrium state in 48 hours in a constant temperature and humidity laboratory, an adjusting box and a closed container of saturated saline solution, and the special cigarette samples need to be taken out and weighed every 3 hours according to the specification of GB/T16447-2004/ISO 3402:1999 to verify whether the equilibrium is reached, so that time and labor are wasted, and tobacco shreds at the end parts of cigarettes are easy to drop in the process of taking and weighing cigarettes, and misjudgment on whether the cigarettes reach the equilibrium is caused.
When carrying out detection on special cigarette samples with high water content, low water content or dense stacking and the like, shortening the adjustment time as much as possible on the premise of ensuring that the samples reach balance is very important in emergency detection. The constant temperature and humidity laboratory, regulating box or closed container filled with saturated salt solution used at present can not meet the requirement of shortening the regulating time, so that the requirement of sample regulation during emergency detection can not be met.
