Abstract

The invention relates to a method for detecting the optimal placement position of cigarettes in a constant-temperature and constant-humidity box, and belongs to the technical field of cigarette balance. The method comprises: evenly placing three trays in a clamping groove in the constant-temperature and constant-humidity box from top to bottom at intervals; arranging two measuring points at the front left part and the rear right part of the upper layer; the middle layer being provided with a measuring point at the geometric center; arranging two measuring points at the front right part and therear left part of the lower layer; 2 hours after the constant temperature and humidity box reaching a preset temperature and humidity condition, performing measurement, and performing continuous measurement for 10-15 hours; wherein the direction of the maximum wind speed in each measurement point is taken as the final actual measurement direction of the position; calculating the airflow velocityuniformity and the airflow velocity fluctuation degree of each measurement point; and then selecting the optimal placement position when the cigarette is balanced according to the airflow velocity uniformity and the airflow velocity fluctuation degree of each measuring point. The method is simple and reliable, the optimal cigarette placement position can be found quickly and effectively, and the method is easy to apply and popularize.

Description

technical field [0001] The invention belongs to the technical field of cigarette balance, and in particular relates to a method for detecting the best position of cigarettes in a constant temperature and humidity box. Background technique [0002] Before testing various indicators of cigarettes, it is usually necessary to put the cigarette sticks in the condition of "temperature 22 ℃, relative humidity 60%" for 48 hours before testing. In actual work, the balance of cigarette samples is basically carried out in a constant temperature and humidity chamber. [0003] The constant temperature and humidity box is composed of two parts: conditioning and humidification. The gas circulation in the box is realized by the fan or fan; the temperature adjustment of the constant temperature and humidity box is through the built-in temperature sensor in the box, collecting data, adjusting the temperature controller, connecting the air heating unit to increase the temperature or adjusting...
