An adjustment control system and simulation method for a smoking environment simulation room

Abstract

A regulating control system for a smoking environmental simulation chamber comprises a main body test chamber, an air conditioning mechanism, a humidifying mechanism, and an air change purification mechanism, and is characterized by further comprising a secondary regulating chamber, wherein both the air conditioning mechanism and the humidifying mechanism are communicated with the main body test chamber and the secondary regulating chamber, and can be used for regulating the humiture of the main body test chamber and the secondary regulating chamber simultaneously; the main body test chamber and the secondary regulating chamber are communicated with each other through a pressure regulating mechanism, so that the pressure of the main test chamber is adjustable; an alarming mechanism and a detection control system which is used for testing whether the temperature, humidity and pressure reach the standard or not are arranged in the main body test chamber. Through the adoption of the regulating control system, the humiture and pressure linkage regulating simulation in the smoking environment can be realized, so as to simulate the climate and altitude conditions in different regions, and to overcome the defects that smoking results (cigarette combustion test results, smoking gas index test results and smoking sensory evaluation results) for same cigarettes in different regions are inconsistent due to difference of temperature, humidity, and pressure in smoking environments.

Description

technical field [0001] The invention belongs to the research field of tobacco products, and mainly relates to an adjustment control system and a simulation method of a smoking environment simulation room. Specifically, it is a smoking environment researched and developed for simulating different smoking environments (temperature, humidity, and altitude), which can adjust temperature, humidity, and pressure within a certain range. It is suitable for standardized testing and style evaluation of tobacco products and in-process products. , quality judgment, tobacco combustion and processing technology research, etc. Background technique [0002] Cigarette products, as a kind of consumer goods, are widely distributed in circulation and consumption regions. Due to the obvious differences in climate and altitude between different regions, there are large differences in the temperature, humidity and pressure during the smoking process of cigarettes. These differences (ambient temper...

AI Technical Summary

Problems solved by technology

The difference in smoking results is mainly reflected in two aspects: On the one hand, in the process of measuring cigarette burning and smoking gas indicators, the same cigarette sample, due to the differences in temperature, humidity and pressure environment in different regions, may easily cause the burning state of cigarettes Changes in cigarette smoking, which in turn affect the changes in cigarette smoking components, resulting in differences in test results; Environmental sensory evaluation of the smoking process may easily cause differences in the evaluation results of sensory indicators, which will affect the final evaluation results, which is not conducive to the development of research work such as single-brand production in different places and evaluation of quality differences in different places.

[0003] In order to make the environmental conditions of the smoking process consistent and avoid the above-mentioned differences in the smoking process, the researchers conducted related research and also applied for some related patents to solve the differences in the smoking environment. Humidity Control Experimental Chamber (Patent No.: 200620134989.6) and Experimental Chamber System with Adjustable Atmospheric Environment Pressure (Patent No.: 201110458132.5) are patents for the fact that the temperature and humidity in the test process and the atmospheric pressure conditions in the laboratory environment cannot meet the actual situation of human adjustment According to the declaration, the two patents respectively solved the problem of uniform regulation and control of pressure in different test environments under normal pressure conditions and under fixed temperature and humidity conditions. However, neither of the two patents realized the simultaneous adjustment of temperature, humidity and pressure, and could not Fully meet the different adjustment requirements of temperature, humidity and pressure caused by differences in climate and altitude conditions in different regions

However, there are certain technical difficulties in realizing temperature, humidity and pressure regulation at the same time, that is, how to realize the linkage regulation of the three, so that the local environmental pressure can meet the consistency requirements, and ensure the relative stability and control accuracy of the local environmental temperature and humidity.
