Method, related device and system for detecting temperature field distribution during cigarette smoking

Abstract

The invention discloses a method for detecting the temperature field distribution during cigarette smoking, a single-channel temperature measuring smoking device, and a cigarette parameter and smoking temperature correlation system. The method comprises: after the cigarette to be tested is ignited, at least one thermocouple wire collects the temperature of the cigarette to be tested in real time, and a single-channel smoking machine starts smoking, wherein the cigarette to be tested is set on a cigarette of the single-channel smoking machine In the clamping unit, the thermocouple wire is set in the corresponding temperature measurement position of the cigarette to be tested; the temperature collector reads and stores the temperature data collected by the thermocouple wire in real time when the single-channel smoking machine performs a smoking action; The distribution determination unit determines the temperature field distribution map when the cigarette to be tested is smoked according to the temperature data. The invention can adjust the smoking program according to the demand, and can test the temperature field distribution when the cigarette is smoked online, the test data has good repeatability, and the cost is low.

Description

technical field [0001] The invention relates to the field of tobacco machinery and equipment, in particular to a method for detecting temperature field distribution during cigarette smoking, a single-channel temperature measuring smoking device, and a cigarette parameter and smoking temperature correlation system. Background technique [0002] The single-channel smoking device is an instrument commonly used to study the appearance of cigarette smoking (whiteness, shrinkage and drop of soot) and toxicology experiments. With the continuous development of technology in the tobacco industry, other important information during the smoking process of cigarettes has attracted more and more attention, such as the temperature field distribution during cigarette burning. The temperature field distribution during cigarette burning is not only closely related to the chemical reaction of tobacco, but also closely related to the density, draw resistance, air permeability of cigarette pape...

AI Technical Summary

Problems solved by technology

[0003] The function of the current single-channel smoking device is relatively simple, and only some routine experiments can be done, and it fails to provide important information such as the temperature field distribution when the cigarette is burned

In the prior art, the combination of quartz capillary and platinum-rhodium alloy wire is usually used to detect the burning and smoking temperature of cigarettes, or the micro-thermocouple block is used to test the bulk temperature of cigarettes during burning. Production costs are generally high
