Abstract

The invention discloses a contact type device for measuring the temperature of moving tobacco.The device comprises a temperature sensor, a shell and a data processing device, and the data processing device is arranged in the shell and formed by electrically connecting a data receiver, a data storage device, a power source and a switch; the temperature sensor is electrically connected with the data receiver and extends out of the shell; the data storage device is provided with a data output port; the portion, around the data processing device, inside the shell is filled with a vibration-proof material.The device can move along with the tobacco, the curve of variation of the tobacco temperature along with time and space is measured in real time, and it is helpful to achieve conversion of control of a cigarette process from result control to process control; the contact type sensors are adopted, measurement is stable and high in precision, and the requirement of continuous long-time measurement of a target can be met; the shell has the functions of waterproofness and thermal insulation, and the requirement of working in an environment of high temperature, high humidity and the like can be met; the device is simple in structure, great in operability, convenient and practical, and measured data are accurate.

Description

technical field [0001] The invention belongs to the technical field of tobacco processing and detection, and in particular relates to a device for contact-type measuring the temperature of moving tobacco. Background technique [0002] During the cigarette processing process, tobacco (tobacco leaves, shredded tobacco, shredded stems, etc.) needs to undergo multiple drastic changes in temperature and humidity, especially in key processes such as rebaking, loosening, and drying of shredded tobacco, which will produce a series of complex processes. The chemical reaction affects the internal quality of cigarettes. Therefore, tobacco temperature has become one of the important indicators of cigarette process quality assessment. [0003] At present, domestic tobacco production enterprises are equipped with on-line temperature detection equipment at the outlet of the silk production line for loosening and regaining moisture, feeding, warming and humidifying, and shred drying, which ...
