Method for stabilizing heat exchange efficiency and capacity of thin plate of cut-tobacco drier

Abstract

A method for stabilizing heat exchange efficiency and capacity of a thin plate of a cut-tobacco drier is characterized by including the first step of a method for judging the quality of steam entering the thin plate, the second step of a method for processing overheated steam entering the thin plate, and the third step of a method for processing wet steam entering the thin plate. The method has the advantages that the steam, under different quality conditions, entering the thin plate can reach the tobacco dewatering capacity meeting the process requirement, the heat exchange efficiency and capacity of the thin plate of the cut-tobacco drier are stabilized, and the homogenized processing quality of cut tobacco is ensured.

Description

Technical field [0001] The invention relates to a cigarette technology and a tobacco homogenization process, in particular to the control technology of shredded tobacco drying equipment in the tobacco shred process. Background technique [0002] With the continuous improvement of cigarette technology, there are more stringent requirements for the homogeneous processing of products, which requires that the effect of steam entering the thin plate on the dehydration of shredded tobacco must be greater during the processing of shredded tobacco of the same brand and different batches. unanimous. [0003] At present, most of the shred dryers adopt the control method of the temperature of the steam entering the sheet in order to meet the moisture requirement set at the outlet of the cut tobacco. When designing the control system, the steam entering the sheet is considered to be an ideal dry saturated steam. In the actual production process, since it is difficult to directly instal...

AI Technical Summary

Problems solved by technology

It can be seen that, under the same pressure, the heat released by the condensation of wet steam is not as high as that of dry saturated steam, resulting in a decrease in the heat transfer capacity of the thin plate

In addition, the water vapor carried in the wet steam will form a water hammer and cause impurities to deposit on the thin plate wall, reducing the heat transfer performance of the thin plate
