Problems solved by technology

However, because the computer program is a confidential document, we do not know how the computer calculates and regulates it. At the same time, due to the influence of the ambient air pressure, the quality of the steam source and the accuracy of the online moisture meter, the computer needs to constantly adjust the temperature of the cylinder, and the cylinder Time consuming during body temperature adjustment
[0006] In the tobacco industry, the drying process as a key process of making silk has always attracted the attention of enterprises. Among them, the barrel temperature is closely related to the sensory quality of cigarettes. In terms of standard implementation, how to achieve the required cylinder temperature, there is no better way at present

Embodiment 1

[0034] A method for obtaining cylinder body temperature by calculating the dehydration capacity of KLD-2 silk dryer, comprising the following steps:

[0035] 1. On March 26, 2019, the KLD-2 wire drying machine of the 500kg / h test line was selected;

[0036] 2. Calculation of the relationship between the amount of dehydration and the temperature of the cylinder (application formula: △H=|H1-H2| / |T1-T2|);

[0037] The historical trend graphs of two batches were retrieved in the central control room. In the steady state, the hot air temperature was 115°C; the actual cylinder temperature T1=156°C and the corresponding actual dehydration volume H1=71L / h were obtained, and the actual cylinder temperature T2 =149°C and the corresponding actual dehydration capacity H2=62L / h; calculate the dehydration capacity by the actual cylinder temperature and the actual dehydration capacity △H=|H1-H2| / |T1-T2|:

[0038] That is, △H=(|71-62| / |156-149|)(L / h) / °C=8 / 7(L / h) / °C=1.286(L / h) / °C;

[0039] 3. ...

Embodiment 2

[0048] A method for obtaining cylinder body temperature by calculating the dehydration capacity of KLD-2 silk dryer, comprising the following steps:

[0049] 1. On March 13, 2019, the 3000kg / h KLD-2 wire drying machine of Guiyang Factory was selected;

[0050] 2. Calculation of the relationship between the amount of dehydration and the temperature of the cylinder (application formula: △H=|H1-H2| / |T1-T2|);

[0051] The historical trend charts of two batches were retrieved in the central control room. In the steady state, the hot air temperature was 110°C; the actual cylinder temperature T1=140°C and the corresponding actual dehydration volume H1=287L / h were obtained, and the actual cylinder temperature T2 =143°C and the corresponding actual dehydration amount H2=300L / h. Calculate the dehydration capacity △H=|H1-H2| / |T1-T2| by the actual cylinder temperature and the actual dehydration amount:

[0052] That is, △H=(|287-300| / |140-143|)(L / h) / ℃=13 / 3(L / h) / ℃=4.333(L / h) / ℃;

Abstract

The invention discloses a method for obtaining the cylinder body temperature by calculating the dewatering amount of a KLD-2 cut-tobacco drier. Firstly the designed cylinder body temperature needed for production is designed, in a historical trend chart, two groups of actual cylinder temperatures and the corresponding actual dewatering mount are selected, the dewatering capacity of per degree cylinder body temperature on pipe tobacco and the designed dewatering mount corresponding to the designed cylinder body temperature are calculated, the designed dewatering mount value obtained by calculating is input into the KLD-2cut-tobacco drier recipe library parameters, and the designed cylinder body temperature required for production is obtained. The method is not affected by environmental airpressure, the steam source quality and the accuracy of an on-line moisture meter, the problem of partial dry or partial wet of a stub bar due to improper setting is avoided, the dewatering amount corresponding to different cylinder body temperatures of the KLD-2 cut-tobacco drier can be accurately calculated, the amount of inlet water according to brand requirements can be backstepped, the accuracy of process design of the process cylinder body temperature of the KLD-2 cut-tobacco drier can be improved, and the method is suitable for the KLD-2 cut-tobacco drier with any production capacity.

Description

technical field [0001] The invention belongs to the technical field of tobacco processing, and in particular relates to a method for obtaining the cylinder body temperature by calculating the dehydration amount of a KLD-2 shred dryer. Background technique [0002] During the shredded process of tobacco leaves, the raw materials are heated, humidified, dried and other processes. The temperature and humidity are constantly changing, and the chemical composition inside the shredded leaves also changes accordingly. The change of process parameters in each process will have a certain impact on the chemical composition and sensory quality of cigarettes. The shred drying machine is the key equipment of the cigarette shred production line. Its main purpose is to dry the shredded tobacco to make its moisture meet the process requirements; at the same time, it can improve the filling power of the shredded tobacco and reduce the consumption of cigarettes. Thin plate drying machine is ...
