Problems solved by technology

[0004] In the process of tobacco leaf curing, the experts analyzed the effects of the tobacco leaf varieties, the curing characteristics of each part, the moisture content of the tobacco leaves, the amount of tobacco filling, the density of tobacco filling, the opening of the fan, the temperature, and the humidity on the yellowing and drying of the tobacco leaves. Interaction, only qualitative guidance, but no quantitative guidance, therefore, it is difficult to accurately grasp the temperature, humidity and baking time of each stage

Embodiment Construction

[0037] The present invention is described in further detail below in conjunction with embodiment.

[0038] A method for precisely controlling the curing time of tobacco leaves in dense curing rooms, taking tobacco K326 variety as an example, the specific steps are as follows:

[0039] 1. Before each roasting, take 5-10 rods of fresh tobacco leaves for weighing, take the average weight of 5-10 rods of fresh tobacco leaves, count the number of tobacco rods of all flue-cured tobacco after roasting, and automatically calculate the amount of tobacco loaded , Smoke density, for example, taking the K326 variety as an example, the specific roasting times can be divided into: the first roasting method of the K326 variety in the large-scale intensive curing room, the second roasting method of the second-baking and the second shed leaf roasting of the K326 variety in the large-scale intensive curing room Method, roasting method of third roasting lower and middle leaves of K326 variety in...

Abstract

The invention discloses a method for accurately controlling the flue-curing time of tobacco leaves in a bulk curing barn. In the method, a tobacco leaf drying function model which relates to factors such as water content of tobacco leaves, loading density and loading amount, temperature and humidity as well as psychrometric difference, fan delivery, flue-curing time and the like is established according to the conventional material drying principle and tobacco leaf drying characteristics; according to different species, the drying model is multiplied by water loss regulation coefficients of tobacco parts and various flue-curing stages respectively, so that water loss rates of the tobacco leaves of different parts, different species and different stages can be calculated; and the flue-curing implementation scheme of the tobacco leaves of the bulk curing barn which is designed by the method for accurately controlling the flue-curing time of the tobacco leaves in the bulk curing barn according to the national technical specification for the flue-curing in bulk curing barns provides the accurate information of the temperature, humidity, time and fan startup of various flue-curing stages of the tobacco leaves for broad tobacco growers, and is the innovation and development of the traditional flue-curing method.

Description

technical field [0001] The invention relates to a tobacco leaf curing method, in particular to a method for precisely controlling the tobacco leaf curing time in dense curing rooms. Background technique [0002] Tobacco leaf curing is a weak link in tobacco leaf production in the whole country, and it is a major bottleneck in the progress of tobacco leaf production. Tobacco farmers generally believe that there is no problem in tobacco leaf cultivation, but the key is that the tobacco cannot be cured well. [0003] In the process of tobacco leaf curing, the key is to control the temperature and humidity in the curing room and the curing time of each stage. At present, the precise control of temperature and humidity can be better grasped by the automatic temperature and humidity controller, but in the process of curing The baking time of each stage has not yet been precisely controlled. The initial baking of tobacco leaves at home and abroad is done by manually observing the d...
