Problems solved by technology

However, in terms of roasting process, the three-stage roasting process is still used at present. This roasting process is a universal technical specification. With the change of advanced roasting equipment and smoke loading methods, some of its process indicators can no longer adapt to intensive roasting. The baking process requirements of the room, especially the current baking process is mostly empirical qualitative description, with few precise quantitative process indicators, high requirements for the operator's technical experience, poor operability, large randomness in the operation process, and poor standardization. There are many human errors, and it is difficult to fully demonstrate the advantages of tobacco leaf quality
[0003] At the same time, the current intensive baking technology mainly focuses on tobacco rod weaving. Not only is the operation complicated, labor-intensive and time-consuming, but also the baking process of low-temperature yellowing and rapid drying is adopted, and the tobacco leaves are less oily and light in color. , compact structure, poor aroma quality, and less aroma, it is difficult to show the strong aroma style of tobacco leaves

Embodiment 1

[0022] Example 1, a baking process in a dense barn, using comb-type tobacco clips to install tobacco, setting 10 temperature and humidity precise control points, including the following steps:

[0023] a: After the tobacco leaves are loaded into the furnace, close the doors, windows and air inlets, ignite the fire, raise the dry bulb temperature to 36°C within 5 hours, control the wet bulb temperature to 35°C, keep the temperature stable for 5 hours until the tip of the tobacco leaves turns yellow, and the fan operates at a low speed;

[0024] b: Raise the dry bulb temperature to 38°C at a rate of 1°C in 1 hour, control the wet bulb temperature to 37°C, and keep the temperature stable for 12 hours until the tobacco leaves turn yellow by 30-40%, the leaves lose water and become slightly soft, and the fan operates at a low speed;

[0025] c: Raise the temperature of the dry bulb to 40°C at a rate of 1°C in 1 hour, control the temperature of the wet bulb at 37-36°C, and keep the t...

Embodiment 2

[0044] In Example 2, in order to verify the advantages of the present invention’s roasting process, conventional roasting was carried out using the existing tobacco rod loading method and the tobacco leaves were roasted using the present invention’s roasting process, and the economic properties were evaluated after roasting.

[0045] a: Zhengjiabo Tobacco Leaf Curing Factory, Jiayue Town, Zhucheng City, undertakes the tobacco leaf curing area of ​​1,200 mu, and has 60 curing rooms in total. From June to September 2013, experiments were carried out at this curing point, 58 of which adopted the intensive curing process of the present invention for tobacco leaf curing, and the other 2 curing rooms adopted conventional curing according to the method of loading tobacco rods.

[0046] From the point of view of the quality of tobacco leaves curing, the tobacco leaves that are packed with comb-type tobacco clips and baked according to the intensive curing process of the present inventi...

Abstract

The invention discloses a baking process for an intensive baking room. A comb type cigarette clamp is adopted for installing cigarettes, and ten temperature and humidity accurate control points are set. According to the technical scheme, operation is easy and safe, the baking process is quantized accurately, baking loss caused by human baking errors is greatly reduced, the baking step is simplified, automatic baking can be achieved by setting the dry-bulb temperatures, the wet-bulb temperatures, the temperature increase speed and the temperature stabilization time of ten key temperature points and the parameters of the air speed of a fan in the baking process, and therefore the operability is high and the labor cost is saved. Meanwhile, the baking quality of tobacco is improved through accurate control of the dry-bulb temperatures, the wet-bulb temperatures, the temperature increase speed, the temperature stabilization time and the parameters of the air speed of the fan, and the baked tobacco is bright in appearance color, sufficient in oil content, loose in structure, good in aroma and sufficient in amount.

Description

technical field [0001] The invention relates to the technical field of tobacco leaf baking, in particular to a baking process of a dense barn. Background technique [0002] In flue-cured tobacco production, curing is an important link that determines the quality of tobacco leaves, and it is also the weakest link in China's tobacco leaf production, which directly affects the sustainable development of tobacco leaf production in my country. The curing quality of tobacco leaves is mainly restricted by the quality of fresh tobacco leaves, curing equipment and curing technology. In recent years, with the development of modern tobacco agriculture and the popularization and application of advanced curing equipment, the quality of field tobacco leaves and curing equipment have been significantly improved. However, in terms of roasting process, the three-stage roasting process is still used at present. This roasting process is a universal technical specification. With the change of...
