Problems solved by technology

[0004] At present, in the process of drying tobacco, it is often modulated according to production experience, and a set of scientific and reasonable modulation process has not been established. The tobacco produced often has opaque aroma, insufficient aroma, heavy green miscellaneous gas, Problems such as rough flue gas have affected its industrial usability and use value; in addition, the brewing facilities are limited, so it can only be made by drying tobacco in the open air or simply drying it under the eaves. These modulation methods do not have temperature regulation , Humidity adjustment, anti-exposure and fast water loss measures, especially in the autumn with low air humidity and strong sunlight, it is easy to cause excessive and blue drying, resulting in poor quality of sun-cured tobacco
In addition, once the rainy weather is encountered during hanging drying, the tobacco leaves need to be moved indoors in time, and the tobacco leaves must be moved out when the weather is fine, which requires a lot of manpower

Abstract

The invention discloses a vitrification sun-curing room for heating cigarette tobacco leaf raw materials for modulation and a modulation method. A heat insulation plate of the sun-curing room is arranged at the bottom of the tobacco sun-curing room, and a hot-air blower and temperature control equipment are arranged below the heat insulation plate. A humidifying and atomizing machine is arranged above the heat insulation plate, the tobacco sun-curing room is internally equipped with an airing rack, a ventilation and dehumidification device communicates the inside and outside, a probe of a temperature and humidity detection device is arranged on the inner side wall and / or the top of the tobacco sun-curing room and electrically connected with the input end of a controller, the top wall and / or at least the sunny side wall of the tobacco sun-curing room are / is provided with light-permeable faces and electric sunshade nets, and the controller is electrically connected with an air heater, the ventilation and dehumidification device, the humidifying and atomizing machine, the electric sunshade nets and the temperature control equipment. The method comprises the steps of tobacco penetrating and shelving, withering and yellowing, color fixing and killing-out. The closed light-permeable tobacco leaf sun-curing room and the control instrument are adopted to be matched with corresponding equipment to control the modulation process, intelligent and precise control over sun-curing is achieved, the modulated tobacco leaves are guaranteed to be uniform in color and stable in quality, and raw materials of various styles are provided for heating non-burning cigarettes.

Description

technical field [0001] The invention belongs to the technical field of tobacco preparation, and in particular relates to a vitrification drying room and a preparation method for heating cigarette tobacco raw materials, which have an accurate preparation process, can greatly shorten the preparation time, and can ensure uniform color and stable quality of the prepared tobacco leaves. Background technique [0002] With the gradual strengthening of tobacco control efforts around the world in recent years, and the concept of healthy living has been deeply rooted in the hearts of the people, under the influence of a series of tobacco control laws, policies and actions, the tobacco development environment has undergone profound and major changes, and the structure of tobacco products is moving towards diversification. Accelerate the adjustment of the direction of nationalization and smoke-free. The development of traditional smoking tobacco products is facing increasing pressure, a...
