Description

Technical Field

[0001] The invention relates to the technical field of intelligent cigar drying, and in particular to an intelligent cigar tobacco drying system and method based on programming control technology. Background Art

[0002] In recent years, the rapid rise of emerging consumer groups in China has driven the rapid growth of the domestic cigar consumer market and stimulated the development of the cigar industry and its upstream and downstream industries. At present, compared with the raw materials of high-quality cigar producing areas abroad, domestic raw materials have problems such as thicker texture, thicker veins, poor flexibility and poor combustibility. The domestic cigar market relies heavily on imported cigar tobacco raw materials, which seriously limits the development space of the domestic cigar industry. Cigar tobacco curing refers to the process in which the cigar tobacco leaves after harvest are gradually dried under natural or artificial temperature control, humidity control, ventilation and other conditions, and the chemical composition of the tobacco leaves gradually changes. It is an important process for the formation of the appearance quality and internal quality of cigar tobacco leaves, also known as the drying of cigar tobacco. At present, there are problems such as unclear drying specifications and lack of basis for determining key drying nodes in various cigar tobacco producing areas in my country. The quality of the drying results mainly depends on the maturity of the tobacco leaves, natural climatic conditions, curing equipment and technology. Different tobacco varieties, tobacco parts and tobacco uses have different requirements for the quality of the tobacco leaves after curing, so the requirements for the external environment during the drying period are quite different.

[0003] Previous studies have shown that by heating and ventilation, the temperature and humidity of the air-drying shed or air-drying room can be controlled to achieve precise control of temperature and humidity at different stages of curing. The color of the curing cigar wrapper is suitable and uniform, the tobacco leaves are thin, the oil content is sufficient, the elasticity is good, the veins are thin and smooth, the chemical composition is improved, and the combustibility is improved; in terms of sensory perception, the smoke is more delicate, the overall mellowness is good, and there is a pleasant smell. By regulating the air-drying humidity, the enzymatic browning reaction of cigar tobacco leaves can be effectively promoted and the intrinsic quality of tobacco leaves can be improved. In addition to the temperature and humidity during the air-drying period, the internal flow field of the existing cigar tobacco air-drying room still has the problem of poor uniformity, resulting in the instability of the quality of air-drying tobacco products. Optimizing and adjusting the uniformity of the internal flow field of the cigar tobacco air-drying room can effectively improve the air-drying efficiency of domestic cigar tobacco leaves and the quality of tobacco raw materials. At the same time, real-time tracking and detection of the color changes of cigar tobacco during the air-drying period can make real-time adjustments to the external environment during the air-drying period according to the progress of the air-drying.

[0004] The prior art discloses a patent with a publication number of 30N11650903810, which includes a steel structure frame fixed on a base plate; a wall panel fixed on the steel structure frame, and a top panel fixed on the top of the steel structure frame to form a roof; at least one wall panel on one side is provided with at least one exhaust fan, and each exhaust fan is adjusted by an electric angle actuator to adjust the angle of the fan baffle; a hanging component is also provided in the drying room, and the hanging component is fixedly or detachably connected to the steel structure; at least one internal circulation fan is provided on the upper side of the drying room; a network camera is provided below the internal circulation fan, and is located in the middle of the drying room; a spray pipe is provided above the hanging component, and the spray pipe is fixed on the steel structure frame; a plurality of spray heads are provided on the spray pipe; and a humidifying fan is provided on the spray pipe. Its advantages are that the fully automatic tobacco leaf drying process is realized, each cycle is precisely controlled, and the labor is greatly reduced.

[0005] As the existing devices and methods are used, the shortcomings of the technology are gradually exposed, mainly in the following aspects:

[0006] First, the existing drying system cannot control the air temperature and humidity control device with real-time data, and cannot adjust the cigar tobacco leaves to the most suitable environmental conditions at different drying stages. It is also unable to conduct real-time detection of the moisture content of the tobacco leaves during the drying period through the ventilation system to reduce the occurrence of mildew and disease.

[0007] Second, the existing air-drying system is unable to analyze the air-drying progress of tobacco leaves in different areas in real time to determine their disease and mildew conditions and key nodes during the air-drying period; it is unable to automatically untie the tobacco leaves and string them on the poles, bundle them up on the poles, and individually time and automatically change the position of each tobacco leaf during the air-drying period to ensure uniformity of air-drying.
