Abstract
Description
Technical Field
[0001] This utility model relates to the field of heated non-combustible cigarette manufacturing technology, and more specifically, to a processing device for thin sheets produced by roller pressing. Background Technology
[0002] As a new type of tobacco product, heated tobacco products have a focus of industry attention regarding the production method of their dedicated tobacco sheets. Roll pressing is currently the mainstream method for manufacturing tobacco sheets specifically for heated tobacco cigarettes. This involves mixing tobacco powder and fiber, then uniformly mixing them with atomizing agents, flavorings, water, and other additives. The mixture is then subjected to multi-stage rolling and oven drying to obtain rolled sheets. However, the oven drying process requires a long drying time to achieve the desired moisture content, resulting in high energy consumption. Furthermore, a large amount of flavorings evaporates due to heat, leading to economic waste. Therefore, increasing the hot air drying rate of the sheets and reducing drying time are essential for lowering production costs and improving product quality.
[0003] Cold plasma technology is an emerging non-thermal food processing technology characterized by its adaptability, high efficiency, and environmental friendliness. It has attracted widespread attention due to its outstanding applications in food processing, environmental hygiene, and medical and health fields. Research shows that cold plasma treatment can etch the surface of the treated material, increasing the rate of moisture diffusion and drying speed. Utility Model Content

[0065] To further illustrate this utility model, the following embodiments will be described in detail.
[0066] Example 1
[0067] See Figures 1-2 As shown, Figure 1A schematic diagram of the structure of the roller pressing sheet processing device provided by this utility model, wherein, 2: roller pressing sheet, 31: air pump, 32: filtration system, 33: high voltage power supply, 34: cold plasma reaction chamber, 35: fan frequency conversion control system, 36: pipeline, 37: conveying system, 38: cold plasma airflow, 39: base; Figure 2 A schematic diagram (front view) of the roller pressing sheet processing device provided by this utility model, wherein 1: roller press, 11: pressure roller, 2: roller pressing sheet, 36: pipe, 37: conveying system, 38: cold plasma airflow, 4: conveyor belt.

[0087] Finally, the finished products are collected: after drying, the thin sheets undergo cooling, cutting and other subsequent processing to obtain the final roll-pressed tobacco sheets for heat-not-burn cigarettes.
[0088] Example 3
[0089] The device and working process provided in Example 1 are used, with the following differences:
[0090] Example 3: The sheet material was prepared according to the following proportions:
[0091] Powdered ingredients: 100 parts by weight of lotus leaf powder, 3 parts by weight of sodium carboxymethyl cellulose, and 4 parts by weight of added fiber; Liquid ingredients: 28 parts by weight of water, 20 parts by weight of propylene glycol, 10 parts by weight of glycerol, 3‰ of nicotine salt, and 3‰ of blueberry flavoring.

[0096] The thin sheets are placed in an oven for hot air drying at a temperature of 80°C.
[0097] Finally, the finished products are collected: after drying, the thin sheets undergo cooling, cutting and other subsequent processing to obtain the final roll-pressed tobacco sheets for heat-not-burn cigarettes.
[0098] Comparative Example
[0099] Prepare the sheet material according to the following proportions:
[0100] Powdered raw materials: 100 parts by weight of tobacco powder, 3 parts by weight of sodium carboxymethyl cellulose; 2 parts by weight of added fiber; Liquid raw materials: 30 parts by weight of water, 10 parts by weight of propylene glycol, 20 parts by weight of glycerol, and 3‰ of blueberry flavoring. After the powdered raw materials and fiber are premixed, they are mixed evenly with a solution containing atomizing agent, adhesive, water and other additives, and then fed into a roller press for five-stage roller pressing.
[0101] The thin sheets, without being treated by the cold plasma device, are placed in an oven for hot air drying at a temperature of 90°C.
[0102] Finally, the finished products are collected: after drying, the thin sheets undergo cooling, cutting and other subsequent processing to obtain the final roll-pressed tobacco sheets for heat-not-burn cigarettes.
[0103] The moisture content was measured using the oven drying method. The length of the mesh belt oven was fixed, and the drying time of the sheet was controlled by adjusting the speed of the conveyor belt. The drying time was defined as the time from the start of drying until the sheet reached the target moisture content (not exceeding 10%). The drying times of the comparative example and the three embodiments are shown in Table 1 below.
[0104] Table 1
[0105]
[0106]
[0107] The comparison shows that cold plasma treatment can significantly reduce the drying time of the roll forming sheet, and the improvement in the drying rate of the sheet is more significant as the power of the cold plasma device increases, the flow rate increases, and the processing time increases.
[0108] The tobacco sheets prepared in Examples 1-3 and the tobacco sheets prepared under conventional techniques in the comparative example were compared by gas chromatography-mass spectrometry to determine the retention of aroma components. Vanillin was used as the characteristic marker of the added blueberry flavor. The comparison results are shown in Table 2 below.
[0109] Table 2
[0110]
[0111] Although the amount of flavorings and fragrances added to cigarette sheets is relatively low, their cost accounts for a significant proportion of the production cost. Furthermore, flavorings and fragrances are highly volatile when heated. In traditional cigarette sheet production processes, to ensure that the amount of flavorings and fragrances retained in the finished sheets meets the sensory requirements for heated cigarettes, the amount added is often increased, thus increasing production costs. A comparison shows that, in different embodiments, after cold plasma treatment, as the hot air drying time in the oven is reduced, the amount of flavorings added to the sheets decreases, the retention rate increases, and the flavoring efficiency is improved.
[0112] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
