Description

Technical Field

[0001] The present application relates to the field of heated cigarettes, and in particular to a detector for glycerol content in reconstituted tobacco leaves of heated cigarettes and heated cigarette processing equipment. Background Art

[0002] Heated cigarettes, also known as heat-not-burn (HNB) tobacco products, are a new type of tobacco product. They work by heating tobacco to a temperature below traditional combustion to release nicotine and smoke. Because they offer a similar smoking experience to traditional cigarettes while releasing fewer harmful components, they have become a research and development hotspot for tobacco companies. Reconstituted tobacco, also known as tobacco flakes or reconstituted tobacco, is a key ingredient in the manufacture of heated cigarettes. Glycerol is often added to the manufacturing process to fully release the nicotine active ingredient in the tobacco flakes. Measuring the glycerol content in reconstituted tobacco leaves for heated cigarettes is crucial for quality monitoring and evaluation. The current heated cigarette processing machinery and equipment used to produce heated cigarettes generally uses chromatography to measure the glycerol content in reconstituted tobacco leaves by sampling reconstituted tobacco leaves; at the same time, Chinese patent CN116297412A discloses a detection method for extracting glycerol from reconstituted tobacco leaves; the above reconstituted tobacco leaf glycerol content detection methods will destroy the reconstituted tobacco leaves, and the reconstituted tobacco leaf samples need to undergo pre-processing steps such as crushing, which is time-consuming and has a significant impact on work efficiency. In addition, the existing heated cigarette processing machinery and equipment cannot continuously detect the glycerol content in tobacco sheets during the production of heated cigarette sheets. Therefore, the development of a simple and fast reconstituted tobacco leaf glycerol content detector and corresponding heated cigarette processing equipment has become a focus of industry research.

[0003] In order to solve the above technical problems, the present application provides a detector for the glycerol content in heated cigarette reconstituted tobacco leaves, comprising a shell and a microwave detection unit; the introduction baffle at the tobacco sheet detection entrance on the shell can conveniently introduce the tobacco slices into the gap channel of the microwave detection unit, and with the help of microwave detection of the microwave detection unit in the detection area, the glycerol content in the tobacco slices can be quickly detected.

[0004] The technical solutions provided in this application are as follows:

[0005] A detector for glycerol content in reconstituted tobacco leaves of heated cigarettes comprises: a housing and a microwave detection unit; the microwave detection unit is disposed within the housing and comprises: an upper microwave detection body portion and a lower microwave detection body portion disposed opposite each other; a gap channel is defined between the upper and lower microwave detection bodies; the gap channel serves as a detection area for tobacco sheets; one end of the gap channel is connected to a tobacco sheet detection inlet disposed on the housing; the other end of the gap channel extends out of the housing to form a tobacco sheet detection outlet;

[0006] In the width direction of the gap channel, both sides of the tobacco sheet detection entrance are connected with outward-extending introduction blocking bars.

[0007] Furthermore, the shell includes: an upper wall plate, a lower wall plate, a front wall plate, a rear wall plate and a baffle, the upper wall plate is installed on the upper part of the microwave detection body, and the lower wall plate is installed on the lower part of the microwave detection body; a front wall plate is provided between the upper wall plate and the lower wall plate at one opposite end, and a rear wall plate is provided between the upper wall plate and the lower wall plate at the other opposite end; the circumferential side of the baffle is respectively connected to the upper wall plate, the lower wall plate, the front wall plate and the rear wall plate; a tobacco sheet detection entrance is provided on the baffle.

[0009] The lower part of the microwave detection body comprises a first microwave sensor lower cavity module and a second microwave sensor lower cavity module; the first microwave sensor lower cavity module and the second microwave sensor lower cavity module are both distributed on one side surface of the lower wall plate.

[0010] Furthermore, one side of the introduction baffle is provided with a mounting shaft, and the mounting shaft is connected to a baffle on a side edge of the tobacco sheet detection inlet.

[0011] Furthermore, the sides of the baffle and the upper and lower front and rear wall panels have matching slot buckle structures, and the baffle and the upper and lower front and rear wall panels are connected through the slot buckle structures;

[0015] The present application provides a detector for the glycerol content in reconstituted tobacco leaves of heated cigarettes, including a shell and a microwave detection unit, which has a simple structure, a small size and is light.

[0027] The embodiments of the present application are written in a progressive manner.

[0028] like Figures 1 to 4As shown, the glycerol content detector for heating cigarette reconstituted tobacco according to the present application comprises: a shell and a microwave detection unit; the microwave detection unit is arranged in the shell, and the microwave detection unit comprises: oppositely arranged microwave detection body upper part and microwave detection body lower part, and a gap channel between the microwave detection body upper part and the microwave detection body lower part; the gap channel is a detection area of the tobacco sheet, one end of the gap channel is connected to a tobacco sheet detection inlet arranged on the shell, and the other end of the gap channel extends out of the shell to form a tobacco sheet detection outlet.

[0029] In the width direction of the gap channel, two side edges of the tobacco sheet detection inlet are connected to outwardly extended guide blocking strips.

[0030] The detector according to the present application has simple structure, small size and light weight; the use of the detector involves introducing the reconstituted tobacco for manufacturing heating cigarettes into the gap channel through the tobacco sheet detection inlet for microwave detection; by pre-adjusting the position of the guide blocking strip on the tobacco sheet detection inlet, the guide blocking strip above the detection inlet can be used as a limiting blocking strip to limit the tobacco sheet, and cooperates with the guide blocking strip below the detection inlet to effectively guide the tobacco sheet into the gap channel; when the tobacco sheet passes through the microwave detection unit, the microwave detection body upper part and the microwave detection body lower part will produce different responses due to the different glycerol content in the tobacco sheet, so that the tobacco sheet sample does not need to be pretreated in advance, thereby solving the problems existing in the existing glycerol content measurement method, i.e., most glycerol content measurement instruments will damage the heating cigarette sheet when detecting the tobacco leaf composition, and the detection result feedback speed is too slow.

[0031] Preferably, the guide blocking strip is preferably a rubber strip or a silicone strip.
