preparation example Construction

[0063] Such as figure 2 Shown, the preparation method of cigarette cooling tube of the present invention comprises the following steps:

[0064] (1) Obtain the functional carrier 3, use the functional material loading device to load the cooling layer 4 on the first side of the functional carrier 3, and load the moisture-proof layer 2 on the second side of the functional carrier 3.

[0065] (2) Obtain the shell layer so that the functional carrier 3 is connected to the inner wall of the shell layer through the moisture-proof layer 2, and roll the shell layer, the moisture-proof layer 2, the functional carrier 3 and the cooling layer 4 together to form a cooling tube for cigarettes.

[0066] In a specific embodiment, the shell layer and the functional carrier 3 loaded with the moisture-proof layer 2 and the cooling layer 4 are drawn together at the same position on a transmission rod with a certain diameter for rolling to form a cooling tube for cigarettes. Wherein, the coolin...

Abstract

The invention discloses a cooling pipe for a cigarette, a preparation method of the cooling pipe and the cigarette with the cooling pipe. The cooling pipe for the cigarette is in a hollow pipe shape.The cooling pipe for the cigarette sequentially comprises a shell, a damp-proof layer, a functional carrier and a cooling layer from outside to inside. The cooling layer is loaded on the first side ofthe functional carrier; the damp-proof layer is loaded on the second side, opposite to the first side, of the functional carrier; the functional carrier is connected with the inner wall of the shellthrough the damp-proof layer; the damp-proof layer is used for preventing external moisture from entering the cigarette cooling pipe to be in contact with the cooling layer; and the cooling layer is used for reducing the temperature of flue gas. According to the invention, the cooling effect can be improved, and the damage to the appearance and the quality of the cigarette caused by the moisture absorption characteristic of the cooling material can be prevented.

Description

technical field [0001] The invention belongs to the field of low-temperature cigarette cooling technology and technology, and in particular relates to a cooling tube for cigarettes, a preparation method thereof, and a cigarette with the cooling tube. Background technique [0002] Because the low-temperature cigarette is shorter and the smoking part is heated throughout the heating process, although its heating temperature is much lower than the temperature at which shredded tobacco burns, the temperature of the smoke produced when it is smoked is much higher than that of traditional cigarettes. The current mainstream low-temperature cigarette brands in the international market generally have a maximum smoke temperature above 50°C (Celsius), which is located in a range that is relatively sensitive to consumer experience. If it is not controlled, excessively high temperatures may still affect smoking. Therefore, the problem of cooling is still an important issue that cannot be...
