Tobacco online expansion and treatment device, equipment system and processing method thereof

Abstract

The invention provides a tobacco online expansion and treatment device for carrying out online continuous treatment at a lower temperature by utilizing low-cost overvoltage working gases, an equipment system and a corresponding processing method thereof. The tobacco online expansion and treatment device is an expansion air lock with a feed inlet and a discharge hole; and an air inlet communicated with an overvoltage thermal gas source is formed on an expansion air lock casing. The invention realize the online continuous treatment of tobacco instantaneous pressure release expansion conveniently and effectively and simplifies the tobacco online expansion and treatment equipment system by utilizing the expansion air lock with good sealing performance as the tobacco online expansion and treatment device. Meanwhile, compared with the prior tobacco expansion processing method, the invention not only has the advantage of low cost of working media, but also greatly reduces the operating temperature during the expansion and treatment, and is favorable for low-temperature flavor protection.

Description

Technical field: [0001] The invention relates to a shredded tobacco expansion processing system and equipment, in particular to an on-line shredded tobacco expansion processing device and equipment system for continuous shredded tobacco puffing processing by using heating gas such as overpressure steam or hot air. [0002] The present invention also relates to a method for on-line expansion treatment of shredded tobacco by using the above-mentioned on-line expansion treatment equipment system for shredded tobacco. Background technique: [0003] my country is a country dominated by flue-cured tobacco cigarettes. Compared with foreign blended cigarettes, the tar content of Chinese flue-cured tobacco cigarettes is relatively high. In order to reduce the tar content of flue-cured tobacco cigarettes, expanded cut tobacco tar reduction technology has been promoted. After the shredded tobacco is expanded, the volume becomes larger and the filling value increases. It is blended into...

AI Technical Summary

Problems solved by technology

Therefore, this device cannot realize continuous feeding, and its discharging is also difficult to realize continuous. At the same time, it needs to add a shredded tobacco output device in the working pressure tank, so that the crushing rate of the shredded tobacco material in the processing process cannot be prevented from further increasing. At the same time, it also increases the manufacturing difficulty and maintenance cost of the equipment, making it difficult to achieve large-scale industrial production

[0007] In order to reduce the crushing rate, patent 200720029526.8 also provides a static shredded tobacco expansion device, which has a simple structure, but requires a lot of labor in the production process. and cannot achieve continuous production

[0008] In addition, patent 200720029527.2 and patent 200720029526.8 need to evacuate the steam in the pressurized chamber when each batch of shredded tobacco is expanded, which results in large air consumption and serious energy waste
