Negative pressure tobacco perfuming system

Abstract

The invention discloses a negative-pressure tobacco perfuming system which comprises a vertically-placed charging cylinder (M), a feeding port (Mj) is formed in the upper portion of the charging cylinder (M), and a discharging port (Mc) is formed in the bottom of the charging cylinder (M). An air suction port (Xf) is formed in the cylinder wall of the upper portion of the discharging port (Mc) ofthe charging cylinder (M), a filter screen (7) is arranged at an opening of the air suction port (Xf), and the air suction port (Xf) is communicated with a circulating fan (4) through an air return pipe (9). The negative-pressure tobacco perfuming system is high in perfuming efficiency, good in perfuming uniformity and low in energy consumption, and perfuming liquid is not lost.

Description

technical field [0001] The invention belongs to the technical field of tobacco processing, and in particular relates to a negative pressure tobacco flavoring system. Background technique [0002] At present, the flavoring of shredded tobacco in the tobacco industry mostly adopts the drum system, but the structure of the drum system is complicated, the flavoring is uneven, and the suspended spice droplets are discharged with the exhaust system, which leads to waste and pollution of the environment, and at the same time leads to the flavoring and feeding of shredded tobacco The ratio is lower than the product design requirement. [0003] The patent CN203723421U adopts a vertical tube feeding system, which simplifies the feeding structure and solves the problem of the complex structure of the above system. However, the aromatization process is carried out in a trapezoidal cavity, and the nozzles spray the perfume liquid downwards, and the materials are blocked from each other,...

AI Technical Summary

Problems solved by technology

The closed system has the following problems: 1. The wet material sticks to the production equipment and affects the production efficiency

2. Moist material enters into cigarette products to form macula, which seriously affects product quality

3. When changing flavoring varieties, it is also necessary to clean the cyclone separation device and other parts of the system, resulting in a lot of waste of clean water and increased wastewater treatment work

4. During the flavoring process of shredded tobacco, the tobacco needs to be in any one of the fixed state, boiling state or fluidized state in the flavoring main system, which requires energy consumption and high energy consumption

5. Tobacco and flavoring liquid cannot form countercurrent transmission, the probability of contact and collision with tobacco materials is reduced, the uniformity of flavoring is poor, and the efficiency of flavoring is low

6. The device of the system is complicated, the cost is high, and it is difficult to use in the actual production process
