Description

Technical Field

[0001] The utility model relates to the technical field of cigarette making machines, in particular to a fluidized bed cooling system for cigarette making machines. Background Art

[0002] The high-speed cigarette making machine uses a circulating fan to output the airflow that transports the tobacco (provided to the primary air distribution, the blowing slot in the fluidized bed, etc.). Most of the airflow passes through the suction slot on the top of the fluidized bed, and then returns to the circulating fan after dust removal by the cyclone dust collector. During the operation of the circulating fan, the blades compress the air to generate heat, and the temperature of the circulating air in the fluidized bed will continue to rise until the heat generated is balanced with the heat dissipation, and the temperature rise will stop. The temperature of the circulating air in the fluidized bed is too high, resulting in low moisture content in the tobacco, which increases the crushing of the tobacco during the feeding process of the cigarette making machine. The increase in the broken tobacco rate will, on the one hand, increase the process loss rate of the process, directly affecting the cost and economic benefits of the factory; on the other hand, it will increase the weight fluctuation in the subsequent cigarette forming process, and the empty rate of cigarettes will increase significantly, which will directly affect the internal and external quality of cigarettes.
